Tool clamp for 6-layer rectangular copper wire motor stator end part connecting wire welding

Abstract

The invention belongs to the technical field of motor armature winding manufacturing, and particularly relates to a tool clamp for 6-layer rectangular copper wire motor stator end part connecting wirewelding. The tool clamp comprises an upper locking plate, a lower locking plate and a locking device, wherein the upper locking plate and the lower locking plate are coaxially arranged, and the locking device is used for fixing the upper locking plate and the lower locking plate; and the upper locking plate comprises upper locking holes, and the lower locking plate comprises lower locking holes which are arranged in one-to-one correspondence with the upper locking holes. According to the technical scheme, stator connecting wire connectors pass through the upper locking holes and the lower locking holes at the same time, and the locking plates are rotated to allow the upper locking holes and the lower locking holes to be staggered so that all the wire connectors can be fixed at one time, and effective welding is carried out after all the wire connectors are clamped; and a tool mechanism effectively carries out heat absorption and heat dissipation work, and welding is continuously carried out, so that labor is saved a lot, manpower and material resources are saved, the production cost is reduced, the production efficiency is improved, and the welding precision is controlled.

Description

technical field [0001] The invention belongs to the technical field of making motor armature windings, and in particular relates to a fixture for welding the connecting wires at the end of a 6-layer flat copper wire motor stator. Background technique [0002] The armature is an important part of the motor. The armature is composed of two main parts, the stator core and the winding, and insulating paper, impregnated varnish, insulating sleeve and other insulating materials. The armature winding is installed on the motor by winding or plugging. The enamelled copper wire on the armature, the armature and the winding are generally separated by insulating paper for insulation. [0003] With the development of the times, in order to pursue high efficiency, small volume and low noise, enamelled flat wires with rectangular cross-sections have been used as the motor windings and 72-slot stator cores for the drive motors used in electric vehicles. This kind of flat copper wire is for...

AI Technical Summary

Problems solved by technology

Due to the large number of connecting wires involved in the winding, there are many joints that need to be welded. Relying on manual welding and fixing the welding joints requires a lot of time and manpower, and the production efficiency is not high.

At the same time, since the connecting wire is a copper wire with an insulating layer, the insulating layer cannot be damaged during welding. However, the welding temperature of ordinary welding techniques such as argon arc welding is very high, and the welding point is 1600 degrees instantly. The insulating layer is easily melted by high temperature, resulting in Short circuit between layers
