[0003] In existing technologies, after welding car brackets, welding slag remains on the surface of the fixture, which is difficult to clean. This affects subsequent processing of the car brackets, increases the workload of workers, and reduces production efficiency. Utility Model Content

[0004] The purpose of this utility model is to solve the following shortcomings in the prior art: after welding the car bracket, the welding slag produced in the prior art will remain on the surface of the fixture, which is not easy to clean, will affect the subsequent processing of the car bracket, and will also increase the workload of workers and reduce production efficiency. Therefore, this utility model proposes a tooling fixture for welding auxiliary car bracket assembly.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A tooling fixture for welding auxiliary automotive bracket assembly includes a turntable and two mounting seats, both of which are fixedly connected to the upper surface of the turntable, and a base is rotatably connected to the lower end of the turntable.

[0007] The turntable is equipped with a cleaning component, which includes a fixed plate, a rotating rod, a scraper, an air collection chamber, and a connecting pipe. The two fixed plates are respectively fixedly connected to the mounting base. The rotating rod is rotatably connected to the fixed plate. The two ends of the scraper are respectively threaded to the rotating rod. The air collection chamber is fixedly connected to the scraper. Multiple exhaust ports are fixedly connected to the air collection chamber. One end of the connecting pipe is connected to the air collection chamber.

[0008] Preferably, the cleaning component further includes a rack plate and a piston plate. The turntable has two grooves. The two rack plates are L-shaped and one end of each rack plate is slidably connected in the groove. One end of each piston plate is fixedly connected to the rack plate. One end of the rotating rod is engaged with the piston plate.

[0009] Preferably, a square box is fixedly connected to the turntable, and round holes are respectively opened on the side walls at both ends of the square box. The piston plate is L-shaped, and the end of the piston plate away from the rack plate is slidably connected inside the square box.

[0010] Preferably, the end of the connecting pipe away from the gas collecting chamber is connected to the square box.

[0023] Reference Figures 1-4 A tooling fixture for welding auxiliary automotive bracket assembly includes a turntable 2 and two mounting seats 7, both of which are fixedly connected to the upper surface of the turntable 2.

[0024] The turntable 2 is equipped with a cleaning component, which includes a fixed plate 5, a rotating rod 12, a scraper 6, an air collection chamber 11, and a connecting pipe 14. The two fixed plates 5 are fixedly connected to the mounting base 7, the rotating rod 12 is rotatably connected to the fixed plate 5, the two ends of the scraper 6 are threadedly connected to the rotating rod 12, the lower end of the scraper 6 is slidably connected to the upper surface of the turntable 2, and the air collection chamber 11 is fixedly connected to the scraper 6. When the scraper 6 moves away from the fixed plate 5, it can push impurities to the outside. When the scraper 6 is reset, the path traversed by the scraper 6 is clean. Multiple exhaust ports are fixedly connected to the air collection chamber 11, and one end of the connecting pipe 14 is connected to the air collection chamber 11.

[0025] The cleaning components also include a rack plate 10 and a piston plate 13. Two grooves are provided on the turntable 2. The two rack plates 10 are L-shaped and one end of each rack plate 10 is slidably connected in the groove. One end of each piston plate 13 is fixedly connected to the rack plate 10. One end of the rotating rod 12 is engaged with the piston plate 13. The piston plate 13 is provided with teeth on the part outside the square box 3. When the piston plate 13 moves in the center, it can discharge the gas in the square box 3 through the connecting pipe 14. The square box 3 is fixedly connected to the turntable 2. Circular holes are provided on the side walls at both ends of the square box 3. The piston plate 13 is L-shaped and the end of the piston plate 13 away from the rack plate 10 is slidably connected in the square box 3. The end of the connecting pipe 14 away from the gas collecting chamber 11 is connected to the square box 3.

[0026] The mounting base 7 has a sliding groove, in which two clamping plates 8 are slidably connected. A rotating shaft 9 is rotatably connected to the mounting base 7. Both clamping plates 8 are threadedly connected to the rotating shaft 9. When the rotating shaft 9 rotates, it can drive the two clamping plates 8 to move in the center. A gear 4 is fixedly connected to the end of the rotating shaft 9 away from the mounting base 7. The gear 4 is meshed with the rack plate 10.

[0027] In this utility model, when in use, the two ends of the car bracket are first placed on the mounting base 7 and between the two clamping plates 8. The rack plates 10 are moved by external hydraulic rods. When the two rack plates 10 move away from each other, they can drive the gear 4 and the rotating shaft 9 to rotate. When the rotating shaft 9 rotates, it can drive the two clamping plates 8 to move in the center and clamp and fix the car bracket.

[0028] When the two rack plates 10 move away from each other, they can pull the piston plate 13 to slide inside the square box 3 and discharge the gas inside the square box 3 through the round hole. At the same time, when the piston plate 13 moves, it can drive the rotating rod 12 to rotate. When the rotating rod 12 rotates, it can drive the scraper 6 to move towards the fixed plate 5.

[0029] When the car bracket is welded and needs to be removed, the hydraulic rod pushes the two rack plates 10 to move in the center, and drives the gear 4 and the rotating shaft 9 to rotate in the opposite direction. When the rotating shaft 9 rotates in the opposite direction, it can drive the two clamping plates 8 to move away from each other and no longer clamp the car bracket, so that the car bracket can be removed. At the same time, when the two rack plates 10 move in the center, they can push the piston plate 13. When the two piston plates 13 move in the center, they can squeeze the gas in the square direction 3 into the gas collection chamber 11 through the connecting pipe 14, and discharge it to the upper surface of the chassis 1 through the exhaust port on the gas collection chamber 11. This can work with the scraper 6 to clean the impurities left on the chassis 1.
