Description

Technical Field

[0001] This application relates to the field of ring alignment technology, and in particular to a ring alignment fixture and alignment method. Background Technology

[0002] During the production of large-sized metal rings (i.e., ring-shaped workpieces), both cold and hot working processes will generate certain internal stresses on the rings, causing a certain degree of elliptical deformation. When the deformation exceeds the machining allowance, the rings face the risk of being scrapped. Therefore, it is necessary to correct (or round) the rings to reduce their deformation and make them meet the requirements of subsequent processing.

[0003] Generally, methods for correcting workpiece deformation can be divided into two types. One is the heat treatment correction method. Common heat treatment correction methods include heating and quenching at Ac1 temperature to shrink bulging deformations and quenching to expand shrinking deformations. For large workpieces, this correction method is often time-consuming and labor-intensive, with relatively low correction efficiency. The other is the mechanical correction method, which uses mechanical or localized heating to induce localized micro-plastic deformation in the deformed workpiece, simultaneously releasing and redistributing residual internal stress to achieve the purpose of deformation correction. Common mechanical correction methods include cold pressing correction, hot pressing correction before quenching and cooling to room temperature, pressure tempering correction, "hot spot" correction using oxy-acetylene flame or high frequency to locally heat the deformed workpiece, and hammering correction. Among these, cold pressing correction achieves the correction effect by applying load to the deformed part of the ring using correction equipment. This correction method has a wide range of applications and relatively high correction efficiency.

[0004] However, the cold-pressing calibration fixtures in related technologies cannot measure the deformation of the ring to be calibrated. Other methods are needed to measure the deformation of the ring and record the deformation data to guide the selection of the calibration area. Each calibration requires measurement by other methods, which is time-consuming and labor-intensive and cannot meet the production needs of efficient measurement and calibration of rings with large diameter spans. Summary of the Invention

[0005] This application provides a calibration fixture and calibration method for a ring component to solve the problem of inconsistency between measurement and calibration of deformed ring components.

[0006] To achieve the above objectives, in a first aspect, this application provides a ring correction fixture for correcting a ring that has been deformed into an ellipse. The ring correction fixture includes a first support assembly, a second support assembly, a measuring assembly, a pushing assembly, and a controller.

[0007] The first support assembly, the second support assembly, and the measuring assembly are used to jointly support the deformed ring, and the jacking assembly is located at the center of the circle formed by the first support assembly, the second support assembly, and the measuring assembly;

[0008] The first support assembly and the second support assembly jointly drive the ring to rotate around the center. The first support assembly, the second support assembly, the measuring assembly, and the pushing assembly are all electrically connected to the controller. The measuring assembly is used to contact the ring and detect the radius of the ring to determine the short axis of the ring. The controller controls the first support assembly and the second support assembly to rotate the position of the short axis of the ring to be opposite to the pushing assembly, and controls the pushing assembly to extend to both sides to open the position of the short axis of the ring.

[0009] In one possible implementation, the first support assembly includes a first support platform and a first idler roller disposed on the first support platform;

[0010] The second support assembly includes a second support platform and a second idler roller disposed on the second support platform;

[0011] The measuring assembly includes a measuring table, a third idler roller, and a measuring element. Both the third idler roller and the measuring element are set on the measuring table. The measuring element is used to measure the outer or inner radius of the ring. The pushing assembly includes a telescopic component and two pushing elements respectively set at both ends of the telescopic component. The telescopic component is set at the center of the ring. The pushing elements are used to open the short axis position of the ring.

[0012] The first support platform, the second support platform, and the measuring platform form a circle. The first idler roller, the second idler roller, and the third idler roller jointly support the ring component, and the first idler roller and the second idler roller drive the ring component to rotate. The first idler roller, the second idler roller, the measuring component, and the telescopic component are all electrically connected to the controller.

[0013] In one possible implementation, the first support component and the second support component are arranged opposite each other and are located on opposite sides of the center of the circle;

[0014] There are two measuring components, which are located between the second support component and the first support component, and the measuring elements are respectively located on the vertical line connecting the first idler roller and the second idler roller.

