However, it does not solve the problems of insufficient stability of the mounting block, inconvenience in disassembling the mounting block to install it in the appropriate position, and limited applicability of the device; and the instability of clamping the lead-acid battery, making it inconvenient to remove the clamped lead-acid battery. Utility Model Content

[0004] The purpose of this invention is to provide a welding fixture for lead-acid battery production, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A welding fixture for lead-acid battery production includes a workbench with a mounting groove at the top and a mounting block at the top. The bottom of the mounting block is located inside the mounting groove. Limiting grooves are formed around the mounting groove. A cavity is formed inside the mounting block, and a mounting cavity is formed at the top of the cavity. A fixing mechanism is provided inside the cavity, and a moving mechanism is provided inside the mounting cavity. A fixing cavity is formed at the top of the mounting cavity, and a clamping mechanism is provided inside the fixing cavity.

[0007] Preferably, the fixing mechanism includes a turntable, an arc-shaped block, a movable groove, a limiting block, a T-shaped rod, and a spring.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. This welding fixture for lead-acid battery production, by rotating a first handle, drives a first gear to rotate via a movable rod. The first and second gears mesh, causing the second gear to rotate, which in turn rotates a turntable, moving an arc-shaped block. A spring pushes a T-shaped rod, which in turn moves a limiting block out of its limiting groove, releasing the mounting block from its fixation and allowing it to be installed in the appropriate position. Rotating the first handle again drives the first gear via the movable rod, which in turn drives the turntable, causing the arc-shaped block to rotate and push the T-shaped rod. The T-shaped rod then pushes the limiting block, securing it firmly within the limiting groove and fixing the mounting block in place. This device, utilizing the first handle, movable rod, first gear, second gear, turntable, arc-shaped block, T-shaped rod, spring, limiting block, and limiting groove, improves the stability of the mounting block installation, facilitates disassembly of the mounting block for installation at different locations, and expands the device's applicability.

[0015] 2. This welding fixture for lead-acid battery production places the lead-acid battery on top of the mounting block, positioning it between the clamping blocks. The opposing threads at both ends of the screw cause the movable blocks on either side to move in opposite directions when the screw rotates. A fixed post passes through the movable block, allowing it to slide only along the direction of the fixed post. Rotating the second handle moves the movable block inward via the screw, causing the clamping block to move inward as well, bringing the rubber pad on one side of the clamping block into contact with the lead-acid battery, thus clamping it. When it is necessary to remove the clamped lead-acid battery, rotating the second handle moves the movable block outward via the screw, causing the clamping block to move outward and releasing the lead-acid battery. This device, using the second handle, screw, movable block, fixed post, clamping block, and rubber pad, improves the stability of clamping the lead-acid battery and facilitates its removal.

The clamping mechanism clamps the lead-acid battery, the moving mechanism drives a turntable 8 to rotate, and the fixing mechanism fixes the mounting block 3.

[0024] In this embodiment, preferably, the fixing mechanism includes a turntable 8, an arc-shaped block 9, a movable groove 10, a limiting block 11, a T-shaped rod 12, and a spring 13. The turntable 8 is movably mounted inside the cavity 5 via bearings. Arc-shaped blocks 9 are fixedly mounted around the turntable 8. Movable grooves 10 are formed around the cavity 5. Limiting blocks 11 are movably mounted inside the movable grooves 10. A T-shaped rod 12 is mounted at one end of the limiting block 11, with one end of the T-shaped rod 12 positioned inside the cavity 5. A spring 13 is sleeved on one end of the T-shaped rod 12. One end of the limiting block 11 is positioned inside the limiting groove 4. Through the above-described assembly... The installation block 3 is fixed in place by rotating the arc-shaped block 9 via the turntable 8, which in turn pushes the T-shaped rod 12 via the spring 13. The T-shaped rod 12 then moves the limiting block 11 out of the limiting groove 4, thus removing the fixing of the installation block 3. The installation block 3 is then installed in the appropriate position. The first handle 22 is rotated, which in turn drives the first gear 15 to rotate via the movable rod 14. The second gear 16 then drives the turntable 8 to rotate, causing the arc-shaped block 9 to rotate and push the T-shaped rod 12. The T-shaped rod 12 then pushes the limiting block 11, which is then firmly fixed inside the limiting groove 4.

[0025] In this embodiment, preferably, the moving mechanism includes a movable rod 14, a first gear 15, and a second gear 16. The movable rod 14 is movably mounted on one side of the mounting cavity 6 via a bearing. The first gear 15 is fixedly mounted on one end of the movable rod 14, and the second gear 16 is movably mounted on the bottom end of the mounting cavity 6. The first gear 15 and the second gear 16 mesh with each other. The bottom end of the second gear 16 passes through the cavity 5 and is fixedly connected to the top end of the turntable 8. Through the above device, the movable rod 14 drives the first gear 15 to rotate. The meshing of the first gear 15 and the second gear 16 causes the second gear 16 to rotate, thereby driving the turntable 8 to rotate.

