Description

Technical Field

[0001] The utility model relates to the technical field of slip ring testing equipment, in particular to a slip ring testing tool and a testing system. Background Art

[0002] In the traditional security field, products such as ball cameras need to rotate continuously. Ordinary wires may be damaged due to twisting. However, conductive slip rings can maintain stable transmission of signals and power in this rotating state, providing a flexible rotation environment for the system. Figure 1 As shown, the conductive slip ring 10 includes a rotor end 11, a stator end 12, a rotor lead 13 and a stator lead 14; one end of the rotor lead 13 is electrically connected to the rotor end 11, and the other end of the rotor lead 13 is connected to the second terminal 15; one end of the stator lead 14 is connected to the stator end 12, and the other end of the stator lead 14 is connected to the first terminal 16.

[0003] For conductive slip rings, the two major performance indicators are dynamic resistance and insulation resistance, which will directly affect the performance. Dynamic impedance is the change in contact resistance between the copper ring and the brush during the uniform rotation of the slip ring after power is applied. It is usually a fluctuating value and will be affected by factors such as foreign matter between the copper ring and the brush, insufficient pressure, and virtual contact.

[0004] At present, the dynamic resistance of the conductive slip ring is usually tested manually, specifically: manually rotate the rotor end of the conductive slip ring, and then use a resistance analyzer to measure the dynamic resistance of the conductive slip ring after rotation. However, this manual testing method is inefficient and cannot test the dynamic impedance at different speeds in real time, and thus cannot obtain the corresponding relationship between dynamic impedance and speed. Therefore, how to test the dynamic impedance of the conductive slip ring at different speeds in real time is an urgent problem to be solved in the industry. Utility Model Content

[0049] The current testing method for testing the conductive slip ring 10 is: fix the stator flange of the stator end 12 of the conductive slip ring 10 to the adapter plate, use a nylon fixing band to tie the rotor lead 13 to the motor output shaft, drive the rotor end 11 of the conductive slip ring 10 to rotate by the motor, and after completing the expected number of life cycles, manually rotate the rotor end 11, and then use a resistance tester to obtain the dynamic impedance of the conductive slip ring 10. However, this manual testing method is inefficient and cannot test the dynamic impedance at different speeds in real time, and thus cannot obtain the corresponding relationship between the dynamic impedance and the speed. Therefore, how to test the dynamic impedance of the conductive slip ring 10 at different speeds in real time is an urgent problem to be solved in the industry.

Along the length direction, the second lead fixing assembly 300 is arranged on the side of the stator fixing assembly 100 away from the first lead fixing assembly 200, and the second lead fixing assembly 300 is used to be detachably connected to the rotor lead 13 and the second end of the test instrument, so that the rotor lead 13 is electrically connected to the test instrument; the second lead fixing assembly 300 is also used to be movably connected to the second end of the test instrument;

[0053] The driving assembly 400 is used to drive the rotor end 11 and the second lead fixing assembly 300 to rotate synchronously, so that the second lead fixing assembly 300 can move relative to the testing instrument.

[0054] In this embodiment, the stator end 12 of the conductive slip ring 10 is fixed to the stator fixing assembly 100, and the stator lead 14 extends along the length direction and is detachably connected to the first lead fixing assembly 200, so that the stator lead 14 can be arranged neatly to avoid the problem of lead winding and knotting; in addition, the first lead fixing assembly 200 is also used to be detachably connected to the first end of the test instrument, so that the test instrument and the stator lead 14 are electrically connected to realize signal transmission. The rotor lead 13 extends along the length direction and is detachably connected to the second lead fixing assembly 300, so that the rotor lead 13 can be arranged neatly to avoid the problem of lead winding and knotting; in addition, the second lead fixing assembly 300 is also used to be detachably and movably connected to the second end of the test instrument, so when the driving assembly 400 drives the second lead fixing assembly 300 and the rotor end 11 to rotate synchronously, the second lead fixing assembly 300 can rotate relative to the test instrument to avoid the problem of wire winding and knotting of the test instrument.

[0055] Furthermore, the first lead fixing assembly 200 is used to electrically connect the stator lead 14 to the test instrument, and the second lead fixing assembly 300 is used to electrically connect the rotor lead 13 to the test instrument, so as to realize signal transmission. If the test instrument is a resistance tester, real-time testing of dynamic impedance at different speeds can be realized, which solves the problem that the testing means in the prior art cannot test the dynamic impedance of the conductive slip ring 10 at different speeds in real time, and at the same time improves the testing efficiency.

[0056] In some embodiments, the number of the stator fixing assemblies 100 may be at least two, so that at least two conductive slip rings 10 can be tested simultaneously, further improving the test efficiency.

[0057] In some embodiments, the driving assembly 400 is used to be connected to the rotor end 11 , and drives the second lead fixing assembly 300 by driving the rotor end 11 , so that the second lead fixing assembly 300 and the rotor end 11 rotate synchronously.

[0058] In some embodiments, the driving assembly 400 includes a first driving member 410 and a second driving member;

[0059] The first driving member 410 is used to connect with the rotor end 11 to drive the rotor end 11 to rotate; the second driving member is connected with the second lead fixing assembly 300 to make the second lead fixing assembly 300 rotate synchronously with the rotor end 11.

[0060] Optionally, the first driving member 410 includes a driving motor 411, a driving wheel 412, a driven wheel 413 and a transmission belt 414;

By providing the second lead fixing member 320 detachably connected to the second wiring terminal 15, it can be avoided that the rotor lead 13 is removed from the second wiring terminal 15 during the test process, and the non-destructive test of the conductive slip ring 10 can be realized without damaging the conductive slip ring 10.

[0065] It is understandable that the length direction is parallel to the straight line where the rotation center axis of the rotor end 11 is located.

Finally, the gate 321 is released, and the gate 321 presses the second terminal 15 downward under the action of the spring 322, so that the second terminal 15 is stably connected in the mounting hole 312.

[0071] Optionally, the spring-connected gate further includes a handle, which is connected to the gate 321 and is used to lift the gate 321 upward for easy operation.
