DETAILED DESCRIPTION

[0024] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0025] A follow-up fixture for a laser tube cutting machine, such as Figures 1 to 5 As shown, it includes a base 1, and a mounting frame 2 is slidably provided on the base 1. Specifically, a slide rail 17 is provided on the mounting frame 2, and the slide rail 17 is arranged in a vertical direction. A slider 18 is slidably connected to the slide rail 17, and the slider 18 is connected to the base 1 and guided by the cooperation of the slide rail 17 and the slider 18.

[0026] Furthermore, a driving component 15 is provided on the base 1. The driving component 15 is preferably a cylinder. As another solution, an oil cylinder can also be used. The output end of the driving component 15 is connected to the mounting frame 2. The driving component 15 is used to drive the mounting frame 2 to move, so that the mounting frame 2 rises or falls.

[0027] The mounting frame 2 is provided with a support seat 3, and the support seat 3 is slidably connected to the mounting seat 4. Specifically, the support seat 3 is provided with a second slide rail 19, which is arranged in a vertical direction, and a second slider 20 is slidably connected to the second slide rail 19. The second slider 20 is connected to the mounting seat 4 and is guided by the cooperation of the second slide rail 19 and the second slider 20.

[0028] A support member 6 is provided on the mounting frame 2, and the support member 6 is used to support the pipe. The support member 6 is cylindrical, and the outer wall of the pipe abuts against the outer wall of the support member 6, thereby supporting the pipe and ensuring the stability of the pipe during the cutting process.

[0029] It should be noted that in this embodiment, the cross-section of the pipe is rectangular. Therefore, as the pipe rotates, the position of the lowest point of the pipe changes. The driving component 15 drives the mounting frame 2 to move, so that the mounting frame 2 rises or falls, and the mounting frame 2 drives the support member 6, thereby changing the position of the support member 6, so that the pipe is close to or away from the support member 6, thereby adapting to the change in the lowest point position of the pipe during rotation, and ensuring that the support member 6 effectively supports the pipe.

[0030] The mounting seat 4 is rotatably connected to a clamping seat 5, which is used to clamp the pipe fitting, and the pipe fitting can drive the clamping seat 5. The clamping seat 5 is provided with a clamping opening 21 adapted to the pipe fitting. The pipe fitting passes through the clamping opening 21, that is, the pipe fitting is clamped by the clamping seat 5, thereby achieving stable positioning of the pipe fitting, thereby ensuring that the pipe fitting maintains concentricity during the cutting process, thereby ensuring the stability of the pipe fitting during the cutting process, and improving the accuracy of the pipe fitting during rotational cutting.

[0031] In this embodiment, there are at least two support seats 3 and the two are arranged opposite to each other, there are at least two mounting seats 4 and the two are arranged opposite to each other, and the clamping seat 5 is composed of two clamping blocks 51 arranged opposite to each other, and the two clamping blocks 51 are respectively connected to the two mounting seats 4. A positioning protrusion 22 is provided on each of the two clamping blocks 51, and a positioning groove 23 is provided on each of the two clamping blocks 51. The positioning protrusion 22 is adapted to the positioning groove 23. When the two clamping blocks 51 are spliced together, the positioning protrusion 22 of one of the clamping blocks 51 can be inserted into the positioning groove 23 of the other clamping block 51. The cooperation between the positioning protrusion 22 and the positioning groove 23 ensures the stability of the two clamping blocks 51 in the spliced state, thereby ensuring the stable clamping of the pipe fitting by the clamping seat 5.

[0032] A driving member 14 is installed on the mounting frame 2. The driving member 14 is preferably a double-rod cylinder. The output end of the driving member 14 is connected to the support seat 3. The driving member 14 is used to drive the two support seats 3 to move closer to or away from each other, thereby making the two support seats 3 drive the two mounting seats 4 to move closer to or away from each other, and the two mounting seats 4 drive the two clamping blocks 51 to move closer to or away from each other, thereby achieving clamping or loosening of the pipe fitting.

[0033] In this embodiment, two rollers 7 are rotatably provided on the two mounting seats 4, and a connecting member 13 is installed on the mounting seat 4. The connecting member 13 corresponds to the roller 7 one by one. The connecting member 13 adopts a connecting bolt, and the connecting bolt is threadedly connected to the mounting seat 4. A strip hole 12 is opened on the two mounting seats 4, and the connecting member 13 passes through the strip hole 12. The roller 7 is rotatably connected to the connecting member 13, and the roller 7 is located in the strip hole 12, so that the overall structure is more compact and the space occupancy can be effectively reduced.

[0034] An annular groove 8 is provided on the outer wall of the clamping seat 5. Specifically, an arc groove 81 is provided on the outer walls of the two clamping blocks 51. The two arc grooves 81 are spliced together to form an annular groove 8. The roller 7 extends into the annular groove 8, and the outer surface of the roller 7 is in contact with the inner wall of the annular groove 8, thereby realizing the rolling cooperation between the roller 7 and the clamping seat 5 and ensuring the relative stability of the roller 7 and the clamping seat 5.

[0035] Mounting plates 9 are provided on both sides of the two mounting seats 4, and positioning rods 10 are provided on the two mounting plates 9. Annular grooves 11 are provided on the end faces of both ends of the clamping seat 5. Specifically, semicircular grooves are provided on both sides of the two clamping blocks 51. The two semicircular grooves cooperate to form an annular groove 11. The positioning rod 10 is inserted into the annular groove 11, and the side wall of the positioning rod 10 is in contact with the side wall of the annular groove 11, so as to ensure the relative stability of the mounting seat 4 and the corresponding clamping block 51.

[0036] A limiting member 16 is provided on both support seats 3. The limiting member 16 is preferably a limiting bolt, which is threadedly connected to the support seat 3. The limiting member 16 is used to limit the mounting seat 4. Specifically, the bottom of the support seat 3 is abutted against the end of the limiting member 16 to limit the mounting seat 4, thereby achieving the limitation of the clamping seat 5.

[0037] The working principle of this utility model is as follows:

[0038] The two support seats 3 are driven away from each other by the driving member 14, so that the two support seats 3 respectively drive the two mounting seats 4 away from each other, and the two mounting seats 4 respectively drive the two clamping blocks 51 away from each other, then the pipe fitting is placed between the two clamping blocks 51, and then the two support seats 3 are driven towards each other by the driving member 14, so that the two support seats 3 respectively drive the two mounting seats 4 towards each other, and the two mounting seats 4 respectively drive the two clamping blocks 51 towards each other, and the two clamping blocks 51 cooperate to clamp the pipe fitting, and the outer wall of the pipe fitting abuts against the outer wall of the support member 6;

[0039] During the cutting process, the laser tube cutting machine drives the tube to rotate, and the tube will drive the clamping seat 5 to rotate. At the same time, the driving component 15 drives the mounting frame 2 to move, so that the mounting frame 2 rises or falls, and the mounting frame 2 drives the support 6 and the support seat 3 to rise or fall. The support seat 3 slides relative to the mounting seat 4. As the position of the support 6 changes, the tube approaches or moves away from the support 6, and the support 6 always supports the tube.

[0040] The specific embodiments described in this article are merely examples of the spirit of the present invention; technicians in the technical field of the present invention may make various modifications or additions to the described specific embodiments or replace them in a similar manner, but they will not deviate from the spirit of the present invention or exceed the scope defined by the attached claims.
