Technical Field
[0001] This utility model relates to the field of round tube processing technology, specifically a high-precision round tube end face cutting device. Background Art
[0002] Tube end face cutting is a common machining process, mainly used to remove excess material from the ends of round tubes to achieve the required dimensional accuracy and flatness. This machining method is widely used in manufacturing, especially in industries such as machinery, automobiles, and aerospace.
[0003] When cutting the cross-section of a round tube, one end needs to be clamped and fixed, and then the tube is cut by rotation. However, when machining a round tube, both ends usually need to be fixed for cutting, so that corresponding holes and flatness are cut at both ends. In the existing technology, most of the time, one end is fixed, and after the processing of one end is completed, the tube is transferred for further processing. This processing method wastes a lot of manpower and resources, and the processing positions of the two ends are easily different during the transfer process. Therefore, we propose a high-precision round tube end face cutting device. Utility Model Content

[0017] 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.
[0018] Please see Figures 1-3This utility model provides a technical solution: a high-precision round tube end face cutting device, including a base plate 1. On one side of the top of the base plate 1, a first end fixing mechanism 3 for fixing one end of the round tube is fixedly installed by two sets of first fixing blocks 2. On the other side of the top of the base plate 1, two sets of electric slide rails 4 are fixedly installed. An electric slider 5 is slidably connected on the electric slide rail 4. A second end fixing mechanism 6 for fixing the other end of the round tube is fixedly installed on the top of the electric slider 5. A round tube support mechanism 8 for supporting round tubes of different sizes is provided between the first end fixing mechanism 3 and the second end fixing mechanism 6. An adjustment mechanism 7 for driving the round tube support mechanism 8 to move is fixedly installed on the base plate 1.
[0019] The first end fixing mechanism 3 can fix one end of the round tube and drive the round tube to rotate. It cooperates with the external cutting structure to complete the end cutting process. After the cutting of one end is completed, the electric slider 5 and the second end fixing mechanism 6 can move along the electric slide rail 4. The second end fixing mechanism 6 can then fix and clamp the other end of the round tube. Then the first end fixing mechanism 3 is released, and the electric slider 5 and the second end fixing mechanism 6 can return along the electric slide rail 4. In this way, the first end fixing mechanism 3 and the second end fixing mechanism 6 can fix both ends of the round tube respectively, ensuring that the processing positions of the two ends of the round tube correspond during the processing. When processing one end of the round tube, the round tube support mechanism 8 can support and limit the movement to prevent displacement during the cutting of the round tube end. The set adjustment mechanism 7 can drive the round tube support mechanism 8 to move left and right, so as to support and limit the round tube of different lengths. The set round tube support mechanism 8 can support and limit the round tube of different sizes, making it more adaptable.
[0020] Please see Figure 1 and Figure 2 The first end fixing mechanism 3 and the second end fixing mechanism 6 have the same structure and both include a motor frame 9, a support frame 10, a three-jaw chuck 11 and a fixing claw 12. A support frame 10 is provided on one side of the motor frame 9. A motor is provided inside the motor frame 9. The output end of the motor is fixedly connected to the three-jaw chuck 11. A support frame 10 is fixedly installed on one side of the motor frame 9 and outside the three-jaw chuck 11. Three sets of fixing claws 12 are provided on the three-jaw chuck 11. A clamping seat 13 is fixedly installed on the fixing claw 12.
[0021] When the first end fixing mechanism 3 and the second end fixing mechanism 6 fix the end of the round tube, the round tube support mechanism 8 supports the outer wall of the round tube. Then, one end of the round tube corresponds to the three-jaw chuck 11. Then, the three-jaw chuck 11 drives multiple sets of fixing jaws 12 and clamping seats 13 to move relative to each other, so that the clamping and fixing of one end of the round tube can be completed. Then, the motor set inside the motor frame 9 can drive the three-jaw chuck 11 to rotate, so that it can cooperate with the external cutting mechanism to complete the cutting of the cross section of the round tube.
[0022] Please see Figure 1 and Figure 2 The adjustment mechanism 7 includes a first mounting plate 14, a threaded rod 15, a first drive motor 16, and a first threaded sleeve 17. Two sets of first mounting plates 14 are fixedly mounted on the top of the base plate 1. A threaded rod 15 is rotatably connected between the two sets of first mounting plates 14. A first drive motor 16 is fixedly mounted on one side of the first mounting plate 14. The output end of the first drive motor 16 is fixedly connected to the threaded rod 15. The threaded rod 15 is externally threaded to the first threaded sleeve 17. Two sets of slide rails 18 are fixedly mounted on the top of the base plate 1. A slider 19 is slidably connected on the slide rails 18. A second mounting plate 20 is fixedly mounted on the top of the slider 19. The top of the first threaded sleeve 17 is fixedly connected to the second mounting plate 20.
[0023] When the position of the round tube support mechanism 8 needs to be adjusted, the first drive motor 16 operates, and the first drive motor 16 drives the threaded rod 15 to rotate. Then the rotating threaded rod 15 can drive the first threaded sleeve 17 and the second mounting plate 20 to move left and right. When the second mounting plate 20 moves, it can be limited by the slider 19 and the slide rail 18. In this way, the left and right position of the round tube support mechanism 8 can be adjusted.
[0024] Please see Figure 1 and Figure 3 The circular tube support mechanism 8 includes a first support rod 30, a second support rod 31, a rotating shaft 32, and a support roller 33. The first support rod 30 and the second support rod 31 are rotatably connected by the rotating shaft 32, and the support roller 33 is rotatably connected to the first support rod 30 and the second support rod 31.
