Description
Technical field
The invention belongs to the assembling device of DC motor brush rack, be mainly used in brush carrier when DC motor brush rack assembles
Installation.
Background technology
Commutation spark is the mark of reversing performance of DC motor, produces one of them major reason of commutation spark and is
Owing to each group of brush is at commutator face skewness, cause some elements of winding that same polarity brush is short-circuit
The most not at the correspondence position in magnetic field, it is shorted element the most inconsistent for commutating period, commutating potential and reactance ripple
Shape is misaligned.This, in addition to electric potential of branch does not wait and produces circulation, also makes the induced potential summation in commutation element
It is not zero.Produce the additional current of commutation, so that the brush of some group produces commutation spark, harmful commutation
Spark not only can destroy the sliding contact between brush and diverter, and makes brush aggravate with commutator wear,
It is also possible to cause ring fire accident, badly damaged motor.
Assemble Zhong Ge electrical machinery plant at brush holder and commonly use the brush holder assembling device of a kind of band location tire, this kind of device
Main deficiency is that versatility is strong, and often overlapping this device all can only the high brush holder in corresponding a kind of center.
Summary of the invention
The present invention is in order to overcome the defect of above-mentioned existence, it is provided that a kind of DC motor brush rack assembling device, not only
The each group brush making direct current generator is evenly distributed along commutator face, controls the brush carrier distance to diverter, more
It is important that have only to this device a set of, all centers height direct current generator can be met.
Technical scheme is as follows:
A kind of DC motor brush rack assembling device, including underframe, underframe is provided with workbench, on workbench
It is provided with four groups of screw rodb bases, wherein between three groups of screw rodb bases, screw mandrel is installed, be provided with between another group screw rodb base
Drive link, three screw mandrels are uniform on workbench circumference, and each screw mandrel and drive link all have one end and be arranged on
The gear engagement of table core, three claws are respectively sleeved on screw mandrel and are in the track of table surface
In, the other end of drive link is provided with handwheel；The center of workbench and gear is run through a main shaft, cantilever
Being connected by sleeve and main shaft are vertical, scale is vertically connected on the end of cantilever；Index dial is fixed on screw rodb base
Above and being connected with main shaft by fixing seat, pointer is fixing with main shaft to be connected.
The method have the benefit that:
DC motor brush rack assembling device of the present invention has spy reasonable in design, that versatility is extremely strong, simple to operate
Point.The distance away from, brush carrier with commutator face of brushing each row brush held before motor assembles is adjusted, and makes dress
Join, easy construction, accuracy is high.This device not only increases production efficiency and conforming product rate, Er Qieyi
Covering device can meet all centers height DC motor brush rack and assemble.
Advantages of the present invention will be given in the description of detailed description of the invention part below, and part is by from following
Description becomes obvious, or recognized by the practice of the present invention.
Accompanying drawing explanation
Fig. 1 is the structural representation of the present invention.
Detailed description of the invention
Below in conjunction with the accompanying drawings the detailed description of the invention of the present invention is described further.
As it is shown in figure 1, the present invention is mainly made up of underframe 1, chuck, indexing means, adjusting rotating device.
Chuck, indexing means, adjusting rotating device are the most directly or indirectly arranged on underframe 1.
Chuck includes workbench 5, screw mandrel 6, screw rodb base 7, claw 8, track 9, gear 10, drive link
11 and handwheel 12, it is mainly used in fixing brush rack base.Concrete structure is, workbench 5 is arranged on underframe 1
On, which is provided with four groups of screw rodb bases 7, wherein between three groups of screw rodb bases 7, screw mandrel 6 is installed, another organizes silk
Being provided with drive link 11 between pole socket 7, three screw mandrels 6 are uniform, respectively every 120 degree on workbench 5 circumference
Individual screw mandrel 6 and drive link 11 all have one end and engage with the gear 10 at 5 centers that are arranged on workbench, three cards
Pawl 8 is respectively sleeved on screw mandrel 6 and is in the track 9 on workbench 5 surface, and handwheel 12 is arranged on biography
The other end of lever 11.
Indexing means includes pointer 13 and index dial 14, and main cooperation with adjusting rotating device is used for regulating often
Row brush holds spacing decile.Adjusting rotating device includes fixing seat 15, main shaft 16, sleeve 17, cantilever 18
And scale 19 becomes, be mainly used in adjusting the distance between brush carrier and diverter, each row brush hold between
Arrangement axis is held parallel with electrical axis away from, every row brush.Concrete structure is, main shaft 16 is applied in workbench 5
And the center of gear 10, cantilever 18 is connected by sleeve 17 is vertical with main shaft 16, and scale 19 vertically connects
It is connected on the end of cantilever 18；Index dial 14 is fixed on screw rodb base 7 and by fixing seat 15 and main shaft 16
Connecting, pointer 13 is fixing with main shaft 16 to be connected.
The operational approach brief introduction of the present invention:
Brush rack base is positioned on three claws 8, rotarily drives drive link 11 by handwheel 12, drive tooth
Wheel 10 rotation, three screw mandrels 6 passively rotate under the drive of gear 10, and the rotary motion of screw mandrel 6 changes
For the horizontal movement of claw 8, three claws 8 uniform on chuck perimeter are made to move inward along track 9,
Synchronous clamping brush rack base.Correction scale 19 and the perpendicularity of workbench 5, place brush holder support on brush rack base,
And substantially fix the position of brush holder support with bolt, then by the slow rotation of main shaft 16, drive scale 19 with
