Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0031] Example:

[0032] like Figure 1-8 As shown, an embodiment of the present invention provides a double-track gantry welding device, including a bottom plate 1, a lateral moving component 2 is arranged on the top of the bottom plate 1, and the lateral moving component 2 is mainly used to control the laser welding head 10 to move left and right, and a longitudinal moving component 3 is arranged on the lateral moving component 2, and the longitudinal moving component 3 is mainly used to control the laser welding head 10 to move forward and backward;

[0033] A protective shell 4 is fixedly connected to the left side wall of the longitudinal moving component 3, and a first sliding hole 7 is arranged on the left side wall of the protective shell 4. The setting of the first sliding hole 7 facilitates the upward and downward movement of the fixed block 12. An electric cylinder 5 is fixedly connected to the top of the protective shell 4. The setting of the electric cylinder 5 is mainly used to control the laser welding head 10 and the cleaning block 18 to move up and down. The movable end of the electric cylinder 5 is fixedly connected to a connecting rod 6, and the bottom end of the connecting rod 6 is fixedly connected to a mounting seat 9. The bottom of the mounting seat 9 is fixedly connected to the laser welding head 10. A fixed block 12 is fixedly connected to the circumferential surface of the connecting rod 6, and the fixed block 12 is located inside the first sliding hole 7. A receiving plate 13 is fixedly connected to the side wall of the fixed block 12, and a telescopic rod 14 is fixedly connected to the bottom of the receiving plate 13. The telescopic rod 14 itself has a telescopic function. The bottom end of the telescopic rod 14 is fixedly connected to a mounting block 15. A first spring 16 is sleeved on the circumferential surface of the telescopic rod 14. The first spring 16 is always in a compressed state. When the laser welding After the joint 10 returns to the initial position (the laser welding head 10 is stored inside the protective shell 4), the telescopic rod 14 is in a fully expanded state. At this time, the cleaning block 18 is located below the laser welding head 10. During the welding process of the laser welding head 10, the cleaning block 18 is tightly attached to the object to be welded under the action of the first spring 16 (it should be noted that the welding method of the present technical solution is to weld from right to left, and the cleaning block 18 is always located on the welding track of the laser welding head 10. If the welding direction changes, the direction of the object to be welded needs to be adjusted). A card slot 17 is provided at the bottom of the mounting block 15, and the cleaning block 18 is carded inside the card slot 17. The setting of the card slot 17 facilitates the replacement of the cleaning block 18. The top of the cleaning block 18 is a solid component that will not be deformed. The bottom of the cleaning block 18 is a detachable elastic cleaning component. The bottom cleaning component can be replaced separately after each use. The front shape of the entire cleaning block 18 is T-shaped.

[0034] A storage cylinder 19 is fixedly connected to the top right edge of the bottom plate 1, and a storage cavity 20 is arranged inside the storage cylinder 19. The interior of the storage cavity 20 is mainly used to store the cleaning block 18. A through hole 21 is arranged at the bottom of the storage cavity 20. The arrangement of the through hole 21 facilitates the push plate 26 to push the cleaning block 18 inside the storage cavity 20 into the interior of the card slot 17. A fixing frame 22 is fixedly connected to the front side wall of the storage cylinder 19, and a first extrusion plate 23 is slidably connected inside the fixing frame 22. A push plate 26 is fixedly connected to the rear side wall of the first extrusion plate 23, and the push plate 26 is located inside the through hole 21. A second spring 2 is arranged between the first extrusion plate 23 and the storage cylinder 19. 7, and the second spring 27 is sleeved on the push plate 26. When the extrusion block 34 releases the top plate 31, the second spring 27 controls the first extrusion plate 23 to drive the push plate 26 to move, and restores the push plate 26 to the initial position. At this time, the cleaning block 18 inside the storage chamber 20 will automatically move down, and the cleaning block 18 at the bottom layer is aligned with the through hole 21. The interior of the push plate 26 is provided with an extrusion chamber 28, and the rear inner wall of the extrusion chamber 28 is fixedly connected with the third spring 29. When the extrusion block 34 extrudes the top plate 31, the mounting block 15 just moves to the position of the through hole 21 and blocks the cleaning block 18 inside the through hole 21. At this time, the push plate 26 remains stationary, and the top plate 31 is pressed by the third spring 29. The plate 31 is squeezed by the squeezing block 34, and the third spring 29 is compressed. When the mounting block 15 returns to the initial position, the slot 17 is aligned with the through hole 21. At this time, the cleaning block 18 inside the through hole 21 is not released. Then, the elastic force of the third spring 29 is used to squeeze the push plate 26, so that the push plate 26 pushes the cleaning block 18 inside the through hole 21 into the slot 17, and at the same time, the cleaning block 18 inside the slot 17 is pushed out from the slot 17 after use, so as to realize automatic replacement. When the next welding is performed, the squeezing block 34 will loosen the top plate 31. At this time, the push plate 26 is reset under the action of the second spring 27, and the top plate 31 is reset under the action of the third spring 29. The third spring 29 is reset under the action (it should be noted that after each welding is completed, the laser welding head 10 and the mounting block 15 will be reset, and the reset order is that the electric cylinder 5 is reset first, then the second motor 304 is reset, and finally the first motor 203 is reset). The front end of the third spring 29 is fixedly connected to the second extrusion plate 30, and the front side wall of the second extrusion plate 30 is fixedly connected to the top plate 31. The front end of the top plate 31 is provided with an inclined surface 32.

