Description

Technical Field

[0001] This application relates to component calibration equipment, and more particularly to a ring component cold calibration device. Background Technology

[0002] During the production of ring components, both cold and hot working processes generate internal stress, leading to elliptical deformation after machining. If the deformation exceeds the requirements of the machining process, the ring needs to be corrected to bring the deformation within the specified range. Currently, ring correction can be performed using heat treatment or cold treatment. Heat treatment correction is not only time-consuming and labor-intensive but also affects the hardness, hardened layer depth, and microstructure of the hot-worked area. Cold treatment correction uses cold correction equipment to apply load to the deformed area of ​​the ring to achieve the correction purpose.

[0003] In the prior art, the cold alignment equipment for the ring includes a loading roller and two drive rollers. The loading roller and the two drive rollers are distributed in an isosceles triangle so that the ring can be placed between the loading roller and the two drive rollers. The two drive rollers can rotate to drive the ring to rotate around its own axis. The loading roller can apply pressure to the ring downward through a hydraulic or mechanical structure so that the ring is aligned during rotation.

[0004] However, the ring is positioned between the loading roller and the two drive rollers. During the correction process, the loading roller moves, causing the relative positions of the loading roller and the two drive rollers to change. Therefore, the positioning accuracy of the ring is low, resulting in poor correction effect. Summary of the Invention

[0005] This application provides a ring cold calibration device to solve the problems of low positioning accuracy and poor calibration effect of existing cold calibration equipment for rings.

[0006] This application provides a ring cold calibration device, including a base, a positioning component, a calibration component, and a measuring component. The measuring component is disposed on the base and is used to detect the contour shape of the ring. The positioning component includes a drive roller and a positioning roller, both of which are rotatably disposed on the base. The axis of the drive roller is perpendicular to the axis of the positioning roller. At least three positioning rollers are provided and spaced apart circumferentially along the ring. The positioning rollers abut against the radial side of the ring, and the drive rollers abut against the axial end face of the ring, allowing the ring to rotate around its own axis on the base. The calibration component includes a first calibration head, a second calibration head, and a driver. The first and second calibration heads are spaced apart on the base and form a calibration cavity for placing a portion of the ring. At least one of the first and second calibration heads is connected to the driver, which drives at least one of the first and second calibration heads to move toward the calibration cavity.

[0007] In some embodiments, the positioning assembly further includes a first mounting base rotatably connected to the base, the rotation axis of the first mounting base being parallel to the axis of the positioning roller, and the drive roller being rotatably connected to the first mounting base.

[0008] In some embodiments, the first mounting base is provided with a mounting bracket that can slide along the axial direction of the drive roller, and the positioning roller is mounted on the mounting bracket.

[0009] In some embodiments, at least two first mounting bases are provided, with the two first mounting bases respectively disposed on both sides of the correction component.

[0010] In some embodiments, the positioning assembly further includes a second mounting base slidably connected to the base, and at least one of the positioning rollers is disposed on the second mounting base.

[0011] In some embodiments, the first correction head has a first correction arc surface at one end facing the correction cavity, and the second correction head has a second correction arc surface at one end facing the correction cavity. The diameter of one of the first correction arc surface and the second correction arc surface is the same as the outer diameter of the ring, and the diameter of the other is the same as the inner diameter of the ring.

[0012] In some embodiments, the first calibration head is detachably connected to the base, and the second calibration head is detachably connected to the driver.

[0013] In some embodiments, there are two first correction heads, which are spaced apart along a direction perpendicular to the movement of the second correction head, and the second correction head is positioned toward the gap between the two first correction heads.

[0014] In some embodiments, the measuring assembly includes a third mounting base, a column, and a measuring device. The third mounting base is connected to the base, the column is fixed to the third mounting base, and a slider is provided on the column. The slider is movable on the column along the axial direction of the positioning roller, and the measuring device is disposed on the slider.

