Abstract

A reference block (1) is provided with a center hole (20) having a taper inner plane (23) which becomes narrower in a downward direction. A tiff sleeve (21) having a taper outer plane (27) which engages with the taper inner plane (23) by taper is supported on the reference block (1) to be movable in the shaft center direction. In locked drive, an output member (48) inserted into the stiff sleeve (21) is moved down. Then, a clamper (33) inserted into a socket hole (3) of a work pallet (2) is moved down against an elastic member (45) to the external in the radius direction by being locked, and the taper outer plane (27) of the stiff sleeve (21) engages with the taper inner plane (23) by taper.

Description

technical field [0001] The present invention relates to a clamping device for fixing a movable block such as a work pallet or a workpiece on a reference block such as the table top of a machine tool, and to a clamping system using the clamping device. Background technique [0002] As for the clamping device, conventionally, one is described in the following Patent Document 1 (Japanese Patent Laid-Open No. 3550010). The prior art thereof has been proposed by the assignee of the invention of this application, which is constructed as follows. [0003] A tapered outer peripheral surface at an upper portion of the push rod is brought into engagement with an inner peripheral surface of the ring chuck from above, and the chuck and the push rod are arranged to be movable in a radial direction with respect to the housing. Then, when the push rod is lowered relative to the collet pushed up by the pressing spring, the collet radially expands to come into close contact with the engagin...
