Description

Technical Field

[0001] This application relates to the field of cutting tooling technology, and in particular to reinforcing cutting, positioning and splicing tooling. Background Technology

[0002] Currently, the mainstream battery box manufacturing processes are aluminum alloy extrusion profile welding, steel sheet metal stamping and welding, and aluminum alloy die casting. Compared with the other two methods, aluminum alloy die casting can achieve advantages such as simple process flow, good lightweight effect, and small deformation at a relatively low cost, and has the advantages of integrated, streamlined, fewer parts, and high-efficiency manufacturing.

[0003] The main process of die casting is as follows: a blank is formed by high-vacuum die casting, and then it is precision machined to ensure the dimensional accuracy of the product. In order to further improve the impact resistance and service life of the battery shell, materials such as fiberglass cloth are cut according to the shape of the battery shell and then stacked in multiple layers on the surface of the battery shell, which is called reinforcement.

[0004] Cutting fiberglass cloth requires tooling positioning to prevent displacement during the cutting process, which would affect cutting accuracy. Traditional cutting mechanisms typically use vacuum adsorption or low-pressure platen to position the fiberglass cloth. However, due to the high rigidity of fiberglass cloth, the impact force from the cutting tools increases accordingly. These two positioning methods are prone to vibration during cutting, affecting accuracy. Even with platen pressing, the irregularity of the battery casing surface means that unstable pressing can cause the fiberglass cloth to spring back and taut from the folds of the battery casing during cutting, leading to cutting errors and scrap.

[0005] Therefore, this application provides a reinforcing cutting, positioning and splicing fixture, which enables the fiberglass cloth to adapt to the shape and size of the battery casing and remain stable during the cutting process, without shaking or shifting. Utility Model Content

A through hole one is arranged on the limiting frame 3 close to the hinge part, and a through hole two is arranged on the workbench 1 above the joint part of the limiting frame 3. The limiting frame 3 can be stably kept in the pressing position by bolts passing through the through hole one and the through hole two.

[0045] The tail end of the workbench 1 is rotatably provided with a plurality of pressing frames 4, and the limiting structure of the pressing frame 4 is the same as that of the limiting frame 3.

[0046] A plurality of reinforcing limiting frames 13 are detachably installed on the workbench 1 along the length direction. The reinforcing limiting frame 13 is plate-shaped as a whole, and the length direction two ends are provided with hanging edges connected to the workbench 1 by bolts and the like, and the bottom end shape is matched with the surface of the battery shell 2.

[0047] The bottom end of the reinforcing limiting frame 13 is provided with a bent edge 6 matching the eaves of the battery shell 2 on both sides.

[0048] According to the above technical solutions:

[0049] In use, the glass fiber cloth is straightened and laid on the surface of the battery shell 2, and then the reinforcing limiters 13 are fastened one by one to tightly press the glass fiber cloth on the surface of the battery shell 2. Then the glass fiber cloth is pulled flat, the pressing frames 4 are turned over one by one to press the pressing frames 4 on the surface of the glass fiber cloth and fasten them; then the limit frames 3 are turned over to press the bridge frames 5 on the limit frames 3 on the surface of the glass fiber and fasten them. The glass fiber cloth is tightly attached to the shape of the battery shell 2. Through the limit frames 3, the pressing frames 4, the reinforcing limiters 13, and the bending pressing edges 6 provided on the pressing frames 4 and the reinforcing limiters 13, the glass fiber cloth can be profiled along the surface of the battery shell 2, and the glass fiber cloth can be positioned and clamped more tightly, so as to ensure that the shape and size of the cut glass fiber cloth match the battery shell 2, and the problem of shaking and displacement during cutting is avoided.

[0050] The limit frames 3 and the pressing frames 4 are designed separately from the reinforcing limiters 13 at both ends to ensure positioning accuracy.

[0051] The end faces of the reinforcing limiters 13, the limit frames 3, and the pressing frames 4 are provided with handles to facilitate turning over and moving.

[0052] Part of the reinforcing limiters 13 is provided with a special-shaped hole, and a cutting sleeve is arranged at the special-shaped hole for cutting the glass fiber at the protruding part of the battery shell 2.

[0053] The lower end of the workbench 1 is provided with a plurality of open tool boxes 105 around the periphery for containing the removed bolts and disassembly tools.

[0054] In a further embodiment of the present scheme, the reinforcing limiters 13 have different width sizes. According to the different parts of the battery shell 2, different pressing and positioning widths are adjusted to ensure the stability of the glass fiber cloth.

The limit frames 3 and the pressing frames 4 both have two hinge points with the workbench 1 to make the installation more stable, and then make the pressing and positioning more stable.

[0057] In a further embodiment of the present application, in order to ensure that the limiting frame 3 and the pressing frame 4 do not interfere with the battery shell 2 on the workbench 1 when they are flipped over. In this embodiment, the workbench 1 is bolted at both ends with a rotating seat 8 corresponding to the hinge point of the limiting frame 3 and the pressing frame 4. Each rotating seat 8 is rotatably installed with a connecting rod 9.
