Description

Technical Field

[0001] This utility model relates to the field of seam welding technology, specifically a welding equipment for sheet metal processing. Background Technology

[0002] Sheet metal parts are products manufactured using sheet metal processing techniques, and they are indispensable in our daily lives. Sheet metal parts are made through laser cutting, heavy-duty machining, metal bonding, metal drawing, plasma cutting, precision welding, roll forming, sheet metal bending, die forging, and water jet cutting.

[0003] Commonly available welding equipment for the intersection of box side walls typically places the box on a workbench, where a baffle limits its position. A linear module then moves the welding torch up and down to weld the box. However, during welding, the two adjacent side walls may be asymmetrical or not perpendicular to each other. Welding under these conditions can lead to non-perpendicular side walls, resulting in defective products and significant waste. Utility Model Content

[0004] The purpose of this utility model is to provide a welding device for sheet metal processing to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a welding device for sheet metal processing, comprising:

[0006] A workbench, on one side of which a linear module is fixed, and a welding gun is provided on the sliding part of the linear module. Two mutually perpendicular baffles are fixed on the top of the workbench, and a welding joint is provided at the intersection of the two baffles.

[0007] Two support plates are fixed to the top of two baffles respectively, and a top plate is fixed between the two support plates. A pressing mechanism is fixed to the bottom of the top plate. The pressing mechanism can press the bottom and side walls of the box to prevent the box from moving during welding, and also ensure that the side walls of the box remain perpendicular to each other.

[0008] Preferably, both of the two electric push rods are equipped with clamps at their telescopic ends, and quick-release mechanisms are provided between the two clamps and the two electric push rods. The clamps facilitate better support for the side walls of the housing, and the quick-release mechanisms facilitate quick replacement of the clamps according to the different heights of the side walls of the housing.

[0009] Preferably, the pressing mechanism includes an electric push rod one fixed to the bottom of the top plate, a pressure block fixed to the telescopic end of the electric push rod one, and electric push rod two fixed to both sides of the pressure block facing the baffle. The pressure block presses the bottom of the box, and the clamping plate cooperates with the baffle to press the side wall of the box.

[0010] Preferably, the quick-release mechanism includes a fixing block fixed to the output end of the electric push rod, an insert block on the side of the fixing block facing the clamping plate, the insert block being fixedly connected to the clamping plate, and a slot on the side of the fixing block facing the insert block, the insert block being able to be inserted into the slot to facilitate quick assembly and disassembly of the clamping plate.

[0011] Preferably, the fixing block has a pressing groove on both sides, and a pressing block is provided inside each of the two pressing grooves. The insert block has a limiting groove on both sides, and a spring is provided inside each of the two limiting grooves. A limiting block is fixed to the opposite side of each of the two springs. The limiting block, in conjunction with the spring, can limit the fixing block and the insert block.

[0012] Preferably, a sliding block is fixed inside each of the two pressing slots, and a sliding slot is formed on each of the two pressing blocks. The sliding block matches the sliding slot to prevent the pressing block from falling out of the pressing slot.

[0013] Preferably, the two limiting blocks are arranged with inclined surfaces facing the pressing block, and the inclined surfaces face the fixing block, so as to facilitate pushing the insert block into the slot.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. By setting up a clamping mechanism, the pressure block presses against the bottom of the box, while the clamping plate presses against the side walls of the box, so that the two adjacent side walls to be welded are perpendicular to each other, which facilitates the subsequent welding work and can improve the perpendicularity of the two adjacent side walls to be welded.

[0016] 2. The quick-release mechanism allows for rapid assembly and disassembly of the clamping plates, facilitating the replacement of clamping plates for boxes with different side wall heights, thereby increasing the speed of clamping plate replacement and improving welding efficiency.

Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figures 1 to 5 One embodiment of this utility model provides: a welding device for sheet metal processing, comprising:

[0025] Workbench 5, with a linear module 1 fixed on one side of the workbench 5. A welding gun 2 is installed on the sliding part of the linear module 1. Two mutually perpendicular baffles 6 are fixed on the top of the workbench 5. A welding port is provided at the intersection of the two baffles 6. The linear module 1 drives the lead screw through the motor. The lead screw drives the slider to move up and down. The slider drives the welding gun 2 to move up and down to weld the right angle of the box.

[0026] Two support plates 4 are fixed to the top of two baffles 6 respectively. A top plate 3 is fixed between the two support plates 4. A pressing mechanism is fixed at the bottom of the top plate 3. The pressing mechanism can press the bottom and side walls of the box to prevent the box from moving during welding, and also ensure that the side walls of the box can remain perpendicular to each other.

[0027] Furthermore, both of the two electric push rods are equipped with clamps at their telescopic ends, and quick-release mechanisms are provided between the two clamps and the two electric push rods. The clamps 10 facilitate better support for the side wall of the box, and the quick-release mechanisms facilitate quick replacement of the clamps 10 according to the different heights of the side wall of the box.