[0015] In some embodiments, a support assembly is also included, the support assembly comprising a connecting rod, a fixed base, and a support roller; one end of the connecting rod is rotatably connected to the base, the rotation axis of the connecting rod is parallel to the axis of the positioning roller, the fixed base is connected to the other end of the connecting rod, the support roller is rotatably connected to the fixed base, the axis of the support roller is perpendicular to the axis of the positioning roller, and the support roller and the drive roller are in the same plane.

[0016] The ring cold alignment device provided in this application can accurately position the ring on the base through at least three non-collinear positioning rollers, and drive the ring to rotate around its own axis on the base by rotating the driving rollers. During the rotation of the ring, the contour shape of the environment is measured by the measuring component to obtain the deformation of each part of the ring.

[0017] The deformed part of the ring is then moved into the correction cavity. The driver moves the first correction head and / or the second correction head toward the correction cavity and applies pressure to the part of the ring in the correction cavity to correct the deformed part of the ring. After the ring is corrected, the ring continues to rotate and the outer contour shape of the ring after correction is measured by the measuring component. If there are still parts whose deformation exceeds the process requirements, they can continue to be moved into the correction cavity for correction until the ring meets the process requirements.

[0018] During the calibration process, the position of the positioning roller is fixed, which ensures the positioning accuracy of the ring. The first calibration head and the second calibration head calibrate the deformed parts of the ring. Compared with applying pressure to the entire ring for calibration, this improves the calibration effect of the ring. Furthermore, the ring can be repeatedly measured and calibrated without removing it, which also speeds up the calibration efficiency of the ring. Attached Figure Description

[0032] 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

[0033] 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.

[0034] As described in the background section, the cold alignment equipment for rings includes a loading roller and two drive rollers. The two drive rollers are arranged side by side, with the loading roller positioned above them in an isosceles triangle configuration. During ring alignment, the ring is placed between the loading roller and the two drive rollers, so that the outer wall of the ring abuts against the surfaces of the loading roller and drive rollers, thus positioning the ring. The rotation of the drive rollers causes the ring to rotate around its own axis, while the loading roller applies downward pressure to the ring, reducing its elliptical deformation and achieving the alignment purpose. However, because the relative positions of the drive roller and the loading roller change during the alignment process, the positioning position of the ring also changes, resulting in low positioning accuracy and poor alignment effect.

[0035] To address the aforementioned technical problems, this application provides a ring cold calibration device, which can improve the positioning accuracy of the ring during the calibration process, thereby improving the calibration effect of the ring.

[0036] The technical solution of this application and how the technical solution of this application solves the above-mentioned technical problems will be described in detail below with reference to the accompanying drawings and specific embodiments. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments.

[0037] Combination Figures 1-5 As shown, the ring cold calibration device provided in this application embodiment includes a base 100 and a positioning component 200, a calibration component 300 and a measuring component 400 disposed on the base 100. The measuring component 400 is used to detect the contour shape of the ring 600.

[0038] The positioning assembly 200 includes a drive roller 210 and a positioning roller 220, both of which are rotatably mounted on the base 100. The axis of the drive roller 210 is perpendicular to the axis of the positioning roller 220. At least three positioning rollers 220 are provided and spaced apart circumferentially along the ring 600. The positioning rollers 220 are used to abut against the radial side of the ring 600, and the drive rollers 210 are used to abut against the axial end face of the ring 600, so that the ring 600 can rotate around its own axis on the base 100.

[0039] The calibration assembly 300 includes a first calibration head 310, a second calibration head 320, and a driver 330. The first calibration head 310 and the second calibration head 320 are spaced apart on the base 100 and form a calibration cavity 301 for placing a portion of the ring 600. At least one of the first calibration head 310 and the second calibration head 320 is connected to the driver 330, and the driver 330 drives at least one of the first calibration head 310 and the second calibration head 320 to move toward the calibration cavity 301.

