[0026] As a technical optimization of this utility model, a laser cutting head 4 is installed on the lifting seat 3, and an oil cylinder for controlling the lifting and moving of the laser cutting head 4 is provided inside the lifting seat 3.
[0027] For the above example, those skilled in the art should know that when implementing the above technical solution, the mounting base 2 can be equipped with an existing control base for controlling the rotation of the lifting seat 3, thereby controlling the rotation of the corresponding laser cutting head 4, so as to realize the cutting operation of the bevel end face and the setting of the bevel end face angle.
[0028] As a technical optimization of this utility model, the rotation control mechanism includes a rotating disk 7, the axis of which is rotatably connected to a side bracket 5. An electric telescopic rod 6 is horizontally mounted on one side of the rotating disk 7, and a gear disk 8 is coaxially fixed on the other side of the rotating disk 7. A motor 9 is fixed on the side bracket 5, and a gear 17 is coaxially fixed to the motor 9. The gear 17 meshes with the gear disk 8. The motor 9 can precisely control the rotation of the gear 17, which drives the gear disk 8 to rotate, and the gear disk 8 drives the electric telescopic rod 6 to rotate.
[0029] As a technical optimization of this utility model, the grinding mechanism includes an angle grinder 10, a polishing disc 11 matched with the angle grinder 10, and an installation mechanism matched with the angle grinder 10.
[0030] For the above examples, those skilled in the art should know that when implementing the above technical solutions, the angle grinder 10 can be an existing handheld device, and the angle grinder 10 can be disassembled and used by hand.
[0031] As a technical optimization of this utility model, the installation mechanism includes a mounting frame 12, the bottom of which is detachably and fixedly connected to the angle grinder 10. A sliding block 13 is slidably provided inside the mounting frame 12, and a spring 14 is fixed between the sliding block 13 and the mounting frame 12. The sliding block 13 is fixedly connected to the telescopic end of the electric telescopic rod 6. The electric telescopic rod 6 can control the movement of the angle grinder 10 and the corresponding polishing disc 11.
[0032] As a technical optimization of this utility model, a positioning machine 15 is also installed on the substrate 1. The positioning machine 15 is used to position and move the pipe body 16, and the pipe body 16 can be moved to the bottom of the laser cutting head 4.
[0033] For the above example, those skilled in the art should know that when implementing the above technical solution, the positioning machine 15 is used to clamp and position the pipe body 16, and the positioning machine 15 can be matched with the existing feeding mechanism, which is used to transport the pipe body 16.
[0034] As a technical optimization of this utility model, the bottom of the laser cutting head 4 is directly opposite the axis of the pipe body 16, the electric telescopic rod 6 is inclined toward the pipe body 16, and the polishing surface of the polishing disc 11 faces the edge of the pipe body 16. The polishing disc 11 is used to abut against the pipe body 16 and polish it. When abutting, the corresponding spring 14 can play a buffering role, while the sliding block 13 plays a stabilizing role.
[0035] In this invention, the working principle of the device is as follows:
[0036] After the laser cutting head 4 performs bevel cutting on the pipe body 16, it can control the pipe body 16 to move forward and control the angle grinder 10 to move via the electric telescopic rod 6. This allows the polishing disc 11 of the angle grinder 10 to come into contact with the bevel edge of the pipe body 16. The angle grinder 10 then starts, driving the polishing disc 11 to rotate, thus polishing the bevel edge of the pipe body 16. After polishing, the pipe body 16 can be reset, and the laser cutting head 4 can continue subsequent cutting operations, such as slot cutting, and finally, bevel end face cutting again. Automatic bevel polishing effectively improves product quality, facilitates subsequent welding and butt welding of the pipe body 16, and enhances polishing efficiency. Furthermore, it effectively integrates with other equipment, namely the positioning machine 15, allowing polishing to be performed immediately after bevel cutting, thus significantly improving work efficiency.
[0037] In the above operation, the polishing disc 11 can be adjusted to the corresponding angle according to the bevel angle of the pipe body 16. This is achieved by starting the motor 9, which precisely controls the rotation of the gear 17. The gear 17 drives the gear disk 8 to rotate, which in turn drives the electric telescopic rod 6 to rotate. This ultimately adjusts the angle between the angle grinder 10 and the corresponding polishing disc 11, ensuring that the polished surface of the polishing disc 11 is parallel and in contact with the bevel angle of the pipe body 16 during subsequent grinding operations. Simultaneously, when the polishing disc 11 abuts against the pipe body 16, the corresponding spring 14 provides a cushioning effect, while the sliding block 13 maintains stability.
[0038] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
