Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0027] Example 1

The first support component 23 is used to support the first elastic element 2, and the second support component 33 is used to support the second elastic element 3. A driving component 6 is used to drive the first elastic element 2 to compress and deform. When the first elastic element 2 is compressed and deformed, it abuts against the inner wall of the pipe. The cutting device also includes... The device includes a first lifting assembly 4 and a second lifting assembly 5. A disc cutter 51 is connected to the second lifting assembly 5, and the cutting disc of the disc cutter 51 corresponds to the area between the first elastic element 2 and the second elastic element 3. A clamping assembly 41 is connected to the first lifting assembly 4. The first lifting assembly 4 is used to drive the clamping assembly 41 to move up and down and to abut against the outer wall of the pipe. The clamping assembly 41 is connected to a transmission assembly 7, which is connected to the second elastic element 3. During the up and down movement of the clamping assembly 41 driven by the first lifting assembly 4, the transmission assembly 7 can drive the second elastic element 3 to deform. When the second elastic element 3 is compressed and deformed, it abuts against the inner wall of the pipe.

[0029] The cutting equipment also includes a linear motion mechanism 10, a first support limiting seat 8, and a second support limiting seat 9. The linear motion mechanism 10 drives the second support component 33 to move horizontally in a linear motion, thereby driving the second elastic element 3 to move horizontally in a linear motion. Both the first support limiting seat 8 and the second support limiting seat 9 are used to support the pipe. The first support limiting seat 8 is located below the first elastic element 2, and the first support limiting seat 8 is provided with a groove structure adapted to the pipe. The second support limiting seat 9 is located below the second elastic element 3, and the position of the second support limiting seat 9 corresponds to that of the clamping component 41. The second support limiting seat 9 is also provided with a groove structure adapted to the pipe. The linear motion mechanism 10, the first support limiting seat 8, the second support limiting seat 9, the first support component 23, the second support component 33, the first lifting component 4, and the second lifting component 5 can all be installed on the same platform or frame (not shown in the figure).

[0030] A limiting ring 11 is embedded in the support base 1, and one end of the tube is used to abut against one end face of the limiting ring 11.

[0031] The first elastic element 2 includes a horizontally arranged first spring 21. A first elastic spiral sleeve 22 is fixedly sleeved on a section of the first spring 21 adjacent to the second elastic element 3. The first elastic spiral sleeve 22 is made of rubber or silicone. To facilitate the cooperation between the first elastic spiral sleeve 22 and the first spring 21, the first elastic spiral sleeve 22 can be set into two or more parts, and each part can be spliced ​​by bonding or other methods.

[0032] The first support assembly 23 includes a first connecting seat 232, and the first spring 21 and the first elastic spiral sleeve 22 are fixedly connected to the first connecting seat 232 at one end adjacent to the second elastic element 3; the first support assembly 23 also includes a first support column 231, one end of the first support column 231 is fixedly connected to the first connecting seat 232, and the other end of the first support column 231 is fixedly mounted on the support seat 1; the first support column 231 is horizontally arranged and passes through the limiting ring 11; in addition, the central axis of the first spring 21 is collinear with the axis of the first support column 231.

[0033] The drive assembly 6 includes a first guide cylinder 61, one end of which is fixed inside the limiting ring 11, and a portion of which is located inside the first spring 21. A first sliding sleeve 631 is fitted to the outside of the first guide cylinder 61, and the first sliding sleeve 631 can move along the first guide cylinder 61. A first fixing ring 63 is fixedly fitted to the outside of the first sliding sleeve 631, and the end of the first spring 21 away from the first connecting seat 232 is fixedly connected to the first fixing ring 63. The first guide cylinder 61 cooperates with a first movable sleeve 62, a portion of which is fitted inside the first guide cylinder 61, and one end of the first movable sleeve 62 extends out of the first guide cylinder 61. A support ring 66 is fixedly fitted to the end of the first movable sleeve 62 located outside the first guide cylinder 61. Two first pulleys 64 are provided at the end of the first guide cylinder 61 located inside the first spring 21, and the two first pulleys 64 are symmetrically arranged.

[0034] An iron ring 67 is provided on the support ring 66, and an annular electromagnet 68 is provided on the support base 1. The annular electromagnet 68 is positioned corresponding to the iron ring 67. When the annular electromagnet 68 is energized, it is used to attract the iron ring 67. In addition, the first support column 231 passes through the first movable sleeve 62 and the iron ring 67. The inner diameter of the first movable sleeve 62 is larger than the outer diameter of the first support column 231, and the first support column 231, the first movable sleeve 62 and the first guide cylinder 61 are coaxial. Therefore, the first support column 231 does not contact the first movable sleeve 62.

