Description
Technical Field
[0001] This application relates to the technical field of pipe cutters, and specifically to a pipe cutter. Background Art
[0002] With the acceleration of the urban modernization process, various pipelines such as power, telecommunications, gas, water supply and drainage, etc. are overlapped. When some pipelines need to be repaired or updated, a pipe cutter is required to cut them.
[0003] There is generally a limitation in existing pipe cutters, that is, they can usually only effectively cut pipes with a specific radius. When facing pipes with different radii, in order to ensure the accuracy and efficiency of cutting, it is often necessary to replace them with a special pipe cutter suitable for the radius of the pipe, and frequent replacement will increase the complexity and time cost of the work. Content of the Utility Model
[0004] In view of the deficiencies of the prior art, this application provides a pipe cutter, which has the advantages of a higher applicable range, and solves the limitation that generally exists in existing pipe cutters, that is, they can usually only effectively cut pipes with a specific radius. When facing pipes with different radii, in order to ensure the accuracy and efficiency of cutting, it is often necessary to replace them with a special pipe cutter suitable for the radius of the pipe, and frequent replacement will increase the complexity and time cost of the work.
[0005] To achieve the above object, this application provides the following technical solution: A pipe cutter includes a mounting block, on the surface of the mounting block are fixedly connected two handles distributed in a mirror image, on the surface of the mounting block are fixedly connected two extension blocks distributed in a mirror image, inside both of the two extension blocks are fixedly connected electric cylinders, and the telescopic ends of the electric cylinders penetrate through the extension blocks and are fixedly connected with fixed blocks.
[0006] An installation groove is opened inside the fixed block, a bidirectional lead screw is rotatably connected inside the installation groove, both ends of the bidirectional lead screw are thread sleeved with sliding blocks distributed in a mirror image, the surfaces of both of the two sliding blocks are slidably connected with the inner wall of the installation groove, one end of the fixed block is fixedly connected with a first motor, the output end of the first motor extends into the installation groove and is fixedly connected with one end of the bidirectional lead screw, on the surface of one end of both of the two sliding blocks are fixedly connected two mounting columns distributed in a mirror image, and a pulley is rotatably connected inside the mounting column.
[0007] With the above solution, when in use, two electric cylinders are started. The electric cylinders will drive two fixed blocks to move towards each other or in opposite directions. When the two fixed blocks move, they will drive the pulleys to move, thereby changing the gap between the two groups of pulleys. At the same time, the first motor is started. The first motor drives the bidirectional lead screw to rotate, thereby driving the two sliding blocks to move towards each other or in opposite directions, and further changing the distance between the pulleys installed on the two sliding blocks, achieving the position adjustment of the pulleys in two orthogonal directions, enabling it to easily handle pipes of various radii, without the need to frequently replace tools or perform complex setting adjustments, which can reduce the complexity of the working process and at the same time reduce the working time cost.
[0008] Furthermore, two guide columns distributed in a mirror image are fixedly connected to the surface of the fixed block. One end of each of the two guide columns penetrates through the extension block and is slidably connected to the extension block. A stop block is fixedly connected to one end of each of the two guide columns.
[0009] With the above solution, the guide columns can enable the fixed block to slide smoothly and precisely along the trajectory of the guide columns when being driven by the electric cylinder to move, while avoiding deviation or shaking.
[0010] Furthermore, a sliding groove is opened in the middle of the mounting block. A threaded rod is rotatably connected inside the sliding groove. One end of the mounting block is fixedly connected with a second motor. The output end of the second motor extends into the sliding groove and is fixedly connected with one end of the threaded rod.
[0011] With the above solution, when the second motor is started, its power will be directly transmitted to the threaded rod, driving it to rotate.
[0012] Furthermore, a sliding table is threadedly sleeved on the outside of the threaded rod. The surface of the sliding table is slidably connected to the inner wall of the sliding groove. A cutting cover is fixedly connected to the upper end of the sliding table.
[0013] With the above solution, when the threaded rod rotates, the sliding table can slide along the axial direction of the threaded rod. By controlling the rotation direction and speed of the threaded rod, the position and cutting depth of the cutting cover can be precisely adjusted, so as to meet the requirements of different pipe cutting tasks.
[0014] Furthermore, a third motor is fixedly connected to the surface of the cutting cover. The output end of the third motor extends into the inner wall of the cutting cover and is fixedly connected with a cutting blade.
[0015] With the above solution, when the third motor is started, its power will be directly transmitted to the cutting blade, driving it to perform a rotational motion. The rotating cutting blade contacts the surface of the pipe and generates a shearing force, thereby cutting off the pipe material. The cutting cover plays a certain protective role and can enclose the cutting blade and the pipe cutting area, preventing the flying objects or debris generated during the cutting process from polluting or harming the surrounding environment.
[0016] Furthermore, two mirror-image distributed slide rails are fixedly connected to the surface of the mounting block, and sliders are slidably sleeved on the surfaces of both slide rails, and the surfaces of both sliders are fixedly connected to the surface of the cutting cover.
[0017] Through the above solution, due to the sliding connection between the slide rail and the slider having a small frictional resistance and high precision, the smoothness and accuracy of the cutting process can be ensured.
[0018] Compared with the prior art, the technical solution of the present application has the following beneficial effects:
[0019] When using this pipe cutter, start two electric cylinders. The electric cylinders will drive two fixed blocks to move towards or away from each other. When the two fixed blocks move, they will drive the pulleys to move, thereby changing the gap between the two groups of pulleys. At the same time, start the first motor. The first motor drives the bidirectional lead screw to rotate, thereby driving two sliding blocks to move towards or away from each other, and further changing the distance between the pulleys installed on the two sliding blocks, realizing the position adjustment of the pulleys in two orthogonal directions, enabling it to easily handle pipes of various radii, without the need to frequently replace tools or perform complex setting adjustments, which can reduce the complexity of the work process and at the same time reduce the working time cost.

