Description

Technical Field

[0001] This application relates to the field of steel plate welding technology, and in particular to a welding apparatus and welding method for stainless steel composite steel plates. Background Technology

[0002] Metal composite panels are a new type of sheet material made by combining two or more different metal materials through a specific process.

[0003] Metal composite panels combine the performance advantages of different metals, such as combining high-strength metals with corrosion-resistant metals to obtain panels that are both strong and resistant to corrosion. For example, combining stainless steel with ordinary carbon steel can ensure strength while reducing costs and improving corrosion resistance.

[0004] When welding metal composite panels, different welding materials are required because the composite panels are made of different materials.

[0005] The existing technical solutions mentioned above have the following drawbacks: When welding existing composite steel plates, workers need to fix the two steel plates that need to be joined together, and then use different welding materials to weld the two sides of the steel plates. The welding efficiency is not high and it is time-consuming and labor-intensive. Summary of the Invention

[0006] This application provides a welding device for stainless steel composite steel plates to facilitate the welding of composite steel plates.

[0007] The above-mentioned technical objective of this application is achieved through the following technical solution: A welding device for stainless steel composite steel plates includes a workbench with a fixing clamp for fixing the steel plate, and a first welding structure and a second welding structure above the workbench. The first welding structure and the second welding structure are arranged opposite to each other, and both the first welding structure and the second welding structure are connected to a lifting structure.

[0008] By adopting the above scheme, when welding of the composite plate is required, the two composite plates are fixed with a fixing clamp. Then, the first welding structure and the second welding structure weld the two sides of the composite plate simultaneously. The lifting structure drives the first welding structure and the second welding structure to move on the surface of the composite steel plate, thereby making the welding of the composite steel plate more convenient.

[0009] Optionally, the worktable is rotatably connected to a bidirectional lead screw, one end of which is connected to a lead screw motor. Two fixing clamps are provided, which are threadedly connected to the bidirectional lead screw and are located at both ends of the bidirectional lead screw respectively.

[0010] By adopting the above scheme, the lead screw motor drives the bidirectional lead screw to rotate, thereby causing the two fixing clamps to move away from or closer to each other. This allows the operator to fix the two composite plates with the fixing clamps, and then the lead screw motor drives the bidirectional lead screw to connect the two composite plates, making the connection of the composite plates more convenient.

[0011] Optionally, the fixing clamp includes a connecting seat, a left clamping plate, and a right clamping plate. The connecting seat is connected by a bidirectional screw thread. A clamping plate groove is provided on the upper surface of the connecting seat. The left clamping plate and the right clamping plate are slidably connected in the clamping plate groove. A hand-operated screw is provided in the clamping plate groove. The surface of the hand-operated screw is provided with threads in opposite directions. The left clamping plate and the right clamping plate are threaded to the hand-operated screw, and the left clamping plate and the right clamping plate are located on opposite sides of the hand-operated screw.

[0012] By adopting the above solution, the operator can rotate the screw to adjust the distance between the left and right clamping plates. After placing the composite plate between the left and right clamping plates, the operator can rotate the screw to clamp the composite plate, making the composite plate more secure. After welding, the operator can rotate the screw to loosen the composite plate, making it easy to remove the composite plate.

[0013] Optionally, the lifting structure includes a lifting motor, the output shaft of which is fixedly connected to a first gear, the first gear meshing with a second gear, the second gear being rotatably connected to the worktable, and the center of the second gear having a threaded hole, the second gear being threadedly connected to a threaded rod, and a lifting plate being fixedly connected to one end of the threaded rod. Two lifting plates are provided, and the two lifting plates are respectively connected to the first welding structure and the second welding structure.

[0014] By adopting the above scheme, the lifting motor rotates, driving the first gear to rotate, and the first gear drives the second gear to rotate. Since the second gear is threadedly connected to the threaded rod, when the second gear rotates, the threaded rod moves in the vertical direction, thereby driving the lifting plate to move up and down, and thus driving the first welded structure and the second welded structure to rotate and connect.

[0015] Optionally, the threaded rod has a rectangular groove at its lower end, and a rectangular column is fixedly connected to the worktable. The rectangular column is inserted into the rectangular groove, and the rectangular column is slidably connected to the threaded rod.

