Description

Technical Field

[0001] The present invention relates to the field of welding technology, and in particular to a welding device with a positioning structure for producing new energy automobile parts. Background Art

[0002] Welding, also known as fusion, is a manufacturing process and technology that joins metals or other thermoplastic materials such as plastics by heating, high temperature or high pressure. There are many sources of energy for modern welding, including gas flame, arc, laser, electron beam, friction and ultrasound. In addition to being used in factories, welding can also be carried out in a variety of environments, such as outdoors, underwater and in space. No matter where it is, welding may bring danger to the operator, so appropriate protective measures must be taken when welding.

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0021] reference Figures 1 to 9A welding device with a positioning structure for the production of new energy vehicle parts includes a welding table 1, a plurality of supporting legs 2 are fixedly provided on the lower side of the welding table 1, a centering positioning component is provided on the upper side of the welding table 1, and the centering positioning component is used to center two circular parts.

An H-shaped block 7 is rotatably provided on the outer periphery of the dual-purpose wheel 3, and a control shaft 8 is rotatably provided on the inner side of the dual-purpose wheel 3. A second centering component is provided above the dual-purpose wheel 3, and the second centering component includes a guide frame 11, which is fixed on the outer periphery of the circular plate 4, and the guide frame 11 is L-shaped Structure, a guide groove is provided on the upper side of the guide frame 11, a guide plate 12 is rotatably provided on the outer periphery of the control shaft 8, the guide plate 12 slides on the inner side of the guide groove, an adjusting sleeve 13 is fixedly provided on the upper side of the guide plate 12, an adjusting rod 14 is slidably provided on the inner side of the adjusting sleeve 13, a centering wheel 15 is rotatably provided on the upper side of the adjusting rod 14, a plurality of first threaded holes are provided on the upper side of the adjusting sleeve 13, a first bolt 16 is provided on the inner side of the first threaded hole through a threaded connection, the lower end of the first bolt 16 is in contact with the upper side of the adjusting rod 14, before use, it is necessary to adjust the position of the centering wheel 15 according to the size of the circular part above, when it is necessary to adjust the position of the centering wheel 15, it is necessary to first loosen the first bolt 16, and then move the adjusting rod 14 to adjust the centering wheel 15 After the adjustment is completed, the first bolt 16 needs to be tightened. It should be noted that the three centering wheels 15 need to be adjusted to be evenly distributed around the circumference, and the centering wheels 15 need to be able to contact the circular parts above to ensure that the circular parts above can be stably clamped. The H-shaped block 7 slides on the inner side of the H-shaped hole 6. A control disk 9 is rotatably provided on the outer periphery of the vertical shaft 5. A plurality of oblique control holes 10 are provided on the upper side of the control disk 9. The control shaft 8 slides on the inner side of the oblique control hole 10. A plurality of pads are fixed on the upper side of the circular plate 4. There are three dual-purpose wheels 3, H-shaped holes 6, and oblique control holes 10. The dual-purpose wheels 3, H-shaped holes 6, and oblique control holes 10 are equally divided around the circumference. After adjusting the centering wheel 15, the two circular parts need to be adjusted. During welding, it is also necessary to first place the lower circular part on the circular plate 4, and then insert the upper circular part into the lower circular part, and then the two circular parts can be clamped. When the two circular parts need to be clamped, the control disk 9 needs to be rotated. When the control disk 9 rotates, the control shaft 8 will slide on the inner side of the inclined control hole 10. Since the inclined control hole 10 is an inclined structure, the control shaft 8 will be close to the center of the control disk 9, so the control shaft 8 will drive the H-shaped blocks 7 to approach each other. When the H-shaped blocks 7 approach each other, the dual-purpose wheels 3 and the centering wheels 15 will also approach each other, so that the lower circular part can be clamped between multiple dual-purpose wheels 3, and the upper circular part can be clamped between multiple centering wheels 15, so that double clamping can be completed.

