Abstract
The utility model relates to a novel angle grinder, including casing, rear cover, stator and rotor, the casing is built -in to have a stator, and the rotor is installed at the stator center, and casing end is a rear cover that is covered with the ventilation hole, be equipped with the switch on the casing, the casing rear end is located to the switch, and the interior terminal surface at the rear cover is equipped with an annular wind -guiding circle, and the stator is hugged closely to the interior terminal surface of this wind -guiding circle, the rear cover passes through the bolt fastening on the casing. The utility model has the advantages of: the utility model discloses an angle mill, switch are put in the casing back, and with the direct toggle switch of hand, the break -make is nimble, and is easy and simple to handle, and the interior terminal surface at the rear cover increases by an annular wind -guiding circle, makes more wind flow out between stator and rotor for and the heat between the rotor weakens, and then improves the life of motor and bearing, makes work efficiency also improve greatly.
Description
Technical field
This utility model relates to field of power tools, particularly to a kind of Novel angle grinder.
Background technology
Angle grinding machine is a kind of grinding tool for fiberglass cutting and polishing, for the conventional product in market.The angle grinding machine switch of prior art is placed on cabinet sides, drives switch by pull bar.After use time length, pull bar is easily deformed, and pulling force reduces, thus affecting switch on and off；And angle grinding machine is in running work, rotating speed is very fast, gathers heat very big, thermal diffusivity is not as, and heat radiation major part can only shed from the space between stator and casing, and the radiating effect between rotor and stator is just very poor, thus affect service life of stone material angle grinding machine, reduce work efficiency.
Therefore, the Novel angle grinder researching and developing a kind of service life that can extend angle grinding machine and raising work efficiency is necessary.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of service life that can extend angle grinding machine and improves the Novel angle grinder of work efficiency.
For solving above-mentioned technical problem, the technical solution of the utility model is: a kind of Novel angle grinder, including casing, back cover, stator and rotor, casing is built-in with stator, stator center is provided with rotor, casing end is a back cover being covered with air vent, and its innovative point is in that: described casing is provided with switch, and casing rear end is located at by described switch；And it being provided with an annular air-ducting ring at the inner face of back cover, the inner face of this air-ducting ring is close to stator.
Further, described back cover is bolted in casing.
The utility model has the advantage of: angle of the present utility model grinding machine, switch is placed on after casing, and with the direct toggle switch of hands, break-make is flexible, easy and simple to handle；And increase by an annular air-ducting ring at the inner face of back cover, make more wind flow out between stator and rotor so that and the heat between rotor weakens, and then improve the service life of motor and bearing so that and work efficiency also substantially increases.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, this utility model is described in further detail.
Fig. 1 is the structural representation of Novel angle grinder of the present utility model.
Detailed description of the invention
The following examples can make professional and technical personnel more fully understand this utility model, but is not therefore limited among described scope of embodiments by this utility model.
Embodiment
The present embodiment Novel angle grinder, including casing 1, back cover 4, stator 2 and rotor 3, casing 1 is built-in with stator 2, and stator 2 center is provided with rotor 3, and casing 1 end has been bolted back cover 4, and casing 1 is provided with switch 6, and casing 1 rear end is located at by this switch 6；And it being provided with an annular air-ducting ring 5 at the inner face of back cover 4, the inner face of this air-ducting ring 5 is close to stator 2.
The Novel angle grinder of the present embodiment, switch is placed on after casing, and with the direct toggle switch of hands, break-make is flexible, easy and simple to handle；And increase by an annular air-ducting ring at the inner face of back cover, make more wind flow out between stator and rotor so that and the heat between rotor weakens, and then improve the service life of motor and bearing so that and work efficiency also substantially increases.
Of the present utility model ultimate principle and principal character and of the present utility model advantage have more than been shown and described.Skilled person will appreciate that of the industry; this utility model is not restricted to the described embodiments; described in above-described embodiment and description is that principle of the present utility model is described; under the premise without departing from this utility model spirit and scope; this utility model also has various changes and modifications, and these changes and improvements both fall within the scope of claimed this utility model.This utility model claims scope and is defined by appending claims and equivalent thereof.
