[0018] The technical solution of the utility model is further described below through embodiments and in conjunction with the accompanying drawings.

[0019] Example:

[0020] This embodiment provides a bottom frame processing fixture, which is used to clamp and fix the bottom frame of the energy storage device housing. Figure 1 and Figure 2 As shown, it includes two L-plates 1 arranged opposite to each other and a bridge plate 2 arranged between the two L-plates 1. A hollow 10 is arranged in the center of the bridge plate. A clamping assembly for fixing the bottom frame to the bridge plate and a limiting assembly for limiting the opening of the bottom frame are arranged at the edge of the hollow 10. The clamping assembly is a lever cylinder 3. The limiting assembly includes a height limiting assembly and a horizontal limiting assembly 4. The height limiting assembly is arranged lower than the horizontal limiting assembly. When placing the bottom frame 6, the opening of the bottom frame 6 is arranged toward the hollow 10, the opening end surface of the bottom frame 6 is against the height limiting assembly, the side wall at the opening of the bottom frame 6 is against the horizontal limiting assembly 4, and the movable end of the lever cylinder 3 is against the outer bottom surface of the bottom frame 6 to fix the bottom frame to the bridge plate. The L-plate is fixedly arranged on the processing equipment. Under the drive of the processing equipment, the L-plate can drive the bridge plate to rotate. Due to the existence of the hollow 10, when the bridge plate rotates, the outer bottom surface, front and rear side surfaces and inner bottom surface of the bottom frame can be respectively directed toward the tool to achieve processing of the four surfaces of the bottom frame.

[0021] In this embodiment, the horizontal limiter assembly 4 is arranged at the side adjacent to the hollow 10, and the side of the horizontal limiter assembly 4 facing away from the hollow 10 abuts against the inner wall of the bottom frame 6. A convex edge is also arranged on the horizontal limiter assembly 4, and the convex edge abuts against the end face of the bottom frame opening. The convex edge is used to support the end face of the bottom frame opening.

[0022] The height limiting assembly includes a bending edge limiting assembly 8, a narrow side limiting assembly 5 and a screw hole limiting assembly 9. The bending edge limiting assembly 8 includes a first limiting column and a first abutting block arranged on the side of the first limiting column, the upper end surface of the first limiting column abuts against the horizontal section of the bending portion 7 at the bottom frame opening, and the first bottom block abuts against the vertical section of the bending portion 7 at the bottom frame opening.

[0023] The narrow side limiting assembly 5 comprises a first base, and a support portion is arranged at the upper end of the first base. The support portion is in a truncated cone shape or a cylindrical shape.

[0024] The screw hole limiting assembly 9 comprises a second base, on which a protrusion matching the screw hole of the bottom frame is provided, and the protrusion extends into the screw hole of the bottom frame.

[0025] In this embodiment, the horizontal position of the bottom frame on the clamp can be limited by the horizontal limit assembly 4, and the height of the bottom frame can be limited by the cooperation of the bending edge limit assembly 8, the narrow edge limit assembly 5, the screw hole limit assembly 9 and the upper convex edge of the horizontal limit assembly to ensure that the bottom frame remains in a horizontal state. Afterwards, under the action of the lever cylinder, the bottom frame is fixed on the clamp to prevent the bottom frame from falling when the L-plate drives the bridge plate to rotate.

[0026] The specific embodiments described herein are merely examples of the spirit of the present invention. Those skilled in the art may make various modifications or additions to the specific embodiments described or replace them in similar ways, but they will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.
