[0002] With the rapid development of the automotive industry, the pace of vehicle model updates and replacements is accelerating, and vehicle models are changing faster and faster. At the same time, there are more and more vehicle styles, which will inevitably lead to some welding processes that are difficult to weld and cannot be met by ordinary welding guns, especially the welding points on the exterior surfaces of automotive parts.
[0003] Currently, the main forms of resistance welding in automotive sheet metal are spot welding machines and automated spot welding robots. These welding methods cover most of the process implementation of sheet metal parts. However, for some complex parts such as door covers and side panels with high requirements for weld point welding, conventional welding methods have technical problems such as weak protection of parts with high requirements for weld point welding, narrow space of positioning fixtures, and difficulty in ensuring the smoothness of the surface.

[0025] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.
[0026] Please see Figure 1-4 As shown, this utility model is a novel automotive sheet metal puppet welding equipment, including a fixture body 1, a first positioning frame 3 disposed on the outer side of the top of the fixture body 1, and a conveyor belt mechanism 2 disposed on one side of the top of the fixture body 1, and further including:
[0027] The second positioning frame 17 is located at the top of the fixture body 1 near the edge. Limiting plates 11 are provided on both sides of the top of the fixture body 1, and these plates are parallel to each other. During welding, the front door part to be welded is conveyed to the welding position via the conveyor belt mechanism 2. Personnel place the part in the positioning position, and the limiting plates 11 constrain the front door part. A clamping and fixing mechanism is provided on the top of the second positioning frame 17. This mechanism includes a clamping cylinder 16, a lifting seat 10, a second hinge seat 15, an upper clamping seat 6, a lower clamping seat 18, and a status indicator light 19. The clamping cylinder 16 is located on the top outer side of the second positioning frame 17, and the lower clamping seat 18 is located on the inner side of the top of the second positioning frame 17. 8. A lifting seat 10 is provided at the top of the clamping cylinder 16. A second hinge seat 15 is movably hinged to the top of the lifting seat 10. An upper clamping seat 6 is provided at the top of the second hinge seat 15. One side of the bottom of the second hinge seat 15 is hinged to the top of the second positioning frame 17. The upper clamping seat 6 and the lower clamping seat 18 correspond one to one. After the front door part is positioned and placed, the clamping cylinder 16 is started by controlling the operating panel to lift the lifting seat 10 and then lift the outer end of the second hinge seat 15. At the same time, the upper clamping seat 6 and the lower clamping seat 18 are lowered to clamp and fix the edge of the car front door part, so that it is stable on the clamping body 1. A status indicator light 19 is provided on one side of the top of the upper clamping seat 6. After the front door part is clamped, the status indicator light 19 lights up to sense the clamping status.
[0028] As a further implementation of this embodiment, such as Figure 1-4 As shown, the puppet welding clamping cylinder 9 is hinged to the top of the outside of the first positioning frame 3. The top of the puppet welding clamping cylinder 9 is movably hinged to the first hinge seat 12. The top of the first hinge seat 12 is provided with the puppet welding upper electrode 5. One side of the bottom of the first hinge seat 12 is movably hinged to the top of the first positioning frame 3. One side of the top of the first positioning frame 3 is provided with the puppet welding lower electrode 14. After the front door part is fixed, the puppet welding clamping cylinder 9 is activated to lift the outer end of the first hinge seat 12, so that the puppet welding upper electrode 5 provided on the top side of it descends and cooperates with the puppet welding lower electrode 14 to clamp and weld the welding point on the front door part to complete the welding task. The two sides of the puppet welding upper electrode 5 are connected to the through holes and are provided with insulating bushings 13. The insulating bushings 13 are used to ensure the effective transmission of current in the secondary circuit and avoid current shunting.
[0029] When the front door part to be welded is clamped and fixed on the fixture body 1 by the clamping and fixing mechanism, the puppet welding clamping cylinder 9, which is hinged to the top of the outside of the first positioning frame 3, is activated. The puppet welding clamping cylinder 9 drives the first hinge seat 12, which is hinged to the top of the first hinge seat 12, to rise. This causes the first hinge seat 12 to rotate inward at the hinge point with the top of the first positioning frame 3, thereby driving the puppet welding upper electrode 5 set on the top of the first hinge seat 12 to descend. The puppet welding upper electrode 5 descends and cooperates with the puppet welding lower electrode 14, which is fixed on the inner side of the top of the first positioning frame 3, to clamp and weld the weld point on the front door part.
[0030] As a further implementation of this embodiment, such as Figure 1 and Figure 2 As shown, the transfer stabilization assembly is located at the four corners of the bottom of the fixture body 1. The transfer stabilization assembly includes a moving wheel 4, a lifting cylinder 7, and a stabilizing base 8. The moving wheel 4 is located at the four corners of the bottom of the fixture body 1. The moving wheel 4 can flexibly move the equipment for convenient transfer and adjustment of the positioning welding position. The lifting cylinder 7 is located on both sides of the bottom of the fixture body 1. The stabilizing base 8 is located at the bottom of the lifting cylinder 7. The lifting cylinder 7 drives the stabilizing base 8 to descend and touch the ground to stabilize the equipment and ensure stable welding work.
[0031] When in use, the lifting cylinders 7 set on both sides of the bottom of the fixture body 1 lift the stable base 8 set at the bottom end, so that the bottom end of the stable base 8 is lifted off the ground. The moving wheels 4 set at the four corners of the bottom end of the fixture body 1 can flexibly move the equipment. After the equipment is moved to the designated welding station, the lifting cylinders 7 are activated to push the stable base 8 down to touch the ground, which restricts the free rolling of the moving wheels 4 and thus stabilizes the equipment.
[0032] Working principle: When using the automotive sheet metal puppet welding equipment, the equipment is moved to the designated welding station by the moving wheels 4. Then, the lifting cylinder 7 is activated to push the stabilizing base 8 down to the ground to stabilize the equipment. During welding, the front door part to be welded is conveyed to the puppet welding position by the conveyor belt mechanism 2. The operator places the part in the positioning position and limits the front door part by the limit plate 11. Then, the technician controls the clamping cylinder 16 to lift the lifting seat 10 through the operating panel, thereby lifting the outer end of the second hinge seat 15, while lowering the... The upper clamp 6 and the lower clamp 18 work together to clamp and fix the edge of the car front door part. The status indicator light 19 illuminates to indicate the clamping status. The puppet welding clamping cylinder 9 is activated to drive the first hinge seat 12 to rise. The first hinge seat 12 rotates inward with the hinge point at the top of the first positioning frame 3, causing the upper puppet welding electrode 5 to descend and work with the lower puppet welding electrode 14 to clamp and weld the weld points on the front door part. The insulating bushing 13 ensures the effective transmission of current in the secondary circuit and avoids current shunting, thus completing the welding task of the weld points on the exterior surface of the front door part.
[0033] The above are merely preferred embodiments of the present utility model and do not limit the present utility model. Any modifications, equivalent substitutions, or improvements made to the technical solutions described in the foregoing embodiments, or to some of the technical features, shall fall within the protection scope of the present utility model.
