Title: An improved vertically adjustable turret for machine tools
IPC: B23Q16/06
Filed: 1955-03-17
Abstract: 776,396. Machine-tool turrets. ETABLISSEMENTS A. CAZENEUVE, and BRUET, H. R. March 17, 1955 [March 20, 1954], No. 7869/55. Class 83 (3). A work or tool turret for a machine-tool, e.g. a lathe, comprises a sleeve 4 slidable on a post 3 and having a frusto-conical surface 6 on its lower end, an indexable body 11, the lower end of which is formed with a frusto-conical surface 16 of opposite inclination to the surface 6, radially-slidable members 21 with bevelled ends to engage the surfaces 6, 16, and means 9 for adjusting the body 11 relatively to the sleeve 4. A screw 9, with a graduated-head which is also knurled so that the notches may act as scaledivisions of the screw-pitch with reference to a mark on the body 11, is provided adjacent each tool-recess 12 to adjust the vertical position of the body and hence the tool, the screws being locked in position by spring-pressed teeth, Fig. 3 (not shown), engaging the knurled heads. The body is clamped against the three slides 21, and centred by their action on the divided-end of the sleeve, by turning a nut 48 clockwise to depress a co-operating threaded-member 25 connected, as by screws, to the body 11 and having a left-hand thread. The body 11 is held against rotation in indexed position during clamping by the engagement of one, two or four teeth 31 on the member 25 in slots 32 in a collar 36 on the post 3. After clamping, rotation of the body is also resisted as by cooperation between one of four pins 57 in the body and a pin 58 in the base 2 of the turret. To index the turret, the nut is rotated anticlockwise until the teeth 31 are raised out of the slots 32 and a surface 64 on the member 25 engages a surface 63 on the nut. Further rotation of the nut also rotates the member 25 and the body 11, a spring-pressed tooth 39 in the collar 36 entering a groove 40 in the member 25 for each indexed position of the latter. The upper-part of the body 11 is centred on the post 3 by a divided, frusto-conical ring 33 held on the post by a clip 34 and pressed into engagement with the member 25 by a spring 35. The sleeve 4 is raised by a spring 7 and recessed to provide a projection 10, for engagement by the screws 9, and a slot to engage a pin 5 on the post 3. Springs 24 urge the slides 21 against the sleeve 4, and a packing ring 19 is provided between the base 2 and the body 11. Axial-movement of the nut 48 is prevented by engagement between a shoulder 43,.attached by screws 47 to the nut, and washers 41, 44 on the post. A handle 52 is pivotally-mounted on the cap 49 of the nut 48, and a cylindrical cover 59 covers recesses 28 in the member 25 for the heads of the screws 9.
