[0038] The above drawings have shown clear embodiments of the present application, which will be described in more detail later. These drawings and text descriptions are not intended to limit the scope of the present application in any way, but to illustrate the concept of the present application to those skilled in the art by referring to specific embodiments. DETAILED DESCRIPTION

[0039] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the following exemplary embodiments do not represent all implementations consistent with the present application. Instead, they are merely examples of devices and methods consistent with some aspects of the present application as detailed in the appended claims.

[0040] In the related art, when leveling a large spherical surface product, it is necessary to use a lifting device to lift the spherical surface product, adjust the lifting and extension lengths in each direction to keep the spherical surface product level, and then weld a support frame on the spherical surface product so that the support frame can support the spherical surface product to keep it level. However, welding the support frame to the surface of the spherical surface product is not only difficult to operate, but also has low positioning efficiency and can damage the surface of the spherical surface product.

[0041] In view of the above technical problems, an embodiment of the present application provides a leveling device. The leveling device includes a mounting seat and a plurality of support members and a plurality of adjustment mechanisms arranged on the mounting seat, and the plurality of support members and the plurality of adjustment mechanisms are arranged in an array around the same center and arranged on the mounting seat. In addition, a rolling member is arranged on the side of each support member away from the mounting seat. In this way, after the workpiece is mounted on the leveling device, it is beneficial to reduce the difficulty of moving the workpiece, so as to level the workpiece. The plurality of adjustment mechanisms are each provided with a pressure head, and the pressure head can move in a direction close to or away from the mounting seat. In the process of leveling the workpiece, the pressure head is supported on the surface of the side of the workpiece away from the mounting seat. In this way, if the surface of the side of the workpiece away from the mounting seat is not parallel to or coincides with the preset plane, the surface of the side of the workpiece away from the mounting seat will first contact with part of the pressure head. As the pressure head moves toward the side close to the mounting seat, the pressure head will push the workpiece to deflect and move on the plurality of support members, so that the surface of the side of the workpiece away from the mounting seat can be parallel to or coincide with the preset plane under the push of the plurality of pressure heads. Exemplarily, in actual production, the preset plane can be a horizontal plane. Therefore, the leveling device provided above is beneficial to reducing the difficulty of leveling and can also prevent the surface of the workpiece from being damaged.

[0042] The following specific embodiments are used to describe in detail the technical solution of the present application and how the technical solution of the present application solves the above-mentioned technical problems. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described in detail in some embodiments. Figures 1 to 11 , the embodiments of the present application are described.

[0043] According to some optional embodiments, the leveling device provided in the present application can be used for leveling a workpiece 10 having a spherical surface 11. In some optional embodiments, the surface of at least one end of the workpiece 10 is an arcuate convex surface, and the arcuate convex surface is a surface of revolution. Optionally, the spherical surface 11 is an arcuate convex surface with one end of the workpiece 10 being a surface of revolution. Exemplarily, the spherical surface 11 can be, but is not limited to, a spherical surface.

[0044] In some optional embodiments, referring to Figure 1 and Figure 2 The leveling device includes a mounting seat 20, a plurality of first support members 30 and a plurality of first adjustment mechanisms 40. The mounting seat 20 is a basic structural member and can provide a mounting foundation for other components.

[0045] Reference Figure 1 In some optional embodiments, the mounting seat 20 has an assembly surface 21. Exemplarily, the assembly surface 21 may be a reference surface. In some optional embodiments, after the workpiece 10 is leveled, the surface of the workpiece 10 on the side away from the assembly surface 21 is parallel to the assembly surface 21. In some usage scenarios, the assembly surface 21 of the mounting seat 20 is horizontally arranged.

