The application field of rotary joints covers almost all processing and manufacturing industries, such as metallurgy, machine tools, printing and dyeing, pharmaceuticals, etc., and also includes the photovoltaic industry.

[0003] In the related art, the repair method of a rotary joint is usually to manually hold the rotary joint and use a flat file or a grinder to grind the rotary joint.

Therefore, for rotary joints that are damaged and have problems such as leakage, in most cases they will be scrapped and recycled, and only in a few cases will they be repaired, which makes the waste of resources caused by the workpiece more and more serious.

DETAILED DESCRIPTION

[0028] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the specific implementation manner of the present application will be clearly and completely described below in conjunction with the drawings in the implementation manner of the present application.

[0029] The present application embodiment provides a Figure 1The clamping device 100 shown is mainly used for clamping a rotary joint. The clamping device 100 includes a base 11 and at least two clamping assemblies 12. The clamping assemblies 12 are arranged along a preset direction. In this embodiment, the clamping assemblies 12 are arranged along the length direction 101 of the base 11. The clamping assembly 12 includes a fixed module 121, a movable module 122 and a first horizontal adjustment member 123. The fixed module 121 is fixedly connected to the base 11, the movable module 122 is slidably connected to the base 11, the movable module 122 can move along the width direction of the base 11, and the first horizontal adjustment member 123 is connected to the base 11, and the first horizontal adjustment member 123 can drive the movable module 122 to translate in a direction close to or away from the fixed module 121. The clamping device 100 also includes at least two height adjustment assemblies 13. The height adjustment assembly 13 is mounted on the base 11, and a single height adjustment assembly 13 is used to adjust the height of a single clamping assembly 12 accordingly. The horizontal heights of the clamping assemblies 12 are adjusted by the multiple height adjustment assemblies 13, so that the workpieces to be processed clamped by the clamping assemblies 12 can be at the same height, which is convenient for processing the workpieces to be processed. The clamping device 100 can clamp multiple workpieces to be processed at the same time, and the clamped workpieces to be processed can be ground by a surface grinder or other device, thereby improving the processing efficiency of the workpieces to be processed.

[0030] As an optional embodiment, the first horizontal adjustment member 123 can make the moving module 122 approach or move away from the fixed module 121. The first horizontal adjustment member 123 can be abutted against the moving module 122, or can be fixedly connected to the moving module 122. In this embodiment, the first horizontal adjustment member 123 is a screw, and the end of the screw is abutted against the moving module 122. By installing a linkage member at the abutment between the end of the screw and the moving module 122, the screw and the moving module 122 are mutually limited. One screw can be used to adjust the position of a moving module 122, and multiple screws can also be used to adjust the position of a moving module 122. Using multiple screws to adjust the position of a moving module 122 can improve the accuracy and stability of the adjustment. Rotating the screw can make the screw move along the width direction 102 of the base 11, and the screw remains rotatably connected and penetrates the base 11, and the base 11 is provided with a matching thread on the inner side of the perforation according to the screw. When it is necessary to clamp the workpiece to be processed, the object to be clamped can be placed between the fixed module 121 and the movable module 122, and the screw rod is rotated to push the screw rod in the direction close to the fixed module 121, and the end of the screw rod presses against the movable module 122 and moves in the direction close to the fixed module 121, thereby gradually reducing the distance between the fixed module 121 and the movable module 122 to achieve clamping of the workpiece to be processed. When it is necessary to remove the workpiece to be processed, the screw rod is rotated in the opposite direction, and the screw rod moves in the direction away from the fixed module 121, thereby driving the movable module 122 to move in the direction away from the fixed module 121, and the clamping assembly 12 releases the clamped workpiece to be processed, and the workpiece to be processed can be easily removed. The first horizontal adjustment member 123 can also be fixedly connected to the movable module 122. When the first horizontal adjustment member 123 moves toward the fixed module 121 , the movable module 122 follows the first horizontal adjustment member 123 to approach the fixed module 121 ; when the first horizontal adjustment member 124 moves away from the fixed module 121 , the movable module 122 follows the first horizontal adjustment member 123 to move away from the fixed module 121 .

