[0027] Embodiment 1:

[0028] like Figure 1 As shown in Figure 6, a motor stator 5 measuring tool comprises a base 1, a positioning column 2, a main clamping plate 3 and a secondary clamping plate 4. The positioning column 2 is locked to the base 1 through a locking unit. The main clamping plate 3 and the secondary clamping plate 4 are respectively arranged on both sides of the positioning column 2. The main clamping plate 3 and the secondary clamping plate 4 cooperate to clamp the motor stator 5 to the positioning column 2. A positioning unit is provided on the top of the positioning column 2, and the positioning unit is used to position the motor stator 5.

[0029] The motor stator 5 measuring tool of the present embodiment adopts the positioning column 2, the main clamping plate 3 and the secondary clamping plate 4, which can not only quickly and conveniently clamp the motor stator 5, but also firmly fix the motor stator 5 without the need to subsequently adjust the position of the motor stator 5. The positioning accuracy is high, and in combination with the base 1, the motor stator 5 can be stably placed in the detection equipment, thereby improving the test efficiency.

[0030] The locking unit includes a column hole 11, a fixing hole, a blind hole 27 and a locking bolt. The column hole 11 is located at the top of the base 1 and cooperates with the bottom of the positioning column 2. The fixing hole is located at the bottom of the base 1 and is connected to the column hole 11.

The locking bolt passes through the fixing hole and cooperates with the blind hole 27 threadedly.

[0031] The positioning unit includes a positioning groove 25 and a positioning protrusion 26 . The bottom of the positioning groove 25 is arc-shaped for conforming to the motor stator 5 .
