When we are in the inner hole of the air hammer valve core, the workpiece wall is thin and long (404mm), and the inner hole and the outer circle are required to be concentric. Therefore, we have made a set of fixtures that can replace the center frame (drawings). The main body 1 is fixed on the lathe flange, and the nut 4 rotates in the forward and reverse directions to move the taper sleeve 5 axially, clamping or loosening the workpiece.
