削盤のワーククランプ装置。[Claims for Utility Model Registration] (1) A clamping mechanism is disposed on the outer periphery of a carrier disc that is rotationally driven in one direction, and clamps and holds the workpiece in the area where it passes through the processing position of the grinding wheel. The clamping state of the workpiece is released in an area separated from the processing position, and includes one cam mechanism provided at the radial center of the carrier disk, and a cam mechanism provided at the outer periphery of the carrier disk in the circumferential direction. and a plurality of clamp mechanisms provided at intervals, the cam mechanism including one drive cam fixed at a radial center position of the carrier disk, and each clamp mechanism provided on the carrier disk. a plurality of cam followers provided in association with a clamp mechanism, the drive cam having a drive cam surface consisting of a large-diameter arcuate cam surface and a small-diameter arcuate cam surface; two continuous parts of the surface are provided at a position separated from the processing position of the grinding wheel, the cam follower has a driven member that follows the drive cam surface, and the clamp mechanism is arranged on the carrier disk a fixed clamp member fixed to the carrier disk; a movable clamp member pivotally supported to the carrier disc; and an actuating rod linked to a cam follower of the cam mechanism to swing the movable clamp member. With this, the clamping mechanism is in a work clamping state when the driven member of the cam follower is on the small-diameter arc-shaped cam surface of the drive cam surface;
On the other hand, a workpiece clamping device for a grinding machine, wherein the workpiece is in an unclamped state when the driven member of the cam follower is on the large-diameter arc-shaped cam surface of the drive cam surface. (2) The drive cam is a cam plate fixed on a support shaft that rotatably supports the carrier disk, and the outer peripheral surface thereof is the drive cam surface, and the follower is , a swinging member rotatably supported by the carrier disk; and a driven roller rotatably supported by the swinging member and rolling on the drive cam surface. Work clamping device for the described grinding machine. (3) The actuation rod is provided so as to be able to reciprocate in the radial direction of the carrier disk, and its inner diameter end is linked with the cam follower, and its outer diameter end is connected to the movable clamp member. The movable clamp member has a central portion pivotally supported by the carrier disk, one end thereof being connected to the outer diameter side end of the actuating rod, and the other end being connected to the outer diameter side end of the actuating rod. 3. The workpiece clamping device for a grinding machine according to claim 1, wherein the workpiece clamping device for a grinding machine is always resiliently biased by a resilient spring.
