Process method for carrying out integral soldering on armature

Abstract

The invention relates to a process method for carrying out integral soldering on an armature. Before the armature is subjected to integral soldering, a commutator pre-tinning process is added; a spiral wound gasket is used for replacing an asbestos cord; the spiral wound gasket is placed between a tin pan and the armature; the tin pan is made of titanium alloy; and a PID (Proportion Integration Differentiation) intelligent control instrument is adopted to carry out temperature control and maintenance. The commutator pre-tinning process is designed from the economy, the practicality and the manufacturability and takes an important effect in the process method for carrying out integral soldering on the armature. After the pre-tinning is carried out, the reliability of the integral soldering of the armature is improved, the pseudo soldering and the missing soldering are avoided, the repair rate of the armature is reduced and the motor quality is fundamentally improved. According to the method, the armature soldering efficiency is improved for dozens of times; the temperature control and constant temperature effects are good; the liquidity of molten tin, the welding strength and the welding reliability are improved; and the integral soldering quality of the armature is improved.

Description

technical field [0001] The invention can be applied to the welding of armature windings and commutators in mass-produced DC motors, and can also be applied to the welding of rotor windings and headgears of wound rotor asynchronous motors, and specifically relates to a process method for integral soldering of armatures. Background technique [0002] In the traditional armature winding and commutator welding process, it has been possible to achieve one-time welding, improve the soldering efficiency by dozens of times, and make requirements for the overall pre-soldering process, which can guarantee the soldering quality to a certain extent. However, this traditional process method is not perfect, and the welding reliability is not high, and false welding and missing welding may occur. In addition, the sealing effect of the asbestos rope is not ideal, and there is tin leakage, which will form a tin layer on the surface of the commutator, thereby affecting the quality of the moto...
