1,101,047. Lathes. SCHIESS A.G. 10 May, 1966 [15 May, 1965], No. 20601/66. Headings B3B and B3T. [Also in Division F1] - In a vertical turret lathe the drive for the face-plate comprises a rotary hydraulic motor of which the fixed member, in the form of a disc piston 5, is rigidly connected to the machine base 1 on which is mounted the face-plate 10, the rotary ring-shaped part 12 of the motor being rigidly connected to the underside of the face-plate 10 and being rotatable therewith under the action of hydraulic fluid passing through an annular pressure chamber 13 formed between the outer periphery of the disc piston 5 and the inner periphery of the ring shaped part 12. The disc piston 5 of the motor is mounted on a circular wall 4 within the outer wall 3 of the machine base. The ring 12 comprises a housing which extends radially over and under the disc piston 5 and consists of a lower ring 12a, an upper ring 12b and an intermediate ring 12c, the upper ring 12b being rigidly secured to the outer edge of a disc 9 which carries the face-plate 10. The carrier disc 9 has a central pivot 7 supported in the bore 6 of the disc piston 5 through antifriction bearings 8. In a modification an hydraulic mounting for the face-plate is provided. |
