Description

Technical Field

[0001] The present invention relates to a processing device for water supply and drainage pipes, and in particular to a turning machine tool. Background Art

[0002] Mesh bag pipes are widely used in the fields of water supply and drainage pipes, etc. for transporting various fluid media. After long-term use, the inner wall of the mesh bag pipe crystallizes severely. Due to the long length of the mesh bag pipe, it is difficult for manual labor to clean the crystallization layer on its inner wall. If the current turning equipment is used to clean the inner wall of the mesh bag pipe, since the turning tool needs to move a long distance along the axial direction of the mesh bag pipe, and the structure for driving the turning tool cannot provide support inside the mesh bag pipe, it is difficult to ensure the coaxiality of the turning tool moving inside the mesh bag pipe, resulting in poor precision during the cleaning of the crystallization layer on the inner wall of the mesh bag pipe by the turning tool, and it is easy to damage the mesh bag pipe. Therefore, there is an urgent need for a machine tool suitable for turning the inner walls of pipes such as mesh bag pipes. Summary of the Invention

[0003] The purpose of the present invention is to provide a turning machine tool to solve one or more technical problems existing in the prior art, and at least provide a beneficial option or create conditions.

[0004] The solution of the present invention to solve its technical problems is as follows:

[0005] A turning machine tool includes: a rotating device having a transmission sleeve that can rotate along a horizontal axis; a pipe clamping device arranged outside the transmission sleeve, and the pipe clamping device forms an openable and closable pipe clamping area at one end of the transmission sleeve; a processing device including a linear driver, a feed regulator, an aligner, and a tool. The linear driver has a movable seat that can move closer to or away from the pipe clamping area. The feed regulator is arranged on the movable seat, and the feed regulator has an adjusting seat that can move radially along the transmission sleeve. The aligner and the tool are connected to the adjusting seat, and the aligner is used to detect the offset value between the tool and the axis of the transmission sleeve. The adjusting seat is configured to perform radial movement according to the offset value.

[0006] The technical solution has at least the following beneficial effects: Open the pipe clamping area formed within the pipe clamping device, and insert the pipe body to be turned into the pipe clamping area. During operation, the transmission sleeve within the rotating device rotates, driving the pipe clamping device and the pipe body to rotate together. The linear drive within the processing device drives the movable seat into the pipe body, and the tool on the adjustment seat is used to turn and clean the inner wall of the pipe body. When the linear drive drives the movable seat to move in the direction close to or away from the pipe clamping area, that is, drives the movable seat to move axially along the pipe body within the pipe body, the aligner on the adjustment seat can detect the offset value between the tool and the axis of the transmission sleeve. When the tool moves axially along the pipe body and is offset from the axis of the transmission sleeve, the adjustment seat can move radially along the pipe body according to the offset value, thereby compensating for the offset error caused by the bending deformation of the linear drive due to its excessive length during movement, effectively ensuring the coaxiality between the tool and the pipe body when the tool moves within the pipe body. In this way, by adjusting the displacement of the tool feeding towards the inner wall of the pipe in real time, the accuracy of the processing of the inner wall of the pipe can be ensured, and the automatic cleaning and processing of the inner wall of the pipe can be realized, completing the precision turning of the pipe body, especially suitable for pipe bodies such as long mesh bags.

[0007] As a further improvement of the above technical solution, the linear drive includes a mounting seat, a first motor, an outer sleeve pipe, and a screw rod. The first motor and the outer sleeve pipe are respectively connected to the mounting seat. The screw rod is rotatably connected to the mounting seat. The screw rod is located within the outer sleeve pipe. The first motor is in transmission connection with the screw rod. The movable seat is in threaded connection with the screw rod. The movable seat is slidably connected within the outer sleeve pipe. An avoidance slot hole is axially provided on the outer side of the outer sleeve pipe. The adjustment seat extends out of the outer sleeve pipe through the avoidance slot hole. The aligner and the tool are respectively connected to the position where the adjustment seat extends out of the outer sleeve pipe. During use, the pipe body to be turned and cleaned can be sleeved outside the outer sleeve pipe. The outer sleeve pipe can surround and protect the screw rod, reducing the exposure of the structure. It is only necessary to connect the aligner and the tool to the position where the adjustment seat extends out of the outer sleeve pipe, which can better protect the transmission structure. Both the outer sleeve pipe and the screw rod extend within the pipe body, providing support for the axial movement of the movable seat within the pipe body. When it is necessary to control the movement of the tool, the first motor operates to drive the screw rod to rotate. Since the movable seat is in threaded connection with the screw rod and the movable seat is slidably connected within the outer sleeve pipe, as the screw rod rotates, the movable seat can be driven to slide axially within the outer sleeve pipe. Since the lengths of the outer sleeve pipe and the screw rod are relatively long, it is difficult to ensure the straightness of the outer sleeve pipe and the screw rod. Therefore, the aligner detects the offset value between the tool moving axially along the pipe body and the axis of the transmission sleeve, and in this way, the displacement of the tool feeding towards the inner wall of the pipe is adjusted in real time, compensating for the downward bending deformation of the outer sleeve pipe and the screw rod due to gravity, thereby ensuring the accuracy of the processing of the inner wall of the pipe.

