Abstract
An electric tool electric brush holder forward-backward rotation conversion device comprises an engine body, a drive motor, a rotary electric brush holder component, and a forward-backward rotation switch component. The drive motor, the rotary electric brush holder component and the forward-backward rotation switch component are installed inside the engine body. A commutator of the drive motor is contacted with an electric brush, the electric brush is fixedly installed on the engine body through the rotary electric brush holder component, the forward-backward rotation switch component is also fixedly installed on the engine body, and a deflector rod of the forward-backward rotation switch component is inserted into the rotary electric brush holder component and is in synchronous linkage with the rotary electric brush holder component. The electric tool electric brush holder forward-backward rotation conversion device is simple and reasonable in structure, flexible and convenient to convert, light in overall weight, low in cost, and safe and reliable to use.
Description
Technical field
The utility model relates to the brush carrier rotation rotating reversing arrangement of all electric tools.
Technical background
Development along with Power Tools Industries, of a great variety, and because the difference of cost factor, structural limitations, environment for use, operation or work standard, cause the electric tool that volume is little, weight is lighter in design process, will produce the phenomenon of compact conformation, thereby cause that the brush volume is little, service time is relatively short; If do when reversing not speed limiting function, at first drive motors parameter, coiling, the bad design of technique, secondly the wearing and tearing meeting of brush is more accelerated again.For this reason, many manufacturers and knowledgeable people constantly develop and study for the problems referred to above, improve one's methods but not yet have preferably so far.
Summary of the invention
For the rotating speed limit that overcomes existing electric tool, reverse not that speed limit causes the disadvantages such as brush is not wear-resisting; The purpose of this utility model provides a kind of simple in structure, easy to use and reliable, production and processing convenience, stable performance, lower-cost electric tool brush carrier rotation rotating reversing arrangement.
The technical scheme that its technical problem that solves the utility model adopts is:
A kind of electric tool brush carrier rotation rotating reversing arrangement, comprise body, drive motors, rotatable brush holder assemblies and forward-reverse switch assembly, drive motors, rotatable brush holder assemblies and forward-reverse switch assembly are installed in the described body, the commutator of described drive motors contacts with brush, and described brush is fixedly mounted on the body by rotatable brush holder assemblies; Described forward-reverse switch assembly also is fixedly mounted on the body; The driving lever of described forward-reverse switch assembly is inserted in the rotatable brush holder assemblies, the driving lever of described forward-reverse switch assembly and rotatable brush holder assemblies synchronous interaction.
Further, described operating mechanism comprises rotatable brush holder assemblies and forward-reverse switch assembly,
Described rotatable brush holder assemblies and forward-reverse switch assembly are fixedly mounted on the body successively, and the driving lever of forward-reverse switch assembly is inserted in the rotatable brush holder assemblies, thereby realize driving lever and the rotatable brush holder assemblies synchronous interaction of forward-reverse switch assembly.When rotatable brush holder assemblies rotated to an angle clockwise or counterclockwise to body, the driving lever that rotatable brush holder assemblies drives the forward-reverse switch assembly simultaneously clockwise or counterclockwise rotate to an angle.By the driving lever angle rotation of forward-reverse switch assembly, realize drive motors rotating conversion thereby reach the effect that changes the drive motors current direction.
The beneficial effects of the utility model are: simple and reasonable, conversion is flexible, complete machine is lightweight, cost is low, safe and reliable.
Description of drawings
Fig. 1 is the schematic diagram of the utility model structure.
Fig. 2 is the structural representation of the rotatable brush holder assemblies of the utility model.
Fig. 3 is the structural representation of the utility model forward-reverse switch assembly.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described further.
With reference to Fig. 1～Fig. 3, a kind of electric tool brush carrier rotation rotating reversing arrangement comprises body 1, drive motors, rotatable brush holder assemblies 2, forward-reverse switch assembly 3, forward-reverse switch main body 4 and forward-reverse switch driving lever 5.
Described operating mechanism comprises rotatable brush holder assemblies 2 and forward-reverse switch assembly 3; Described rotatable brush holder assemblies 2 and forward-reverse switch assembly 3 are fixedly mounted on the body 1 successively, the driving lever 5 of forward-reverse switch assembly 3 is inserted in the rotatable brush holder assemblies 2, thereby realizes driving lever and 2 synchronous interactions of rotatable brush holder assemblies of forward-reverse switch assembly 3.When rotatable brush holder assemblies 2 on body 1
(counterclockwise rotate to an angle) when the position rotates, the driving lever 5 that rotatable brush holder assemblies 2 drives forward-reverse switch assemblies 3 counterclockwise rotates to an angle simultaneously, thereby the realization drive motors rotates (forward) clockwise; When rotatable brush holder assemblies 2 on body 1
(rotate to an angle clockwise) when the position rotates, the driving lever 5 that rotatable brush holder assemblies 2 drives forward-reverse switch assemblies 3 counterclockwise rotates to an angle simultaneously, thereby the realization drive motors counterclockwise rotates (counter-rotating); Thereby change current of electric by the driving lever 5 of stirring forward-reverse switch assembly 3 and flow to realization rotating conversion.
The utility model realizes that above rotating commutation function and transformational structure are simple, safe and reliable, utilizes accessory less, thereby realizes alleviating electric tool weight and the design concept that do not affect the electric tool performance.