The longitudinal moving component 3 is fixedly connected to the connecting block 33, and the left side wall of the connecting block 33 is fixedly connected to the extrusion block 34.

[0035] The lateral movement assembly 2 includes a guide rail 201, a sliding cavity 202, a first motor 203, a first threaded rod 204 and a sliding rod 205. The first motor 203 is mainly used to control the rotation of the first threaded rod 204, so that the gantry 301 drives the laser welding head 10 to move left and right. When the first motor 203 rotates forward, the laser welding head 10 moves to the left. When the first motor 203 rotates reversely, the laser welding head 10 moves to the right. The left and right side walls of the guide rail 201 are both provided with sewage outlets (such as Figure 1 As shown), when the first motor 203 controls the gantry 301 to move left and right, the gantry 301 will push the debris and dirt inside the sliding cavity 202 to the sewage outlet, and finally discharge them, so as to facilitate the cleaning of the inside of the sliding cavity 202;

[0036] There are two guide rails 201, which are fixedly connected to the front and rear edge positions of the top of the base plate 1, the sliding cavity 202 is set at the top of the guide rail 201, the first motor 203 is fixedly connected to the right side wall of the rear guide rail 201, the first threaded rod 204 is fixedly connected to the output shaft of the first motor 203, and the first threaded rod 204 is rotatably connected to the guide rail 201, the sliding rod 205 is fixedly connected to the inner wall of the front guide rail 201, and a hydraulic cylinder 35 is fixedly connected to the inner wall of the guide rail 201. The hydraulic cylinder 35 is mainly used to control the movement of the positioning plate 36, so as to position the object to be welded to avoid shaking during the welding process. The movable end of the hydraulic cylinder 35 is fixedly connected to the positioning plate 36. There are four hydraulic cylinders 35, and two are set in a group, corresponding to the guide rails 201 on the front and rear sides. Each group of hydraulic cylinders 35 is provided with a positioning plate 36, and the positioning plate 36 is located on the left side of the storage tube 19.

[0037] The longitudinal moving assembly 3 includes a gantry 301, a guide groove 302, a second threaded rod 303, a second motor 304, a threaded block 305 and a slide 306. The second motor 304 is mainly used to control the rotation of the second threaded rod 303, so that the threaded block 305 and the slide 306 drive the laser welding head 10 to move forward and backward. When the second motor 304 rotates forward, the laser welding head 10 moves backward. When the second motor 304 rotates reversely, the laser welding head 10 moves forward.

[0038] The gantry 301 is slidably connected to the inside of the sliding cavity 202, the gantry 301 is threadedly connected to the first threaded rod 204, the gantry 301 is slidably connected to the sliding rod 205, the guide groove 302 is set at the top of the gantry 301, the second threaded rod 303 is rotatably connected to the inner wall of the guide groove 302, the second motor 304 is fixedly connected to the front side wall of the gantry 301, and the second threaded rod 303 is fixedly connected to the output end of the second motor 304, the threaded block 305 is threadedly connected to the second threaded rod 303, the slide 306 is slidably connected to the top of the gantry 301, and the threaded block 305 is fixedly connected to the slide 306.

