The side of the brushing plate 31 away from the tool base 1 is provided with a first concave accommodating chamber 312 for accommodating the bearing groove 42 of the motor end cover 4. The edge welding of dialling brush dish 31 has two and dials brush dish 31 and keep away from frock base 1 one side vertically and dial brush needle 313 for wear to establish in the arc hole 44 of motor end cover 4, when dialling brush dish 31 and rotate, dial brush needle 313 and be used for promoting brush piece 41, realize dialling the brush effect. In order to make the pushing forces of the two brushing needles 313 on the brush piece 41 tend to be equal and reduce the damage of the brush piece 41, the brushing needles 313 in the embodiment are symmetrically arranged on the brushing plate 31.

Referring to fig. 3, two second avoiding holes 212 are symmetrically formed in a surface of the positioning column 21 away from the tool base 1, and the second avoiding holes 212 are located at the periphery of the brushing needle 313. When the motor end cover 4 is placed on the poking brush assembly tool in the embodiment, the two second hiding holes 212 are used for hiding the terminals 45 on the motor end cover 4, so that the collision damage of the tool to the terminals 45 is reduced. The positioning column 21 is further provided with a positioning block 213 for being inserted into the positioning hole 46 of the motor end cover 4 in an embedded manner, so that the motor end cover 4 is not easy to rotate when the brush is pulled. One surface of the positioning column 21 away from the tooling base 1 is provided with a second accommodating chamber 214 for accommodating the whole motor end cover 4, and the second accommodating chamber 214 is also concave.

Referring to fig. 4, the motor end cover 4 includes two brush sheets 41 located inside the motor end cover 4, the two brush sheets 41 are respectively and fixedly connected with a carbon brush 411, a bearing groove 42 is formed in the center of the motor end cover 4, the bearing groove 42 is used for placing a bearing coaxially fixed on an output shaft of the motor rotor, a mounting hole 43 through which the output shaft of the motor rotor penetrates is formed in the bearing groove 42, and the mounting hole 43 and the bearing groove 42 are formed in a concentric manner. Two arc holes 44 are symmetrically formed along the circumferential direction of the bearing groove 42, so that the brushing pulling needle 313 in the embodiment can be conveniently penetrated and moved, and the brushing pulling needle 313 can be conveniently used for brushing. Two terminals 45 are mounted on the side of the motor end cover 4 facing away from the two brush pieces 41, and two positioning holes 46 are formed in the side of the motor end cover 4 facing away from the two brush pieces 41, wherein the positioning holes 46 are blind holes, so that the motor end cover 4 can be conveniently placed on the positioning block 213 in the embodiment.

Referring to fig. 1, in order to facilitate accurate reset after the control rod 32 is pushed out, a mounting part 11 is disposed on one side wall of the tooling base 1 in the embodiment, which is close to the control rod 32, specifically, the mounting part 11 is a bolt fixed to the tooling base 1 by a thread, a reset spring 321 is connected to the mounting part 11, and one end of the reset spring 321, which is far away from the mounting part 11, is connected to one end of the control rod 32, which is far away from the rotating column 33. When the control lever 32 is pushed out, the return spring 321 tends to pull back the control lever 32 by its own elasticity.

The implementation principle of the above embodiment is as follows: when the brushing tool for the motor end cover 4 in this embodiment is used, the positioning hole 46 on the motor end cover 4 faces the positioning block 213 on the positioning column 21, and after the two arc-shaped holes 44 on the motor end cover 4 face the brushing needle 313 on the brushing disk 31, the motor end cover 4 is placed in the second accommodating chamber 214. When the motor end cover 4 is placed in the second accommodating chamber 214, the two brushing poking needles 313 respectively penetrate through the arc-shaped holes 44, the positioning blocks 213 on the positioning columns 21 are embedded into the positioning holes 46 of the motor end cover 4, the bearing grooves 42 and the terminals 45 on the motor end cover 4 are respectively located in the first accommodating chamber 312 and the second avoiding hole 212 on the tool, at this time, the user pushes the control rod 32, so that the rotating column 33 drives the brushing poking disc 31 to rotate, the two brushing poking needles 313 rotate in the arc-shaped holes 44 along with the brushing poking disc 31 to generate thrust on the brush sheet 41, and the positioning blocks 213 limit the rotation of the motor end cover 4, so that the brush sheet 41 is easy to be poked gradually along with the increase of the rotation angle of the brushing poking needles 313.

After the two brush sheets 41 are pulled apart, the mounting hole 43 on the motor end cover 4 is exposed, the user can pass the output shaft of the motor rotor through the mounting hole 43 and make the output shaft continuously pass through the first hiding hole 311 until the bearing of the motor rotor is mounted in the bearing hole of the motor end cover 4, the user can gradually release the force applied on the control rod 32 to reset the control rod 32, so that the carbon brushes 411 on the two brush sheets 41 are abutted to the output shaft of the motor, at this time, the motor end cover 4 combined on the motor rotor can be taken down from the positioning column 21, and the combination of the motor end cover 4 and the motor rotor is completed.

The embodiment of this specific implementation mode is the preferred embodiment of the present invention, not limit according to this the utility model discloses a protection scope, so: all equivalent changes made according to the structure, shape and principle of the utility model are covered within the protection scope of the utility model.
