Workpiece support device and rotary indexer

摘要

A workpiece support device (70) includes a coupling member (3) that couples a second end of a workpiece (W); a support shaft (2), the coupling member (3) provided at a first end of the support shaft (2); a frame (1) that supports the support shaft (2) axially movably and rotatably; a force generating device (5) that applies a force in an axial direction to the support shaft (2); and an axial clamping device (6) including a single pressing member (6a1) extending along the entire periphery of the support shaft (2) or a plurality of pressing members (6a1) equally arranged in a circumferential direction of the support shaft (2), the pressing member (6a1) generating a force in a radial direction while the force generating device (5) is activated, the axial clamping device (6) fixing the support shaft (2) to the frame (1) in the axial direction by the force.
