[0019] The specific implementation of the utility model is further described in detail below with reference to the accompanying drawings.

[0020] like Figure 1-3 As shown, the motor housing terminal block punching and positioning tool of the utility model comprises a machine base 1, a material placement tray 2, a material clamping mechanism 3, and a material clamping mechanism 4;

[0021] The machine base 1 is "L" shaped; the material placing tray 2 is located on the side wall of the machine base 1, and a positioning groove 21 is provided on the top of the material placing tray 2;

[0022] The clamping mechanism 3 includes a clamping member 31 and a first fastener 32. The clamping member 31 is provided with a clamping groove 33, and the clamping groove 33 is located directly above the positioning groove 21. The clamping member 31 is detachably fixed to the top of the machine base 1 by the first fastener 32.

[0023] The clamping mechanism 4 includes a positioning rod 41 and a clamping block 42. The positioning rod 41 is provided with an external thread. The positioning rod 41 is connected to the machine base 1 and is coaxially arranged with the material placing tray 2. A first nut 412 is provided at the end of the positioning rod 41. The clamping block 42 is provided with an open connecting groove 421. The clamping block 42 is connected to the positioning rod 41 through the connecting groove 421. The clamping block 42 is located between the first nut 412 and the material placing tray 2.

[0024] The motor housing terminal block punching and positioning tool of the utility model is as follows: the clamping block 42 is removed from the positioning rod 41 along the open connection groove 421, the casing 5 to be processed is sleeved on the material placing tray 2, the terminal block 51 protruding from the inner wall of the casing 5 is clamped in the positioning groove 21, and the terminal block 51 protruding from the outer wall of the casing 5 is clamped in the clamping groove 33 of the clamping piece 31; after the casing 5 is positioned, the clamping block 42 is reinserted back into the positioning rod 41, and the casing 5 is clamped between the clamping block 42 and the side wall of the base 1 by the first nut 412, so as to avoid loosening or sliding of the casing 5 during the punching operation, thereby affecting the punching accuracy; after the punching operation of the terminal block 51 is completed, it is loosened, the first nut 412 is used to remove the clamping block 42, and then the processed casing 5 is taken out.