[0046] Reference Figures 1 to 3 , a plurality of first support members 30 are arranged on the mounting seat 20 in a circular array around the first center. Exemplarily, the spacing between each first support member 30 and the first center is equal. Exemplarily, a plurality of first support members 30 are arranged at intervals around the first center. In some optional embodiments, the spacing between any two adjacent first support members 30 is equal. In some optional embodiments, the heights of any two first support members 30 in a direction perpendicular to the assembly surface 21 are equal. In this way, the assembly surface 21 can be used as a reference surface for leveling the workpiece 10, and it is beneficial to reduce the difficulty of preparing the leveling device.

[0047] According to some optional embodiments, referring to Figure 1 and Figure 2 , the mounting seat 20 can be set in a disc shape. Optionally, when the mounting seat 20 is set in a disc shape, the first center can be the center of the assembly surface 21 of the mounting seat 20. In some optional embodiments, the leveling device includes four first support members 30. The corresponding center angle between two adjacent first support members 30 is a right angle.

[0048] In some optional embodiments, the extension direction of the first support member 30 is perpendicular to the assembly surface 21. The extension direction of the first support member 30 can be Figure 8 The direction shown by the y-axis.

[0049] In some optional embodiments, the leveling device further includes a crossbeam. Exemplarily, the crossbeam is parallel to the assembly surface 21, and the two ends of the crossbeam are respectively connected to the two first support members 30. Further optionally, the leveling device includes multiple crossbeams, and the multiple crossbeams connect the multiple first support members 30 as a whole. In this way, the crossbeam can improve the stability of the multiple first support members 30 installed on the mounting seat 20, so as to improve the bearing capacity of the multiple first support members 30.

[0050] In some optional embodiments, a rolling member 31 is provided at one end of the first support member 30 away from the assembly surface 21. The rolling member 31 is rotatably connected to the first support member 30, and at least part of the rolling member 31 protrudes from the end surface of the first support member 30 away from the assembly surface 21. Figure 3, the rolling member 31 may be, but is not limited to, a spherical steel ball disposed at the end of the first support member 30. Exemplarily, the spherical steel ball is connected to the first support member 30 by a spherical pair. In addition, the rolling member 31 at least partially protrudes from the end of the first support member 30. In this way, when the workpiece 10 is assembled to the first support member 30, the first support member 30 can provide support for the workpiece 10 through the rolling member 31. Since the rolling member 31 is rotatable. For this reason, when the workpiece 10 needs to be moved during the leveling process, the rolling member 31 can be used to rotate relative to the end of the first support member 30 to reduce the resistance to the movement of the workpiece 10, which is beneficial to reduce the difficulty of leveling the workpiece 10.

[0051] Reference Figures 1 to 3 , a plurality of first adjustment mechanisms 40 are arranged in a circular array around the second center on the mounting base 20. The first center coincides with the second center, that is, a plurality of first adjustment mechanisms 40 and a plurality of first support members 30 are arranged in a circular array around the same center, which is beneficial to prevent the workpiece 10 from warping during the leveling process and is beneficial to improving the leveling accuracy of the workpiece 10. In some optional embodiments, a plurality of first adjustment mechanisms 40 are evenly distributed around the second center, that is, the corresponding central angles between any two adjacent first adjustment mechanisms 40 are equal. Exemplarily, the leveling device includes at least three first adjustment mechanisms 40. In an optional embodiment, the leveling device includes four first adjustment mechanisms 40.

[0052] In some optional embodiments, the first adjustment mechanism 40 includes a second support member 41, a pressing head 42, and a first driving assembly 43 disposed on the second support member 41. The pressing head 42 is connected to the first driving assembly 43. The first driving assembly 43 drives the pressing head 42 to move relative to the second support member 41 in a direction away from or close to the assembly surface 21.

[0053] Reference Figure 2 When the workpiece 10 is assembled to the leveling device, the rolling element 31 is supported on the spherical surface 11 of the workpiece 10 , and the pressing head 42 stops at the edge of the workpiece 10 away from the assembly surface 21 .