[0015] In one possible implementation, the first support assembly further includes a first reference roller, the second support assembly further includes a second reference roller, and the measuring assembly further includes a measuring center roller. The first reference roller is erected on the first support platform, the second reference roller is erected on the second support platform, and the measuring center roller is erected on the measuring platform.

[0016] The first reference roller, the second reference roller, and the measuring center roller abut against the outer surface of the ring.

[0017] In one possible implementation, a support platform is also included, wherein the first support platform, the second support platform, and the measuring platform are respectively mounted on the support platform in a radially movable manner.

[0018] In one possible implementation, the first support assembly further includes a first drive member for driving the first support platform to move radially;

[0019] The second support assembly also includes a second drive member, which is used to drive the second support platform to move radially.

[0020] The measurement assembly also includes a measurement drive unit for driving the measurement stage to move radially.

[0021] In one possible implementation, the jacking assembly further includes a strut and a strut support plate. There are two struts, which are arranged radially, with one end connected to the jacking member and the other end connected to the telescopic end of the telescopic member. The strut support plate is used to support the strut.

[0022] In one possible implementation, the support platform is equipped with a lifting platform, and the telescopic components and strut support plates are respectively installed on the lifting platform.

[0023] In one possible implementation, the measuring element is raised and lowered on the measuring platform.

[0024] Secondly, this application also provides a method for calibrating a ring component, which employs any of the possible ring component calibration fixtures provided in the first aspect for calibration. The method for calibrating the ring component includes:

[0025] Place the ring flat on the first support assembly, the second support assembly, and the measuring assembly, and adjust it so that the center of the ring is at the center of the circle. Then, make the measuring assembly abut against the outer or inner circle of the ring.

[0026] The controller controls the first and second support components to jointly drive the ring to rotate around the center, and the measuring component detects the outer or inner radius of the ring and determines the short axis of the ring.

[0027] The controller controls the first and second support components to rotate the short axis of the ring to be opposite to the push component, and controls the push component to extend to both sides to open the short axis of the ring.

[0028] The ring alignment fixture and method provided in this application include a first support assembly, a second support assembly, a measuring assembly, a pushing assembly, and a controller. When aligning a ring deformed into an ellipse, the first support assembly, the second support assembly, and the measuring assembly jointly support the ring to ensure it lies flat. The first support assembly, the second support assembly, and the measuring assembly form a circle, with the center of this circle serving as a measuring reference. The first and second support assemblies jointly drive the ring to rotate around the center, allowing the measuring assembly to detect the radius of the ring and determine its minor axis. The controller controls the first and second support components to rotate the short axis of the ring to be opposite to the push component, which is the adjustment position of the short axis of the inner push ring. By controlling the push component to extend to both sides, the short axis of the ring is opened up, so that the length of the short axis is basically the same as that of the long axis, which meets the subsequent machining allowance requirements of the ring and completes the correction of the ring. Therefore, after the inspection is completed, the ring can be corrected immediately without moving the ring to different equipment for separate inspection and correction, which simplifies the operation process and ensures the collaborative operation of measuring and correcting the ring.

[0060] The accompanying drawings illustrate specific embodiments of this application, which will be described in more detail below. These drawings and descriptions are not intended to limit the scope of the concept in any way, but rather to illustrate the concept of this application to those skilled in the art through reference to particular embodiments. Detailed Implementation

[0061] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.

[0062] Currently, during the production of large-sized metal rings (i.e., ring-shaped workpieces), both cold and hot working processes can generate certain internal stresses in the rings, causing a certain degree of elliptical deformation. When the deformation exceeds the machining allowance, the metal rings face the risk of being scrapped. Therefore, it is necessary to correct (or round) the metal rings to reduce their deformation and ensure that they meet the requirements of subsequent processing.

