[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0032] Reference Figures 1 to 3 The utility model provides an embodiment: a positioning assembly for laser welding for precision metal parts processing, comprising a box body 1. A transmission shaft 2 is slidably connected to the top of the box body 1. Through this sliding connection, the transmission shaft 2 can move smoothly on the top of the box body 1, thereby providing flexible transmission support for the movement of subsequent related components, making the linkage of the various components of the entire device more coordinated. An operating table 3 is fixedly connected to the top of the transmission shaft 2. The operating table 3 serves as a platform for placing precision metal parts to be welded. It is firmly connected to the top of the transmission shaft 2, which can ensure that a stable support surface is provided for the metal parts during the operation of the equipment, thereby ensuring the smooth progress of the welding operation. A fixed block 4 is fixedly connected to the bottom of the operating table 3. The fixed block 4 plays the role of connecting and fixing other components. It provides a reliable installation position for components such as the pneumatic cylinder 5, ensuring the relative position stability between the components.

[0033] The inner wall of the fixed block 4 is fixedly connected to a pneumatic cylinder 5. When the device is started, the contraction of the pneumatic cylinder 5 drives the transmission block 6 to move the pneumatic cylinder 5 smoothly. By converting the air pressure energy into mechanical motion, the transmission block 6 can move in a predetermined direction and speed. This pneumatic drive method can accurately control the movement of the transmission block 6, thereby providing accurate power transmission for subsequent clamping actions, ensuring the continuity and accuracy of the entire clamping process. The driving end of the pneumatic cylinder 5 is fixedly connected to the transmission block 6. As a key component of power transmission, the transmission block 6 effectively transmits the power of the pneumatic cylinder 5 to the follower plate 7 and other components, so that each component can work together to achieve accurate clamping operation of the metal part. The bottom two sides of the transmission block 6 are movably connected to the follower plate 7. The follower plate 7 can flexibly rotate according to the movement of the transmission block 6, thereby driving the driven plate 8 to perform corresponding actions. It is an important link in the transmission chain for achieving the clamping action.

[0034] The top of the follower plate 7 is movably connected to a follower plate 8. Driven by the follower plate 7, the follower plate 8 slides along the track 9. Its precise motion trajectory and speed control play an important role in the consistency and accuracy of the entire clamping action, ensuring that the subsequent components can work together in the expected order and manner. The top of the follower plate 8 is slidably connected to the track 9. The track 9 provides a precise guide for the sliding of the follower plate 8, allowing the follower plate 8 to move along a predetermined route, thereby ensuring that the clamp 10 can accurately clamp the metal part. The top of the follower plate 8 is fixedly connected to the clamp 10. The movement of the two clamps 10 clamps the material. By precisely controlling the movement of the clamps 10, the precision metal parts to be welded can be firmly clamped, preventing the metal parts from shifting during the welding process, thereby improving the accuracy and quality of the welding. The inner wall of the box 1 is equipped with a rotating assembly for moving the equipment. The rotating assembly can adjust the angle of the operating table 3 so that the welding position can be more accurately aligned with the laser beam, improving the welding effect.

[0035] The rotating assembly has a protective shell 26, which protects the internal rotating assembly components, prevents them from being damaged by external factors, and ensures that the rotating assembly can operate stably and reliably. The front end of the protective shell 26 is fixedly connected to a moving assembly for the movement of the equipment. The moving assembly can realize the movement of the entire equipment within a certain range, making it convenient to accurately move the material to the appropriate welding position, thereby improving the convenience and accuracy of the welding operation. A connecting assembly for disassembly of the equipment is installed on the top of the box 1. The connecting assembly facilitates the disassembly and replacement of related parts of the equipment. When the laser is damaged or needs to be replaced, the operation can be easily completed through the connecting assembly, thereby improving the maintainability of the equipment.

