It should be noted that the concepts such as "first" and "second" mentioned in the present invention are only used to distinguish different devices, modules or units, and are not used to limit the order or mutual dependence relationship of the functions performed by these devices, modules or units

[0029] It should be noted that the modifiers "one" and "more than one" mentioned in the present invention are illustrative rather than restrictive. Those skilled in the art should understand that, unless otherwise clearly specified in the context, it should be understood as "one or more".

[0030] As Figures 1 to 5 shown, the present invention provides a device for circularity correction and deformation prevention of a cylinder body, including a receiving member 10; a plurality of adjusting components (20), the plurality of adjusting components (20) are circumferentially distributed along the receiving member (10), and each adjusting component 20 includes a support member 21, a first adjusting member 22 and a second adjusting member 23. The first adjusting member 22 and the second adjusting member 23 are both arranged on the receiving member 10. The support member 21 has a connecting portion arranged close to the middle of the receiving member 10 and a supporting portion arranged away from the middle of the receiving member 10. The supporting portion is used for abutting against the inner wall of the cylinder body. The first adjusting member 22 and the second adjusting member 23 are respectively drivingly connected to the connecting portion. The first adjusting member 22 is used for driving the support member 21 to move in a first direction, and the second adjusting member 23 is used for driving the support member 21 to move in a second direction. Both the first direction and the second direction are the radial directions of the receiving member 10, and the first direction is opposite to the second direction; wherein, a plurality of supporting portions are used for enclosing to form a circular structure along the circumference of the receiving member 10, and the circular structure is adapted to the inner wall of the cylinder body.

[0031] In this embodiment, the receiving member 10 is specifically a receiving plate, and the cross-section of the receiving plate is an annular structure, which can facilitate the circumferential arrangement of the plurality of adjusting components 20, rationally utilize the space of the receiving plate, and is beneficial to forming a circular structure by the plurality of supporting portions.

[0032] At the same time, each supporting portion is an arc structure, which is convenient for the plurality of supporting portions to cooperate with each other to form a circular structure.

[0033] In this embodiment, the first direction is X and the second direction is Y.

[0034] Optionally, in other embodiments, the cross-section of the receiving plate can also be set to other structures such as a square, as long as it can meet the circumferential arrangement requirements of the plurality of adjusting components 20.

[0035] The beneficial effects of the circularity correction and anti-deformation device for the cylinder body of the present invention are as follows: Before welding the cylinder body, first use the first adjusting member 22 to drive the support member 21 to move in the first direction, so as to reduce the inner diameter of the plurality of support portions that enclose to form a circular structure along the circumferential direction of the receiving member 10, which facilitates placing the circularity correction and anti-deformation device of the cylinder body into the cylinder body to be welded. Then, the operator drives the support member 21 to move in the second direction through the second adjusting member 23 to expand the inner diameter of the circular structure, so that the circular structure is adapted to the inner diameter of the cylinder body, thereby facilitating the support portion to support the inner wall of the cylinder body. This can prevent the cylinder body from deforming during welding and reducing the roundness of the cylinder body after welding. In addition, by replacing the support member 21, the cylinder body with different inner diameters can be adapted, so that the circularity correction and anti-deformation device of the cylinder body is supported and connected to the inner walls of cylinders with different inner diameters, which improves the applicable range of the circularity correction and anti-deformation device of the cylinder body to meet the user's usage requirements.

[0036] As Figures 1 to 5 shown, optionally, the support member 21 includes: a support plate 211 having a first side wall 213 and a second side wall 214 disposed opposite to each other along the radial direction of the receiving member 10. The first side wall 213 forms a support portion, and the second side wall 214 forms a connection portion. The second adjusting member 23 is drivingly connected to the second side wall 214; a connecting frame 212 is disposed on the second side wall 214. At least a part of the connecting frame 212 is movably connected to the receiving member 10, and the moving direction of the connecting frame 212 is parallel to the radial direction of the receiving member 10. The first adjusting member 22 is drivingly connected to the connecting frame 212; wherein, the first adjusting member 22 is used to drive the connecting frame 212 to move to drive the support plate 211 to move in the first direction, and the second adjusting member 23 is used to drive the support plate 211 to move in the second direction. Through the coordinated action of the first adjusting member 22 and the second adjusting member 23, the support plate 211 can move in the first direction (indirectly driven by the first adjusting member 22 driving the connecting frame 212 to move) and the second direction (directly driven by the second adjusting member 23). At the same time, the two-way adjustment of the first adjusting member 22 and the second adjusting member 23 can optimize the contact pressure distribution between the support plate 211 and the inner wall of the cylinder body, thereby avoiding the situation of excessive local pressure during the welding process and improving the bearing capacity of the support plate 211.

