Research on Precision Assembly Technology of Automatic Control Digital Interference Coupling

目的开展自动控制数字化的压装技术研究,以改善手工装配过盈偶件周期长、装配质量参差不齐等问题。方法通过制定电机键槽宽度测量方法,获取合适的过盈量范围;随后设计狭小空间平键压装工装,计算不同材质的压装力,仿真分析压装力的范围。结果过盈偶件过盈量为0.004~0.007 mm,合理压装力的范围为1~2.5 kN。结论通过量化过盈偶件的压装力,能够有效分析产品的传递扭矩或定位基准,为产品的关键工序提供了理论基础。

This paper aims to carry out the research of automatic control digital press fitting technology,to improve the problems including long cycles of manual assembly interference parts and uneven assembly quality level.The measurement method of motor keyway width was established to obtain the appropriate range of interference,then,the press fitting tooling of flat key in narrow space is designed to calculate the press fitting force of different materials and simulate and analyze the range of press fitting force.By editing the test program and adopting the automatic control digital press fit technology,the interference of the interference couple was 0.004-0.007 mm,and the reasonable press fit force was 1-2.5 kN.By quantifying the press fit force of the interference couple,the effective analysis of the transmission torque or positioning reference of the product can be realized,which provides a theoretical basis for the key process of the product.