[0035] The drive assembly 6 also includes two first connecting ropes 65. One end of each first connecting rope 65 is fixed to a first fixing ring 63, and the other end is fixed to the end of the first movable sleeve 62 away from the support ring 66. The two first connecting ropes 65 pass over two first pulleys 64 respectively. A blocking plate 69 is provided on the support base 1 to block the support ring 66. When the support ring 66 contacts the blocking plate 69 and the first spring 21 is in the normal state, the two first connecting ropes 65 are just in a straight state or are basically in a straight state. When the annular electromagnet 68 is energized, the iron ring 67 is attracted, thereby causing the first movable sleeve 62 to move horizontally in a straight line. Under the action of the first connecting ropes 65, the first fixing ring 63 can be moved along the first guide cylinder 61 towards the first connecting base 232, thereby causing the first spring 21 to be compressed, and further causing the first elastic spiral sleeve 22 to be compressed and deformed.

[0036] The second elastic element 3 includes a horizontally arranged second spring 31. A second elastic spiral sleeve 32 is fixedly sleeved on a section of the second spring 31 adjacent to the first elastic element 2. The second elastic spiral sleeve 32 is made of rubber or silicone. Similarly, in order to facilitate the cooperation between the second elastic spiral sleeve 32 and the second spring 31, the second elastic spiral sleeve 32 can be set into two or more parts, and each part can be spliced ​​by bonding or other methods.

[0037] The second support assembly 33 includes a first connecting seat 232, and the second spring 31 and the second elastic spiral sleeve 32 are both fixedly connected to the second connecting seat 332 at one end adjacent to the first elastic element 2. The second support assembly 33 also includes a movable frame 333 and a second support column 331. The second support column 331 is horizontally arranged, with one end of the second support column 331 fixedly connected to the second connecting seat 332 and the other end of the second support column 331 fixedly mounted on the movable frame 333. The second support column 331 is coaxial with the first support column 231. The movable frame 333 is used to connect to the linear motion mechanism 10, and the linear motion mechanism 10 is used to drive the movable frame 333 to move linearly along the axis of the second support column 331. At the same time, the central axis of the second spring 31 is coaxial with the axis of the second support column 331.

[0038] The clamping assembly 41 includes a fixed base 411, which is connected to a second lifting assembly 5. The second lifting assembly 5 is used to drive the fixed base 411 to move up and down. An arc-shaped clamping plate 412 is fixedly provided at the bottom of the fixed base 411. The arc-shaped clamping plate 412 is adapted to the outer wall of the pipe to be cut. That is, by driving the arc-shaped clamping plate 412 down through the second lifting assembly 5, the arc-shaped clamping plate 412 can be driven to abut against the outer wall of the pipe. Under the action of the second support limiting seat 9, the pipe can be fixed.

[0039] The transmission assembly 7 includes a horizontally arranged second guide cylinder 71, a portion of which is located inside the second spring 31; the second guide cylinder 71 penetrates the movable frame 333 and is fixedly connected to the movable frame 333; a second sliding sleeve 731 is fitted to the outside of the second guide cylinder 71, and the second sliding sleeve 731 can move along the second guide cylinder 71; a second fixing ring 73 is fixedly sleeved on the outside of the second sliding sleeve 731, and the end of the second spring 31 away from the second connecting seat 332 is fixedly connected to the second fixing ring 73; the second guide cylinder 71 cooperates with the second movable sleeve 72, and the second movable sleeve... A portion of the cylinder 72 is fitted inside the second guide cylinder 71. One end of the second movable sleeve 72 extends out of the second guide cylinder 71, and a fixing block 76 is fixedly fitted onto the end of the second movable sleeve 72 that extends out of the second guide cylinder 71. Two second pulleys 74 are provided at the end of the second guide cylinder 71 located inside the second spring 31, and the two second pulleys 74 are symmetrically arranged. Two second connecting ropes 75 are fixedly connected to the end of the second movable sleeve 72 away from the fixing block 76. The other end of the second connecting ropes 75 is fixedly connected to the second fixing ring 73, and the two second connecting ropes 75 respectively pass around the two second pulleys 74.

[0040] The second support column 331 passes through the second movable sleeve 72. The inner ring diameter of the second movable sleeve 72 is larger than the outer diameter of the second support column 331, and the second support column 331, the second movable sleeve 72 and the second guide cylinder 71 are coaxial.

[0041] The transmission assembly 7 also includes a third connecting rope 79 and a third pulley 77 and a fourth pulley 78 disposed on the movable frame 333. The fourth pulley 78 is located between the third pulley 77 and the fixed seat 411. One end of the third connecting rope 79 is fixedly connected to the fixed seat 411, and the third connecting rope 79 passes around the third pulley 77 and the fourth pulley 78 in sequence.