[0039] The protective shell 4 is fixedly connected to the left side wall of the slide 306, the connecting block 33 is fixedly connected to the left side wall of the gantry 301, and the side wall of the mounting seat 9 is fixedly connected with a protective cover 11. In addition, after the laser welding head 10 is received in the protective shell 4, the protective cover 11 will also be received in the protective shell 4 to achieve the protection of the protective cover 11. The protective cover 11 mainly protects the eyes of the staff. The right side wall of the slide 306 is fixedly connected with an exhaust fan 37, which is mainly used to exhaust toxic and harmful gases generated during laser welding. Extraction is carried out, and the toxic and harmful gases are transported to external gas purification treatment equipment (not shown in the figure) for treatment through the exhaust pipe 38 and the delivery pipe 39. The air inlet of the exhaust fan 37 is fixedly connected with the exhaust pipe 38, and the exhaust pipe 38 is fixedly connected to the protective cover 11, and the air outlet of the exhaust fan 37 is fixedly connected with the delivery pipe 39. A second sliding hole 8 is provided on the right side wall of the protective shell 4, and the exhaust pipe 38 is located inside the second sliding hole 8. The setting of the second sliding hole 8 facilitates the exhaust pipe 38 to move up and down with the protective cover 11.

[0040] Limiting grooves 24 are provided on the left and right side walls of the fixing frame 22. The limiting grooves 24 are internally slidably connected to the limiting blocks 25, and the limiting blocks 25 are fixedly connected to the first extrusion plate 23. The setting of the limiting grooves 24 and the limiting blocks 25 is mainly to limit the first extrusion plate 23, so that the first extrusion plate 23 can move stably. The top view shape of the telescopic rod 14 is square to prevent the telescopic rod 14 from rotating, ensuring that the slot 17 can be aligned with the through hole 21 after the mounting block 15 is reset. The extrusion block 34 is located just in front of the slot 17. The extrusion block 34 is used in conjunction with the top plate 31. The through hole 21 and the slot 17 are correspondingly arranged. The elastic force of the third spring 29 is greater than the elastic force of the second spring 27, so that the compressed third spring 29 can push the push plate 26 to move.

[0041] The laser welding head 10, the first motor 203, the second motor 304, the electric cylinder 5 and the exhaust fan 37 in the present application are all controlled by an external controller (not shown in the figure), and the hydraulic cylinder 35 is controlled by a corresponding hydraulic system.

[0042] Working principle: When in use, first place the object to be welded between the two positioning plates 36, then the hydraulic cylinder 35 controls the positioning plates 36 to clamp and fix the object, and then the laser welding head 10 is moved to the position where welding is required through the first motor 203 and the second motor 304. When the extrusion block 34 releases the top plate 31, the push plate 26 is reset under the action of the second spring 27, and the top plate 31 is reset under the action of the third spring 29. The cleaning block 18 inside the storage cavity 20 will automatically move down, and the cleaning block 18 at the bottom layer is aligned with the through hole 21. When welding, the electric cylinder 5 controls the laser welding head 10 to move down to the specified position (the distance between the position to be welded is 1-3mm). At this time, the cleaning block 18 is tightly attached to the object under the action of the first spring 16, and the laser welding head 10 is started. At the same time, the first motor 203 rotates forward and the exhaust fan 37 starts working. The laser welding head 10 moves to the left for welding, and the cleaning block 1 8. Clean the dust at the welding site. After welding is completed, the laser welding head 10 stops working. At the same time, the laser welding head 10 and the cleaning block 18 are reset under the action of the first motor 203, the second motor 304 and the electric cylinder 5. When the extrusion block 34 extrudes the top plate 31, the mounting block 15 just moves to the position of the through hole 21 and blocks the cleaning block 18 inside the through hole 21. At this time, the push plate 26 remains stationary, and the top plate 31 is squeezed by the extrusion block 34. At this time, the third spring 29 is compressed. When the mounting block 15 returns to the initial position, the slot 17 is aligned with the through hole 21. At this time, the cleaning block 18 inside the through hole 21 is not released. Then, the elastic force of the third spring 29 is used to squeeze the push plate 26, so that the push plate 26 pushes the cleaning block 18 inside the through hole 21 into the inside of the slot 17, and at the same time, the cleaning block 18 used in the slot 17 is pushed out from the inside of the slot 17, thereby realizing automatic replacement.
