[0001] The present invention relates to the technical field of sealing testing, in particular to a conductive ring sealing performance testing device. Background Art

[0002] Conductive rings (also known as slip rings) are key components in many electromechanical devices, particularly in applications that require power or signals to be transmitted between rotating and stationary parts, such as wind turbines and radar antennas.

[0003] Currently, testing the sealing properties of conductive rings is a common practice. The process involves placing a conductive ring in the test area. After the test device completes the test and obtains the results, the ring is removed and classified as either a qualified or unqualified zone based on the test results. The next conductive ring to be tested is then placed in the test device, and the above steps are repeated. This process is not only cumbersome but also inefficient. Summary of the Invention

[0010] Furthermore, six openings are provided through the upper surface of the rotating plate, and the six openings are evenly divided into three groups.

[0019] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0020] See also Figure 1-Figure 5 A conductive ring sealing performance testing device includes an airtightness tester 13. A base 1 is provided below the airtightness tester 13. The upper surface of the base 1 is connected with a transposition mechanism. The output end of the transposition mechanism is connected with a rotating assembly. The upper end of the rotating assembly is connected with three tilting mechanisms. The output ends of the three tilting mechanisms are all connected with extrusion mechanisms. One side of the upper end of the base 1 is connected with an extension assembly, and the other end of the extension assembly is connected with a supporting assembly. The middle part of the supporting assembly is connected to the airtightness tester 13. Both ends of the supporting assembly are connected with a moving mechanism. The output end of the moving mechanism is connected with two clamping assemblies, and the two clamping assemblies are both connected to the airtightness tester 13.

[0021] like Figures 1 to 5 As shown, when the conductive ring sealing performance testing device of the present invention is used, the base 1 is first installed in a suitable position, and then the first conductive ring is placed inside the extrusion mechanism of the first tilting mechanism, and then the conductive ring is fixed by the extrusion mechanism to prevent the conductive ring from shaking and falling off.

[0022] Then start the transposition mechanism. After the transposition mechanism is started, the output end will rotate clockwise with the rotating component, and then the conductive ring inside the first extrusion mechanism can be rotated to the bottom of the air tightness tester 13. At the same time, the second conductive ring is installed and fixed inside the extrusion mechanism of the second tilting mechanism in the same way.

[0023] When the first conductive ring rotates to the bottom of the air tightness tester 13, the moving mechanism is started. After the moving mechanism is started, the output end will move toward the middle base 1 with the two clamping components at the same time, and in the process of moving, the two ends of the first conductive ring in the middle will be clamped.

[0024] After that, it is only necessary to start the air tightness tester 13, and the output end of the air tightness tester 13 can supply air to the inside of the conductive ring through the clamping component. At the same time, the internal sensors and detectors of the air tightness tester 13 can automatically determine whether there is air leakage in the conductive ring.

[0025] After the judgment is completed, the second conductive ring has also been installed. At this time, the transposition mechanism is started again. The transposition mechanism will continue to rotate the first conductive ring clockwise to the position of the third tilting mechanism. After that, the tilting mechanism can control the rotation of the extrusion mechanism based on the previously detected qualified or unqualified, and then release the extrusion mechanism. At this time, the conductive ring inside the extrusion mechanism can automatically slide to the qualified or unqualified area for collection under the action of gravity, which is convenient and quick.

[0026] It should be noted that the airtightness tester 13 is an existing mature technology, so its internal structure and working principle are not described in detail here.

[0027] As a preferred solution of the present invention, the shifting mechanism includes a shifting motor 28 and a shifting rod 30. A motor cavity 29 is opened in the middle of the upper surface of the base 1. The outer wall of the shifting motor 28 is fixedly connected to the inner wall of the motor cavity 29. The output shaft of the shifting motor 28 is fixedly connected to the lower end of the shifting rod 30, and the upper end of the shifting rod 30 is connected to the rotating assembly.

[0028] More specifically, when the conductive ring needs to be controlled to transpose, the transposition motor 28 only needs to be turned on, and the output shaft of the transposition motor 28 can drive the transposition rod 30 to rotate, and the rotation of the transposition rod 30 can drive the rotating assembly to rotate.

[0029] As a preferred solution of the present invention, the rotating assembly includes a rotating plate 4 and six raised frames 17. The middle part of the bottom surface of the rotating plate 4 is fixedly connected to the upper end of the shift rod 30. The lower ends of the six raised frames 17 are all fixedly connected to the upper surface of the rotating plate 4. The six raised frames 17 are evenly divided into three groups, and the three groups of raised frames 17 are respectively connected to the three tilting mechanisms.

