[0032] As a preferred embodiment, refer to Figure 3 and Figure 4 The width of the positioning member 320 is equal to the thickness of the commutating sheet 132.

During the measurement of the welding point depth, the placement position of the welding point to be measured needs to be ensured to be the uppermost. Generally, the position of the welding point to be measured is determined by naked eye observation, but the placement position of the welding point to be measured is prone to deviation, which causes the measured data to be inconsistent with the actual value. In addition, the position of the welding point to be measured needs to be determined once for each measurement of the depth of the coil 141 welding point, which is very troublesome and reduces the measurement efficiency. When the insulating part 131 is slidably inserted into the positioning cavity 321, each commutating sheet 132 is slidably inserted into each positioning slot 322 one by one, so that the position of the welding point to be measured can be ensured to be the uppermost.

After the rotor 100 is rotated by an angle, the insulating part 131 is slidably inserted into the positioning cavity 321, and each commutating sheet 132 is slidably inserted into each positioning slot 322 one by one, so that the depth of the next welding point to be measured can be measured. The electric armature winding welding point depth measuring aid can position the welding point to be measured, ensure that the position of the welding point to be measured is the uppermost, and does not need to determine the position of each welding point to be measured one by one by naked eye observation, thereby improving the measurement accuracy and efficiency of the welding point to be measured.

[0040] (2) The armature winding welding point depth measuring aid can position the rotor 100, and the rotor 100 will not rotate during the measurement of the depth of each winding 141 of the rotor 100, thereby improving the accuracy of the welding point depth measurement;
