Abstract

The invention relates to an automobile generator claw pole positioning clamp. The automobile generator claw pole positioning clamp comprises a connecting part, an elastic part and a mandrel. A first threaded hole connected with a main shaft of a machine tool is formed in one end face of the connecting part; one end of the elastic part is sleeved with one end of the connecting part, and other end of the elastic part is sleeved with one end of the mandrel; an inclined surface matched with a machined claw pole is disposed at the end, far from the elastic part, of the mandrel; a second threaded hole is formed in the end, far from the elastic part, of the mandrel; a third radial threaded hole is formed in the circumferential surface of the end, far from the elastic part, of the mandrel. The automobile generator claw pole positioning clamp has the beneficial effects that machining is stable, the structure is simple, dismantling and replacement are convenient, and self-centering of the claw pole can be achieved.

Description

technical field [0001] The invention relates to a pole positioning fixture for an automobile generator. Background technique [0002] Claw pole A component used in generators to reduce the magnetic flux leakage of the generator. [0003] The existing method of processing claw poles is to use ordinary lathes for processing, manual clamping, labor-intensive, and because the claw pole blanks are castings, there are defects such as sand holes, pores, and surface buildup, the processing is generally difficult. The turning tool of the lathe is easy to skip the cutting edge. After the cutting, it needs to be re-grinded and adjusted repeatedly. The processing is time-consuming and labor-intensive, which affects the production efficiency and product quality. In addition, the operator is required to sharpen the knife after the turning tool is sharpened, which requires relatively high knife sharpening skills for the operator. The training period for new employees is long and the asses...