[0063] Generally, methods for correcting workpiece deformation can be divided into two types. One is the heat treatment correction method. Commonly used heat treatment correction methods include heating and quenching at Ac1 temperature to shrink expanded deformation workpieces and quenching expansion to expand shrinked deformation workpieces. For large workpieces, this correction method is often time-consuming and labor-intensive, and it will affect the hardness, hardened layer depth, and microstructure of the hot-worked area of ​​the metal ring, resulting in relatively low construction efficiency. The other is the mechanical correction method, which uses mechanical or local heating methods to induce localized micro-plastic deformation in the deformed workpiece, while simultaneously releasing and redistributing residual internal stress to achieve the purpose of deformation correction. Commonly used mechanical correction methods include cold pressing correction, hot pressing correction before quenching and cooling to room temperature, pressure tempering correction, "hot spot" correction using oxy-acetylene flame or high frequency to locally heat the deformed workpiece, and hammering correction. Among these, cold pressing correction achieves the correction effect by applying load to the deformed part of the metal ring using correction equipment. This method has a wide range of applications and high correction efficiency.

[0064] However, the cold-pressing calibration fixtures in related technologies cannot measure the deformation of the rings to be calibrated. Other methods are needed to measure the deformation and record the deformation data to guide the selection of the calibration area. Each calibration requires measurement using other methods, resulting in time and labor costs, and failing to meet the efficient measurement and calibration production needs of rings with large diameter spans. For steel rings with diameters exceeding 5 meters, the large diameter span, especially when heavy, makes them inconvenient to handle, resulting in poor mobility and requiring large lifting equipment for transport, leading to lengthy adjustment times and significant labor costs.

[0065] To address the aforementioned problems encountered when calibrating large ring components, this application provides a calibration fixture for ring components, comprising a first support assembly, a second support assembly, a measuring assembly, a pushing assembly, and a controller. The first support assembly, second support assembly, and measuring assembly form a circle to jointly support the ring component. The first and second support assemblies jointly drive the ring component to rotate around the center of the circle. The measuring assembly detects the radius of the ring component to determine its minor axis. The pushing assembly, located at the center of the circle, extends to both sides to open up the position of the minor axis, ensuring that the lengths of the major and minor axes are substantially consistent. This achieves the purpose of coordinated measurement and calibration of the ring component.

[0066] The technical solution of this application will be described in detail below with reference to the accompanying drawings and several specific embodiments. It is understood that the following embodiments can be combined or used individually.

[0067] like Figures 1-3 As shown, this embodiment provides a ring correction fixture for correcting a ring that has been deformed into an ellipse. The ring correction fixture includes a first support component 100, a second support component 200, a measuring component 300, a pushing component 400, and a controller.

[0068] The first support assembly 100, the second support assembly 200, and the measuring assembly 300 are used to jointly support the deformed ring 10, and the jacking assembly 400 is located at the center of the circle formed by the first support assembly 100, the second support assembly 200, and the measuring assembly 300.

[0069] The first support assembly 100 and the second support assembly 200 jointly drive the ring 10 to rotate around the center. The first support assembly 100, the second support assembly 200, the measuring assembly 300 and the pushing assembly 400 are all electrically connected to the controller. The measuring assembly 300 is used to contact the ring 10 and detect the radius of the ring 10 to determine the short axis of the ring 10. The controller controls the first support assembly 100 and the second support assembly 200 to rotate the position of the short axis of the ring 10 to be opposite to the pushing assembly 400, and controls the pushing assembly 400 to extend to both sides to open the position of the short axis of the ring 10.

[0070] In this embodiment, the first support component 100, the second support component 200, and the measuring component 300 form a circle to support the ring component 10. For example, support rollers can be respectively provided on the first support component 100, the second support component 200, and the measuring component 300, with the axes of the support rollers arranged radially along the circle. A rotary drive driven by a stepper motor is installed on the support rollers on the first support component 100 and the second support component 200. Thus, the rotary drive drives each support roller to rotate synchronously, causing the ring component 10 to rotate around the center. The number of first support components 100 and second support components 200 can be multiple, and they can be evenly distributed around the center. The specific number and position of the first support components 100 and second support components 200 can be set according to actual needs in the actual working conditions; therefore, this embodiment does not impose excessive limitations on this aspect.