[0030] More specifically, when the shift rod 30 rotates, it will rotate with the rotating plate 4 connected to it. When the rotating plate 4 rotates, the six raised frames 17 located above the rotating plate 4 can rotate together, and then can rotate with the tilting mechanism and other components located on the three groups of raised frames 17.

[0031] As a preferred solution of the present invention, the tilting mechanism includes a blanking motor 18, a rotating frame 20 and two rotating rods 19. The outer wall of the blanking motor 18 is fixedly connected to the side wall of one of the raised frames 17 in a group of raised frames 17. The adjacent ends of the two rotating rods 19 are respectively fixedly connected to the outer walls on both sides of the rotating frame 20. The outer walls of the two rotating rods 19 are respectively rotatably connected to the inner walls of the two raised frames 17 in the same group. One end of the rotating rods 19 away from the rotating frame 20 is fixedly connected to the output shaft of the blanking motor 18, and the rotating frame 20 is connected to the extrusion mechanism.

[0032] More specifically, when it is necessary to control the conductive ring located inside the extrusion mechanism to tilt and slide, it is only necessary to turn on the unloading motor 18. After the unloading motor 18 is started, the output shaft will rotate inside the two raised frames 17 through the rotating rod 19 with the rotating frame 20, so that the conductive ring can slide down by itself after the extrusion mechanism releases the limit.

[0033] As a preferred embodiment of the present invention, the extrusion mechanism includes an electric push rod 21, a No. 1 connecting block 22, a No. 1 semicircular plate 23, a No. 2 semicircular plate 24 and a No. 2 connecting block 26. The outer wall of the electric push rod 21 is fixedly connected to the upper surface of the outer wall of the rotating frame 20. The output end of the electric push rod 21 passes through the interior of the rotating frame 20 and is fixedly connected to the upper surface of the No. 1 connecting block 22. The bottom surface of the No. 1 connecting block 22 is fixedly connected to the outer wall of the No. 1 semicircular plate 23. The bottom surface of the No. 2 connecting block 26 is fixedly connected to the bottom surface of the inner wall of the rotating frame 20. The upper surface of the No. 2 connecting block 26 is fixedly connected to the outer wall of the No. 2 semicircular plate 24. A number of offset openings 25 are provided on the adjacent side of the No. 1 semicircular plate 23 and the No. 2 semicircular plate 24. The No. 1 semicircular plate 23 and the No. 2 semicircular plate 24 are slidably connected through the number of offset openings 25.

[0034] More specifically, when installing the conductive ring, you only need to place the conductive ring between the No. 1 semicircular plate 23 and the No. 2 semicircular plate 24 first, and then start the electric push rod 21. The electric push rod 21 extends outward to push the No. 1 semicircular plate 23 downward, thereby clamping the conductive ring between the No. 1 semicircular plate 23 and the No. 2 semicircular plate 24.

[0035] It should be noted here that: because different conductive rings may have different diameters, the offset openings 25 on the No. 1 semicircular plate 23 and the No. 2 semicircular plate 24 can be used to automatically adapt to the clamping of conductive rings of different diameters; of course, pressure sensors can be set inside the No. 1 semicircular plate 23 and the No. 2 semicircular plate 24 to monitor whether the clamping is stable. In addition, before clamping, the diameter of the conductive ring can be set in advance on the external controller, so as to control the electric push rod 21 to accurately extend a specific distance to achieve stable clamping.

[0036] As a preferred solution of the present invention, six openings 16 are provided through the upper surface of the rotating plate 4, and the six openings 16 are evenly divided into three groups. The three groups of openings 16 are respectively located on both sides of the three groups of elevated frames 17. The upper surface of the base 1 is provided with a No. 1 blanking port 3 and a No. 2 blanking port 27. The No. 1 blanking port 3 and the No. 2 blanking port 27 are matched and aligned with the three groups of openings 16. Three partition plates 2 are fixedly connected to the side of the base 1 close to the No. 1 blanking port 3 and the No. 2 blanking port 27. The three partition plates 2 are located on both sides of the No. 1 blanking port 3 and the No. 2 blanking port 27.

