Novel floating positioning clamp for electric generator claw pole

Abstract

The invention relates to a novel floating positioning clamp for an electric generator claw pole. The novel floating positioning clamp for the electric generator claw pole 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; the other end of the elastic part is sleeved with one end of the mandrel; the mandrel comprises a core, a nut, a rubber ring and a floating sleeve, and the nut, the rubber ring and the floating sleeve are arranged on the core in a sleeving mode; the floating sleeve is disposed at the end, far from the elastic part, of the core; the floating sleeve is movably connected with the core; an inclined surface matched with a machined claw pole is disposed on the circumferential surface of the floating sleeve; the nut is disposed at the end, close to the elastic part, of the core; the nut is in threaded connection with the core; the rubber ring is disposed between the nut and the floating sleeve; the rubber ring is movably connected with the core; the elastic part is a rubber barrel in which a spring is arranged. The novel floating positioning clamp for the electric generator claw pole 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 novel floating positioning fixture for claw poles of generators. 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 an...