[0040] When calibrating the ring 600, the ring 600 is first placed on the drive roller 210, so that the drive roller 210 abuts against the axial end face of the ring 600, and at least three positioning rollers 220 simultaneously abut against the inner or outer wall of the ring 600, so that the position of the ring 600 is positioned by at least three positioning rollers 220, and part of the ring 600 is within the calibration period. The rotation of the drive roller 210 drives the ring 600 to rotate around its own axis on the base 100, and during the rotation of the ring 600, the contour shape of the ring 600 is detected by the measuring component 400 to obtain the part of the ring 600 with a large deformation. Then, the portion of the ring 600 with the largest deformation is moved into the correction cavity 301. The driver 330 is used to drive the first correction head 310 and / or the second correction head 320 to move towards the correction cavity 301. The first correction head 310 and the second correction head 320 simultaneously apply pressure to the portion of the ring 600 that is in the correction cavity 301, so as to achieve the purpose of correcting the deformed portion of the ring 600.

[0041] Understandably, during the calibration of the ring 600, at least three positioning rollers 220 maintain precise positioning of the ring 600, and the first calibration head 310 and the second calibration head 320 calibrate parts of the ring 600 to improve the calibration effect. Furthermore, after calibration of the ring 600, it can continue to rotate, and the measuring component 400 can be used to measure the calibrated dimensions of the ring 600 again. If there are still areas with significant deformation, the calibration operation can continue, eliminating the need to repeatedly remove the ring 600 from the cold calibration device, thus improving the calibration efficiency of the ring 600.

[0042] Specifically, the base 100 can be welded from steel profiles to provide stable support for the positioning component 200, the calibration component 300, and the measuring component 400. The specific shape of the base 100 can be adapted to the structure of the positioning component 200, the calibration component 300, and the measuring component 400. For example, the base 100 includes a first base 110 and a second base 120, both of which are rectangular structures. The second base 120 is fixed to one end of the first base 110.

[0043] The axis of the drive roller 210 can be arranged horizontally. The drive roller 210 can be disposed on the first base 110 or the second base 120. There can be one or more drive rollers 210, and when there are multiple drive rollers 210, the drive rollers 210 should be arranged in a circular pattern on the base 100. For example, there are two drive rollers 210, which are spaced apart on the first base 110. The correction component 300 is also disposed on the first base 110 and located between the two drive rollers 210.

[0044] When calibrating the ring 600, the ring 600 is placed vertically on the drive roller 210 with its axis in place. The lower end face of the ring 600 is in contact with the surface of the drive roller 210, so that the rotation of the drive roller 210 can drive the ring 600 to rotate around its own axis. It is worth mentioning that the rotation of the ring 600 can be manually controlled, that is, the operator can manually control the rotation of the drive roller 210 or directly manually control the rotation of the ring 600. The rotation of the ring 600 can also be automatically operated. For example, a drive motor can be installed on the base 100 and connected to the drive roller 210. The drive motor can drive the drive roller 210 to rotate automatically, so as to achieve the purpose of automatically controlling the rotation of the ring 600.

[0045] The positioning rollers 220 have their axes arranged vertically. There are at least three positioning rollers 220, and the projection points of their axes on the same horizontal plane are not on the same straight line, allowing the ring 600 to be positioned using at least three positioning rollers 220. In use, the positioning rollers 220 can be all positioned inside the ring 600, i.e., abutting against the radial inner surface of the ring 600, or they can be all positioned outside the ring 600, i.e., abutting against the radial outer surface of the ring 600. Both configurations achieve the positioning purpose of the ring 600.

[0046] The specific number of positioning rollers 220 and their distribution on the base 100 can be adapted to actual needs. For example, there are three positioning rollers 220, including two first positioning rollers 220a and one second positioning roller 220b. The two first positioning rollers 220a are spaced apart on the first base 110 and are located at the two drive rollers 210 respectively. The second positioning roller 220b is located on the second base 120 and is located on the perpendicular bisector of the line connecting the two first positioning rollers 220a.

[0047] In some embodiments, the positioning assembly 200 further includes a first mounting base 230 rotatably connected to the base 100, the rotation axis of the first mounting base 230 being parallel to the axis of the positioning roller 220, and the drive roller 210 being rotatably connected to the first mounting base 230.

