The calibrating parts currently used are mainly divided into two categories: one is the precision calibrating parts, which have precise size control, but have complex structures, cumbersome use processes, and low efficiency. In addition, the precision calibrating structural parts are not suitable for heating together with calibrating parts. The other is the simple calibrating parts, which have simple structures and are easy to operate, but the calibrating amount of such calibrating parts is difficult to control, and it is easy to over-calibrate or even damage the structural parts.

[0003] There are also simple internal support type correction parts on the market. By rotating the adjusting part, the support rod can be extended or retracted to adjust the length of the top rod so that the top block can abut against the inner wall of the structural part. However, when the correction part is used for annular structural parts, the correction position of the correction part needs to be repeatedly replaced. The relative position of the correction part is not fixed each time the correction is performed, and the radial dimensions of the annular structure cannot be taken into account at the same time, which will cause further deformation of the structural part and the correction dimensions are not easy to control accurately.

[0022] In the claims, specification and drawings of the present utility model, if the terms "include", "have" and their variations are used, they are intended to mean "including but not limited to".

[0023] The present invention will be further described below in conjunction with the embodiments, but is not limited to the contents of the specification.

[0024] The utility model relates to an internal support type correction component suitable for an annular structure, which comprises a mounting member 10 and a plurality of correction structures 20, wherein the correction structure 20 is arranged between the mounting member 10 and the annular structure 30, the correction structure 20 comprises a support rod 21, a correction part 22 and an adjustment member 23, and the plurality of correction structures 20 are arranged in the same plane, wherein the mounting member 10 is arranged in the central area of ​​the correction component, the connecting end 211 of the support rod 21 is connected to the peripheral side wall of the mounting member 10, and the adjustment end 212 of the support rod 21 extends along the length direction; the correction part 22 and the adjustment end 212 of the support rod 21 are connected through the adjustment member 23 It is connected with a gap and abuts against the inner wall or outer wall of the annular structure 30, forming an extension structure for the support rod 21 to extend outward, the shaping portion 22 has a shaping portion body 222 with the same shape as the abutting surface of the inner wall or outer wall of the structural member 30, and the adjusting member 23 is detachably connected to the adjusting end 212 and the shaping portion 22 respectively; the adjusting member 23 has a telescopic amount between the adjusting end 212 of the support rod 21 and the shaping portion 22 along the length direction of the support rod 21, forming an adjusting end of the support rod 21 at the adjusting end 212 that can extend or shorten the rod length, and the adjusting end links the shaping portion 20 to move closer to or away from the annular structure 30.

[0025] It should be noted that the shaping component is separately arranged, and each component of the shaping component is processed and reused from waste parts in the workshop. Before shaping is required, the shaping structure 20 can be assembled on-site outside the annular structure and then connected to the mounting member 10. Alternatively, the connecting ends 211 of several support rods 21 can be first connected to the mounting member 10, and then the adjusting ends 212 of the support rods 21 and the shaping portion 22 are connected in turn through the adjusting members 22 to assemble into a shaping component, and then the shaping component is placed on the annular structure 30. After shaping is completed, the shaping component can be disassembled and placed separately to avoid damage to the shaping component during transportation or storage. In addition, the shaping component has a hollow structure, that is, there is a fan-shaped gap between adjacent support rods 21 and the shaping portion 22, which can reduce the weight of the shaping component itself on the basis of ensuring the shaping efficiency of the shaping component, thereby facilitating operation.

[0026] In addition, in order to reduce the weight of the correction component itself, the support rod 21 and the connecting rod 221 can also be set as a hollow tubular structure. Furthermore, in order to ensure the adjustment range of the adjustment member 23 along the length direction of the support rod 21, an annular limit groove can be set on the outer peripheral wall of the support rod 21 and the connecting rod 221, and the width of the limit groove can be set according to actual needs. At this time, the external thread is set at the bottom of the annular limit groove, so it can guide the installation of the adjustment member 23, and the groove wall is flush with the outer peripheral wall of the support rod 21 or the connecting rod 221, which is convenient for quickly installing and adjusting the adjustment member 23.

