The limit rod 98 extends upward and out of the sleeve 11, and a conical block 12 is provided on the top of the limit rod 98; the rotating shaft 4 on the support frame 2 passes through the part of the support frame 2 and is connected to a turntable 13, and a slot 14 that cooperates with the conical block 12 is provided on the turntable 13.

[0028] Through the above-mentioned setting structure, when the welder welds the right rear wheel cover of the car, the workpiece is clamped and positioned by the front clamp 6 and the rear clamp 7 set on the workbench 5; during the welding process, the welder stands on the side close to the rear wheel cover sub-assembly, and when welding the D-pillar welding assembly and the C-pillar welding assembly, the conical block 12 is disengaged from the slot 14 by stepping on the foot pedal 19, and then the workbench 5 is manually rotated to a suitable angle, so that the workbench 5 is adjusted to be tilted toward the side of the welder, which makes it easier for the welder to weld the D-pillar welding assembly and the C-pillar welding assembly, thereby improving production and processing efficiency.

[0029] It is worth mentioning that in this embodiment, three slots 14 are provided. By inserting the tapered block 12 into different slots 14, the angle of the workbench 5 can be adjusted. Furthermore, by connecting the ends of the spring 20 to the support frame 2 and the connecting rod respectively, when the foot pedal 19 is not stepped on, the tension of the spring 20 ensures that the tapered block 12 is always stuck in the slot 14, limiting the position of the turntable 13 and preventing the workbench 5 from swinging.

[0030] In this embodiment, the front clamps 6 are provided in three groups. Please refer to Figure 5The front fixture 6 includes a bracket 601, a mounting plate 602, a cylinder 603, and a connecting rod 604. The bottom of the bracket 601 is connected to the workbench 5 via bolts, and the top of the bracket 601 is connected to the mounting plate 602 via bolts.

Leveling bolts 23 are provided on the side plates 22 and are threadedly connected to the side plates 22. The leveling bolts 23 extend downward through the side plates 22 and are fixedly connected to a rectangular plate 24 at their bottom ends. Nuts 25 are movably mounted on the leveling bolts 23 and are located on the upper side of the rectangular plate 24. With this structure, the rectangular plate 24 is supported on the ground, and the bolts 23 are tightened using a tool such as a wrench. Once the bolts 23 are adjusted into position, the nuts 25 are tightened, achieving a convenient and quick leveling of support frame 1 and support frame 2.

[0036] How to use this product:

[0037] During operation, the right rear wheel cover of the car is initially positioned by the positioning pin 710, and then the workpiece is further clamped and positioned by the front clamp 6 and the rear clamp 7; specifically, when the switch controlling the air circuit is turned on, the cylinder 1 603 on the front clamp 6 and the cylinder 2 703 on the rear clamp 7 are both extended, and the connecting rod 1 604 and the connecting rod 2 704 are flipped to press the workpiece, thereby firmly fixing the workpiece on the workbench 5, and the welder can perform welding operations on the rear wheel cover of the car according to the drawings.

[0038] During the welding operation, the welder stands near the side of the rear wheel cover sub-assembly. When welding the D-pillar welding assembly and the C-pillar welding assembly, the workbench 5 is adjusted to be tilted toward the welder's side, so as to facilitate the welder to weld the D-pillar welding assembly and the C-pillar welding assembly; the specific adjustment process is: hold the handle 17 with one hand, and step on the foot pedal 19, and then pass through the pedal 10 and the pull rod 9 in turn, pull down the conical block 12 on the limit rod 98, so that the conical block 12 is disengaged from the slot 14, and then manually flip the handle 17 to rotate the workbench 5 to the appropriate angle, and then release the foot pedal 19. Under the tension of the spring 20, the conical block 12 is re-engaged in the next slot 14, and the turntable 13 is fixed, so that the workpiece is tilted toward the welder's side.

[0039] When welding is complete, the switch controlling the air circuit is closed, and cylinder 1 (603) on the front fixture (6) and cylinder 2 (703) on the rear fixture (7) retract. Connecting rods 1 (604) and 2 (704) flip, opening upper clamps 1 (608) and 2 (708), allowing the welder to remove the welded workpiece. Furthermore, the fixture can be reused repeatedly, improving welder proficiency, processing efficiency, and workpiece quality. Its economical, flexible, precise, stable, and durable weld quality make it a popular choice for welding right rear wheel arches on automobiles.

[0040] The embodiments described above are only preferred embodiments of the present invention and do not limit the scope of implementation of the present invention. Therefore, any equivalent changes or modifications made based on the structure, features and principles described in the patent scope of the present invention should be included in the scope of the patent application of the present invention.
