Description

Technical Field

[0001] This utility model relates to the field of conductive slip ring assembly, and more specifically, to a slip ring positioning fixture. Background Technology

[0002] Conductive slip rings belong to the category of electrical contact sliding connections. They are also known as slip rings, rotary joints, rotary electrical interfaces, conductive slip rings, current collectors, return rings, coils, commutators, and adapters. They are precision power transmission devices that realize the transmission of image, data signals, and power between two relatively rotating mechanisms.

[0003] When the brush assembly in the conductive slip ring rotates, the brush slides into contact with the grooves of the conductive ring, thus maintaining stable current conduction or signal transmission during rotation. To improve reliability, the positions of the brush contacts and the grooves on the conductive ring are designed to correspond one-to-one. However, when manually assembling large-sized or multi-loop conductive rings, the ring may be too long or too large, requiring someone to support it. Utility Model Content

[0004] The purpose of this utility model is to provide a ring positioning tool to solve the technical problems existing in the background art.

[0006] The chuck structure includes a chuck body and three sets of jaw structures slidably connected to the chuck body. Each jaw structure includes a jaw seat and a rubber buffer member disposed at the front end of the jaw seat. The rubber buffer member is detachably connected to the jaw seat. Both the chuck body and the mounting base plate are hollow annular structures, and the support portion of the support structure is located in this hollow area.

[0007] In a preferred embodiment, the rubber buffer includes a snap-fit ​​portion and a clamping portion integrally formed with the snap-fit ​​portion. The clamping portion includes arc-shaped outward protrusions on both sides and an arc-shaped inward concave portion in the middle. When clamped, the arc-shaped inward concave portion in the middle contacts the conductive ring.

[0008] In a preferred embodiment, the arc-shaped concave portion is provided with a wavy protrusion.

[0009] In a preferred embodiment, the snap-fit ​​portion is provided with snap-fit ​​protrusions, and the snap-fit ​​claw seat is provided with snap-fit ​​grooves on both sides, with the snap-fit ​​protrusions inserted into the snap-fit ​​grooves.

Detailed Implementation

[0019] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments. The embodiments of the present invention are given for the purpose of illustration and description, and are not intended to be exhaustive or to limit the present invention to the disclosed forms. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described to better illustrate the principles and practical applications of the present invention, and to enable those skilled in the art to understand the present invention and design various embodiments with various modifications suitable for a particular purpose.

[0020] like Figures 1-3As shown, this utility model provides a ring positioning fixture, including a bracket 1, a mounting base plate 2 disposed on the bracket 1, a chuck structure mounted above the mounting base plate 2, and a support structure 14 mounted below the mounting base plate 2. The chuck structure clamps the conductive ring, facilitating subsequent assembly work without requiring manual support.

[0021] The chuck structure includes a chuck body 3 and three sets of jaw structures 4 slidably connected to the chuck body 3. Each jaw structure 4 includes a jaw seat 5 and a rubber buffer 6 disposed at the front end of the jaw seat 5. The rubber buffer 6 is detachably connected to the jaw seat 5. Both the chuck body 3 and the mounting base plate 2 are hollow annular structures, and the supporting part of the support structure is located in this hollow area.

[0022] The drive module on the chuck body 3 can drive three sets of jaw structures 4 to move simultaneously in directions of approach or distance from each other. During movement, the movement is limited by guide rails on the chuck body 3. The drive structure is an existing structure, such as the drive structure commonly used in three-jaw chucks. A conductive ring is located between the three sets of jaw structures 4. When the jaw seat 5 moves, its rubber buffer 6 approaches the conductive ring, ultimately clamping the conductive ring. The rubber material provides a certain degree of cushioning, preventing damage to the conductive ring.

[0023] This design incorporates three sets of clamping claw structures 4. The clamping distance of these structures can be adjusted to secure conductive rings of different sizes. Furthermore, the conductive rings exit from the hollow area, eliminating the need to re-organize the wiring each time they are assembled, thus reducing assembly time. The bottom support structure 14 provides support and initial positioning for the conductor rings before clamping, ensuring they remain upright after clamping.

[0024] The rubber buffer 6 includes a snap-fit ​​part 7 and a clamping part 8 integrally formed with the snap-fit ​​part 7. The snap-fit ​​part 7 connects to the claw seat 5, and the clamping part 8 clamps the conductive ring.

[0025] The latching part 7 is provided with a latching protrusion 12, and the jaw seat 5 has latching grooves 13 on both sides. The latching protrusion 12 is inserted into the latching groove 13. The latching groove 13 is an isosceles trapezoid, and the latching protrusion 12 is adapted to the shape of the latching groove 13. The protrusion of the latching part 7 can be inserted into the latching groove 13 on the jaw seat 5 to fix the two. When the clamping part 8 is worn or the diameter of the clamped conductive ring is significantly different, the rubber buffer 6 can be replaced as a whole to meet the clamping requirements. Moreover, the latching groove 13 and the latching protrusion 12 adopt a trapezoidal structure to ensure the latching is firm, prevent the rubber buffer 6 from falling off, and facilitate replacement.

[0026] The clamping part 8 includes arc-shaped outward protrusions 9 on both sides and an arc-shaped inward concave part 10 in the middle. During clamping, the arc-shaped inward concave part 10 in the middle contacts the conductive ring. The arc-shaped inward concave part 10 is provided with wavy protrusions 11. By providing the arc-shaped inward concave part 10 and the wavy protrusions 11 on its surface, the fit with the outside of the conductive ring is ensured, and the clamping is secure. The arc-shaped outward protrusions 9 on both sides will not interfere with the clamping of the arc-shaped inward concave part 10.

[0027] The support structure 14 is arranged in three groups in a circumferential direction. Each support structure 14 includes a mounting bracket 15 and a support plate 16 mounted on the mounting bracket 15. The support plate 16 is detachably connected to the mounting bracket 15. The support plate 16 supports the bottom of the conductive ring. Before fixing, the support plate 16 ensures the conductive ring is upright, guaranteeing that it remains upright after clamping and preventing tilting from affecting subsequent ring assembly.

[0028] Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art and related fields based on the embodiments of this utility model without creative effort should fall within the protection scope of this utility model. Structures, devices, and operating methods not specifically described and explained in this utility model, unless otherwise specified or limited, shall be implemented according to conventional means in the art.