[0016] By adopting the above scheme, the rectangular column restricts the rotation of the threaded rod, preventing the threaded rod from rotating together with the second gear and causing transmission failure.

[0017] Optionally, both the first welding structure and the second lifting structure are connected to a telescopic rod. The telescopic rod is rotatably connected to the worktable at its lower end, and a second bevel gear is fixedly connected to the hinge shaft of the telescopic rod and the worktable. The second bevel gear meshes with a first bevel gear, and a receiver / discharger is fixedly connected to the first bevel gear. A placement slot for receiving and placing the first welding structure and the second welding structure is provided on the upper surface of the worktable.

[0018] By adopting the above scheme, the rotation of the retractor drives the first bevel gear to rotate, which in turn drives the second bevel gear to rotate, which in turn drives the telescopic rod to rotate around the hinge axis, thereby driving the first and second welded structures into the placement slot. This allows the first and second welded structures to be retracted when not in use, which not only reduces space occupation but also increases the protection of the first and second welded structures.

[0019] Optionally, the first bevel gear meshes with a third bevel gear, the third bevel gear is fixedly connected to a wheel rod, the wheel rod is rotatably connected to the worktable, a third gear is fixedly connected to the end of the wheel rod away from the third bevel gear, the third gear meshes with a rack, the rack is connected to a cover plate, and the cover plate is slidably connected above the placement slot.

[0020] By adopting the above scheme, when the first gear rotates, it drives the third gear to rotate, which in turn drives the rack to move. The rack then drives the cover plate to move, thereby opening or closing the cover plate. When the first or second welded structure is removed from the placement slot, the cover plate closes, thus reducing the amount of waste material entering the workbench during the welding process. Optionally, the telescopic rod includes an outer tube and an inner tube. The inner tube is connected to the second bevel gear, and the outer tube is sleeved on the outside of the inner tube. The two outer tubes are respectively connected to the first welding structure and the second welding structure. A guide block is fixedly connected to the lower end of the outer tube, and a guide plate is fixedly connected to the worktable. The surface of the guide plate is provided with a vertical guide groove and an arc guide groove. The vertical guide groove and the arc guide groove are connected. When the first welding structure and the second welding structure are located in the placement groove, the guide block slides in the arc guide groove.

[0021] By adopting the above scheme, when the telescopic rod is vertical, the guide block is located in the vertical guide groove. When the telescopic rod extends, the guide block slides out of the vertical guide groove. When it is necessary to place the first welding structure and the second welding structure in the placement groove, the guide block moves along the arc guide groove. The arc guide groove limits the guide block, so that the telescopic rod will not extend during the rotation around the intersection axis.

[0022] Optionally, a sliding groove is provided on the upper surface of the lifting plate, and both the first welding structure and the second welding structure are connected to sliders. When the first welding structure and the second welding structure are located directly above the lifting plate, the sliders slide into the sliding groove.

[0023] By adopting the above scheme, the lifting plate can drive the first welding structure and the second welding structure to rise and fall more smoothly.

[0024] Optionally, this application also discloses a welding method for a welding apparatus for stainless steel composite plates, comprising the following steps: S1. Fix the two composite boards with a fixing clip; S2. Simultaneously activate the lifting structure, the first welding structure, and the second welding structure; S3. Remove the two composite boards from the fixing clips.

[0025] In summary, this application has the following technical effects: 1. By setting a fixing clamp to fix the composite steel plate, and setting a first welding structure and a second welding structure to weld the composite plate at the same time, the welding of the composite plate is made easier. 2. By setting up a bidirectional lead screw and a lead screw motor, the two composite steel plates can be automatically connected, thereby further simplifying the welding process; 3. The placement slots allow the first and second welded structures to be folded up when not in use. Attached Figure Description

Detailed Implementation

[0028] The present application will be further described in detail below with reference to the accompanying drawings.

[0029] Reference Figure 1 A welding device for stainless steel composite plates includes a workbench 1, on which a fixing clamp 2 for fixing the steel plates is provided. A first welding structure 3 and a second welding structure 4 are arranged above the workbench 1, facing each other. Both the first welding structure 3 and the second welding structure 4 are connected to a lifting structure 5. When welding the composite plates is required, the two composite plates are fixed by the fixing clamp 2. Then, the first welding structure 3 and the second welding structure 4 simultaneously weld both sides of the composite plates. The lifting structure 5 moves the first welding structure 3 and the second welding structure 4 on the surface of the composite steel plates, thereby facilitating the welding of the composite steel plates.

