Description

Technical Field

[0001] This invention belongs to the technical field of pipe processing clamping equipment, specifically a metal pipe processing equipment and an outer circle centering clamp assembly. Background Technology

[0002] Traditional pipe processing fixtures rely solely on a single rigid clamping structure, making it difficult to adapt to pipes of different diameters. Furthermore, manual adjustment of the clamping stroke results in large errors and inaccurate control of the clamping force, which can easily lead to pipe deformation due to excessive clamping force or processing deviation due to insufficient clamping force. In addition, traditional processing equipment does not integrate processing, clamping, and waste collection into a coordinated design, resulting in processing waste easily scattering and polluting the working environment. Moreover, the processing position is inconvenient to adjust, leading to low processing efficiency and poor process adaptability.

[0003] Patent application number CN202410113856.3 discloses an external cylindrical positioning fixture for steel pipe processing, relating to the field of steel pipe positioning fixture technology. It includes a positioning frame mounted on a machine tool. Multiple sets of sliding holes are formed through the outer side of the positioning frame. Multiple sets of locking rods are fixedly installed on the outer side of the positioning frame. The locking rods are correspondingly arranged with the sliding holes. Multiple sets of locking holes are formed inside the locking rods. A sliding rod is slidably connected inside the sliding holes. A top spring is provided between the sliding rod and the inner wall of the positioning frame. A swing arm is rotatably mounted at the bottom of the sliding rod, and an arc-shaped clamping plate is provided at the bottom of the swing arm. The above solution only requires inserting the steel pipe to clamp it, completing the outer circle positioning and clamping of the steel pipe. No other operation or drive source is required, making clamping convenient and not affecting the steel pipe processing. Furthermore, the rolling angle of the arc-shaped clamping plate can accurately determine the clamping length of the steel pipe, thus enabling fixed-distance clamping and making clamping more convenient. Although the above solution achieves positioning and clamping of the outer circle, during the clamping process, the vibration causes the pipe's axis to shift, and the inability to make timely fine adjustments to the pipe's position leads to problems with processing accuracy.

[0004] Meanwhile, conventional fixtures lack flexible auxiliary support and pipe wall protection structures. Rigid contact can easily cause damage to the pipe surface and insufficient centering accuracy, making it impossible to ensure that the center of the circle is coaxial with the machining center during processing, thus affecting the processing quality.

[0005] Therefore, in order to solve the above-mentioned technical problems, the present invention proposes a metal pipe processing equipment and an outer circle centering fixture assembly. Summary of the Invention

[0006] The purpose of this invention is to address the above-mentioned problems. This invention provides a metal pipe processing equipment and an outer circle centering clamp assembly, which has the advantage of achieving precise and stable clamping of pipes of various specifications.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a metal pipe processing equipment, including a support assembly, a processing assembly for processing pipes connected to the support assembly, the support assembly including a support frame, a protective frame connected to the support frame, and the processing assembly connected to the support frame, wherein a clamping assembly for restricting the pipes is connected to one end of the protective frame near the processing assembly; The clamping assembly includes a rotating shaft, one end of which is connected to the protective frame, and the end of the rotating shaft away from the protective frame is connected to a rotating component. The end of the rotating component away from the rotating shaft is connected to a plurality of snap-fit ​​parts for restricting the pipe. The rotating assembly includes a support plate, one end of which is connected to the rotating shaft, and the end of the support plate away from the rotating shaft is provided with multiple limiting grooves of different sizes; The processing equipment also includes an intelligent controller for coordinated operation.

[0008] Preferably, the plurality of the snap-fit ​​parts are arranged in a circumferential array on the carrier plate, and the snap-fit ​​parts are capable of abutting against limiting grooves of different sizes.

[0009] Preferably, a material collection component for collecting waste is connected between the clamping component and the processing component. The material collection component includes a material collection pipe, and a collection box for collecting waste is provided on one side of the material collection pipe.

[0010] Preferably, the snap-fit ​​part includes a fixed rail connected to the bearing plate, a movable rail slidably disposed on the fixed rail, and an abutment part for abutting against the outer circle of the pipe is connected to one end of the movable rail that is close to each other. A supplementary plate for increasing the contact area of ​​the abutment part is provided between the abutment part and the movable rail through a connecting rod.

