The invention relates to a tool holder with plug nozzle and retainer cap with the slot cutter, and push the nozzle has a reference section, and the locking cap has a stretch fit.
In addition, the invention relates to a clamping part for receiving the tool holder with the plug socket, the nozzle and the reference nozzle and the reference nozzle forms a support at least one contact surface, and the nozzle - holder, at least one contact surface.
From DE 4322401 A1 is known a system change tool holder with the clamping part and the tool holder. The clamping part has a support leg, which it may be welded on the outer circumference of the milling roller. In the clamping parts installed plug socket. When this plug / socket ends of the ledge. To the ledge at an angle and against the direction of feed of the tool is adjacent the contact surface. In the clamping part can be installed in the tool holder. The tool holder has a plug nozzle, which can be installed in the plug socket of the clamping parts. In the assembled state of the tool holder mating surface relies on the surfaces of the clamping parts. To lock the tool holder in the clamping part applies pressure screw. The latter acts on the plug-in is ADCO holder and pulls it into the plug socket. However, the direction of action of the force of the retracting designed in such a way that insertion nozzle prismatic front surface is pressed into prismatic guide the clamping parts. Thus the centering of the tool holder relative to the clamping part.
The tool holder can be mounted cutter with a round rod. The latter during the operation takes effort and passes them to the tool holder. With the holder of the efforts transmitted then the clamping part, with most of the effort is transmitted through the connection with the stop formed between the mating surface and the contact surface. In addition, a certain component of the effort is transferred to the surfaces formed prismatic surfaces.
Such systems change tool holder are for use when removing pavement. Increasingly systems-change tool holder is also required in the development of open (Surfacemining). With large production capacity machines and high feed speeds require greater stiffness and strength of the tool.
The objective of the invention is to create a tool holder and, accordingly, the clamping part for receiving the tool holder, providing a strong and rigid support of the toolholder consider is nio based details even at high loads.
The task in relation to the tool holder is solved due to the fact that the plot is tight fixing of the nozzle and/or the reference section of plug nozzles have two contact surfaces, respectively, a support surface located at an angle to each other, and with the middle longitudinal axis of the slot cutter and the longitudinal axis of the insertion nozzle form an obtuse angle, and a support surface or support surface is oriented essentially against the direction of feed of the tool.
Thus, using the plot is tight, accordingly, reference is generated, the area of contact, through which can be optimally transmitted to the transverse forces which occur during use of the tool. In addition, with the contact surface or surfaces, respectively, of the support surface or support surfaces are statically defined and clearly defined areas of contact, providing reproducible backlash-free mounting of the tool holder. Due to the fact that the slot cutter and insert the nozzle is arranged at an obtuse angle to each other, are provided with improved transmission and tighter design.
According to a preferred variant implementation of the invention can be provided that the site is tight kept the surfaces of the whether the contact surface in the feed direction of the tool, at least partially in front of the plug nozzle. Thus, the considered variable direction of action of force when using the tool. While at the beginning of the cutting tool to remove material efforts are perceived front contact surface or surfaces, as further cutting tool all large power load is placed on the support surface or support surface, oriented against the direction of feed of the tool. Thus, this orientation of the respective bearing surfaces provides a design tool holder, optimized to load.
If in the case of a tool holder according to the invention provides that the support surface or support surface had an area shifted in the direction of the longitudinal axis of the plug nozzle relative to the contact surface or surfaces, due to the remoteness creates a lever, which can be transmitted moments.
A possible alternative of the invention is that the detachable attachment with its front side facing in the direction of feed of the tool has at least one pressure surface, the loaded pressure of the screw, and push this surface is located at an angle to the longitudinal axis of the aircraft is avnoj nozzles. By means of the screw retracting force can be transmitted plug the nozzle. Due to the fact that the screw of the front side affects plug nozzle, tool holder may be submitted in its installation position against the direction of feed of the tool and stay there, making it optimally supported in the rear.
The preferred embodiment of the invention is that the contact surface or the contact surface facing towards the free end of the insertion nozzle. Thus, the load forces acting at the beginning of the cutting tool rather towards the end of the plug nozzle, reliably removed. Thus, in particular, may be provided to the contact surface or the contact surface on the merits was held parallel to the median longitudinal axis of the slot cutter.
If the holder is designed so that the locking cap has an area that goes over the plug nozzle and the contact surface or contact surfaces are located in the serving area, it is possible to form the holder, is optimized to load. Due to the fact that the contact surface or contact surfaces are located in the serving area of the fixing nozzles, they can be reliably support it and also be vplotnuyu the point of application of effort, caused by exposure of the used cutter with a round rod. This allows reduction of the moments from the load.
