[0019] To make the purpose, technical solutions and advantages of the present utility model clearer and more understandable, the present utility model will be further described in detail below through the drawings and embodiments. However, it should be understood that the specific embodiments described herein are only used to explain the present utility model and do not limit the scope of the present utility model. In addition, in the following description, the description of well-known structures and technologies is omitted to avoid unnecessarily confusing the concepts of the present utility model.

[0020] Refer to Figures 1 to 3 , the embodiment of the present utility model provides a clamping tooling for processing an explosion-proof motor end cover, including left and right clamping toolings 2, clamping and fixing surfaces 7, chucks 3, positioning blocks 4, pressing blocks 5 and positioning bolts 6.

[0021] The clamping and fixing surface 7 of the clamping tooling is arc-shaped and is matched with the wire outlet of the end cover.

[0022] The positioning block 4 is arc-shaped and is matched with the stop surface of the end cover.

[0023] The pressing block 5 is provided with bolt 6 holes, and the bolt 6 is provided with a nut and a gasket.

[0024] The clamping and fixing tooling for processing the end cover of the explosion-proof motor of the present utility model includes a left clamping tooling 1, a right clamping tooling 2, a clamping and fixing surface 7, a chuck 3, a positioning block 4, a pressing block 5 and a positioning bolt 6.

[0025] During the implementation process, the clamping tooling is fixed on the processing equipment through the chuck 3. The left clamping tooling 1, the right clamping tooling 2 and the positioning block 4 perform three-point positioning on the processing workpiece 8 in the horizontal direction. The positioning block 4 and the pressing block 5 perform positioning on the processing workpiece 8 in the vertical direction. The nut on the positioning bolt 6 presses and fixes the pressing block 5.

[0026] The nut on the positioning bolt 6 is an anti-slip nut to prevent the pressing block 5 from loosening.

[0027] The left clamping tooling 1 and the right clamping tooling 2 are provided with clamping and fixing surfaces. The clamping and fixing surfaces are arc-shaped and cooperate with the workpiece 8.

[0028] The left clamping tooling 1 and the right clamping tooling 2 are provided with reinforcing grooves 10. The reinforcing grooves 10 communicate with each other.
