Abstract
The utility model discloses a carbon brush radian grinding device, comprising an electrical machine, a module rack arranged on the front end of the electrical machine and a grinding wheel component arranged on the rotor axis of the electrical machine, wherein the grinding wheel component is arranged at the center of the module center, and a carbon brush positioning hole vertical to the surface of the grinding wheel is arranged on the module rack. The grinding wheel component comprises a rolling wheel arranged on the rotor axis of the electrical machine, the surface of the rolling wheel is provided with sand paper, and the rolling wheel is a model wheel with the same size as the commutator. The carbon brush after being grinded by the utility model has a more consistent radian with the commutator and smoother end face, and can ensure that the carbon brush and the commutator have larger contact surface and lower the noise when working.
Description
Technical field
The utility model relates to motor, is specifically related to a kind of carbon brush radian lapping device.
Background technology
In the motor operation course, its carbon brush and commutator interact, and will guarantee bigger contact-making surface between carbon brush front end end face and commutator, just more stable service behaviour can be arranged.But carbon brush is when machine-shaping, and its front end end face is more coarse, and radian is also accurate inadequately, if directly be used with commutator, not only contact-making surface is less, influences the service behaviour of commutator, and more coarse owing to end face, and noise is also bigger.
The utility model content
It is a kind of simple in structure that the purpose of this utility model is to provide, can grind the carbon brush radian lapping device of brush front end radian easily and accurately, carbon brush after the attrition process has radian more consistent with commutator and more smooth end face, can guarantee the noise when carbon brush and commutator have bigger contact-making surface and reduce work.
To achieve these goals, the technical solution adopted in the utility model is: a kind of carbon brush radian lapping device, it is characterized in that: comprise motor, be located at the mould bases of motor front end and be installed in abrasive wheel assembly in the rotating shaft of motor, described abrasive wheel assembly is located at the mould bases center, and mould bases is provided with and emery wheel surface carbon brush locating hole in vertical state.
Preferably, described abrasive wheel assembly comprises the runner in the rotating shaft that is installed in motor, and wheel surface is equipped with sand paper, and this runner is the model wheel onesize with commutator.
Preferably, described mould bases is the center for the rotating shaft with motor, evenly with encircling several arc wallboards of arranging, be provided with certain spacing between each arc wallboard, described carbon brush locating hole is located on the arc wallboard, certain spacing wherein is set is the discharge of dirt bits in order to be beneficial to carbon brush and to grind between each arc wallboard.
The utility model is owing to adopt technique scheme, during the processing radian, only carbon brush need be put into the carbon brush locating hole, pushing it against abrasive wheel assembly grinds and gets final product, because runner is the model wheel onesize with commutator, carbon brush after the attrition process has radian more consistent with commutator and more smooth end face, can guarantee the noise when carbon brush and commutator have bigger contact-making surface and reduce work.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further described.
Fig. 1 is the utility model example structure schematic diagram.
The specific embodiment
As shown in Figure 1, embodiment for a kind of carbon brush radian lapping device of the present utility model, comprise motor 1, be located at the mould bases of motor 1 front end and be installed in abrasive wheel assembly in the rotating shaft 11 of motor 1, described mould bases is that the rotating shaft 11 with motor 1 is the symmetrically arranged two arc wallboards 2 in center, 2 of two arc wallboards are provided with certain spacing, have carbon brush locating hole 21 on the arc wallboard 2, described abrasive wheel assembly is located at the mould bases center, abrasive wheel assembly comprises the runner 3 in the rotating shaft 11 that is installed in motor 1, sand paper 4 is equipped with on runner 3 surfaces, and this runner is the model wheel onesize with commutator.Certain spacing wherein be set be the discharge of dirt bits in order to be beneficial to carbon brush and to grind between two arc wallboards.
During carbon brush processing radian, only carbon brush need be put into the carbon brush locating hole, pushing it against abrasive wheel assembly grinds and gets final product, because runner is the model wheel onesize with commutator, carbon brush after the attrition process has radian more consistent with commutator and more smooth end face, can guarantee the noise when carbon brush and commutator have bigger contact-making surface and reduce work.