With the increase of feed of the tool is changed, the resulting direction of the action force. While at the beginning of the cutting tool, the direction of action of the force rather is oriented in the radial direction, with the increase of cutting it will rotate in the direction opposite the feed direction. For reliable perception of the emerging result of the efforts according to the invention can be provided that the support surface of the support surface in the direction of the longitudinal axis of the plug nozzle partially overlapped at the contact surface or the contact surface and/or to the support surface and support surface in the direction of the longitudinal axis were brought up to the area of the locking head.
Simple design is obtained, in particular, due to the fact that the supporting surface and support surface parallel to the longitudinal axis of the insertion nozzle or essentially in the direction of the longitudinal axis.
The preferred embodiment of the invention is that the bearing surface, respectively, of the support surface and the contact surface, respectively, the contact surfaces form the corresponding healthy lifestyles the matter slide. When installing the tool holder, the last of its surfaces is mounted on the mating surfaces of the clamping parts. Then the tool holder is pulled together with the clamping part, and he's guiding slide can smoothly move in the intended position. This provides an unambiguous and reliable installation. Therefore, the guide slide is used for removal of the tool holder in its position according to the purpose. In the installation position of the tool holder is firmly connected to the clamping part, so that between these structural elements is no further movement relative to each other can not be.
The holders is a replacement part, which, preferably, can be mounted on the respective clamping parts in different positions of the milling roller. To enable a reliable distribution efforts in various installation positions according to a variant implementation of the invention provides that the supporting surface and/or the contact surface was located, respectively, on both sides of the middle transverse plane of the tool holder held in the feed direction of the tool, and/or symmetrically with respect to this average transverse plane.
The preferred option is executed the I invention consists in the fact, to the contact surface or contact surfaces were essentially parallel to the median longitudinal axis of the slot of the cutter, or to the angle between the Central longitudinal axis of the slot cutter and the contact surface or surfaces was -20�+20�. Thereby the contact surface or the contact surface can be brought close to the mount cutter, thanks to compact design is obtained.
It turned out that, in particular, at large depths of cut of the removed material rigidity of the tool holder is sufficient if the obtuse angle between the Central longitudinal axis, the mounting of the cutter and the longitudinal axis of the plug nozzle is selected in the range of 110-160�.
For reliable perception of the changing directions of the force during cutting, preferably, is provided to the surfaces of, respectively, the contact surface and the support surface, respectively, of the support surface are oriented in opposite directions, in particular, were located diametrically opposite.
The objective of the invention is also solved by using the clamping part for receiving the tool holder containing the plug socket, the nozzle and the reference nozzle. While supporting the nozzle forms a bearing with a contact surface or multiple surface is mi fit. The nozzle creates the arrester, creating additional contact surface or additional contact surface. According to the invention provides that the reference nozzle had two contact surfaces, or that the nozzle had two additional contact surface, and to the contact surface and/or additional contact surface located relative to each other at an angle prismatic, and to the contact surface or the contact surface formed with Central longitudinal axis of the plug socket obtuse angle. As already mentioned in connection with the tool holder, the prismatic surfaces or additional the prismatic surfaces can be optimally allocated to the applied shear force. The location of the contact surfaces (surfaces) at an obtuse angle to the Central longitudinal axis of the plug socket ensures an optimum distribution of effort and compact design.
The preferred manner of supporting the nozzle is oriented in the direction of feed of the tool before, and the nozzle in the direction of feed of the tool behind the longitudinal axis of the plug socket. Thereby the contact surface (the contact surface) and an additional contact surface (contact surface) are held before and that corresponds to the public, behind the longitudinal axis. Due to this distribution of surfaces creates a lever arm that reduces the applied moments from the load. Preferred additional contact surface (contact surface) of the nozzle has an area at least partially located across the direction of feed of the tool offset to the contact surfaces (surfaces) of the reference nozzle.
A possible variant of the invention consists in that the contact surface or the contact surface of the reference nozzles are at an obtuse angle to the longitudinal axis of the plug socket and/or essentially directed against the direction of feed of the tool. This orientation of the contact surfaces, respectively, of the surfaces allows you to start cutting tool to remove material to provide optimal power flow.
For secure retention of the tool holder in the clamping parts may be provided to anchor the attachment contained at least one threaded socket, then plug in the socket. In a threaded socket can be screwed a screw elements acting on the tool holder.