[0030] Reference Figure 2 The worktable 1 has an internal cavity with a bidirectional lead screw 6 rotatably connected inside. One end of the bidirectional lead screw 6 is connected to a lead screw motor 61. Two clamps 2 are provided, each threadedly connected to the bidirectional lead screw 6, and are located at opposite ends of the lead screw 6. The upper surface of the worktable 1 has sliding holes for the clamps 2 to move. When composite plate welding is required, the two clamps 2 clamp the two composite plates respectively. Then, the lead screw motor 61 starts, driving the bidirectional lead screw 6 to rotate, thereby bringing the two clamps 2 closer together, and thus bringing the two composite plates closer together, allowing them to automatically align, making the assembly of the composite plates more convenient.

[0031] Reference Figure 1 and Figure 2 The fixing clamp 2 includes a connecting seat 21, a left clamping plate 22 and a right clamping plate 23. The connecting seat 21 has a threaded hole at its lower end and is connected to the bidirectional lead screw 6. A clamping plate groove 211 is provided above the connecting seat 21. The left clamping plate 22 and the right clamping plate 23 are slidably connected in the clamping plate groove 211, and a hand-operated lead screw 212 is rotatably connected in the clamping plate groove 211. The two ends of the hand-operated lead screw 212 are provided with opposite threads. The left clamping plate 22 and the right clamping plate 23 are connected to the hand-operated lead screw 212 through threads, and the left clamping plate 22 and the right clamping plate 23 are respectively provided at both ends of the hand-operated lead screw 212, and a handle is connected to one end of the hand-operated lead screw 212. When it is necessary to use clamps to hold the composite board, turn the handle to drive the hand screw 212 to rotate, thereby causing the left clamp 22 and the right clamp 23 to move away from each other. Then place the composite board between the left clamp 22 and the right clamp 23, turn the handle to bring the left clamp 22 and the right clamp 23 closer together, thereby clamping the composite board tightly with the left clamp 22 and the right clamp 23.

[0032] Reference Figure 3The lifting structure 5 is provided in two sets. The two sets of lifting structures 5 are respectively connected to the first welding structure 3 and the second welding structure 4. The lifting structure 5 includes a lifting motor 51, a second gear 52 and a threaded rod 53. The lifting motor 51 is fixedly connected to the cavity. The output shaft of the lifting motor 51 is fixedly connected to the first gear 511. The second gear 52 is rotatably connected to the transmission cavity. The first gear 511 and the second gear 52 mesh. A threaded hole is opened in the middle of the second gear 52. The threaded rod 53 passes through the threaded hole and is threadedly connected to the second gear 52. The end of the threaded rod 53 away from the second gear 52 passes through the worktable 1 and is fixedly connected to the lifting plate 531. A sliding groove is opened on the surface of the lifting plate 531. A slider is slidably connected in the sliding groove. Since there are two sets of lifting structures 5, there are also two sliders. The two sliders are respectively fixedly connected to the first welding structure 3 and the second welding structure 4. When welding the composite plate, the lifting motor 51 rotates, driving the first gear 511 to rotate the rod, which in turn drives the second gear 52 to rotate. Since the second gear 52 is threadedly connected to the threaded rod 53, the threaded rod 53 moves vertically when the second gear 52 rotates, thereby realizing the lifting of the first welding structure 3 and the second welding structure 4.

