Description

Technical Field

[0001] The utility model relates to the field of welding jigs, in particular to a high-precision laser welding positioning jig. Background Art

[0002] High-precision laser welding is a welding technology that uses a laser beam with a high energy density to locally heat materials, causing them to quickly melt and form weld seams. The laser beam can be precisely controlled, and the diameter of the focused light spot is very small, enabling very precise control of the welding position and size. During the welding process, by fixing the materials, it can ensure that the position of the joint during welding is accurate, which is particularly important for high-precision welding, such as high-precision laser welding and electronic component welding. Therefore, positioning jigs are required.

[0003] When the existing positioning jigs for laser welding fix materials, they usually place the materials in a fixed groove for welding. The groove can provide precise positioning for the materials, ensuring that the welding joints are in the predetermined positions, which helps to maintain the consistency and quality of welding. However, when using this method, materials with different sizes cannot be clamped and fixed. If materials with different sizes cannot be clamped and fixed, the workpiece will move during the welding process, resulting in inaccurate welding positioning and affecting the welding quality. Unstable or moving workpieces will cause defects in the welding joints, such as uneven weld seams, incomplete penetration, overwelding, or welding cracks, etc. Frequent adjustment and repositioning of the workpiece are required, which will increase the preparation time before welding and reduce the overall production efficiency.

[0023] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0024] Refer to Figure 1 、 Figure 2 and Figure 5, an embodiment provided by the present utility model: a high-precision laser welding positioning fixture, which includes a workbench 1 and a cylinder 11. The output end of the cylinder 11 is fixedly connected with a push plate 12. Four sides of the upper part of the push plate 12 are fixedly connected with support rods 13. The upper part of the support rod 13 is fixedly connected with a connection block 23. Both outer sides of the connection block 23 are rotatably connected with adjusting rods 24. The opposite sides of the two adjusting rods 24 are rotatably connected with movable support rods 16. One end of the movable support rod 16 is fixedly connected with a positioning plate 17. The upper parts of multiple positioning plates 17 are fixedly connected with mounting plates 18. The upper parts of the mounting plates 18 are fixedly connected with electric push rods 19. The output ends of multiple electric push rods 19 are fixedly connected with pressing plates 20. The upper part of the workbench 1 is rotatably connected with a frustum 14. The upper part of the frustum 14 is fixedly connected with a supporting plate 22. Both sides of the upper parts of multiple pressing plates 20 are fixedly connected with limiting columns 21. The limiting columns 21 are slidably connected inside the mounting plates 18. Four sides of the upper part of the frustum 14 are fixedly connected with positioning seats 15. The movable support rods 16 are rotatably connected inside multiple positioning seats 15. The support rods 13 are slidably connected inside the frustum 14.

[0025] First, the operator needs to place the material to be processed on the surface of the supporting plate 22 located above. Subsequently, the operator needs to start the cylinder 11. After the cylinder 11 is started, its output end will start to push the push plate 12 to move along a predetermined trajectory. As the push plate 12 moves, it will drive the support rod 13 to move along the corresponding direction. The movement of the support rod 13 will further drive the connection block 23 to move vertically upward. During the upward movement of the connection block 23, it will further drive the adjusting rod 24 to perform a rotational movement. During the rotation of the adjusting rod 24, it will cause the movable support rod 16 to rotate precisely inside the positioning seat 15. The rotation of the movable support rod 16 will cause multiple positioning plates 17 to approach each other, thereby forming a compact clamping structure. When all the positioning plates 17 are closely adjacent to each other, the operator needs to start the electric push rod 19. After the electric push rod 19 is started, its output end will push the pressing plate 20 to move downward. During the downward movement of the pressing plate 20, it will drive the limiting column 21 to slide smoothly inside the mounting plate 18. Under the combined action of multiple pressing plates 20, the material will be firmly fixed on the upper part of the supporting plate 22. Through such a clamping and fixing mechanism, it can effectively ensure that the material remains in the correct position and angle during the processing.

[0026] Refer to Figure 3 and Figure 4, a motor 2 is fixedly connected to the right part of the workbench 1, the output end of the motor 2 is fixedly connected to a driving gear 3, the upper part of the driving gear 3 is meshed with a circular rack plate 6, a disc 7 is fixedly connected inside the circular rack plate 6, a limiting component is fixedly connected to the outside of the disc 7, the limiting component is used for limiting the disc 7, a cylinder 11 is fixedly connected to the upper part of the disc 7, the limiting component includes pulleys 9, a plurality of pulleys 9 are fixedly connected to the outside of the disc 7, the pulleys 9 are slidably connected inside a slide rail 10, a fixed ring 8 is fixedly connected inside the workbench 1, a slide rail 10 is provided inside the fixed ring 8, a fixed shaft 5 is fixedly connected inside the workbench 1, a driven gear 4 is rotatably connected to the outside of the fixed shaft 5, and the upper part of the driven gear 4 is meshed with the circular rack plate 6.

[0027] During the welding operation, first, the motor 2 needs to be started. The output end of the motor 2 is connected to the driving gear 3, so that the driving gear 3 starts to rotate. As the driving gear 3 rotates, it drives the circular rack plate 6 meshed with it to rotate. During the rotation of the circular rack plate 6, it further drives the driven gear 4 to rotate around the fixed shaft 5. This interaction between the driving gear 3 and the driven gear 4 not only enables the circular rack plate 6 to effectively transmit power, but also ensures that the disc 7 rotates accordingly. The rotation of the disc 7 drives the pulleys 9 to smoothly move along the track inside the slide rail 10. The movement of the pulleys 9 further pushes the rotation of the cylinder 11 and the push plate 12. The rotation of the push plate 12 causes the turntable 14 to start rotating, and the rotation of the turntable 14 can drive the materials on the upper part of the support plate 22 to rotate continuously.

[0028] Working principle: First, place the material on the upper part of the pallet 22. Then, start the cylinder 11. The output end of the cylinder 11 pushes the push plate 12 to move. When the push plate 12 moves, it drives the support rod 13 to move. The support rod 13 drives the connecting block 23 to move upward. When the connecting block 23 moves, it drives the adjusting rod 24 to rotate. The rotation of the adjusting rod 24 drives the movable support rod 16 to rotate inside the positioning seat 15. The rotation of the movable support rod 16 drives multiple positioning plates 17 to approach each other. After the positioning plates 17 approach each other, start the electric push rod 19. The output end of the electric push rod 19 pushes the pressing plate 20 to move downward. The movement of the pressing plate 20 drives the limiting column 21 to slide inside the mounting plate 18. Under the action of multiple pressing plates 20, the material is fixed on the upper part of the pallet 22, achieving effective clamping and fixing of materials with different dimensions, ensuring that the material maintains the correct position and angle during the processing, reducing the time for repeated positioning of the material during the processing, and improving the production efficiency. During the welding process, the motor 2 can be started. The output end of the motor 2 drives the driving gear 3 to rotate. The rotation of the driving gear 3 drives the circular rack plate 6 to rotate. When the circular rack plate 6 rotates, it drives the driven gear 4 to rotate outside the fixed shaft 5. Under the action of the driving gear 3 and the driven gear 4, the circular rack plate 6 drives the disc 7 to rotate. The disc 7 drives the pulley 9 to slide inside the slide rail 10, thereby driving the cylinder 11 and the push plate 12 to rotate, causing the push plate 12 to drive the conical platform 14 to rotate. The rotation of the conical platform 14 can drive the material on the upper part of the pallet 22 to rotate, achieving effective rotation of the material, facilitating multi-position welding operations, adapting to workpieces with different dimensions and shapes, and improving the flexibility of production.
