[0025] The implementation of the utility model is described in detail below in combination with specific examples.

[0026] In the present embodiment:

[0027] Referring to Figures 1-3 The preferred embodiment is provided by the utility model.

[0028] The automotive battery welding device of this embodiment includes: a base 1. On one side of the upper surface of the base 1, a bracket 2 is fixedly arranged through multiple bolts, which is convenient for disassembly, repair, and maintenance. On one side of the bracket 2, a guide rod 3 is fixedly arranged, and there are two guide rods 3. A stopper is fixedly arranged at one end of the guide rod 3. A guide block 4 is movably sleeved on the outer wall of the guide rod 3, which can guide the guide block 4 and make the guide block 4 move stably horizontally. A connecting block 5 is fixedly arranged on the upper surface of the guide block 4. A first cylinder 6 is fixedly installed on the upper surface of the bracket 2, and the output end of the first cylinder 6 is fixedly connected to the connecting block 5, which can push the guide block 4 to move stably horizontally on the guide rod 3. A fixing frame 7 is fixedly arranged on the bottom surface of the guide block 4, and the fixing frame 7 is arranged in an "L" shape. A second cylinder 8 is fixedly installed on the fixing frame 7. The output end of the second cylinder 8 penetrates through the fixing frame 7 and extends to be connected with a fixing block 9. A welding head 10 is fixedly arranged at the lower end of the fixing block 9, which can push the fixing block 9 to move vertically up and down. A cleaning component 11 for grinding the surface of the workpiece to be welded is arranged on the fixing block 9, and the cleaning component 11 is located on one side of the welding head 10, which can quickly weld the workpiece to be welded after grinding, thereby improving the welding efficiency. Sliding grooves 12 are opened on both sides of the base 1. A clamping component 13 for positioning the workpiece to be welded is slidably arranged inside the sliding grooves 12, which can stably clamp the workpiece to be welded and improve the welding quality.

[0029] Further, as Figure 1 and Figure 2 shown, the cleaning component 11 includes a rotating shaft 111 rotatably arranged on the fixing block 9. A group of connecting rods 112 are fixedly arranged on the outer wall of the rotating shaft 111, and the connecting rods 112 are symmetrically arranged. A grinding disc 113 is rotatably arranged between one ends of the connecting rods 112. A motor 114 is fixedly installed on one side of the connecting rod 112. The output end of the motor 114 penetrates through the connecting rod 112 and extends to be fixedly connected with one end of the grinding disc 113, which can drive the grinding disc 113 to rotate and make the grinding disc 113 grind the welding seam of the automotive battery.

[0030] And, as Figure 1 and Figure 2 shown, the cleaning component 11 further includes a fixing frame 115 fixedly arranged on the outer wall of the rotating shaft 111, and the fixing frame 115 is arranged in a "冂" shape. A through groove 116 is opened on the fixing frame 115, and there are two through grooves 116. A fixing rail frame 117 is slidably arranged inside the through groove 116, and the fixing rail frame 117 is arranged in an arc shape. One end of the fixing rail frame 117 is fixedly connected to the fixing frame 7. A spring 118 is sleeved on the outer wall of the fixing rail frame 117. One end of the spring 118 is fixedly connected to the fixing frame 7, and the other end of the spring 118 is connected to the fixing frame 115, which can apply pressure to the fixing frame 115 to make the grinding disc 113 closely adhere to the welding seam.

[0031] It should be noted that, as Figure 1 and Figure 3As shown, the clamping assembly 13 includes a slider 131 that is slidably disposed inside the slide groove 12, which can stably guide the slider 131. A threaded rod 132 is threadedly sleeved on the slider 131. One end of the threaded rod 132 is rotatably connected to the side of the base 1, which facilitates the adjustment of the horizontal movement of the slider 131. A set of support frames 133 is fixedly connected to the upper surface of the slider 131. The slider 131 is symmetrically arranged and has an "L" shaped structure. A clamping block 134 is fixedly connected to one end of the support frame 133, which can stably position the workpiece to be welded.

[0032] Furthermore, the fixing bracket 7 is fixedly provided with locking blocks 14 on both sides, and the fixing frame 115 is rotatably provided with locking hooks 15 on both sides, which can position the cleaning component 11 for easy storage and use.

[0033] Secondly, the slide groove 12 and the slider 131 are designed with a "T" shape, which makes the connection between the slider 131 and the slide groove 12 more stable.

[0034] Furthermore, the included angle between the connecting rod 112 and the fixed frame 115 is between 90° and 180°, which can drive the grinding disc 113 to rotate stably.

[0035] The working principle of this embodiment is as follows: When welding a car battery, the welding joints of two car batteries are placed together between the clamping blocks 134, and the welding seam of the workpieces to be welded is located directly below the welding head 10. Then, the two threaded rods 132 are manually rotated. The threaded rods 132 are threadedly engaged with the slider 131, causing the slider 131 to move horizontally relative to the other side. The slider 131 drives the clamping blocks 134 to move horizontally relative to the other side through the support frame 133, thus stably clamping the workpieces to be welded placed between the clamping blocks 134.

[0036] The second cylinder 8 is activated, and its output shaft pushes the fixed block 9 to move vertically downward. The fixed block 9 then moves the welding head 10 vertically downward, aligning it with the weld seam. Simultaneously, the fixed block 9, via the rotating shaft 111, moves the connecting rod 112 vertically downward. The connecting rod 112 then moves the grinding disc 113 and the motor 114 vertically downward, bringing the grinding disc 113 into contact with the weld seam. Once the welding head 10 contacts the weld seam, the grinding disc 113 is subjected to pressure, causing it to move the connecting rod 112 upward. The connecting rod 112, via the rotating shaft 111, moves the fixed frame 115 upward. The fixed frame 115 then compresses the spring 118, causing the spring 118 to exert pressure on the fixed frame 115. The fixed frame 115, via the rotating shaft 111, exerts pressure on the connecting rod 112, which in turn exerts pressure on the grinding disc 113, ensuring the grinding disc 113 is tightly pressed against the weld seam.

[0037] The motor 114 is started, which drives the grinding disc 113 to rotate and grind the weld seam. At the same time, the first cylinder 6 is started, which pushes the guide block 4 to move horizontally on the guide rod 3 through the connecting block 5. The guide block 4 drives the welding head 10 and the grinding disc 113 to move horizontally at the same time through the fixing frame 7, the second cylinder 8, and the fixing block 9. This allows for stable and neat grinding and welding of the automotive battery weld seam, ensuring a clean welding area and enabling the welding materials to fuse together better, thereby improving the strength and stability of the weld seam and increasing welding efficiency.

[0038] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
