[0033] Slip rings, also known as rotary electrical interfaces or electrical rotary joints, are commonly used in high-end industrial electrical equipment or precision electronic devices that require multi-function, high performance, high precision, and multiple continuous rotational motion. The quality of slip rings directly affects the lifespan and performance of motors, and the circular runout of slip rings is a key indicator for evaluating their quality.

[0034] Currently, the circular runout of slip rings is usually detected using a laser interferometer or a laser rotation detector, both of which utilize the interference phenomenon of laser beams for detection. However, due to the high cost of laser interferometers, the cost of slip ring detection remains high.

As an example, the mounting portion 6 is connected to the base 1 by a screw, and a gasket 12 is arranged on the screw head and pressed against the base 1, but is not limited thereto.

[0040] Continuing to refer to the drawings, in the present embodiment, the mounting portion 6 includes a connecting column, the bottom end of the connecting column is fixed to the top surface of the disc body 5, and the top end is used to support the slip ring 2.

[0041] As an example, the connecting column and the slip ring 2 can be connected by a fastener, but are not limited thereto. Specifically, a threaded hole is arranged on the connecting column, a connecting portion 21 is arranged on the slip ring 2, the connecting portion 21 is provided with a connecting hole, and a fastener 11 with external threads is inserted into the connecting hole and screwed into the threaded hole, so that the slip ring 2 can be connected to the mounting portion 6, but is not limited thereto.

[0042] In order to improve the installation convenience of the fastener 11, the top of the fastener 11 is provided with a torx handle, which is convenient for gripping and rotating the fastener 11, but is not limited thereto. In the present embodiment, the mounting portion 6 further includes a positioning column pressing plate 10 arranged above the connecting portion 21, which presses the connecting portion 21 through the positioning column pressing plate 10, so that the circumferential stress of the connecting portion 21 is uniform, and the safety and reliability of the detection link of the slip ring 2 are improved. As an example, the positioning column pressing plate 10 is pressed against the top of the connecting portion 21, but is not limited thereto.

[0043] As an example, the disc body 5 provided by the present disclosure is generally in the shape of an equilateral triangle, and the three mounting portions 6 are arranged at equal angles on the three corners of the equilateral triangle.

[0044] Continuing to refer to Figure 1 and Figure 2 , the detection unit 14 is described by taking an example of a dial gauge, but is not limited thereto. The detection unit 14 can also be a reading device, the detection head 13 is connected to the reading device, the detection head 13 is used to detect the circular runout of the slip ring 2, and the reading device can display the detection value of the detection head 13 to the user, thereby improving the use convenience of the detection unit 14.

[0045] In order to improve the reliability of the detection device for detecting the circular runout of the slip ring, a plurality of detection units 14 are provided, and the plurality of detection units 14 are arranged at equal angular intervals around the rotation axis. The circular runout of the slip ring 2 can be detected simultaneously by the plurality of detection units 14, thereby reducing the test error of a single detection unit 14 and improving the reliability of the detection device.

[0046] In this embodiment, in order to improve the installation convenience of the detection unit 14, the detection device also includes a magnetic fixing plate 7, which is connected to at least one of the base 1 and the base of the detection unit 14, so that the detection unit 14 is connected to the base 1 through magnetic attraction.

[0047] As an example, the base 1 and the base of the detection unit 14 can be composed of magnetic parts. For example, but not limited to, by setting the magnetic fixing plate 7 between the base 1 and the detection unit 14, the base 1 and the detection unit 14 can be respectively adsorbed on the magnetic fixing plate 7 by magnetic force, so that the detection unit 14 is firmly adsorbed on the base 1 by magnetic force, but not limited to this.

[0048] As needed, one of the base 1 and the base of the detection unit 14 can be a magnetic part, and the other can be a non-magnetic part. The magnetic fixing plate 7 can be connected to the non-magnetic part by gluing, fastener connection, etc., and then the magnetic part and the magnetic fixing plate 7 are connected by magnetic force, so that the detection unit 14 is firmly adsorbed on the base 1 by magnetic force, which is all within the protection scope of the present disclosure.

[0049] In an optional embodiment, when both the base 1 and the base of the detection unit 14 are non-magnetic parts, magnetic fixing plates 7 are connected to the base 1 and the base of the detection unit 14 respectively, and the two magnetic fixing plates 7 are adsorbed to each other by magnetic force, so that the detection unit 14 is firmly adsorbed on the base 1 by magnetic force, which is within the scope of protection of the present disclosure.

[0050] In this embodiment, there are four magnetic fixing plates 7, which are pre-installed on the base 1 respectively. The base of the detection unit 14 includes a magnetic member, and the base of the detection unit 14 can be connected to the magnetic fixing plates 7 by magnetic attraction.

The connecting shaft 4 is connected to the support plate 15, and the connecting shaft 4 is connected to the base 1 through the bearing 3, so that the connecting shaft 4 can rotate relative to the base 1.

[0052] Specifically, the top end of the connecting shaft 4 is connected to the disk body 5, the stator of the bearing 3 is connected to the base 1, and the rotor of the bearing 3 is connected to the connecting shaft 4, for example, but not limited to, to the bottom end of the connecting shaft 4. By connecting the bearing 3 between the connecting shaft 4 and the base 1, the connecting shaft 4 can rotate freely relative to the base 1. Since the disk body 5 is connected to the connecting shaft 4, during the process of the connecting shaft 4 rotating relative to the base 1, the disk body 5 can rotate relative to the base 1 along with the connecting shaft 4. In this embodiment, the rotation axis of the bearing 3 is also the rotation axis of the disk body 5, which is also the rotation axis of the support disk 15. The bearing 3 is well adapted to high-precision rotational motion and can maintain high-precision rotational motion even when pressure is applied.

[0053] As an example, the bearing 3 comprises a cross-roller bearing, which has low friction resistance, high precision, and a long structural service life, but the present invention is not limited thereto. As an example, the connecting shaft 4 provided in this embodiment is used in conjunction with the bearing 3, so that the connecting shaft 4 forms a high-precision connecting shaft, thereby improving the detection accuracy of the detection device.

[0054] When the slip ring 2 needs to be inspected, the slip ring 2 can be first mounted on the mounting portion 6 using the fasteners 11. Then, the support plate 15 can be driven to rotate relative to the base 1 about the rotation axis, thereby driving the slip ring 2 to rotate relative to the base 1. During the rotation of the slip ring 2, the detection head 13 of the detection unit 14 detects the circular runout parameters of the slip ring 2 in real time and can display them on a readout device.

[0055] In order to further improve the reliability of the detection device, the detection device also includes a plurality of leveling feet 9, which are connected to the bottom of the base 1 and are adjustable in the height and length directions of the base 1 to keep the base 1 on the same horizontal plane, thereby improving the reliability of the detection.

Since the detection device includes a base 1 and a support plate 15 rotatably connected to the base 1, when a slip ring 2 is mounted on the support plate 15, the support plate 15 can be rotated to drive the slip ring 2 to rotate, and the circular runout of the slip ring 2 can be detected by the detection unit 14. Operation is simple, convenient, and reliable.
