[0003] When traditional laser pipe cutting machines clamp pipes, most of them use a structure that drives a rack with a cylinder to clamp the pipes. However, this method has low precision, slow response speed, and is affected by the air pressure stability, and cannot meet the current needs of high-precision and rapid clamping and cutting of pipes. Summary of the Utility Model

[0004] In view of the deficiencies of the existing technology, the purpose of the present utility model is to provide a pipe clamping and transferring mechanism and a laser pipe cutting machine to solve the technical problems mentioned in the above background technique.

Two first rods are fixedly penetrated through the top of one of the U-shaped frames. The upper half of the outer peripheral surface of the first rod is rotatably sleeved with a fixed roller. Two second rods are rotatably penetrated through the top of the other U-shaped frame. The upper half of the outer peripheral surface of the second rod is fixedly sleeved with a driving roller. The fixed roller and the driving roller are at the same height, and a transferring unit is arranged on one side of the U-shaped frame.

[0008] By adopting the above technical solutions, the forward and reverse rotation of the servo motor realizes the approach and separation of the fixed roller and the driving roller, thereby realizing the clamping and loosening of the pipe, with high precision, durability, fast response speed, and not affected by unstable air pressure.

[0009] Further, the transfer unit includes an extension plate fixedly connected to the inner bottom wall of the corresponding C-shaped frame. A motor is fixedly connected to the top of the extension plate. The output end of the motor rotates through the extension plate, and the output end of the motor is drivingly connected to both of the second rods through a belt.

Detailed implementation mode

[0022] The following further elaborates on the present utility model in conjunction with the attached drawings.

[0023] Embodiment 1:

[0024] Referring to Figures 1 to 4 , a pipe clamping and transferring mechanism disclosed by the present utility model includes a pipe placement rack 1. A placement plate 2 is fixedly connected inside the pipe placement rack 1. The pipe is placed on the top of the placement plate 2. A fixed housing 3 is fixedly connected near one end of the top of the pipe placement rack 1. A servo motor 4 is fixedly connected to one side of the fixed housing 3. The output end of the servo motor 4 is drivingly connected to a lead screw 5. The lead screw 5 rotates through the fixed housing 3. Two threads with opposite helix directions are provided on the outer peripheral surface of the lead screw 5. And two sliders 6 are threadedly connected to both threads on the outer peripheral surface of the lead screw 5. Two linear tracks 7 are fixedly connected to the inner bottom wall of the fixed housing 3. The slider 6 is slidably connected to both linear tracks 7. A clamping and transferring part 8 is arranged above the slider 6.

[0025] In this embodiment, the fixed housing 3 is provided with an open top and is located below the pipe. The linear tracks 7 limit the slider 6 so that the slider 6 can only move linearly. When the servo motor 4 works, it drives the lead screw 5 to rotate. The rotation of the lead screw 5 drives the two sliders 6 to move in opposite directions, and the distances between the two sliders 6 and the pipe are always the same.

[0026] In a further preferred embodiment of the present utility model, as shown in Figure 3 and Figure 4 , the clamping and transferring part 8 includes a C-shaped frame 81 fixedly connected to the top of the slider 6. Two first rods 82 are fixedly penetrated through the top of one of the C-shaped frames 81. A fixed roller 83 is rotatably sleeved on the upper half of the outer peripheral surface of the first rod 82. Two second rods 84 are rotatably penetrated through the top of the other C-shaped frame 81. A driving roller 85 is fixedly sleeved on the upper half of the outer peripheral surface of the second rod 84. The fixed roller 83 and the driving roller 85 are at the same height, and a transfer unit 86 is arranged on one side of the C-shaped frame 81.

[0027] In this embodiment, the pipe is inserted between the fixed roller 83 and the driving roller 85. The servo motor 4 works to drive the two sliders 6 to move towards each other until both the fixed roller 83 and the driving roller 85 are in contact with the pipe to clamp the pipe.

[0028] The outer peripheral surfaces of the fixed roller 83 and the driving roller 85 are made of rubber material to prevent the pipe from being scratched, and to increase the friction with the pipe, resulting in a better clamping effect and a better transfer effect.

[0029] In a further preferred embodiment of the present utility model, as Figure 3 and Figure 4 shown, the transfer unit 86 includes an extension plate 87 fixedly connected to the inner bottom wall of the corresponding U-shaped frame 81. A motor 88 is fixedly connected to the top of the extension plate 87. The output end of the motor 88 rotates through the extension plate 87, and the output end of the motor 88 is in transmission connection with both of the two second rods 84 through a belt.

[0030] In this embodiment, after the pipe is clamped inside, the motor 88 works to drive the two second rods 84 to rotate. The rotation of the second rods 84 drives the two driving rollers 85 to rotate in the same direction. Under the action of the friction force between the driving roller 85 and the pipe, the pipe is driven to move linearly.

[0031] In a further preferred embodiment of the present utility model, as Figure 2 shown, a placement groove 9 is formed at the top of the placement plate 2. The pipe is placed in the placement groove 9.

[0032] In this embodiment, the lower half of the outer wall of the pipe is in contact with the inner wall of the placement groove 9. The placement groove 9 limits the pipe to ensure that the pipe is located at the center of the two sliders 6.

[0033] The implementation principle of the above embodiment is as follows:

[0034] The pipe is placed in the placement groove 9, and a part of the pipe is located between the fixed roller 83 and the driving roller 85. Then the servo motor 4 is started. The servo motor 4 works to drive the lead screw 5 to rotate. The rotation of the lead screw 5 drives the two sliders 6 to move towards each other until both the fixed roller 83 and the driving roller 85 are in contact with the pipe to clamp the pipe.

[0035] Then the motor 88 works to drive the two second rods 84 to rotate. The rotation of the second rods 84 drives the two driving rollers 85 to rotate in the same direction. Under the action of the friction force between the driving roller 85 and the pipe, the pipe is driven to move linearly.

[0036] Embodiment 2:

[0037] Refer to Figures 1 to 4A laser tube cutting machine includes the tube clamping and transferring mechanism of Example 1, and also includes a support frame 10, the support frame 10 is fixedly connected to one end of the tube placement frame 1 close to the fixed shell 3, and a laser cutting device 11 is fixedly connected to the top of the support frame 10, and the tube part is inserted into the laser cutting device 11.

[0038] In this embodiment, the motor 88 works to transfer the pipe to the laser cutting device 11, and the laser cutting device 11 cuts the pipe. The laser cutting device 11 is a common device for pipe cutting, and will not be described in detail here.

[0039] The embodiments of this specific implementation method are all preferred embodiments of the utility model, and are not intended to limit the protection scope of the utility model. Therefore, all equivalent changes made based on the structure, shape, and principle of the utility model should be included in the protection scope of the utility model.
