Description

Technical Field

[0001] The present invention relates to the technical field of arc welding devices, and particularly to a metal sheet welding mechanism. Background Art

[0002] Arc welding is a welding method that melts metal through the high temperature generated by an arc to connect them together. According to different operation methods, arc welding can be divided into semi-automatic welding and automatic welding.

[0003] Semi-automatic welding means that during the welding process, the welder manually operates the welding gun, but the feeding of the welding wire is automatically completed by the welding machine. The welder controls the position and welding speed of the welding gun. It has high flexibility and is suitable for welding complex workpieces. The operation is relatively simple and easy to train. It is very suitable for welding tasks that require adjusting the welding position and angle.

[0004] Automatic welding means that the welding process is completely controlled by mechanical equipment without manual intervention. The welding parameters and welding path are set in advance by a computer or other control systems. It has high efficiency and is suitable for large-scale production. The welding quality is stable and the repeatability is good. It has poor adaptability to complex welding positions and is usually suitable for welding standardized and simple structures.

[0005] When welding metal sheets, some metal sheets are relatively long, so the length of the butt ends to be welded is also relatively long, making it difficult to align. The longer butt joint will also cause low alignment degree at the butt ends of the metal sheets, and frequent adjustments are required, reducing the welding efficiency. Therefore, the present invention proposes a metal sheet welding mechanism. Summary of the Invention

[0040] Embodiment 1

[0041] Referring to Figures 1 to 3 , a metal sheet welding mechanism is provided, including a workbench 100; the workbench 100 is a structure for providing support and can provide support for the workpiece to be welded, that is, the workpiece to be welded is placed on the workbench 100 for cutting.

[0042] The metal sheet welding mechanism includes a track portion 200, which is provided with a wheel groove 201; the track portion 200 is fixed to the workbench 100 and spans across the workbench 100, and the track portion 200 plays a supporting role.

[0043] The metal sheet welding mechanism includes a moving seat 300, on which rollers 301 are provided. The rollers 301 are located inside the wheel groove 201. When the moving seat 300 moves, the rollers 301 can move inside the wheel groove 201. A driving structure can be installed on the moving seat 300 to drive the rollers 301 to rotate and move inside the wheel groove 201. Therefore, the entire moving seat 300 can move on the track portion 200.

[0044] The metal sheet welding mechanism includes a welding part 400, which is installed on the moving seat 300; when the moving seat 300 moves, it can drive the welding part 400 to move, and the welding part 400 is the welding structure, which has a welding head 401.

[0045] The metal sheet welding mechanism further includes clamps 500, which are installed on the workbench 100 in pairs. The track part 200 is located between the paired clamps 500. Through the clamps 500, two sheets can be clamped on the workbench 100, and the butt joint position of the two sheets is located below the track part 200, so that the butt joint of the two sheets is parallel to the track part 200. When the moving seat 300 moves on the track part 200, the welding part 400 can weld the butt joint of the two sheets, so that the welding part 400 can stably weld the two sheets. By driving the welding part 400 to move along the butt joint of the sheets through the moving seat 300, the welding range of a single welding part 400 can be improved, so that a single welding device only needs to be equipped with a welding part 400 to complete the welding work over a long distance.

[0046] The workbench 100 is provided with a docking standard groove 101. The purpose of setting the docking standard groove 101 is to align the butt joint of the two sheets with the track part 200. Align the butt joint of the two sheets with the docking standard groove 101 on the workbench 100. When the moving seat 300 moves on the track part 200, the welding part 400 on the moving seat 300 can weld the butt joint of the two sheets. By arranging the docking standard groove 101 between the paired clamps 500, the clamps 500 can clamp the sheets from both ends to the middle to help align the butt ends of the sheets.

[0047] Embodiment 2

[0048] What is different about this embodiment from the first embodiment is: referring to Figures 3 to 7 , the metal sheet welding mechanism further includes an alignment part 600. The alignment part 600 includes a first blocking piece 601 and a second blocking piece 602 that can be lifted and lowered and are installed in the docking standard groove 101; the first blocking piece 601 and the second blocking piece 602 are independent of each other and can both be lifted and lowered in the docking standard groove 101.