[0036] The moving assembly includes a motor 2 13, the driving end of which is fixedly connected to a follower plate 2 14. The motor 2 13 serves as the power source of the moving assembly, providing power to the follower plate 2 14 so that it can push subsequent components to move. The other end of the follower plate 2 14 is externally slidably connected to a hole plate 15. The follower plate 2 14 effectively transmits the power of the motor 2 13 to the hole plate 15 through the sliding connection with the hole plate 15, thereby pushing the hole plate 15. The other end of the hole plate 15 is fixedly connected to the outer wall of the motor 12. When the motor 2 13 is started to drive the follower plate 2 14 to push the hole plate 15, the protective shell 26 fixed at the other end of the hole plate 15 slides, thereby realizing the movement of the entire equipment within a certain range, facilitating the accurate movement of the material to the appropriate welding position, improving the convenience and accuracy of the welding operation, reducing the workload of manually adjusting the position of the material, and improving the efficiency of the welding work.

[0037] The moving assembly includes a motor 2 13, the driving end of which is fixedly connected to a follower plate 2 14. The motor 2 13 serves as the power source of the moving assembly, providing power to the follower plate 2 14 so that it can push subsequent components to move. The other end of the follower plate 2 14 is externally slidably connected to a hole plate 15. The follower plate 2 14 effectively transmits the power of the motor 2 13 to the hole plate 15 through the sliding connection with the hole plate 15, thereby pushing the hole plate 15. The other end of the hole plate 15 is fixedly connected to the outer wall of the motor 12. When the motor 2 13 is started to drive the follower plate 2 14 to push the hole plate 15, the protective shell 26 fixed at the other end of the hole plate 15 slides, thereby realizing the movement of the entire equipment within a certain range, facilitating the accurate movement of the material to the appropriate welding position, improving the convenience and accuracy of the welding operation, reducing the workload of manually adjusting the position of the material, and improving the efficiency of the welding work.

[0038] Reference Figure 4 , Figure 5 The connection assembly includes a cylindrical handle 19. The cylindrical handle 19 is an important structure for connecting components such as the laser head 25. It provides a stable connection foundation for each component, ensuring that the laser head 25 can maintain an accurate position relationship during operation. The outer wall of the cylindrical handle 19 is fixedly connected with multiple positioning blocks 20. The positioning blocks 20 can further position and reinforce the cylindrical handle 19, ensuring the stability of the connection between the cylindrical handle 19 and other components. Two of the positioning blocks 20 are slidably connected to the inner walls of the snap hooks 21. The snap hooks 21 achieve the locking and releasing functions of the positioning column 24 by sliding on the inner walls of the positioning blocks 20. When the laser head 25 needs to be replaced, the snap hooks 21 can be easily operated to release the lock on the positioning column 24.

[0039] The bottom of the buckle 21 is fixedly connected to a spring 22, which provides elastic restoring force for the buckle 21, so that the buckle 21 can maintain a locked state on the positioning column 24 when no external force is applied, ensuring that the laser head 25 is firmly connected during normal operation. The bottom of the buckle 21 is fixedly connected to a telescopic column 23, which can expand and contract accordingly with the movement of the buckle 21, playing a role of auxiliary support and transmission, ensuring that the movement of the buckle 21 can be accurately transmitted to the positioning column 24. The other end of the telescopic column 23 away from the buckle 21 is coupled to the positioning column 24, and the positioning column 24 is raised and lowered under the drive of the telescopic column 23. When the tail ends of the two buckles 21 are lifted, the positioning column 24 rises to release the laser head 25 for replacement, thereby improving the maintainability of the equipment, facilitating the replacement operation of the laser head 25, reducing equipment maintenance time, and improving the overall work efficiency of the equipment.

[0040] The bottom end of the positioning post 24 is coupled to a laser head 25. As a key component of laser welding, the laser head 25 can be accurately fixed to the inner wall of the cylindrical handle 19 through the coupling connection of the positioning post 24, ensuring that the laser head 25 can accurately emit the laser beam during the welding process and accurately weld the metal parts. The outer wall of the laser head 25 is slidably connected to the inner wall of the cylindrical handle 19. This sliding connection method allows the laser head 25 to be adjusted to a certain extent on the inner wall of the cylindrical handle 19. When the laser head 25 needs to be replaced, it can be more conveniently removed from the inner wall of the cylindrical handle 19, improving the maintainability of the equipment and reducing the difficulty of replacing the laser head 25, thereby shortening the equipment maintenance time and improving the overall work efficiency of the equipment.