[0054] In some optional embodiments, the extension direction of the second support member 41 is perpendicular to the mounting surface 21. The extension direction of the second support member 41 can be Figure 8 The direction shown by the y-axis.

[0055] In an optional embodiment, the first driving assembly 43 may be, but is not limited to, a hydraulic cylinder, a pneumatic cylinder, a screw mechanism, a connecting rod mechanism or a cam mechanism.

[0056] In some optional embodiments, such as Figure 2 and Figure 8As shown, the first driving assembly 43 includes a driving motor 431 and a lead screw 432. Optionally, the lead screw 432 can be threadedly matched with the second support member 41. The first end of the lead screw 432 is connected to the pressure head 42, and the second end of the lead screw 432 is transmission-connected to the driving motor 431, and the driving motor 431 can drive the lead screw 432 to rotate relative to the second support member 41, and then drive the pressure head 42 to move in a direction close to or away from the mounting seat 20 through the lead screw 432.

[0057] In some optional embodiments, the extension direction of the lead screw 432 is perpendicular to the assembly surface 21. In this way, when the pressing head 42 pushes the workpiece 10 downward, it is beneficial to reduce the bending moment of the lead screw 432.

[0058] Exemplarily, in the process of leveling the workpiece 10, the spherical surface 11 of the workpiece 10 is first supported on a plurality of first support members 30. Then, the pressing heads 42 in the first adjustment mechanism 40 are adjusted so that the heights of the pressing heads 42 in the plurality of first adjustment mechanisms 40 are consistent in a direction perpendicular to the assembly surface 21. Then, the pressing heads 42 in the plurality of first adjustment mechanisms 40 are adjusted to move synchronously in a direction close to the mounting seat 20.

[0059] In the process of the pressing head 42 moving toward the mounting seat 20, if there is an inclined surface on the surface of the workpiece 10 away from the mounting seat 20, the pressing head 42 on the upturned side of the workpiece 10 first stops at the surface of the workpiece 10 away from the mounting seat 20. As the pressing head 42 moves toward the mounting seat 20, the force acting on the workpiece 10 is unbalanced, so that the workpiece 10 can move on the multiple first support members 30. In the case that there is no deflection on the surface of the workpiece 10 away from the mounting seat 20, the pressing heads 42 in the multiple first adjustment mechanisms 40 act on the workpiece 10 with equal forces. In this way, the forces acting on the workpiece 10 in various directions are balanced, and the workpiece 10 will not move relative to the multiple first support members 30.

[0060] In summary, in the process of leveling the workpiece 10 with the spherical surface 11 using the adjustment device provided in the above embodiment, it is only necessary to place the workpiece 10 on the first support member 30 and use the pressure head 42 in the first adjustment mechanism 40 to simultaneously press down the workpiece 10. This is beneficial to simplify the leveling operation of the workpiece 10 with the spherical surface 11 and reduce the difficulty of leveling.

[0061] In some optional embodiments, the leveling device provided by the present application can be used for the end cover of a large tank, such as the leveling of the head structure. In this way, during the leveling process, the rolling member 31 at the end of the first support member 30 can be used to reduce the difficulty of adjusting the position of the workpiece 10. In addition, it is also possible to avoid welding the support frame on the outer surface of the workpiece 10 to avoid damaging the surface of the workpiece 10 by welding.

[0062] In some optional embodiments, the first adjustment mechanism 40 is movably disposed on the mounting seat 20, and the first adjustment mechanism 40 moves in a direction away from or close to the second center along the assembly surface 21. In some optional embodiments, the first adjustment mechanism 40 can move radially along a circle in the assembly surface 21 with the second center as the center.

[0063] Exemplarily, the first adjustment mechanism 40 may be slidably matched with the mounting seat 20 , so that the first adjustment mechanism 40 may slide relative to the mounting seat 20 .

