IPC: B24B3/24
Filed: 1951-05-29
Abstract: 680,094. Sharpening drills. AMIET, O. May 29, 1951 [June 2, 1950], No. 12544/51. Class 60. An apparatus for sharpening drills, particularly twist drills, comprises a grinding wheel 1, Fig. 2, a chuck 4 to hold the drill shank, and a centering device which grips the shank of the drill and comprises a fixed sleeve 36 in which two jaws 31, Fig. 1, are slidably mounted; the jaws and the sleeve co-act in such a way that relative axial displacement between them causes the jaws to move both towards or away from each other and transversely of the sleeve axis. The jaws grip the drill shank at the root of the cone forming the sharpening surfaces and their relative movement is produced by surfaces 44, Fig. 7, in engagement with surfaces 46, Fig. 10, at the mouth of the sleeve while their transverse movement is effected by surfaces 45 and 47. The chuck 4 is mounted for pivotal movement about a horizontal axis 7a, Fig. 2, and a vertical axis 7b so that the drill may follow the movements of the centering device when the latter is oscillated in a turret 26 about an axis 42. A projection secured to the turret and a number of adjustable stops on a bracket 15 limit the angular movement of the turret to correspond with the drill face to be ground. The bracket 15 is pivotally supported about an axis 41 and is tilted forwardly about this axis into contact with an adjustable stop. screw 67 to bring the drill into contact with the grinding wheel. A screw 17a allows the bracket to be adjusted along this axis. The drill chuck is supported from an arcuate slide which can be adjusted and secured with respect to the turret 26. This slide also supports a gauge block 12, Fig. 3, and an adjustable abutment (not shown), to receive the point of the drill. These members serve to locate the drill angularly and axially and the chuck is provided with a stem 4a, Fig. 14, slidable and rotatable in a sleeve 51 to enable the drill to be adjusted. One end of the sleeve 51 is split and bevelled to clamp the stem 4a, when a nut 54 is tightened while the other end is formed with an indexing mechanism comprising a shoulder 51a having a single diametrical slot to receive two spurs 55a on a sleeve 55 forming a rotatable fit with the sleeve 51. A spring 58 holds the spurs in the slot. A fine adjustment of the axial position of the chuck relative to the sleeve 55 is obtained by means of a knurled nut 59 bearing against the shoulder 51a. The nut 59 is also used to feed the drill. A saddle 33, Fig. 2, pivotally mounted on an axis transverse to that of the sleeve 51 and pressed by a spring into contact with the jaws 31 serves as an abutment for the drill. Trueing.-A diamond tool mounted on a support designed to take the place of the jaws in the sleeve 36 is used to true the grinding wheel. The depth of cut is determined by adjustment of the screw 17.