[0008] As a further improvement of the above technical solution, the present invention further includes a first support frame and a second support frame. The first support frame defines a first support area, and the second support frame defines a second support area. Two end portions of the outer sleeve respectively extend into the first support area and the second support area. The first support area defined by the first support frame and the second support area defined by the second support frame are used to respectively support and position the two end portions of the outer sleeve, effectively reducing the situation that the outer sleeve bends downward under pressure at the end position, and improving the stability when the movable seat slides in the outer sleeve.

[0009] As a further improvement of the above technical solution, the present invention further includes a base. The base is located on a side of the first support frame away from the second support frame. The mounting seat is slidably connected to the base, and a translation driver is arranged between the mounting seat and the base. The translation driver can drive the mounting seat to slide in a direction close to or away from the second support frame. When it is necessary to load and unload the pipe body, the translation driver can drive the mounting seat to slide on the base in a direction away from the second support frame. At this time, the outer sleeve and the screw rod can be driven to leave the second support frame, so that a space for directly placing the pipe body can be formed between the first support frame and the second support frame. In this way, the pipe body can be conveniently installed and disassembled at the pipe clamping area, and then the translation driver drives the mounting seat to slide in a direction close to the second support frame, and the outer sleeve and the screw rod are inserted into the pipe body, so that the tool can perform turning and cleaning on the inner wall of the pipe body to be processed.

[0010] As a further improvement of the above technical solution, the alignment device includes a receiving plate and a laser emitter. The receiving plate is arranged at least on one side of the movement path of the movable seat, and the adjustment seat is connected with the laser emitter corresponding to the position of the receiving plate. When the outer sleeve or the screw rod is deformed, when the movable seat moves to the deformed position, it will cause the position where the tool feeds into the pipe body to shift. At this time, the emitter on the adjustment seat shifts the emission point to the receiving plate. According to the position where the receiving plate receives the laser, the offset value between the tool and the axis of the transmission sleeve can be obtained, and the adjustment seat performs radial movement compensation according to this offset value to achieve precise machining of the inner wall of the pipe body.

[0011] As a further improvement of the above technical solution, the feed regulator includes an adjusting lead screw and an adjusting rod. The adjusting lead screw is connected to the movable seat, and the adjusting lead screw is drivingly connected to the adjusting rod. The adjusting lead screw can drive the adjusting rod to move in a direction away from or close to the transmission sleeve. A guiding section is formed on the adjusting rod and extends obliquely in a direction away from the axis of the transmission sleeve. The adjusting seat is slidably connected to the movable seat along the radial direction of the transmission sleeve, and the guiding section is inserted into the adjusting seat. The adjusting lead screw adjusts the position of the adjusting rod along the axial direction of the pipe body, which can reduce the requirement for the radial installation space of the adjusting lead screw and the adjusting rod in the outer sleeve, so that the driving source for driving the adjusting seat can be compactly installed in the outer sleeve. When it is necessary to increase the feed depth of the tool into the pipe body, the adjusting lead screw drives the adjusting rod to approach the adjusting seat. Since the guiding section on the adjusting rod is inclined in a direction away from the axis of the transmission sleeve, the guiding section can guide the adjusting seat, so that the tool on the adjusting seat approaches the inner wall of the pipe body further. When it is necessary to reduce the feed depth of the tool into the pipe body, the adjusting lead screw drives the adjusting rod to move in a direction away from the adjusting seat, and the guiding section also guides the adjusting seat, so that the tool on the adjusting seat moves in a direction away from the inner wall of the pipe body. In this way, the tool can be driven to move and adjust radially.

