Abstract
The utility model relates to an electric tool, in particular to an electric angle grinder. The electric angle grinder comprises an enclosure with a horizontal cavity, wherein a motor is arranged in the enclosure; a rotor of the motor is arranged along the horizontal cavity; a pair of bevel gears which is perpendicularly meshed with each other is arranged on the enclosure; one of the bevel gears is arranged at one end of the rotor of the motor, and the other bevel gear is arranged at one end of an output shaft; a grinding wheel sheet is arranged at the other end of the output shaft; and the other end of the rotor is connected with a carbon brush. The bevel gears which are perpendicularly meshed with each other drive the grinding wheel sheet to rotate, so that the transmission noise is relatively small; furthermore, circuits are connected in a manner of the carbon brush, so that the size of the angle grinder can be properly reduced; and moreover, the angle grinder is provided with a self-locking device, so that the safety of the angle grinder can be improved.
Description
Technical field
The utility model relates to electric tool, is electronic angle grinding machine specifically.
Background technology
The angle grinding machine is electric angle grinder again, is mainly used in the surperficial burr of buffing work-piece, overlap etc.Existing angle grinding machine one is removed and is comprised casing, is provided with motor and gear-box in the casing, is provided with travelling gear in the gear-box.During use, opening power, the rotor rotation of motor is rotated through the gear driven grinding wheel and is rotated.Like this, the grinding wheel of rotation contacts the effect that reaches polishing with surface of the work.But present angle grinding machine volume is bigger, and in use, not only noise is bigger, and security performance is not enough.
The utility model content
The utility model has solved above-mentioned technical problem, provides that a kind of volume is less, noise is less and has the electronic angle grinding machine of auto-lock function.
The technical scheme that the utility model solves the problems of the technologies described above employing is: electronic angle grinding machine, comprise the casing that forms horizontal cavity, and be provided with motor in the said casing; The rotor of this motor is along the horizontal cavity setting; Be provided with the helical gear of a pair of mutual Vertical Meshing in the said casing, wherein a helical gear is installed in rotor one end of said motor, and another helical gear is installed on an output shaft one end; The said output shaft other end is provided with grinding wheel, and the said rotor other end is connected with carbon brush.
The utility model also has following additional technical feature:
Top board and lower platen are installed on the said output shaft, said grinding wheel is installed between upper and lower pressing plate.
Said casing is provided with and automatically locks said another helical gear self-locking device.
Can know that from above technical scheme the utility model drives the grinding wheel rotation through the helical gear of Vertical Meshing, its rotational noise is less; And the mode through carbon brush realizes that circuit connects, and can suitably reduce the volume of angle grinding machine; The utility model also is provided with self-locking device in addition, can improve the security of angle grinding machine.
Description of drawings
Fig. 1 is the plan structure sketch map of the utility model;
Fig. 2 is an A-A cross-sectional schematic among Fig. 1.
The specific embodiment
Specify the utility model below in conjunction with accompanying drawing 1 to Fig. 2:
This electronic angle grinding machine comprises the casing 1 that forms horizontal cavity, is provided with motor 2 in the said casing, and the rotor 21 of this motor is provided with the helical gear of a pair of mutual Vertical Meshing along the horizontal cavity setting in the said casing 1, its stable drive, and noise is less; Wherein a helical gear 3 is installed in rotor 21 1 ends of said motor; Another helical gear 4 is installed on an output shaft 5 one ends; Said output shaft 5 other ends are provided with grinding wheel 6; Said rotor 21 other ends are connected with carbon brush 7, and the utility model forms circuit through carbon brush, inductance etc. and connects, and can suitably reduce the volume of angle grinding machine.
In this embodiment, top board 8 and lower platen 9 are installed on the said output shaft 5, said grinding wheel 6 is installed between upper and lower pressing plate, guarantee grinding wheel stable drive when work, improve security; Said casing 1 is provided with and automatically locks said another helical gear self-locking device 10; Self-locking device can be realized through on said another helical gear, opening the hole and self-lock pin being set on casing; Also can realize, can further improve the security of this angle grinding machine like this through other modes.
Above-mentioned embodiment only supplies to explain the usefulness of the utility model; And be not to be the restriction to the utility model; The those of ordinary skill in relevant technologies field; Under the situation that does not break away from the utility model spirit and scope, can also make various variations or modification, so all technical schemes that are equal to also should belong to the category of the utility model.
