Description

Technical Field

[0001] This invention specifically relates to the field of conductive slip ring manufacturing technology, and more specifically to a conductive slip ring testing platform with switchable testing modes. Background Technology

[0002] As a key component for achieving continuous power or signal transmission between rotating and stationary parts, the dynamic contact performance of conductive slip rings (such as contact resistance stability, signal transmission integrity, and smoothness of operation) directly determines the reliability and lifespan of equipment. Therefore, precise and efficient dynamic performance testing of conductive slip rings is essential during the manufacturing and quality inspection processes.

[0003] Currently, mainstream conductive slip ring testing methods typically employ fixed test probes or test fixtures requiring manual adjustment. However, these testing methods have the following significant drawbacks: conductive slip rings of different models and specifications have significantly different contact ring diameters. At present, when testing slip rings of different diameters, it is usually necessary to stop the machine and replace them with special test probes or fixtures that match the specific slip ring size. This replacement process is not only complex and time-consuming, increasing non-testing time, but also requires high skill from operators and is prone to introducing human error or causing physical damage to the probe or slip ring. Summary of the Invention

[0004] To address these issues, the present invention proposes a conductive slip ring testing platform with switchable testing modes.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a conductive slip ring testing platform with switchable testing modes, comprising:

[0020] And a push cylinder, which is fixed inside the cylinder, the drive end of the push cylinder being connected to the drive part of each drive arm assembly.

[0021] Furthermore, as a preferred embodiment, a conical plug is slidably fitted to the bottom of the cylinder, and a compression spring connects the plug to the cylinder.

[0022] Furthermore, preferably, the detection element includes:

[0026] Furthermore, preferably, the drive arm assembly includes:

[0027] The diagonal brace is inclined and rotatably connected between the cylinder and the adjusting rod;

[0028] A slider is slidably disposed in a groove, and an ear seat is fixed on the outside of the slider. A push-pull rod is rotatably connected between the ear seat and the middle of the diagonal brace.

[0029] And a baffle plate, which is disposed inside the cylinder and fixedly connected to the slider, and the slider is driven by a push cylinder.

[0030] Furthermore, as a preferred embodiment, the outer diameter of the baffle is larger than the width of the groove opening.

[0037] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0038] Example: Please refer to the appendix. Figure 1-4 This invention provides a technical solution: a conductive slip ring testing platform with switchable testing modes, comprising:

[0039] Turntable 3 is rotatably mounted on the base plate and is driven to rotate by a servo motor;

[0040] Clamping plates 5, which are provided in multiples and are mounted in a circular array on the table surface of turntable 3;

[0041] And multiple testing machines, which are set up in multiple locations and installed in corresponding positions on the turntable 3;

[0042] Specifically, the circumferential array chucks on the turntable can simultaneously hold multiple conductive slip rings to be tested. Combined with multiple independent testing machines (each corresponding to a chuck station), the platform can simultaneously test multiple slip rings, greatly improving test throughput and efficiency, and meeting the batch testing needs of the production line.

[0043] The testing machine consists of an X-axis slide module 1, a Y-axis slide module 2, a frame 4, and a smoothness testing mechanism. The X-axis slide module 1 is fixed on the turntable 3. The Y-axis slide module 2 is fixed on the sliding module of the X-axis slide module 1. The frame 4 for mounting the smoothness testing mechanism is fixed on the sliding module of the Y-axis slide module 2.

[0044] In this embodiment, a three-jaw chuck is installed inside the chuck 5.

[0045] In this embodiment, the smoothness testing mechanism includes:

[0046] Backplate 7, which is fixed to the top of frame 4;

[0047] The slide block 9 is slidably connected to the slide rail 6 on the front of the back plate 7 and is driven by the electric cylinder 8 fixed on the back plate 7. The slide block is driven by the electric cylinder on the slide rail of the back plate, providing stable and controllable linear motion, further ensuring the positioning accuracy and stability of the test probe in the process of approaching the slip ring.

[0048] The acquisition base 10 is fixed on the front of the slide 9, and the bottom of the acquisition base 10 is fixed with a motor 11.

[0049] And an adjustable detection component, which is driven by a motor 11, and the data collected by the adjustable detection component is transmitted to the detection system in the acquisition base 10.

[0050] In this embodiment, the adjustable detection component consists of a cap shell 13, detection elements, and a driving mechanism. Multiple detection elements are installed in a circumferential array on the inner wall of the cap shell 13, and each detection element is driven by the driving mechanism fixed inside the cap shell 13 to move synchronously outward or inward.

[0051] In this embodiment, the driving mechanism includes:

[0052] The cylinder 12 is fixed on the inner top surface of the cap 13, and the side wall of the cylinder 12 has a circumferential array of grooves the same number as the number of the test pieces.

[0053] The drive arm assembly has the same number of slots as the slide slots and is slidably connected to its corresponding slide slot;

[0054] And a push cylinder, which is fixed inside the cylinder 12, with the drive end of the push cylinder connected to the drive part of each drive arm assembly.

[0055] In this embodiment, a tapered plug 14 is slidably connected to the bottom of the cylinder 12, and a compression spring is connected between the plug 14 and the cylinder 12. The tapered plug 14 can adapt to slip rings with various inner diameter specifications. When the detection piece contacts the surface of the slip ring, the compression spring provides initial buffer for the tapered plug 14.

[0056] In this embodiment, the detection element includes:

[0057] The adjusting rod 16 has multiple telescopic rods with equal intervals connected between its top and the inner wall of the cap 13, and each telescopic rod has a spring 21 connected between its inner rod and outer rod.

[0058] And a roller-type detector 15, of which multiple are provided and are evenly rotatably mounted on the bottom of the adjusting rod 16;

[0059] Each roller detector 15 has multiple balls rolled on its wheel surface.

[0060] Specifically, the ball bearing design at the bottom of the detector transforms the contact point into rolling friction, greatly reducing frictional resistance and wear caused by relative motion, and can adapt to various detection contact methods, ensuring the accuracy of test data under real rotation conditions.

[0061] In this embodiment, the drive arm assembly includes:

[0062] The diagonal brace 23 is inclined and rotatably connected between the cylinder 12 and the adjusting rod 16;

[0063] The slider 18 is matched and slidably disposed in the groove. The outer side of the slider 18 is fixed with an ear seat 19. A push-pull rod 20 is rotatably connected between the ear seat 19 and the middle part of the diagonal brace 23.

[0064] And a baffle 17, which is disposed inside the cylinder 12 and fixedly connected to the slider 18, and the slider 18 is driven by a push cylinder;

[0065] Specifically, the telescopic rod between the adjusting rod and the cap and its internal spring enable each roller detector to independently make slight up-and-down movements when contacting the slip ring surface, automatically adapting to the slight height difference or unevenness that may exist in the slip ring contact track, maintaining a relatively constant contact pressure, and ensuring the stability and reliability of signal acquisition.

[0066] Furthermore, all telescopic rods are designed for directional telescopic movement to ensure that the movement path of the adjusting rod is always in a straight line;

[0067] It should also be noted that the push cylinder, through the linkage mechanism consisting of the drive plate, slider, ear seat, push-pull rod and diagonal brace, can synchronously drive each test component (adjusting rod and roller) to move radially inward or outward, thereby achieving rapid and automatic adaptation to the contact ring of conductive slip rings of different diameters. There is no need to replace the probe or make complicated manual adjustments, realizing "one-click switching" of the test object size, which significantly improves the test flexibility and efficiency.

[0068] In this embodiment, the outer diameter of the baffle 17 is larger than the width of the groove opening.

[0069] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