[0048] Specifically, such as Figure 3 As shown, the first mounting base 230 can be circular. The first mounting base 230 is located on the top surface of the first base 110, and the bottom of the first mounting base 230 can be provided with a rotating shaft (not shown in the figure). The axis of the rotating shaft is parallel to the axis of the positioning roller 220. The rotating shaft is rotatably connected to the first base 110, so that the first mounting base 230 can rotate around the axis of the rotating shaft. The driving roller 210 is rotatably disposed on the first mounting base 230, and the axis of the driving roller 210 can be arranged radially along the first mounting base 230.

[0049] Of course, the first mounting base 230 can also be elliptical, rectangular or other irregular shapes. The rotational connection between the first mounting base 230 and the base 100 can also be achieved by nesting connection, slide rail 231 or slide groove connection, etc. This embodiment does not impose specific restrictions on this.

[0050] By rotating the first mounting base 230 on the base 100, the axial direction of the drive roller 210 can be adjusted. When calibrating rings 600 of different sizes, the axis of the drive roller 210 can be made to intersect with the axis of the ring 600 after it is positioned by the positioning roller 220 by rotating the first mounting base 230. This causes the drive roller 210 to generate a tangential driving force on the ring 600 when it rotates, thus preventing the ring 600 from deviating from its rotation direction and improving the stability and accuracy of the ring 600 during rotation.

[0051] Furthermore, in some embodiments, the first mounting base 230 is provided with a mounting bracket 240 that can slide along the axial direction of the drive roller 210, and a positioning roller 220 is provided on the mounting bracket 240.

[0052] Specifically, the first mounting base 230 may be provided with two parallel slide rails 231, which are parallel to the axial direction of the drive roller 210. The two slide rails 231 are located on both sides of the drive roller 210. The mounting bracket 240 may include a crossbar and vertical bars connected to both ends of the crossbar. The crossbar is located above the drive roller 210, and the two vertical bars are located on both sides of the drive roller 210. The bottom ends of the two vertical bars are connected to the two slide rails 231, so that the mounting bracket 240 can slide along the axial direction of the drive roller 210 on the first mounting base 230 without interfering with the rotation of the drive roller 210 or its contact with the ring 600. A first positioning roller 220a may be provided at the top of the crossbar. The thickness of both the crossbar and the vertical bars should be less than the diameter of the first positioning roller 220a to avoid interfering with the contact between the first positioning roller 220a and the ring 600.

[0053] Of course, the mounting bracket 240 can also adopt other shapes, and the sliding connection between the mounting bracket 240 and the first mounting base 230 can also be achieved through a groove structure or a pulley structure, which will not be described in detail in this embodiment.

[0054] By sliding the mounting bracket 240 on the first mounting base 230, the relative position of the first positioning roller 220a and the drive roller 210 can be adjusted. When calibrating rings 600 of different sizes, the position of the first positioning roller 220a can be changed so that after the inner wall of the ring 600 abuts against the first positioning roller 220a, part of the ring 600 can be accurately placed in the calibration cavity 301. Combined with the adjustment of the axis orientation of the drive roller 210, more accurate position adjustment can be made for rings 600 of different sizes, improving the accuracy of ring positioning.

[0055] It is understood that the number of first mounting seats 230 should be consistent with the number of drive rollers 210. For example, when there are two drive rollers 210, there are also two first mounting seats 230. The two first mounting seats 230 are respectively arranged on both sides of the correction assembly 300, so that the two drive rollers 210 and the two first positioning rollers 220a can be respectively arranged on the two first mounting seats 230.

[0056] In some embodiments, the positioning component 200 further includes a second mounting base 250, which is slidably connected to the base 100, and at least one positioning roller 220 is provided on the second mounting base 250.

