[0002] Slip rings are used to conduct electricity. They are applied to rotating parts to transmit energy and signals through contact with the rotating parts. When the rotating parts move, the wires on the slip ring will deviate slightly. After long-term use, the wires deviating back and forth can easily damage the solder joints. Therefore, slip rings need to undergo durability testing after production to reduce the failure rate after being put into use.

[0003] Existing slip ring testing equipment typically involves fixing the slip ring and testing the solder joints of the wires between the upper and lower plates of the slip ring by slightly rotating the upper and lower plates. However, the method of fixing the slip ring is generally quite complex, while simple fixing affects the fixing effect, which has a certain impact on the efficiency and results of the test. Therefore, a test fixture for an electric slip ring testing device is proposed. Utility Model Content

[0022] like Figure 1 As shown, the present invention provides a test fixture for an electric slip ring testing device, comprising a base plate 1 and an electric slip ring, with a lower plate 8 and an upper plate 9 on the slip ring. A reducer 2 is fixedly installed on the top of the base plate 1, a servo motor 3 is fixedly installed on one side of the bottom of the reducer 2, and a hollow rotating module 4 is installed on the top of the reducer 2. The servo motor 3 is connected to the hollow rotating module 4 through the reducer 2. A mounting platform 5 is fixedly installed on the top of the reducer 2 in the middle of the hollow rotating module 4, and a lower plate clamp assembly 6 is fixedly installed on the top of the mounting platform 5. An upper plate clamp assembly 7 is fixedly installed on one side of the top of the hollow rotating module 4. The lower plate 8 is movably engaged in the lower plate clamp assembly 6, and the upper plate 9 is movably engaged in the upper plate clamp assembly 7.

[0023] like Figure 2 As shown, the lower plate clamp assembly 6 includes a first mounting plate 61 disposed on the top of the mounting platform 5. A first hinge block 62 is fixedly mounted on one side of the top of the first mounting plate 61. A first pressure plate 63 is hingedly fixed on the first hinge block 62. A first magnetic block 64 is fixedly mounted on the top side of the first mounting plate 61 away from the first hinge block 62. The bottom of the first pressure plate 63 is movably connected to the first magnetic block 64. A first rubber pad 65 is fixedly mounted on the bottom of the first pressure plate 63. The lower plate 8 is movably connected to the first mounting plate 61. The bottom of the first rubber pad 65 is movably connected to the top of the lower plate 8.

[0024] like Figure 3As shown, the upper plate clamp assembly 7 includes a vertical plate 71 fixedly installed on the top of the hollow rotating module 4. A second mounting plate 72 is vertically fixedly installed on the top of the vertical plate 71. A second hinge block 73 is fixedly installed on one side of the top of the second mounting plate 72. A second pressure plate 74 is hingedly fixedly installed on the second hinge block 73. A second magnetic block 75 is fixedly installed on the top side of the second mounting plate 72 away from the second hinge block 73. The bottom of the second pressure plate 74 is movably connected to the second magnetic block 75. A second rubber pad 76 is fixedly installed on the bottom of the second pressure plate 74. The upper plate 9 is movably connected to the second mounting plate 72. The bottom of the second rubber pad 76 is movably connected to the top of the upper plate 9.

[0025] A wiring port 91 is fixedly installed on the surface of the upper plate 9. A wire hole 92 is opened through the surface of the upper plate 9. The wire hole 92 is located above the lower plate clamp assembly 6. Several positioning holes 93 are opened through the surface of the upper plate 9.

[0026] like Figure 4 As shown, an angle sensor 10 is fixedly installed on the top of the reducer 2 on one side of the hollow rotating module 4, and a trigger 11 is fixedly installed on the bottom of the hollow rotating module 4 near the angle sensor 10. The trigger 11 is movably connected to the angle sensor 10.

[0027] Working steps: First, assemble the device, fix the base plate 1 on the testing equipment, and connect the circuit of the device. Open the first pressure plate 63 and the second pressure plate 74 to separate the first pressure plate 63 from the first magnetic block 64 and the second pressure plate 74 from the second magnetic block 75. Place the upper plate 9 on the slip ring onto the second mounting plate 72. After adjusting the position, use bolts to fix the upper plate 9 through the positioning holes 93. Then place the lower plate 8 on the first mounting plate 61 and connect the first pressure plate 63 to the second magnetic block 75. The second pressure plate 74 is reset, so that the first magnetic block 64 is magnetically connected to the first pressure plate 63, and the second magnetic block 75 is magnetically connected to the second pressure plate 74. The lower plate clamping assembly 6 and the upper plate clamping assembly 7 clamp the lower plate 8 and the upper plate 9, and the wire of the electric slip ring is passed out from the wire hole 92 and plugged into the wiring port 91. The servo motor 3 is started. The servo motor 3 drives the hollow rotating module 4 to rotate through the transmission of the reducer 2. The upper plate 9 and the lower plate 8 rotate relative to each other, and the durability test of the wire solder joint on the electric slip ring is performed.

[0028] Working Principle: The specifications of reducer 2 and servo motor 3 are selected, and the device is assembled. The lower plate 8 and upper plate 9 of the slip ring are clamped on the lower plate clamp assembly 6 and upper plate clamp assembly 7. After the servo motor 3 is reduced in speed by reducer 2, it drives the hollow rotating module 4 to rotate, which drives the upper plate clamp assembly 7 to rotate synchronously. This causes the upper plate 9 clamped on the upper plate clamp assembly 7 and the lower plate 8 clamped on the lower plate clamp assembly 6 to rotate relative to each other. The durability of the wires between the lower plate 8 and the upper plate 9 is tested. The selection of the specifications of reducer 2 and servo motor 3 makes it easier to control the relative rotation angle of the lower plate 8 and the upper plate 9, and facilitates the acquisition of rotation angle data. The trigger 11 triggers the angle sensor 10 to detect the relative rotation angle of the lower plate 8 and the upper plate 9, which facilitates data recording. The lower plate clamp assembly 6 and the upper plate clamp assembly 7 are both fixed to the lower plate 8 and the upper plate 9 of the slip ring by magnetic attraction. The fixing method is simple and stable, which helps to improve the practicality of the device and improve the testing efficiency of the slip ring.
