Embodiment
The present invention is described in further detail below in conjunction with attached drawing embodiment.
A kind of mechanical processing technique of traction electric machine retaining ring in the present embodiment, the technique comprise the following steps：
(1) it is rough turn：A circular material blank, rough turn cylindrical, endoporus and end face, the unilateral 1.5mm of made allowance are taken, thickness similarly stays
The unilateral 1.5mm of surplus is stringent to control endoporus and excircle dimension；
(2) half fine turning outer circles：An annular claw is taken, passes through annular claw card blank endoporus, planar end surface turning, made allowance
Unilateral 0.5mm, the power of claw cannot be big during card endoporus, ensures roundness of external circle control within 0.1mm；
As shown in Figure 2 and Figure 3, the annular claw includes the three arc fixture blocks 1 arranged in a ring, the arc fixture block 1
