Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of conductive slip ring debugging, and specifically relates to a brush wire elbow tool. BACKGROUND

[0002] The conductive slip ring is a precision power transmission device for realizing power and signal transmission between two relative rotating mechanisms, and is widely applied to robots, intelligent production lines, radar systems and the like. Figure 1 The conductive slip ring is divided into a rotating part and a stationary part, and the rotating part and the stationary part are driven by a mechanical interface to generate relative rotary motion, thereby realizing n±360° unlimited rotation of the rotating part and the stationary part. Figure 2 The working principle of the conductive slip ring is as follows: the conductive slip ring is supported by bearings at the rotating part and the stationary part to form n±360° unlimited rotation, and power and signal transmission between the rotating part and the stationary part is realized by relying on the friction pair between the rotating part and the stationary part. Figure 3

[0003] The brush wire, as one of the friction pairs of the conductive slip ring, is in one-to-one correspondence with the ring groove of the other friction pair, the conductive ring, in perpendicular or other angle point contact; during the operation of the conductive slip ring, the brush wire only has one point of contact in one rotation, while the conductive ring has multiple points of contact in the form of a circular ring, so the brush wire is more worn out; considering the service life of the friction pair, the hardness of the brush wire is usually higher than that of the conductive ring; when the brush wire is cut, the cutting edge is relatively sharp, and the sharp part may cut the surface of the conductive ring during operation, greatly increasing the wear; therefore, the end of the contact point needs to be bent to avoid scratching the surface of the conductive ring, and the bending process is prone to cause the brush wire to be deformed and skewed; the skew of the brush wire reduces the service life of the friction pair, reduces the reliability of the conductive slip ring, and has the risk of short-circuiting and burning out the equipment, and after the brush wire is bent, it is difficult to observe and adjust the alignment of the brush wire by the naked eye due to the inconsistent left and right deflection of each elbow.

[0004] In order to solve the above problems, the utility model provides a brush wire elbow tool.

[0005] The utility model provides the following technical scheme:

[0006] A brush wire elbow tool, comprising a positioning assembly and a brush assembly, characterized in that the positioning assembly comprises a positioning strip, a pressing plate and a screw.
