Description

Technical Field

[0001] This utility model relates to the field of sheet metal processing technology, and in particular to a welding precision positioning device for sheet metal processing. Background Technology

[0002] Sheet metal processing is a comprehensive cold working process specifically for thin metal sheets, encompassing various methods such as shearing, stamping, bending, welding, and riveting. Its most significant characteristic is that the thickness of the same part remains consistent throughout. Sheet metal parts, as widely used metal components today, offer numerous advantages. On one hand, they are very easy to form, have extremely high processing efficiency, and are relatively inexpensive. In the processing of sheet metal parts, multiple sheet metal parts often need to be welded together. Welding, as an important processing and fixing method, has been widely applied. Furthermore, during welding operations, precise positioning of the sheet metal parts is essential to ensure the quality and accuracy of the weld.

[0003] Welding positioning devices typically consist of the following components: a fixed base, the fundamental support of the entire device, generally made of sturdy metal to ensure stability during welding, preventing shaking or displacement; clamps, common clamping components that use mechanical structures or hydraulic / pneumatic systems to clamp sheet metal parts; positioning blocks, used to determine the position of the sheet metal parts, usually with precise dimensions and shapes; an adjustment device, typically equipped with an adjustment mechanism to accommodate sheet metal parts of different sizes and shapes; and positioning pins and holes, crucial structures for accurately determining the relative positions of the sheet metal parts. Before welding, the positioning holes on the sheet metal parts are aligned with the positioning pins on the device to ensure accurate positional relationships between the sheet metal parts. Positioning pins typically possess high precision and hardness to guarantee accurate and stable positioning. The support structure can be adjusted according to the shape of the sheet metal parts, providing stable support and preventing deformation during welding.

[0004] Existing welding equipment requires repeated disassembly and reassembly of sheet metal parts when welding different positions. This repeated disassembly and reassembly can easily lead to small errors in the sheet metal parts at each stage. The accumulated errors seriously affect the welding accuracy of the sheet metal parts. Furthermore, it has limited adaptability to sheet metal parts of different shapes, and may be difficult to achieve accurate positioning for sheet metal parts with complex or special shapes. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a precision welding positioning device for sheet metal processing, which aims to improve the problems of accumulated errors and poor adaptability to positioning of special sheet metal parts in the existing sheet metal welding process.

A worm 6 is meshed with the outer side of the worm gear 5. A rotating disk 10 is fixedly connected to the front of the outer side of the worm 6. After the sheet metal parts are fixed, the worker performs edge welding between the sheet metal parts. To prevent position adjustment during sheet metal welding, the worker drives the worm 6 through the rotating disk 10, which causes the worm gear 5 to drive the welding table 9 on the connecting column 7 to adjust the angle, so that the welding angle can be adjusted according to the welding worker's comfort.

[0030] Reference Figures 3-6 A column 15 is rotatably connected to the top of the mounting base 11. A clamping seat 16 is slidably connected to the outside of the column 15. A clamping block 17 is provided on the right side of the front end of the clamping seat 16. A fixing bolt 20 is provided on the right side of the top of the clamping seat 16. An angle shaft 19 is rotatably connected to the inner side of the right end of the clamping seat 16. A positioning seat 21 is fixedly connected to the bottom side of the rear of the right end of the angle shaft 19. A clamping frame 29 is fixedly connected to the right side of the top of the angle shaft 19. A limit post 30 is fixedly connected to the top center of the inner side of the clamping frame 29. A clamping spring 23 is sleeved on the outside of the limit post 30. A lever buckle 24 is slidably connected to the outside of the limit post 30. A positioning block 22 is fixedly connected to the right end of 24. The height of the clamping seat 16 is adjusted according to the welding position between the sheet metal parts. When the position is adjusted to a suitable position, the clamping bolt 18 is used to fix the position of the clamping seat 16. The positioning seat 21 and the positioning block 22 on the angle shaft 19 cooperate to clamp and fix the sheet metal parts. The clamping spring 23 in the clamping frame 29 pushes the positioning block 22 on the limit post 30 to clamp the sheet metal parts on the positioning seat 21. Then, the angle of the sheet metal parts is adjusted by the angle shaft 19. Then, the angle of the angle shaft 19 is fixed by the fixing bolt 20.

[0031] Reference Figures 1-6A dust cover 8 is fixedly connected to the top inner side of the equipment frame 1. Mounting blocks 25 are fixedly connected to the front and rear bottom of the mounting base 11. A fastening block 27 is slidably connected to the middle outer side of the mounting block 25. A fastening wedge 26 is slidably connected to the bottom inner side of the mounting block 25. A fastening bolt 28 is threaded between the mounting block 25 and the fastening wedge 26. The mounting base 11 and the column 15 are fixedly connected by a rotating pin 12. Clamping bolts 18 are threadedly connected to the middle of the left and right ends of the clamping seat 16 and the clamping block 17. The bottom inner side of the column 15 is slidably connected by a fastening wedge 26. The moving connection is provided with a positioning pin 13, and a positioning spring 14 is fixedly connected to the middle of the top of the positioning pin 13. The worker inserts the mounting block 25 on the mounting base 11 into the mounting hole of the welding table 9, and then uses a hex wrench to tighten the fastening bolt 28, so that the fastening wedge 26 in the mounting block 25 is pushed outward by the fastening block 27, so that the mounting base 11 is firmly fixed on the welding table 9. The dust cover 8 on the equipment frame 1 can block the flux generated during welding and prevent it from entering the equipment frame 1 and affecting the operation of the internal mechanism.

[0032] Working principle: The worker inserts the mounting block 25 on the mounting base 11 into the mounting hole of the welding table 9, and then uses a hex wrench to tighten the fastening bolt 28. This causes the fastening wedge 26 inside the mounting block 25 to be pushed outward by the fastening block 27, thus firmly fixing the mounting base 11 onto the welding table 9. At the same time, the height of the clamping seat 16 is adjusted according to the welding position between the sheet metal parts. When the appropriate position is reached, the clamping bolt 18 is used to fix the position of the clamping seat 16. The positioning seat 21 and positioning block 22 on the angle shaft 19 cooperate to clamp and fix the sheet metal parts. The clamping spring 23 inside the clamping frame 29 is at the limit post 3. The positioning block 22 is pushed to clamp the sheet metal part onto the positioning seat 21. Then, the angle of the sheet metal part is adjusted by the angle shaft 19. Subsequently, the angle shaft 19 is fixed by the fixing bolt 20. After the sheet metal part is fixed, the worker performs edge welding between the sheet metal parts. In order to prevent the position adjustment of the sheet metal part during welding, the worker drives the worm gear 6 by rotating the disk 10, which causes the worm wheel 5 to drive the welding table 9 on the connecting column 7 to adjust the angle. This allows the welding angle to be adjusted according to the welding worker's comfort. At the same time, the dust cover 8 on the equipment frame 1 can block the slag generated during welding and prevent it from entering the equipment frame 1 and affecting the operation of the internal mechanism.
