[0014] The use of the tube laser cutting machine is as follows: S1: The external pipe feeding equipment pushes the pipe into the guide sleeve used to support the pipe, connects the external oil tank and the oil pump inlet pipe, and the user controls the oil pump to start. The oil pump sends the oil into the ring groove of the support plate. At this time, the oil in the ring groove of the support plate will enter the inlet pipe of the oil cylinder clamping claw under the blocking effect of the sealing ring, so that the clamping claw at the bottom moving end of the oil cylinder clamping claw moves, thereby clamping the pipe. Then the servo motor is started, and the servo motor drives the rotating frame to rotate through the moving sleeve and the first gear. The rotating frame drives the pipe to rotate through the oil cylinder clamping claw. During this process, the laser head starts to cut the pipe; S2: After the pipe is cut, the control electric cylinder in the device will drive the support plate to move, and the support plate will drive the cut pipe part to move synchronously through the sealing ring and the rotating frame, so that the cut pipe is away from the remaining pipe to be cut, until the support plate drives the trigger rod to move below the resistance block, and the control electric cylinder is closed. During this process, the resistance block will push the trigger rod to move vertically downward, and the trigger rod will drive the pressure plate to move synchronously. Since the convex shaft end of the pressure plate is fitted and embedded in the inclined groove of the thrust frame, the pressure plate will push the thrust frame to move horizontally at this time, and the movable sleeve connected to the bottom end of the thrust frame will drive the first gear and the second gear to move horizontally synchronously. At this time, the first gear will be away from the gear ring inside the rotating frame to release the transmission relationship, and at the same time, the second gear will form a meshing transmission relationship with the third gear, so that the servo motor can drive the third gear to rotate; S3: The rotating third gear will drive the transmission rod to rotate in the fixed sleeve. At this time, the threaded groove on the transmission rod will drive the corresponding moving ring to move. The two moving rings will approach each other. At the same time, the moving ring will push the main pressure plate to move through the moving plug rod, the oil cylinder and the pressure spring. When the main pressure plate contacts the inner wall of the pipe body, the main pressure plate will drive the first grinding block to move synchronously through the auxiliary pressure plate, and the two second grinding blocks on the first grinding block will follow the movement. At this time, the pipe mouth of the pipe body that needs to be polished will be between the two second grinding blocks. S4: The moving ring continues to move, so that the plug body of the moving plug rod can press out the oil in the oil cylinder. At the same time, the pressure spring will be compressed, and the oil in the oil cylinder will enter the pressure cylinder through the infusion tube, the connecting sleeve, the flow channel and the infusion sleeve in turn. At this time, the oil in the pressure cylinder will push the thrust plug rod to move, and the thrust plug rod will push the first grinding block to move toward the pipe mouth of the pipe through the moving plate and the guide block. During this process, the auxiliary pressure plate will shrink and move on the main pressure plate. When the first grinding block drives the second grinding block to press against the pipe mouth, the inclined surface of the second grinding block will first contact and be compressed with the pipe mouth of the pipe. At this time, the second grinding block drives the sliding block to move synchronously through the limit plate, so that the sliding block compresses the spring in the first grinding block. When the side wall of the first grinding block contacts the end face of the pipe mouth, the two second grinding blocks will fit on the inner and outer sides of the pipe mouth. S5: Then control the electric cylinder to start again, so that the support plate moves away from the guide sleeve again. At this time, the trigger rod will pass through the resistance block. Under the action of the slide groove on the inner wall of the loading cylinder, the trigger rod will move upward and reset, so that the first gear can form a transmission relationship with the gear ring on the inner side of the rotating frame again. At this time, the servo motor can drive the rotating frame to rotate again, and the rotating frame drives the pipe to rotate through the cylinder clamping claw. At this time, the first grinding block and the second grinding block can grind the burrs on the pipe port, and the main pressure plate and the auxiliary pressure plate can grind the inner wall of the pipe. After grinding, the electric cylinder is controlled to push the support plate to move again. The trigger rod moves, and enters under the resistance block again. Then the servo motor rotates in the opposite direction to reset the deformation mechanism as a whole. At this time, the first grinding block and the second grinding block are away from the pipe. Finally, the electric cylinder is controlled to drive the cylinder clamping claw to move toward the end of the unloading plate through the support plate and the rotating frame. At the same time, the oil pump extracts a small amount of oil in the cylinder clamping claw, so that the cylinder clamping claw no longer clamps the pipe. At this time, when the pipe mouth contacts the unloading plate, the unloading plate will block the movement of the pipe, while the cylinder clamping claw, the support plate and the fixed sleeve continue to move. Therefore, the processed pipe will be discharged along the clamping claw of the cylinder clamping claw.