[0027] In this embodiment, the number of the shaping structures 20 can be appropriately increased or decreased according to actual needs. For example, the number of the shaping structures 20 in the present application is 6, and the adjusting member 23 can only adjust the support rod 21 to move toward or away from the shaping portion body 222. At this time, the adjusting member 23 and the connecting rod 221 are fixedly connected, or the adjusting member 23 can also only adjust the distance of the connecting rod 221 relative to the shaping portion body 222, or the adjusting member 23 can simultaneously adjust the support rod 21 and the connecting rod 221. Preferably, the adjusting member 23 can simultaneously adjust the distance of the support rod 21 and the connecting rod 221 relative to the shaping portion body 222. At this time, the support rod 21 and the connecting rod 221 move relative to or away from each other at the same time, which is easy to operate and shortens the adjustment time. Since adjacent adjusting members 23 are independently arranged, any one of the adjusting members 23 can be adjusted as needed. It can be seen that the shaping component of the present application can also calibrate the structural member 30 with a non-circular inner wall, and can ensure the accuracy of calibration, thereby improving the scope of application of the shaping component.

[0028] It can be understood that the adjusting member 23 can be a plurality of groups of mutually cooperating protrusions and bayonet sockets, wherein the protrusions and bayonet sockets are respectively arranged on the support rod 21 and the connecting rod 221, and the adjacent protrusions and bayonet sockets are arranged at equal intervals. At this time, the moving distance between the adjustment shape correction portion and the side wall of the annular structure 30 can be accurately calculated, and the convex points of the protrusions can be pressed to accurately control the telescopic length of the support rod 21. Alternatively, the adjusting member can also be set as a sliding block and a sliding rail that cooperate with each other, or the adjusting member 23 can also be set as a threaded sleeve. Preferably, the adjusting member 23 is set as a hollow sleeve, and correspondingly, the inner side wall of the adjusting member 23 is provided with an internal thread. At this time, the support rod 21 and the connecting rod 221 is correspondingly set to an external thread, and the external thread on the support rod 21 and the external thread on the connecting rod 221 are respectively positive thread and negative thread, that is, the adjusting member 23 is sleeved on the outer periphery of the support rod 21 and the connecting rod 221. At this time, the adjusting member 23 can be rotated to adjust the length of the support rod 21; in addition, in order to facilitate rotation, the cross-sectional shape of the outer peripheral wall of the adjusting member 23 is set to a regular polygon, or a lug protrudes outward from the outer peripheral wall of the adjusting member 23, so that the adjusting member 23 can be quickly rotated along the circumferential direction, reducing the difficulty of rotation, and the length between the support rod 21 and the correction part 22 can be quickly adjusted, thereby realizing the calibration of the deformed structural member 30.

[0029] The mounting member can be set as a columnar structure, or the mounting member can be set as a block structure, or the mounting member can be set as an annular structure. Correspondingly, the mounting member can be placed in the hollow part of the annular structure, and the shape of the inner wall of the structural member 30 is calibrated at this time. Alternatively, the mounting member 10 can also surround the outer periphery of the annular structure 30.

[0030] In one embodiment of the present invention, the mounting member 10 can be configured as a mounting block, which is located at the center of the annular structural member 30, and the mounting block has a certain thickness to ensure that the support rods 21 are radially connected to the outer peripheral wall of the mounting block. The shape of the mounting block can be a regular polygon adapted to the number of support rods 21, or the mounting member 10 can also be a circular ring. Preferably, the mounting block is a regular hexagon, and a mounting hole is provided on the side wall of the mounting block. The support rod 21 and the mounting block can be connected by threads, or the support rod 21 and the mounting block can also be welded as a whole, or can also be connected by snap-on connection. As long as the support rod 21 can be fixed on the mounting member 10, after the installation is completed, the support rod 21 and the correction part 2 2, an adjusting member 23 is provided between the support rod 21 and the shaping portion 22, and the shaping portion body 222 is made close to or away from the side wall of the annular structure 30 by adjusting the distance between the support rod 21 and the shaping portion 22, so as to calibrate the shape of the annular structure 30. During the shaping process, the mounting block of the shaping assembly is firstly placed near the center position of the structure 30, and then the distance between the support rod 21 and the shaping portion 22 is adjusted by the adjusting member 23, so that the shaping portion bodies 222 of the shaping portions 22 arranged opposite to each other can abut against the inner side wall of the structure 30 to form a shaping support effect, and during the supporting process, the support rod 21 and the shaping portion 22 are always located in the same plane, ensuring that the support rod 21 remains stationary relative to the structure 30, thereby ensuring the accuracy of the shaping.

