[0002] In the assembly and welding production process of automobile bodies, in order to ensure product quality, improve labor productivity and reduce labor intensity, some tools and devices are often used to clamp and determine the position of the workpiece to complete the assembly and welding work. These tools and devices are collectively referred to as welding fixtures.

[0003] When clamping and welding automotive parts, a lot of heat is generated during the welding process. As the working time increases, the heat cannot be effectively dissipated by the unique material of the clamp itself, which easily leads to heat accumulation on the clamp, causing the clamp material to expand or deform, affecting the stability and accuracy of the clamp, and affecting the quality of the final welded product. Therefore, this application proposes a combined clamp for welding complex automotive parts. Summary of the Invention

[0004] The purpose of this invention is to address the problem in the background art that the heat generated during long-term welding cannot be effectively dissipated by the unique material of the fixture itself, which easily leads to heat accumulation on the fixture, causing the fixture material to expand or deform, affecting the stability and accuracy of the fixture, and affecting the quality of the final welded product.

[0030] Example

[0031] like Figure 1 and Figure 2 As shown, the present invention proposes a combined fixture for welding complex automotive parts, including a support platform 1 and a groove 2 formed on the top of the support platform 1. Two sliders 3 are slidably installed in the groove 2, and a connecting plate 4 is fixedly connected to each slider 3. A support block 5 is fixedly installed on the top of one side of the connecting plate 4, and a support plate 6 is fixedly connected to the top of the other side of the connecting plate 4. The sliding of the sliders 3 can cause the connecting plate 4 to move together with the support block 5 and the support plate 6.

[0032] In addition, a lead screw 14 is rotatably installed in the slide groove 2 and threadedly connected to the slider 3. The inner sides of the two sliders 3 and the lead screw 14 are provided with opposite internal threads. A drive motor 13 is fixedly installed on one side of the support platform 1. The output shaft of the drive motor 13 is fixedly connected to the lead screw 14. When the drive motor 13 is started, the lead screw 14 is rotated, which causes the two sliders 3 to drive the connecting plate 4 to move closer to each other, which facilitates subsequent clamping operations.

[0033] In addition, a rotating shaft 7 is rotatably mounted on the support block 5. One end of the rotating shaft 7 passes through the support plate 6 and is fixedly connected to a turntable 9. A clamping plate frame 10 is fixedly mounted on the turntable 9. A hydraulic rod 11 is fixed on the clamping plate frame 10. A clamping member 12 is connected to the hydraulic rod 11. The two clamping plate frames 10 move closer together by moving the connecting plate 4. The output of the hydraulic rod 11 drives the clamping member 12 to clamp and fix the car parts.

[0034] It is worth noting that a motor cover 8 is fixedly installed on one side of the support block 5. A motor is installed inside the motor cover 8. The output shaft of the motor is fixedly connected to the rotating shaft 7. When the motor is started, the rotating shaft 7 drives the turntable 9 to rotate, so that the clamping plate frame 10 can be rotated and adjusted, and the position and direction of the clamping member 12 can be adjusted and changed, which makes it convenient to fix and clamp some relatively complex automotive parts and improves the ease of use of the device.

[0035] like Figure 1-3 As shown, the device also includes a cooling device, which is installed on the support plate 6 to cool down the heat during fixture welding. The cooling device includes inclined plates 17 fixedly installed on both sides of the support plate 6. An electric telescopic rod 18 is fixedly installed on the inclined plate 17. A fixed plate 19 is fixedly connected to the electric telescopic rod 18. A connector 20 is installed on the fixed plate 19 through a limiting rod. A cooling ring 16 is fixedly connected to the connector 20. An injection pipe 21 is fixedly installed on one side of the cooling ring 16. A rubber sealing plug is provided at the opening of the injection pipe 21. Cooling medium is injected into the cooling ring 16 through the injection pipe 21. The extension and retraction of the electric telescopic rod 18 drives the cooling ring 16 to move back and forth, so that the cooling ring 16 can absorb the heat generated during fixture welding and avoid excessive heat accumulation that could cause material deformation or expansion.

[0036] like Figures 1-5 As shown, the device also includes a cleaning mechanism, which is set on the support platform 1 for cleaning the cooling device. The cleaning mechanism includes a vertical plate 22 fixedly installed on the turntable 9. A connecting groove 23 is fixedly connected to one side of the bottom end of the vertical plate 22. A telescopic plate 24 is slidably installed in the connecting groove 23. A cleaning brush 15 that is slidably connected to the inner wall of the cooling ring 16 is fixedly installed on one side of the telescopic plate 24. The telescopic plate 24 can slide as the electric telescopic rod 18 extends. The rotation of the rotating shaft 7 drives the turntable 9 to rotate, so that the cleaning brush 15 can rotate and rub to clean the residual welding material and grease adhering to the inner wall of the cooling ring 16, so as to avoid affecting the cooling performance of the cooling ring 16.

[0037] It is worth mentioning that a storage tank 25 is fixedly installed at the center of the support platform 1 on one side of the slide 2. A pressure pump 26 is fixedly installed on the top of the storage tank 25. A telescopic hose 27 is provided at one end of the pressure pump 26. A hinge plate 28 is fixedly installed on one side of the storage tank 25. A spray pipe 29 connected to the telescopic hose 27 is hinged on the hinge plate 28. The spray pipe 29 has inclined nozzles on both sides. By rotating the spray pipe 29, the telescopic hose 27 is extended. When the spray pipe 29 is in a horizontal state, the pressure pump 26 draws the cleaning fluid in the storage tank 25 and sprays it onto the inner wall of the cooling ring 16 through the spray pipe 29. This, combined with the cleaning brush 15, improves the cleaning effect.

[0038] The working principle of this embodiment is as follows: Starting the drive motor 13 causes the lead screw 14 to rotate. The two sliders 3 drive the connecting plate 4 to move closer together along the direction of the slide groove 2, causing the two clamping plate frames 10 to move closer together. The output of the hydraulic rod 11 drives the clamping member 12 to clamp and fix the various end faces of the automotive parts to be welded. During welding, the extension and retraction of the electric telescopic rod 18 causes the cooling ring 16 to move back and forth, expanding the cooling range of the cooling ring 16. This allows the cooling ring 16 to cool and absorb heat from the surrounding fixture, preventing excessive heat accumulation in the fixture itself and thus preventing material damage. The expansion or deformation of the material improves the stability and precision of the fixture. After welding, the sliding of the slider 3 drives the two cooling rings 16 to move closer together. At this time, the nozzle 29 rotates to a horizontal position. The pressure pump 26 draws the cleaning fluid from the storage tank 25, allowing the cleaning fluid to enter the nozzle 29 through the telescopic hose 27 and spray it onto the inner wall of the cooling ring 16. At this time, the rotating shaft 7 drives the turntable 9 to rotate, so that the cleaning brush 15 can rotate and rub to clean the inner wall of the cooling ring 16, removing residual welding materials and grease adhering to the surface, and improving the cooling performance of the cooling ring 16.

[0039] The above specific embodiments are merely several optional embodiments of this utility model. Based on the technical solution of this utility model and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