[0011] Preferably, the processing assembly includes a slide rail, one end of which is fixedly connected to the support frame. A movable frame for changing the processing position is slidably connected to the slide rail. A drive motor is connected to the movable frame, and a processing head for processing the pipe is connected to the drive end of the drive motor.

[0012] The present invention also discloses an outer circle centering clamp assembly for a metal pipe processing equipment, comprising a plurality of auxiliary components for providing secondary support for the pipe wall, the auxiliary components being movably connected to the clamping assembly; The auxiliary components include a limiting plate, a connecting plate, and a clamping plate for protecting and restricting the pipe. The adjacent areas of the limiting plate, the connecting plate, and the clamping plate are connected by a sliding rod, and one side of each of the limiting plate, the connecting plate, and the clamping plate is connected to a spring for abutting against the outer circle of the pipe. The auxiliary component also includes a snap-fit ​​groove connected to the clamping component, the snap-fit ​​groove passing through the limiting plate, the connecting plate and the clamping plate respectively.

[0013] Preferably, both the limiting plate and the connecting plate have grooves on their side ends for the movement of the sliding rod.

[0014] Preferably, one end of the limiting plate, the connecting plate, and the clamping plate is provided with a connecting groove, and the spring is slidably connected in the connecting groove.

[0015] Preferably, a telescopic assembly for controlling the movement of the spring is connected between the connecting groove and the spring. The telescopic assembly includes a telescopic rod, and an identification part for identifying the pressure of the spring is connected to one end of the telescopic rod near the spring. The identification part is connected to the spring.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. The clamping assembly's carrier plate is equipped with limiting grooves of different sizes to initially adapt to pipes of different diameters. The circumferentially arrayed snap-fit ​​parts slide synchronously along the fixed and movable rails radially. The contact part, with the supplementary plate, increases the contact area and reduces local pressure. Combined with the pressure feedback and automatic stroke adjustment of the intelligent controller, it can avoid pipe deformation caused by excessive clamping force and prevent processing deviation caused by insufficient clamping force. At the same time, the rotating shaft drives the carrier plate and the pipe to rotate synchronously, and together with the processing assembly, it can achieve full circumferential processing. The entire process from positioning, clamping to rotation is coordinated, which greatly improves the clamping versatility and processing position stability of pipes of different specifications.

[0017] 2. The slide rails and movable frame of the processing components can flexibly adjust the horizontal and vertical positions of the processing head. The plug-in processing head can be quickly replaced to adapt to different processes such as cutting and grinding. The drive motor provides stable power for processing and works in conjunction with the rotation function of the clamping components to achieve uniform processing of the pipe surface. The material receiving component's receiving pipe and collection box are located between the processing and clamping components, which can collect processing waste in real time. The waste is guided by the receiving pipe and falls into the collection box. The movable collection box is easy to clean in time. The linkage between the two ensures processing accuracy and efficiency, and avoids waste scattering and polluting the environment, so that processing and waste collection are completed simultaneously and efficiently.

[0018] 3. The auxiliary components are movably connected to the movable rail of the clamping components via snap-fit ​​grooves. The limiting plate, connecting plate, and clamping plate achieve layered telescopic movement via sliding rods and sliding grooves. In conjunction with the flexible contact of the springs against the outer circle of the tube, the telescopic rods of the telescopic components and the identification part adjust the contact force and bending degree of the springs in real time. The intelligent controller synchronously links the clamping and auxiliary components to ensure that the center of the tube is always coaxial with the machining center. Furthermore, the springs replace rigid contact to avoid scratches and dents on the tube wall. The combination of multi-layer plates and springs forms secondary support, which, together with the main positioning function of the clamping components, improves the centering accuracy and effectively prevents deformation of the tube during processing, thus balancing the centering effect and tube wall protection.

Detailed Implementation

[0021] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. 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.