[0031] In order to improve the shaping effect of the shaping part 22 on the structural member 30, it is necessary to place the structural member 30 stably on a horizontal plane, that is, the side surface of the shaping part 22 and the side surface of the structural member 30 are arranged parallel to the horizontal plane. During the shaping process, the surface where the shaping part 22 abuts against the inner wall of the structural member 30 forms a shaping part body 222 with an arc surface, which is consistent with the curvature of the structural member 30. The structural member 30 is arranged in an annular shape, so that the shaping part body 222 just fits on the inner wall of the structural member 30, and the shaping part body 222 has a certain width, that is, the width of the shaping part body 222 is less than or equal to the width of the structural member 30. During the shaping process, as long as one side surface is flush with the end face of the structural member 30, the accuracy of the shaping can be ensured and the efficiency of the shaping can be increased. Moreover, it is easy to judge the fit between the shaping component and the inner side of the structural member 30. The structure is simple, the operation is convenient, and the processing materials are saved.

[0032] In addition, in some embodiments, in order to make the shape correction component applicable to annular structural parts 30 of different diameters, the shape correction part body 222 portion close to the shape correction part 22 can be set to a deformable material. At this time, the deformable material is fixed on the outer peripheral surface of the shape correction part 22. For example, the material of the shape correction part body 222 is one or more of the nickel-titanium-based shape memory alloys. In this way, when the shape correction part body 222 contacts the inner wall of the structural part 30, the shape of the shape correction part body 222 will change by changing the temperature or pressure, so that the shape of the shape correction part body 222 is adapted to the shape of the inner wall or the outer shaft wall of the structural part 30. At this time, the shape correction part body 222 and the annular structural part 30 are in surface-to-surface contact, ensuring that there is no gap when the shape correction part body 222 of the shape correction part 22 abuts against the inner wall or the outer wall of the structural part 30, thereby improving the calibration accuracy of the shape correction component, ensuring that the shape correction component can be applicable to annular structural parts 30 of different diameters, and improving the scope of application of the shape correction component.

[0033] In addition, the shaping portion 22 is configured as a hollow structure, and a through hole is provided on the shaping portion body 222. The shaping portion 22 includes an elastic member 223 and a rolling support member 224, wherein one end of the elastic member 223 is fixedly connected to the inner wall of the shaping portion 22, and the other end of the elastic member 223 is connected to the rolling support member 224 through a fixed bracket, and the fixed bracket is formed into a Y shape. Correspondingly, one end of the fixed bracket is configured as a telescopic hollow tubular structure, which is sleeved on the outer periphery of the elastic member 223, and the other end is composed of two support plates, and the fixed bracket is integrally formed, and the two support plates are respectively arranged on both sides of the rolling support member 224, and are rotatably connected to the rotating shaft of the rolling support member 224, so that the rolling support member 224 has a telescopic amount of movement in the radial direction. After the installation is completed, the elastic member 223 is in a compressed state, and the elastic force of the elastic member 223 makes the rolling support The side of member 224 away from elastic member 223 will pass through the through hole; the shape of the through hole can be rectangular, or it can be circular. Preferably, the through hole is set to be circular, and the inner diameter of the circle is smaller than the diameter of the rolling support member 224, that is, after the installation is completed, part of the rolling support member 224 will protrude from the setting of the shaping part body 222. In the shaping of the shaping component, the shaping component is placed on the inner side of the annular structural member 30. At this time, the outer periphery of the rolling support member 224 may contact the side wall of the structural member 30. Since the outer periphery of the rolling support member 224 is arc-shaped, the contact area between the rolling support member 224 and the structural member 30 is small, which reduces the friction resistance between the rolling support member 224 and the structural member 30, so that the rolling support member 224 can slide in and out of the structural member 30 more easily, reducing the difficulty of operation, and can also reduce.