[0057] Specifically, such as Figure 4As shown, the second mounting base 250 can be configured as a rectangular structure. The second mounting base 250 can be disposed on the second base 120. The second base 120 can be provided with two parallel tracks 121. The direction of the tracks 121 can be set perpendicular to the direction of the line connecting the two first positioning rollers 220a. The bottom of the second mounting base 250 is connected to the two tracks 121, so that the second mounting base 250 can slide on the second base 120.

[0058] Of course, the second mounting base 250 can also be set to a circular, elliptical or other irregular shape. The sliding connection between the second mounting base 250 and the second base 120 can also be achieved by a sliding groove structure or a pulley structure, etc. In this embodiment, they will not be listed in detail.

[0059] The second positioning roller 220b can be mounted on the second mounting base 250. It is understood that the second positioning roller 220b is located on the perpendicular bisector of the line connecting the two first positioning rollers 220a. When the second mounting base 250 moves, the second positioning roller 220b will move along the perpendicular bisector of the line connecting the two first positioning rollers 220a to change the relative position of the three positioning rollers 220. This can change the diameter of the ring 600 that the three positioning rollers 220 can position, so that more sizes of rings 600 can be positioned and corrected, thus improving the applicability of the cold calibration device.

[0060] Furthermore, when fixing the ring 600, the second mounting base 250 can be moved towards the first mounting base 230 first, so that the inner wall of the ring 600 abuts against the two first positioning rollers 220a. Then, the second mounting base 250 drives the second positioning roller 220b to move away from the first mounting base 230, so that the second positioning roller 220b also abuts against the inner wall of the ring 600. Thus, the ring 600 can be positioned on the base 100 by the three positioning rollers 220, which facilitates the fixing and removal of the ring 600.

[0061] It is worth mentioning that the sliding of the second mounting base 250 can be manually controlled, that is, the operator can manually control the movement of the second mounting base 250 and the second positioning roller 220b; the slider 421 of the second mounting base 250 can also be automatically controlled. For example, a drive assembly (not shown in the figure) can be provided on the second base 120. The drive assembly can be a lead screw slider 421 mechanism, a hydraulic mechanism, or a pneumatic mechanism. The drive assembly is connected to the second mounting base 250, and the automatic sliding of the second mounting base 250 can be controlled by the drive assembly. This embodiment does not impose specific limitations on this, and can be adapted according to actual needs.

[0062] After the ring 600 is positioned on the base 100 by the three positioning rollers 220, a portion of the ring 600 is located within the correction cavity 301 formed between the first correction head 310 and the second correction head 320. The driver 330 drives the first correction head 310 and the second correction head 320 to move relative to each other, applying pressure to the portion of the ring 600 within the correction cavity 301, thereby reducing the deformation of the ring 600. It is understood that the first correction head 310 and the second correction head 320 should be located on the inner and outer sides of the ring body, respectively. For example, after the ring 600 is positioned, the second correction head 320 is located on the inner side of the ring 600, and the first correction head 310 is located on the outer side of the ring 600.

[0063] The actuator 330 can be a hydraulic cylinder, a pneumatic cylinder, or a lead screw and slider mechanism 421, etc., and no specific limitation is made in this embodiment. The actuator 330 can drive only the first correction head 310 or the second correction head 320 to move, or the actuator 330 can drive the first correction head 310 and the second correction head 320 to move simultaneously, all of which can achieve the purpose of applying pressure to the ring 600 for correction. For example, the base 100 also includes a first fixed bracket 130 and a second fixed bracket 140, both of which are made of welded steel plates. The first fixed bracket 130 and the second fixed bracket 140 are spaced apart on the first base 110. The first correction head 310 is connected to the first fixed bracket 130, the actuator 330 is connected to the second fixed bracket 140, and the second correction head 320 is connected to the actuator 330.

[0064] Furthermore, in some embodiments, the first correction head 310 has a first correction arc surface 311 at one end facing the correction cavity 301, and the second correction head 320 has a second correction arc surface 321 at one end facing the correction cavity 301. The diameter of one of the first correction arc surface 311 and the second correction arc surface 321 is the same as the outer diameter of the ring 600, and the diameter of the other is the same as the inner diameter of the ring 600.

