[0003] A pipe cutting machine is a pipe processing equipment. Generally, the pipe is fed through a feeding device and clamped by a chuck. Finally, a cutting head is used to cut the entire pipe into multiple fixed-length or different-length sections. However, the current pipe cutting machine has a relatively simple structure. During actual processing, it is difficult to accurately and quickly adjust the spacing between the main and auxiliary chucks according to the requirements of product processing. The working efficiency is low and the cutting accuracy is also low. Therefore, there is a need for improvement. Summary of the invention

[0004] The present invention provides a laser cutting device which is similar to a sub-chuck and has high cutting accuracy. It can ensure the coaxiality of all parts during processing and ensure the processing quality of products. The distance between the main and sub-chucks and the laser device can be adjusted according to needs. The main and sub-chucks can be ensured to work coaxially and at the same speed. It is easy to operate and control, reduce manual operation, and increase work efficiency. It solves the technical problems in the prior art that the current pipe cutting machine relies on manual operation, ordinary pipe cutting machines are difficult to ensure the level of shaft pipe products during processing, which easily affects the processing quality of products, and the main and sub-chucks of the pipe cutting machine are not convenient to adjust the position or distance according to needs, and are not convenient to cooperate with the cutting equipment.

The laser cutting assembly can be used to laser process or cut shaft tube products. The main chuck and the auxiliary chuck are synchronously driven through a linkage mechanism. When the main chuck rotates, the auxiliary chuck will also rotate synchronously. The synchronous rotation is achieved through a mechanical structure without the need for an additional motor or system for control. The auxiliary chuck and the laser cutting assembly are both installed on the processing table. The horizontal lateral movement of the processing table can be controlled and adjusted by the drive assembly.

[0025] The technical solution of the invention is further specifically described below through embodiments and in conjunction with the accompanying drawings.

[0026] Example:

[0027] like Figure 1and 2 And as shown in 3 and 4 and 5 and 6 and 7 and 8 and 9,

[0028] A pipe cutting machine comprises a machine tool 1, a main chuck 2 is rotatably mounted on the left side of the machine tool 1, a processing table 3 which can be horizontally moved is mounted on the right side of the machine tool 1, a sub-chuck 4 is rotatably mounted on the processing table 3, the sub-chuck 4 is coaxially corresponding to the main chuck 2, the main chuck 2 and the sub-chuck 4 are synchronously driven through a linkage mechanism, and a laser cutting component which cooperates with the sub-chuck 4 to cut the pipe is also mounted on the processing table 3.

[0030] The linkage mechanism includes a main gear 5 fixed to the end of the main chuck 2, a drive motor 6 is fixedly installed on the machine tool 1 on the front side of the main chuck 2, a main transmission gear 8 meshing with the main gear 5 is installed on the right end of the drive motor 6, and the drive motor 6 and the auxiliary chuck 4 are driven by a linkage member.

[0031] The linkage parts include a secondary transmission gear 9 fixed to the right side of the main transmission gear. A linkage rod 10 is rotatably mounted on the machine tool 1 on the right side of the drive motor 6. The linkage rod 10 runs through the machine tool 1, and a plurality of spline grooves 18 are provided on the outer surface of the linkage rod 10. A linkage main gear 11 meshing with the secondary transmission gear 9 is fixedly mounted on the left end of the linkage rod 10.

[0032] The right end of the linkage rod 10 is sleeved with a linkage sub-gear 12, which is engaged with the spline groove 18 on the surface of the linkage rod 10, and can slide along the linkage rod. The linkage sub-gear 12 is connected to the auxiliary chuck 4 through a belt 13. The outer wall of the auxiliary chuck 4 is provided with a mounting groove 14, and the belt 13 is embedded in the mounting groove 14.

[0033] A tensioning wheel 15 is installed between the linkage sub-gear 12 and the auxiliary chuck 4. The belt 13 is sleeved outside the linkage sub-gear 12 and the auxiliary chuck 4, and the belt 13 passes around the tensioning wheel 15.