[0022] like Figures 2 to 4 , Figure 6 As shown, a rotation drive assembly is provided on one side of the centering positioning assembly, and the rotation drive assembly is used to drive the centering positioning assembly to clamp and release. The rotation drive assembly includes a hydraulic cylinder 17 and a follower frame 21. The hydraulic cylinder 17 is externally connected to an electromagnetic valve through an oil pipe. Before use, the hydraulic cylinder 17 is in a fully retracted state. The hydraulic cylinder 17 is fixed on the upper side of the welding table 1. A translation frame 18 is fixed on the axial end of the hydraulic cylinder 17. A translation seat 19 and a translation bending rod 20 are fixed on the translation frame 18. The translation frame 18 is located between the translation seat 19 and the translation bending rod 20. The translation frame 18, the translation seat 19, and the translation bending rod 20 slide on the upper side of the welding table 1. A second drive assembly is provided between the control disk 9 and the translation seat 19. The second drive assembly includes a second gear 26, and the second gear 26 is fixed on the outer periphery of the control disk 9. One side of the translation seat 19 is provided A T-shaped rod 27 is slidably provided on the inner side of the slide groove, and a second rack 28 is fixedly provided on one side of the T-shaped rod 27. The second rack 28 is transmission-connected with the second gear 26 through meshing. A U-shaped cover 29 is fixedly provided on the other side of the translation seat 19, and a fixed plate 30 is fixedly provided on one side of the U-shaped cover 29. A force-bearing plate 31 is fixedly provided on the other side of the T-shaped rod 27, and a tension spring 32 is fixedly provided between the force-bearing plate 31 and the fixed plate 30. When it is necessary to clamp the two circular parts, it is necessary to control the hydraulic cylinder 17 to extend. When the hydraulic cylinder 17 is extended, the translation frame 18 and the translation seat 19 will move, and the translation seat 19 will drive the T-shaped rod 27 and the second rack 28 to move together. When the second rack 28 moves, the second gear 26 and the control disk 9 will rotate. When the control disk 9 rotates, automatic clamping can be achieved, thereby achieving automatic clamping.

[0023] like Figure 1 , Figure 4 , Figure 6As shown, the rotary drive assembly is used to drive the circular part to rotate, specifically: the rotary drive assembly is used to drive a dual-purpose wheel 3 to rotate. After the dual-purpose wheel 3 clamps the circular part, the dual-purpose wheel 3 rotates to drive the circular part to rotate. Two connecting holes are provided on one side of the translation seat 19. The follower frame 21 slides on the inner side of the two connecting holes. The follower frame 21 is a U-shaped structure. A circular tube 22 is fixedly provided on the lower side of a dual-purpose wheel 3. A follower block 23 is rotatably provided on the outer periphery of the circular tube 22. The follower block 23 slides on one side of the follower frame 21. A first rack 24 is fixedly provided on one side of the follower frame 21. A first gear 25 is fixedly provided on the outer periphery of the circular tube 22. The first gear 25 is connected to the first rack 24 through meshing. A control shaft 8 rotates on the inner side of the circular tube 22. When clamping the two circular parts, the dual-purpose wheel 3 contacts the circular parts. It will stop moving, and the clamping will be completed. Then the hydraulic cylinder 17 needs to be controlled to continue to extend. At this time, the control disk 9 will not be able to continue to rotate, so the T-bar 27 will not be able to continue to move, and the translation seat 19 will continue to move, and then the tension spring 32 will be stretched, and the translation seat 19 will drive the follower frame 21 and the first rack 24 to move together when moving. When the first rack 24 moves, the first gear 25, the round tube 22 and a dual-purpose wheel 3 will rotate. Therefore, after the dual-purpose wheel 3 clamps the circular part below, the circular part below can be driven by the dual-purpose wheel 3 to rotate, and the tension of the tension spring 32 will cause several dual-purpose wheels 3 to clamp the circular part below, thereby ensuring that the dual-purpose wheel 3 can drive the circular part below to rotate, and when the circular part below starts to rotate, the circular part can be welded by the welding assembly.

[0024] like Figures 1 to 3 , Figure 5As shown, a welding assembly is provided on the other side of the centering positioning assembly, and the welding assembly is used for welding between two circular parts. The centering positioning assembly is located between the welding assembly and the rotating drive assembly. The welding assembly and the rotating drive assembly are located on the upper side of the welding table 1. The welding assembly includes a laser welding machine, and the laser welding machine includes a laser welding head 33. A moving seat 34 is slidably provided on the upper side of the welding table 1. The rotating drive assembly is used to drive the welding assembly to automatically approach and automatically move away from the centering positioning assembly. Specifically, a horizontal movement is provided between the moving seat 34 and the translation bending rod 20. The translation drive assembly includes a translation shaft 38, a translation rod 39 is rotatably provided on the outer periphery of the translation shaft 38, a guide sleeve 40 is slidably provided on the outer periphery of the translation rod 39, a through hole is provided on one side of the moving seat 34, the guide sleeve 40 is fixed on the inner side of the through hole, the translation rod 39 slides on the inner side of the guide sleeve 40, a third threaded hole is provided on the upper side of the guide sleeve 40, a third bolt 41 is provided on the inner side of the third threaded hole through threaded connection, the lower end of the third bolt 41 is in contact with the translation rod 39, and a driving curved groove 42 is provided on the upper side of the translation curved rod 20. The translation axis 38 slides on the inner side of the driving curved groove 42. When the circular part is clamped, the hydraulic cylinder 17 is controlled to extend. When the hydraulic cylinder 17 extends, the translation frame 18 and the translation bending rod 20 are moved. When the translation bending rod 20 moves, the translation axis 38 slides on the inner side of the driving curved groove 42. Since the driving curved groove 42 is a curved structure, the translation bending rod 20 can translate the translation axis 38, the translation rod 39 and the moving seat 34 through the driving curved groove 42 when moving, so that the moving seat 34 can be moved when welding is required. When the welding is completed, the hydraulic cylinder 17 is controlled to retract, so that the movable seat 34 can automatically move away from the circular part. It should be noted that before use, the distance between the translation axis 38 and the movable seat 34 needs to be adjusted according to the welding position so that the laser welding head 33 can be accurately aligned with the weld. When adjusting the distance between the translation axis 38 and the movable seat 34, the third bolt 41 needs to be loosened first, and then the movable seat 34 can be adjusted by sliding. After the adjustment is completed, the third bolt 41 can be tightened to lock it.

