| 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. |
