Description

Technical Field

[0001] The invention relates to the technical field of conductive slip ring testing, and in particular to a testing system and method for conductive slip rings. Background Art

[0002] Conductive slip rings are also called conductive rings, slip rings, collector rings, and convergence rings. They can be used in any electromechanical system that requires continuous rotation and needs to transmit power and signals from a fixed position to a rotating position. Conductive slip rings can improve system performance, simplify system structure, and avoid twisting of wires during rotation.

[0003] Conductive slip rings include Figure 1 The slip ring stator 32 and the slip ring rotor 31 shown in the figure are composed of. When they rotate relative to each other, the brush wire 33 slides in close contact with the slide groove on the slip ring structure 34, and the transmission of electric energy or signal is realized by sliding contact between the slip ring structure 34 and the brush. When the slip ring rotor 31 changes its rotation direction instantaneously, the relative motion state between the slip ring rotor 31 and the slip ring stator 32 changes. This change may affect the position and contact state of the contact point, such as the contact area and the tightness of the contact, so that the resistance changes, thereby affecting the stability of the current.

[0004] In applications such as ships, heavy machinery, and engineering machinery, the equipment is often subjected to high vibration and impact. These external forces may directly cause a sudden change in the rotation direction of the conductive slip ring rotor or aggravate the wear of internal parts. When detecting the stability of the transmission current of the conductive slip ring, the traditional test system needs to use a multimeter to connect the two terminals of the conductive slip ring, and then make the stator and rotor of the conductive slip ring rotate relative to each other. Generally, it can only detect the resistance state of the conductive slip ring under normal conditions, and cannot simulate the situation when the relative rotation direction between the rotor and the stator changes rapidly and instantaneously, and cannot realize the test of the conductive slip ring's conductive performance in this environment. Therefore, a test system and method for conductive slip rings are proposed. Summary of the invention

[0005] The purpose of the present invention is to provide a testing system and method for a conductive slip ring, so as to solve the problem raised in the above background technology that "the traditional testing system needs to use a multimeter to connect the two terminals of the conductive slip ring when detecting the stability of the transmission current of the conductive slip ring, and then make the stator and the rotor of the conductive slip ring rotate relative to each other. Generally, it can only detect the resistance state of the conductive slip ring under normal conditions, and cannot simulate the situation when the relative rotation direction between the rotor and the stator changes instantly and rapidly, and cannot realize the test of the conductive performance of the conductive slip ring under such environment."

[0006] To achieve the above object, the present invention provides the following technical solution: a testing system for a conductive slip ring, comprising a base plate, a mounting mechanism is provided above the base plate, and a rotating mechanism for driving a slip ring rotor and a slip ring stator to rotate is installed on the surface of the mounting mechanism;

[0010] The rotation state of the slip-ring stator and the slip-ring rotor is monitored by the through-beam photoelectric sensor.

The wire will not be entangled if the direction is changed in time, and multiple relative states are formed between the slip-ring rotor and the slip-ring stator. The resistance of the conductive slip-ring can be tested when the rotor rotates normally or suddenly turns.

[0023] Under the above settings, when clamping and positioning the slip ring product, Spring 2 is in a compressed state. When the test is over and the slip ring product needs to be removed, the gripping rod is rotated to drive the threaded ring and the extrusion ring to rotate, so that the extrusion ring no longer squeezes the cylinder and the ball, and Spring 2 extends, driving the arc clamping plate away from the slip ring product, making it easier to remove the arc clamping plate.

[0024] In addition, the present invention also provides a method for using a testing system for a conductive slip ring, comprising the following steps:

The transmission rod 44 drives the fixed turntable 21 and the slip ring stator 32 to rotate. Every time the fixed turntable 21 rotates half a circle, the blocking rod 49 on the fixed turntable 21 blocks the light beam when passing the right-side opposite-beam photoelectric sensor 413. The right-side opposite-beam photoelectric sensor 413 sends a signal to make the transposition cylinder 48 on the fixed turntable 21 drive the T-shaped block 42 to transpose to the other end of the slide rail 41, thereby changing the rotation direction of the fixed turntable 21 and the slip ring stator 32, so that the slip ring stator 32 can appear in two states: rotating in the same direction as the slip ring rotor 31 and rotating in the opposite direction, and the slip ring stator 32 and the slip ring rotor 31 can switch back and forth between the two states, and measure the resistance of the slip ring product 3 in the two states.