[0012] As a further improvement of the above technical solution, the rotating device includes a base frame and a second motor. A fixed sleeve is connected to the base frame, the transmission sleeve is rotatably connected in the fixed sleeve, the second motor is connected to the base frame, and the second motor is drivingly connected to the transmission sleeve. The transmission sleeve is rotatably installed in the fixed sleeve, which can improve the installation stability of the transmission sleeve. During operation, the second motor provides a rotational driving force to the transmission sleeve to drive the transmission sleeve to rotate, so as to drive the pipe body to rotate through the pipe clamping device.

[0013] As a further improvement of the above technical solution, the pipe clamping device is a three-jaw chuck. There are three jaws in the three-jaw chuck that can move away from or close to each other. An openable and closable pipe clamping area is formed between the three jaws. When the three jaws move away from each other, the pipe clamping area is opened, and the feeding or discharging of the pipe body can be carried out. When the three jaws move close to each other, the pipe clamping area is closed to realize the clamping of the pipe body.

[0014] As a further improvement of the above technical solution, the present invention further includes a limiting frame. A plurality of limiting wheels are circumferentially arranged around the axis of the transmission sleeve in the limiting frame, and a limiting area is formed by enclosing between the plurality of limiting wheels. The limiting area is opposite to the pipe clamping area. When loading the pipe body, the pipe body can enter the limiting area, and the outer wall of the pipe body is abutted by the plurality of limiting wheels to provide support for the pipe body. In this way, the limiting frame provides support for the outside of the pipe body, which can improve the rotational stability of the pipe body.

[0015] As a further improvement of the above technical solution, a plurality of limiting frames are arranged at intervals along the direction away from the pipe clamping area. The multiple limiting frames can provide support at different positions of the pipe body, effectively preventing the pipe body from bending downward due to excessive length, and further improving the stability of the rotation of the pipe body.

[0026] Referring to Figure 1 , a turning machine tool includes a rotating device 100, a pipe clamping device 200 and a machining device. Among them, the rotating device 100 has a transmission sleeve 110 that can rotate along a horizontal axis; the pipe clamping device 200 is arranged outside the transmission sleeve 110, and the pipe clamping device 200 forms an openable and closable pipe clamping area at one end of the transmission sleeve 110; the machining device includes a linear driver, a feed regulator, an aligner and a tool 320. The linear driver has a movable seat 337 that can move closer to or away from the pipe clamping area. The feed regulator is arranged on the movable seat 337. The feed regulator has an adjusting seat 331 that can move radially along the transmission sleeve 110. The aligner and the tool 320 are connected to the adjusting seat 331. The aligner is used to detect the offset value between the tool 320 and the axis of the transmission sleeve 110. The adjusting seat 331 is configured to perform radial movement according to the offset value. In practical applications, when the tool 320 is normally machining the inner wall of the pipe, the distance between the tool 320 and the axis of the transmission sleeve 110 is the normal feed value. When the offset value is greater than the normal feed value, the adjusting seat 331 moves in a direction away from the axis of the transmission sleeve 110. When the offset value is less than the normal feed value, the adjusting seat 331 moves in a direction close to the axis of the transmission sleeve 110, so as to compensate for the offset amount of the tool 320.

[0027] As can be seen from the above, the clamping area formed inside the pipe clamping device 200 is opened, and the pipe body to be turned is inserted into the clamping area. During operation, the transmission sleeve 110 inside the rotating device 100 rotates, driving the pipe clamping device 200 and the pipe body to rotate together. The linear drive inside the processing device drives the movable seat 337 to move into the pipe body, and the tool 320 on the adjusting seat 331 is used to turn and clean the inner wall of the pipe body. When the linear drive drives the movable seat 337 to move in the direction close to or away from the clamping area, that is, drives the movable seat 337 to move along the axial direction of the pipe body inside the pipe body, the aligner on the adjusting seat 331 can detect the offset value between the tool 320 and the axis of the transmission sleeve 110. When the tool 320 moves along the axial direction of the pipe body and there is an offset from the axis of the transmission sleeve 110, the adjusting seat 331 can move radially along the pipe body according to the offset value, thereby compensating for the offset error caused by the bending deformation of the linear drive due to its excessive length during the movement of the tool 320, effectively ensuring the coaxiality between the tool 320 and the pipe body when the tool 320 moves inside the pipe body. In this way, by adjusting the displacement of the tool 320 feeding into the inner wall of the pipe body in real time, the machining accuracy of the inner wall of the pipe body is guaranteed, and automatic cleaning and machining of the inner wall of the pipe body can be realized, completing the precision turning of the pipe body. It is especially suitable for cleaning the crystal layer formed inside the water supply and drainage pipes such as the mesh bag pipe, and realizing the reuse of the pipe body after turning machining.

