When repairing, two sheet metal parts need to be welded. In order to accurately weld the two sheet metal parts, people generally position the two sheet metal parts and then weld them.

[0003] After retrieval, the patent document with the publication number CN119115364A discloses a positioning welding device for sheet metal parts of new energy vehicles, which includes a welding table. A support plate is fixedly connected to the middle of the upper end surface of the welding table. Two first sliding rods are slidably connected to the support plate.

Detailed implementation manners

[0023] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0024] Please refer to Figures 1 to 8As shown in the figure, a welding device for new energy vehicles includes a workbench 1. Two first clamping plates 2 are slidably installed on the top of the workbench 1. A top plate 4 is fixedly installed on the top of the workbench 1. A sliding plate 42 is slidably installed at the bottom of the top plate 4. Four third electric telescopic rods 45 are fixedly installed at the bottom of the sliding plate 42. It also includes a slag removal mechanism for cleaning the welding slag generated during welding. The slag removal mechanism includes a mounting plate 46 which is fixedly installed at the output ends of the four third electric telescopic rods 45. A sixth groove 462 is formed at the bottom of the mounting plate 46. A slider 4623 is slidably installed on the inner surface of the sixth groove 462. A second threaded rod 4621 is rotatably installed on the inner surface of the sixth groove 462. The second threaded rod 4621 is threadedly connected to the slider 4623. One end of the second threaded rod 4621 is fixedly connected to a fourth motor 4622 which is fixedly installed on one side of the mounting plate 46. Two fourth electric telescopic rods 4624 are fixedly installed at the bottom of the slider 4623. The output end of one of the fourth electric telescopic rods 4624 is fixedly connected to a welding torch 4625. The output end of the other fourth electric telescopic rod 4624 is fixedly connected to a fifth motor 4626. The output shaft of the fifth motor 4626 is fixedly connected to a grinding wheel 4627.

[0025] After welding the automotive sheet metal parts, it is necessary to remove the welding slag generated during welding to accurately observe the welding situation.

[0026] When the present invention is in use, first place two sheet metal parts on the top of the workbench 1, then move two first clamping plates 2 closer to clamp the sheet metal parts. At this time, the output shaft of the fourth motor 4622 drives the second threaded rod 4621 to rotate. The second threaded rod 4621 can drive the slider 4623 to slide on the inner surface of the sixth groove 462. The second threaded rod 4621 drives the slider 4623 to move the welding torch 4625 to the place where the two sheet metal parts are in contact. At this time, the fourth electric telescopic rod 4624 drives the welding torch 4625 to descend and weld the sheet metal parts. After welding is completed, the welding torch 4625 moves upward. Then the other fourth electric telescopic rod 4624 drives the fifth motor 4626 to move downward. Then adjust the height of the grinding wheel 4627 according to the height of the welding slag. The output shaft of the fifth motor 4626 drives the grinding wheel 4627 to rotate, and the grinding wheel 4627 cleans the welding slag generated by welding the sheet metal parts.

[0027] Further, as Figure 2 shown, four third grooves 13 are formed on the top of the workbench 1. Two first clamping plates 2 are respectively slidably installed on the inner surfaces of the four third grooves 13. Two connecting rods 21 are rotatably installed at the bottom of the first clamping plate 2. The bottoms of the four connecting rods 21 are jointly rotatably connected to a cross plate 22. Two first electric telescopic rods 23 are fixedly installed at the bottom of the cross plate 22, and the bottoms of the two first electric telescopic rods 23 are fixedly installed on the inner wall of the workbench 1. Two first clamping plates 2 are jointly slidably connected to two first sliding rods 211, and the two first sliding rods 211 are fixedly installed on the inner wall of the workbench 1.

[0028] When the present invention is in use, when it is necessary to fix the sheet metal parts, first place the two sheet metal parts on the top of the workbench 1, and then shorten the two first electric telescopic rods 23. The first electric telescopic rods 23 pull the cross plate 22 to move downward. The cross plate 22 simultaneously drives the four connecting rods 21 to rotate and move downward. At the same time, the four connecting rods 21 respectively rotate at the bottom of the two first clamping plates 2. Under the limitation of the two first sliding rods 211, the two first clamping plates 2 slide on the inner surface of the two third grooves 13 and approach each other, which can clamp the sheet metal parts.

