The clamping driver 2 is fixed to the bracket 1, and the clamping driver 2 is located on the back of the back plate 1a and is fixed to the back plate 1a. When the lifting drive mechanism and the first driver B are working, the clamping driver 2 located on the back of the back plate 1a can avoid interference with the lifting drive mechanism and the first driver B. The clamping driver 2 preferably uses a finger cylinder, one end of the clamping arm 3 is fixed to the clamping driver 2, and the other end of the clamping arm 3 is fixed to the clamping block 4.

[0025] The clamping arm 3 includes a first connecting segment 3a, a second connecting segment 3b, and a third connecting segment 3c. The two ends of the second connecting segment 3b are respectively fixed to the first connecting segment 3a and the third connecting segment 3c. A first angle is formed between the second connecting segment 3b and the first connecting segment 3a, and a second angle is formed between the second connecting segment 3b and the third connecting segment 3c. Both the first angle and the second angle are 90°. After the clamping arm 3 adopts the above structure, a part of the clamping arm 3 extends to the front of the front of the back panel 1a, so that the clamping mechanism, the lifting drive mechanism and the first driver B are reasonably distributed.

[0026] The lifting drive mechanism is connected to the bracket 1, and the first driver B is connected to the lifting drive mechanism. The lifting drive mechanism includes a lifting driver 5 and a lifting mounting seat 6. The lifting driver 5 is fixed to the bracket 1, and the lifting mounting seat 6 cooperates with the lifting driver 5. The first driver B is fixed to the lifting driver 5. The lifting driver 5 is a linear driver, and the lifting driver 5 can adopt a linear driver such as a cylinder, a hydraulic cylinder, and an electric linear module. The lifting mounting seat 6 is composed of a vertical mounting plate 6a and a horizontal mounting plate 6b. The vertical mounting plate 6a is fixed to the horizontal mounting plate 6b, and a 90° angle is formed between the vertical mounting plate 6a and the horizontal mounting plate 6b. The vertical mounting plate 6a is fixed to the lifting driver 5, and the first driver B is fixed to the horizontal mounting plate 6b.

[0027] The toggle assembly is connected to the power output end of the first driver. The toggle assembly includes a first toggle assembly and a second toggle assembly. The first toggle assembly is fixed to the lifting drive mechanism, and the second toggle assembly is fixed to the first driver. When the brush holder assembly A is matched with the positioning column 10, the brush C forms an empty sleeve for the first toggle assembly. When the lifting drive mechanism descends, the second toggle assembly descends along with the lifting drive mechanism, and the second toggle assembly is inserted into the inner hole on the brush C.

[0028] The first toggle assembly and the second toggle assembly both include a paddle mounting seat 7a and a paddle 7, and the paddle 7 is fixed to the paddle mounting seat 7a.

[0030] The paddle 7 is in a straight line shape, and this design can reduce the amount of materials used while maintaining sufficient strength and rigidity. At the same time, the cover plate 8 and the paddle mounting seat 7a are used as two parts, which can reduce the number of repeated clamping during the processing, and reduce the welding, drilling and other processes during the processing, greatly reducing the production cost, production difficulty and production cycle of its spare parts.

[0031] The cover plate 8 is screwed together with the paddle 7 and the paddle mounting seat 7a. The three parts are installed by overlapping and screwing. This design can realize quick replacement in a limited space, reduce the time required for tooling replacement, and thus reduce production losses.

[0032] The support plate 9 is fixed to the bracket 1, one end of the positioning column 10 is fixed to the support plate 9, and the other end of the positioning column 10 is provided with a latch 11 for matching with the hole on the brush holder assembly A, and there is a step between the latch 11 and the positioning column 10. A clearance notch 9a is provided on the support plate 9, and the clearance notch 9a matches with the first driver B.

[0033] The working process of the present invention is as follows: The operator matches the brush holder assembly A pre-installed with the brush C with the latch 11, that is, the hole on the brush holder assembly A matches the latch 11, and the axial end face of the brush holder assembly A abuts against the step between the latch 11 and the positioning column 10, so that the brush holder assembly A obtains axial positioning, and the brush C forms an empty sleeve for the first toggle assembly. At this time, the operator applies a supporting force to the brush holder assembly A. Subsequently, the operator starts the clamping driver 2, which drives the clamping arm 3 and the clamping block 4 to move, so that the clamping block 4 clamps the brush holder assembly A. The operator starts the lifting driver 5, which drives the lifting mount 6 to descend, and the first driver B and the second toggle assembly descend with the lifting mount 6. During this process, the second toggle assembly is inserted into the inner hole on the brush C. The operator starts the first driver B, which drives the second toggle assembly to move, and the second toggle assembly drives the brush C to move, so that the brush C and the brush holder assembly A are combined in a predetermined direction. When the brush C hits the first toggle assembly, the first driver B stops working. At this time, the brush C and the brush holder assembly A are combined in place, and the combination in place can be detected by the distance measuring sensor.