[0026] In this embodiment, preferably, the clamping mechanism includes a screw 17, a movable block 18, a fixed post 19, a clamping block 20, and a rubber pad 21. The screw 17 is movably mounted inside the fixed cavity 7 via bearings. The threads at both ends of the screw 17 are opposite. Movable blocks 18 are sleeved at both ends of the screw 17. A fixed post 19 is fixedly mounted inside the fixed cavity 7, passing through the movable block 18. The top end of the movable block 18 passes through the movable block 18 and is positioned at the top of the mounting block 3. The top end of the movable block 18 is positioned at the top of the mounting block 3. A clamping block 20 is fixedly mounted at the top end of the movable block 18. A rubber pad 21 is fixedly mounted on one side of the clamping block 20. Through the above-described device, the threads at both ends of the screw 17 are opposite, causing the movable blocks 18 on both sides to move in different directions when the screw 17 rotates. The fixed post 19 passes through the movable block 18, so that the movable block 18 can only slide along the direction of the fixed post 19. The screw 17 drives the movable block 18 to move inward, causing the clamping block 20 to move inward, so that the rubber pad 21 on one side of the clamping block 20 contacts the lead-acid battery and clamps the lead-acid battery. When it is necessary to remove the clamped lead-acid battery, the screw 17 drives the movable block 18 to move outward, causing the clamping block 20 to move outward and releasing the lead-acid battery.

[0027] In this embodiment, preferably, one end of the movable rod 14 passes through the mounting block 3 and is disposed on one side of the mounting block 3, and a first handle 22 is fixedly disposed on one end of the movable rod 14. Through the above-mentioned device, the movable rod 14 can be easily rotated through the first handle 22.

[0028] In this embodiment, preferably, one end of the screw 17 passes through the mounting block 3 and is disposed on one side of the mounting block 3, and a second handle 23 is fixedly disposed on one end of the screw 17. Through the above-mentioned device, the screw 17 can be easily rotated by the second handle 23.

[0029] In this embodiment, preferably, sliders 24 are fixedly provided on both sides of the limiting block 11, and sliding grooves 25 are provided on both sides of the movable groove 10. One side of the slider 24 is movably disposed inside the sliding groove 25. Through the above-mentioned device, the limiting block 11 can slide in the movable groove 10.

[0030] In this embodiment, a welding fixture for lead-acid battery production is used such that, when the lead-acid battery is placed on top of the mounting block 3, it is positioned between the clamping blocks 20. The opposing threads at both ends of the screw 17 cause the movable blocks 18 on both sides to move in opposite directions when the screw 17 rotates. A fixing post 19 passes through the movable blocks 18, ensuring that the movable blocks 18 can only slide along the direction of the fixing post 19. Rotating the second handle 23 causes the screw 17 to move the movable blocks 18 inwards, thereby moving the clamping blocks 20 inwards. The rubber pad 21 on one side of the clamping block 20 contacts the lead-acid battery, clamping the lead-acid battery. When it is necessary to remove the clamped lead-acid battery, the second handle 23 is turned, which drives the movable block 18 to move outward through the screw 17, causing the clamping block 20 to move outward and releasing the lead-acid battery. Through the above device, the second handle 23, screw 17, movable block 18, fixed post 19, clamping block 20 and rubber pad 21 improve the stability of clamping the lead-acid battery and facilitate the removal of the clamped lead-acid battery.

[0031] Because the production location may need to be changed during the lead-acid battery production process, it is necessary to disassemble mounting block 3 and install the device in a suitable position to facilitate lead-acid battery production. At this time, turning the first handle 22 causes the movable rod 14 to drive the first gear 15 to rotate. The first gear 15 meshes with the second gear 16, causing the second gear 16 to rotate, which in turn drives the turntable 8 to rotate, moving the arc-shaped block 9. The spring 13 pushes the T-shaped rod 12, causing the T-shaped rod 12 to move the limiting block 11 out of the limiting groove 4, thus releasing the fixation of mounting block 3 and installing it in the appropriate position. Turning the first handle 22... 2. The movable rod 14 drives the first gear 15 to rotate, and the second gear 16 drives the turntable 8 to rotate, causing the arc-shaped block 9 to rotate and push the T-shaped rod 12. The T-shaped rod 12 pushes the limiting block 11, making the limiting block 11 stable inside the limiting groove 4, thus fixing the mounting block 3. Through the above device, the first handle 22, movable rod 14, first gear 15, second gear 16, turntable 8, arc-shaped block 9, T-shaped rod 12, spring 13, limiting block 11 and limiting groove 4, the stability of the mounting block 3 is improved, and the mounting block 3 is easy to disassemble and install in different places, thus improving the applicability of the device.