[0031] As an optional embodiment, the clamping device 100 also includes a second horizontal adjustment member 14, which is installed on the base 11. The second horizontal adjustment member 14 can drive at least two moving modules 122 to move along the width direction 102. The second horizontal adjustment member 14 can be installed on the base 11 and electrically connected to each clamping assembly 12, and the position of the moving module 122 can be adjusted by electrical control or the like. The second horizontal adjustment member 14 can also be mechanically connected to at least two clamping assemblies 12, and the position of the moving module 122 can be adjusted by a mechanical structure. In this embodiment, the second horizontal adjustment member 14 adjusts the moving module 122 by a mechanical structure. Specifically, the second horizontal adjustment member 14 can be connected to a plurality of first horizontal adjustment members 123. Taking the second horizontal adjustment member 14 connecting all the first horizontal adjustment members 123 as an example, when the second horizontal adjustment member 14 moves in the direction close to the fixed module 121, the second horizontal adjustment member 14 drives all the first horizontal adjustment members 123 to move in the direction close to the fixed module 121, and the first horizontal adjustment member 123 drives the moving module 122 to move in the direction close to the fixed module 121, so that multiple workpieces to be processed can be clamped at the same time. When the second horizontal adjustment member 14 moves in the direction away from the fixed module 121, the second horizontal adjustment member 14 drives all the first horizontal adjustment members 123 to move in the direction away from the fixed module 121, and the first horizontal adjustment member 123 drives the moving module 122 to move in the direction away from the fixed module 121, so that multiple workpieces to be processed can be released at the same time. The second horizontal adjustment member 14 can improve the convenience of the clamping device 100. The second horizontal adjustment member 14 can also be directly connected to multiple moving modules 122, and the second horizontal adjustment member 14 directly controls the moving module 122 to move along the width direction 102.

[0032] As an optional implementation, Figure 2 As shown, the height adjustment component 13 includes a first height adjustment member 131 and a second height adjustment member 132. The first height adjustment member 131 is arranged between the fixed module 121 and the base 11, and the first height adjustment member 131 can make the fixed module 121 move along the height direction 103 of the base 11, and can adjust the height of the fixed module 121. The second height adjustment member 132 is arranged between the movable module 122 and the base 11, and the first height adjustment member 131 can adjust the fixed module 121 to move along the height direction 103, and can adjust the height of the movable module 122. The first height adjustment member 131 and the second height adjustment member 132 jointly adjust the height positions of the fixed module 121 and the movable module 122 in the clamping component 12, so that the fixed module 121 and the movable module 122 that cooperate with each other to clamp are located at the same height, and further make the processing plane of the workpiece to be processed located at the same height, which is convenient for processing the workpiece to be processed. The specific optional structure of the height adjustment component 13 can be a known mechanical structure that can adjust the height, such as a folding lifting platform, a lifting screw, etc.

[0033] As an optional implementation, Figure 3 As shown, a first notch 1211 is provided on one side of the fixed module 121 close to the movable module 122, and a second notch 1221 is provided on one side of the movable module 122 close to the fixed module 121. The first notch 1211 and the second notch 1221 are used to clamp the workpiece to be processed. When clamping, the workpiece to be processed can be placed between the first notch 1211 and the second notch 1221, and the movable module 122 is controlled to move toward the fixed module 121 by adjusting the first horizontal adjustment member 123, thereby reducing the distance between the movable module 122 and the fixed module 121, so that the first notch 1211 and the second notch 1221 abut against the workpiece to be processed, thereby clamping the workpiece to be processed.

[0034] As an optional embodiment, the shape of the first notch 1211 includes at least one of a V-shape, an arc shape, a semi-regular polygon, or other irregular shapes; the notch shape of the second notch 1221 is V-shaped (such as Figure 4 As shown), arc shape (as shown Figure 5 as shown) or semi-regular polygons or other irregular shapes (such as Figure 6 For workpieces with regular shapes such as rotary joints, cylindrical workpieces or regular prism workpieces, V-shaped notches, arc-shaped notches or semi-regular polygonal notches can be used for clamping. For workpieces with irregular shapes, irregular notches corresponding to the workpieces can also be used for clamping.

[0035] As an optional embodiment, the opening sizes of the first notch 1211 and the second notch 1221 are adjustable. When the size of the workpiece to be processed is large, the openings of the first notch 1211 and the second notch 1221 can be enlarged to improve the stability of the clamping. When the size of the workpiece to be processed is small, the openings of the first notch 1211 and the second notch 1221 can be reduced so that the first notch 1211 and the second notch 1221 can clamp the workpiece to be processed.

[0036] As an optional implementation, Figure 4 As shown, when the first notch 1211 is a V-shaped notch, a first angle adjustment member 1212 may be further installed on the fixed module 121. The first angle adjustment member 1212 can adjust the opening angle of the V-shaped notch of the fixed module 121. When the second notch 1221 is a V-shaped notch, a second angle adjustment member 1222 may be further installed on the movable module 122. The second angle adjustment member 1222 can adjust the opening angle of the V-shaped notch of the movable module 122. When the diameter of the workpiece to be processed is small, the opening angle of the V-shaped notch can be reduced to improve the stability of the clamping. When the diameter of the workpiece to be processed is large, the opening angle of the V-shaped notch can be increased to improve the stability of the clamping.