[0022] Example 1 like Figure 1 - Figure 6 As shown, the present invention discloses a metal tube processing equipment, including a support component 1 for maintaining the stability of the components, and a processing component 3 for processing the tube connected to the support component 1. The support component 1 includes a support frame 101, and a protective frame 102 for protecting electronic components is connected to the support frame 101. The processing component 3 is connected to the support frame 101, wherein the protective frame 102 and the processing component 3 are respectively located on both sides of the support frame 101 along its length. A clamping component 4 for restricting the end of the tube is connected to one end of the protective frame 102 near the processing component 3. When processing the tube, the end of the tube is connected to the clamping component 4, and then the tube is processed using the processing component 3.

[0023] The clamping assembly 4 includes a rotating shaft 401 for providing driving force. One end of the rotating shaft 401 is rotatably connected to the protective frame 102, which maintains the rotational position of the rotating shaft 401. The end of the rotating shaft 401 away from the protective frame 102 is connected to a rotating component 402 for driving the pipe to rotate. The end of the rotating component 402 away from the rotating shaft 401 is slidably connected to a plurality of locking parts 403 for limiting the outer circle of the pipe. The plurality of locking parts 403 are arranged in a circumferential array on the bearing plate 4021, and the ends of the locking parts 403 face the axis of the rotating shaft 401. When the end of the pipe abuts against the rotating component 402, relative sliding occurs between the driving locking parts 403 and the rotating component 402, thereby limiting the contact of the outer circle of the pipe, maintaining the stability of the pipe on the processing equipment, and ensuring that the processing assembly 3 can meet the processing requirements of the pipe.

[0024] Meanwhile, to achieve intelligent and precise control of the clamping process, the processing equipment is equipped with an intelligent controller. The controller is electrically connected to the drive mechanism of the clamping part 403. The pipe diameter parameter can be input through a preset program to automatically control the sliding stroke of the clamping part 403. At the same time, the contact pressure signal between the clamping part 403 and the outer circle of the pipe is collected in real time. The clamping force is adjusted through feedback to ensure that it is within the preset threshold range, so as to avoid the problem of pipe deformation due to excessive clamping force and pipe slippage due to insufficient clamping force.

[0025] Furthermore, during use, when the diameter of the fixed pipe remains constant, the clamping force is adjusted, the displacement deviation during pipe processing is recorded, and the optimal clamping force range is determined. When the fixed clamping force remains constant, different diameter pipes are adapted to verify the accuracy of the sliding stroke adjustment of the clamping part 403, thus solving the technical problems of poor compatibility of clamping different specifications of pipes and large errors in manual adjustment.

[0026] The rotating assembly 402 includes a bearing disk 4021 for providing radial stability. One end of the bearing disk 4021 is connected to the rotating shaft 401, which drives the bearing disk 4021 to rotate. The end of the bearing disk 4021 away from the rotating shaft 401 is provided with multiple limiting grooves 4022 of different sizes, and the pipe can be engaged with the limiting grooves 4022 to limit pipes of different diameters. The end of the engaging part 403 can abut against the limiting grooves 4022 of different sizes.

[0027] The intelligent controller is electrically connected to the drive mechanism of the rotating shaft 401, which can precisely control the rotation speed and rotation angle of the rotating shaft 401. When the processing parameters of the fixed processing head 303 remain unchanged, the rotation speed of the rotating shaft 401 is adjusted, the roughness of the pipe processing surface is recorded, and the optimal rotation speed corresponding to different pipe diameters is determined.

[0028] When the fixed rotation speed remains constant, the step value of the rotation angle is adjusted to observe the coverage integrity of the processing area, thereby solving the technical problems of insufficient flatness of the pipe processing surface and omission of processing areas. At the same time, the controller can automatically switch the rotation mode of the rotating shaft 401 according to the progress of pipe processing, realizing the intelligent switching between continuous rotation and intermittent rotation to adapt to different processing requirements.

[0029] In use, firstly, according to the diameter requirements of the pipe to be processed, pipes of different diameters are matched with the corresponding limiting grooves 4022, and multiple limiting grooves 4022 are moved synchronously to clamp and fix the outer circle of the pipe. Then, the processing component 3 processes the pipe. As the processing needs of the processing component 3 are met, the rotating shaft 401 drives the rotating component 402 and the pipe to rotate, thereby changing the contact area between the processing component 3 and the outer circle of the pipe, thus achieving the processing requirements of the pipe. At the same time, the intelligent controller can store the processing parameters of various pipe specifications. The operator only needs to select the pipe model, and the equipment can automatically complete the adaptation of the limiting grooves 4022, the clamping adjustment of the clamping part 403, and the speed setting of the rotating shaft 401. There is no need for manual adjustment of each component, which greatly improves the processing efficiency.