[0049] A first limiting side 601a is provided on the side of the first blocking piece 601 away from the second blocking piece 602, a second limiting side 602a is provided on the side of the second blocking piece 602 away from the first blocking piece 601, and a replacement limiting side 602b is provided on the side of the second blocking piece 602 close to the first blocking piece 601.

[0050] When placing the first plate, the butt end of the first plate contacts the first limiting side 601a, and when placing the second plate, the butt end of the second plate contacts the second limiting side 602a, and then the first blocking member 601 is lowered and withdrawn, pushing the first plate, so that the butt end of the first plate contacts the replacement limiting side 602b. At this time, the clamp 500 positions the first plate, and then the second blocking member 602 is lowered and withdrawn, pushing the second plate, so that the butt end of the second plate contacts the butt end of the first plate, thereby stably aligning the first plate and the second plate at the position of the replacement limiting side 602b. It is only necessary to align the welding position of the welding part 400 with the replacement limiting side 602b in advance to achieve the purpose of aligning the butt position of the first plate and the second plate with the welding part 400.

[0051] Furthermore, the metal sheet welding mechanism also includes a pushing part 700; it includes a translation member 701, which can be movably installed on the workbench 100; a horizontal column 702, which is connected to the translation member 701; a resistance member 703, which is installed on the horizontal column 702, and the resistance member 703 resists the alignment part 600; when the resistance member 703 moves toward the alignment part 600, it can push the alignment part 600 to rise along the docking standard groove 101, and when the resistance member 703 moves away from the alignment part 600, the docking standard groove 101 can fall back along the docking standard groove 101.

[0052] Among them, the first blocking member 601 and the second blocking member 602 both have multiple blocking blocks 603, and the multiple blocking blocks 603 are fixed together by a through shaft 604. In this embodiment, the number of the pushing parts 700 is two, and the two pushing parts 700 are used to drive the first blocking member 601 and the second blocking member 602 respectively.

[0053] When the translation member 701 moves, it can drive the horizontal column 702 to move, and the resistance member 703 carried by the horizontal column 702 can move, wherein there are multiple resistance members 703 which are all installed on the horizontal column 702 and correspond to the blocking blocks 603 one by one. By the resistance member 703 approaching the blocking block 603, the blocking block 603 can be squeezed to move upward, and by the resistance member 703 moving away from the blocking block 603, the blocking block 603 is lowered under the action of gravity.

[0054] Furthermore, an oblique pushing side 703 a is provided on the resisting member 703 , and the oblique pushing side 703 a of the resisting member 703 contacts the aligning portion 600 .

[0055] The oblique push side 703a is disposed on the resisting member 703, and the oblique push side 703a and the blocking block 603 always maintain contact. There is a height difference between the two ends of the oblique push side 703a, so when the resisting member 703 moves, the blocking block 603 can be lifted and lowered.

[0056] Furthermore, the pushing part 700 also includes a mounting rail 704 installed on the workbench 100; the translation member 701 includes a moving body 701a slidably installed on the mounting rail 704, an extension shaft 701b connected to the moving body 701a, and a connecting head 701c installed on the extension shaft 701b; the cross column 702 is connected to the extension shaft 701b through the connecting head 701c.

[0057] The installation position of the mounting rail 704 is located on the back of the workbench 100 where the plate is placed. The movable body 701a can move along the mounting rail 704, thereby driving the extension shaft 701b to move. When the extension shaft 701b moves, it drives the connecting head 701c to move, thereby driving the horizontal column 702 to move synchronously, and then driving the resistance member 703 to move.

[0058] The mounting rail 704 is arranged perpendicular to the track portion 200 , and when the moving member moves back and forth linearly, it can approach or move away from the track portion 200 .

[0059] Furthermore, the pushing part 700 also includes a fixing pin 705 installed on the workbench 100, and an elastic member 706 arranged between the fixing pin 705 and the connecting head 701c; the elastic member 706 is sleeved on the outer side of the extension shaft 701b, one end of the elastic member 706 is in contact with the fixing pin 705, and the other end of the elastic member 706 is in contact with the connecting head 701c.

[0060] The elastic member 706 is a spring.

[0061] Under the elastic force of the elastic member 706, the elastic member 706 pushes the connecting head 701c toward the track portion 200, so that the resistance block can maintain the state of pushing the blocking block 603 upward. Therefore, without being affected by external force, the resistance block maintains the state of extending from the docking standard groove 101 to the top of the workbench 100, so that when the plate is placed, the end of the plate can be in contact with the resistance block. When the resistance block needs to be lowered, it is only necessary to apply a thrust to the movable body 701a to move the connecting head 701c away from the track portion 200, so that the blocking block 603 can fall back.

