Abstract
Description
Technical Field
[0001] This utility model relates to the field of sheet metal processing technology, and in particular to a welding device for sheet metal processing. Background Technology
[0002] Sheet metal is a general term for thin sheet metal materials in the field of metal processing, usually referring to steel plates, aluminum plates, copper plates, etc. Its processing mainly involves shearing, stamping, bending, stretching, forming and other processes to process flat materials into parts or structural components of various shapes. Sheet metal welding is the process of connecting multiple sheet metal parts into a whole through heat or pressure.
[0003] A search revealed that Chinese patent CN220838667U discloses a sheet metal welding positioning device. This device addresses the issue that using a positioning plate to limit the movement of sheet metal requires changing different positioning plates for different sizes of sheet metal, increasing workload and reducing efficiency. Instead, a fixed plate and a rotating plate are used to restrict the sliding rods, allowing adjustment of the relative distance between the rods. This enables the device to accommodate and position sheet metal bodies of various sizes, simplifying the clamping process and reducing worker workload.
[0004] The aforementioned sheet metal welding is only suitable for welding circular tubular shapes. It is not convenient to position right-angle welds. In the existing technology, it is common to weld two sheet metal plates at right angles. However, when welding two sheet metal plates at right angles, it is not convenient to position and fix the longitudinal and transverse plates. As a result, the operator needs to manually hold the welded transverse or longitudinal plates, which can easily cause the transverse or longitudinal plates to shift or become misaligned during right-angle welding, making it difficult to weld normally and reducing the welding quality. Utility Model Content
[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a welding device for sheet metal processing.

A sliding sleeve is fixedly connected to one side of the second stepper motor. A guide rod is fixedly connected to the other side of the welding table. The sliding sleeve is slidably connected to the outside of the guide rod.
[0014] As a further description of the above technical solution:
[0015] The lead screw is externally threaded with a movable block, which is slidably connected inside the mounting housing. A second hydraulic cylinder is fixedly connected to one side of the movable block.
[0016] As a further description of the above technical solution:

[0034] The clamping assembly includes a connecting frame 5, which is fixedly connected to the output end of the first hydraulic cylinder 4. A fixing shell 6 is fixedly connected to one side of the connecting frame 5 and one side of the welding table 1. A bidirectional stud 7 is rotatably connected inside the fixing shell 6, and the outside has threads in the opposite direction.
[0035] As attached Figure 5 As shown, the fixed housing 6 has two sliding connections inside, and the sliding frame 8 has a threaded groove 9 inside, which matches the thread on the outside of the bidirectional stud 7. The bidirectional stud 7 is threaded into the inside of two of the threaded grooves 9. One end of the sliding frame 8 is fixedly connected to a clamping plate 10, which facilitates clamping the sheet metal plate.
[0036] As attached Figure 4 As shown, a first stepper motor 11 is fixedly installed on one side of the fixed housing 6. Gears 12 are fixedly connected to the output end of the first stepper motor 11 and the middle part of the bidirectional stud 7. The two gears 12 are meshed and connected to transmit the rotational power to the bidirectional stud 7, which drives it to rotate.
[0037] As attached Figure 6 As shown, a mounting shell 13 is fixedly connected to one end of the connecting frame 5, a second stepper motor 14 is fixedly installed on one side of the mounting shell 13, a lead screw 15 is fixedly connected to the output end of the second stepper motor 14, and a sliding sleeve 16 is fixedly connected to one side of the second stepper motor 14 for sliding outside the guide rod 17, thereby improving the stability of the installation of the second stepper motor 14.
[0038] As attached Figure 2As shown, a guide rod 17 is fixedly connected to the other side of the welding table 1. A sliding sleeve 16 is slidably connected to the outside of the guide rod 17 to improve the stability of the mounting shell 13 when it moves. A moving block 18 is threadedly connected to the outside of the lead screw 15 to facilitate the lateral movement of the moving block 18. The moving block 18 is slidably connected to the inside of the mounting shell 13, and the mounting shell 13 limits the movement of the moving block 18. A second hydraulic cylinder 19 is fixedly connected to one side of the moving block 18.
[0039] As attached Figure 7 As shown, the output end of the second hydraulic cylinder 19 is provided with an installation assembly, which includes an installation sleeve 20 for mounting the welding machine 2. The installation sleeve 20 is fixedly connected to the output end of the second hydraulic cylinder 19, which facilitates the lateral movement of the installation sleeve 20. The installation sleeve 20 is located outside the welding machine 2. Threaded sleeves 21 are connected through both sides of the installation sleeve 20 for mounting bolts 22. Bolts 22 are threaded inside the threaded sleeves 21, which facilitates clamping the welding machine 2. A limit frame 23 is fixedly connected to the upper surface of the installation sleeve 20. A guide sleeve 25 is fixedly connected to one end of the limit frame 23. A fixed rod 24 is fixedly connected to the upper surface of the moving block 18, which guides the guide sleeve 25. The guide sleeve 25 is slidably connected to the outside of the fixed rod 24, which improves the stability of the installation sleeve 20 during lateral movement.
[0040] Working principle: In use, the longitudinal sheet metal plate is first placed between the two bottom clamping plates 10, and the transverse sheet metal plate is placed between the two side clamping plates 10. When clamping the sheet metal plate, the controller drives the first stepper motor 11, which drives the gear 12 to rotate. Under the action of the two gears 12 meshing with each other, the gear 12 in the middle of the double-direction stud 7 rotates, which in turn drives the double-direction stud 7 to rotate. When the double-direction stud 7 rotates, it drives the two moving frames 8 on both sides to slide closer to each other inside the fixed shell 6 through the threaded groove 9, so that the two clamping plates 10 on both sides move closer to each other. This makes the two bottom clamping plates 10 clamp the longitudinal sheet metal plate and the two side clamping plates 10 clamp the transverse sheet metal plate. Then, the first hydraulic cylinder 4 is activated, and when its output end drives the connecting frame 5 to move down, it is easy for the connecting frame 5 to drive the fixed shell 6 on the side to move down, which in turn indirectly drives the transverse sheet metal plate clamped on the side to move down, so that the edges of the transverse sheet metal plate and the longitudinal sheet metal plate are in contact and on the same horizontal line, which is convenient for welding.
[0041] As the connecting frame 5 moves down, it will drive the mounting shell 13 to move down, and then indirectly drive the welding machine 2 to move down along with the horizontal sheet metal plate through the moving block 18. The welding head of the welding machine 2 is aligned with the bottom of the welding side of the horizontal sheet metal plate. Then the second hydraulic cylinder 19 is opened, and when its output end extends, it drives the welding machine 2 to approach the edge of the horizontal and vertical sheet metal plates to perform welding.
[0042] When disassembling the welding machine 2, loosen the bolt 22 from the inside of the threaded sleeve 21 so that one end of the bolt 22 is inside the threaded sleeve 21, and then slide the welding machine 2 out from the inside of the mounting sleeve 20.
[0043] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
