Abstract
Description
Technical Field
[0001] The invention relates to the technical field of semiconductor processing, in particular to a built-in brush holder slip ring structure. Background Art
[0002] Brush holder slip ring is the most widely used slip ring for conducting electricity in all slip ring series, also known as brush, carbon brush, collector ring, collector ring, collector ring, swivel, rotary electrical joint, dedicated to the transmission of power supply and signal power supply during unlimited continuous rotation. The brush holder slip ring as a whole mainly relies on the principle of elastic lap joint, attached to the infinitely rotating equipment, to provide power energy to the rotating body, but the existing brush holder slip ring is set on the outer ring of the copper ring, resulting in a high manufacturing cost. In order to reduce the manufacturing cost of the brush holder slip ring, we need a built-in brush holder slip ring structure.
[0003] In the brush holder slip ring currently used, the brush holder and the brush wire are arranged on the outer ring of the copper ring, so that the overall diameter of the slip ring is larger during manufacturing, and the length of the brush wire is longer, resulting in an increase in the manufacturing cost of the slip ring. Summary of the invention
[0004] The object of the present invention is to provide a built-in brush holder slip ring structure to solve the problems raised in the above background technology.
[0005] To achieve the above object, the present invention provides the following technical solutions:
[0006] A built-in brush holder slip ring structure comprises a stator rear end cover, a stator support rod is installed on the inner wall of the stator rear end cover, a double-sided insulating sheet is installed on the inner side wall of the stator rear end cover, a copper ring is installed on the inner wall of the double-sided insulating sheet, a single-sided insulating sheet is installed on the outer wall of the double-sided insulating sheet, a stator front end cover is installed on the bottom outer wall of the stator support rod, a rotor front end cover is installed on the inner wall of the stator front end cover, a brush holder is installed on the outer wall of the rotor front end cover, brush wires are installed on the inner wall of the brush holder, and the rotor rear end cover is installed on the outer wall of the brush holder away from the rotor front end cover.
[0007] Preferably, the stator rear end cover is threadedly connected to the stator support rods, and the stator support rods are distributed in a ring array with the central axis of the stator rear end cover as the center.
[0008] Preferably, the double-sided insulating sheet and the single-sided insulating sheet are both tightly fitted to the copper ring, and the double-sided insulating sheets are distributed at equal intervals with the central axis of the stator support rod as the center.
[0009] Preferably, the brush wires are symmetrically arranged with respect to the central axis of the brush holder, and the brush wires fit tightly with the copper ring.
[0010] A built-in brush holder slip ring structure comprises the following steps:
[0011] S1. Place the copper ring inside the double-sided insulation sheet and the single-sided insulation sheet for clamping and fixing, and then clamp and fix the double-sided insulation sheet and the single-sided insulation sheet through the stator rear end cover and the stator front end cover;
[0012] S2. Connect the stator rear end cover and the stator front end cover by threading through the stator support rod to provide limited support to prevent the double-sided insulation sheet, the single-sided insulation sheet and the internal copper ring from shaking and falling off, thereby improving the installation stability of the copper ring;
[0013] S3, the rear end cover of the rotor is connected with the rear end cover of the stator by snapping, and then the brush holder is installed on the outer wall of the rear end cover of the rotor, and then the position of the brush holder is moved and adjusted so that the brush wire fits tightly with the copper ring;
[0014] S4, then engage the rotor front cover with the stator front cover, and penetrate the rotor front cover, the brush holder and the rotor rear cover with bolts to fix them in position;
[0015] S5. Finally, the brush wire is energized to provide power energy for the copper ring, completing the installation and use of the built-in brush holder slip ring structure.
[0016] Compared with the prior art, the present invention has the following beneficial effects:
[0017] By adopting the set brush holder and brush wire, the overall structure of most brush holder slip rings on the market is that the brush wire contacts the outer ring of the copper ring for electrical conduction. When the copper ring needs to be made larger due to structural reasons, the length of the brush wire needs to be increased, resulting in an increase in the manufacturing cost of the slip ring. When the number of slip rings is large, the cost increase problem is more serious. In addition, because the brush wire contacts the outer ring of the copper ring for electrical conduction, the brush holder needs to be installed on the periphery of the copper ring, and a mounting position for the brush holder needs to be reserved, thereby further increasing the overall diameter of the slip ring. The present invention adopts the method of contacting the inner ring of the copper ring with the brush wire for electrical conduction, which can not only reduce the length of the brush wire, but also does not need to increase the overall diameter of the slip ring, making the internal structure of the slip ring more compact and greatly reducing the manufacturing cost of the slip ring.
