Welding device of copper strap wire armature

Abstract

The present invention provides a welding device of a copper strap wire armature. The welding device comprises an armature and a welding tool, the armature is located at the internal portion of the welding tool, the welding tool comprises a box body, a lifting device and a cooling medium located at the internal portion of the box body, the lifting device penetrates the external and internal portions of the box body, the armature is located at the upper end of the lifting device, one end, located in box body, of the lifting device is located at the internal portion of the cooling medium, the lower middle portion of the armature is located at the internal portion of the cooling medium, and the armature winding welding end of the armature is located above the upper surface of the cooling medium. Through a cooperation mode of the armature and the welding tool, the armature is immersed into the cooling medium for welding so as to control the temperature when the armature performs welding, ensure that the temperature of other parts of the armature except the welding portion cannot be too high, ensure that insulation paper failure and armature winding surface film melting cannot be caused,ensure the insulativity of the armature, improve the production efficiency of the armature and reduce the manufacturing cost of the armature.

Description

technical field [0001] The invention relates to the technical field of armature processing, in particular to a welding device for copper flat wire armature. Background technique [0002] With the rapid development of the automobile industry, the requirements for the automobile motor industry are getting higher and higher. In order to reduce the weight and energy consumption of the vehicle, the motor is required to reduce the volume and weight while ensuring the power. The best way to achieve this goal The fundamental way is to improve the efficiency of the motor and reduce the loss. At present, the losses that affect the efficiency of the motor mainly include copper loss, mechanical loss, iron loss and excitation loss. Among the various methods of reducing loss, the most fundamental way is to reduce the winding. The internal resistance of the motor can reduce the various losses of the motor. The main factors affecting the internal resistance of the winding are the slot full ...

AI Technical Summary

Problems solved by technology

[0003] In order to overcome the following problems in the prior art, the welding of the end of the existing copper flat wire is carried out by intermittent welding, that is, the welding current and welding time are strictly controlled, and the welding is stopped for a period of time for the cooling of the armature. The welding method seriously affects the welding efficiency of the armature, and the insulation of the armature after welding cannot be guaranteed, which seriously affects the product quality and causes the manufacturing cost of the armature to be seriously inflated