[0065] like Figure 5 As shown, when the first correction head 310 is on the outside of the ring 600, the diameter of the first correction arc surface 311 should be consistent with the outer diameter of the ring 600. When the second correction head 320 is on the inside of the ring 600, the diameter of the second correction arc surface 321 should be consistent with the inner diameter of the ring 600. This ensures that the first correction head 310 and the second correction head 320 can fully fit and contact the outer and inner walls of the ring 600, limiting the amount of correction deformation of the ring 600 during correction and preventing the ring 600 from failing to correct due to excessive correction deformation.

[0066] Of course, when the first correction head 310 and the second correction head 320 are located on the inner and outer sides of the ring 600 respectively, the first correction arc surface 311 and the second correction arc surface 321 correspond to the inner and outer wall dimensions of the ring 600 respectively. In this embodiment, they will not be listed and described in detail.

[0067] It is understood that when calibrating rings 600 of different sizes, the dimensions of the first calibration arc surface 311 and the second calibration arc surface 321 should be adapted to the different sizes of rings 600. Therefore, in some embodiments, the first calibration head 310 is detachably connected to the first fixed bracket 130, and the second calibration head 320 is detachably connected to the driver 330, so that the first calibration head 310 and the second calibration head 320 of the appropriate size can be replaced for rings 600 of different sizes, thereby improving the applicability of the cold calibration device.

[0068] In this embodiment, the first calibration head 310 and the first fixed bracket 130, and the second calibration head 320 and the driver 330 can be detachably connected by means of snap-fit, plug-in or bolt fastener connection. No specific restrictions are made, and the configuration can be adapted according to the actual structure.

[0069] In some embodiments, combined with Figure 1 , Figure 2 and Figure 5 As shown, there may be two first correction heads 310, which are distributed at intervals along the direction perpendicular to the movement of the second correction head 320, and the second correction head 320 is positioned toward the gap between the two first correction heads 310.

[0070] That is, the two first correction heads 310 and the second correction head 320 are staggered to provide space for the deformation of the ring 600 during correction and to make the pressure on the ring 600 greater, thereby further improving the correction effect on the ring 600.

[0071] Of course, two second correction heads 320 can also be provided and spaced apart, and one first correction head 310 can be provided and facing the gap between the two second correction heads 320. The driver 330 is connected to the two second correction heads 320 and drives the two second correction heads 320 to move simultaneously toward the direction of the first correction head 310, which can also achieve the purpose of better correction of the ring body.

[0072] In some embodiments, the measuring assembly 400 includes a third mounting base 410, a column 420, and a measuring device 430. The third mounting base 410 is connected to the base 100, the column 420 is fixed to the third mounting base 410, and a slider 421 is provided on the column 420. The slider 421 can move along the axial direction of the positioning roller 220 on the column 420, and the measuring device 430 is disposed on the slider 421.

[0073] Specifically, such asFigure 4 As shown, the third mounting base 410 can be rectangular, and the column 420 is vertically mounted on the top surface of the third mounting base 410. The slider 421 can be connected to the column 420 by a structure such as a groove or pulley, allowing the slider 421 to slide vertically on the column 420. The measuring device 430 can be a laser sensor or a distance sensor. After the ring 600 is positioned on the base 100, the measuring device 400 is located on the outside of the ring 600, that is, the measuring device 430 faces the outer surface of the ring 600. During the rotation of the ring, the measuring device 430 obtains the distance between itself and the outer surface of the ring, so as to determine the deformation of various parts of the ring by the change in distance. Furthermore, the height of the measuring device 430 can be adjusted by sliding the slider 421 on the column 420. The height of the measuring device 430 can be adjusted for rings 600 with different axial thicknesses, so that the measuring device 430 can accurately face the surface of the ring 600.