[0037] In this embodiment, both the first side wall 213 and the second side wall 214 are arc surface structures. This can not only facilitate the processing of the support plate 211, but also reduce the space required for installing the support plate 211, thereby helping to reduce the processing cost of the support plate 211. Of course, in other embodiments, the second side wall 214 can also be set as a flat surface structure. The specific setting should be selected according to the usage environment of the support plate 211, so as to improve the applicability of the support plate 211.

[0038] Meanwhile, the connecting frame 212 is formed by connecting multiple plate bodies. The above structure is simple and easy to process, which not only improves the processing efficiency of the connecting frame 212, but also reduces the production cost of the connecting frame 212.

[0039] As Figures 1 to 5 shown, optionally, the first adjusting member 22 includes: a first frame body 221 provided on the receiving member 10; a bolt 222 having a threaded section 224 and a connecting section 225 connected in sequence, the connecting section 225 being fixedly connected to the first frame body 221, and the threaded section 224 passing through the connecting frame 212; a nut 223 sleeved on the threaded section 224 and threadedly connected to the threaded section 224, the nut 223 being movable relative to the bolt 222 along the radial direction of the receiving member 10, and the nut 223 abutting against the side wall of the connecting frame 212 away from the middle of the receiving member 10 to drive the connecting frame 212 to move in the first direction. By providing the above structure, using the helical movement of the threaded section 224, the rotational movement of the bolt 222 can be converted into a linear movement, thereby driving the connecting frame 212 to move in the first direction. At the same time, the nut 223 abuts against the side wall of the connecting frame 212, which can provide a stable supporting force for the nut 223, ensuring that the connecting frame 212 remains stable during movement and is not prone to shaking or offset, thereby improving the stability of the overall structure.

[0040] Moreover, the thread adjustment is simple and reliable, which can not only meet the driving requirements for the connecting frame 212, but also facilitate maintenance to reduce the use cost of the device.

[0041] As Figures 1 to 5 shown, optionally, the second adjusting member 23 includes: a second frame body 231 provided on the receiving member 10; a setscrew 232, one end of the setscrew 232 passing through the second frame body 231 and threadedly connected to the second frame body 231, the other end of the setscrew 232 being drivingly connected to the second side wall 214, and the setscrew 232 being movable relative to the second frame body 231 along the second direction to drive the support plate 211 to move along the second direction. By rotating the setscrew 232, the moving distance along the second direction can be precisely controlled, which can ensure the adjustment accuracy of the second adjusting member 23 to meet the adjustment requirements of the device. At the same time, the connection between the setscrew 232 and the second frame body 231 can ensure that there is no loosening or displacement during the adjustment process, improving the overall stability.

[0042] In addition, by rotating the setscrew 232, the position of the support plate 211 can be adjusted. The above operation is simple and fast, improving the adjustment efficiency.

[0043] In other embodiments, the setscrew 232 can also be replaced by other structures such as a screw rod, as long as it can meet the requirement of driving the second adjusting member 23 to move in the second direction.

[0044] Optionally, a convex structure 30 is provided on one of the bottom of the connecting frame 212 and the receiving member 10, and a groove structure 40 adapted to the convex structure 30 is provided on the other of the bottom of the connecting frame 212 and the receiving member 10. The convex structure 30 and the groove structure 40 extend along the radial direction of the receiving member 10, and the convex structure 30 and the groove structure 40 are connected and matched to limit the position of the connecting frame 212 relative to the receiving member 10 in the circumferential direction of the receiving member 10. By providing the above structure, it is ensured that the connecting frame 212 will not rotate or shift relative to the receiving member 10 during use, thereby improving the stability of the overall structure of the adjusting assembly 20. At the same time, the cooperation between the convex structure 30 and the groove structure 40 increases the contact area between the connecting frame 212 and the receiving member 10, making the connection between the two more stable and reliable, and improving the durability of the device.

[0045] And the cooperation between the convex structure 30 and the groove structure 40 makes the installation between the connecting frame 212 and the receiving member 10 easier. During the installation process, it is only necessary to align the convex structure 30 with the groove structure 40 and push it in, thereby improving the installation efficiency of the two; when it is necessary to disassemble or replace the connecting frame 212, it is only necessary to pull out the convex structure 30 from the groove structure 40, and the operation is simple and fast, thereby improving the disassembly efficiency of the connecting frame 212.

[0046] In this embodiment, the convex structure 30 is provided at the bottom of the connecting frame 212, and the groove structure 40 is provided on the receiving member 10. Of course, the convex structure 30 can also be provided on the receiving member 10, and the groove structure 40 is provided at the bottom of the connecting frame 212. The specific setting situation should be selected according to the use situation of the device.