[0025] The first support rod 30 and the second support rod 31 can support and limit the two sets of support rollers 33. When the round tube rotates, the support rollers 33 can be used to support and limit it, thereby preventing the first end fixing mechanism 3 and the second end fixing mechanism 6 from tilting due to the weight of the round tube when they clamp it.
[0026] Please see Figure 1 , Figure 2 and Figure 3The circular tube support mechanism 8 further includes an adjusting frame 21, a dual-axis screw 22, a limiting rod 23, a second drive motor 24, a second threaded sleeve 25, a connecting seat 27, and a third mounting plate 28. The adjusting frame 21 is fixedly mounted on the top of the second mounting plate 20. The dual-axis screw 22 is rotatably connected inside the adjusting frame 21. The second drive motor 24 is fixedly mounted on one side of the adjusting frame 21. The output end of the second drive motor 24 is fixedly connected to the dual-axis screw 22. Two sets of limiting rods 23 are fixedly mounted inside the adjusting frame 21. Two sets of second threaded sleeves 25 are threadedly connected to the outside of the dual-axis screw 22. Two sets of limiting sleeves 26 are slidably connected to the limiting rods 23. The connecting seat 27 is fixedly connected to the outside of the second threaded sleeves 25 and the limiting sleeves 26. The third mounting plate 28 is fixedly mounted on the top of the connecting seat 27. The first support rod 30 and the second support rod 31 are hinged to the two sets of third mounting plates 28 through hinge seats 29.
[0027] When the required diameter of the round tube is different, the second drive motor 24 operates, driving the dual-axis screw 22 to rotate. The dual-axis screw 22 can then use the second threaded sleeve 25 to move the two sets of connecting seats 27 and the third mounting plate 28 relative to each other. When the third mounting plate 28 moves, the first support rod 30 and the second support rod 31 can be limited by the hinge seat 29 and the rotating shaft 32. This allows the position of the two sets of support rollers 33 to be adjusted, thus supporting and limiting the diameter of round tubes of different sizes. When the connecting seat 27 moves, it can be limited by the limiting rod 23 and the limiting sleeve 26, thus preventing the third mounting plate 28 from shifting during movement.
[0028] Please see Figure 1 and Figure 3 Rubber pads are provided on the outside of the support roller 33 and the bottom of the clamping seat 13. The rubber pads on the support roller 33 and the clamping seat 13 can prevent the round tube from being scratched when in contact with it.
[0029] In use, firstly, the first end fixing mechanism 3 can fix one end of the round tube and drive the round tube to rotate, cooperating with the external cutting structure to complete the end cutting process. After the cutting of one end is completed, the electric slider 5 and the second end fixing mechanism 6 can move along the electric slide rail 4, and the second end fixing mechanism 6 can be used to fix and clamp the other end of the round tube. Then, the first end fixing mechanism 3 is released, and the electric slider 5 and the second end fixing mechanism 6 can return along the electric slide rail 4. In this way, the first end fixing mechanism 3 and the second end fixing mechanism 6 can be used to fix both ends of the round tube, thus ensuring that the processing positions of the two ends of the round tube correspond during the processing. When processing one end of the round tube... The round tube support mechanism 8 can be used for support and limitation to prevent displacement during the cutting of the round tube end. The adjustment mechanism 7 can drive the round tube support mechanism 8 to move left and right, thus supporting and limiting round tubes of different lengths. Furthermore, the round tube support mechanism 8 can support and limit round tubes of different sizes, offering wider adaptability. When the first end fixing mechanism 3 and the second end fixing mechanism 6 fix the round tube end, the round tube support mechanism 8 supports the outer wall of the round tube. Then, one end of the round tube corresponds to the three-jaw chuck 11. Subsequently, the three-jaw chuck 11 drives multiple sets of fixing jaws 12 and clamping seats 13 to move relative to each other, thus completing the clamping and fixing of one end of the round tube. Then, the motor inside the motor frame 9 can drive the three-jaw chuck 11 to rotate, thus... The circular tube support mechanism 8 is cut in conjunction with an external cutting mechanism. When the position of the circular tube support mechanism 8 needs to be adjusted, the first drive motor 16 operates, driving the threaded rod 15 to rotate. The rotating threaded rod 15 then drives the first threaded sleeve 17 and the second mounting plate 20 to move left and right. When the second mounting plate 20 moves, it can be limited by the slider 19 and the slide rail 18. This allows for adjustment of the left and right position of the circular tube support mechanism 8. The first support rod 30 and the second support rod 31 can support and limit the two sets of support rollers 33. When the circular tube rotates, the support rollers 33 can support and limit it, thereby preventing the first end fixing mechanism 3 and the second end fixing mechanism 6 from being fixed. When clamping the round tube, the tube tilts due to its own weight. When the round tubes to be processed are of different sizes, the second drive motor 24 operates, driving the dual-axis screw 22 to rotate. The dual-axis screw 22 can then use the second threaded sleeve 25 to move the two sets of connecting seats 27 and the third mounting plate 28 relative to each other. When the third mounting plate 28 moves, the first support rod 30 and the second support rod 31 can be limited by the hinge seat 29 and the rotating shaft 32. This allows the position of the two sets of support rollers 33 to be adjusted, thus supporting and limiting round tubes of different sizes. When the connecting seat 27 moves, it can be limited by the limiting rod 23 and the limiting sleeve 26, thus preventing the third mounting plate 28 from shifting during movement.