[0041] Reference Figure 1 , Figure 3 and Figure 4 , a slide 17 is provided on the top of the box 1. The slide 17 provides a precise guide for the sliding of the base 18, so that the base 18 can slide on the top of the box 1 according to a predetermined route, ensuring that the relative position relationship between the various components of the equipment is accurate. The top of the box 1 is slidably connected to the base 18. The base 18 serves as a structure for supporting and connecting other components. Its sliding on the slide 17 can flexibly adjust the layout of the equipment, facilitate the installation and maintenance of subsequent components, and also provide a certain degree of flexibility for the overall movement of the equipment. The bottom of the base 18 is slidably connected to the outside of the slide 17. Through this sliding connection method, the tightness of the connection between the base 18 and the box 1 and the smoothness of the sliding are guaranteed, so that the various components of the equipment can work together during operation without jamming or disconnection.

[0042] Support columns 11 are fixedly connected to the bottom of the four ends of the operating table 3. These columns provide a stable support for the operating table 3, ensuring that it remains level and stable when placing metal parts and during equipment operation, preventing any shaking of the operating table 3 from affecting the accuracy and quality of the welding operation. The top of the track 9 is fixedly connected to the bottom of the operating table 3. This fixed connection makes the track 9 and the operating table 3 form an integral unit, ensuring that the position of the driven plate 8 relative to the operating table 3 is relatively stable when sliding on the track 9, thereby ensuring that the clamping plate 10 can accurately clamp the metal parts.

[0043] The outside of the motor 2 13 is fixedly connected to a base plate 16, which provides a stable installation base for the motor 2 13, ensuring that the motor 2 13 will not shake or shift during operation, thereby ensuring that it can continuously and stably provide power to the follower plate 2 14. The two ends of the protective shell 26 are slidably connected to the inner wall of the base plate 16. This sliding connection method allows the protective shell 26 to slide smoothly on the inner wall of the base plate 16, providing a flexible adjustment method for the overall movement of the equipment, and facilitating the accurate movement of materials to the appropriate welding position. The base plate 16 is fixedly connected to the inner wall of the box body 1. By fixing the base plate 16 to the inner wall of the box body 1, the connection stability between the internal components of the equipment is further strengthened, ensuring that the entire device can operate stably and reliably, and improving the service life of the equipment.

[0044] Working principle: When the equipment is started, the contraction of the pneumatic cylinder 5 drives the transmission block 6 to move the pneumatic cylinder 5 smoothly. By converting the air pressure energy into mechanical motion, the transmission block 6 can move in a predetermined direction and speed. The movement of the transmission block 6 drives the driven plate 8 to slide on the track 9. The movement of the driven plate 8 drives the movement of the top clamping plate 10. Its precise motion trajectory and speed control play an important role in the consistency and accuracy of the entire clamping action, ensuring that the subsequent components can work together in the expected order and manner. The movement of the two clamping plates 10 clamps the material. When the material is not in the required position, By precisely controlling the speed and direction of rotation of motor 12, the operating table 3 can be accurately adjusted to a suitable angle, which is convenient for subsequent welding operations and enables the welding position to be more accurately aligned with the laser beam, thereby improving the welding effect. The motor 2 13 is started to drive the follower plate 2 14 to push the orifice plate 15, and the protective shell 26 fixed at the other end of the orifice plate 15 slides. After the two motors are started to facilitate the material to move to the correct position, the laser is turned on. When the laser is damaged or needs to be replaced, the tail ends of the two buckles 21 are lifted to raise the positioning column 24 to loosen the laser head 25 for replacement, thereby improving the maintainability of the equipment.