[0033] Reference Figure 3 and Figure 4 Both the first welding structure 3 and the second welding structure 4 are connected to telescopic rods 7. Each telescopic rod 7 includes an inner rod and an outer tube 72. The outer tube 72 is sleeved on the outside of the inner rod. The two outer tubes 72 are fixedly connected to the first welding structure 3 and the second welding structure 4, respectively. The inner rod is rotatably connected to the worktable 1, and a second bevel gear 711 is fixedly connected to one end of the hinge shaft of the inner rod. The second bevel gear 711 meshes with a first bevel gear 712, and the first bevel gear 712 is fixedly connected to a receiver / discharger 713. The receiver / discharger 713 is fixedly connected to the worktable 1. A placement slot 11 is provided on the upper surface of the worktable 1. The drive motor rotates, causing the first bevel gear 712 to rotate, which in turn drives the second bevel gear 711 to rotate, thereby causing the inner rod to rotate around the hinge shaft. This moves the first welding structure 3 and the second welding structure 4 into the placement slot 11, protecting them and reducing the footprint of the welding device. Furthermore, since the movement paths of the first welding structure 3 and the second welding structure 4 are arc-shaped, the lifting plate 531 and the sliding groove are also arc-shaped.

[0034] Reference Figure 4 and Figure 5A guide plate 9 is provided inside the cavity. The surface of the guide plate 9 is provided with a vertical guide groove 91 and an arc guide groove 92. A guide block 721 is fixedly connected to the lower end of the outer rod. When the telescopic rod 7 retracts, the guide block 721 slides into the vertical groove. When the first welding structure 3 and the second welding structure 4 move into the placement groove 11, the guide block 721 slides in the arc guide groove 92, so that the arc guide groove 92 restricts the guide block 721, thereby preventing the telescopic rod 7 from extending out during the process of the first welding structure 3 and the second welding structure 4 being retracted into the placement groove 11.

[0035] Reference Figure 4 and Figure 5 A cover plate 8 is provided at the opening of the placement groove 11. The cover plate 8 is slidably connected to the worktable 1. A rack 81 is fixedly connected to the cover plate 8. The rack 81 meshes with a third gear 82. The third gear 82 is fixedly connected to a wheel rod 83. The wheel rod 83 is rotatably connected to the worktable 1. A third bevel gear 84 is fixedly connected to the end of the wheel rod 83 away from the third gear 82. The third bevel gear 84 meshes with a first bevel gear 712. Thus, when the first bevel gear 712 rotates, the third bevel gear 84 rotates, driving the third gear 82 to rotate, thereby driving the rack 81 to move, which in turn drives the cover plate 8 to open or close. Thus, when the first welding structure 3 and the second welding structure 4 are removed from the placement groove 11, the cover plate 8 covers the placement groove 11, thereby preventing welding waste from falling into the placement groove 11.

[0036] The specific implementation principle of this application is as follows: When welding composite steel is required, the operator first clamps the composite plate with clamps, then rotates the handle to drive the hand-operated screw 212 to rotate, thereby causing the left clamp 22 and the right clamp 23 to move away from each other. Then, the composite plate is placed between the left clamp 22 and the right clamp 23, and the handle is rotated to bring the left clamp 22 and the right clamp 23 closer together, thus clamping the composite plate tightly. Subsequently, the screw motor rotates, driving the bidirectional screw 6 to rotate, thereby bringing the two fixed clamps 2 closer together, thus bringing the two composite plates closer together, causing the two composite plates to automatically align; subsequently... The subsequent rotation of the discharge motor 713 drives the first bevel gear 712 to rotate, which in turn drives the second bevel gear 711 to rotate. This causes the first welding structure 3 and the second welding structure 4 to move out of the placement groove 11 and align with the area of ​​the composite plate to be welded. At this time, the slider slides into the groove. Simultaneously, the first bevel gear 712 drives the third bevel gear 84 to rotate, thereby closing the cover plate 8 to prevent waste from falling into the placement groove 11. Then, the lifting motor 51 starts, driving the first gear 511 to rotate, which in turn drives the second gear 52 to rotate, thereby driving the threaded rod 53 to rise and fall, thus welding the joint of the composite plate. This application greatly reduces the welding difficulty of the composite plate by simultaneously welding both sides of the composite plate and fixing the composite plate with the fixing clamp 2, making the welding of the composite plate more convenient.

[0037] Optionally, this application also discloses a welding method for a welding apparatus for stainless steel composite plates, comprising the following steps: S1. Fix the two composite boards with fixing clip 2; S2. Simultaneously activate lifting structure 5, first welding structure 3, and second welding structure 4; S3. Remove the two composite boards from the fixing clip 2.

[0038] This specific embodiment is merely an explanation of this application and is not intended to limit it. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but such modifications are protected by patent law as long as they fall within the scope of the claims of this application.