[0029] Furthermore, as Figure 4 shown, a second groove 12 is formed in the top of the workbench 1. A first bidirectional threaded rod 25 is rotatably installed on the inner surface of the second groove 12. Two second clamping plates 24 are slidably installed on the inner surface of the second groove 12. The two second clamping plates 24 are both threadedly connected to the first bidirectional threaded rod 25. One end of the first bidirectional threaded rod 25 is fixedly connected to a first motor 27. The first motor 27 is fixedly installed on one side of the workbench 1. A second sliding rod 26 is jointly slidably connected to the opposite surfaces of the two second clamping plates 24. The second sliding rod 26 is fixedly installed on the inner surface of the second groove 12.

[0030] When the present invention is in use, after clamping the sheet metal parts by the two first clamping plates 2, it is also necessary to align the welding positions of the two sheet metal parts. During use, the output shaft of the first motor 27 drives the first bidirectional threaded rod 25 to rotate. The first bidirectional threaded rod 25 can drive the two second clamping plates 24 to slide on the inner surface of the second groove 12 and approach each other under the action of the second sliding rod 26, so that the welding joints of the two sheet metal parts to be welded are aligned.

[0031] Furthermore, as Figure 3 shown, four first grooves 11 are formed in the top of the workbench 1. A second electric telescopic rod 3 is fixedly installed on the inner surface of the first groove 11. The output end of the second electric telescopic rod 3 is fixedly connected to a top piece 31. The top piece 31 is slidably installed on the inner surface of the first groove 11.

[0032] When the present invention is in use, after welding is completed, the sheet metal part needs to be taken off from the top of the workbench 1. When welding, the sheet metal part is placed on the top of the workbench 1. Therefore, the sheet metal part needs to be lifted to facilitate taking it out. By extending the output end of the second electric telescopic rod 3, the top piece 31 can slide on the inner surface of the first groove 11. Then, the top piece 31 pops out of the first groove 11 to separate the sheet metal part from the workbench 1. The four top pieces 31 moving upward simultaneously can keep the sheet metal part stable.

[0033] Furthermore, as Figure 5 shown, a fourth groove 41 is formed at the bottom of the top plate 4, the sliding plate 42 is slidably installed on the inner surface of the fourth groove 41, and two fifth grooves 461 are formed at the bottom of the mounting plate 46; The second bidirectional threaded rod 4612 is rotatably installed on the inner surface of the fifth groove 461. Two third clamping plates 4611 are slidably installed on the inner surface of the two fifth grooves 461 together. The second bidirectional threaded rod 4612 is threadedly connected to the third clamping plate 4611. One end of one of the second bidirectional threaded rods 4612 is fixedly connected to a third motor 4613, and the third motor 4613 is fixedly installed on one side of the mounting plate 46; Gears 4614 are fixedly installed at one ends of the two second bidirectional threaded rods 4612, and the two gears 4614 mesh with each other. A ventilation pipe 47 is fixedly connected to the outer surface of the fifth motor 4626. The ventilation pipe 47 is connected to a collection box 471 in a penetrating manner. A filter plate 472 is fixedly installed in the inner cavity of the collection box 471, and a blower 473 is fixedly installed on one side of the collection box 471.

[0034] When the present invention is in use, the output shaft of the second motor 44 drives the first threaded rod 43 to rotate. The first threaded rod 43 can drive the sliding plate 42 to slide on the inner surface of the fourth groove 41. At the same time, the sliding plate 42 can drive the mounting plate 46 to slide at the bottom of the top plate 4 through the four third electric telescopic rods 45. When it is necessary to clamp the welded sheet metal part, the output shaft of the third motor 4613 drives one of the second bidirectional threaded rods 4612 to rotate. Through the two gears 4614, the other second bidirectional threaded rod 4612 can also start to rotate. The two second bidirectional threaded rods 4612 synchronously drive the two third clamping plates 4611 to approach each other along the inner surface of the fifth groove 461 to clamp the sheet metal part. Further, by driving the sliding plate 42 to slide through the second motor 44 driving the first threaded rod 43, the sheet metal part clamped by the two third clamping plates 4611 can be transferred. When the grinding wheel 4627 rotates to clean the welding slag, the welding slag will enter the collection box 471 through the ventilation pipe 47 under the action of the blower 473. The welding slag remains on one side of the filter plate 472, and the blower 473 is on the other side of the filter plate 472.

[0035] Furthermore, as Figure 8As shown in the figure, two conveyor rollers 5 are rotatably installed on one side of the workbench 1. The two conveyor rollers 5 are driven by a conveyor belt 51. One side of the top plate 4 is fixedly installed with a support frame 53. One end of one of the conveyor rollers 5 is fixedly connected to a sixth motor 52, and the sixth motor 52 is fixedly installed on one side of the support frame 53; Two inclined plates 54 are fixedly connected to the outer surfaces of the support frame 53 and the workbench 1. The two inclined plates 54 are slidably installed on the outer surface of the conveyor belt 51. A sensor 55 is fixedly installed in the inner cavity of the support frame 53.

