[0002] Cutting machines are frequently used in today's industry. There's actually not just one type of cutting machine, but many different types, depending on their function or principle. Common ones include flame cutting machines, plasma cutting machines, laser cutting machines, and water jet cutting machines. However, laser cutting machines are the most efficient of these cutting machines, and their cutting precision is unmatched by other cutting machines. Laser cutting machines are also categorized into small 3D laser tube cutting machines, ultra-small tube high-speed 3D laser tube cutting machines, and other laser tube cutting machines.

[0003] Laser tube cutting machines in the prior art generally include horizontal or side-mounted three-chuck laser tube cutting machines.

[0026] As an optional technical solution of the present invention, it also includes a control system for controlling the pushing power member, the telescopic power member and the laser cutting machine.

[0027] By adopting the above technical solution: the pipe can be automatically advanced and cut through the control system.

[0028] The working principle and beneficial effects of the present invention are:

[0029] 1. The frame is used to fix and support the installation of this equipment. The laser cutting mechanism installed on it is used to generate a laser beam to cut the pipe. When cutting the pipe, the clamping and pushing mechanism cooperates with the linkage mechanism to clamp the end of the pipe and push the pipe toward the laser cutting mechanism. At this time, the laser cutting mechanism first descends a certain displacement, and the synchronous mechanism drives the middle clamping and cleaning mechanism to clean the surface of the pipe. When the part to be cut of the pipe is at the lower part of the laser cutting mechanism, the laser cutting mechanism continues to descend, and the middle clamping and cleaning mechanism is used to fix both sides of the part to be cut of the pipe, so as to improve the cutting accuracy.

[0030] 2. The telescopic power part can drive the laser cutting machine to move up and down. The positioning sliding component can make the laser cutting machine move up and down more accurately.

[0031] 3. The clamping cleaning component can clean the surface of the pipe fitting and fix the two sides of the pipe fitting to be cut together with the clamping component.

[0032] 4. When the elastic telescopic rod descends, it drives the upper arc-shaped holding piece to descend, and at the same time drives the lower arc-shaped holding piece to move upward through the cooperative mechanism, so that the upper arc-shaped holding piece and the lower arc-shaped holding piece gradually approach each other, thereby gradually clamping the pipe fitting.

[0033] 5. As the upper arc-shaped holding piece gradually moves downward, it first drops a certain amount so that the pipe fitting is not locked. At this time, the first half-arc brush body gradually approaches the second half-arc brush body, and the outer surface of the pipe fitting is cleaned while the pipe fitting is being pushed.

[0034] 6. The end of the pipe is pushed by the pushing power piece. The chuck assembly is in an open state at this time. The end of the pipe is in the chuck assembly. Under the action of the linkage structure, the chuck assembly gradually contracts and clamps the end of the pipe. Specifically, driven by the pushing power piece, the main groove column gradually approaches the touch part.

In order to facilitate the installation of the laser cutting mechanism 300, a vertical plate 210 is provided on the upper middle side of the mounting side plate 200, and a horizontal plate 220 is provided on the top of the vertical plate 210. The laser cutting mechanism 300 slidingly arranged on the vertical plate 210 is installed on the horizontal plate 220, and the laser cutting mechanism 300 is connected to the middle clamping and cleaning mechanism 500 through a synchronization mechanism 400. A clamping and pushing mechanism 600 is provided on one side of the mounting side plate 200, and a linkage mechanism 700 for driving the clamping and pushing mechanism 600 is also provided on the mounting side plate 200. An arc-shaped hosting member 800 is also provided on the upper surface of the frame body 100.

[0046] The basic principle of this embodiment is as follows: the frame body 100 is used to fix and support the installation of this equipment, and the laser cutting mechanism 300 installed thereon is used to generate a laser beam to cut the pipe. When cutting the pipe, the end of the pipe is clamped and pushed toward the laser cutting mechanism 300 through the cooperation of the clamping and pushing mechanism 600 and the linkage mechanism 700. At this time, the laser cutting mechanism 300 first descends a certain displacement, and drives the middle clamping and cleaning mechanism 500 to clean the surface of the pipe through the synchronization mechanism 400. When the part to be cut of the pipe is at the lower part of the laser cutting mechanism 300, the laser cutting mechanism 300 continues to descend, and the two sides of the part to be cut of the pipe are fixed through the middle clamping and cleaning mechanism 500, so as to improve the cutting accuracy.

[0048] The positioning sliding assembly includes two slide grooves arranged on the shell of the laser cutting machine 320 and two slide rails 330 arranged on the vertical plate 210. The slide grooves are slidably arranged on the slide rails 330. Through the cooperation between the slide rails 330 and the slide grooves, the laser cutting machine 320 can move up and down more accurately, forming a positioning effect for the laser cutting machine 320.

[0049] Reference Figure 2 The synchronization mechanism 400 in this embodiment includes a connecting plate 410 arranged on both sides of the laser cutting machine 320. The lower part of the connecting plate 410 is provided with an elastic telescopic rod 420. The lower part of the elastic telescopic rod 420 is connected to the middle clamping and cleaning mechanism 500. When the laser cutting machine 320 descends, the elastic telescopic rod 420 is driven to descend through the connecting plate 410.

One side of the trigger rod 930 is located at the lower part of the L-shaped rod 910, and the other side of the trigger rod 930 is connected to the lower arc-shaped holding piece 530.

[0054] When the upper arc-shaped holding piece 510 moves downward, the lower end of the L-shaped rod 910 contacts the trigger rod 930, pushing the trigger rod 930 to move downward. Due to the lever effect, the other end of the trigger rod 930 drives the lower arc-shaped holding piece 530 to move upward, gradually approaching the upper arc-shaped holding piece 510.

Under the action of the linkage structure, the chuck assembly gradually contracts and clamps the end of the pipe. The pushing power member 620 can be an electric cylinder or a pneumatic cylinder.
