[0035] The technical solution of the present application will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present application.

[0036] The present application embodiment discloses a clamp welding device. Figure 1 The welding device includes a bracket 100, a workbench 200, a reinforcement rib feeding assembly 400 and a welding assembly 300.

[0037] The support 100 includes a supporting sub-frame 110 and a connecting sub-frame 120 . The supporting sub-frame 110 is erected on the ground, and the connecting sub-frame 120 is fixedly connected to a side of the supporting sub-frame 110 facing away from the ground.

[0038] The workbench 200 is mounted on the supporting subframe 110 , and the connecting subframe 120 is spaced apart from the workbench 200 .

[0039] The welding assembly 300 is used to weld the reinforcing rib and the clamp together. In this embodiment, two groups of welding assemblies 300 are provided. In other embodiments, the welding assembly 300 can also be provided in one group.

[0040] The two groups of welding assemblies 300 are respectively arranged on both sides of the clamp, and the two groups of welding assemblies 300 both include a mounting seat 310 , a connecting seat 320 , a contoured member 330 and a welding gun 340 .

[0041] A plurality of first slideways 121 are fixedly connected to the side of the connecting subframe 120 close to the workbench 200. The plurality of first slideways 121 are sequentially arranged in a direction close to the ground, and the first slideways 121 are extended along the length direction of the clamp. In this embodiment, two first slideways 121 are arranged. The mounting seats 310 of the two groups of welding assemblies 300 are fixedly connected with first sliders 311. The first sliders 311 are provided with first slide grooves adapted to the shape of the first slideways 121, so that the mounting seats 310 of the two groups of welding assemblies 300 can move in a direction close to or away from each other. The connecting subframe 120 is provided with a driving assembly 500 for driving the mounting seats 310 of the two groups of welding assemblies 300 to move.

[0042] The driving assembly 500 includes a driving motor 510 and a driving screw 520. The driving screw 520 is a bidirectional screw and is located between the two first slideways 121. Both ends of the driving screw 520 are rotatably mounted on the connecting subframe 120. The mounting seats 310 of the two welding assemblies 300 are both threadedly connected to the driving screw 520, and the threads at the connection positions of the mounting seats 310 of the two welding assemblies 300 and the driving screw 520 are reverse threads. The body of the driving motor 510 is fixedly connected to the connecting subframe 120, and the output shaft of the driving motor 510 is coaxially fixedly connected to the driving screw 520.

[0043] The drive motor 510 is started to drive the drive screw 520 to rotate, thereby driving the mounting bases 310 of the two sets of welding assemblies 300 to move toward or away from each other, so that the welding assemblies 300 can be suitable for the installation of reinforcing ribs of clamps of different sizes.

[0044] The installation methods of the two groups of welding assemblies 300 are the same. The welding assemblies 300 of the present application are described below by taking one of the groups of welding assemblies 300 as an example.

[0045] The mounting seat 310 is fixedly connected with a second slideway 312 arranged in a direction close to or away from the supporting subframe 110, and the connecting seat 320 is fixedly connected with a second slider 321, and the second slider 321 is provided with a second slide groove matching the shape of the second slideway 312, so that the connecting seat 320 can slide in a direction close to or away from the supporting subframe 110. In order to prevent the connecting seat 320 from sliding excessively, a bolt is threadedly connected to the second slideway 312.

[0046] The profiling member 330 is fixedly connected to the connecting seat 320 by bolts, and the profiling member 330 can contact the side of the hoop. In this embodiment, the profiling member 330 is rod-shaped. In order to reduce the wear of the profiling member 330 when the profiling member 330 and the hoop are relatively displaced, a ball is rolled and connected to one side of the profiling member 330 close to the hoop.

[0047] Reference Figure 1 and Figure 2 The welding gun 340 includes a welding gun body 341, a connecting rod 342 and a connecting seat 343. The welding gun body 341 is connected to the connecting rod 342 through the connecting seat 343. The connecting rod 342 is rotatably connected to the connecting seat 320. A rotating assembly 600 for driving the connecting rod 342 to rotate is provided on the connecting seat 320.

[0048] The rotating assembly 600 includes a rotating rack 610 and a rotating gear 620. The rotating rack 610 is slidingly connected to the connecting seat 320, and the rotating gear 620 is coaxially fixedly connected to the connecting rod 342. The rotating rack 610 is meshed with the rotating gear 620 so that the rotating rack 610 can drive the rotating gear 620 to rotate.

[0049] A sliding member for driving the rotating rack 610 to slide is provided on the connecting seat 320. In this embodiment, the sliding member is a rotating cylinder 611. The cylinder body of the rotating cylinder 611 is fixedly connected to the connecting seat 320, and the piston rod of the rotating cylinder 611 is fixedly connected to the rotating rack 610 to drive the rotating rack 610 to move.

