Description

Technical Field

[0001] The utility model relates to the technical field of automobile bumper welding, in particular to an adjustable automobile bumper welding tool. Background Art

[0002] The car bumper, also known as the plastic bumper, is an important safety device that mainly absorbs and mitigates external impact and protects the car body and passengers. It consists of three parts: the outer plate, the buffer material and the crossbeam. The outer plate and the buffer material are usually made of plastic, while the crossbeam is stamped into a U-shaped groove with cold-rolled thin plates.

[0003] The car bumper is a safety device that absorbs and mitigates external impact and protects the front and rear parts of the car body. During the assembly of the car bumper, multiple parts are welded to the surface of the bumper. However, there are the following problems in the welding process:

[0004] First, although there are some specially customized welding tables for placing car bumpers, after they are placed, both manual welding and machine welding require a large range of movement back and forth to adjust the welding angle, which is not very convenient to operate. In addition, the next product can only be welded after one car bumper is welded and removed, which increases the time for changing materials.

[0005] In addition, after the car bumper is placed on the welding table, there is either no good clamping tool to fix the car bumper, causing it to shake during welding, or a large number of clamping cylinders are used to clamp it, resulting in high processing costs and inconvenient maintenance.

[0024] In this embodiment, after the car bumper is placed in the bumper welding table 6, the servo motor 5 drives the bumper welding table 6 to rotate so as to adjust the welding angle of the car bumper, so that the operator and the machine do not need to move back and forth during welding, thereby reducing the difficulty of operation. At the same time, by driving the top plate 3 to rotate through the driving motor 2, the car bumper to be welded and the car bumper that has been welded can be switched, and a double-station processing mode is adopted, which reduces the time for changing materials and improves the efficiency of welding.

[0025] Example 2, refer to Figures 2 to 3 An adjustable automobile bumper welding tool, an operating table 18 is provided on the top outer wall of the top plate 3, and a symmetrically distributed vertical plate 7 is welded to the top outer wall of the operating table 18, a pressure plate 8 is rotatably connected to the top of the outer wall on one side of the vertical plate 7, and a gear 9 is rotatably connected to the bottom of the outer wall on one side of the vertical plate 7, a pulley group 10 is installed between the gear 9 and the pressure plate 8, a symmetrically distributed double-headed cylinder 12 is fixedly connected to the top outer wall of the operating table 18, and the piston rod of the double-headed cylinder 12 is fixedly connected to a symmetrically distributed rack 11.

[0026] In this embodiment, when the double-headed cylinder 12 controls the rack 11 to move, it can drive the gear 9 to rotate. Since the gear 9 and the pressure plate 8 are transmitted through the pulley group 10, when the gear 9 rotates, the pressure plate 8 can change from being parallel to the vertical plate 7 to being perpendicular to the vertical plate 7, which has a good clamping effect. At the same time, fewer cylinders are used, the structure is simple, the processing cost is reduced, and maintenance is convenient.

[0032] Working principle: first, place the car bumper on the bumper welding table 6, and then control the rack 11 to move and drive the gear 9 to rotate through the double-headed cylinder 12. Since the gear 9 and the pressure plate 8 are driven by the pulley group 10, when the gear 9 rotates, the pressure plate 8 can change from being parallel to the vertical plate 7 to being perpendicular to the vertical plate 7, thereby clamping the car bumper. During welding, the servo motor 5 drives the bumper welding table 6 to rotate to adjust the welding angle of the car bumper and reduce the difficulty of welding. After the car bumper is welded, the top plate 3 is driven to rotate by the driving motor 2, and the car bumper to be welded and the car bumper that has been welded can be switched. The car bumper that has been welded can be dropped along the drop port 16 and the drop chute 17 during the flipping process of the bumper welding table 6.
