Claims

[Scope of utility model registration request]

A reference pin unit for positioning a workpiece, which has a support surface that supports a part of the workpiece, and a reference block that fixes the workpiece in cooperation with a clamp that presses the workpiece against the support surface, A reference pin has a pin part that protrudes from a guide hole provided in a support surface of the block and can be fitted into a reference hole drilled in a workpiece, and a piston part located in a cylinder formed in the reference block; The actuating pin is attached to the reference flock while protruding from a pin hole provided on the supporting surface to connect the cylinder to the outside air, and when pushed down by a work placed on the supporting surface, the actuating pin connects with the cylinder. Communication with the outside air is cut off, and when the reference pin is pushed down by the clamp, the air forced through the throttle valve flows into the cylinder, pushing down the piston part of the reference pin and supporting the pin part on the reference block. A reference pin unit for workpiece positioning that is characterized by being moved downwards.