[0071] The measuring component 300 is used to detect the radius of the ring 10. By acquiring the radius data of various points on the inner or outer circle of the ring 10, the minor axis of the ring 10 is determined. The measuring component 300 is a displacement detection element, which is radially positioned on the measuring component 300. The probe of the displacement detection element abuts against the inner or outer circle of the ring 10, with the contact point serving as the detection point. The displacement detection element is electrically connected to the controller. Thus, the displacement detection element obtains the radius of the ring 10 by measuring the distance from the detection point to the center of the circle, and transmits this data to the controller.

[0072] For example, the radius R is measured every time the ring 10 rotates by a certain angle, until the ring 10 completes one full rotation, which is one measurement cycle. The angle can be 1°, 2°, 5°, 10°, ... Taking a 1° rotation as an example, the radius measured the first time is R1, the radius measured the second time is R2, ..., and the radius measured the 360th time is R... 360 The minor axis can be determined by comparing the sum of detection radii that differ by 180°. L represents the length of the axis passing through the center of the deformed elliptical ring 10 (including the major and minor axes). x R represents the detection radius of the x-th measurement point. x The detection radius R of the (x+180th)th measurement point x+180 The sum of, i.e., L x =R x +R x+180 Then L1 = R1 + R 181 L2 = R2 + R 182 , ..., L 180 =R 180 +R 360 By comparing the lengths of these 180 axes, the shortest axis L is... x The corresponding point R x R x+180 If the point is 90° away from the minor axis, then the point R is... x+90 R x+270 If the major axis is minimized, such as L30, then R... 30 R 210 The point passes through the minor axis, R 120 R 300 The point passes through the major axis.

[0073] The length ΔL requiring jacking correction is half the length of the major axis minus the minor axis, multiplied by the adjustment factor K, i.e., ΔL = K * ((R) x+90 +R x+270 )-(R x +R x+180 )) / 2, where K is the adjustment coefficient determined by the springback of the ring 10, K>1, and the adjustment coefficient K is selected according to the material of the ring 10.

[0074] The minor axis L is obtained x The corresponding point R x R x+180 After positioning, the ring 10 can be driven to rotate around the center by the first support component 100 and the second support component 200. The rotation angle is the angle between the point and the starting detection point. On one hand, the controller can automatically control the first support component 100 and the second support component 200 to rotate the ring 10 to this angle. On the other hand, the controller can also be used manually to jog the first support component 100 and the second support component 200 to rotate the ring 10 to this angle, so that the detection point R... x The inner circle at the point is aligned with one of the pushing ends of the pushing assembly 400, and correspondingly, the other detection point R... x+180 The inner circle at the point is aligned with another pushing end of the pushing assembly 400 so that the pushing assembly 400 can push outward for correction.

[0075] Continuing with the example of 360 detection points, if L30 is the minor axis, then the first support component 100 and the second support component 200 jointly drive the ring 10 to rotate around the center, with a rotation angle of 30°, so that the detection point R... 30 The inner circle at the point is aligned with one of the pushing ends of the pushing assembly 400, and correspondingly, the other detection point R... 30+180 The inner circle of the ring 10 is aligned with another pushing end of the pushing assembly 400. The pushing assembly 400 is used to push the inner circle of the ring 10. For example, the pushing assembly 400 is located at the center of the circle and has two opposing pushing heads that move toward or away from each other radially along the circle. In this way, when the two pushing heads abut against the inner circle of the ring 10, the short axis position of the ring 10 can be opened by driving the two pushing heads to move away from each other.

[0076] The controller is used to control the first support assembly 100, the second support assembly 200, the measuring assembly 300, and the pushing assembly 400 to perform coordinated actions. For example, the controller can control the first support assembly 100 and the second support assembly 200 to rotate the ring 10 synchronously, the controller can control the measuring assembly 300 to detect the radius data on the inner or outer circle of the ring 10, and the controller can control the pushing assembly 400 to push the inner circle of the ring 10.