[0015] Compared with the prior art, the beneficial effects of the present invention are: the automatic tube laser cutting machine and the method of use can grind the burrs generated at the tube mouth after laser cutting during use, and can also grind the inner wall of the tube, thereby effectively reducing the subsequent processing workload of the tube. The specific contents are as follows: 1. A deformation mechanism is installed in the middle of the fixed sleeve, and the deformation mechanism includes a moving ring. The moving rings are symmetrically distributed on both sides of the middle of the transmission rod. Two thread grooves with opposite rotation directions are arranged in the middle of the transmission rod. The thread grooves of the transmission rod are threadedly connected with corresponding moving rings. The upper and lower sides of the moving ring are rotatably connected with corresponding moving plug rods. The top of the oil cylinder is rotatably connected to the middle inner wall of the main pressure plate. At the same time, corresponding auxiliary pressure plates are slidably inserted at both ends of the main pressure plate. When the transmission rod rotates, the two moving rings will move synchronously on the fixed sleeve. The moving ring drives the corresponding main pressure plate to move through the moving plug rod and the oil cylinder, so that the outer walls of the main pressure plate and the auxiliary pressure plate can fit on the inner wall of the pipe, so as to facilitate the subsequent inner wall grinding; 2. The end of the auxiliary pressure plate is fixedly connected to the first grinding block, and a symmetrically distributed second grinding block is fitted on the side of the top of the first grinding block away from the guide block, and the inclined surface of the end of the second grinding block is set towards the main pressure plate, and the outer walls of the two second grinding blocks are fixedly connected to the limiting plates on both sides, the limiting plates are on the outsides of the two auxiliary pressure plates, and the end of the limiting plate away from the second grinding block is fixedly connected to the corresponding sliding block, and the end of the limiting plate is slidably fitted in the vertical groove of the first grinding block, and the bottom surface of the sliding block and the inner wall of the first grinding block are elastically connected by a spring. When the first grinding block drives the second grinding block to press against the pipe orifice, the end face of the pipe orifice will contact the inclined surface of the second grinding block, so that the second grinding block drives the sliding block to move synchronously through the limiting plate. At this time, the sliding block will compress the spring, so that the first grinding block can contact the end face of the pipe orifice, and the second grinding block can fit on both sides of the inner and outer sides of the pipe orifice.

Since the convex shaft end of the pressure plate 19 is fitted and embedded in the inclined groove 18 of the thrust frame 17, the pressure plate 19 will push the thrust frame 17 to move horizontally at this time, and the movable sleeve 14 rotatably connected to the bottom end of the thrust frame 17 will drive the first gear 13 and the second gear 15 to move horizontally synchronously. At this time, the first gear 13 will be away from the gear ring inside the rotating frame 9 to release the transmission relationship, and at the same time, the second gear 15 will form a meshing transmission relationship with the third gear 22, so that the servo motor 16 can drive the third gear 22 to rotate; S3: The rotating third gear 22 will drive the transmission rod 23 to rotate in the fixed sleeve 24. At this time, the threaded groove on the transmission rod 23 will drive the corresponding moving ring 2501 to move, and the two moving rings 2501 will approach each other. At the same time, the moving ring 2501 will push the main pressure plate 2505 to move through the moving plug rod 2502, the oil cylinder 2503 and the pressure spring 2504. When the main pressure plate 2505 is in contact with the inner wall of the tube body, the main pressure plate 2505 will drive the first grinding block 32 to move synchronously through the auxiliary pressure plate 2506, and the two second grinding blocks 33 on the first grinding block 32 will move accordingly. At this time, the pipe mouth of the tube body that needs to be polished will be between the two second grinding blocks 33; S4: The moving ring 2501 continues to move, so that the plug body of the moving plug rod 2502 can press out the oil in the oil cylinder 2503, and at the same time the pressure