Description
Technical field
The utility model belongs to mechanical & electrical technology field, specifically a kind of brushgear that is specifically designed to electric mill machine.
Background technology
At present, after small DC electric motor brush is installed, all that energising allows DC motor no-load running, make the contact-making surface nature break-in of brush and commutator, the advantage of the method is can intactly to contact with commutator face by brush after natural break-in, when proof load, normally move, but because of commutator face smoother, making brush grind one needs for a long time with the identical arc surface of commutator brush track diameter, sometimes need 2～3 days even for more time, so just increase the production cycle, reduced production efficiency, but also increased power consumption.
Summary of the invention
The technical problems to be solved in the utility model is that brush and commutator running-in time after installation of existing motor is longer, has increased production cycle and power cost.
In order to solve the problems of the technologies described above, the utility model provides a kind of electric mill brush device, comprise columniform friction piece, ring flange, drive motors, brush holder dish, spring leaf and brush carrier, the excircle of friction piece is coarse rubbing surface, and be removably mounted on the driving shaft of drive motors, one side of ring flange is arranged on drive motors, opposite side and brush holder dish are detachably installed, spring leaf and brush carrier mounted in pairs are on brush holder dish, spring leaf is positioned at the brush socket top of brush carrier, the just rubbing surface to friction piece of the brush socket of brush carrier.
The friction piece that employing has coarse rubbing surface rubs to brush, makes the brush just can break-in one-tenth within a few minutes and the identical cambered surface of commutator; Adopt friction piece is removably mounted on the driving shaft of drive motors, can conveniently follow according to the diameter of axle of commutator the friction pieces that change different sizes, make brush can meet the requirement of different radians; Adopt spring leaf can effectively control the pressure between friction piece and rubbing surface, improve the efficiency of break-in, also can meet the pressure demand of the friction piece of different size.
As further restriction scheme of the present utility model, in the installing hole of friction piece, be provided with friction piece keyway, the driving shaft of drive motors is provided with drive shaft keyways, and friction piece keyway and drive shaft keyways are detachably installed by fitting key.Adopt fitting key to realize the detachable installation between friction piece and driving shaft, the convenient friction piece with changing different size.
As further restriction scheme of the present utility model, spring leaf and brush carrier are four pairs, and are evenly arranged on the circumference of brush holder dish.Adopt four pairs and carry out simultaneously, further improved operating efficiency.
As further restriction scheme of the present utility model, ring flange is provided with the motor installing hole of installing mutually with drive motors, is also provided with the brush holder dish installing hole of installing mutually with brush holder dish.Adopt flange replacing easy to connect or dismounting brush holder dish.
The beneficial effects of the utility model are: (1) adopts the friction piece with coarse rubbing surface to rub to brush, make the brush just can break-in one-tenth within a few minutes and the identical cambered surface of commutator; (2) adopt friction piece is removably mounted on the driving shaft of drive motors, can conveniently follow according to the diameter of axle of commutator the friction pieces that change different sizes, make brush can meet the requirement of different radians; (3) adopt spring leaf can effectively control the pressure between friction piece and rubbing surface, improve the efficiency of break-in, also can meet the pressure demand of the friction piece of different size.

Embodiment
As shown in Fig. 1-7, electric mill brush device of the present utility model, comprise columniform friction piece 1, ring flange 2, drive motors 3, brush holder dish 4, spring leaf 5 and brush carrier 6, the excircle of friction piece 1 is coarse rubbing surface, and be removably mounted on the driving shaft of drive motors 3, one side of ring flange 2 is arranged on drive motors 3, opposite side and brush holder dish 4 are detachably installed, spring leaf 5 and brush carrier 6 mounted in pairs are on brush holder dish 4, spring leaf 5 is positioned at the brush socket top of brush carrier 6, the just rubbing surface to friction piece 1 of the brush socket of brush carrier 6.
As shown in Fig. 3,4 and 7, in the installing hole of friction piece 1, be provided with friction piece keyway 7, the driving shaft of drive motors 3 is provided with drive shaft keyways 8, and friction piece keyway 7 is detachably installed by fitting key 11 with drive shaft keyways 8.
As shown in Figure 2, in the time of actual installation spring leaf 5 and brush carrier 6, spring leaf 5 can be set and brush carrier 6 is four pairs, and evenly be arranged on the circumference of brush holder dish 4.
As illustrated in Figures 5 and 6, ring flange 2 is provided with the motor installing hole 9 of installing mutually with drive motors 3, is also provided with the brush holder dish installing hole 10 of installing mutually with brush holder dish 4.
Electric mill brush device of the present utility model is in the time of work, first select suitable friction piece 1 according to the diameter of axle size of commutator, friction piece 1 is arranged on the driving shaft of drive motors 3, and then the brush that needs break-in is put in the brush socket of brush carrier 6, and by spring leaf 5, brush is pressed on friction piece 1, then starting drive motors 3 drives friction piece 1 to rotate, now, brush rubs with friction piece 1, because the excircle of friction piece 1 is coarse rubbing surface, so only need time a few minutes just surface of the electric brush can be ground to a cambered surface matching with friction piece 1, also just match with the surface of commutator, greatly save the time, enhance productivity, the consumption of also having saved electric energy simultaneously.