[0030] Furthermore, to improve the cleanliness of the work area, a collection component 6 is connected between the clamping component 4 and the processing component 3 to collect waste generated during pipe processing. The collection component 6 includes a collection pipe 601 for waste collection and movement. When the processing component 3 processes the pipe, the waste generated can fall into the collection pipe 601. At the same time, a collection box 602 for collecting waste is provided on one side of the collection pipe 601, and the collection box 602 is movably connected to the side of the support frame 101 near the ground, so that the user can clean the waste in the collection box 602 in a timely manner according to the waste collection status.

[0031] Furthermore, in order to clamp and fix pipes of different diameters, the clamping part 403 includes a fixed rail 4031 for limiting the movement trajectory. The fixed rail 4031 is connected to the support plate 4021, wherein the support plate 4021 has a groove for the fixed rail 4031 to connect, so as to prevent the clamping part 403 from protruding too much from the support plate 4021, thereby affecting the processing space of the pipe. A movable rail 4032 for length extension is slidably provided on the fixed rail 4031, wherein the fixed rail 4031 can slide relative to the support plate 4021 to change the connection position of the fixed rail 4031 on the support plate 4021, ensuring that the fixed rail 4031 will not interfere with the connection of the pipe. When the diameter of the pipe is small, the relative movement between the movable rail 4032 and the fixed rail 4031 is controlled to increase the length of the fixed rail 4031 and the movable rail 4032, ensuring that they can abut against the outer circle of the pipe, thereby restricting the position of the pipe.

[0032] It should be noted that the movement methods of the fixed rail 4031 and the movable rail 4032 are existing technologies and will not be elaborated on here.

[0033] Specifically, to enhance the constraint force on the pipe, the movable rails 4032 are connected at their closest ends to a contact part 4034 for contacting the outer circumference of the pipe. The contact part 4034 contains a pressure sensor for detecting the contact force. By using the fixed rails 4031 and 4032 to change the position of the contact part 4034 on the support plate 4021, the position of the contact part 4034 on the support plate 4021 is ensured to contact the outer circumference of the pipe, thus achieving positional constraint on the pipe. Furthermore, to increase the contact area between the contact part 4034 and the pipe, the pressure sensor is reduced. The pressure on the surface of the weak pipe is reduced, and a supplementary plate 4033 is provided between the contact part 4034 and the movable rail 4032 via a connecting rod to increase the contact area of ​​the contact part 4034. When the end face of the contact part 4034 comes into contact with the outer circle of the pipe, the contact part 4034 triggers the connecting rod, thereby using the connecting rod to drive the supplementary plate 4033 to rotate, so that the end face of the supplementary plate 4033 is flush with the end of the contact part 4034, increasing the contact area with the pipe and thus reducing the possibility of pipe deformation during clamping.

[0034] Furthermore, the intelligent controller is electrically connected to the pressure sensor of the contact part 4034 and the connecting rod of the supplementary plate 4033, and collects the contact pressure between the contact part 4034 and the pipe in real time. When the pressure reaches the preset value, the supplementary plate 4033 is automatically triggered to rotate, ensuring that the contact area increases in a timely manner.

[0035] Specifically, when the diameter of the fixed pipe remains unchanged, the rotation angle of the supplementary plate 4033 is adjusted, the pressure change on the pipe surface is recorded, the optimal rotation angle is determined, and the problem of surface damage and deformation caused by excessive local pressure during pipe clamping is solved. At the same time, the controller can adjust the trigger pressure threshold of the supplementary plate 4033 according to the material parameters of the pipe to adapt to metal pipes of different hardness and improve the versatility of clamping.

