[0007] The clamping plate is detachably installed on the base, and the clamping plate is provided with a slot opposite to the through slot.

[0008] The vertical guide sliding structure is arranged between the base and the clamping plate.

[0009] In actual design, multiple stators are placed in the positioning slot in sequence, and then the clamping plate is clamped by the cooperation of the guide hole and the guide column, and the stator is clamped by the clamping plate and the positioning plate, and the floating clamping is realized by the cooperation of the elastic seat, which avoids damage or deformation of the stator, and when the clamping plate needs to be positioned, only the positioning part needs to be fixed, so that the transfer (such as overturning, moving, etc.) of the clamping jig can be realized.

[0010] Specifically, the clamps can be arranged on the bottom plate to fix the positioning part, or the clamping pins can be arranged at the corresponding positions (for example, the clamping pins are arranged in the bottom plate, preferably the external structure is convenient for processing) to fix the positioning part.

[0011] On the contrary, the base and the clamping plate are vertically clamped, so that the angular wear caused by the existing overturning clamping is avoided, and the positioning is simpler and more stable. BRIEF DESCRIPTION OF DRAWINGS
