Description
Technical field
The utility model relates to a kind of electric tool, particularly a kind of portable electric angle grinder that is used for metal removal and polishing.
Background technology
At present, electric angle grinder various in style mainly is used for metal removal, polishing.Electric angle grinder roughly comprises: handle, switch, casing, motor, middle cover, head capsule, protecgulum, pinion, output shaft, gear wheel, grinding wheel guard shield, grinding wheel, and switch is installed on the handle, and handle is fixed on the casing; Motor is installed on casing and the middle cover; Pinion is fixed on the motor output shaft, and head capsule is fixedly connected with casing and middle cover, and protecgulum is fixed on the head capsule; Output shaft is arranged on head capsule and the protecgulum rotationally; Gear wheel is fixed on the output shaft, and gear wheel and pinion realize transmission, deceleration and the switching-over of power through big pinion.But in use also there is following weak point: the one, there is not grinding wheel transposing self-locking mechanism on the head capsule, output shaft can be followed rotation during the grinding wheel transposing, needs with two spanners ability interchangeable grinding wheels.The 2nd, the speed ratio of big pinion is little, and output torque is little, inefficiency.The 3rd, the output shaft anti-dust performance is poor, and dust very easily gets in the head capsule, causes bearing and big or small gear lubrication weak effect.For this reason, many manufacturers and knowledgeable people develop and manufacture experimently to the problems referred to above, but do not find comparatively reasonably solution so far as yet.
Summary of the invention
In order to overcome the problems referred to above that existing electric angle grinder exists, the purpose of the utility model provide a kind of simple and reasonable, output torque big, the electric angle grinder of grinding wheel transposing convenience, good dustproof effect, long service life.
The utility model solves the problems of the technologies described above the technical scheme that is adopted; It comprises handle, switch, casing, motor, middle cover, head capsule, protecgulum, pinion, output shaft, gear wheel, grinding wheel guard shield, grinding wheel, and motor is installed in the casing, and pinion is fixed on the motor output shaft; Described output shaft is arranged on head capsule and the protecgulum rotationally; Gear wheel is fixed on the output shaft, gear wheel and pinion, and grinding wheel is fixed on the output shaft through last lower platen; Described head capsule is provided with self-locking mechanism; This mechanism comprises locking press button, self-locking spring, self-lock pin; What self-lock pin was movable is arranged on the head capsule installing hole, and the self-lock pin inboard is provided with spacing back-up ring, and the outside and locking press button are fixed; Self-locking spring is set on the self-lock pin between head capsule and the locking press button, and gear wheel is provided with the self-locking hole that matches with the self-lock pin head.
Described protecgulum is provided with dust cap.
The speed ratio of said pinion and gear wheel is 3.416.
After adopting said structure, following advantage and effect are relatively arranged with prior art:
The one, it is more laborsaving, convenient that self-locking mechanism is not only manipulated, and can shorten the time of transposing grinding wheel, increases work efficiency.
The 2nd, the speed ratio of big cone pinion is big, and the output shaft output torque is big, and output torque can reach 1.5N.m, and power is big, can reach 1400W, high efficiency.
The 3rd, on protecgulum, be provided with dust cap, good dustproof effect has solved dust and has got into the problem that influences big pinion and bearing lubrication in the head capsule.