[0064] The adjustment device provided in the above embodiment can adapt to workpieces 10 of different diameters by moving the first adjustment mechanism 40 toward or away from the second center during the leveling process of the workpiece 10. For example, when the diameter of the workpiece 10 to be leveled is large, the first adjustment mechanism 40 is moved toward the direction away from the second center. When the diameter of the workpiece 10 to be leveled is small, the first adjustment mechanism 40 is moved toward the direction close to the second center.

[0065] According to some optional embodiments, Figure 3 and Figure 8 As shown, the leveling device further includes a second driving assembly 50. The second driving assembly 50 is disposed on the mounting seat 20, and the second driving assembly 50 drives the first adjusting mechanism 40 to move along the mounting surface 21 in a direction away from or close to the second center.

[0066] In some optional embodiments, the second drive assembly 50 may include a plurality of sub-drive assemblies, and one sub-drive assembly corresponds to one first adjustment mechanism 40. Exemplarily, the sub-drive assemblies are connected to the first adjustment mechanisms 40 in a one-to-one correspondence, and the sub-drive assemblies can drive the corresponding first adjustment mechanisms 40 to move along the assembly surface 21 in a direction close to or away from the second center.

[0067] Exemplarily, the sub-drive assembly may be a hydraulic cylinder, a pneumatic cylinder, a screw mechanism, a connecting rod mechanism, a cam mechanism and / or a rack and pinion mechanism. For this reason, this embodiment does not limit the specific type of the sub-drive assembly.

[0068] The leveling device provided in the above embodiment can use the second driving assembly 50 to adjust the position of the first adjustment mechanism 40 to adapt to the workpieces 10 to be leveled with different diameters.

[0069] In some optional embodiments, when assembling the workpiece 10 onto the first support member 30, the first adjustment mechanism 40 may be driven by the second drive assembly 50 to move in a direction away from the second center, so that a larger avoidance space may be formed between the plurality of first adjustment mechanisms 40. Therefore, the leveling device provided in the above embodiment is beneficial to preventing the first adjustment mechanism 40 from colliding with the workpiece 10, and reducing the difficulty of assembling the workpiece 10 onto the leveling device.

[0070] Reference Figures 3 to 6 In some optional embodiments, the second driving assembly 50 includes a center column 51, a sleeve 52 and a plurality of first connecting rods 53. The center column 51 is perpendicular to the assembly surface 21 and connected to the mounting seat 20. Exemplarily, the center column 51 is disposed at the second center.

[0071] Reference Figure 7 , Figures 9 to 11 , a plurality of first adjustment mechanisms 40 are arranged at intervals around the central column 51, and the distance between any two first adjustment mechanisms 40 and the central column 51 is equal. Exemplarily, a plurality of second support members 41 are arranged at intervals around the central column 51, and the distance between any two second support members 41 and the central column 51 is equal.

[0072] Reference Figures 2 to 6 , the sleeve 52 is sleeved on the central column 51, and the sleeve 52 and the central column 51 are slidably matched. Exemplarily, the sleeve 52 can move along the central column 51 in a direction close to or away from the mounting seat 20. Further optionally, a first connecting rod 53 corresponds to a first adjustment mechanism 40. The first end of the first connecting rod 53 is rotatably connected to the sleeve 52, and the second end of the first connecting rod 53 is rotatably connected to the corresponding first adjustment mechanism 40. In the process of the sleeve 52 sliding along the first connecting rod 53, the sleeve 52 drives the first adjustment mechanism 40 to move in a direction away from or close to the central column 51 through the first connecting rod 53.

[0073] In some optional embodiments, the first connecting rod 53 can rotate relative to the sleeve 52 in a plane perpendicular to the assembly surface 21. Optionally, the first connecting rod 53 and the sleeve 52 are rotatably connected via a first rotating shaft. The axis of the first rotating shaft is parallel to the assembly surface 21.