[0034] The number of rolling supports 224 may correspond one-to-one to the number of the shaping portions 22, or the number of rolling supports 224 may be less than the number of the shaping portions 22. In the present application, each shaping portion 22 is provided with a rolling support 224 to ensure that the shaping assembly can move within the structural member 30 through the rolling support 224, thereby improving operability.

[0035] During the shape correction process, the rolling support member 224 will be subjected to radial pressure from the side wall of the structural member 30, so that the outer peripheral surface of the rolling support member 224 abuts against the side wall of the structural member 30. Therefore, the contact position of the outer peripheral surface of the rolling support member 224 and the inner wall of the structural member 30 can be set flush, thereby increasing the contact area between the rolling support member 224 and the structural member 30, ensuring the shape correction support effect.

[0036] In addition, the shape-correcting portion body 222 has a certain thickness to ensure that the shape-correcting portion body 222 can provide shape-correcting support for the side wall of the structural member 30; and, the shape-correcting portion body 222 is connected to the shape-correcting portion 22 by a hinged manner, which makes it easy to remove the rolling support member 224 from the shape-correcting portion 22, ensuring that the shape-correcting component can be used normally.

[0037] The rolling support member 224 can be configured as a sliding wheel with a shock absorbing function. In this case, the sliding wheel can slide out from the structural member 30 in one direction, for example, the direction is set to the axial direction of the structural member; the rolling support member 224 can also be configured as a ball universal pulley, which can slide out from the structural member 30 in any direction. Preferably, the rolling support member 224 is a sliding wheel with a shock absorbing function, which has a simple structure and can ensure that when it abuts against the annular structural member 30, it can form an effective supporting force on the corresponding position of the structural member 30, thereby ensuring the correction result.

[0038] In some other embodiments, the end of the correction part body 222 facing the annular structure 30 is set to be hemispherical, and the spherical arc surface faces the annular structure 30. At this time, the correction part body 222 and the connecting rod 221 are formed as a whole to form the correction part 22, that is, the correction part 22 is rod-shaped, which can reduce the contact area between the correction part body 222 and the annular structure 30. Therefore, for annular structures 30 of different diameters, the contact between the annular structure 30 and the correction part body is equivalent to point-to-point contact, which reduces the influence of the shape of the correction part body 222. In addition, the diameter of the contact part between the correction part 22 and the adjusting member 23 is equal to the diameter of the adjusting end 212 of the support rod 21. By adjusting the telescopic amount between the adjusting end 212 and the correction part body 222 by the adjusting member 23, multi-point simultaneous calibration of the annular structure 30 can be achieved, and it can adapt to annular structures 30 of different diameters, thereby improving the scope of application.

[0039] In order to be able to adjust the gap between the shaping part body 222 of the shaping part 22 and the side wall of the structural member 30, the adjusting end 212 is connected to the shaping part 22 through the adjusting part 23. At this time, the shaping part 22 is formed as an extension structure of the support rod 21. In order to ensure that the shaping component can shape multiple positions of the structural member 30 at the same time, and the number of adjusting parts 23 of the shaping part 22 and the support rod 21 is equal, for example, the shaping part 22 can be three, the shaping part 22 can be four, or the shaping part 22 can also be six, or the shaping part 22 can also be seven. Preferably, the number of the shaping parts 22 is set to six, and the six shaping parts 22 are evenly spaced. A connecting rod 221 is provided at the connection position between each shaping portion 22 and the corresponding adjusting member 23. At this time, the connecting rod 221 has the same diameter as the support rod 21. In addition, in order to more conveniently connect the shaping portion main body 222 with the connecting rod 221, a boss is provided on the shaping portion 22 facing the connecting rod 221. The boss and the shaping portion main body 222 are integrally formed. In addition, a mounting hole is opened at the position of the boss. At this time, the mounting hole has a guiding installation function. Preferably, an internal thread is provided on the inner side wall of the mounting hole, and an external thread is provided on the outer peripheral wall of the connecting rod 221 accordingly. This can ensure that the connecting rod 221 is stably connected to the shaping portion main body 222 and is easy to disassemble.

