Abstract
The invention provides a rotary carbon brush holder. The rotary carbon brush holder is characterized by comprising a base connected with a motor stator, a brush holder of which one end is connected with the base and one end is connected to a carbon brush, a copper piece fixed between the base and the brush holder, and two carbon brushes, wherein the two ends of the copper piece are two contacts, and the two carbon brushes are connected with the brush holder by use of copper bushes, respectively.
Description
Technical field
The present invention relates to technical field of motors, particularly relate to a kind of for motor can manual adjustment rotating carbon brush holder.
Background technology
Electric tool, such as hammer drill, electric drill, electric screwdriver etc., conventionally need to change direction of rotation and carry out operation, and traditional method is with an electric switch, by the direction of switching current, change the direction of rotation of instrument, and the brush device that has of motor can not be subjected to displacement.There is so individual shortcoming, when regulating direction of rotation, rely on the contact changing on switch to change direction of rotation, originally the electric current of up tool can be very large, and serious ablation contact also produces large spark, and then burn switch, and need in design to connect more circuit, and connector that increases filter, has shielding properties etc. guarantees that electromagnetism anti-interference (EMI) does not go wrong, and these measures cause the raising of production cost, otherwise will work the mischief to human body and social production activity.
Summary of the invention
The object of the invention is to overcome deficiency of the prior art, propose a kind of rotating carbon brush holder, by rotary plastic support, change sense of current, the direction of rotation of motor is changed.
The present invention proposes a kind of rotating carbon brush holder, it is characterized in that: comprising: a pedestal, is connected with motor stator; One brush holder, one end is connected with described pedestal, and one end connects carbon brush; One copper sheet, is fixed between described pedestal and described brush holder, the Wei Liangge contact, two ends of described copper sheet; And two carbon brush, by a copper sheathing, be connected with described brush holder respectively.
Wherein, described pedestal is fixedly connected with by a barb with brush holder.
Wherein, the two ends of described copper sheet are resilient contact.
Wherein, described copper sheet also comprises barbed pin.
Wherein, described copper sheet also comprises a salient point, corresponding with the groove on described brush holder.
Wherein, described copper sheathing comprises copper sheathing body and base plate, and described carbon brush is arranged in copper sheathing body.
Wherein, on described copper sheathing, be provided with wind spring.
The present invention proposes a kind ofly can change by rotary plastic support the method for motor direction of rotation, can maximum reduce costs and easily install.

Embodiment
Below in conjunction with accompanying drawing, describe specific embodiments of the invention in detail.
As illustrated in fig. 1 and 2, rotating carbon brush holder of the present invention comprises pedestal 2, copper sheet 3, brush holder 4 and carbon brush 5.Pedestal 2 is fixedly connected with motor stator 1 by two splicing ears 25.Between pedestal 2 and brush holder 4, be fastened and connected, the material of pedestal 2 and brush holder 4 is plastics, conventionally uses injection mo(u)lding processing.On brush holder 4, there is barb 13, as shown in Figure 3, by barb 13 and the chamber 14 on pedestal 2, agree with, can make pedestal 2 and brush holder 4 fixedly positioning, and can mutually rotate.While turning to, colliding by wall 15 on barb 13 meetings and chamber 14, so just can control the angle of rotation.
Copper sheet 3 is processed by pressing equipment, and be equipped with containing barbed pin 10 left and right, and after can making copper sheet 3 be mounted on pedestal 2, electric tool copper sheet 3 when vibrations can not be ejected.The two ends of copper sheet 3 are resilient contact 8, good to guarantee carbon brush 5 contacts.In the middle of copper sheet 3, a salient point 9 is set, brush holder 4 left and right are respectively provided with groove 11, as shown in Figure 4, when brush holder 4 rotation, drive groove 11,9 of salient points on copper sheet 3 can agree with locking with groove 11, guarantee can not cause because of vibrations rotational slide after brush holder 4 is rotated in place.
Carbon brush 5 contacts with brush holder 4 by a copper sheathing 7, as shown in Figure 5.Copper sheathing 7 is hardware, by diel, processes.On copper sheathing 7, have 4 riveting points 16, copper sheathing body 19 and base plate 20 carry out stamping riveting by riveting point 16 and are integrated.Carbon brush 5 can slide as requested by copper sheathing body 19.On copper sheathing 7, there are 4 screens 21, agree with in 4 holes 22 on brush holder 4, both can locate, also can design overhead kick increase and agree with intensity.In order to increase again the bonding strength between copper sheathing 7 and brush holder 4,26 upset riveted joint location, riveting point before and after being also provided with on copper sheathing 7.Wind spring 6 is fixed on the curved boom 17 of base plate 20, and wind spring 6 seesaws by passage 18, guarantees the isostasy that wind spring 6 provides when work, improves EMI performance.Wire on carbon brush 5 is connected on terminal 23.
During use, when brush holder 4 rotates in a direction, copper sheathing body 19 will rotate together along with brush holder 4, and contacts with the resilient contact 8 on copper sheet 3, and copper sheet 3 joins with the splicing ear 25 on stator 1.Carbon brush 5 is because the reason of wind spring 6 pressure can contact with rotor 24, and wire on carbon brush 5 is connected on terminal 23, carbon brush 5 and copper sheathing body 19 forms one and is connected, so just guaranteed electric tool switch on power after current direction from stator 1 to rotor 24, rotor will rotate.In like manner, when brush holder 4 is during to another direction rotation, electric current is just in time contrary through the direction of rotor 24, so rotor can change direction rotation.
Described in this specification is preferred embodiment of the present invention, and above embodiment is only in order to illustrate technical scheme of the present invention but not limitation of the present invention.All those skilled in the art, all should be within the scope of the present invention under this invention's idea by the available technical scheme of logical analysis, reasoning, or a limited experiment.
