Abstract

The utility model 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 only can be performed on one coil element at one time because of large electromagnetic wire guage and cross section and low segmenting tool mechanical strength with existing motor armature coils. The direct-current motor armature coil thread end segmenting tool of the utility model comprise a groove-shaped support whose two sidewalls 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 dowel 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-fixed 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-fixed ends of the two upper segmenting devices is matched with the shape of the upper-layer edge of the coil. According to the segmenting tool of the utility model, advantages of good mechanical strength and long service life are realized, and the segmenting operation can be performed on two coil elements at one time, so the advantage of high efficiency is realized, and the segmenting tool 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 utility model relates to a kind of armature coil the end of a thread burst frock, relates 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 was too thick, element of winding the end of a thread must excessively partly bend the 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 with coil combine, adopt burst of burst frock of even thickness, because low-voltage, high-current armature of direct current motor coil is large with the electromagnetic wire sectional area, and online head part also exists thickness excessive, the burst pressure that needs 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. too thin owing to the burst frock, bad mechanical strength, the burst frock is out of shape easily or is fractureed; If the independent burst of each element to coil strikes shape, then production efficiency is low, and coil part is yielding, and coil shape is irregular.

Summary of the invention

The purpose of this utility model is in order to overcome above-mentioned deficiency, and a kind of frock dimensionally stable that provides, long service life, and coil the end of a thread rule that is shaped, rule is armature of direct current motor the end of a thread burst frock easily.

Technical solution of the present utility model is: armature of direct current motor coil the end of a thread burst frock comprises that a 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 be fixed in two pin-and-holes on the bearing by steady pin respectively, be equipped with packing ring between two lower wafer breakers and between two upper wafer breakers, the shape on the shape of the on-fixed end of two lower wafer breakers and coil lower floor limit is complementary, and the shape of the on-fixed end of two upper wafer breakers and the shape on limit, coil upper strata are complementary.

Two lower wafer breakers and two upper shape and the sizes of wafer breaker between the horizontal cross sectional geometry on the bearing and size and each the end of a thread of armature coil described in the technical solution of the present utility model are complementary.

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

The thickness of the thickness of the packing ring described in the technical solution of the present utility model and coil part the end of a thread is complementary.

The utility model adopts the burst frock of thickening, and per 2 coil parts are one group, carry out making up after burst strikes shape, and pipelining, so efficient is high; The utility model guarantees that according to the profile layout of the end of a thread and the burst frock of dimensional requirement design specialized the armature coil the end of a thread profile that processes is suitable, and regular shape is convenient to armature coil and is rolled off the production line; With the thickening of burst frock, frock self mechanical strength is high, has prolonged the useful life of frock.