[0037] As an optional implementation, Figure 7 As shown, the fixed module 121 also includes a first process hole 1213, which is located inside the first notch 1211; the fixed module 121 also includes a second process hole 1223, which is located inside the second notch 1221. By leaving a gap between the first notch 1211 and the second notch 1221 facing the same direction, the first process hole 1213 and the second process hole 1223 are respectively provided, and the curvature of the first process hole 1213 and the second process hole 1223 are matched with the curvature of the outer wall of the cylindrical workpiece to be processed, the interference of the fixed die block 121 and the movable module 122 on the workpiece during the clamping process can be reduced, and the clamping effect can be further improved.

[0038] As an optional implementation, Figure 8 As shown, the movable module 122 is also provided with a limiting hole 1224. In this embodiment, the limiting hole 1224 is in a strip shape and can extend along the width direction 102. When the first horizontal adjustment member 123 adjusts the position of the movable module 122, the limiting hole 1224 can limit the movement direction of the movable module 122 to prevent the movable module 122 from being offset along the length direction 101. The limiting hole 1224 can ensure that when the movable module 122 moves, the first notch 1211 of the movable module 122 is always aligned with the second notch 1221 of the fixed module 121, thereby improving the clamping stability of the clamping assembly 12.

[0039] As an optional embodiment, a plurality of limiting holes 1224 may be provided on the moving module 122 to further limit the movement of the moving module 122. In this embodiment, two limiting holes 1224 are provided on the moving module 122, and the two limiting holes 1224 are arranged along the length direction 101. The two limiting holes 1224 can not only prevent the moving module 122 from being offset along the length direction 101, but also prevent the moving module 122 from rotating, so that the first notch 1211 is always aligned with the second notch 1221 of the fixed module 121, further improving the stability of the clamping of the clamping assembly 12.

[0040] As an optional embodiment, the clamping device 100 further includes a fixing member 15, which is inserted into the limiting hole 1224 and vertically fixedly connected to the base 11. When the fixing member 15 is locked, the movable module 122 is fixed on the base 11 and cannot move relative to the base 11. When the fixing member 15 is loosened, the movable module 122 can slide on the base 11 along the width direction 102.

[0041] As an optional embodiment, the clamping device 100 further includes a locking member 16. The locking member 16 is installed between adjacent moving modules 122. When the locking member 16 is in a locked state, the adjacent moving modules 122 can be fixed so that the adjacent moving modules 122 become a whole. When the locking member 16 is in a locked state, the adjacent moving modules 122 cannot move relative to each other, which is convenient for adjusting the position of the moving module 122 as a whole. When the locking member 16 is in an unlocked state, the adjacent moving modules 122 can move independently without being affected by each other, which is convenient for adjusting the position of a single moving module 122 separately.

[0042] In summary, the present application provides a clamping device 100. The clamping device 100 is equipped with multiple clamping assemblies 12, which can clamp multiple workpieces to be processed at the same time. When multiple workpieces to be processed need to be clamped, the workpieces to be processed can be placed between the fixed module 121 and the movable module 122 of each clamping assembly 12, and the position of the movable module 122 is adjusted by the first horizontal adjustment member 123, so that each clamping assembly 12 clamps the workpiece to be processed. Then, the height of the clamping is adjusted by the height adjustment assembly 13, so that the processing surfaces of each workpiece to be processed are at the same height, and processing can be carried out.

[0043] When multiple workpieces to be processed need to be clamped, the workpieces to be processed can be placed between the fixed module 121 and the movable module 122 of each clamping assembly 12, and the positions of the multiple movable modules 122 can be adjusted simultaneously by the second horizontal adjustment member 14, and each clamping assembly can be fine-tuned by the first horizontal adjustment member 13. The convenience of adjusting the multiple movable modules 122 can be improved by coarse adjustment of the second horizontal adjustment member 14; the accuracy of adjusting the clamping device 100 can be improved by fine adjustment of the first horizontal adjustment member 123; the time required for adjusting the clamping assembly 12 can be reduced by the cooperation between the first horizontal adjustment member 123 and the second horizontal adjustment member 14, thereby improving the convenience and accuracy of the clamping device 100.

[0044] When the workpiece to be clamped is too large or too small, the opening angles of the fixed module 121 and the movable module 122 can be adjusted by the first angle adjustment member 1212 and the second angle adjustment member 1222 to make the opening angles of the movable module 121 and the movable module 122 match the workpiece to be processed, thereby improving the clamping stability of the clamping assembly.

[0045] The clamping device 100 in the present application can clamp the workpieces to be processed at the same time, so that the workpieces to be processed can be ground using a surface grinder and other devices, saving labor costs. The clamping device 100 is simple to operate and easy to use, and can clamp multiple workpieces to be processed at the same time, thereby improving the processing efficiency of the workpieces to be processed.