[0042] In the initial state, the second spring 31 and the second elastic spiral sleeve 32 are in normal condition, and the second connecting rope 75 and the third connecting rope 79 are in a straight state. The entire second elastic element 3 is at a suitable position from the first elastic element 2 (which can be achieved by the linear motion mechanism 10 driving the moving frame 333 to move), which can easily bring one end of the entire pipe against the limiting ring 11, and make the pipe sleeved outside the first spring 21 and the first elastic spiral sleeve 22.

[0043] When placing the pipe, one end of the pipe abuts against the limiting ring 11, causing the pipe to be sleeved outside the first spring 21 and the first elastic spiral sleeve 22. Simultaneously, the pipe is supported by the first supporting limiting seat 8 and the second supporting limiting seat 9. When the pipe is fitted onto the first supporting limiting seat 8 and the second supporting limiting seat 9, the pipe, the first supporting column 231, and the second supporting column 331 are coaxial. At this time, the outer walls of the first elastic spiral sleeve 22 and the second elastic spiral sleeve 32 are close to the inner wall of the pipe. Then, the linear motion mechanism 10 drives the moving frame 333 to move towards the first elastic element 2 until the second elastic spiral sleeve 32 approaches the first elastic spiral sleeve 22, i.e., as shown. Figure 2 In the state shown, the adjacent ends of the first elastic spiral sleeve 22 and the second elastic spiral sleeve 32 are respectively close to the part of the pipe to be cut. At this time, the cutting disc of the disc cutter 51 corresponds to the area between the first elastic spiral sleeve 22 and the second elastic spiral sleeve 32. Similarly, the cutting disc of the cutter corresponds to the area between the first connecting seat 232 and the second connecting seat 332. Then, with the help of manual temporary pressing to fix the pipe, the fixing seat 411 and the arc-shaped clamping plate 412 are driven to move downward through the first lifting component 4. The arc-shaped clamping plate 412 abuts against and squeezes the outer wall of the pipe, thereby fixing the pipe.

[0044] When the arc-shaped clamping plate 412 descends to contact the pipe, the fixing seat 411 pulls the third connecting rope 79, causing the fixing block 76 to move away from the second connecting seat 332. This further drives the second moving sleeve 72 to move away from the second connecting seat 332. Under the action of the second connecting rope 75 and the second sliding sleeve 731, the second fixing ring 73 can be driven to move closer to the second connecting seat 332, causing the second spring 31 to compress and deform, which in turn causes the second elastic spiral sleeve 32 to compress and deform. That is, during the process of the arc-shaped clamping plate 412 descending to contact the pipe, the second elastic spiral sleeve 32 is compressed and deformed, and the second elastic spiral sleeve 32 abuts and squeezes the inner wall of the pipe, which can improve the fixing effect on the pipe.

[0045] After the pipe is pressed against the arc-shaped clamping plate 412, the annular electromagnet 68 is energized, attracting the iron ring 67, which causes the first moving sleeve 62 to move horizontally in a straight line. Under the action of the first connecting rope 65, the first fixing ring 63 is moved along the first guide cylinder 61 towards the first connecting seat 232, thereby causing the first spring 21 to compress, which in turn causes the first elastic spiral sleeve 22 to compress and deform. The first elastic spiral sleeve 22 also presses against the inner wall of the pipe, which can improve the fixing effect on the pipe. Finally, the second lifting component 5 drives the disc cutting machine 51 to descend, which can completely cut the pipe.

[0046] During the pipe cutting process, the inner wall of the pipe is squeezed by the first elastic spiral sleeve 22 and the second elastic spiral sleeve 32, which helps to reduce the concave deformation of the pipe cutting position and improves the cutting quality.

[0047] After cutting, the second lifting assembly 5 drives the disc cutter 51 to reset, while the first lifting assembly 4 drives the fixed seat 411 to reset downwards, facilitating the reset of the fixed block 76, the second spring 31, the second elastic spiral sleeve 32, etc. At the same time, the annular electromagnet 68 is de-energized, facilitating the reset of the iron ring 67, the first spring 21, the first elastic spiral sleeve 22, etc. The second spring 31, the second elastic spiral sleeve 32, and the second connecting seat 332 can be completely detached from the cut pipe by manually pressing the part of the pipe directly above the second support limit seat 9 and moving the moving frame 333 through the linear motion mechanism 10. Finally, the section of pipe sleeved outside the first elastic element 2 is taken out, which is the required pipe.
