PURPOSE:To make possible to mount and remove the unit with on-touch in the captioned jig for removing the burr of a watch case by fixing a workpiece to plural base parts, being connected to each other by a connecting rod, by means of springs, and providing a stirring bar separately. CONSTITUTION:A workpiece 11 is fixed to a reversal unit by a workpiece fixing spring 7. And, the undercut part 15 of a unit base 1 is mounted on the root part 10 of a jig attaching auxiliary 9 sop that the projection 16 of the unit base 1 is inserted to the part where the cutout 18 of a cap 8 is made to be agree with the cutout of the unit base upper end for setting because of the rotation of the cap 8. As the workpiece of fixing base 6 is rotated, the metal piece 2 fixed by a screw is rotated and the other metal piece is rotated through a connecting bar 3, thereby the workpiece fixing base is rotated so that the other workpiece fixing base can be simultaneously rotated. This reversal unit is attached to plural jigs fixing auxiliary 9, thereby it is possible to mount and remove the workpiece with one-touch so as to improve the productivity by use of a batch processing. |