[0077] Specifically, when calibrating the ring 10, the ring 10 is placed flat on a testing station formed by the first support assembly 100, the second support assembly 200, and the measuring assembly 300. With the support of the three components, and taking the center of the circle as a reference, the first support assembly 100 and the second support assembly 200 jointly drive the ring 10 to rotate around the center. The measuring assembly 300 detects the radius of the ring 10 to determine the short axis of the ring 10. The controller controls the first support assembly 100 and the second support assembly 200 to rotate the position of the short axis of the ring 10 to be opposite to the push assembly 400, thus adjusting the position of the short axis of the inner push ring 10. By controlling the push assembly 400 to extend to both sides, the position of the short axis of the ring 10 is opened, so that the length of the long axis is basically the same as that of the short axis, which meets the subsequent machining allowance requirements of the ring 10, thereby completing the calibration work of the ring 10.

[0078] It is understandable that, compared to the prior art, which requires relying on other methods or a certain device to measure the ring 10 and then moving it to another device for calibration, in this embodiment, the ring 10 can be calibrated immediately after the detection is completed, without having to move the ring 10 to different devices for separate detection and calibration. This simplifies the operation process and ensures the collaborative operability of measuring and calibrating the ring 10.

[0079] It is worth noting that after the ring 10 is measured and calibrated once, the controller controls the push assembly 400 to return to its original position. The controller then controls the first support assembly 100 and the second support assembly 200 to jointly drive the ring 10 to rotate around the center, and controls the measuring assembly 300 to perform a second measurement on the ring 10. If the deformation of the ring 10 does not meet the turning process requirements (i.e., the difference between the long axis and the short axis is large), the above calibration process can be repeated until the deformation of the ring 10 meets the turning process requirements. All of this is done on the same tooling, and there is no need to transfer the ring 10.

[0080] In one possible design, such as Figure 1 , Figure 3 As shown, the first support assembly 100 includes a first support platform 110 and a first idler roller 120 disposed on the first support platform 110. The first support platform 110 is provided with at least one rotatable first idler roller 120, and the rotation axis of the first idler roller 120 is arranged radially along a circle. Figure 1 The device includes two first rollers 120 arranged side by side. The ends of the first rollers 120 can be connected to a rotary drive mechanism driven by a stepper motor.

[0081] The second support assembly 200 includes a second support platform 210 and a second idler roller 220 disposed on the second support platform 210. The second support platform 210 is provided with at least one rotatable second idler roller 220, and the rotation axis of the second idler roller 220 is arranged radially along a circle. Figure 1 Two second idler rollers 220 are arranged side by side. The ends of the second idler rollers 220 can be connected to a rotary drive transmission driven by a stepper motor. The second idler rollers 220 are the same as the first idler rollers 120 and rotate synchronously, such as... Figure 1 As shown, if the driving force of the first roller 120 on the ring 10 is upward, then the driving force of the second roller 220 on the ring 10 is downward, so that the ring 10 can rotate around the center.

[0082] The measuring assembly 300 includes a measuring table 310, a third roller 320, and a measuring element 330. The third roller 320 and the measuring element 330 are both disposed on the measuring table. The measuring element 330 is used to measure the outer radius or inner radius of the ring 10. The pushing assembly 400 includes a telescopic member 410 and two pushing elements 420 respectively disposed at both ends of the telescopic member 410. The telescopic member 410 is disposed at the center. The pushing elements 420 are used to abut against the inner wall of the ring 10 at the short axis position and push the ring 10 outward.

[0083] The measuring platform 310 is equipped with at least one rotatable third roller 320, the rotation axis of which is arranged radially along the circle. Figure 1 Two parallel third rollers 320 are provided in the middle. The third rollers 320, together with the first roller 120 and the second roller 220, support the ring 10, making the ring 10 more stable when rotating.

[0084] The telescopic component 410 can be a two-way hydraulic cylinder, which is fixedly installed at the center and extends and retracts radially along the circle. The pusher 420 is installed at the telescopic end. The specific shape of the contact surface between the pusher 420 and the ring 10 can be set according to the outer or inner circular surface of the specific ring 10.

