Technological equipment for lathe machining of large eccentric distance

The utility model discloses technological equipment for lathe machining of a large eccentric distance, which is cylindrical, an eccentric hole and a lightening hole for mounting a part to be machinedare formed in an equipment body, and the central axes of the lightening hole, the eccentric hole and the equipment body are coplanar; a step part is milled on the equipment body, the thickness of thestep part is smaller than that of the equipment body, and the lightening hole is located in the step part. A threaded hole is formed in the side wall of the step part, located in the center plane of the eccentric hole and the center plane of the lightening hole and right opposite to the eccentric part positioning hole. An eccentric hole opening is formed in one end of the eccentric hole on an extension line of a connecting line of the center of the eccentric hole and the center of the threaded hole; two circular expansion and shrinkage holes are formed in the 60-degree included angle of the two sides of the connecting