[0028] The linear drive is mainly used to drive the tool 320 to reciprocate inside the pipe body, and there are various structural forms. For example, the linear drive can adopt a cylinder, a hydraulic cylinder or an electric guide rail, etc. In this embodiment, as Figures 1 to 3 shown, the linear drive includes a mounting seat 332, a first motor 333, an outer sleeve 334 and a screw 336. The first motor 333 and the outer sleeve 334 are respectively connected to the mounting seat 332. The screw 336 is rotatably connected to the mounting seat 332. The screw 336 is located inside the outer sleeve 334. The first motor 333 is in transmission connection with the screw 336. The output shaft of the first motor 333 can be directly driven and connected to the end of the screw 336 to drive the screw 336 to rotate, or the output shaft of the first motor 333 and the end of the screw 336 are in transmission connection through gear meshing, so as to realize the transmission connection between the two. The movable seat 337 is in threaded connection with the screw 336. The movable seat 337 is slidably connected inside the outer sleeve 334. The outer side of the movable seat 337 and the inner side of the outer sleeve 334 can be slidably matched through a slide rail and a chute. An avoidance slot hole 335 is arranged on the outer side of the outer sleeve 334. The avoidance slot hole 335 extends along the axial direction of the outer sleeve 334. The adjusting seat 331 extends out of the outer sleeve 334 from the avoidance slot hole 335. The aligner and the tool 320 are respectively connected to the position where the adjusting seat 331 extends out of the outer sleeve 334.

[0029] In this linear drive, during use, the pipe body to be turned and cleaned can be sleeved outside the outer sleeve 334. The outer sleeve 334 can surround and protect the screw 336, reducing the exposure of the structure. It is only necessary to connect the aligner and the tool 320 to the position where the adjusting seat 331 extends out of the outer sleeve 334, which can better protect the transmission structure. Both the outer sleeve 334 and the screw 336 extend inside the pipe body, and can provide support for the axial movement of the movable seat 337 inside the pipe body. When it is necessary to control the movement of the tool 320, the first motor 333 operates to drive the screw 336 to rotate. Since the movable seat 337 is threadedly connected to the screw 336 and the movable seat 337 is slidably connected inside the outer sleeve 334, with the rotation of the screw 336, the movable seat 337 can be driven to slide axially inside the outer sleeve 334. Since the lengths of the outer sleeve 334 and the screw 336 are relatively long, it is difficult to ensure the straightness of the outer sleeve 334 and the screw 336. Therefore, the aligner is used to detect the offset value between the axial movement of the tool 320 along the pipe body and the axis of the transmission sleeve 110, and thus the displacement of the tool 320 feeding towards the inner wall of the pipe body is adjusted in real time to compensate for the downward bending deformation of the outer sleeve 334 and the screw 336 due to gravity, thereby ensuring the machining accuracy of the inner wall of the pipe body.

[0030] In the above embodiment, if only one end of the outer sleeve 334 is connected to the mounting seat 332 for support, the support stability of the outer sleeve 334 is relatively poor. Since the pipe body needs to be sleeved outside the outer sleeve 334, it is difficult to add a support structure in the middle position of the outer sleeve 334. Support can be provided at the end position of the outer sleeve 334. Specifically, the present invention further includes a first support frame 410 and a second support frame 420. The first support frame 410 encloses a first support area, and the second support frame 420 encloses a second support area. The two end portions of the outer sleeve 334 respectively extend into the first support area and the second support area. The first support area formed by enclosing the first support frame 410 and the second support area formed by enclosing the second support frame 420 are used to respectively support and position the two end portions of the outer sleeve 334, effectively reducing the situation that the outer sleeve 334 bends downward under pressure at the end position, and improving the stability of the movable seat 337 when sliding inside the outer sleeve 334.

[0031] In practical applications, a sliding sleeve is installed on the first support frame 410, and the first support area is formed by enclosing the sliding sleeve to provide support for the outer sleeve 334. A plurality of support wheels are installed inside the second support frame 420, and the second support area is formed by enclosing between the plurality of support wheels. The plurality of support wheels respectively abut against the outer side position of the end portion of the outer sleeve 334 to provide support and positioning for the outer sleeve 334.

