Description
Technical field
The utility model is related to motor production field, the brush welding accurate location device of particularly a kind of brush motor.
Background technology
Brush position is to ensure that the essential condition of brushed DC motor brush normal commutation.A kind of common brush assembly is by leading
Electric piece and brush are constituted, and brush is welded on conducting strip both sides.Between two brushes, there is certain status requirement, if site error
Larger may result in brush and commutator segment contact position in use to produce larger spark, thus accelerating brush wear, shorten
Motor service life.At present frequently with mating holes is bored on conducting strip, coordinated with brush cylinder boss by this hole, determine brush
Welding position.But find in use, position by this method, two brush positions and ideal situation after the completion of welding
There is larger error.Analysis finds, this brush positioning mode has two problems: one when being boring on conducting strip, boring
Positions and dimensions precision is difficult to control to, and brush boss precision is difficult to ensure；Two be after boring on conducting strip will through bending and
, there is bending error and metaboly in heat treatment step.The application avoids the error of above-mentioned positioning mode, when realizing brush welding
It is accurately positioned.
Content of the invention
Technical problem to be solved in the utility model is to provide for a kind of position accuracy demand improving welding brush
The brush welding accurate location device of brush motor.
In order to solve above technical problem, the brush welding that the utility model provides a kind of brush motor is accurately positioned
Device, including fixed seat, brush fixed mount, conducting strip fixed mount, cushion block, adjustment sheet, fixed column, screw and fixed block.Described
Fixed seat is provided with endoporus and groove, and the endoporus of fixed seat is connected with the axle of brush fixed mount, and on brush fixed mount, circumferencial direction is provided with
Four pairs of grooves, groove size is equivalently-sized with brush, and between a pair of groove, position is identical with brush angle design load when using；Fixing
In the groove of seat, conducting strip fixed mount is installed, after conducting strip fixed mount adjusting position, fixing locking, opens above conducting strip fixed mount
There is sulculus, in sulculus, conducting strip is installed, two brushes are put in a pair of groove of brush fixed mount, two brushes and conducting strip solder side
It is fully contacted.
Described conducting strip fixed mount has the boss matching with fixing seat slot, conducting strip fixed mount is machined with width and leads
Electric piece identical groove and conducting strip location hole.
Described conducting strip fixed mount is locked to conducting strip fixed mount by screw and fixed block.
Described fixed block is embedded in the groove in fixed seat.
Described brush fixed mount bottom is provided with the cushion block supporting brush.
The side of described conducting strip fixed mount is provided with adjustment sheet, is fixed by selecting the thickness of adjustment sheet to adjust conducting strip
The position of frame.
Described adjustment sheet has the thin slice of high flatness and dimensional accuracy for both ends of the surface.
It is provided with the sulculus of width dimensions very little, little groove width is slightly larger than conducting strip thickness, little above described conducting strip fixed mount
The side of groove is drilled with an aperture, for fixed-conductive film.
The utility model when using, brush is arranged in a pair of groove of brush fixed mount circumferencial direction, and conducting strip is installed
On conducting strip fixed mount, and by fixed column, conducting strip is fixed.Weld front two brush positions, and brush and conducting strip
Position is identical with brush assembly of electric use state, meets the required precision of brush assembly of electric when using.
Superior effect of the present utility model is:
1st, brush welding positioning precision can be improved: on brush fixed mount circumference, a pair of groove location has very high precision and want
Ask, rack position can be fixed to conducting strip by replacing adjustment sheet simultaneously and be adjusted, to ensure two brush positions during welding, and electricity
When brush is used with brush assembly of electric with conducting strip position, state is identical；
2nd, there is good versatility: only need to change brush fixed mount, readjust conducting strip and fix rack position, just can expire
The welding requirements of sufficient different size brush assembly of electric；
3rd, brush fixed mount circumferencial direction is machined with four pairs of shape identical grooves, after one pair of which groove damages, can use
Another to groove positioning, improve the service life of brush fixed mount.
Brief description
The Figure of description constituting the part of the application is used for providing further understanding to of the present utility model, this practicality
New schematic description and description is used for explaining the utility model, does not constitute to improper restriction of the present utility model.

Specific embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described in detail, but the utility model can be by right
The multitude of different ways limiting and covering is required to implement.
Describe embodiment of the present utility model below in conjunction with the accompanying drawings in detail.
Fig. 1 is the structural representation of the utility model embodiment.As shown in figure 1, the utility model provides one kind brush
The brush welding accurate location device of motor, including fixed seat 1, brush fixed mount 2, conducting strip fixed mount 5, cushion block 3, adjustment sheet
4th, fixed column 6, screw 7 and fixed block 8.Endoporus and the groove of high precision had on described fixed seat 1, the axle of brush fixed mount 2 with solid
Reservation 1 endoporus high accuracy is connected, and on brush fixed mount 2, circumferencial direction has four to equivalently-sized groove.Groove size and electricity
