In a preferred embodiment: concave-convex lines are arranged on the peripheral surface of the base.
Compared with the background technology, the technical scheme has the following advantages:
1. during clamping, when two adjacent side faces of the square part are attached to two side walls of the mounting hole, the eccentric hole of the square part is just positioned on the central axis of the base, and then the cushion block and the square part are pressed and fixed together by the locking piece. Therefore, the three-jaw chuck can be directly used for fixing the base, and the machining can be finished on a common turning machine. In addition, three claws of the three-claw chuck are operated in a linkage manner, and only one operation is needed during locking and releasing, so that the three-claw chuck is very convenient and quick to produce. Thirdly, when the square part is aligned, two adjacent sides of the square part are attached to two side walls of the mounting hole, the process is very simple and convenient, the eccentric hole can be accurately positioned to the central position, the precision is good, and the square part only needs to ensure the flatness of the two sides.
2. The retaining member adopts the bolt, simple structure to can very firmly lock the cushion.
3. The corner position outside the cushion block is provided with a chamfer inclined plane, so that the locking part can directly apply locking force to the chamfer inclined plane, and the two pressing surfaces of the cushion block can automatically lean against the other two side surfaces of the square part, so that the clamping is easier and more in place.
4. The mounting hole is provided with a guide inclined plane, so that the cushion block can be conveniently installed in the mounting hole.
5. Retaining member and cushion spiro union are when loosening the retaining member like this, need not fill up the heart cushion and can drop. In actual operation, only need loosen the retaining member a little, just can remove the restriction of cushion to square part, take off the part, when adorning new part, can lock the bolt again fast, conveniently manipulate.
