Description

Technical Field

[0001] This utility model relates to the field of cover plate welding fixture technology, specifically a welding fixture for a new energy vehicle battery cover plate. Background Technology

[0002] The battery cover and battery are usually connected by welding. During welding, the cover and battery need to be secured. To secure the battery, place it in a slot that can limit its position, and then place the cover on top of the battery.

[0003] During welding, to prevent the cover from lifting, it needs to be pressed onto the battery before welding. To prevent the object pressing the cover from obstructing the welding process, several grooves are made on the object pressing the cover. During welding, spot welding is first performed through these grooves. Then, after the pressing plate of the cover is moved away, a second welding is performed. This welding method requires two welding operations, which makes the welding efficiency low. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model proposes a welding fixture for battery covers of new energy vehicles, which can complete the welding in one go.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a welding fixture for a battery cover of a new energy vehicle, including a limiting seat, a battery limiting groove on the upper surface of the limiting seat, multiple pressure plates on both sides of the battery limiting groove, and multiple electromagnets below the pressure plates. A guide groove is provided on the surface of the limiting seat below each pressure plate, and a guide component is provided in the guide groove to allow the pressure plate to slide along the axis of the guide groove.

[0006] Preferably, the guiding assembly includes a slide tube that is slidably connected to the inner wall of the guiding groove, and one end of the slide tube is fixedly connected to the pressure plate. A compression spring is provided inside the slide tube, and one end of the compression spring is fixedly connected to a limit post. The limit post is slidably connected to the inner wall of the slide tube, and one end of the limit post is fixedly connected to a limit seat.

[0007] Preferably, a top block is slidably connected to the inner wall of the battery limiting groove, and a push rod is fixedly connected to the lower surface of the top block, with the lower end of the push rod fixedly connected to the limiting seat.

[0008] Preferably, the upper surface of the top block has a groove.

[0009] Preferably, the side wall of the limiting seat is provided with a clearance groove, and the clearance groove is matched with the slide tube.

[0010] Preferably, the side wall of the limiting seat is fixedly connected to an installation connecting block, and the upper surface of the installation connecting block is provided with an installation through hole.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] This invention utilizes multiple pressure plates in conjunction with electromagnets. During use, the battery is placed in the battery positioning slot, and then the electromagnet is activated, attracting the pressure plates downwards. The pressure plates then press against the battery cover, allowing welding to proceed. When the welding position reaches one side of the pressure plate, the electromagnet is de-energized, causing the pressure plates to reset. This ensures that the pressure plates automatically avoid the area being pressed down, allowing welding to be completed in one pass, thus improving welding efficiency. Attached Figure Description

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0019] Please see Figures 1 to 4 A welding fixture for a battery cover of a new energy vehicle includes a limiting seat 1. A battery limiting groove 2 is formed on the upper surface of the limiting seat 1. Multiple pressure plates 3 are provided on both sides of the battery limiting groove 2. Multiple electromagnets 4 are provided below the pressure plates 3. A guide groove 5 is formed on the surface of the limiting seat 1 located below each pressure plate 3. A guide component is provided in the guide groove 5 to allow the pressure plate 3 to slide along the axis of the guide groove 5.

[0020] As can be seen from the above structure, by setting multiple pressure plates 3 and electromagnets 4 in conjunction, when in use, the battery is placed in the battery limiting groove 2, and then the electromagnet 4 is activated, causing the electromagnet 4 to attract the pressure plate 3 to move down, thereby causing the pressure plate 3 to press against the battery cover. Welding can then be performed. When the welding position reaches one side of the pressure plate 3, the electromagnet 4 is de-energized, causing the pressure plate 3 to reset. In this way, when welding reaches the position pressed by the pressure plate 3, the pressure plate 3 will move aside on its own, and welding can be completed in one go, thereby improving welding efficiency.

[0021] See Figure 2 , Figure 3 and Figure 4 The guiding assembly includes a slide tube 6 that is slidably connected to the inner wall of the guide groove 5, and one end of the slide tube 6 is fixedly connected to the pressure plate 3. A compression spring 7 is installed inside the slide tube 6, and one end of the compression spring 7 is fixedly connected to a limit post 8. The limit post 8 is slidably connected to the inner wall of the slide tube 6, and one end of the limit post 8 is fixedly connected to a limit seat 1. By using the slide tube 6 and the compression spring 7 in conjunction, when the electromagnet 4 is de-energized, the compression spring 7 can push the pressure plate 3 to reset. It should be noted that the length of the guide groove 5 is greater than the length of the compression spring 7 after the pressure is released, to ensure that the slide tube 6 will not detach from the limit post 8.

[0022] See Figure 2 A top block 9 is slidably connected to the inner wall of the battery limiting groove 2, and a push rod 10 is fixedly connected to the lower surface of the top block 9. The lower end of the push rod 10 is fixedly connected to the limiting seat 1. By setting the top block 9 and the push rod 10 to work together, after the battery is welded, the push rod 10 can be activated, which will cause the push rod 10 to retract from the computer top block 9. The moving top block 9 will drive the battery to move upward, so that the battery will be removed from the battery limiting groove 2.

[0023] See Figure 2 The top block 9 has a groove 11 on its upper surface. By setting the groove 11, impurities that fall on the top block 9 can be cleaned into the groove 11, so as to avoid the impurities affecting the height of the battery.

[0024] See Figure 2 and Figure 3 The side wall of the limiting seat 1 is provided with a relief groove 12, and the relief groove 12 is matched with the slide tube 6; by providing the relief groove 12, the slide tube 6 can be accommodated.

[0025] See Figure 1 and Figure 2 The side wall of the limiting seat 1 is fixedly connected to the mounting connecting block 13, and the upper surface of the mounting connecting block 13 is provided with a mounting through hole; by setting the mounting connecting block 13 and the mounting through hole, it can be used to fix the limiting seat 1.

[0026] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