[0047] As Figure 4 shown, optionally, the adjusting assembly 20 further includes a limiting block 50. The limiting block 50 is disposed in the groove structure 40. The side wall of the limiting block 50 close to the middle of the receiving member 10 abuts against the groove wall of the groove structure 40, and the side wall of the limiting block 50 away from the middle of the receiving member 10 abuts against the outer wall of the connecting frame 212. The limiting block 50 is used to limit the displacement of the connecting frame 212 in the first direction. The limiting block 50 effectively limits the displacement of the connecting frame 212 in the first direction, ensuring that the connecting frame 212 will not exceed the predetermined moving range during use, thereby avoiding the situation that the support plate 211 collides with the edge of the receiving member 10 due to excessive movement, which is beneficial to protecting the structure of the assembly.

[0048] As Figure 1As shown, optionally, the roundness correction and anti-deformation device of the cylinder body further includes a monitoring component 60. The monitoring component 60 includes: a sensor 61 disposed on the support member 21. The sensor 61 is used to detect the position of the support member 21 relative to the first adjusting member 22 and generate a sensing signal; a transmitter, communicatively connected to the sensor 61. The transmitter is used to convert the sensing signal into a dimension signal of the inner diameter of the cylinder body; a display 62 disposed on the receiving member 10. The display 62 is communicatively connected to the transmitter to display the dimension signal. Among them, a plurality of sensors 61 are provided, and the sensors 61 are arranged in one-to-one correspondence with the support members 21. By setting the above structure, the sensor 61 can monitor the position of the support member 21 relative to the first adjusting member 22 in real time and generate corresponding sensing signals, ensuring the real-time and accuracy of data during the roundness correction process. At the same time, the transmitter is used to convert the sensing signal into a dimension signal of the inner diameter of the cylinder body and is displayed in real time through the display 62, so that the operator can understand the inner diameter dimension of the cylinder body at any time, thereby adjusting the roundness correction parameters in time and improving the roundness correction efficiency.

[0049] As Figure 1 shown, optionally, the roundness correction and anti-deformation device of the cylinder body further includes a lifting ring 70. The lifting ring 70 is disposed on the receiving member 10, and the receiving member 10 is connected to an external component through the lifting ring 70. Through the above structure, the operator only needs to pass a hook or other structure of the external component through the lifting ring 70 to achieve a stable connection between the receiving member 10 and the external component; when it is necessary to disassemble the receiving member 10 and the external component, only the connection between the external component and the lifting ring 70 needs to be released. The above operation is simple and fast, facilitating the transfer and installation of the roundness correction and anti-deformation device of the cylinder body between different working locations, thereby improving the transfer efficiency of the roundness correction and anti-deformation device of the cylinder body.

[0050] In other embodiments, the lifting ring 70 can also be replaced by other structures such as a lifting hole, as long as the lifting requirements of the roundness correction and anti-deformation device of the cylinder body can be met.

[0051] In this embodiment, four lifting rings 70 are provided and are evenly arranged along the circumference of the receiving member 10. Of course, in other embodiments, the number of lifting rings 70 can also be set to other values such as five or six, as long as the lifting requirements of the device can be met.

[0052] As Figure 1As shown, optionally, each adjusting component 20 includes two second adjusting members 23, and the two second adjusting members 23 are respectively located on both sides of the first adjusting member 22 in the circumferential direction of the receiving member 10. Such an arrangement enables the adjusting component 20 to adjust the support plate 211 from two different directions. This increases the flexibility and diversity of adjustment, enabling the circularity correction device to adapt to more complex circularity correction requirements. At the same time, the two second adjusting members 23 can be adjusted independently, making it more convenient for the operator to adjust the circularity correction device. For example, when fine-tuning a certain local area is required, only the corresponding second adjusting member 23 needs to be adjusted, thereby improving the accuracy and precision of circularity correction.

[0053] In other embodiments, the number of second adjusting members 23 included in each adjusting component 20 can also be set to other values such as four or six, as long as the adjustment requirements of the device can be met.

[0054] As Figure 1 shown, optionally, the circularity prevention and deformation device of the cylinder body has eight adjusting components 20, and the eight adjusting components 20 are evenly distributed along the circumferential direction of the receiving member 10. Of course, in other embodiments, the number of adjusting components 20 can also be set to other values such as four or five. The specific setting should be selected according to the usage environment of the device and will not be elaborated here. Although the present invention is disclosed as above, the protection scope of the present invention is not limited thereto. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of the present invention, and these changes and modifications will all fall within the protection scope of the present invention.