[0036] Furthermore, in order to improve the processing efficiency of the pipe, the processing component 3 includes a slide rail 301 for changing the distance between the processing component 3 and the clamping component 4. One end of the slide rail 301 is fixedly connected to the support frame 101. A movable frame 304 for changing the processing position is slidably connected to the slide rail 301. The movable frame 304 is slidably connected to the slide rail 301. At the same time, the movable frame 304 is also provided with an area for the processing head 303 to move vertically to the slide rail 301. A drive motor 302 is connected to the movable frame 304. The drive end of the drive motor 302 is connected to the processing head 303 for processing the pipe. The processing head 303 is inserted into the drive motor 302, which facilitates the quick replacement of the processing head 303. At the same time, it can be replaced with a suitable processing head 303 in a timely manner according to the processing requirements of the pipe to meet the processing requirements of the pipe.

[0037] In use, the entire machine's functional components are supported by the support assembly 1. The support frame 101 serves as the main support base, with the protective frame 102 and processing assembly 3 arranged on both sides of the support frame 101 along its length. The protective frame 102 provides isolation and protection for the internal electronic components of the equipment and also provides a reference for the installation and rotation of the clamping assembly 4. Before operation, the operator, according to the actual diameter of the metal pipe to be processed, clamps the end of the pipe into the corresponding size limiting groove 4022 opened in the bearing plate 4021 of the rotating assembly 402. The limiting grooves 4022 of different specifications are used to achieve the initial positioning and adaptation of pipes of multiple diameters.

[0038] Subsequently, the device presets the pipe diameter parameters through the intelligent controller. The controller synchronously links the drive mechanism of the clamping part 403 to automatically adjust the sliding stroke. Multiple sets of clamping parts 403, arranged in a circumferential array on the bearing plate 4021, slide synchronously towards the axis radially. The fixed rail 4031 is stably installed by relying on the groove of the bearing plate 4021 and can be finely adjusted relative to the bearing plate 4021 to avoid interference in pipe assembly. The movable rail 4032 slides relative to the fixed rail 4031 to adapt to the radial contact stroke requirements of small-diameter pipes. The contact part 4034 gradually fits the outer circle of the pipe as it slides. The pressure sensor built into the contact part 4034 collects the contact pressure signal in real time and sends it back to the intelligent controller. The controller adjusts the clamping force in real time through closed-loop feedback to keep the clamping force always within the preset threshold range, effectively avoiding the defects of pipe deformation caused by excessive clamping force and pipe slippage caused by insufficient clamping force.

[0039] When the contact pressure reaches the set trigger value, the intelligent controller automatically controls the connecting rod to rotate the supplementary plate 4033 to be flush with the end of the contact part 4034, thereby increasing the contact area with the outer circle of the pipe and reducing the local contact pressure. At the same time, the controller can also adaptively adjust the pressure trigger threshold of the supplementary plate 4033 according to the hardness parameter of the metal pipe itself, so as to adapt to the clamping and protection requirements of metal pipes of different materials.

[0040] After the pipe is precisely clamped and positioned, the processing component 3 adjusts its overall horizontal position using the slide rail 301. The movable frame 304 slides along the slide rail 301 to change the distance between the processing station and the end of the pipe. The drive motor 302 is mounted on the movable frame 304 and can drive the processing head 303 to finely adjust its working position along the vertical slide rail 301. The processing head 303 adopts a plug-in assembly structure, which enables quick disassembly and replacement. The corresponding processing head 303 can be flexibly matched according to different processing conditions such as pipe cutting and grinding to ensure the adaptability of the processing technology.

[0041] During pipe processing, the intelligent controller establishes an electrical control linkage with the drive mechanism of the rotating shaft 401, precisely controlling the operating speed and step rotation angle of the rotating shaft 401. The rotating shaft 401 maintains the stability of its rotation position with the help of the protective frame 102, and drives the bearing plate 4021 and the clamped and fixed metal pipe to rotate synchronously. Under the premise of fixed processing head 303 process parameters, the equipment can calibrate the optimal rotation speed corresponding to different pipe diameters to reduce the surface roughness of the pipe processing. It can also optimize the step value of the rotation angle under constant speed to eliminate defects such as missed processing areas and insufficient flatness of the pipe surface. At the same time, the intelligent controller can automatically switch the operation mode of the rotating shaft 401 according to the real-time processing progress of the pipe, intelligently switching between continuous rotation and intermittent rotation to adapt to diverse processing requirements.