[0074] In some optional embodiments, the first connecting rod 53 can rotate relative to the first adjusting mechanism 40 in a plane perpendicular to the mounting surface 21. Optionally, the first connecting rod 53 and the first adjusting mechanism 40 are rotationally connected via a second rotating shaft. The axis of the second rotating shaft is parallel to the mounting surface 21.

[0075] In the leveling device provided by the above embodiment, the sleeve 52 can drive the first adjustment mechanism 40 to move synchronously relative to the mounting seat 20 through the multiple first connecting rods 53, which can improve the efficiency of adjusting the first adjustment mechanism 40 and also help ensure that the spacing between each first adjustment mechanism 40 and the central column 51 is equal. Therefore, the leveling device provided by this embodiment is beneficial to further reduce the operating difficulty of the leveling device and improve the leveling accuracy.

[0076] Reference Figures 1 to 3In some optional embodiments, the mounting seat 20 is provided with a guide portion 22, and the guide portion 22 has a guide groove 221. One end of the second support member 41 away from the pressure head 42 is slidably matched with the guide groove 221, and the second support member 41 can move along the guide groove 221 in a direction away from or close to the center column 51. Exemplarily, one end of the second support member 41 away from the pressure head 42 is at least partially located in the guide groove 221, and the second support member 41 is slidably matched with the inner side wall of the guide groove 221.

[0077] In some optional embodiments, the extending direction of the guide groove 221 is parallel to the assembly surface 21 , and the extending direction of the guide groove 221 is a radial direction of a circle with the second center as the center.

[0078] In the above embodiment, the guide portion 22 can constrain the movement trajectory of the second support member 41 relative to the mounting seat 20 through the guide groove 221, thereby helping to improve the stability of the movement of the second support member 41 relative to the mounting seat 20. In addition, the guide portion 22 is also helpful in ensuring that the distance between the second support member 41 and the center column 51 in each first adjustment mechanism 40 is equal by limiting the movement trajectory of the second support member 41, thereby helping to ensure the leveling accuracy of the leveling device.

[0079] In some optional embodiments, such as Figure 2 , Figure 4 and Figure 8 As shown, a sliding seat 413 is provided at one end of the second support member 41 away from the pressure head 42. One of the side walls of the sliding seat 413 and the inner side wall of the guide groove 221 is provided with a limiting protrusion 414, and the other is provided with a limiting groove 222, and the extension direction of the limiting groove 222 is parallel to the extension direction of the guide groove 221. At least part of the limiting protrusion 414 is located in the limiting groove 222, and the limiting protrusion 414 is slidably matched with the inner wall of the limiting groove 222. In some optional embodiments, the second support member 41 can be connected to the sliding seat 413 by bolts. Of course, the second support member 41 can also be connected to the sliding seat 413 by welding, riveting, etc. For this reason, the present embodiment does not limit the specific connection method of the second support member 41 and the sliding seat 413.

[0080] In the above embodiment, the limiting protrusion 414 cooperates with the limiting groove 222 to prevent the second support member 41 from tilting, thereby improving the stability of the second support member 41 to avoid the deflection of the second support member 41 affecting the leveling accuracy.

[0081] In some optional embodiments, the second support member 41 is perpendicular to the assembly surface 21. In this way, when the workpiece 10 is assembled to the leveling device, it is beneficial to reduce the bending moment of the second support member 41 and prevent the second support member 41 from bending and deforming. In the above embodiment, the limiting protrusion 414 and the limiting groove 222 are beneficial to ensure that the second support member 41 is perpendicular to the assembly surface 21.

[0082] In some optional embodiments, such as Figure 2 and Figure 8 As shown, the second driving assembly 50 further includes a plurality of second connecting rods 54. One second connecting rod 54 corresponds to one first adjusting mechanism 40. Exemplarily, the first end of the second connecting rod 54 is rotatably connected to the sleeve 52, the second end of the second connecting rod 54 is rotatably connected to the corresponding first adjusting mechanism 40, and the first connecting rod 53 and the second connecting rod 54 connected to the same first adjusting mechanism 40 are parallel to each other.