[0062] Therefore, in this embodiment, first, the butt ends of the two plates to be welded respectively contact the first blocking member 601 and the second blocking member 602. When the contact is completed, one of the movable bodies 701a is pulled so that the connecting head 701c overcomes the elastic force of the elastic member 706 and moves away from the track portion 200, thereby driving the contact block to change its position and causing the blocking block 603 to drop.

[0063] Pushing the first plate can make the docking end of the first plate abut against the replacement limiting side 602b. At this time, the fixture 500 positions the first plate. As above, in this way, the first plate and the second plate are butted and abutted at the position of the replacement limiting side 602b, and the purpose of aligning the docking position of the first plate and the second plate with the welding part 400 can be achieved.

[0064] The remaining structures are the same as those in Embodiment 1.

[0065] Embodiment 3

[0066] Refer to Figure 3 、 Figures 7 to 9 In this embodiment, different from the above embodiments, the fixture 500 includes a pushing member 501 slidably mounted on the workbench 100, a fixed shaft 502 fixed to the pushing member 501, a rotating disk 503 rotatably mounted on the fixed shaft 502, a grip 504 mounted on the rotating disk 503, and a clamping arm 505 fixed to the grip 504.

[0067] Among them, the pushing member 501 can move on the workbench 100, so that the fixture 500 can clamp plates of different sizes. The fixed shaft 502 can move synchronously with the pushing member 501. By the grip 504, the rotating disk 503 can be driven to rotate outside the fixed shaft 502, thereby driving the clamping arm 505 to rotate. When the clamping arm 505 rotates towards the plate, the clamping arm 505 can abut against the plate, thereby clamping the plate.

[0068] In order to clamp stably, the rotating disk 503 and the fixed shaft 502 can be connected by a ratchet disk structure with one-way locking. As Figure 9 shown, an elastic reed 503a and a positioning tooth disk 503b are arranged on the rotating disk 503, and a reverse ratchet disk 502a is fixed on the fixed shaft 502. The reverse ratchet disk 502a can lock the positioning tooth disk 503b unidirectionally. When unlocking is required, only need to push the positioning tooth disk 503b away from the reverse ratchet disk 502a.

[0069] Specifically, side shafts 701d arranged in a straight line are installed on the side wall of the translation member 701; the fixture 500 includes a mounting bracket 506 mounted on the rotating disk 503, and a one-way rotating pin 507 mounted on the mounting bracket 506.

[0070] Among them, side shafts 701d are arranged on both sides of the translation member 701, and the side shafts 701d are arranged in a straight line. A gap is provided between each adjacent side shaft 701d. The one-way rotating pin 507 is installed on the mounting bracket 506 through an automatically resilient rotating shaft. Limiting protrusions are provided on the mounting bracket 506. As Figure 8 shown, the limiting protrusions limit the one-way rotating pin 507 to only rotate counterclockwise, but cannot rotate clockwise.

[0071] The one-way rotating pin 507 extends between the side shafts 701d. After placing the plate on the workbench 100, when the pusher 501 approaches the plate, the one-way rotating pin 507 can rotate counterclockwise through the multiple side shafts 701d. When it reaches the corresponding position of the plate, by rotating the grip 504 towards the plate, the one-way rotating pin 507 will push the side shaft 701d, thereby pushing the moving body 701a to move away from the track portion 200. At this time, the connecting head 701c can press the elastic member 706, and the connecting head 701c drives the abutting block to move, and the blocking block 603 can fall down.

[0072] Therefore, when rotating the grip 504, the corresponding blocking block 603 can be made to fall down, and then the plate can be positioned and clamped, making the whole operation more convenient.

[0073] Furthermore, a first rail 704a and a second rail 704b are provided on the mounting rail 704; the side shaft 701d on the translating member 701 extends to the inside of the first rail 704a, and the translating member 701 is slidably mounted on the workbench 100 through the first rail 704a; the pusher 501 is slidably mounted on the workbench 100 through the second rail 704b.

[0074] All other structures are the same as those in Embodiment 2.
