Detailed implementation mode

[0018] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with 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 fall within the scope of protection of the present invention.

[0019] As Figures 1 to 7 shown, this embodiment proposes a sheet metal welding device for metal plates, including a welding table 1. A bottom plate 2 is provided at the bottom of the welding table 1. It also includes a support member, a pressing member, a welding torch 3 and a leveling mechanism. The support member is movably installed on the welding table 1. There are two support members. The support member includes a support plate 4. A plurality of telescopic sleeves are provided on the support plate 4. The telescopic sleeve includes a sleeve 5 and a sleeve rod 6 slidably arranged inside the sleeve 5. The sleeve rod 6 is connected to the sleeve 5 through a spring 7. As Figure 6 shown, and a suction cup 8 is provided at the top of each telescopic sleeve. An air pipe is provided on each suction cup 8. The air pipes on the plurality of suction cups 8 are interconnected to ensure simultaneous inhalation and exhalation. The suction pipe belongs to the well-known technology of those skilled in the art, and the air pipe is not shown in the drawings. A pressing member is provided above each support member. The pressing member includes a pressing plate 9 and a hydraulic cylinder 10. And a plurality of telescopic sleeves are also provided at the lower end of the pressing plate 9. And a suction cup 8 is also installed at the output end of each telescopic sleeve. A support 12 is provided on the bottom plate 2. A cross beam 11 is connected between the two hydraulic cylinders 10. The cross beam 11 is parallel to the sliding direction of the adjusting block 13. And supports 12 are provided on both sides of the cross beam 11. The support 12 is fixedly connected to the bottom plate 2. The two ends of the cross beam 11 respectively slide through the supports 12 at the corresponding positions; In this embodiment, since the shape of the sheet metal part is not regular, the installation stability of the hydraulic cylinder 10 can be ensured by setting the bracket 12. The use height of the pressing part can be adjusted up and down by the stably installed hydraulic cylinder 10, and the sheet metal part can be clamped in cooperation with the supporting part. Through the setting of the telescopic sleeve, the supporting part and the pressing part can adaptively clamp the sheet metal part according to the shape of the sheet metal part, so as to ensure the clamping stability of the sheet metal part. Through the setting of the suction cup 8, the clamping stability of the sheet metal part between the supporting part and the pressing part can be further ensured, and lateral sliding can be avoided.

[0020] Two adjusting blocks 13 are slidably arranged at the top end of the welding table 1, and the sliding direction of the adjusting blocks 13 is perpendicular to the moving direction of the welding torch 3. The support plate 4 is connected to the adjusting block 13 at the corresponding position. A dovetail chute 14 is arranged on the welding table 1. A dovetail slide bar 15 matched with the dovetail chute 14 is arranged at the bottom end of the adjusting block 13. The dovetail slide bar 15 is slidably arranged inside the dovetail chute 14. The welding torch 3 is installed in the middle area of the two supporting parts through a moving component, and a guiding rod 16 is arranged on one side of the welding torch 3 for adjusting the use position of the supporting part in combination with the weld between the sheet metal parts. In this embodiment, through the setting of the guiding rod 16, the guiding rod 16 is in the weld between the two clamped sheet metal parts. As the welding torch 3 moves, the guiding rod 16 moves along the direction of the weld, thereby driving the adjusting block 13 to slide horizontally on the welding table 1, ensuring that the welding torch 3 moves along the weld path between the two sheet metal parts, and thus completing the welding.

[0021] It further includes a bidirectional lead screw 17. The bidirectional lead screw 17 threadedly penetrates through the two adjusting blocks 13. A handle 19 is arranged at one end of the bidirectional lead screw 17, and a stop block 18 is installed at the other end of the bidirectional lead screw 17. By rotating the handle 19, the bidirectional lead screw 17 can be driven to rotate, so that the two adjusting blocks 13 can approach or move away from each other on the welding table 1 at the same time, thereby adjusting the distance between the two clamped sheet metal parts, that is, the size of the weld. A leveling mechanism is arranged on the supporting part for leveling the sheet metal part placed on the supporting part. The leveling mechanism includes electric cylinders 20. There are four electric cylinders 20, and the four electric cylinders 20 are arranged in a rectangle on the support plate 4. The top output end of the electric cylinder 20 is provided with a rubber head 21. Through the telescopic action of the electric cylinder 20 and the electric cylinders 20 arranged in a rectangle, the sheet metal part placed on the supporting part can be leveled. Through the setting of the rubber head 21, the damage to the sheet metal part can be reduced. The height of each electric cylinder 20 can be independently adjusted and controlled, so that each sheet metal part can be leveled and supported, and the sheet metal parts on both sides can be ensured to be at the same height, ensuring the effectiveness of welding.