[0032] In order to facilitate the installation of the pipe body outside the outer sleeve 334 and connect it to the pipe clamping area of the pipe clamping device 200, the present invention further includes a base 510. The base 510 is located on the side of the first support frame 410 away from the second support frame 420. The mounting seat 332 is slidably connected to the base 510. A translation drive 520 is provided between the mounting seat 332 and the base 510. The translation drive 520 can drive the mounting seat 332 to slide in a direction close to or away from the second support frame 420. When loading and unloading the pipe body, the translation drive 520 can be used to drive the mounting seat 332 to slide on the base 510 in a direction away from the second support frame 420. At this time, the outer sleeve 334 and the screw 336 can be driven away from the second support frame 420, so that a space for directly placing the pipe body is formed between the first support frame 410 and the second support frame 420. In this way, the pipe body can be conveniently installed and disassembled at the pipe clamping area. Then, the translation drive 520 drives the mounting seat 332 to slide in a direction close to the second support frame 420, and the outer sleeve 334 and the screw 336 are inserted into the pipe body, so that the cutter 320 can perform turning and cleaning on the inner wall of the pipe body to be processed.

[0033] The translation drive 520 is mainly used to provide a driving force for the mounting seat 332 to reciprocate along the axis direction of the transmission sleeve 110. There are various structural forms, such as cylinders, lead screws or hydraulic cylinders. Since the outer sleeve 334 needs to move a long distance to avoid the installed pipe body, in this embodiment, the translation drive 520 adopts a meshing transmission mode of a gear and a rack. Specifically, the translation drive 520 includes a third motor, a first gear and a rack. The third motor is connected to the mounting seat 332. The third motor is drivingly connected to the first gear. The third motor can drive the first gear to rotate self. The rack is connected to the base 510. The rack extends along a direction parallel to the axis of the transmission sleeve 110. The first gear and the rack are meshed with each other. When the mounting seat 332 needs to slide on the base 510, the third motor drives the first gear to rotate forward or backward, so that the mounting seat 332 can slide on the base 510 in a direction close to or away from the second support frame 420.

[0034] The aligner is mainly used to detect the distance between the tool 320 and the axis of the transmission sleeve 110. In this embodiment, the aligner includes a receiving plate 311 and a laser emitter 312. The receiving plate 311 is disposed at least on one side of the moving path of the movable seat 337, and the adjusting seat 331 is connected with the laser emitter 312 corresponding to the position of the receiving plate 311. When the outer sleeve 334 or the screw 336 is deformed and the movable seat 337 moves to the deformed position, the position where the tool 320 feeds into the pipe body will shift. At this time, the emitter on the adjusting seat 331 shifts the emission point to the receiving plate 311. According to the position where the receiving plate 311 receives the laser, the offset value between the tool 320 and the axis of the transmission sleeve 110 can be obtained. The adjusting seat 331 performs radial movement compensation according to this offset value to achieve precise machining of the inner wall of the pipe body.

[0035] The feed regulator needs to control the radial movement of the adjusting seat 331 to adjust the feed direction of the tool 320. The control mode of the feed regulator for the adjusting seat 331 can be to directly drive the adjusting seat 331 to move radially along the pipe body. At this time, the feed regulator requires a relatively large radial space, which is not conducive to the use of pipe bodies with a small diameter. Therefore, in order to reduce the required installation space of the feed regulator, the transmission mode for the adjusting seat 331 can be adjusted. Specifically, the feed regulator includes an adjusting screw 361 and an adjusting rod 362. The adjusting screw 361 is connected to the movable seat 337, the adjusting screw 361 is drivingly connected to the adjusting rod 362, the adjusting screw 361 can drive the adjusting rod 362 to move in a direction away from or close to the transmission sleeve 110, a guiding section 363 is formed on the adjusting rod 362 and extends obliquely in a direction away from the axis of the transmission sleeve 110, the adjusting seat 331 is slidably connected to the movable seat 337 along the radial direction of the transmission sleeve 110, and the guiding section 363 is inserted into the adjusting seat 331. The adjusting screw 361 adjusts the position of the adjusting rod 362 along the axial direction of the pipe body, which can reduce the required radial installation space of the adjusting screw 361 and the adjusting rod 362 in the outer sleeve 334, so as to compactly install the driving source for driving the adjusting seat 331 into the outer sleeve 334. When it is necessary to increase the feed depth of the tool 320 into the pipe body, the adjusting screw 361 drives the adjusting rod 362 to approach the adjusting seat 331. Since the guiding section 363 on the adjusting rod 362 is inclined in a direction away from the axis of the transmission sleeve 110, the guiding section 363 can guide the adjusting seat 331, so that the tool 320 on the adjusting seat 331 approaches the inner wall of the pipe body further. When it is necessary to reduce the feed depth of the tool 320 into the pipe body, the adjusting screw 361 drives the adjusting rod 362 to move in a direction away from the adjusting seat 331. Similarly, the guiding section 363 guides the adjusting seat 331, so that the tool 320 on the adjusting seat 331 moves in a direction away from the inner wall of the pipe body. In this way, the radial movement adjustment of the tool 320 can be realized.

