[0029] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0030] See also Figure 1-Figure 3 In an embodiment of the present invention, a four-chuck laser tube cutting machine includes a fixed base 1, a chuck 2 is axially slidably mounted on the outer wall of the fixed base 1, a tray 3 is vertically slidably mounted on the outer wall of the fixed base 1, and a transmission mechanism 4 is arranged on the tray 3 and the fixed base 1;

[0031] The transmission mechanism 4 includes a transmission unit and a force-bearing unit;

[0032] The transmission unit is used to provide thrust for the vertical movement of the tray 3;

[0033] The force-bearing unit is used to transmit power to the activities of the transmission unit;

[0034] The force-bearing unit includes a force-bearing block 401, a stop block 406, a positioning rod 407, and a spring 408;

[0035] The force block 401 is axially slidably mounted on the outer wall of the fixing base 1, and the force block 401 is used to synchronously drive the transmission rod 402 to move;

[0036] The stopper 406 is laterally slidably mounted on the inner wall of the force-bearing block 401 and extends to the outside of the force-bearing block 401. The stopper 406 is used to receive the moving thrust from the chuck 2.

[0037] The positioning rod 407 is fixed to the outer wall of the block 406 and extends through the inner wall of the force-bearing block 401. The positioning rod 407 is used to provide guidance for the lateral movement of the block 406.

[0038] The two ends of the spring 408 are respectively clamped on the inner wall of the force-bearing block 401 and the outer wall of the stop block 406. The spring 408 is used to provide an elastic thrust in one direction for the stop block 406.

[0039] The transmission unit includes a transmission rod 402, a guide rod 403, a movable plate 404, and a guide groove 405;

[0040] The transmission rod 402 is fixed to the outer wall of the force-bearing block 401 and is located inside the fixing seat 1. The transmission rod 402 is used to synchronously drive the guide rod 403 to move axially;

[0041] The guide rod 403 is fixed to the outer wall of the transmission rod 402 and is used to give thrust to the guide groove 405;

[0042] The movable plate 404 is vertically slidably mounted on the inner wall of the fixed base 1 and extends to the outer wall of the fixed base 1. The movable plate 404 is used to synchronously drive the tray 3 to move vertically;

[0043] The guide groove 405 is formed on the inner wall of the movable plate 404 , and the guide groove 405 is used to synchronously drive the movable plate 404 to move vertically.

[0044] In this embodiment: when it is necessary to perform a blanking operation on the cut pipe, the chuck 2 holding the pipe is moved to the required position by moving the chuck 2. During the movement of the chuck 2, the outer wall of the chuck 2 will contact the outer wall of the block 406. At this time, the block 406 will be pushed by the chuck 2 and move synchronously with the chuck 2. The synchronously moving chuck 2 will synchronously drive the force block 401 and the transmission rod 402 to move, so that the guide rod 403 fixed on the outer wall of the transmission rod 402 moves with the movement of the transmission rod 402. The moving guide rod 403 will give a thrust to the guide groove 405, so that the guide groove 405 is stressed. Since the outer wall of the guide groove 405 is in an inclined state as a whole, the guide groove 405 will transmit the moving thrust to the movable plate 404, so that the movable plate 404 moves vertically. The vertically moving movable plate 404 synchronously drives the tray 3 to move, The disc 3 moves from the bottom of the chuck 2 to between the two chucks 2 and is located below the pipe. At this time, the chuck 2 is loosened to allow the pipe to fall on the upper surface of the tray 3. At this time, the chuck 2 still provides support for the pipe without providing clamping limit. Then, when the chucks 2 continue to move away from each other under the action of the driving unit, the pipe will gradually separate from the chuck 2, and the tray 3 will be subjected to the downward pressure from the pipe at this time. Then the block 406 will also be subjected to the relative extrusion force from the chuck 2, causing the block 406 to enter the interior of the force block 401, and the inner side of the chuck 2 will also gradually separate from the outer wall of the pipe. When the pipe is completely separated from the inner side of the chuck 2, the tray 3 will move downward back to its original position under the pressure of the pipe, causing the pipe to move synchronously, and the pipe is guided along the outer wall of the tray 3 to the unloading area, completing the automatic unloading operation of the pipe, reducing the driving unit and further improving work efficiency.

[0045] Please refer to Figure 1-Figure 3 The inner wall of the guide groove 405 matches the outer wall of the guide rod 403, and the outer wall of the guide groove 405 is tilted as a whole. The inner wall of the fixed seat 1 is formed with a slide groove for the vertical movement of the movable plate 404, and the inner wall of the fixed seat 1 is formed with a slide groove for the axial movement of the transmission rod 402. The inner wall of the force block 401 is formed with a slide groove for the axial movement of the positioning rod 407 and the block 406. The outer wall of the end of the block 406 is tilted, and the position of the block 406 coincides with the moving trajectory of the chuck 2.

[0046] In this embodiment: through this structure, when the chuck 2 moves axially, the chuck 2 closest to the stop block 406 will simultaneously give axial thrust to the stop block 406, the transmission rod 402, and the force block 401, so that the tray 3 moves between the two chucks 2 and under the pipe.

[0047] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
