[0003] In the process of implementing the embodiments of the present disclosure, it is found that at least the following problems exist in the related art:
[0004] When the conventional clamping device is used for laser welding, the position adjustment of the clamp assembly is not accurate enough, resulting in deviation of the welding position and affecting the welding quality. In addition, the clamping and loosening actions of the clamp assembly are usually performed separately, and when welding multiple pipes of the same size, the pipes need to be clamped one by one, which prolongs the preparation time before welding and reduces the work efficiency.

[0007] Between the first sliding block plate and the second sliding block plate, the device further comprises a first threaded rod and a second threaded rod, the thread directions of the two threaded rods are opposite to ensure that they move synchronously and reversely when driven. The first threaded rod and the second threaded rod are both driven and controlled accurately by a driving motor, thereby ensuring accurate alignment during the welding process.
[0008] In order to achieve accurate clamping of the welded pipe, a first clamp assembly is screwed onto the first threaded rod, and a second clamp assembly is screwed onto the second threaded rod. The two clamp assemblies are designed to effectively clamp the pipe before welding, ensuring stability and accuracy during the welding process.
[0009] In order to further improve the work efficiency, the number of the first clamp assembly and the second clamp assembly is set to 4, and they are configured in pairs.

To ensure stable operation of the drive motors, the two drive motors are mounted on a solid motor fixing frame. The motor fixing frame is closely connected to the bearing plate, which not only ensures the stability of the motor, but also facilitates maintenance and replacement.
[0012] In addition, in order to further protect the drive motors and threaded rods from damage, a coupling is provided at the connection between each of the two drive motors and the first and second threaded rods. The coupling is designed to consider the need for buffering and shock absorption, and can effectively absorb and disperse impact forces generated during operation, thereby prolonging the service life of the entire system.
[0013] Finally, the first and second clamp assemblies are designed very cleverly, and they are both composed of a clamp seat and a clamp plate.

[0024] The technical scheme in the embodiments of the utility model will be described clearly and completely in combination with the drawings in the embodiments of the utility model, obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor are within the protection scope of the utility model.
[0025] Please refer to Figs. 1-2 The utility model provides a kind of technical scheme: a clamping device for laser welding machine, its main features are that it includes a bearing plate 1, the surface of the bearing plate 1 is designed with first sliding plate 2 and second sliding plate 3, the two sliding plates are respectively located at the two sides of the long side of bearing plate 1, to provide stable support for welding operation.
[0026] Between the first slider plate 2 and the second slider plate 3, the device further comprises a first threaded rod 4 and a second threaded rod 5, the screw directions of which are opposite to ensure that they can move synchronously and reversely when driven. The first threaded rod 4 and the second threaded rod 5 are both driven by a driving motor 6 to realize precise driving control, thereby ensuring the precise alignment during the welding process.
[0027] In order to realize the precise clamping of the welded pipe, the first threaded rod 4 is screwed with a first clamp assembly 7, and the second threaded rod 5 is screwed with a second clamp assembly 8. The two clamp assemblies 7 and 8 are designed to effectively clamp the pipe before welding, ensuring stability and accuracy during the welding process.
[0028] In order to further improve work efficiency, the number of the first clamp assembly 7 and the second clamp assembly 8 is set to 4, and they are arranged in pairs. Such design enables the operator to quickly clamp multiple same-size pipes to be welded at the same time, significantly improving the efficiency and productivity of the welding operation.
[0029] More specifically, the plate wall of the first slider plate 2 and the second slider plate 3 is provided with 2 oil-free bushings, which are carefully designed and installed inside the slider plate to ensure that the first threaded rod 4 and the second threaded rod 5 can be smoothly inserted into the corresponding oil-free bushings. The purpose of this design is to reduce the friction during sliding, thereby improving the service life of the entire device and ensuring its high efficiency and stability during long-term operation.
[0030] Further, the number of driving motors 6 is set to 2, and the two driving motors 6 independently drive the first threaded rod 4 and the second threaded rod 5, respectively. In order to ensure the stable operation of the driving motor 6, the two driving motors 6 are both installed on a solid motor fixing frame 10. The motor fixing frame 10 is closely connected with the bearing plate 1, and this structure design not only ensures the stability of the motor, but also facilitates maintenance and replacement.
[0031] In addition, in order to further protect the driving motor 6 and the threaded rod 45 from damage, the connection between the two driving motors 6 and the first threaded rod 4 and the second threaded rod 5 is provided with a shaft coupling 9. The shaft coupling 9 takes into account the needs of buffering and shock absorption, and can effectively absorb and disperse the impact force generated during operation, thereby prolonging the service life of the entire system.
[0032] Finally, the first clamp assembly 7 and the second clamp assembly 8 are both designed very ingeniously, and they are both composed of a clamp base and a clamp plate. The clamp base is screwed onto the corresponding threaded rod 4 or 5, which ensures the accurate position and stable clamping of the clamp assembly. The clamp plate and the clamp base are connected by bolts, which is simple and reliable. In addition, the clamping surface of the clamp plate is specially designed with a V-shaped clamping groove, which can better fix the pipe to be welded and ensure its stability during welding, thereby significantly improving the welding quality.
[0033] Working principle: When the device is working, the two drive motors 6 start working. The two drive motors 6 drive the first threaded rod 4 and the second threaded rod 5 to rotate respectively. Since the threaded directions of the first threaded rod 4 and the second threaded rod 5 are opposite, when they are driven to rotate by the drive motor 6, the first clamp assembly 7 and the second clamp assembly 8 on the first threaded rod 4 and the second threaded rod 5 will move in opposite directions.
[0034] The number of the first clamp assembly 7 and the second clamp assembly 8 is 4, and they are respectively arranged in pairs on the first threaded rod 4 and the second threaded rod 5. These clamp assemblies are connected with the threaded rods by screwing, so when the threaded rods rotate, the clamp assemblies will move along the threaded rods. Since the oil-free bushings are arranged in the plate walls of the first sliding block plate 2 and the second sliding block plate 3, the first threaded rod 4 and the second threaded rod 5 can move smoothly in the oil-free bushings, reducing friction and wear.
[0035] Each clamp assembly is composed of a clamp base and a clamp plate. The clamp base is screwed onto the corresponding threaded rod, and the clamp plate is connected with the clamp base by bolts. The clamping surface of the clamp plate is provided with a V-shaped clamping groove, which makes the clamp assembly firmly clamp the pipe to be welded.
[0036] When the operator needs to clamp the pipe to be welded, they only need to put the pipe into the corresponding clamp assembly, and then start the drive motor 6 to make the clamp assembly move to the appropriate position along the threaded rod and clamp the pipe. Since the number of the first clamp assembly 7 and the second clamp assembly 8 is 4, and they are respectively arranged in pairs, the operator can quickly clamp multiple pipes to be welded of the same size, improving the work efficiency.
[0037] Once the pipe is clamped, the laser welding machine can start the welding work. After welding, the operator can start the reverse function of the drive motor 6 to make the clamp assembly move to the initial position along the threaded rod, and then take out the welded pipe.