[0040] The above-mentioned structural member 30 is arranged to be annular. Of course, the shaping component in the present application can also be used to shape the tubular structural member 30, that is, the extension length of the structural member 30 in the axial direction is much greater than the width of the shaping component. At this time, before the shaping component is placed on the inner wall of the component for calibration, it is first necessary to ensure that the supporting force formed by each shaping part 22 on the inner wall of the structural member 30 is distributed radially. Therefore, an angle adjustment member is protruding on the side of the shaping part 22, which has the ability to detect the contact angle between the shaping part 22 and the structural member 30 and drive the shaping part 22 to fine-tune the activity along the axial direction of the structural member 30 according to the contact angle, thereby forming an adjustment structure in which the shaping part body 222 abuts against the inner wall or outer wall of the structural member 30.

[0041] In detail, Figure 2As shown, after the structural member 30 is placed stably, a traction structure 40 is installed on the side of the shape-correcting portion 22. The traction structure can correspond to the number of shape-correcting portions one by one, or the number of traction structures can be less than the number of shape-correcting portions. The traction structure 40 includes a traction rope and a traction block. The traction rope is fixedly connected to the side of the shape-correcting portion 22. Correspondingly, the traction block is slidably connected to the side of the mounting member 10 on the same side of the traction rope. The connecting lines of the fixing points of the multiple traction ropes and the shape-correcting portion 22 form a circle. The other end of each traction rope is connected to the traction rope. The guide blocks are connected. After assembly, the angles between adjacent traction ropes are the same, and the lengths of each traction rope are the same. The traction block has a sliding amount from the inside to the outside along the axial direction of the structural member, which can ensure that each shaping portion 22 is subjected to equal traction force. After the shaping is completed, the operator can pull the traction block to drive the shaping portion 22 to move synchronously toward the axial centerline, so that the shaping component forms an umbrella-shaped structure. At this time, the shaping component is easy to fall off from the structural member. After falling off, the position of the traction block can be restored to the initial position for continued use next time.

[0042] In another embodiment of the present invention, the mounting member 10 may also be a mounting ring, and the outer side wall of the annular structure member 30 needs to be calibrated, that is, the annular structure member 30 is placed at the center of the circle formed by the mounting ring, and a radial support rod 21 is installed on the inner side wall of the mounting ring, and the support rod 21 is extended toward the center of the mounting ring. An adjustment member 23 is installed at the inner end of the support rod 21, and the adjustment member 23 is connected to the calibrated portion 22 having a connecting rod 221. At this time, the inner side wall of the calibrated portion 22 is surrounded by The shape is adapted to the shape of the outer wall of the structural member 30, the number of the correction parts 22 can be adaptively increased according to actual needs, and the adjustment part 23 can adjust the distance between the support rod 21 and the correction part 22 as needed to ensure that the correction part body 222 is completely in contact with the outer wall of the annular structure 30 and generates a radial extrusion force on the annular structure 30 to achieve calibration of the annular structure 30. Therefore, the present application is also applicable to the outer peripheral wall of the correction annular structure 30, which increases the scope of application of the correction component.

[0043] Obviously, the above-mentioned embodiments of the present invention are merely examples for clearly explaining the present invention, and are not intended to limit the embodiments of the present invention. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description. It is impossible to list all the embodiments here. All obvious changes or modifications derived from the technical solution of the present invention are still within the scope of protection of the present invention.