[0083] In the above embodiment, the first connecting rod 53 and the second connecting rod 54 are arranged in parallel. In this way, the first connecting rod 53 and the second connecting rod 54 can be respectively connected to different positions of the first adjusting mechanism 40, which is beneficial to maintain the posture of the first adjusting mechanism 40 and prevent the first adjusting mechanism 40 from being deflected during the movement relative to the center column 51.

[0084] In some optional embodiments, the first connecting rod 53 and the second connecting rod 54 are parallel and spaced apart in the vertical direction. Further optionally, the length of the first connecting rod 53 is equal to the length of the second connecting rod 54. In this way, the sleeve 52, the first connecting rod 53, the second connecting rod 54 and the corresponding first adjustment mechanism 40 can form a parallelogram linkage mechanism. During the movement of the sleeve 52 along the central column 51, the first adjustment mechanism 40 remains parallel to the sleeve 52. Therefore, this embodiment is beneficial to prevent the first adjustment mechanism 40 from being deflected during the movement relative to the mounting seat 20.

[0085] In some optional embodiments, such as Figures 2 to 6 As shown, the second drive assembly 50 also includes a screw 55, a transmission block 56 and an elastic member 57. The center column 51 has a receiving cavity 511 and a guide hole 512. The guide hole 512 is arranged on the side wall of the center column 51, and the guide hole 512 passes through the side wall of the center column 51 and is connected with the receiving cavity 511, and the guiding direction of the guide hole 512 is perpendicular to the assembly surface 21. The elastic member 57 and the transmission block 56 are both arranged in the receiving cavity 511. The transmission block 56 is slidably matched with the guide hole 512, and at least a part of the transmission block 56 passes through the guide hole 512 and is connected to the sleeve 52. Exemplarily, the guide hole 512 can be a square hole, and the size of the guide hole 512 in the direction perpendicular to the assembly surface 21 is larger than the size of the transmission block 56 in the direction perpendicular to the assembly surface 21.

[0086] In some optional embodiments, the first end of the elastic member 57 stops below the bottom of the accommodating cavity 511, the second end of the elastic member 57 stops against the transmission block 56, and the elastic member 57 is configured to push the transmission block 56 to move in a direction away from the assembly surface 21. Exemplarily, the elastic member 57 stops at a side of the transmission block 56 close to the mounting seat 20. Exemplarily, the elastic member 57 is a spring, and the elastic member 57 is in a compressed state, so that the elastic member 57 can generate an elastic force that pushes the transmission block 56 to move in a direction away from the assembly surface 21.

[0087] Reference Figures 4 to 5 In some optional embodiments, the screw rod 55 is threadedly matched with the central column 51, and the screw rod 55 stops at a side of the transmission block 56 away from the elastic member 57. Exemplarily, the extension direction of the screw rod 55 is perpendicular to the assembly surface 21.

[0088] For example, when the sleeve 52 needs to move toward the mounting seat 20, the screw 55 can be rotated to move the screw 55 relative to the center column 51 toward the mounting seat 20. During the movement, the screw 55 pushes the transmission block 56 toward the mounting seat 20, thereby driving the sleeve 52 to move toward the mounting seat 20.

[0089] In the above embodiment, the first adjustment mechanism 40 can also be self-locked by the screw 55 and the elastic member 57, that is, when there is no relative rotation between the screw 55 and the center column 51, it can be ensured that there is no relative sliding between the first adjustment mechanism 40 and the mounting seat 20. In addition, in the above embodiment, the transmission block 56 is connected to the sleeve 52 through the guide hole 512, which is also beneficial to prevent the sleeve 52 from rotating around the center column 51.