[0036] The rotating device 100 is provided with a driving source for driving the transmission sleeve 110 to rotate. Specifically, as Figure 4 shown, the rotating device 100 includes a base frame 120 and a second motor 130. A fixed sleeve 140 is connected to the base frame 120. The transmission sleeve 110 is rotatably connected within the fixed sleeve 140. The second motor 130 is connected to the base frame 120, and the second motor 130 is in transmission connection with the transmission sleeve 110. In practical applications, the output shaft of the second motor 130 and the end of the transmission sleeve 110 can be in meshing transmission through gears, so as to drive the transmission sleeve 110 to rotate self - sufficiently by using the second motor 130. In order to avoid the outer sleeve 334, the middle part of the second gear has an avoidance hole through which the outer sleeve 334 can pass. The transmission sleeve 110 is rotatably installed within the fixed sleeve 140, which can improve the installation stability of the transmission sleeve 110. During operation, the second motor 130 provides a rotational driving force to the transmission sleeve 110, driving the transmission sleeve 110 to rotate, and then driving the pipe body to rotate through the pipe - clamping device 200.

[0037] The pipe - clamping device 200 provides an openable and closable pipe - clamping area to clamp and fix or release the pipe body. There are various structural forms. For example, the pipe - clamping device 200 is a clamp installed on the transmission sleeve 110. In order to improve the convenience of clamping the pipe body, in this embodiment, the pipe - clamping device 200 is a three - jaw chuck. The three - jaw chuck has three jaws that can move away from or close to each other. An openable and closable pipe - clamping area is formed between the three jaws. When the three jaws move away from each other, the pipe - clamping area is opened, and the feeding or discharging of the pipe body can be carried out. When the three jaws move close to each other, the pipe - clamping area is closed, realizing the clamping of the pipe body.

[0038] The present invention further includes a limiting frame 610. Inside the limiting frame 610, a plurality of limiting wheels 620 are circumferentially arrayed around the axis of the transmission sleeve 110. A limiting area is formed by enclosing among the plurality of limiting wheels 620. The limiting area is opposite to the pipe clamping area. Naturally, in order to enable the pipe body to rotate smoothly within the limiting area, the rotation axes of the plurality of limiting wheels 620 are parallel to the rotation axis of the pipe body. Thus, while the plurality of limiting wheels 620 limit the pipe body on the outer side thereof, the rotational friction with the pipe body is reduced. When loading the pipe body, the pipe body can enter into the limiting area. By using the plurality of limiting wheels 620 to abut against the outer wall of the pipe body, support is provided for the pipe body. In this way, by using the limiting frame 610 to provide support for the outer side of the pipe body, the rotational stability of the pipe body can be improved. In practical applications, the limiting frame 610 includes a fixed part and a rotating part rotatably connected to the fixed part. The rotating part can rotate and close towards the direction close to the fixed part, or rotate and open towards the direction away from the fixed part. Limiting wheels 620 are respectively connected to the rotating part and the fixed part. When it is necessary to place the pipe body, the rotating part can be rotated and opened from the fixed part. At this time, the limiting area is opened, and the pipe body can be conveniently placed. Then, the rotating part is rotated and close towards the fixed part, and the rotating part and the fixed part are fastened by means such as screws and buckles, so as to limit the pipe body within the limiting area. In addition, the position of the limiting wheel 620 on the limiting frame 610 can be fixed, or an adjusting structure such as a hand-operated lead screw is installed on the limiting frame 610. The limiting wheel 620 is installed on the hand-operated lead screw, and the position of the limiting wheel 620 can be adjusted by the hand-operated lead screw, so as to adjust the size of the limiting area formed by enclosing.

[0039] Further, a plurality of limiting frames 610 are arranged at intervals along the direction away from the pipe clamping area. The number of the limiting frames 610 can be set according to the length of the pipe body. When the length of the pipe body is longer, the number of the limiting frames 610 is more. For example, the number of the limiting frames 610 can be two or three, etc. The plurality of limiting frames 610 can provide support at different positions of the pipe body, effectively preventing the pipe body from bending downward and deforming due to excessive length, and further improving the rotational stability of the pipe body.