[0074] Of course, the third mounting base 410 can also be of other shapes, and the measuring component 400 can also be set inside the ring 600, with the measuring instrument 430 facing the inner side of the ring 600. Similarly, the deformation of each part of the ring can be determined by measuring the change in the distance from the inner side.

[0075] It is worth mentioning that the third mounting base 410 can be fixed on the second base 120, or it can be connected to the rail 121 set on the second base 120 so that the third mounting base can also slide on the second base 120 to adjust the initial distance between the measuring device 430 and the ring 600.

[0076] In some embodiments, the ring 600 cold calibration device may further include a support assembly 500, which includes a connecting rod 510, a fixed seat 520, and a support roller 530. One end of the connecting rod 510 is movably connected to the base 100, and the rotation axis of the connecting rod 510 is parallel to the axis of the positioning roller 220. The fixed seat 520 is connected to the other end of the connecting rod 510, and the support roller 530 is rotatably connected to the fixed seat 520. The axis of the support roller 530 is perpendicular to the axis of the positioning roller 220, and the support roller 530 and the drive roller 210 are on the same plane.

[0077] Specifically, the connecting rod 510 is made of welded steel plate or directly uses steel profiles of corresponding length. One end of the connecting rod 510 can be connected to the first base 110 or the second base 120. For example, the first base 110 has a connecting shaft on its side, and the axis of the connecting shaft is vertically set. One end of the connecting rod 510 is rotatably connected to the connecting shaft, so that the connecting rod 510 can rotate relative to the first base 110. The fixed seat 520 can be rectangular and can be fixed to the end of the connecting rod 510 away from the rotating shaft by welding or bolt connection. The axis of the support roller 530 is also set horizontally, and the top height of the support roller 530 should be on the same horizontal plane as the top height of the drive roller 210.

[0078] The bottom end face of the ring 600 can simultaneously abut against the drive roller 210 and the support roller 530, so that the support roller 530 can increase the support point for the bottom of the ring 600, improve the stability of the ring 600 on the base 100, and the position of the support roller 530 can be adjusted by the relative rotation of the connecting rod 510 and the base 100, so that the support roller 530 can be used for rings 600 of various sizes.

[0079] Of course, the connecting rod 510 and the base 100 can also be detachably connected by a snap-fit ​​or plug-in structure. The position of the support roller 530 can be adjusted by fixing the connecting rod 510 at different positions on the base 100. In this embodiment, these will not be listed in detail.

[0080] It is worth mentioning that the number of support components 500 can be set to multiple, such as Figure 1 and Figure 2 As shown, four support components 500 are provided and respectively arranged around the base 100, so that the four support components 500 can be used to support each part of the ring 600 at the same time, thereby further improving the positional stability of the ring 600 during rotation or correction.

[0081] In summary, the cold-calibration device for the ring 600 in this embodiment of the application can accurately position the ring 600 on the base 100 using at least three positioning rollers 220, and make the ring 600 abut against the drive roller 210. The drive roller 210 can drive the ring 600 to rotate around its own axis, so that the contour shape of the ring 600 can be measured by the measuring component 400 to obtain the deformation of each part of the ring 600. Then, by moving the part of the ring 600 with a large deformation into the calibration cavity 301, the relative movement of the first calibration head 310 and the second calibration head 320 applies pressure to the part of the ring 600 with a large deformation, thereby achieving the purpose of calibrating the ring 600.

[0082] Furthermore, the orientation of the drive roller 210 axis can be adjusted by rotating the first mounting base 230, the relative position of the first positioning roller 220a and the drive roller 210 can be adjusted by sliding the mounting bracket 240 on the first mounting base 230, and the position of the second positioning roller 220b can be adjusted by sliding the second mounting base 250. The first calibration head 310 and the second calibration head 320 can be replaced according to the different sizes of the ring 600. The measuring device 430 in the measuring assembly 400 can also adjust its height according to the different thicknesses of the ring 600, so that the cold calibration device for the ring 600 can be applied to rings 600 of various sizes, with a wide range of applications and high practicality.