[0090] According to some optional embodiments, Figure 2 , Figure 3 , Fig. 9 and Fig.10 As shown, the second support member 41 includes a first support column 411 and a first support arm 412. The first end of the first support column 411 is connected to the mounting seat 20, and the second end of the first support column 411 is rotatably matched with the first end of the first support arm 412. Exemplarily, the first support column 411 is vertically arranged on the mounting seat 20, that is, the first support column 411 is perpendicular to the assembly surface 21. Figure 2 The first support arm 412 can rotate around a first axis relative to the first support column 411 , the first axis is perpendicular to the assembly surface 21 , and the first driving assembly 43 and the pressure head 42 are disposed at the second end of the first support arm 412 .

[0091] In some optional embodiments, the first support arm 412 can rotate relative to the first support column 411 between a first position and a second position. Fig. 9, when the first support arm 412 rotates to the first position, the extension direction of the first support arm 412 is the first direction. The first direction is the tangent direction of a circle with the second center as the center and the distance between the first support column 411 and the center column 51 as the radius. Fig.10 When the first support arm 412 rotates to the second position, the extension direction of the first support arm 412 is the second direction. The second direction is the radial direction of a circle with the second center as the center.

[0092] Reference Fig. 9 Before the workpiece 10 is assembled to the first support member 30, the first support arm 412 can be deflected in a direction away from the second center, so that a larger escape space can be formed between the plurality of first adjustment mechanisms 40, thereby preventing the first support arm 412 in the first adjustment mechanism 40 from blocking the workpiece 10 from being installed on the first support member 30. In addition, the leveling device provided in this embodiment is also beneficial to prevent the workpiece 10 from being supported by the first adjustment mechanism 40 and the first adjustment mechanism 40 on the wall from being crushed.

[0093] Furthermore, after the workpiece 10 is assembled onto the first support member 30 , the first support arm 412 can be rotated so that the ram 42 on the first support arm 412 can be opposite to the side of the workpiece 10 away from the mounting seat 20 , so as to prepare for the ram 42 to clamp the workpiece 10 downward.

[0094] Further, the height of each pressing head 42 is adjusted by the first driving assembly 43 so that the height of each pressing head 42 is consistent. Then, the first driving assembly 43 in the plurality of first adjusting mechanisms 40 synchronously drives the pressing head 42 to move downward so that the pressing head 42 can stop against the side of the workpiece 10 away from the mounting seat 20. In the case where the pressing heads 42 in the plurality of first adjusting mechanisms 40 all stop against the side of the workpiece 10 away from the mounting seat 20, the surface of the side of the workpiece 10 away from the mounting seat 20 is leveled, and it can be ensured that the corresponding center of the workpiece 10 is opposite to the first center. Exemplarily, in the case where the spherical surface 11 of the workpiece 10 is a spherical surface, the spherical center corresponding to the spherical surface 11 is opposite to the first center in a direction perpendicular to the assembly surface 21.

[0095] In some optional embodiments, the second support member 41 further includes a power member, which is respectively connected to the first support arm 412 and the first support column 411 , so that the power member can drive the first support arm 412 to rotate relative to the first support column 411 .

[0096] In some optional embodiments, the first support arm 412 may be driven to rotate relative to the first support column 411 by, but is not limited to, a hydraulic cylinder, a pneumatic cylinder, an electric motor, etc.

[0097] During the leveling process, the first adjustment mechanism 40 can be driven to move relative to the mounting base 20, or the first support arm 412 can be driven to rotate relative to the first support column 411, so that the pressure head 42 on the first adjustment mechanism 40 is equal to the distance from the second center in a direction parallel to the assembly surface 21.

[0098] According to some optional embodiments, Figure 1 and Figure 3 As shown, the leveling device further includes a second adjustment mechanism 60. The second adjustment mechanism 60 includes a third support member 61, a driving member and a transmission wheel 62. For example, the third support member 61 is a basic structural member, which can provide support for the driving member and the transmission wheel 62.

