Abstract

The invention discloses a direct-current motor armature coil thread end segmenting tool, and relates to a low-voltage and high-current direct-current motor armature coil thread end segmenting tool. The direct-current motor armature coil thread end segmenting tool is mainly used to solve the problem of low working efficiency caused by the reason that the segmenting operation can only be performed on one coil element at one time because of large electromagnetic wire gauge and cross section and poor mechanical strength of the segmenting tool with existing motor armature coils. The direct-current motor armature coil thread end segmenting tool comprises a groove-shaped support, the two sidewalls of which are provided with two pin holes. Two L-shaped lower segmenting devices and two L-shaped upper segmenting devices are fixed into the two pin holes on the support through fixation pins respectively. A gasket is arranged between the two lower segmenting devices and a gasket is arranged between the two upper segmenting devices. The shape of the non-fixation ends of the two lower segmenting devices is matched with the shape of the lower-layer edge of the coil, and the shape of the non-fixation ends of the two upper segmenting devices is matched with the shape of the upper-layer edge of the coil. The segmenting tool in the invention has the advantages of being good in mechanical strength and long in service life; and the segmenting operation can be performed on two coil elements at one time, so that the segmenting tool is high in efficiency and is suitable for mass production.

Description

A kind of armature of direct current motor coil the end of a thread burst frock

Technical field

The present invention relates to a kind of armature coil the end of a thread burst frock, relate to specifically a kind of low-voltage, high-current armature of direct current motor coil the end of a thread burst frock.

Background technology

At present, when making the armature coil of low-voltage, high-current direct current machine, because the electromagnetic wire cross section of using is large, when electromagnetic wire is too thick, element of winding the end of a thread must excessively partly bend burst distortion in the thickness of the end of a thread, can cause armature coil the end of a thread burst difficulty.Traditional way is that a plurality of elements of winding of coil are combined, adopt burst of burst frock of even thickness, because low-voltage, high-current armature of direct current motor coil is large with electromagnetic wire sectional area, and online head part also exists thickness excessive, the burst pressure needing is large, its shortcoming is that 1. the shaping of the end of a thread burst is irregular, affects follow-up armature rule operation; 2. because burst frock is too thin, bad mechanical strength, burst frock is easily out of shape or is fractureed; If the independent burst of each element to coil strikes shape, production efficiency is low, and coil part is yielding, and coil shape is irregular.

Summary of the invention

The object of the invention is in order to overcome above-mentioned deficiency, and a kind of frock dimensionally stable providing, long service life, it is regular that coil the end of a thread is shaped, and rule is armature of direct current motor the end of a thread burst frock easily.

Technical solution of the present invention is: armature of direct current motor coil the end of a thread burst frock comprises that Yi Ge two side is provided with the groove type bearing of two pin-and-holes, under two " L " shapes, on wafer breaker and two " L " shapes, wafer breaker is fixed in two pin-and-holes on bearing by steady pin respectively, between two lower wafer breakers and between two upper wafer breakers, be equipped with packing ring, the shape on the shape of the on-fixed end of two lower wafer breakers and coil lower floor limit matches, and the shape of on-fixed end and the shape on limit, coil upper strata of two upper wafer breakers match.

Horizontal cross sectional geometry on bearing of two lower wafer breakers described in technical solution of the present invention and two upper wafer breakers and shape and the size between size and each the end of a thread of armature coil match.

Between lower wafer breaker described in technical solution of the present invention and upper wafer breaker, be provided with cover plate, cover plate is a kitchen knife form, one end of handle of a knife is fixed on bearing by steady pin, and the handle of a knife of kitchen knife form cover plate and the knife back are in a straight line fixed on the below of lower wafer breaker downwards.

The thickness of the thickness of the packing ring described in technical solution of the present invention and coil part the end of a thread matches.

The present invention adopts the burst frock of thickening, and every 2 coil parts are one group, carry out after burst strikes shape combining, and pipelining, so efficiency is high; The present invention, according to the profile layout of the end of a thread and the burst frock of dimensional requirement design specialized, guarantees that the armature coil the end of a thread profile processing is suitable, and regular shape, is convenient to armature coil and rolls off the production line; By the thickening of burst frock, frock self mechanical strength is high, has extended the useful life of frock.
