In the press machine, the entry shaft of the motor rotor is similar to the press fitting of the commutator, and the torsional strength of the insert is guaranteed by controlling the amount of interference or punching the shaft (also called anti-rotation rib). , the interference and centistokes too large or too small will affect the torsional strength of the rotor, commutator and shaft. The precision press machine can ensure the detection of unqualified products that affect the torsional strength and determine the thickness of the silicon steel sheet. Zero defects of the product; for the assembly that is accurately press-fitted to the position close to the circlip, it is difficult to unify due to the shaft length tolerance, and the press-fit position of each workpiece should be different; the fixed position of the ordinary press is press-fit, the pressure The problem that occurs is that the motor has axial displacement when it is running, which affects the running noise and stability of the motor; the precision press machine can stop when the pressure changes suddenly, so as to be close to the spring position; improve product quality; There is a risk of falling off and cracks in the press machine. The precision press machine sorts out the risky products through the pressure on-line inspection and finds potential quality risks.