spring 2504 will be compressed, and the oil in the oil cylinder 2503 will pass through the infusion tube 2507, the connecting sleeve 2508, the flow channel 26 and the infusion sleeve 27 in sequence to enter the pressure cylinder 28. At this time, the oil in the pressure cylinder 28 will push the thrust plug rod 29 to move, and the thrust plug rod 29 will push the first grinding block 32 to the pipe mouth of the pipe through the moving disk 30 and the guide block 31. During the process, the auxiliary pressure plate 2506 will shrink and move on the main pressure plate 2505. When the first grinding block 32 drives the second grinding block 33 to press against the pipe mouth, the inclined surface of the second grinding block 33 will first contact and be pressed against the pipe mouth. At this time, the second grinding block 33 drives the sliding block 35 to move synchronously through the limit plate 34, so that the sliding block 35 compresses the spring in the first grinding block 32. When the side wall of the first grinding block 32 contacts the end face of the pipe mouth, the two second grinding blocks 33 will fit on the inner and outer sides of the pipe mouth. S5: Then control the electric cylinder 6 to start again, so that the support plate 7 moves away from the guide sleeve 3 again. At this time, the trigger rod 20 will pass through the resistance block 21. Under the action of the inner wall groove of the loading tube 5, the trigger rod 20 will move upward and reset, so that the first gear 13 can form a transmission relationship with the gear ring inside the rotating frame 9 again. At this time, the servo motor 16 can drive the rotating frame 9 to rotate again, and the rotating frame 9 drives the pipe to rotate through the cylinder clamping claw 10. At this time, the first grinding block 32 and the second grinding block 33 can grind the burrs on the pipe port, and the main pressure plate 2505 and the auxiliary pressure plate 2506 can grind the inner wall of the pipe. After grinding, control the electric cylinder 6 to push the support plate 7 to move again. The trigger rod 20 enters under the resistance block 21 again, and then the servo motor 16 rotates in the opposite direction, so that the deformation mechanism 25 is reset as a whole. At this time, the first grinding block 32 and the second grinding block 33 are away from the pipe. Finally, the electric cylinder 6 is controlled to drive the cylinder clamping claw 10 to move toward the end of the unloading plate 12 through the support plate 7 and the rotating frame 9. At the same time, the oil pump 11 extracts a small amount of oil in the cylinder clamping claw 10, so that the cylinder clamping claw 10 no longer clamps and fixes the pipe. At this time, when the pipe mouth and the unloading plate 12 are in contact, the unloading plate 12 will block the movement of the pipe, and the cylinder clamping claw 10, the support plate 7 and the fixed sleeve 24 continue to move, so the processed pipe will be discharged along the clamping claw of the cylinder clamping claw 10.

The oil pump (11) sends oil into the annular groove of the support plate (7). At this time, the oil in the annular groove of the support plate (7) will enter the inlet pipe of the cylinder clamping claw (10) under the blocking effect of the sealing ring (8), so that the clamping claw at the bottom movable end of the cylinder clamping claw (10) moves, thereby clamping the pipe. Then, the servo motor (16) is started. The servo motor (16) drives the rotating frame (9) to rotate through the movable sleeve (14) and the first gear (13). The rotating frame (9) drives the pipe to rotate through the cylinder clamping claw (10). During this process, the laser head (4) starts to cut the pipe. S2: After the pipe is cut, the control electric cylinder (6) in the device will drive the support plate (7) to move, and the support plate (7) drives the cut pipe part to move synchronously through the sealing ring (8) and the rotating frame (9), so that the cut pipe is away from the remaining pipe to be cut, until the support plate (7) drives the trigger rod (20) to move below the resistance block (21), and the control electric cylinder (6) is closed. During this process, the resistance block (21) will push the trigger rod (20) to move vertically downward, and the trigger rod (20) will drive the pressure plate (19) to move synchronously. The end of the convex shaft of the (19) is fitted and embedded in the inclined groove (18) of the thrust frame (17). At this time, the pressure plate (19) will push the thrust frame (17) to move horizontally, and the movable sleeve (14) connected to the bottom end of the thrust frame (17) will drive the first gear (13) and the