The first positioning portion 11 and the second positioning portion 12 are sequentially passed through by the motor shaft from bottom to top, and the detection column 1 is provided with two positioning blocks 2 which are laterally penetrated on the detection column 1 and can reciprocate toward the key slot of the side wall of the motor shaft, and two notches 13 corresponding to the retaining ring groove of the motor shaft are provided on the side of the detection column 1 facing the motor shaft.
[0016] The bottom end of the above-mentioned detection column abuts against the end face of the motor end cover, and the motor shaft passes through the first positioning part and the second positioning part in sequence. The detection column is fixed to the motor end cover through the motor shaft. When the end face of the motor shaft is flush with the upper end face of the first positioning part, the motor shaft is of a qualified length. When the motor shaft passes through the first positioning part and the second positioning part normally without a large gap, the outer diameter of the motor shaft is qualified. At this time, it can be observed whether the retaining spring groove and the notch of the motor shaft correspond to each other and remain flush. If they are flush, the position and specifications of the retaining spring groove are qualified. At the same time, the positioning block is moved toward the keyway of the motor shaft. If the positioning block is normally inserted into the keyway, the keyway is qualified. The above-mentioned two positioning blocks and notches are arranged parallel to each other up and down.

The side walls of the qualified motor shaft are in contact with the second through hole and the first through hole, and the end face of the motor shaft is kept flush with the top surface of the second positioning portion. The notch is horizontally arranged on the side wall of the detection column, and it can be visually inspected at the same time whether the notch and the retaining spring groove are on the same horizontal line, and whether the upper and lower widths of the retaining spring groove are consistent with the upper and lower widths of the notch.
[0019] like Figure 2 As shown, the detection column 1 is provided with a guide groove 14 which is arranged horizontally and corresponds to the key groove on the motor output shaft. The positioning block 2 passes through the guide groove 14 and abuts against the key groove on the motor output shaft. A limit rod 15 is provided in the guide groove 14 which is arranged horizontally and perpendicular to the left and right side walls of the guide groove 14. The positioning block 2 is provided with a strip groove 21 which cooperates with the limit rod 15 and is arranged along the moving direction of the positioning block 2.