[0042] At the same time, the receiving component 6 participates in the operation. The waste generated during the pipe processing naturally falls into the receiving pipe 601. After being collected and guided by the receiving pipe 601, it falls into the collection box 602. The collection box 602 adopts a movable connection structure, which makes it easy for workers to disassemble and clean it in time according to the amount of waste accumulated, effectively maintaining the cleanliness of the equipment operation area.

[0043] Example 2 In the process of clamping the pipe using the solution in Embodiment 1, although the position of the pipe is limited, the pipe is prone to abnormal deformation due to the influence of the clamping position. Therefore, in order to avoid pipe wall deformation during the clamping process and affect the normal use of the pipe, the present invention proposes the following technical solution.

[0044] like Figure 3 , Figure 7 - Figure 9 As shown, the present invention also discloses an outer circle centering clamp assembly for a metal pipe processing equipment, which is used to maintain the position of the pipe and ensure the stability of the pipe's center during processing. It includes multiple auxiliary components 5 for secondary support of the pipe wall. The auxiliary components 5 are movably connected to the clamping assembly 4, and the number of auxiliary components 5 is the same as the number of clamping assemblies 4. The auxiliary components 5 work in conjunction with the clamping assembly 4 to constrain and clamp the outer circle of the pipe, maintain a constant processing position between the pipe and the processing assembly 3, and prevent damage to the outer circle of the pipe during the clamping and limiting process.

[0045] Specifically, the auxiliary component 5 includes a limiting plate 501, a connecting plate 502, and a clamping plate 503 for protecting and restricting the pipe. When the outer diameter of the pipe is not clamped, the positions of the limiting plate 501, the connecting plate 502, and the clamping plate 503 are superimposed, i.e., they are distributed in concentric circles, and their positions do not interfere with each other. Furthermore, the adjacent areas of the limiting plate 501, the connecting plate 502, and the clamping plate 503 are connected by a sliding rod 504 to ensure that the auxiliary component 5 can ensure the normal displacement of the connecting plate 502 and the clamping plate 503 during use, thus satisfying the requirements for protecting the outer diameter of the pipe. The outer circle of the pipe is limited by a spring 506 connected to one side of the limiting plate 501, connecting plate 502, and clamping plate 503. This increases the stability of the auxiliary component 5 when limiting the outer circle of the pipe, and at the same time avoids the limiting plate 501, connecting plate 502, and clamping plate 503 from directly contacting the surface of the pipe when limiting the pipe, which would affect the positioning accuracy of the pipe. That is, the spring 506 replaces the limiting plate 501, connecting plate 502, and clamping plate 503 in contacting the surface of the pipe. The connection accuracy of the pipe can be adjusted by adjusting the position of the spring 506.

[0046] To ensure that the auxiliary component 5 can effectively constrain the pipe, in this solution, the limiting plate 501, the connecting plate 502, and the clamping plate 503 are all arc-shaped.

[0047] The auxiliary component 5 also includes a snap-fit ​​groove 5011 connected to the clamping component 4. The snap-fit ​​groove 5011 passes through the limiting plate 501, the connecting plate 502, and the clamping plate 503 respectively. The snap-fit ​​groove 5011 of the limiting plate 501 has a movable part that can move between the movable rail 4032 and the auxiliary component 5 on the clamping component 4 to adapt to pipes of different diameters. At the same time, the snap-fit ​​grooves 5011 on the connecting plate 502 and the clamping plate 503 only contact the clamping component 4 and do not make a substantial connection to ensure that they can move stably between the limiting plate 501 and the clamping component 4.

[0048] Furthermore, both the limiting plate 501 and the connecting plate 502 have sliding grooves 507 on their side ends for the sliding rod 504 to move, ensuring that the moving path of the connecting plate 502 and the clamping plate 503 is stable, and can work together with the limiting plate 501 to constrain the outer circle of the pipe.

[0049] Furthermore, a connecting groove 505 is provided at one end of the limiting plate 501, the connecting plate 502 and the clamping plate 503, and the spring 506 is slidably connected in the connecting groove 505.

