A telescopic mechanism 22 is arranged inside the movable frame 7, and the surface of the connecting column 25 passes through the movable frame 7 and is connected to the telescopic mechanism 22. The connecting column 25 can be extended and retracted through the telescopic mechanism 22, so as to realize the control of the outer tube 9. When the stainless steel pipe 2 is suspended for a long length, the end of the stainless steel pipe 2 can be expanded and clamped outward, so that the stainless steel pipe 2 will not vibrate or deform during processing, thereby improving the quality of laser cutting of the stainless steel pipe 2.

[0020] Four T-shaped slots 15 are evenly arranged on the surface of the cross fixing frame 14, and the T-shaped slots 15 are parallel to the support plate 12. A baffle 37 is fixedly arranged on the end of the support plate 12 close to the turntable 13, and a T-shaped slider 16 is fixedly installed on the end face of the baffle 37.

When the outer tube 9 moves toward the side of the movable frame 7 on the surface of the inner tube 17, the end of the connecting bar 11 close to the outer tube 9 will also move toward the side of the movable frame 7. At the same time, since the support plate 12 is slidably clamped in the T-shaped slot 15 through the T-shaped slider 16, the connecting bar 11 and the cross fixing frame 14 gradually tend to be parallel, thereby achieving the effect of supporting the support plate 12 outward, so that the support plate 12 can expand and clamp the inner wall of the stainless steel pipe fitting 2 outward.

[0021] A first gear assembly 31 is provided between the movable frame 7 and the turntable 13. The first gear assembly 31 includes a first driven gear 19 and a first driving gear 20.

The front end of the first driven gear 19 is fixedly connected to the turntable 13. A stepper motor 21 is provided inside the movable frame 7. The output end of the stepper motor 21 is connected to the first driving gear 20. Under the action of the first gear assembly 31, the stepper motor 21 can drive the turntable 13 to rotate. When the outward expansion positioning mechanism 8 clamps the stainless steel pipe fitting 2 outwardly, by rotating the turntable 13, the outward expansion positioning mechanism 8 and the stainless steel pipe fitting 2 will also rotate, so that the stainless steel pipe fitting 2 can be laser cut at different angles.

[0022] The telescopic mechanism 22 includes a contraction tube 24, and the end of the connecting column 25 is rotatably installed at the front end of the contraction tube 24. The telescopic mechanism 22 can drive the connecting column 25 to perform linear telescopic movement, so that the connecting column 25 can drive the outer tube 9 to move linearly on the surface of the inner tube 17, ensuring that the outward expansion positioning mechanism 8 can operate normally. A second gear assembly 32 is provided on one side of the contraction tube 24. The second gear assembly 32 includes a second driven gear 28 and a second driving gear 29. The second driving gear 29 is arranged above the second driven gear 28, and the second driving gear 29 is meshed with the second driven gear 28. A handle 30 is provided on the outer surface of the moving frame 7. The center of the handle 30 is connected to the second driving gear 29 through a connecting rod. When the staff manually rotates the handle 30, the second driving gear 29 can drive The second driven gear 28 is driven to rotate, and a threaded rod 27 is installed at the center of the second driven gear 28. A threaded groove 26 is arranged inside the shrinking tube 24. The surface thread of the threaded rod 27 is installed in the threaded groove 26. When the second driven gear 28 rotates, the threaded rod 27 also rotates. Under the action of the threaded groove 26, the position of the shrinking tube 24 can be moved. At this time, the shrinking tube 24 can drive the connecting column 25 to realize the control of the outer tube 9. A bracket 23 is arranged below the telescopic mechanism 22, and a linear slider 36 is installed at the bottom of the shrinking tube 24. A linear slide groove 35 is arranged on the upper surface of the bracket 23. The linear slider 36 is slidably installed in the linear slide groove 35. Under the action of the bracket 23, the stability of the shrinking tube 24 during movement can be guaranteed, thereby improving the use quality of the device.