[0099] Reference Figure 1 and Figure 3 , the third support member 61 is disposed on the mounting seat 20. The transmission wheel 62 is in transmission cooperation with the third support member 61. The driving member is connected to the transmission wheel 62, and the driving member drives the transmission wheel 62 to rotate relative to the third support member 61 around the second axis, and the second axis is perpendicular to the assembly surface 21. When the workpiece 10 is assembled to the leveling device, the transmission wheel 62 stops against the outer peripheral wall of the workpiece 10, and the transmission wheel 62 drives the workpiece 10 to rotate around the first center.

[0100] In the above embodiment, the second adjustment mechanism 60 can be used to drive the workpiece 10 to rotate in a preset plane. Exemplarily, the second adjustment mechanism 60 drives the workpiece 10 to rotate in a horizontal plane to adjust the angle of the workpiece 10. Exemplarily, the side wall of the transmission wheel 62 is provided with an anti-slip groove to increase the friction between the transmission wheel 62 and the workpiece 10, so as to drive the workpiece 10 to rotate through the friction between the transmission wheel 62 and the workpiece 10.

[0101] In some optional embodiments, a rolling ball 421 is disposed on the pressure head 42, and the rolling ball 421 is rotatably matched with the pressure head 42, and at least part of the rolling ball 421 protrudes from the surface of the pressure head 42 on the side close to the mounting seat 20. Exemplarily, the rolling ball 421 is connected to the pressure head 42 through a spherical pair.

[0102] In the above embodiment, the workpiece 10 can be rotated when the pressure head 42 is lower than the workpiece 10, which is beneficial to reduce the resistance encountered by the workpiece 10 during the rotation process.

[0103] In some optional embodiments, the leveling device may include a plurality of second adjustment mechanisms 60. Optionally, the plurality of second adjustment mechanisms 60 are arranged on the mounting seat 20 in a circular array around the first center. In some optional embodiments, the leveling device includes at least three second adjustment mechanisms 60.

[0104] Reference Fig.11In an optional embodiment, the leveling device includes four second adjustment mechanisms 60. This is beneficial to improving the force balance in all directions of the workpiece 10, and further beneficial to keeping the workpiece 10 in a leveled state.

[0105] In some optional embodiments, the third support member 61 includes a second support column 611 and a second support arm 612. Exemplarily, the second support column 611 is vertically arranged on the mounting seat 20. The first end of the second support column 611 is connected to the mounting seat 20. The second end of the second support column 611 is connected to the second support arm 612. Exemplarily, the first end of the second support arm 612 is rotatably connected to the second end of the second support column 611, and the second support column 611 can rotate around a third axis relative to the second support column 611. The third axis is perpendicular to the assembly surface 21. The transmission wheel 62 is arranged at the second end of the second support arm 612. In this way, the transmission wheel 62 can be moved in a direction close to or away from the first center by rotating the second support arm 612.

[0106] For example, when the rotation of the workpiece 10 needs to be adjusted circumferentially, the second support arm 612 can be rotated to make the transmission wheel 62 approach the workpiece 10 and stop against the side wall of the workpiece 10, so that the transmission wheel 62 can drive the workpiece 10 to rotate through friction.

[0107] In addition, the second adjustment mechanism 60 can be adapted to workpieces 10 of different diameters by adjusting the second support arm 612 to rotate relative to the second support column 611 .

[0108] In some optional embodiments, the third support member 61 further includes a power member connected to the second support column 611 and the second support arm 612, so as to drive the second support arm 612 to rotate relative to the second support column 611 through the power member. Exemplarily, the power member driving the second support arm 612 to rotate relative to the second support column 611 may be, but is not limited to, a cylinder, a hydraulic cylinder, a hydraulic motor, an electric motor, etc.

[0109] In some optional embodiments, the transmission wheel 62 may be connected to a motor, so that the transmission wheel 62 is driven to rotate by the motor, thereby driving the workpiece 10 to rotate, thereby achieving adjustment of the circumferential angle of the workpiece 10 .