Figure 1 shows the clamping part 10, having a bottom side 11 with concave mounting surfaces. With these mounting surfaces of the clamping part can sit down on a cylindrical outer casing milling roller and rigidly welded thereto. With this clamping part 10 is connected to the tool holder 20.
As shown in figure 3, the clamping part 10 includes a plug socket 15, the host plug-in nozzle 21 of the holder 20. Below an embodiment of the tool holder 20 is illustrated in more detail with reference to figure 4-8.
As shown in figure 4, the holder 20 has inserted the nozzle 21, which is at an angle connected to the mixing nozzle 25. In the ideal plug-in nozzle 21 and the mixing nozzle 25 form an obtuse angle. Insertion nozzle 21 formed at the area of its front side 22 facing the Oh in the direction (v) the filing of the tool, the front surface 21.1. In this front surface 21.1 the two notches are made in such a way that they form two pressure surfaces 21.2. When this pressure surface 21.2 placed at an angle to the longitudinal axis of the plug nozzle 21. The protrusion insertion nozzle 21, the bearing pressure surface 21.2 through the side transitional sections 21.3, passes into the lateral surface of 21.4. The side surface 21.4 oriented in the direction (v) the filing of the instrument and converted to the sides of the tool. As can be seen in figure 5, the sides 21.4 moving to the area of the rear side 23 of the insertion nozzle supporting surface 21.5. While supporting surface 21.5 arranged at an angle to each other. Support surface 21.5, in turn, are connected by a transition surface 21.6 and facing in the opposite direction (v) the filing.
The retainer cap 25 provided with a socket 26 for the cutting tool in the form of a cylindrical hole. Median longitudinal axis M of the slot 26 to the cutter and the longitudinal axis L-plug nozzle ideally form an angle in the range between 100� and 160�, preferably 130�. The slot 26 to the cutter through the extension 27 of the input enters the surface 25.3 fit. The surface 25.3 fit passes radially socket 26 to the cutter. On the opposite side of the slot 26 to the cutter surface 25.3 fit goes in narrowing 25.1 cross is ecene. Narrowing 25.1 cross-section made in the form of a truncated cone and translates the side surface (25.2) of the tool holder 20 in the surface of 25.3 fit. The mixing nozzle 25 contains the area under the socket 26 for cutter two surfaces 29 of the seal, installed V-shape at an angle to each other. As can be seen in Fig.6, the surface 29 of the seal due to the inclined installation of it is directed towards the free end of the plug nozzle and simultaneously in the direction (v) the filing and pass, as shown in figure 3, in parallel or essentially parallel to the median longitudinal axis M of the slot 26 to the cutter. As shown in figure 5, the mixing nozzle 25 has a lateral extension 28 in which the end surface 29 of the seal. The surface 29 of the contact and support surfaces 21.5 directed in opposite directions.
Following execution of the clamping part 10 is illustrated in more detail with reference to Fig.7 and 8.
The clamping part 10 includes a plug socket 15, the cross section of which is adapted to the outer contour of the plug nozzle 21 of the holder 20. With the front side of the plug socket 15 is limited by the abutment of the nozzle 12. In the bottom nozzle 12 of the threaded socket 13 is made in the form of a thread. Threaded socket 13 goes into the plug socket 15. On the opposite side from the plug socket 15 threaded socket 13 Kanchev which is an extension 13.1 holes. The reference nozzle 12 includes at its upper section, located radially outside of the bearing 18 formed in one of two surfaces 18.1 fit. Both surfaces 18.1 fit are angled to each other. The installation angles of the surfaces 18.1 fit tailored to the installation surfaces 29 of the seal holder 20, so that the surface 29 of the seal holder 20 can adhere to the surfaces 18.1 fit the clamping parts 10 plane. Surface 18.1 fit for a particular fit of tool holder 20 are connected to each other ledge 18.4 shifted back.
On the rear side of the plug socket 15 is limited by the counter 16. The holder 16 is part of the rear nozzle 17, protruding above the plug socket 15 against the direction (v) the filing. The holder 16 is formed with two additional surfaces 16.1 fit, arranged at an angle to each other. These additional surfaces 16.1 fit, in turn, shape and spatial arrangement adapted to support surface 21.5 of the tool holder 20, so maybe plane fit additional supporting surfaces 21.5 to surfaces 16.1 fit. Opposite surfaces 18.1 fit plug socket 15 is limited by the free surface 18.2. In the direction (v) the filing and the instrument of the plug socket 15 is limited to two lateral connecting sections 19. Educated connecting sections 19 of the inner wall facing the plug-in slot 15, through the free surface 18.5 pass into the wall 18.6, which, in turn, is oriented in the direction (v) the filing instrument. Wall 18.6, in turn, terminate at the free surface 18.2. As clearly seen in figure 7, the nozzle 17 is made excavation 17.1.
