WORKPIECE FIXING JIG

摘要

A workpiece fixing jig includes: a flat-plate-shaped base plate; a reference seat that is provided on the base plate and on which a workpiece is placed; and a clamping device that clamps the workpiece in cooperation with the reference seat by applying a pressing force to the workpiece in the direction of the reference seat. The workpiece fixing jig is configured to prevent delamination of a base plate from occurring even when the base plate is made of CFRP and a fluid channel is formed in the base plate. In the workpiece fixing jig, at least the top surface and the bottom surface of the base plate are made of fiber reinforced plastic. The base plate also has an attachment hole that passes through the base plate in a thickness direction, and an insert member made of a metal is attached to the base plate such that the insert member can be inserted in the attachment hole. The insert member also has a flow path hole that functions as a fluid channel for enabling fluid to pass through the base plate.
