Description

Technical Field

[0001] The present invention relates to the technical field of conductive slip ring production, in particular to a conductive slip ring performance evaluation device suitable for harsh environmental conditions. Background Art

[0002] Conductive slip rings, key components for transmitting power, signals, and data between rotating and stationary objects, are often used in harsh environments such as high vibration, strong shock, and drastic temperature fluctuations. Therefore, stringent requirements are placed on the performance and reliability of conductive slip rings. Accurately evaluating the dynamic contact performance (such as contact resistance stability, insulation, and durability) of conductive slip rings under simulated or real harsh working conditions is crucial to ensuring equipment reliability and safety. However, existing evaluation equipment has the following drawbacks: During testing, the support of the slip ring is unstable, and strong vibration and shock can easily cause the slip ring to micro-displace or even loosen in the fixture. This not only interrupts the test, but also makes the test data unable to truly reflect the performance of the slip ring under harsh working conditions, making the evaluation meaningless. Summary of the Invention

[0003] To this end, the present invention proposes a conductive slip ring performance evaluation device suitable for harsh environmental conditions to solve the problems raised in the above background technology.

[0004] To achieve the above object, the present invention provides the following technical solution: a conductive slip ring performance evaluation device suitable for harsh environmental conditions, comprising:

[0005] a base, in which a first screw slide module is installed;

[0006] The workbench is slidably connected to the top surface of the base and is driven by the driving module of the first screw-type slide module to slide forward and backward;

[0007] An adjustable clamping mechanism is mounted on a workbench, and the adjustable clamping mechanism is capable of fixedly supporting the inner ring wall of the slip ring;

[0008] A frame is fixed on the base, and a second screw slide module is installed on the top of the frame;

[0009] And a slide seat, which is matched and slidably connected to two slide posts fixed in the frame and is driven by the driving module of the second screw slide module to slide up and down. A slip ring performance detection mechanism is fixed on the front of the slide seat.

[0010] Further, preferably, when the adjustable clamping mechanism is moved to directly below the slip ring performance detection mechanism, the adjustable clamping mechanism and the slip ring performance detection mechanism are coaxially arranged.

[0011] Further, preferably, the adjustable clamping mechanism includes:

[0012] a lower shelf plate, which is fixed on the workbench;

[0013] The upper plate is fixed to the lower plate by a plurality of connecting columns. The top surface of the upper plate is provided with a plurality of limiting grooves in a circumferential array, and a slider is provided in each limiting groove for sliding matching.

[0014] The support plates have the same number as the limiting slide grooves and are arranged in a circular array on the upper frame plate, and each of the support plates is fixedly connected to the corresponding slider;

[0015] And a driving mechanism, which can drive each supporting plate to move outward or inward synchronously, thereby locking or releasing the slip ring.

[0016] Furthermore, preferably, at least two through holes are provided through the wall of each support plate, a vacuum adsorption component is fixed in each through hole, and each vacuum adsorption component has a vacuum pump for vacuuming.

[0017] Furthermore, preferably, the support plate adopts an arc-shaped plate structure.

[0018] Furthermore, preferably, the vacuum adsorption assembly includes:

[0019] An adsorption seat is fixed in the corresponding through hole, an outer port of the adsorption seat is fixedly connected to a suction cup, and an inner port of the adsorption seat is connected to a vacuum pump via an air pipe;

[0020] a support frame fixed to the inner wall of the support plate;

[0021] and a telescopic rod connected between the adsorption seat and the support frame, wherein a second spring is wound on the side wall of the telescopic rod.

[0022] Furthermore, preferably, the driving mechanism includes:

[0023] An adapter shaft is rotatably mounted at the center of the lower frame plate and driven by a motor, wherein a threaded cavity is provided in the adapter shaft, and a threaded block is threadedly connected in the threaded cavity;

[0024] A driving rod is arranged in a space surrounded by a plurality of support plates, wherein the bottom end of the driving rod penetrates into the threaded cavity and is fixedly connected to the threaded block;

[0025] And a telescopic member, wherein the driving rod and each supporting plate are rotatably connected with two telescopic members.

[0026] Furthermore, preferably, the two telescopic members between the support plate and the driving rod are always arranged in parallel.

[0027] Furthermore, preferably, a spring 1 is connected between the two movable ends of each telescopic member.

[0028] The present invention adopts the above technology and has the following beneficial effects compared with the existing technology:

[0029] 1. A motor drives the adapter shaft and threaded block, driving the drive rod up and down. Parallel telescopic members then synchronously drive multiple curved support plates radially inward or outward, allowing the clamping mechanism to securely, stably, and automatically center slip rings of varying inner diameters. This eliminates the need for fixture replacement, significantly improving the equipment's versatility and testing efficiency, making it particularly suitable for testing high-volume, small-batch applications.

[0030] 2. An adjustable curved support plate is used to support and fix the slip ring from the inner wall, and vacuum adsorption (suction cup) is used to effectively overcome the problem of slip rings being easily displaced or loosened in harsh environments (such as vibration and impact). The inner wall support provides strong mechanical gripping force, and vacuum adsorption increases the adhesion and stability of the contact surface. The spring 2 in the vacuum adsorption component provides a buffer, allowing the suction cup to adapt to the slight unevenness of the slip ring inner wall, ensuring the adsorption force while avoiding the possible damage to the slip ring surface caused by hard contact. This is especially important for slip rings with high precision or surface treatment. BRIEF DESCRIPTION OF THE DRAWINGS

[0040] An adjustable clamping mechanism 6 is mounted on a workbench 7 and is capable of fixing and supporting the inner ring wall of the slip ring;

[0041] The frame 1 is fixed on the base 8, and the second screw slide module 3 is installed on the top of the frame 1;

[0042] And the slide 4, which is matched and slidably connected to the two slide posts 2 fixed in the frame 1, and is driven by the driving module of the second screw slide module 3 to slide up and down, and a slip ring performance detection mechanism 5 is fixed on the front of the slide 4.

[0044] Specifically, ensure that when the workbench moves to the testing position, the clamping mechanism (fixing the slip ring) is strictly coaxial with the slip ring performance testing mechanism above. This is the basis for key tests such as rotational contact resistance, insulation, and dynamic performance, and minimizes test errors caused by eccentricity.

[0045] In this embodiment, the adjustable clamping mechanism 6 includes:

[0046] Lower shelf plate 604, which is fixed on the workbench 7;

[0049] And a driving mechanism, which can drive each support plate 601 to move outward or inward synchronously, thereby locking or releasing the slip ring.

[0056] Specifically, an adjustable arc-shaped support plate is used to support and fix the slip ring from the inner wall, and vacuum adsorption (suction cup) is used to effectively overcome the problem of slip ring displacement or loosening in harsh environments (such as vibration and impact). The inner wall support provides strong mechanical gripping force, and vacuum adsorption increases the adhesion and stability of the contact surface.

[0057] The spring 2 in the vacuum adsorption assembly provides a buffer, which enables the suction cup to adapt to the slight unevenness of the inner wall of the slip ring, ensuring the adsorption force while avoiding the possible damage to the slip ring surface caused by hard contact.

[0063] Specifically, a motor drives the adapter shaft and threaded block, driving the drive rod up and down. Parallel telescopic members (linkages) then synchronously drive multiple curved support plates radially inward or outward, allowing the clamping mechanism to securely, stably, and automatically center slip rings of varying inner diameters. This eliminates the need for fixture replacement, significantly improving the device's versatility and testing efficiency, making it particularly suitable for testing high-volume, small-batch applications.
