Description

Technical Field

[0001] This invention relates to a method for adjusting brush filaments, and more particularly to a method for adjusting brush filaments of a large-angle conductive slip ring. Background Technology

[0002] A slip ring is a device used to transmit electrical power and signals. Its working principle involves the precise transmission of electrical signals between the stationary and rotating parts of the slip ring through relative rotation. As the stator part of the slip ring, the consistency of the brush filament angle directly affects the stability of electrical transmission. With continuous optimization and changes in the design of slip rings, the requirement for large brush filament angles has emerged. Previous brush filament adjustment methods used brush filament angle fixtures, with the brush filament forming angle being the filament angle. However, due to the space limitations of the slip ring, and the fact that current brush filament angle fixtures are not convenient for adjusting large-angle brush filaments, it is difficult to guarantee the adjustment of large-angle brush filaments. Therefore, large-angle brush filaments are difficult to form at the correct brush filament angle. Currently, a right-angle forming method is generally used, forming the brush filament after it passes through the brush positioning plate. During this process, the large-angle brush filaments may undergo elastic deformation during later use, recovering some of the pre-deformation, thus making it difficult to guarantee the consistency of the brush filament angle. Therefore, there is an urgent need for a large-angle brush bristle adjustment method to meet the requirements of conductive slip rings. Summary of the Invention

[0003] The purpose of this invention is to provide a method for adjusting the bristles of a large-angle conductive slip ring that can better ensure the large angle and consistency of the bristle opening angle, for use in the adjustment of the large opening angle during the development of conductive slip rings.

[0004] The objective of this invention is achieved as follows:

[0005] A method for adjusting the filaments of a large-angle conductive slip ring, characterized by:

[0006] A. Tools required for debugging:

[0007] a. Angle Positioning Block: The angle positioning block is made of aluminum alloy. The irregularly shaped angle positioning block consists of a cuboid and a right-angled trapezoid block. The hypotenuse of the right-angled trapezoid block is used to place the brush bristles. The sum of the forming angle of the upper end of the right-angled trapezoid block and the angle of the four angles of the brush bristles is 90°. An angle positioning block positioning clip is provided on the top edge of the cuboid and behind the right-angled trapezoid block for connection with the brush assembly. A screw hole penetrating the front and back of the cuboid is provided on the upper front of the cuboid.

[0008] b. Brush bristle support rod: A cylindrical strip made of polyimide material;

[0009] c. Brush fixing plate: A square plate made of polyimide material, used to fix the brush filaments after the brush filaments are shaped and aged, so that the brush filaments can obtain permanent brush filament deformation.

[0010] B. The debugging steps are as follows:

[0011] a. Based on the lever principle, place the brush bristle support rod at the root of the brush bristles and fix it with adhesive. The brush bristle support rod should run through the entire brush assembly so that the brush bristles have a fulcrum.

[0012] b. The screw passes through the screw hole of the angle positioning block and the angle positioning block is installed on the brush assembly, so that the positioning edge of the angle positioning block is in contact with the positioning edge of the brush assembly.

[0013] c. Use the bristle fixing plate to bend the bristles until the bristles are in contact with the bevel of the angle positioning block;

[0014] d. Use 3M tape to bond the bristle fixing plate to the angle positioning block, at which point the bristles are located between the two.

[0015] e. Place the entire brush assembly and the brush bristles together in a high and low temperature chamber for high and low temperature aging.

[0016] f. Remove the brush bristle fixing plate, brush bristle support rod and angle positioning block, place the brush assembly vertically and allow it to age naturally.

[0017] g. The angle of the bristles was measured and found to be consistent. Glue was then applied to the base of the bristles.

[0018] In step e, the entire brush assembly and the brush bristle adjustment fixture are placed together in a high and low temperature chamber for 12-36 hours.

[0019] In step f, the brush assembly is placed vertically for 12-36 hours.

[0020] This invention employs an angle positioning block, a bristle support rod, and a bristle fixing plate. First, the bristle support rod is placed at the root of the bristles and fixed with adhesive. Then, the bristle positioning block is installed at the fixed position of the brush assembly. Next, the bristles are bent using the bristle fixing plate until the bristles are in contact with the bevel of the bristle positioning block. The bristle fixing plate is then bonded to the bristle positioning block using 3M tape. Finally, high and low temperature aging and natural aging are performed. After confirming that the bristle angle is consistent, adhesive is applied to the root of the bristles. In this way, the bristles can obtain a larger angle and ensure good consistency.

[0021] Therefore, compared with traditional debugging methods, the present invention has the advantages of convenient operation, one-time molding, and good consistency. Attached Figure Description
