Claims

[Scope of utility model registration request]

A pallet exchange device that positions a rotary arm in which a pallet of a machine tool is exchanged between the table side and the setup side by an indexing rotation operation when the rotary arm is lowered, is provided so as to be freely rotatable and vertically movable; A pivot shaft to which the rotary arm is fixed to the upper end, a stopper provided on the side of the pivot shaft so as to be movable up and down, and a pivot shaft with one end pinned to the stopper and a horizontal pivot shaft. A lever pivotably pivoted at the center and a pin formed on the pivot shaft and provided at the other end of the lever are pivotably engaged, and the stopper moves in conjunction with the vertical movement of the pivot shaft. 1. A backlash removal mechanism for a pallet exchange device, comprising: an annular groove for vertically moving the stopper in the opposite direction; and a positioning block that projects from the rotary arm and can come into contact with the upper end of the stopper.
