Abstract
A rotary table includes a clamping mechanism including a piston driven by operating fluid in a direction of either of clamping and unclamping a brake disc, and a biasing means fixed by a case and the piston to always bias the piston in a direction of either of clamping and unclamping the brake disc by a recovery force of elastic deformation.
Claims2
A rotary table comprising:
- a case;
- a shaft rotatably arranged in the case, and is able to secure a workpiece, a jig, and the like at an end;
- a brake disc relatively, unrotatably arranged to the shaft;
- and
- a clamping mechanism for clamping the brake disc so that the shaft cannot rotate inside the case, and for unclamping the brake disc so that the shaft can rotate inside the case, the clamping mechanism comprising:
- a piston driven by operating fluid in a direction of either of clamping and unclamping the brake disc;
- and
- a biasing unit fixed by the case and the piston, always biasing the piston in a direction of either of clamping and unclamping the brake disc by a recovery force of elastic deformation.