[0050] Furthermore, to ensure the normal operation of the spring 506 and to allow for fine adjustments to the pipe position, a telescopic assembly 7 for controlling the movement of the spring 506 is connected between the connecting groove 505 and the spring 506. The telescopic assembly 7 includes a telescopic rod 701, with an identification part 702 for identifying the pressure of the spring 506 connected to one end of the telescopic rod 701 near the spring 506. The identification part 702 is connected to the middle area of ​​the spring 506 and contains a hybrid sensor group, which includes a pressure sensor and a displacement sensor. During use, the length of the telescopic rod 701 is adjusted according to the connection position of the pipe, thereby changing the curvature of the spring 506 and thus changing the contact force between the spring 506 and the pipe surface. This ensures the stability of the pipe's position during the connection process and meets the processing requirements of the processing assembly 3.

[0051] Furthermore, in this embodiment, the outer circle centering clamp assembly establishes an electrical control linkage with the intelligent controller in Embodiment 1 to achieve intelligent and precise control of the auxiliary clamping process. The intelligent controller is electrically connected to the telescopic rod 701 of the telescopic assembly 7 and the hybrid sensor group in the identification unit 702. It can collect the pressure signal and displacement signal fed back by the identification unit 702 in real time. Combined with preset parameters such as the diameter and material of the pipe, it automatically adjusts the telescopic rod 701 to precisely control the bending degree and contact force of the spring 506. This avoids the problem of pipe wall indentation due to excessive contact force of the spring 506 and pipe centering deviation due to insufficient contact force. At the same time, it realizes the coordinated control of the auxiliary assembly 5 and the clamping assembly 4 to ensure that the center of the pipe is coaxial with the processing center of the processing assembly 3 when the pipe is clamped, thereby improving the processing accuracy.

[0052] Specifically, based on the fixed pipe diameter and material, the resistance force of the auxiliary component 5 is adjusted: the pipe diameter and material are kept constant, and the extension and retraction of the telescopic rod 701 are gradually adjusted by the intelligent controller to change the resistance force of the spring 506 on the pipe. The pressure data collected by the identification unit 702, the pipe's center offset, and the degree of pipe wall deformation are recorded in real time to determine the optimal resistance force range for pipes of different diameters, thereby ensuring that pipe wall deformation is minimized while maintaining stable centering.

[0053] The extension and retraction of the telescopic rod 701 is kept constant, that is, the contact force of the spring 506 is kept constant. When replacing the pipes of the same material with different diameter specifications, the displacement sensor of the identification unit 702 collects the deformation displacement data of the spring 506. Combined with the pipe diameter parameters preset by the intelligent controller, the movement adaptability of the auxiliary component 5 through the snap-fit ​​groove 5011 and the movable rail 4032 is verified. At the same time, the pipe centering accuracy is recorded, the movement stroke threshold of the auxiliary component 5 is optimized, and the versatility of the clamping component is improved.

[0054] Meanwhile, by keeping the diameter of the control tube and the contact force of the spring 506 constant, and by replacing metal tubes with different hardness and materials, the pressure sensor of the identification unit 702 monitors the contact pressure between the spring 506 and the surface of the tube in real time. The intelligent controller automatically fine-tunes the extension and retraction of the telescopic rod 701 according to the pressure threshold preset by the tube material, compensates for the difference in elastic deformation of tubes of different materials, records the surface damage and centering stability of the tube after processing, and realizes precise centering clamping of tubes of multiple materials.

[0055] In addition, the intelligent controller can store the adjustment parameters of the auxiliary component 5 corresponding to pipes of different specifications and materials. Operators only need to select the pipe model and material in the controller, and the equipment can automatically complete the position adjustment of the auxiliary component 5, the extension and retraction setting of the telescopic rod 701, and the calibration of the contact force of the spring 506. There is no need for manual adjustment of the auxiliary component 5 one by one, which greatly improves the convenience of operation and the centering efficiency. At the same time, the intelligent controller has an abnormal alarm function. When the pressure signal or displacement signal collected by the identification unit 702 exceeds the preset threshold, the controller will issue an alarm prompt in time and automatically adjust the extension and retraction of the telescopic rod 701 to avoid damage to the pipe or abnormal processing accuracy, further improving the safety and reliability of the equipment.