Installation of the tool holder 20 on the clamping part 10 is as follows.
First, the tool holder 20 of its plug-in nozzle 21 is installed in the plug socket 15 of the clamping part 10. Then, as seen in figure 3, the threaded socket 13 as a fixing element 14 is screwed into the setscrew. The fastening element 14 has a clamping surface adjacent to the pressure surface 21.2 of the tool holder 20. When this clamping surface need not be flat, but should also be spherical. Figure 1 shows that for fixing the tool holder 20 are two of the fastening element 14, however, in the clamping parts 10 are also two threaded socket 13. When tightening fasteners 14 of the fastening element 14 presses on a pressure surface 21.2. By installing a pressure surface 21.2 at an angle to the Central longitudinal axis of the insertion nozzle 21 of the fastening element 14 has a plug on the nozzle 21 of the pulling force. At the same time formiruet the SJ component of the force, directed against the direction (v) supply and clamping plug nozzle 21 to the holder 16. Component of the force directed along the longitudinal axis of the insertion nozzle 21, enters the surface 18.1 seal support 18 into contact with the surfaces 29 of the seal holder 20. Tightening the fasteners 14 leads now to the fact that, as clearly seen in particular in figure 3, the tool holder 20 finds support on both sides of the median longitudinal axis of the insertion nozzle 21. Bearing is created, on the one hand, using controvery 16 from the rear side of the median longitudinal axis located at the side of the insertion nozzle end of the tool holder 20, and on the other, using the support 18 from the front side of the median longitudinal axis located at the side of fixing the nozzle end of the tool holder. Thus, the surface 29 of the seal and bearing surface 21.5 placed on the holder 20 is diametrically opposed. Now the mounting screw 14 acts on the push-in nozzle 21 so that the installation of the tool holder 20 is on the anvil 18 and the holder 16. This ensures reliable and captive mounting of the tool holder 20.
In addition, figure 3 shows that the extension 13.1 holes threaded holes 13 can be used the protective element 14.1, closing the socket tool of the fastening element 14.
Ka is based item 10, and the cutter 20 is made essentially mirror-symmetrical relative to the Central transverse plane of the corresponding structural elements, passing in the direction (v) the filing. This contributes to an even transfer of load.
During operation of the cutter with a round rod of conventional design, mounted in a socket 26 for cutter, cut into disposable material, such as coal seam. When this box load mainly falls on a support consisting of support 18 and the support surface 29. During insertion of the tool in the feed (v) the holder 20 is also pressed into the holder 16. Fit tool holder 20 over a large area, which ensures a reliable transmission of force.
As can be seen in figure 3, the simple installation of the tool holder 20 on the clamping part 10, in particular, is ensured by the fact that in both the above-mentioned Central bearings (bearing 18 and arrester 16) there is only one bearing. In the area of the ledge 18.4, free surface, 18.2, walls 18.6 rear surfaces 18.5, and connecting section 19 of the plug nozzle 21 is released from the plug socket 15. Now if during the operation of the clamping part 10 is the wear surfaces 18.1 fit, the ledge 18.4 forms a space for drainage. Removal of the tool holder 20 from the ledge 18.4 case is t possible adjustment of the tool holder 20 in case of wear. While compensation for wear may occur, in particular, because the supporting surface 18.1 and additional support surface 16.1 form slideways on which the tool holder 20 can slide when pulling up. This option is run, in particular, has the advantage that the clamping part 10, as is usually required, has a lifespan of several life cycles of the holders 20. In this case neizvestnye the holders 20 can continue to securely tightened and fixed to partially worn based items.
During operation of the cutter with a round rod bounces overburden rock loosening from the holder 20 on the plot side surface of 25.2. This overburden rock is served outside on the expanders 28, thereby protecting the clamping part 10 from the abrasive effect of the overburden.
When the wear of the cutter with a round rod it can simply be replaced. This is possible because the notches 17.1 in the clamping part 10 together with the notch 24 in the tool holder 20 form a socket for the tool. It can be installed puller, acting on the rear side of the cutter with a round rod and eject it from the slot 26 to the cutter. As can be seen in figure 5, the socket 26 for cutter spatially connected with the notch 24.