second gear (15) to move horizontally synchronously. At this time, the first gear (13) will move away from the gear ring inside the rotating frame (9) to release the transmission relationship, and at the same time, the second gear (15) will form a meshing transmission relationship with the third gear (22), so that the servo motor (16) can drive the third gear (22) to rotate; S3: The rotating third gear (22) drives the transmission rod (23) to rotate in the fixed sleeve (24). At this time, the threaded groove on the transmission rod (23) drives the corresponding moving ring (2501) to move. The two moving rings (2501) will approach each other. At the same time, the moving ring (2501) will push the main pressure plate (2505) to move through the moving plug rod (2502), the oil cylinder (2503) and the pressure spring (2504). When the main pressure plate (2505) contacts the inner wall of the tube body, the main pressure plate (2505) drives the first grinding block (32) to move synchronously through the auxiliary pressure plate (2506). The two second grinding blocks (33) on the first grinding block (32) move accordingly. At this time, the pipe mouth of the tube body to be polished will be between the two second grinding blocks (33); S4: The moving ring (2501) continues to move, so that the plug body of the moving plug rod (2502) can press out the oil in the oil cylinder (2503). At the same time, the pressure spring (2504) will be compressed, and the oil in the oil cylinder (2503) will pass through the infusion tube (2507), the connecting sleeve (2508), the flow channel (26) and the infusion sleeve (27) in sequence to enter the pressure cylinder (28). At this time, the oil in the pressure cylinder (28) will push the thrust plug rod (29) to move, and the thrust plug rod (29) will push the first grinding block (32) toward the pipe through the moving disk (30) and the guide block (31). The pipe mouth is moved, during which the auxiliary pressure plate (2506) will shrink and move on the main pressure plate (2505). When the first grinding block (32) drives the second grinding block (33) to press against the pipe mouth, the inclined surface of the second grinding block (33) will first contact and be pressed against the pipe mouth. At this time, the second grinding block (33) drives the sliding block (35) to move synchronously through the limit plate (34), so that the sliding block (35) compresses the spring in the first grinding block (32). When the side wall of the first grinding block (32) contacts the end face of the pipe mouth, the two second grinding blocks (33) will fit on the inner and outer sides of the pipe mouth. S5: Then the electric cylinder (6) is controlled to start again, so that the support plate (7) moves away from the guide sleeve (3) again. At this time, the trigger rod (20) passes through the abutment block (21). Under the action of the inner wall groove of the loading tube (5), the trigger rod (20) moves upward and resets, so that the first gear (13) can form a transmission relationship with the gear ring inside the rotating frame (9) again. At this time, the servo motor (16) can drive the rotating frame (9) to rotate again, and the rotating frame (9) drives the pipe to rotate through the cylinder clamping claw (10). At this time, the first grinding block (32) and the second grinding block (33) can grind the burrs on the pipe end, and the main pressure plate (2505) and the auxiliary pressure plate (2506) can grind the inner wall of the pipe. After the grinding is completed, the electric cylinder (6) is controlled to push the support plate (7) to move again, and the trigger motor (16) can drive the rotating frame (9) to rotate again. The launching rod (20) enters below the abutment block (21) again, and then the servo motor (16) rotates in the opposite direction, so that the deformation mechanism (25) is reset as a whole. At this time, the first grinding block (32) and the second grinding block (33) are away from the pipe. Finally, the electric cylinder (6) is controlled to drive the cylinder clamping claw (10) to move toward the end of the discharge plate (12) through the support plate (7) and the rotating frame (9). At the same time, the oil pump (11) extracts a small amount of oil in the cylinder clamping claw (10), so that the cylinder clamping claw (10) no longer clamps and fixes the pipe. At this time, when the pipe mouth and the discharge plate (12) are in contact, the discharge plate (12) will block the movement of the pipe, while the cylinder clamping claw (10), the support plate (7) and the fixing sleeve (24) continue to move, so that the pipe that has been processed will be discharged along the clamping claw of the cylinder clamping claw (10).
