Novel positioning clamp for automobile electric generator claw pole

Abstract

The invention relates to a novel positioning clamp for an automobile electric generator claw pole. The positioning clamp comprises a connecting member, an elastic part and a mandrel. A first threaded hole connected with a spindle of a machining machine tool is formed in one end face of the connecting member. One end of the connecting member is arranged at one end of the elastic part in a sleeving mode. 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, wherein the nut, the rubber ring and the floating sleeve are arranged on the core in a sleeving mode. The floating sleeve is arranged at the end, far away from the elastic part, of the core. The floating sleeve is movably connected with the core. The circumferential face of the floating sleeve is provided with an oblique face matched with the machined claw pole. The nut is arranged at the end, close to the elastic part, of the core. The nut is in threaded connection with the core. The rubber ring is arranged between the nut and the floating sleeve. The rubber ring is movably connected with the core. The elastic part is a rubber column. The positioning clamp for the automobile electric generator claw pole has the beneficial effects of being stable in machining, simple in structure, convenient to disassemble and replace, and capable of achieving self-centering of the claw pole.

Description

technical field [0001] The invention relates to a new positioning fixture for claw poles of automobile 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...
