Abstract
The invention discloses a reversing device for the forward and backward rotation of an electric brush holder of an electric tool. The reversing device comprises a machine body, a driving motor, a rotary electric brush holder assembly and a forward and backward rotation switching assembly. The driving motor, the rotary electric brush holder assembly and the forward and backward rotation switching assembly are arranged in the machine body. A reverser of the driving motor is in contact with an electric brush which is fixedly arranged on the machine body through the rotary electric brush holder assembly. The forward and backward rotation switching assembly is also fixedly arranged on the machine body. A lifting lever of the forward and backward rotation switching assembly is inserted into the rotary electric brush holder assembly, and is synchronously linked with the rotary electric brush holder assembly. The reversing device for the forward and backward rotation of the electric brush holder is simple and rational in structure, light in overall weight and low in cost, and can be used safely and reliably; and the forward rotation and the backward rotation are switched flexibly and conveniently.
Description
Technical field
The present invention 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 invention is to provide 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 solution adopted for the present invention to solve the technical problems 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.
Beneficial effect of the present invention is: 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 structure of the present invention.
Fig. 2 is the structural representation of the rotatable brush holder assemblies of the present invention.
Fig. 3 is the structural representation of forward-reverse switch assembly of the present invention.
The specific embodiment
Below in conjunction with accompanying drawing the present invention 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 present invention 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.
