In one embodiment, a damping member 120 is provided at the press-fitting station; the damping member 120 includes a pressing piece 121 and an elastic member 122; the pressing block 121 is slidably arranged in a direction perpendicular to a first horizontal direction, in the first horizontal direction, two ends of the pressing block 121 are provided with guide angles 1211, and the two guide angles 1211 are distributed in a shape of a Chinese character 'ba'; the elastic member 122 is used for driving the pressing block 121 to move into the conveying trough 110 so as to increase the movement resistance of the turbine 1000 in the conveying trough 110. The movement resistance of the turbine 1000 is increased through the damping part 120, so that the situation that the position of the turbine 1000 at a press-fitting station is deviated due to too high speed when the pushing mechanism 200 transfers the turbine 1000 from one station to another station, and the electric brush cannot be installed in the installation groove 1010 is avoided. It can be understood that when the damping member 120 is not provided, one end of the pushing claw 230 facing the turbine 1000 may be provided with a U-shape or a V-shape, that is, the turbine 1000 is clamped by the U-shape or the V-shape, so as to avoid the position of the turbine 1000 in the press-fitting station from being shifted.
The elastic member 122 may be implemented by a spring or the like.
The top wall of the guide groove is provided with a vertical sliding groove; the sliding groove is in sliding fit with the pressing block 121. A limiting structure is arranged between the sliding groove and the pressing block 121 to limit the downward movement distance of the pressing block 121. The limiting structure can be realized by adopting the existing pin structure of the strip hole 231, and in the embodiment, the pressing block 121 and the sliding groove are both in a step shape with a large upper part and a small lower part, so that the limiting purpose is achieved by the steps of the pressing block 121 and the sliding groove.
By providing the guide angle 1211, the turbine 1000 can be smoothly introduced between the pressing piece 121 and the wall of the guide groove.
The invention is not limited to the above alternative embodiments, and any other various forms of products can be obtained by anyone in the light of the present invention, but any changes in shape or structure thereof, which fall within the scope of the present invention as defined in the claims, fall within the scope of the present invention.