[0022] Correspondingly, the moving component includes a horizontal frame 22 and an adjusting component. A support frame is provided at the bottom of the adjusting component, and the support frame is connected to the bottom plate 2. Two horizontal frames 22 are symmetrically arranged on the adjusting component, and a groove body is provided on the horizontal frame 22. A slider 23 is slidably arranged in the groove body, and a clamping mechanism is arranged on the slider 23. The welding torch 3 is installed in the clamping mechanism. The clamping mechanism includes a clamping plate 24. A clamping groove is provided at the bottom end of the slider 23, and the clamping plate 24 is symmetrically and slidably arranged in the clamping groove. An adjusting screw 25 is rotatably connected to each clamping plate 24, and the adjusting screw 25 threadedly penetrates through the side wall of the clamping groove. The other end of the adjusting screw 25 is provided with a handwheel. A lead screw 26 is rotatably connected to the groove body, and a first motor 27 is installed on the horizontal frame 22. The output end of the first motor 27 is coaxially connected to the lead screw 26. The adjusting component is used to adjust the distance between the two welding torches 3. By rotating the first motor 27, the lead screw 26 can be driven to rotate, so as to drive the slider 23 on the lead screw 26 to move along the direction of the groove body, thereby driving the welding torch 3 to move. Among the two horizontally arranged horizontal frames 22, the welding torch 3 can be installed, so that simultaneous welding can be realized both up and down, or the welding torch 3 located on the upper side or the welding torch 3 located on the lower side can be used alone. The welding torch 3 can be disassembled through the clamping mechanism and selected according to needs. When welding simultaneously up and down, it is not necessary to require the welding torch 3 located on the upper side and the welding torch 3 located on the lower side to move synchronously at the same time. Even if there is an error in the moving distance between the two welding torches 3 up and down, it is allowed.

[0023] In addition, it should be noted that the installation position of the guide rod 16 is on both sides of the slider 23. The guide rod 16 is parallel to the output end of the welding torch 3 to ensure effective guidance for the use position of the welding torch 3. Connecting plates 28 are extended outward on both sides of the slider 23, and the guide rod 16 is detachably connected to the connecting plate 28 by screwing, as Figure 3 shown, to ensure that the installation position of the guide rod 16 is selected in combination with the moving direction of the welding torch 3, and different outer diameters of the guide rod 16 are selected for use in combination with the width of the weld seam. If welding simultaneously up and down, if the upper guide rod 16 is located in the weld seam, the lower guide rod 16 can be disassembled and not used.

[0024] In addition, the adjusting assembly includes an adjusting frame 29 which is connected to the support frame. An adjusting groove is provided inside the adjusting frame 29, and a bidirectional screw 30 is arranged inside the adjusting groove. One ends of two cross frames 22 are both slidably arranged in the adjusting groove, and the two cross frames 22 are respectively threadedly connected to the bidirectional screw 30. A second motor 31 is installed at the top end of the adjusting frame 29, and the bottom output end of the second motor 31 is coaxially connected to the bidirectional screw 30. By rotating the second motor 31, the bidirectional screw 30 can be driven to rotate, so as to ensure that the two cross frames 22 approach or move away from each other along the direction of the adjusting groove, and adjust the distance between the upper and lower welding torches 3 and the weld seam. The support frame includes a sliding frame 32 and a frame body 33. The sliding frame 32 is connected to the bottom plate 2, and the frame body 33 is longitudinally slidably arranged inside the sliding frame 32. The top end of the frame body 33 is connected to the bottom end of the adjusting frame 29, and an electric telescopic rod 34 is installed at the bottom of the frame body 33. The output end of the electric telescopic rod 34 is connected to the bottom end of the frame body 33, and the installation end of the electric telescopic rod 34 is connected to the bottom plate 2. Since the height of the sheet metal parts may change due to leveling when they are placed on the support parts, the height of the adjusting frame 29 can be adjusted by the electric telescopic rod 34 to re-adjust the overall height of the two welding torches 3 in the vertical direction, ensuring that the distances between the upper and lower welding torches 3 and the weld seam are basically the same and ensuring the effectiveness of welding.

[0025] It should be noted that a coordinate system of X, Y, and Z axes is set in the specification drawings. Among them, the sliding direction of the adjusting block 13 is the movement in the X-axis direction, the movement direction of the welding torch 3 is the movement in the Y-axis direction, the adjusting direction of the adjusting assembly and the action direction of the electric telescopic rod 34 are the movements in the Z-axis direction.

[0026] Working principle: During use, first place the two sheet metal parts to be welded on two support parts respectively, and then control the corresponding electric cylinders 20 to ensure that the two sheet metal parts are at the same welding height and level their welding angles. After leveling, control the hydraulic cylinder 10 to extend, driving the pressing part to move downward. Under the action of the telescopic sleeve, cooperate with the suction cup 8 to clamp and suck the sheet metal parts up and down. For the two clamped sheet metal parts, by rotating the handle 19, make them approach or move away from each other on the welding table to adjust the width of the weld seam. Then push the two adjusting blocks 13 to slide on the dovetail-shaped chute 14 to align the guiding rod 16 with the weld seam. Under the action of the electric telescopic rod 34 and the second motor 31, insert the guiding rod 16 into the weld seam. As the welding torch 3 moves in the Y-axis direction, under the action of the guiding rod 16, continuously drive the adjusting block 13 to slide on the dovetail-shaped chute 14 to achieve the purpose of welding the welding torch 3 along the position of the weld seam. Among them, whether the upper and lower welding torches 3 are used simultaneously and the use position of the guiding rod 16 need to be adjusted according to the on-site use situation.

[0027] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention.
