Abstract
The utility model discloses a carbon brush frame for a motor. The carbon brush frame for the motor comprises a cuboid groove, wherein an upright post is fixed on the long side of the cuboid groove; a copper sheet is clamped in the middle of the upright post; a round hole is formed in the middle of the copper sheet; a spring capable of accommodating a carbon brush is clamped below the round hole in the vertical direction; the bottom of the spring is fixed on a pier; and the pier is fixed at the bottom of the cuboid groove. The carbon brush frame for the motor has the advantages that: the carbon brush is placed in the spring, the copper sheet for fixing the upper end of the spring is clamped in the middle of the upright post and the pier for fixing the lower end of the spring is positioned at the bottom of the cuboid groove, so the elastic force of the spring in the vertical direction is fixed and is not too large or too small, the carbon brush is protected and the motor can operate normally.
Description
Technical field
The utility model relates to carbon brush holder, relates in particular to the carbon brush for electric machine frame.
Background technology
Carbon brush holder is a kind of parts that supply carbon brush to place.Leave certain interval between carbon brush and the carbon brush holder to guarantee that carbon brush can slide in carbon brush holder under the effect of spring force.But the elastic force of spring is excessive or too small, all can influence the carbon brush operate as normal.Therefore, need provide a kind of new technical scheme to solve the problems referred to above.
The utility model content
The purpose of the utility model provides a kind of carbon brush that holds, the carbon brush for electric machine frame that can play a protective role again.
The technical scheme that the utility model adopts is:
The carbon brush for electric machine frame; It comprises the cuboid groove, and the long side of said cuboid groove is fixed with column, and said column middle part is connected with copper sheet; Have circular hole in the middle of the said copper sheet; Be connected with the spring that can hold carbon brush on the vertical direction of said circular hole below, said spring bottom is fixed on block of wood, and said block of wood is fixed in the cuboid trench bottom.
Said block of wood be shaped as circle.
The diameter of said block of wood is less than or equal to the length of cuboid groove width.
The beneficial effect of the utility model: carbon brush places in the spring; The copper sheet of fixing spring upper end is connected in the column middle part; Block of wood of fixing spring lower end is positioned at the cuboid trench bottom, so the elastic force of spring in the vertical direction is certain, and can be not excessive or too small; Play the effect of protection carbon brush, make motor run well.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Wherein: 1, cuboid groove, 2, column, 3, copper sheet, 4, circular hole, 5, spring, 6, block of wood.
Embodiment
As shown in Figure 1, the carbon brush for electric machine frame of the utility model, it comprises cuboid groove 1; The long side of cuboid groove 1 is fixed with column 2, and column 2 middle parts are connected with copper sheet 3, has circular hole 4 in the middle of the copper sheet 3; Be connected with the spring 5 that can hold carbon brush on the circular hole 4 below vertical directions; Spring 5 bottoms are fixed on circular block of wood 6, and block of wood 6 is fixed in cuboid groove 1 bottom, and the diameter of block of wood 6 is less than or equal to the wide length of cuboid groove 1.
Carbon brush places in the spring 5, and the copper sheet 3 of fixing spring 5 upper ends is connected in column 2 middle parts, and block of wood 6 of fixing spring 5 lower ends is positioned at cuboid groove 1 bottom; So the elastic force of spring 5 in the vertical directions is certain; Can be not excessive or too small, play the effect of protection carbon brush, make motor run well.