[0085] The first support platform 110, the second support platform 210, and the measuring platform 310 form a circle. The first idler roller 120, the second idler roller 220, and the third idler roller 320 jointly support the ring 10. The first idler roller 120 and the second idler roller 220 drive the ring 10 to rotate. The first idler roller 120, the second idler roller 220, the measuring component 330, and the telescopic component 410 are all electrically connected to the controller.

[0086] Furthermore, continue as Figure 1 As shown, the first support assembly 100 and the second support assembly 200 are arranged opposite each other and are located on both sides of the center. In this way, the force of the driving ring 10 is distributed on two points on the diameter of the ring 10, making the rotation more stable.

[0087] Two measuring components 300 are provided, located between the second support component 200 and the first support component 100. The measuring elements 330 are respectively located on the perpendicular lines connecting the first idler roller 120 and the second idler roller 220. This allows for convenient operation, as one measuring component 300 can be used to measure the inner circle of the ring 10, while the other can be used to measure its outer circle. Furthermore, the two measuring components 300 support the ring 10, forming a four-point support system with the first support component 100 and the second support component 200.

[0088] Furthermore, such as Figures 1 to 3 As shown, the first support assembly 100 further includes a first reference roller 130, the second support assembly 200 further includes a second reference roller 230, and the measuring assembly 300 further includes a measuring center roller 340. The first reference roller 130 is erected on the first support platform 110, the second reference roller 230 is erected on the second support platform 210, and the measuring center roller 340 is erected on the measuring platform 310. The first reference roller 130, the second reference roller 230, and the measuring center roller 340 respectively abut against the outer surface of the ring 10. In this way, when the ring 10 is initially placed horizontally, based on the principle of three points determining a circle, the approximate center of the ring 10 can be determined to be consistent with the center of the circle by using the first reference roller 130, the second reference roller 230, and the measuring center roller 340, reducing the difficulty of horizontal placement and adjustment of the ring 10.

[0089] In some embodiments, positioning is achieved by the first reference roller 130, the second reference roller 230, and the measuring center roller 340 contacting the outer circle of the ring 10. In other embodiments, the first reference roller 130 and the second reference roller 230 contact the outer circle of the ring 10, while the measuring center roller 340 contacts the inner circle of the ring 10 for positioning. The specific positioning method can be set according to the actual needs in the actual working conditions, and this embodiment does not impose too many limitations on it.

[0090] It should be noted that the first reference roller 130, the second reference roller 230, and the measuring center roller 340 are only used for the initial positioning of the ring 10. During the subsequent rotation of the ring 10, they do not come into contact with the first reference roller 130, the second reference roller 230, and the measuring center roller 340 to avoid interference with the measurement results.

[0091] In order to accommodate the calibration of rings 10 with different diameters, such as Figures 1-3As shown, the calibration fixture in this embodiment may further include a support platform 500, with a first support platform 110, a second support platform 210, and a measuring platform 310 respectively mounted on the support platform 500 in a radially movable manner along the circle. In this way, the first support platform 110, the second support platform 210, and the measuring platform 310 can move radially along the circle on the support platform 500 to change the size of the enclosed circle, thereby adapting to the calibration of rings 10 with different diameters, resulting in better adaptability.

[0092] For example, a number of guide rails are arranged radially along the circle on the support platform 500. For instance, the first guide rail 111 and the second guide rail 112 are arranged in a cross shape. The first support platform 110 and the second support platform 210 are slidably disposed on opposite sides of the first guide rail 111, and the measuring platform 310 is slidably disposed on the second guide rail 112. Of course, guide rods can also be used instead of guide rails for sliding support.

[0093] Furthermore, continue as Figures 1-3 As shown, the first support assembly 100 may further include a first drive member 140, which is disposed on the support platform 500, connected to the first support table 110, and electrically connected to the controller. The first drive member 140 is used to drive the first support table 110 to move radially along the circle. In this way, the first drive member 140 can drive the first support table 110 to move radially along the circle, thereby achieving automatic adjustment.

