Symmetric-distribution slot type automatic rotor winding machine without hook

Abstract

The invention discloses a groove-typed self-rotor winder of doubling line without hook, which is characterized by the following: setting index mainshaft on the mainshaft rack within winding mechanismof working platform; placing upper cylinder fixing board on the mainshaft rack of upper surface of index mainshaft; setting lower cylinder fixing board on the mainshaft rack of lower surface of indexmainshaft; setting line-protective block, thread-clamping head, rivet head and scissors in the relative inside of upper and lower cylinder fixing boards from front to back. The winding mechanism contains fly-mainshaft with fly in the front, whose fly mainshaft end contains connecting case with protective head extended forwards. The invention possesses excellent active balance, which is convenientto modulate and observe each step of operating condition.

Description

technical field [0001] The invention relates to a rotor winding machine, in particular to an automatic rotor winding machine with no hook on the folding line and a slot. Background technique [0002] In the prior art, winding enameled wires into the grooves of the rotor core is mostly a manual-assisted semi-automatic method using false hooks. In this way, in the winding process, the enameled wire hook is manually placed on the false hook, and then it is wound around the "α" shape of the neck, and then the winding is continued. Every time a groove is wound, it must be wound around the "α" shape of the neck. " form a circle. After the winding is completed, cut the enameled wire hooked on the false hook on the outside of the rising piece of the commutator, and then rivet the ends of the two enameled wires into the groove of the rising piece, and then use spot welding to make it The ends of the two enameled wires are connected to the commutator. There are many deficiencies in...

AI Technical Summary

Problems solved by technology

There are many deficiencies in the rotor coil wound by this manual-assisted semi-automatic method. The most important thing is that the enameled wire is cut off in every slot on the commutator. The welding of the steering device is reliable, and the probability of forming a false weld is relatively high, resulting in a high scrap rate of the rotor coil; secondly, every time a groove is wound, it must be wound around the "α" shape of the neck and the hook is cut off and placed on the false hook. The enameled wire on the surface causes waste of enameled wire raw materials, which greatly increases the production cost; in addition, the winding process is complicated, the labor intensity is high, it is difficult to ensure the stability and consistency of the winding quality, and the production efficiency is low, which will also increase the production cost.