[0050] In order to facilitate the staff to adjust the rotation angle of the rotating gear 620, a positioning assembly 700 for adjusting the rotation angle of the rotating gear 620 is provided on the connecting seat 320. Specifically, the positioning assembly 700 includes a fixing member 710 and a positioning member 720. In this embodiment, the fixing member 710 is a fixing block, and the fixing member is fixedly connected to the connecting seat 320. The positioning member 720 is a positioning bolt, and the positioning member 720 is threadedly connected to the fixing member 710 and is located on the moving track of the rotating rack 610, so that the positioning assembly 700 can adjust the rotation angle of the rotating gear 620 by adjusting the sliding end point of the rotating rack 610.

[0051] In order to prevent the profiling member 330 from interfering with the sliding of the rotating rack 610 , the end of the profiling member 330 close to the workbench 200 is bent toward the welding gun body 341 so that the profiling member 330 makes way for the sliding of the rotating rack 610 .

[0052] In order to improve the degree of automation of the operation of the welding device, a connecting cylinder 313 for driving the connecting seat 320 to slide is provided on the mounting seat 310, the cylinder body of the connecting cylinder 313 is fixedly connected to the mounting seat 310, and the piston rod of the connecting cylinder 313 is fixedly connected to the connecting seat 320. The setting of the connecting cylinder 313 makes it difficult for the welding gun 340 to interfere with the movement of the clamp, and on the other hand, the sliding margin of the piston rod of the connecting cylinder 313 itself can allow the profiling member 330 to have enough sliding distance so that the profiling member 330 can drive the welding gun 340 to move along with the shape of the clamp.

[0053] The workbench 200 is slidably connected to the supporting subframe 110. In this embodiment, a slide rail 111 is fixedly connected to the supporting subframe 110, and the slide rail 111 is arranged along the length direction of the connecting subframe 120. A sliding block that cooperates with the slide rail 111 is fixedly connected to one side of the workbench 200 close to the supporting subframe 110, so that the workbench 200 can slide along the slide rail 111. A moving assembly 800 for driving the workbench 200 to move is arranged on the supporting subframe 110.

[0054] The moving assembly 800 includes a moving cylinder 810, a cylinder body of the moving cylinder 810 is fixedly connected to the supporting subframe 110, and a piston rod of the moving cylinder 810 is fixedly connected to the workbench 200 via a connecting plate. In other embodiments, the moving cylinder 810 can be replaced by other structures that can realize linear motion.

[0055] The moving cylinder 810 is started so that the piston rod of the moving cylinder 810 drives the connecting plate to move the workbench 200 .

[0056] The reinforcing rib feeding assembly 400 includes a feeding member 410 and a driving member 420. The feeding member 410 is provided with a receiving groove 411 for receiving the reinforcing rib, so that the staff can insert the reinforcing rib into the receiving groove 411 so that the feeding member 410 can clamp the reinforcing rib. In this embodiment, the driving member 420 is a driving cylinder. In other embodiments, the driving member 420 can adopt a structure that can realize linear motion. The cylinder body of the driving cylinder is fixedly connected to the workbench 200, and the piston rod of the driving cylinder is fixedly connected to the feeding member 410.

[0057] Reference Figure 1 and Figure 3 A stopper 412 is fixedly connected to the side of the loading piece 410 away from the piston rod of the driving cylinder. The stopper 412 is located in the receiving groove 411, and when the loading piece 410 clamps the reinforcing rib, the stopper 412 can contact the side of the reinforcing rib, so that the reinforcing rib is not easy to fall out of the receiving groove 411.

[0058] In order to facilitate the staff to install the clamp on the workbench 200, a limit block 210 that is plugged into the installation hole is fixedly connected to the workbench 200 by bolts.

[0059] In order to improve the safety of the welding device during operation, a protective cover is fixedly connected to the bracket 100, and the protective cover is arranged outside the two groups of welding components.

[0060] The implementation principle of a clamp welding device in the embodiment of the present application is as follows: the staff places the clamp on the workbench 200 and makes the mounting hole of the clamp engage with the corresponding limit block 210, starts the driving member 420 so that the driving member 420 drives the feeding member 410 to move the reinforcing rib to a position that matches the clamp, then starts the driving motor 510 to move the welding gun 340 assembly to a suitable position, and then starts the connecting cylinder 313 to move the welding gun body 341 to a suitable position and the profiling member 330 to a position that contacts the clamp, and then starts the welding gun body 341 so that the welding gun body 341 welds one side of the clamp and the reinforcing rib;

[0061] When welding on one side of the reinforcement rib is completed, start the connecting cylinder 313 to move the welding gun body 341 and the profiling member 330 away from the workbench 200, and then start the rotating cylinder 611 to drive the welding gun 340 to rotate, so that the welding gun body 341 can weld the other side of the reinforcement rib.

[0062] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