[0094] For example, the first driving component 140 can be a motor and a lead screw assembly. The lead screw assembly is arranged radially along a circle and is connected to the first support platform 110 via a lead screw nut. One end of the lead screw is connected to the motor for transmission. Thus, when the motor drives the lead screw to rotate, it can drive the first support platform 110 to move radially along the circle. Of course, the first driving component 140 can also be a telescopic rod (such as an electric push rod, hydraulic cylinder, pneumatic cylinder, etc.), and the telescopic direction of the telescopic rod is along the length direction of the first guide rail 111 (e.g.,...). Figure 3 The telescopic rod is set in either the X+ or X- direction, and its telescopic end is connected to the first support platform 110. In this way, the first support platform 110 can also be driven to move along the length direction of the first guide rail 111.

[0095] The second support assembly 200 may further include a second drive member 240, which is disposed on the support platform 500, connected to the second support table 210, and electrically connected to the controller. The second drive member 240 is used to drive the second support table 210 to move radially along the circle. In this way, the second drive member 240 can drive the second support table 210 to move radially along the circle, thereby achieving automatic adjustment.

[0096] Correspondingly, the second driving component 240 can be a motor and lead screw assembly. The lead screw assembly is arranged radially along the circle and is connected to the second support platform 210 through a lead screw nut. One end of the lead screw is connected to the motor for transmission. In this way, when the motor drives the lead screw to rotate, it can drive the second support platform 210 to move radially along the circle. Of course, the second driving component 240 can also be a telescopic rod (such as an electric push rod, hydraulic cylinder, pneumatic cylinder, etc.), and the telescopic direction of the telescopic rod is along the length direction of the first guide rail 111 (e.g., Figure 3 The telescopic rod is set in either the X+ or X- direction, and its telescopic end is connected to the second support platform 210. This also allows the second support platform 210 to move radially along the circle.

[0097] The measuring assembly 300 may further include a measuring drive unit, which is mounted on the support platform 500, connected to the measuring stage 310, and electrically connected to the controller. The measuring drive unit is used to drive the measuring stage 310 to move radially along the circle. In this way, the measuring stage 310 can be driven to move radially along the circle by the measuring drive unit, thereby achieving automatic adjustment.

[0098] Alternatively, the measuring drive component can be a motor and a lead screw assembly. The lead screw assembly is arranged radially along the circle and is connected to the measuring platform 310 via a lead screw nut. One end of the lead screw is connected to the motor drive. Thus, when the motor drives the lead screw to rotate, it can drive the measuring platform 310 to move radially along the circle. Of course, the measuring drive component can also be a telescopic rod (such as an electric push rod, hydraulic cylinder, pneumatic cylinder, etc.), with the telescopic direction along the length of the second guide rail 112 (e.g.,...). Figure 2 The telescopic rod is set in either the Y+ or Y- direction, and its telescopic end is connected to the measuring stage 310. This also allows the measuring stage 310 to move radially along the circle.

[0099] To compensate for the limited extension stroke of the telescopic member 410 due to the increased diameter of the ring 10, the jacking assembly 400 may further include a support rod 430 and a support rod support plate 440. There are two support rods 430, arranged radially along the circle, with one end connected to the jacking member 420 and the other end connected to the extension end of the telescopic member 410. The support rod support plate 440 supports the support rods 430. With this configuration, when the diameter of the ring 10 changes significantly, the extension stroke of the telescopic member 410 can be kept essentially constant by selecting support rods 430 of different lengths.

[0100] The bottom of the strut support plate 440 is fixed, and the upper end of the strut support plate 440 has an upward-facing limiting groove to accommodate the radial movement of the strut 430. It is worth noting that the specific number and position of the strut support plates 440 can be set according to the actual needs in the actual working conditions. In this embodiment, no further limitations are imposed.