[0037] More specifically, by setting the opening 16 and the partition plate 2, when the blanking motor 18 controls the No. 1 semicircular plate 23 and the No. 2 semicircular plate 24 to tilt toward the No. 1 blanking port 3 or the No. 2 blanking port 27, it is only necessary to loosen the electric push rod 21, and the conductive rings inside the No. 1 semicircular plate 23 and the No. 2 semicircular plate 24 can slide into the No. 1 blanking port 3 or the No. 2 blanking port 27 by themselves due to gravity, so that the conductive rings can slide more smoothly from the No. 1 blanking port 3 or the No. 2 blanking port 27 to the qualified area or the unqualified area for collection.

[0038] As a preferred solution of the present invention, the extension assembly includes three connecting frames 5, one end of each of the three connecting frames 5 is fixedly connected to the side wall of the upper end of the base 1, and the other end of each of the three connecting frames 5 is connected to the support assembly.

[0039] More specifically, by providing an extension assembly, it is possible to provide support to the support assembly while preventing the support assembly and the moving mechanism from obstructing the rotation and reversing of the three tilting mechanisms.

[0040] As a preferred solution of the present invention, the support assembly includes a U-shaped frame 6 and a middle frame 15. The side wall of the U-shaped frame 6 is fixedly connected to the end of the three connecting frames 5 away from the base 1, the middle part of the U-shaped frame 6 is fixedly connected to the lower end of the middle frame 15, the upper surface of the middle frame 15 is fixedly connected to the bottom surface of the air tightness tester 13, and the two ends of the U-shaped frame 6 and the upper end of the middle frame 15 are connected to the moving mechanism.

[0041] More specifically, by providing a support assembly, not only can stable support be provided for the moving mechanism and the air tightness tester 13 , but the height of the air tightness tester 13 can also be raised to prevent the air tightness tester 13 from obstructing the tilting mechanism and the conductive ring.

[0042] As a preferred solution of the present invention, the moving mechanism includes a clamping motor 7, a bidirectional screw rod 8 and a sliding rod 9. The outer wall of the clamping motor 7 is fixedly connected to the side wall of one end of the U-shaped frame 6. The output shaft of the clamping motor 7 is fixedly connected to one end of the bidirectional screw rod 8. The bidirectional screw rod 8 and the sliding rod 9 are arranged parallel to each other up and down. The bidirectional screw rod 8 and the sliding rod 9 both pass through the U-shaped frame 6 and the middle frame 15. The outer wall of the bidirectional screw rod 8 and the inner wall of the point where the U-shaped frame 6 and the middle frame 15 pass through are both rotatably connected. The outer wall of the sliding rod 9 and the inner wall of the point where the U-shaped frame 6 and the middle frame 15 pass through are both fixedly connected. The two clamping components are both connected to the bidirectional screw rod 8 and the sliding rod 9.

[0043] More specifically, when it is necessary to control the clamping assembly to move closer, it is only necessary to turn on the clamping motor 7, and the output shaft of the clamping motor 7 can drive the bidirectional screw rod 8 to rotate. After the bidirectional screw rod 8 rotates, the two clamping assemblies connected to the surface of the bidirectional screw rod 8 and the sliding rod 9 can be displaced at the same time, so that the conductive ring can be clamped from both sides of the conductive ring at the same time.

[0044] As a preferred solution of the present invention, the clamping assembly includes an L-shaped plate 10, a splint 11 and an air pipe 14. One end of the L-shaped plate 10 is sleeved on the outside of the bidirectional screw rod 8 and the sliding rod 9. The inner wall of the L-shaped plate 10 is threadedly connected to the outer wall of the bidirectional screw rod 8. The inner wall of the L-shaped plate 10 is slidingly connected to the outer wall of the sliding rod 9. The other end of the L-shaped plate 10 is fixedly connected to the side wall of the splint 11. An air outlet 12 is opened through the middle of the splint 11. The side of the splint 11 away from the base 1 is fixedly connected to the lower end of the air pipe 14. The upper end of the air pipe 14 is fixedly connected to the output end of the air tightness tester 13. The air tightness tester 13, the air pipe 14 and the air outlet 12 are internally connected.

[0045] More specifically, when the bidirectional screw 8 rotates, the L-shaped plate 10 connected to the surface of the bidirectional screw 8 can undergo lateral displacement, and when the L-shaped plate 10 moves, it will also move with the splint 11, so that it can cooperate with another splint 11 to clamp the conductive ring from both ends of the conductive ring, and then start the air tightness tester 13. The air tightness tester 13 can be used to extract or supply air with the help of two air pipes 14 to determine whether there is any leakage in the conductive ring.

[0046] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