DETAILED DESCRIPTION OF THE EMBODIMENTS
[0026] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in the present application without creative efforts belong to the scope of protection of the present application.
[0027] Please refer to Figure 1 , Figure 3 and Figure 4 , a pipe cutter in this embodiment includes a mounting block 1. Two mirror-image distributed handles 22 are fixedly connected to the surface of the mounting block 1. Two mirror-image distributed extension blocks 2 are fixedly connected to the surface of the mounting block 1. Electric cylinders 3 are fixedly connected inside both extension blocks 2. The telescopic ends of the electric cylinders 3 penetrate through the extension blocks 2 and are fixedly connected to a fixed block 4. An installation groove 7 is opened inside the fixed block 4. A bidirectional lead screw 8 is rotatably connected inside the installation groove 7. Mirror-image distributed sliding blocks 10 are threadedly sleeved at both ends of the bidirectional lead screw 8. The surfaces of both sliding blocks 10 are slidably connected to the inner wall of the installation groove 7. One end of the fixed block 4 is fixedly connected to a first motor 9. The output end of the first motor 9 extends into the installation groove 7 and is fixedly connected to one end of the bidirectional lead screw 8. Two mirror-image distributed mounting columns 11 are fixedly connected to the surface of each of the two sliding blocks 10. A pulley 12 is rotatably connected inside the mounting column 11.
[0028] Please refer to Figure 3 , two mirror-image distributed guide columns 5 are fixedly connected to the surface of the fixed block 4. One end of each of the two guide columns 5 penetrates through the extension block 2 and is slidably connected to the extension block 2. A stop block 6 is fixedly connected to one end of each of the two guide columns 5. The guide columns 5 can enable the fixed block 4 to slide smoothly and precisely along the trajectory of the guide columns 5 when being driven by the electric cylinder, while avoiding deviation or shaking.
[0029] Please refer to Figure 1 , a sliding groove 13 is opened in the middle of the mounting block 1. A threaded rod 14 is rotatably connected inside the sliding groove 13. One end of the mounting block 1 is fixedly connected to a second motor 16. The output end of the second motor 16 extends into the sliding groove 13 and is fixedly connected to one end of the threaded rod 14. When the second motor 16 is started, its power will be directly transmitted to the threaded rod 14 to drive it to rotate. A sliding table 15 is threadedly sleeved outside the threaded rod 14. The surface of the sliding table 15 is slidably connected to the inner wall of the sliding groove 13. A cutting cover 17 is fixedly connected to the upper end of the sliding table 15. When the threaded rod 14 rotates, the sliding table 15 can slide along the axial direction of the threaded rod 14. By controlling the rotation direction and speed of the threaded rod 14, the position and cutting depth of the cutting cover 17 can be precisely adjusted to meet the requirements of different pipe cutting tasks.
[0030] Please refer to Figure 2, a third motor 18 is fixedly connected to the surface of the cutting cover 17. The output end of the third motor 18 extends into the inner wall of the cutting cover 17 and is fixedly connected to a cutting blade 19. When the third motor 18 is started, its power will be directly transmitted to the cutting blade 19, driving it to perform a rotational motion. The rotating cutting blade 19 contacts the surface of the pipe and generates a shearing force, thereby cutting off the pipe material. The cutting cover 17 plays a certain protective role, capable of enclosing the cutting blade 19 and the pipe cutting area, preventing the flying objects or debris generated during the cutting process from polluting or damaging the surrounding environment. Two mirror-image distributed slide rails 20 are fixedly connected to the surface of the mounting block 1. Slide blocks 21 are slidably sleeved on the surfaces of both slide rails 20. The surfaces of both slide blocks 21 are fixedly connected to the surface of the cutting cover 17. Since the sliding connection between the slide rail 20 and the slide block 21 has a small frictional resistance and high precision, the smoothness and accuracy of the cutting process can be ensured.
[0031] The working principle of the above embodiment is as follows:
[0032] First, start the two electric cylinders 3. The telescopic ends of the electric cylinders 3 will extend or retract according to preset or external control signals, thereby driving the fixed blocks 4 to move along the trajectory of the guide posts 5. Since the two fixed blocks 4 are mirror-image distributed, they will move towards or away from each other, thereby changing the overall gap between the two groups of pulleys 12. At the same time, start the first motor 9. The first motor 9 drives the bidirectional lead screw 8 to rotate. Since the thread directions at both ends of the bidirectional lead screw 8 are opposite, the two sliding blocks 10 will move towards or away from each other along the axial direction of the bidirectional lead screw 8, thereby changing the distance between the pulleys 12 mounted on the two sliding blocks 10. In this way, the position adjustment of the pulleys in two orthogonal directions is achieved to adapt to pipes of different radii until multiple pulleys 12 all contact the surface of the pipe, and then start the third motor 18. The third motor 18 drives the cutting blade 19 to rotate at a high speed. Start the second motor 16. The second motor 16 drives the threaded rod 14 to rotate. Due to the threaded connection between the threaded rod 14 and the slide table 15, the slide table 15 will slide along the axial direction of the threaded rod 14 to make the cutting blade 19 contact the pipe. The rotating cutting blade 19 contacts the surface of the pipe and generates a shearing force. Then, hold the handle 22 and rotate the entire device to cut off the pipe material.
