Claims

[Scope of utility model registration request]

A plurality of cam blocks for protruding and retracting positioning pins from the pallet are arranged in a line corresponding to each positioning pin and can be moved back and forth, and these cam blocks have large diameter holes and small diameter holes along the arrangement direction. When the holes are formed in a straight line, one end of the auxiliary piston, which is disposed between each cam block and has a pressure fluid supply hole passing through it in the axial direction, is inserted into the small diameter hole of one of the cam blocks. The other end is slidably inserted into the large diameter hole of the other cam block while maintaining watertightness or airtightness, and is further located on one end side of the cam blocks arranged in the above-mentioned row. The piston rod of the hydraulic cylinder for driving is slidably inserted into the large diameter hole of the cam block while maintaining watertightness or airtightness, and the piston rod is supplied with pressurized fluid that penetrates in the axial direction. When the holes are formed, branch holes are formed in the piston rod and the auxiliary histone, which branch from each pressure fluid supply hole and enter each of the large diameter holes, and are arranged in the row. A pallet positioning device characterized in that a cam block located at the other end of the cam blocks is provided with a pressing member that presses and returns the auxiliary piston and the cam block to a driving fluid pressure cylinder side.
