[0019] The brush assembly is provided with a shearing auxiliary tool, such as Figs. 1-3 As shown, it comprises a body 2 which is adapted to the brush holder 1-1 groove in the brush assembly 1, and a plurality of guide grooves 3 are uniformly distributed on the side walls of the two long sides of the body 2 along the length direction, which are adapted to the brushes 1-2 in the brush assembly 1. The brushes 1-2 are installed in the corresponding guide grooves 3 and the upper end of the brush 1-2 protrudes out of the guide groove 3, and the shearing is carried out on the brush 1-2 protruding out of the guide groove 3 along the long side of the body 2 by a pair of scissors. In the above structure, under the premise that the body 2 is adapted to the groove of the brush holder 1-12, each brush 1-2 protrudes out of the corresponding guide groove 3 on the long side of the body 2, so that the position of the brush 1-2 is relatively determined, and the length size has a reference basis, which overcomes the problems of difficulty in fixing the brush assembly 1 and irregular shearing, improves the efficiency and meets the shearing requirements;

[0020] Wherein, the lower end of the body 2 is adapted to the groove in the middle of the brush holder 1-1, and the length of the body 2 is greater than the length of the groove of the brush holder 1-1; Specifically, the shape of the body 2 is determined according to the shape of the groove of the brush holder 1-1;

[0021] The specific structure of the body 2 is as follows: the body 2 adopts a base 2-1 which is adapted to the groove of the brush holder 1-1 and a plurality of superimposed plates 2-2 which are positioned and superimposed in order from bottom to top and integrated as a whole. The height of the body 2 is adjusted by increasing or decreasing the number of superimposed plates 2-2 according to the target length of the brush 1-2.

[0022] The superimposed connection structure of the base 2-1 and the superimposed plate 2-2 is as follows: a plurality of convex columns 2-3 are uniformly distributed on the upper end faces of the base 2-1 and the superimposed plate 2-2, positioning grooves corresponding to the positions of the convex columns 2-3 are formed on the bottom faces of the superimposed plate 2-2, the convex columns 2-3 on the base 2-1 are matched with the positioning grooves on the bottom faces of the bottommost superimposed plate 2-2, and two adjacent superimposed plates 2-2 are connected through the corresponding convex columns 2-3 and positioning grooves; by using the above structure, the superimposed plate 2-2 can be increased or reduced according to the length required by the brush 1-2 after shearing, that is, the target length, so as to meet the positioning requirements of shearing of brushes 1-2 of different lengths; the base 2-1 and the superimposed plate 2-2 are connected in a detachable superimposed manner, so that the height of the body 2 can be adjusted according to the length of the brush 1-2, thereby meeting the positioning and shearing requirements of brushes 1-2 of different lengths and increasing the positioning range.

[0023] Since the brush 1-2 is relatively soft, in order to avoid damage to the brush 1-2 by hard materials, the body 2 is supported by a copper strip or an aluminum strip.

[0024] When the product is manufactured, the shearing auxiliary is passed through the middle position of the brush assembly, so that each brush 1-2 can extend from the corresponding guide groove 3, and according to the height of the body 2, one person can independently complete the shearing work with the cooperation of scissors, and the flatness effect is good.

[0025] The technical solution has the advantages of simple structure, reasonable design, easy manufacturing, small size, practicality, small volume, low cost, and can effectively improve the qualified rate and production efficiency of the brush assembly assembly process of the power transmission device.