[0025] like Figure 2 , Figure 3As shown, a connecting frame 35 is fixedly provided on one side of the movable seat 34, and the connecting frame 35 is a U-shaped structure. A mounting frame 36 is fixedly provided on the lower side of the laser welding head 33, and the mounting frame 36 slides on the inner side of the connecting frame 35. A second threaded hole is provided on one side of the connecting frame 35, and a second bolt 37 is provided on the inner side of the second threaded hole through a threaded connection. One end of the second bolt 37 is in contact with the mounting frame 36. Before use, it is also necessary to adjust the height of the laser welding head 33 according to the thickness of the circular part below or the height of the weld. When adjusting the height of the laser welding head 33, it is necessary to first The height of the laser welding head 33 can be adjusted by loosening the second bolt 37 and then adjusting the height of the mounting bracket 36 up and down. After the adjustment is completed, the second bolt 37 can be tightened to lock it. When welding is required, the laser welding machine is turned on and the two circular parts are welded by the laser welding head 33 to realize automatic welding. During welding, the two circular parts need to be clamped and the hydraulic cylinder 17 needs to be controlled to extend continuously to rotate the circular parts, thereby realizing automatic continuous welding and continuously welding circular welds.

[0026] like Figures 7 to 9As shown, an oiling assembly is provided on one side of the mounting frame 36, and the oiling assembly includes an extension frame 43 and a cylinder 45. The extension frame 43 is fixed on one side of the mounting frame 36, and a square tube 44 is fixed on one side of the extension frame 43. The cylinder 45 is externally connected to a solenoid valve through an air pipe, and a connecting seat 46 is fixed on the outer periphery of the cylinder 45, and the connecting seat 46 is fixed on the square tube 44. A reciprocating block 47 is slidably provided on the inner side of the square tube 44, and the axial end of the cylinder 45 is fixed on one side of the reciprocating block 47, and an oiling brush 48 is fixed on the other side of the reciprocating block 47. An oil inlet hole is provided on one side of the square tube 44, and an oil inlet pipe 49 is fixed on the inner side of the oil inlet hole. An oil storage box 50 is fixed on the outer periphery of the tube 49. Before use, a proper amount of anti-rust oil needs to be poured into the oil storage box 50. The oil storage box 50 is fixed on the upper side of the square tube 44. A rubber block 51 is fixed on one side of the reciprocating block 47. An oil groove is provided on the inner wall of the square tube 44. An oil hole is provided on one side of the reciprocating block 47. During welding, when the laser welding head 33 is turned on and the circular part rotates one circle, the welding is completed. At this time, it is necessary to control the laser welding head 33 to stop welding, and at the same time control the hydraulic cylinder 17 to stop extending, and then control the cylinder 45 to extend. The extension of the cylinder 45 will drive the oiling brush 48 to extend from the square tube 44. The oiling brush 48 will come out, and will contact the two circular parts and the weld, and then the hydraulic cylinder 17 will be controlled to retract. When the hydraulic cylinder 17 is retracted, the circular part will rotate in the opposite direction, so that a circle of anti-rust oil can be applied on the circular weld, thereby realizing automatic oiling. After the oiling is completed, the air cylinder 45 needs to be controlled to retract so that the oiling brush 48 can enter the square tube 44. During the extension of the air cylinder 45, the rubber block 51 cannot block the oil inlet hole, and the anti-rust oil in the oil storage box 50 can enter the square tube 44 through the oil inlet pipe 49 and the oil inlet hole. The anti-rust oil entering the square tube 44 will drip or flow into the oil groove through the oil outlet hole, and During the retraction of the cylinder 45, the oiling brush 48 will be in the square tube 44, and the rubber block 51 will block the oil inlet to stop the oil supply, and the oiling brush 48 will absorb the oil in the oil tank, thereby realizing automatic and appropriate oil supply, and then the hydraulic cylinder 17 is controlled to retract, so that the moving seat 34 can automatically move away from the circular part, and the dual-purpose wheel 3 and the centering wheel 15 can be moved away from each other to loosen the circular part, and the tension spring 32 can also be shortened and reset. When the hydraulic cylinder 17 is fully retracted, the equipment can be in the initial state and automatic reset can be completed. Then the material can be replaced through the material replacement equipment, and the operation can be repeated to carry out continuous processing.