[0101] Furthermore, such as Figure 3 As shown, a lifting platform 510 is provided on the support platform 500, and a telescopic component 410 and a support rod plate 440 are respectively installed on the lifting platform 510. This configuration allows for the adjustment of the ring component 10 at different heights, thus broadening its application range. For example, the support platform 500 has a vertically installed lifting mechanism, the upper end of which is connected to the lifting platform 510. This enables the lifting and lowering movement of the lifting platform 510.

[0102] In order to accommodate the measurement position adjustment of the ring 10 at different heights, such as Figures 1 to 3 As shown, in this embodiment, the calibration fixture has a measuring element 330 that is raised and lowered on the measuring table 310. In other words, the measuring element 330 can be mounted on the measuring table 310 via a lifting mechanism. This allows the measuring element 330 to move along the axis of the circle to adjust its detection position. This accommodates the detection of rings 10 of different thicknesses and avoids any protrusions or pits on the inner or outer circle of the ring 10 affecting the continuity of the measuring element 330's detection.

[0103] This embodiment also provides a method for calibrating a ring component, applied to the calibrating fixture for the ring component provided in any of the above embodiments. The structure of the calibrating fixture for the ring component has been described in detail in the above embodiments and will not be repeated here. Figure 4 As shown, the correction method for this ring component has the following steps:

[0104] Step S101: Place the ring 10 flat on the first support component 100, the second support component 200 and the measuring component 300, adjust it so that the center of the ring 10 is located at the center of the circle, and make the measuring component 300 abut against the outer circle or inner circle of the ring 10.

[0105] Specifically, the ring 10, which is deformed into an ellipse, is placed flat on the inspection station, which is formed by the first support component 100, the second support component 200, and the measuring component 300. With the joint support of the first support component 100, the second support component 200, and the measuring component 300, the ring 10 is translated so that the center of the ring 10 coincides with the center of the circle on the inspection station. The measuring component 300 is then moved to abut against the outer or inner circle of the ring 10, thus completing the preparatory work before inspection.

[0106] Step S102: The controller controls the first support component 100 and the second support component 200 to jointly drive the ring 10 to rotate around the center, and the measuring component 300 detects the outer radius or inner radius of the ring 10 and determines the minor axis of the ring 10.

[0107] Specifically, the controller controls the first support component 100 and the second support component 200 to jointly drive the ring 10 to rotate around the center. During the rotation, the radius of a detection point can be detected every certain angle of rotation until the ring 10 rotates one full circle and completes the radius detection of all points. The short axis can be determined by comparing the sum of the detection radii that are 180° apart. The axis with the smallest sum of radii is the short axis. The two detection points corresponding to this axis pass through the short axis. Then, the point that is 90° apart from this point passes through the long axis. The length that needs to be pushed and corrected is half of the long axis minus the short axis and then multiplied by the adjustment coefficient. The adjustment coefficient is selected according to the material of the ring 10. Through this step, the position of the short axis of the deformable ring 10 and the length of the short axis push and corrected are determined.

[0108] Step S103: Control the first support assembly 100 and the second support assembly 200 to rotate the short axis of the ring 10 to be opposite to the push assembly 400, and control the push assembly 400 to extend to both sides to open the short axis position of the ring 10.

[0109] Specifically, the controller controls the first support component 100 and the second support component 200 to jointly drive the ring component 10 to rotate around the center until the inner circles at the two detection points on the short axis are aligned with the two pushing ends of the pushing component 400. The rotation stops, and the controller then controls the pushing component 400 to push outward, causing the inner circle at the short axis position of the deformable ring component 10 to extend outward. Correspondingly, the inner circle at the long axis position of the deformable ring component 10 retracts inward. In this way, the length of the ring component 10 is finally made to be basically consistent with the length of the short axis and return to the circular shape, thereby achieving the correction.

[0110] After the measurement is completed, the controller controls the push assembly 400 to retract, allowing the calibrated ring 10 to be removed. It is worth noting that after each calibration, a second measurement can be performed to ensure that the deformation of the ring 10 meets the turning process requirements. If it does, the ring 10 is removed for the next process; otherwise, the ring 10 can be calibrated a second, third, or even more times until it meets the turning process requirements.
