[0024] The internal support mechanism also includes a plurality of convex grooves 15 opened on the outer wall of the fixed frame 10, the inner wall of the convex groove 15 is slidably connected with a convex slider 16, the outer wall of the convex slider 16 is fixedly connected with an internal support rod 17, and the plurality of internal support rods 17 are evenly distributed on the outer wall of the fixed frame 10 in a circular array with the movable cylinder 12 as the axis. The internal support rod 17 is hinged to the outer wall of the movable cylinder 12 with two connecting rods 18, and the end of the connecting rod 18 away from the internal support rod 17 is hinged to the outer wall of the movable cylinder 12.

[0025] The end of the rotating shaft 9 away from the fixed frame 10 passes through the movable seat 2 and is fixedly connected to the driven wheel 19. The outer wall of the movable seat 2 located below the driven wheel 19 is rotatably connected to the driving wheel 20. The driving wheel 20 and the outer wall of the driven wheel 19 are jointly installed with a belt 21.

[0026] A driving motor 22 is fixedly mounted on an outer wall of the movable seat 2 away from the fixed frame 10 via a motor bracket, and a terminal end of an output shaft of the driving motor 22 is fixedly connected to a middle outer wall of the driving wheel 20 .

[0027] The top outer wall of the base 1 is fixedly connected to two guide rails 4 , and the bottom outer wall of the movable base 2 is fixedly connected to two guide blocks 5 , which are slidably connected to the outer walls of the guide rails 4 .

[0028] The top outer wall of the base 1 located between the two guide rails 4 is rotatably connected to a screw rod 6, the bottom middle outer wall of the movable base 2 is fixedly connected to a nut seat 7, the nut seat 7 is threadedly connected to the outer wall of the screw rod 6, and one end of the screw rod 6 is fixedly connected to a handle 8.

[0029] A plurality of fixing feet 3 are fixedly connected to the outer walls on both sides of the base 1 , and the plurality of fixing feet 3 are evenly distributed on the outer walls on both sides of the base 1 .

[0030] The implementation principle of a round tube cutting table in the embodiment of the present application is as follows: when in use, the base 1 is fixed to the cutting machine bed by screws through multiple fixing feet 3, and then one end of the round tube is sleeved on the outer wall of multiple inner support rods 17, and then the servo motor 14 is started through the inner support mechanism, and the output end of the servo motor 14 drives the threaded rod 13 to rotate on the inner surface of the threaded cylinder 11. Since the threaded cylinder 11 is threadedly connected with the threaded rod 13, the threaded rod 13 is telescopically moved on the inner wall of the threaded cylinder 11. When the threaded rod 13 is retracted into the inside of the threaded cylinder 11, it drives the movable cylinder 12 to slide on the outer wall of the threaded cylinder 11 toward the fixed frame 10. At this time, the movable cylinder 12 will push the multiple inner support rods 17 to expand synchronously through the multiple connecting rods 18. When the inner support rods 17 are expanded, the inner wall of the round tube is supported and fixed. When the threaded rods 13 extend out of the threaded tube 11, the movable tube 12 is driven to slide on the outer wall of the threaded tube 11 away from the fixing frame 10. At this time, the movable tube 12 pulls the inner support rods 17 to shrink synchronously through the multiple connecting rods 18, thereby releasing the fixation of the round tube. Through the expansion or contraction of the multiple inner support rods 17, it can adapt to the fixation of round tubes with different inner diameters. It is worth noting that when the inner support rods 17 move, they drive the convex slider 16 to slide on the inner wall of the convex slide groove 15, which plays a limiting role, so that the inner support rods 17 can always move linearly, increasing the movement stability.

[0031] When it is necessary to adjust the rotating round tube according to the cutting position, start the driving motor 22, and the output shaft of the driving motor 22 drives the driving wheel 20 to rotate, and the driving wheel 20 drives the driven wheel 19 to rotate through the belt 21, and then the driven wheel 19 drives the rotating shaft 9 to rotate, and the round tube fixed on the fixed frame 10 is driven by the rotating shaft 9 to rotate and adjust. When it is necessary to adjust the cutting length of the round tube, the handle 8 can be turned, and the handle 8 drives the screw rod 6 to rotate on the inner surface thread of the nut seat 7, so as to drive the nut seat 7 to move along the outer wall of the screw rod 6, and then the nut seat 7 drives the moving seat 2 to move. At this time, the round tube fixed on the moving seat 2 moves left and right, and the cutting length can be adjusted. When the moving seat 2 moves, it will drive the two guide blocks 5 to slide on the outer wall of the guide rail 4, which plays a limiting role, so that the moving seat 2 always moves linearly and stably, thereby increasing the movement stability.
