Detailed Embodiments

[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0023] Embodiment 1: A multi-angle clamping tool for welding automotive parts, refer to Figures 1 - 4As shown in the figure, it includes a base 1 and a bracket 2. Brackets 2 are installed on both the left and right sides of the base 1 by means of bolt connection. A rotating shaft 201 is rotatably arranged on the bracket 2. A workbench 3 is fixedly connected between the inner sides of the two rotating shafts 201 by means of welding. Four support seats 4 are fixedly connected to the middle of the workbench 3. The four support seats 4 are trapezoidally distributed on the workbench 3. Four first mounting brackets 5 are installed on the support seats 4. Two first mounting brackets 5 are located at the rear side of the workbench 3, and the two first mounting brackets 5 are respectively located on the left and right sides of the workbench 3. A support plate 501 is fixedly connected to the side of the first mounting bracket 5 close to the center of the workbench 3 by means of welding. A first cylinder 6 is installed on the side of the first mounting bracket 5 far from the center of the workbench 3 by means of bolt connection. A push plate 7 is rotatably arranged on the telescopic rod of the first cylinder 6. A pressing plate 8 is rotatably arranged on the push plate 7. A rubber pad 801 is installed on the side of the pressing plate 8 close to the workbench 3. When the pressing plate 8 moves downward to clamp the automotive parts, the rubber pad 801 contacts the automotive parts to prevent the pressing plate 8 from pressing and damaging the surface of the automotive parts. The pressing plate 8 is rotatably connected to the first mounting bracket 5. The pressing plate 8 rotates downward to contact the support plate 501. A motor 9 is installed on the left bracket 2 by means of bolt connection. A bidirectional screw rod 10 is connected to the output shaft of the motor 9 through a coupling. The bidirectional screw rod 10 is rotatably connected to the adjacent bracket 2. A guide frame 12 is fixedly connected to the left bracket 2 by means of welding. Arc-shaped clamping blocks 11 that are threadedly arranged at both ends of the bidirectional screw rod 10 and are slidably connected to the guide frame 12. The two arc-shaped clamping blocks 11 slide to clamp the rotating shaft 201. Friction sheets 13 are installed on the sides of the two arc-shaped clamping blocks 11 close to each other. The friction sheets 13 are made of rubber, which can increase the friction between the arc-shaped clamping blocks 11 and the rotating shaft 201 and can stably clamp the rotating shaft 201.

[0024] When welding automotive parts is required, first start the first cylinder 6 and control the telescopic rod of the first cylinder 6 to contract. The telescopic rod of the first cylinder 6 drives the push plate 7 to move downward, causing the push plate 7 to drive the pressing plate 8 to rotate upward with the first mounting bracket 5 as the axis, so that the pressing plate 8 no longer presses against the workbench 3. Subsequently, place the base between the pallet 501 and the support seat 4. The support seat 4 supports the middle part of the base, and the pallet 501 supports the edge of the base. Then, place the automotive parts to be welded in the welding area of the base. Control the telescopic rod of the first cylinder 6 to extend. The telescopic rod of the first cylinder 6 drives the push plate 7 to move upward, and the push plate 7 drives the pressing plate 8 to rotate downward with the first mounting bracket 5 as the axis, so that the pressing plate 8 rotates downward to clamp the automotive parts. Subsequently, rotate the workbench 3 laterally with the rotating shaft 201 as the axis, causing the workbench 3 to drive the support seat 4 and the first mounting bracket 5 to rotate laterally, thereby adjusting the welding angle of the automotive parts, achieving multi-angle adjustment of the welding angle of the automotive parts, enabling the welder to perform comprehensive welding on the automotive parts, avoiding dead angles during welding. Then, start the motor 9 and control the output shaft of the motor 9 to drive the bidirectional screw 10 to rotate forward. The bidirectional screw 10 drives the two arc-shaped clamping blocks 11 to slide towards each other under the guiding action of the guide frame 12, so that the two arc-shaped clamping blocks 11 clamp the rotating shaft 201, thereby preventing the workbench 3 from rotating during the welding process and avoiding the angle of the automotive parts from changing during welding.

[0025] Embodiment 2: On the basis of Embodiment 1, refer to Figure 5 and Figure 6 As shown, it further includes a second mounting bracket 14, a connecting shaft 1401, a second cylinder 15, a connecting block 16, and a connecting plate 17. A second mounting bracket 14 is installed on one side of the base 1. Two connecting shafts 1401 are rotatably arranged on the second mounting bracket 14. A second cylinder 15 is installed between the two connecting shafts 1401. A connecting block 16 is fixedly connected to the telescopic rod of the second cylinder 15. A connecting plate 17 is installed on one side of the workbench 3. The connecting plate 17 is rotatably connected to the connecting block 16.

[0026] When the angle of the workbench 3 needs to be adjusted, start the second cylinder 15, and then control the telescopic rod of the second cylinder 15 to extend. The telescopic rod of the second cylinder 15 drives the connecting plate 17 to move upward through the connecting block 16, and the connecting plate 17 pushes the workbench 3 to rotate, so that there is no need to manually push the workbench 3 for angle adjustment, improving the accuracy of the angle adjustment of the workbench 3 and enhancing the welding accuracy of automotive parts.

[0027] Refer to Figure 1 and Figure 7As shown in the figure, it further includes a support frame 18, a limit frame 19 and a limit screw 21. Two support frames 18 are fixedly connected to one side of the top of the workbench 3. A limit frame 19 is slidably arranged between the two support frames 18. Protective pads 20 are installed on both the left and right sides of the lower part of the limit frame 19. When the limit frame 19 moves downward to clamp the automotive parts, the protective pads 20 come into contact with the automotive parts to prevent the limit frame 19 from scratching the surface of the automotive parts. A limit screw 21 is threadedly arranged on the support frame 18, and the limit screw 21 contacts the limit frame 19.

[0028] When the shape of the automotive parts is relatively special and the pressing plate 8 cannot clamp the automotive parts, place the automotive parts on multiple support seats 4, rotate the two limit screws 21 to make the limit screws 21 no longer press against the limit frame 19, then slide the limit frame 19 downward to make the limit frame 19 clamp the automotive parts, and then rotate the two limit screws 21 in the reverse direction to make the limit screws 21 press against the limit frame 19 again, so as to realize the limitation of irregular parts and improve the application range of the device.

[0029] The above is only the specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention can easily think of changes or substitutions, which should all be covered within the protection scope of the present invention. Therefore, the protection scope of the present invention should be subject to the protection scope of the claims.