[0036] When the present invention is in use, the first threaded rod 43 is used to drive the sliding plate 42 to transfer two sheet metal parts to the top of the conveyor belt 51. At this time, the sensor 55 will detect the welded joints of the sheet metal parts, and the sensor 55 can also control the rotation direction of the output shaft of the sixth motor 52 according to different detection results. For the sheet metal parts with qualified welding, the output shaft of the sixth motor 52 drives the conveyor roller 5 to rotate, and the conveyor roller 5 can drive the conveyor belt 51 to rotate. The sheet metal parts are transferred to one side by the conveyor belt 51, and the sheet metal parts slide down along the inclined plate 54 on that side. For the sheet metal parts with unqualified welding, the sixth motor 52 rotates in the reverse direction, and the sheet metal parts are transferred to the other side by the conveyor belt 51, and the sheet metal parts slide down along the inclined plate 54 on the other side, which is convenient for the staff to distinguish and process.

[0037] Working principle: First, place two sheet metal parts on the top of the workbench 1. Then, the output shaft of the first motor 27 drives the first bidirectional threaded rod 25 to rotate. The first bidirectional threaded rod 25 limits the two second clamping plates 24 in cooperation with the second sliding rod 26, and then drives the two second clamping plates 24 to approach each other. This can align the two sheet metal parts. Then, the shortening of the output ends of the two first electric telescopic rods 23 drives the cross plate 22 to move downward. When the cross plate 22 moves downward, it will drive the four connecting rods 21 to rotate. At the same time, the four connecting rods 21 will respectively rotate at the bottom of the two first clamping plates 2. Limited by the second groove 12 and the first sliding rod 211, the two first clamping plates 2 approaching each other can clamp the sheet metal parts. Then, the output shaft of the second motor 44 drives the first threaded rod 43 to rotate. The first threaded rod 43 drives the slide plate 42 to slide on the inner surface of the fourth groove 41. The slide plate 42 drives the mounting plate 46 to slide through the four third electric telescopic rods 45. The mounting plate 46 drives the welding torch 4625 to move to the top of the contact point of the two sheet metal parts. Then, the output shaft of the fourth motor 4622 drives the second threaded rod 4621 to rotate on the inner surface of the sixth groove 462. The second threaded rod 4621 further drives the slider 4623 to slide on the inner surface of the fifth groove 461. At the same time, the slider 4623 drives the fourth electric telescopic rod 4624 and the welding torch 4625 to slide. By extending and shortening the output end of the fourth electric telescopic rod 4624, the position of the welding torch 4625 can be controlled to weld the sheet metal parts. After welding, the welding torch 4625 moves upward and the fifth motor 4626 moves downward. When the grinding wheel 4627 contacts the welding area, the output shaft of the fifth motor 4626 drives the grinding wheel 4627 to rotate. The rotation of the grinding wheel 4627 can clean up the welding slag. At the same time, the welding slag will enter the inner cavity of the collection box 47 through the ventilation pipe 47. This is convenient for the staff to collect and process the welding slag. At the same time, cleaning the welding slag on the sheet metal parts is convenient for subsequent detection of the welding situation.

[0038] After welding, both the welding torch 4625 and the fifth motor 4626 rise. At the same time, the output ends of the four second electric telescopic rods 3 extend, driving the four top pieces 31 to move upward to lift the sheet metal parts. Then, the output shaft of the third motor 4613 drives the second bidirectional threaded rod 4612 to rotate. Through the meshing transmission of the two gears 4614, the two second bidirectional threaded rods 4612 can synchronously drive the two third clamping plates 4611 to approach each other and clamp the sheet metal parts. Then, the slide plate 42 drives the mounting plate 46 to slide to transfer the sheet metal parts. After transferring the sheet metal parts to the top of the conveyor belt 51, the sensor 55 detects the welding area. For qualified sheet metal parts, the output shaft of the sixth motor 52 drives the conveyor roller 5 to rotate and at the same time makes the conveyor belt 51 rotate, which can transfer the sheet metal parts to one side and the sheet metal parts slide down from the inclined plate 54. For unqualified sheet metal parts, the sixth motor 52 rotates in the reverse direction and is transferred to the other side. This is convenient for the staff to distinguish, collect and sort the sheet metal parts.