[0028] Furthermore, the clamping mechanism includes an electric push rod 8 fixed to the bottom of the top plate 3. A pressure block 9 is fixed to the telescopic end of the electric push rod 8. Electric push rods 7 are fixed to both sides of the pressure block 9 facing the baffle 6. The pressure block 9 clamps the bottom of the box. The clamping plate 10, together with the baffle 6, clamps the side walls of the box. The electric push rod 8 drives the pressure block 9 to move downward, which, together with the worktable 5, clamps the box to prevent it from moving during welding and causing it to be scrapped. At the same time, the electric push rods 7 on both sides of the pressure block 9 will drive the clamping plate 10 to move. The clamping plate 10, together with the baffle 6, will clamp the side walls of the box, so that the two adjacent side walls of the box remain perpendicular to each other, which is convenient for subsequent welding work and can reduce the defect rate of the box welding.

[0029] Furthermore, the quick-release mechanism includes a fixing block 11 fixed to the output end of the electric push rod 7. The fixing block 11 has an insert 14 on the side facing the clamping plate 10, which is fixedly connected to the clamping plate 10. A slot 13 is opened on the side of the fixing block 11 facing the insert 14, allowing the insert 14 to be inserted into the slot 13. Both sides of the fixing block 11 have push grooves 20, each containing a push block 12. Both sides of the insert 14 have limit grooves 16, each containing a spring 15. Limit blocks 17 are fixed to the opposite sides of the two springs 15. In the normal state, the end of the limit block 17 connected to the spring 15 is located inside the limit groove 16. Therefore, the limit block 17 is in a limited position and will not fall out of the limit groove 16. The elastic coefficient of the spring 15 can be selected by those skilled in the art based on actual conditions. The limit block 17, in conjunction with the spring 15, can control the fixing block 11. The insertion block 14 is positioned and aligned with the slot 13. The limiting block 17, under the pressure of the fixing block 11, enters the limiting groove 16. Simultaneously, the limiting block 17 compresses the spring 15. When the limiting block 17 aligns with the pressing groove 20, it enters the pressing groove 20 under the action of the spring 15. At the same time, the limiting block 17 pushes the pressing block 12 to move. At this point, the fixing block 11 and... The insert blocks 14 mutually limit each other, thereby completing the quick installation of the clamp plate 10. When it is necessary to disassemble the clamp plate 10, first press the push blocks 12 on both sides of the fixing block 11, so that the push blocks 12 push the limiting block 17 out of the push groove 20. At the same time, the limiting block 17 will squeeze the spring 15. When the limiting block 17 is completely pressed into the limiting groove 16 by the push blocks 12, the insert block 14 can be pulled out from the slot 13 inside the fixing block 11, thereby completing the quick disassembly of the clamp plate 10.

[0030] Furthermore, each of the two pressing slots 20 has a sliding block 19 fixed inside, and each of the two pressing blocks 12 has a sliding groove 18. The sliding block 19 matches the sliding groove 18. When the pressing block 12 is pressed, the pressing block 12 will slide in the pressing slot 20. At this time, the slider will slide inside the sliding groove 18 to prevent the pressing block 12 from falling out of the pressing slot 20.

[0031] Furthermore, the two limiting blocks 17 are inclined on the side facing the pressing block 12, with the inclined surface facing the fixing block 11, which facilitates pushing the insert block 14 into the slot 13. The spring 15 is in the normal state, with the inclined surface corresponding to the side wall of the limiting groove 16. When the inclined surface of the limiting block 17 contacts the fixing block 11, as the insert block 14 is continuously pushed in, the inclined surface of the limiting block 17 will be squeezed by the fixing block 11 and slide inside the limiting groove 16, so that the limiting block 17 enters the limiting groove 16, which makes it easier to insert the insert block 14 into the slot 13 without having to press the limiting block 17 into the limiting groove 16 by hand, which is more convenient.

[0032] During operation, the box is first placed on the workbench 5, and the corner of the box is placed into the notch of the two baffles 6. The electric push rod 8 is turned on, and the electric push rod 8 drives the pressure block 9 to move downward, which works with the workbench 5 to press the box tightly, preventing the box from moving during welding and causing it to be scrapped. At the same time, the electric push rods 7 on both sides of the pressure block 9 will drive the clamping plate 10 to move. The clamping plate 10 will work with the baffles 6 to press the side wall of the box, so that the two adjacent side walls of the box are perpendicular to each other, which is convenient for subsequent welding work. Then, the linear module 1 is turned on, which drives the welding gun 2 to move up and down to weld the corner of the box.

[0033] When the side walls of the box are not of uniform height, and the clamping plate 10 needs to be replaced according to the height of the side walls, first press the push blocks 12 on both sides of the fixing block 11, so that the push blocks 12 push the limiting block 17 out of the push groove 20. At the same time, the limiting block 17 will compress the spring 15. When the limiting block 17 is completely pressed into the limiting groove 16 by the push blocks 12, the insert block 14 can be pulled out from the slot 13 inside the fixing block 11, thus completing the quick disassembly of the clamping plate 10. Then, the new clamping plate 10 can be installed. Insert block 14 is aligned with slot 13 and inserted. Limiting block 17 will enter the limiting groove 16 under the pressure of fixing block 11. At the same time, limiting block 17 will press spring 15. When limiting block 17 is aligned with pressing groove 20, limiting block 17 will enter the pressing groove 20 under the action of spring 15. At the same time, limiting block 17 will push pressing block 12 to move. At this time, under the obstruction of limiting block 17, fixing block 11 and insert block 14 are mutually limited, thereby completing the quick installation of clamp 10.

[0034] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
