Description

Technical Field

[0001] The present application relates to the technical field of conductive slip rings, and in particular to transmission structures of electric slip rings and optical fiber slip rings. Background Art

[0002] With the advancement of science and technology, ordinary electric slip rings are no longer able to transmit signals to meet market demand. Therefore, the use of fiber optic slip rings to transmit signals has become a trend. Since fiber optic slip rings cannot transmit current, a combination of fiber optic slip rings and electric slip rings is required. In the combination of fiber optic slip rings and electric slip rings, the most important part is the mechanical transmission structure.

[0003] The existing mechanical transmission structure is basically realized by using a fixed position method, as shown in the attached manual. Figure 4 As shown in the figure, the mechanical transmission plate is locked on the rotor of the electric slip ring, and the optical fiber slip ring is driven by the clamping position of the mechanical transmission plate. This fixed clamping method has extremely high requirements for processing accuracy and assembly accuracy. The processing itself must have dimensional tolerances, and the cumulative dimensional tolerances after assembly will be further expanded, resulting in a great risk in this mechanical transmission method. Figure 6-8 As shown in the figure, the locking flange of the mechanical transmission plate is locked in the locking groove of the fiber optic slip ring rotor. The dimensional tolerance of the two is within the range. Only after assembly can the fiber optic slip ring rotor not be blocked while ensuring synchronization. Once the dimensional tolerance exceeds the range or there is eccentricity after assembly, the rotor of the fiber optic slip ring will be compressed and blocked, and finally the transmission loss of the fiber optic slip ring will far exceed the standard value. Utility Model Content

[0004] The purpose of this application is to provide a transmission structure of an electric slip ring and an optical fiber slip ring to solve the technical problems raised in the above background technology.

[0005] To achieve the above objectives, the present application provides the following technical solution: a transmission structure of an electric slip ring and a fiber optic slip ring, comprising an electric slip ring body and a fiber optic slip ring connected inside the electric slip ring, wherein the electric slip ring body comprises an electric slip ring stator and an electric slip ring rotor rotatably connected to the outside of the electric slip ring stator, and the fiber optic slip ring comprises a fiber optic slip ring stator fixedly connected to the electric slip ring stator and a fiber optic slip ring rotor rotatably connected to the fiber optic slip ring stator, wherein the fiber optic slip ring rotor and the electric slip ring stator are connected via a locking driving portion.

[0006] In one embodiment, the locking driving part includes two mounting grooves symmetrically opened inside the electric slip ring rotor, two locking grooves symmetrically opened inside the optical fiber slip ring rotor, a plate body fixed in the mounting grooves, a groove body opened inside the plate body, a fixed shell fixed in the groove body, a spring and a ball arranged inside the fixed shell, and the two ends of the spring are respectively connected to the inner wall of the fixed shell and the outer surface of the ball, and an opening for the ball to extend out is opened on one side of the fixed shell.

[0007] In one embodiment, the plate is fixed in the mounting groove by bolts.

[0008] In one embodiment, the electric slip ring stator and the electric slip ring rotor are connected via a bearing.

[0009] In one embodiment, the optical fiber slip ring stator is fixed to the electric slip ring stator by screws.

[0010] Compared with the prior art, the present invention has the following advantages:

[0011] The present application adopts an elastic mechanical driving structure, in which the elastic force of the spring is greater than the torque of the optical fiber slip ring, and the elastic force of the spring is less than the pressure that causes the transmission loss to exceed the standard after the optical fiber slip ring is compressed. This structure greatly reduces the requirements for processing accuracy and assembly accuracy, while ensuring that the electric slip ring and the optical fiber slip ring rotate synchronously, and the optical fiber slip ring will not be compressed and blocked, resulting in excessive transmission loss. This effectively solves the problem of eccentricity between the optical fiber slip ring and the electric slip ring after assembly, and also ensures that the mechanical transmission of the optical fiber slip ring and the electric slip ring can be synchronized, which greatly reduces the requirements for processing technology and assembly. At the same time, while ensuring angular synchronization, the optical fiber slip ring will not be compressed and blocked, resulting in damage to transmission. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] Example:

[0024] See also Figure 1-8 The present application provides a technical solution: a transmission structure of an electric slip ring and a fiber optic slip ring, comprising an electric slip ring body 1 and a fiber optic slip ring connected to the electric slip ring body 1, wherein the electric slip ring body 1 comprises an electric slip ring stator 11 and an electric slip ring rotor 13 rotatably connected to the outside of the electric slip ring stator 11, and the fiber optic slip ring comprises a fiber optic slip ring stator 2 fixedly connected to the electric slip ring stator 11 and a fiber optic slip ring rotor 4 rotatably connected to the fiber optic slip ring stator 2, and the fiber optic slip ring rotor 4 is connected to the electric slip ring stator 11 via a locking driving portion 5.

[0025] The locking driving part 5 includes two mounting grooves 14 symmetrically provided inside the electric slip ring rotor 13, two locking grooves 41 symmetrically provided inside the optical fiber slip ring rotor 4, a plate body 51 fixedly connected to the mounting groove 14, a groove body 52 provided inside the plate body 51, a fixed shell 53 fixedly connected to the groove body 52, a spring 54 and a wave ball 55 provided inside the fixed shell 53, and the two ends of the spring 54 are respectively connected to the inner wall of the fixed shell 53 and the outer surface of the wave ball 55. An opening for the wave ball 55 to extend out is provided on one side of the fixed shell 53, and an elastic mechanical driving structure is adopted. The elastic force of the spring 54 is greater than the torsional moment of the optical fiber slip ring. The elastic force of the spring 54 is less than the pressure that causes the transmission loss to exceed the standard after the optical fiber slip ring is compressed. This structure greatly reduces the requirements for processing accuracy and assembly accuracy. At the same time, it ensures that the electric slip ring body 1 and the optical fiber slip ring rotate synchronously without causing the optical fiber slip ring to be compressed and blocked, resulting in excessive transmission loss. It effectively solves the problem of eccentricity between the optical fiber slip ring and the electric slip ring body 1 after assembly. At the same time, it also ensures that the mechanical transmission of the optical fiber slip ring and the electric slip ring body 1 can be synchronized, greatly reducing the requirements for processing technology and assembly. At the same time, while ensuring angular synchronization, the optical fiber slip ring will not be compressed and blocked, resulting in damage to transmission.
