AI Technical Summary

Technical Problem

In the existing technology, the interference fit between the steel needle and the stator frame pin hole is insufficient, which causes the steel needle to loosen and come out, affecting the reliability and safety of the motor operation.

Method used

A pin-engraving device is designed, which forms toothed grooves on both sides of the steel pin by means of a first engraving cutter head and a second engraving cutter head, and uses a drive mechanism to control the opening and closing action of the cutter heads to improve the connection strength and stability between the steel pin and the pin hole.

Benefits of technology

This enhances the connection strength and stability between the steel pin and the stator frame pin hole, preventing the steel pin from falling off due to vibration or external force, and improving the reliability and safety of motor operation.

Abstract

一种插针咬花装置,安装在插针机的截针工位与插针工位之间,包括一个主模和多个滑块,主模的外缘周面固定连接有多个第一咬花刀头,第一咬花刀头沿主模的周向分布;每个滑块的一端均固定连接有第二咬花刀头,第二咬花刀头与第一咬花刀头一一对应设置,第二咬花刀头与第一咬花刀头在闭合状态下形成连续齿形咬合空间,用于挤压钢针两侧形成对称的齿形槽;滑块的另一端与驱动机构相连,驱动机构用于驱动滑块沿主模的径向移动,以控制第二咬花刀头与第一咬花刀头之间的开合动作。本实用新型克服了现有技术的不足,可有效提升钢针与插针孔之间的连接强度及稳定性。并能够增强钢针在插入后的抗拔性能,避免因振动或外力导致钢针脱落。
