Embodiment 2 referring to fig. 1 to 5, the main structure of this embodiment is similar to that of embodiment 1, and some modifications and restrictions are made to the insides of the upper positioning plate 4 and the lower positioning plate 9 on the basis of embodiment 1. The following describes the present embodiment in detail, and the design of the battery clamp of the present embodiment includes several main parts including a base 2, a side plate 3, a top cover 7, a pressing knob 6, a lower positioning plate 9, an upper positioning plate 4, a pressing member 10, a top cover opening 8, a side connection post 11 and a base fixing hole 1. The base 2 is made of a brown yellow flame retardant material, and the stair-shaped design of the edge of the base enables the base not to topple over during working. The side plates 3 are fixed on two sides of the base and are connected with the top cover 7 through side connecting posts 11. The top cover 7 is provided with a plurality of top cover openings 8 which enable hot air to be discharged during operation, so that the battery is kept to work at a proper temperature and is safer during welding. The pressing piece 10 is positioned below the top cover opening 8 and directly contacts with the upper positioning plate 4 to play a role in force borrowing. The hold down 10 may be a resilient object such as a spring to achieve uniform force and promote air circulation.

The pressing knob 6 is designed with an uneven surface to increase friction force during screwing and realize fine control. The battery can be screwed into the side connecting column 11, the top cover 7 is pressed through the rotating action, the firm fixation of the battery is ensured, and the battery is prevented from displacement or falling off in the operation process, so that the operation safety is improved. The side connecting posts 11 penetrate through the top cover fixing holes 5 on the top cover 7, so that the connection between the side plates 3 and the top cover 7 is more stable, the base fixing holes 1 are formed around the base 2, and the fixing holes can be used for fixing the clamp on a workbench or other proper positions. The middle area of the base 2 is hollowed out to reduce weight and facilitate carrying. The side plate 3 extends vertically upwards from the base 2, the top cover 7 is made of a material consistent with the base 2, and is of an overall rectangular structure which is processed by numerical control, one surface of the side plate is milled according to the outline of a battery welding surface so as to fix the battery, and holes are formed according to the positions of the welding points so as to install the pressing piece 10.

It should be noted that, in the battery clamp of this embodiment, the side edge of the upper positioning plate 4 is provided with the reinforced edge grooves 42, which is a significant feature in the design of the upper positioning plate 4, and these edge grooves are presented in a concave form, and are integrated into the structure of the upper positioning plate 4, so that the overall rigidity of the plate is improved, and the upper positioning plate 4 is not easy to deform when bearing pressure. The reinforcing edge groove 42 is designed to enhance the structural strength of the upper positioning plate 4 and to disperse and transmit various forces acting on the plate during operation. During use of the battery clamp, the upper locating plate 4 needs to bear the pressure from the pressing member 10, and the reinforcing edge grooves 42 can effectively disperse the pressure to a wider area, reduce local stress concentration, and prolong the service life of the upper locating plate 4. The upper positioning plate 4 takes into account its positioning accuracy in the jig. The presence of the reinforcing edge groove 42 provides an additional support point for the upper locating plate 4 so that the upper locating plate 4 is accurately placed on the top cover 7. The upper positioning plate 4 is inevitably subjected to repeated load and pressure during long-term use.

It should be noted that the upper positioning plate 4 is provided with reinforcing bars 41 above it, which extend through the entire surface of the upper positioning plate 4, providing additional support and stability to the structure of the clamp. The design of the reinforcing bars 41 in combination with the structural frame in which the cells are placed forms a frame-like shape that significantly enhances the overall strength of the fixture. In particular, the shape of the stiffening strips 41 is constituted by four L-shapes, forming a strong supporting network. The L-shaped structure distributes the compression force applied to the battery, and each L-shaped reinforcing bar intersects the upper positioning plate 4 at a specific angle, forming a stable supporting point, so that the battery can be firmly fixed in the clamp, and any displacement or sliding phenomenon during operation is avoided. This design is critical to maintaining battery stability during welding or other operations and is effective in preventing accidental removal due to shock or external impact. The presence of the reinforcing strip 41 also serves to avoid misalignment problems that may occur when the compression member 10 is subjected to pressure. Because the frame structure of these stiffening strips provides a well-defined guide and support for the hold-down element, it is ensured that it will remain in the correct position when the upper positioning plate 4 is held down. The design not only improves the functionality of the clamp, but also prolongs the service life of the clamp to a certain extent, so that the clamp can keep high-efficiency and stable performance in various working environments. The reinforcing bars 41 of the upper positioning plate 4 enhance stability and durability of the jig by its structural design, and also optimize the fixing effect of the battery.

It should be noted that, in the compacting operation, the compact design of the compacting member 10 is that it can be tightly combined with the reinforcing strip 41 on the upper positioning plate 4. This design allows the compression member 10 to be embedded in the frame formed by the reinforcing bars 41, so that the structural strength of the entire battery clamp is significantly improved. This configuration ensures that the battery is securely and firmly secured in place during the battery welding process even when high temperature and high pressure challenges are encountered. The frame formed by the reinforcing bars 41 provides evenly distributed pressure points, avoiding displacement or damage of the battery due to excessive local pressure, reducing possible short circuits or other safety risks during welding.

It should be noted that the design of the lower positioning plate 9 also represents importance for structural strength and stability. The plurality of stiffening grooves 91 distributed on the plate not only increases the strength of the lower locating plate 9, but also helps to maintain its stability in position during the welding process. The design of these grooves takes into account the heat and vibrations that may occur during welding, ensuring that the lower locating plate 9 is not displaced by these factors, thus ensuring the continuity of the welding process and the welding quality. The locating holes 92 in the lower locating plate 9 are another important feature in the design of the clamp. These locating holes are matched with the size of the battery, so that the fixture can adapt to batteries with different sizes in actual operation, and the locating holes 92 in the upper locating plate 4 and the lower locating plate 9 can be adjusted according to the specific size of the battery. This flexibility ensures that the battery can be accurately positioned and firmly secured in place, and the design of the upper 4 and lower 9 positioning plates also allows for ease of operation, regardless of the size of the battery. The adjustment of the positioning hole 92 and the installation design of the pressing member 10 are simple.

It will be evident to those skilled in the art that the utility model is not limited to the details of the foregoing illustrative embodiments, and that the present utility model may be embodied in other specific forms without departing from the spirit or essential characteristics thereof.