[0023] Four limit strips 18 are evenly arranged on the outer surface of the inner tube 17, and a limit groove matching the limit strip 18 is arranged inside the outer tube 9. The limit strip 18 is slidably engaged in the limit groove. Under the cooperation of the limit strip 18 and the limit groove, the position of the outer tube 9 can be restricted. The outer tube 9 can only slide in a straight line on the surface of the inner tube 17 and will not rotate.

[0024] A bottom slide groove 33 is arranged on the surface of the auxiliary slide 6, and a roller 34 is arranged on the surface of the bottom of the movable frame 7. The roller 34 is close to the surface of the bottom slide groove 33. Under the action of the roller 34, when the positioning sliding mechanism 4 drives the stainless steel pipe fitting 2 to move, the stainless steel pipe fitting 2 can drive the movable frame 7 to move because the outward expansion positioning mechanism 8 fixes and clamps the inside of the stainless steel pipe fitting 2. At this time, the laser cutting body 1 can perform laser cutting at different positions of the stainless steel pipe fitting 2, while also ensuring the stability of the stainless steel pipe fitting 2 during laser cutting.

[0025] The power supply frequency of the stepper motor 21 is the same as that of the positioning sliding mechanism 4. The power supply frequency received by the stepper motor 21 and the positioning sliding mechanism 4 is the same, so that the stepper motor 21 and the positioning sliding mechanism 4 can operate at a synchronized speed. At this time, the positioning sliding mechanism 4 and the movable frame 7 can move synchronously and in the same direction, thereby realizing laser cutting of different positions of the stainless steel pipe 2.

[0026] The outward expansion positioning mechanism 8, the positioning sliding mechanism 4, and the clamping mechanism 5 are in the same straight line, which can ensure that the stainless steel pipe 2 can be clamped by the outward expansion positioning mechanism 8, the positioning sliding mechanism 4, and the clamping mechanism 5 in sequence, ensuring the stability of the stainless steel pipe 2 during laser cutting.

[0027] Working principle: First, the laser cutting body 1, the main body slide 3, the positioning sliding mechanism 4, and the clamping mechanism 5 are combined into a laser cutting device. The stainless steel pipe 2 is passed through the positioning sliding mechanism 4 and the clamping mechanism 5 in sequence. The positioning sliding mechanism 4 and the clamping mechanism 5 can clamp the surface of the stainless steel pipe 2, and the positioning sliding mechanism 4 and the clamping mechanism 5 can control the stainless steel pipe 2 to rotate. Since this structure is an existing mechanism, it will not be elaborated here. Then the end of the stainless steel pipe 2 is sleeved on the surface of the support plate 12, and the staff manually rotates the handle 30, and the second driving gear 29 can drive the second driven gear 28 to rotate. When the second driven gear 28 rotates, the threaded rod 27 will also rotate. Under the action of the thread groove 26, the position of the shrinking tube 24 can move. At this time, the shrinking tube 24 can drive the connecting column 25, thereby realizing the control of the outer tube 9. Then, when the outer tube 9 moves on the surface of the inner tube 17 When one side of the mobile frame 7 moves, the end of the connecting strip 11 close to the outer tube 9 will also move toward the side of the mobile frame 7. At the same time, since the support plate 12 is slidably engaged in the T-shaped slide groove 15 through the T-shaped slider 16, the connecting strip 11 and the cross fixing frame 14 gradually tend to be parallel, thereby achieving the effect of supporting the support plate 12 outward, so that the support plate 12 can expand and clamp the inner wall of the stainless steel pipe fitting 2 outward, so that when the stainless steel pipe fitting 2 is suspended for a long length, the end head of the stainless steel pipe fitting 2 can be expanded and clamped outward, so that the stainless steel pipe fitting 2 will not vibrate or deform during processing, thereby improving the quality of laser cutting of the stainless steel pipe fitting 2. Finally, the power supply frequency received by the stepping motor 21 is the same as that received by the positioning sliding mechanism 4, so that the stepping motor 21 and the positioning sliding mechanism 4 can be operated at a synchronous speed. At this time, the positioning sliding mechanism 4 and the mobile frame 7 can move synchronously and in the same direction, and laser cutting can be performed on the stainless steel pipe fitting 2 at different angles and different positions.
