Description

Technical Field

[0001] The utility model relates to the technical field of pipe cutting support, in particular to a pipe cutting auxiliary support device. Background Technique

[0002] A pipe cutting machine is a device for cutting pipes, including functions such as material clamping, knife feeding, material feeding, size setting, fixed-number stop, and work measurement. It also drives the pipe fittings to rotate during the pipe cutting process. Especially for the cutting of long-round pipes, under the action of its own gravity, there will be a drooping situation. After retrieval, the patent with the publication number of CN108127275B discloses a laser pipe cutting machine auxiliary support device, which includes a plurality of cams. The plurality of cams are driven by a set of driving devices to rotate in the same direction and at the same speed as the pipe to be processed. The acting points on the cam curves of each cam are in contact with a cylinder seat. A cylinder is installed on each cylinder seat, and a flat tray is provided at the end of the cylinder rod of the cylinder. The flat tray is used to support the pipe; each cylinder seat is installed on a guide rod, a spring is sleeved on the guide rod, and the cylinder seat is installed on the spring. When in use, the cam curve is used to adapt to the change of the lowest point position of the pipe during rotation, and it is used for the cutting process of rectangular pipes; the auxiliary support of the present invention shares the power with the front chuck and moves synchronously; the cylinders and springs of the present invention cooperate to ensure that the cams rotate flexibly and the pipes are accurately positioned at the same time; when the auxiliary support of the present invention is not needed, it does not affect the integrity of the original structure of the machine. However, since it shares the power with the front chuck in the pipe cutting machine, it needs to be directly connected to the pipe cutting machine, which will cause a certain restraint on the pipe cutting machine body, resulting in difficulties in handling and placing the pipe cutting machine body. Therefore, a pipe cutting auxiliary support device that is independent of the pipe cutting machine and can rotate and move forward and backward along with the pipe, shares the weight for the chuck of the pipe cutting machine, and is convenient to move is designed.

[0016] The pipe cutting auxiliary support device facilitates the support of the side of the pipe away from the pipe cutting machine through a clamping ring. During use, the pipe can pass through the clamping ring. When the pipe cutting machine feeds the material, under the action of the friction force between the pipe and the bottom of the clamping ring, the clamping ring is simultaneously dragged to move back and forth on the support frame. And even when cutting the pipe, under the action of the friction force between the pipe and the bottom of the clamping ring, the clamping ring can be driven to rotate simultaneously. By setting the moving block and the adhering type lifting and positioning mechanism, it is convenient to adjust within a narrow height difference. When the clamping ring slides to the end, the adhering type lifting and positioning mechanism can rise to be clamped in the positioning groove, and the moving block drives the clamping ring to quickly move to the other end to continue the pipe cutting auxiliary support. It can be used for positioning adjustment in the bridge gap with a narrow height difference. The pipe cutting auxiliary support device is independent of the pipe cutting machine and can rotate and move back and forth following the pipe, which is convenient to move. Compared with the traditional three-chuck, it has the advantages of low manufacturing cost and low failure rate. It is especially suitable for long and heavy pipes and can play a role in weighing for processing heavy pipes and sharing the weight for the chuck of the pipe cutting machine.

Detailed implementation manners

[0026] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0027] Embodiment:

[0028] Please refer to Figure 1-8 , a pipe cutting auxiliary support device, including a support frame 1, a sliding seat 4 with a snap ring 2 having a self-rotation function at the top is horizontally slidably matched with the top of the support frame 1. There is a bridge gap between the support frame 1 and the sliding seat 4. A movable block 6 that can move back and forth is arranged at the bottom of the bridge gap. A sticking type lifting and positioning mechanism is arranged at the top of the movable block 6, and a positioning groove 20 adapted to the sticking type lifting and positioning mechanism is arranged at the bottom of the sliding seat 4.

[0029] Specifically, the sticking type lifting and positioning mechanism includes two articulated rods 10 with their ends articulated to each other. Fixed blocks 9 and push-pull blocks 8 are respectively articulated to the free ends of the two articulated rods 10. The fixed block 9 is fixedly connected to the movable block 6, and the push-pull block 8 is slidably matched with the movable block 6. A positioning snap frame 11 adapted to the positioning groove 20 is rotatably connected at the articulated part of the two articulated rods 10. It also includes a feeding component for driving the push-pull block 8 to feed towards the fixed block 9 side. Through feeding and taking parts, through the cooperation of the push-pull block 8, the fixed block 9 and the two articulated rods 10, it is convenient to adjust the lifting of the positioning snap frame 11. The positioning snap frame 11 can be snapped into the positioning groove 20 from below, and the positions of the sliding seat 4 and the snap ring 2 as a whole can be locked. By quickly moving the movable block 6, the snap ring 2 can be driven to move to one end far from the pipe cutting machine side.

[0030] Specifically, the feeding component includes a driving cylinder 7 fixedly installed on the movable block 6. The output shaft of the driving cylinder 7 is fixedly connected to the push-pull block 8. It also includes a guide bar 12 that is slidably guided with the push-pull block 8. The guide bar 12 is fixedly connected to the movable block 6. Starting the driving cylinder 7 is convenient to drive the push-pull block 8 to reciprocate towards the fixed block 9 side. Through the arrangement of the guide bar 12, the push-pull block 8 can be guided, and the moving stability of the push-pull block 8 is increased.

[0031] Specifically, it also includes a mobile driving mechanism for driving the moving block 6 to move forward and backward. The mobile driving mechanism includes a screw 13 and a guide rod 14 arranged in the gap between the bridges. Both ends of the screw 13 and the guide rod 14 are rotatably connected to the support frame 1 through a mounting seat 15. It also includes a driving member for driving the screw 13 to rotate. The moving block 6 is threadedly connected to the screw 13 and is guided and slidably matched with the guide rod 14. Through the driving member, it is easy to drive the screw 13 to rotate clockwise or counterclockwise. Through the guided sliding match of the guide rod 14, it is easy to drive the moving block 6 to move forward or backward in the gap between the bridges.

[0032] Specifically, the driving member includes a fixed frame 17 fixedly mounted on one of the mounting seats 15, and the screw 13 is rotatably connected to the fixed frame 17. It also includes a driving motor 16 fixedly mounted on the support frame 1 below the gap between the bridges. The output shaft of the driving motor 16 is connected to the screw 13 through a synchronous belt 18. When the driving motor 16 is started, the output shaft of the driving motor 16 rotates clockwise or counterclockwise. Through the transmission cooperation of the synchronous belt 18, the screw 13 can be driven to rotate clockwise or counterclockwise.

[0033] Specifically, sliders 5 are fixedly connected to both sides of the bottom of the slide 4, and guide rails 3 that slide with the sliders 5 are fixedly connected to both sides of the top of the support frame 1. Through the cooperation between the sliders 5 and the guide rails 3, the slide 4 can be easily moved above the support frame 1.

[0034] Specifically, a brake device 21 is installed at the bottom of the slide 4, and the brake device 21 is mounted on top of the guide rail 3. By setting the friction between the brake device 21 and the guide rail 3, the slide 4 can be braked to increase some friction and avoid it from moving too fast.

[0035] Specifically, the outer cover of the retaining ring 2 is provided with a shell 19 that can be detached from the slide 4. Furthermore, the shell 19 is locked on the slide 4 by bolts. By providing the shell 19, the retaining ring 2 is conveniently protected and the retaining ring 2 is prevented from being rubbed by surrounding objects during rotation, thereby preventing its rotation from being hindered.
