Abstract
The invention provides a pneumatic angle grinder which comprises a grinding wheel. A grinding wheel cover is arranged on the outside of the grinding wheel and the grinding wheel is mounted on one side of a housing case via an output shaft, gaskets, a bearing holddown ring and a deep groove ball bearing are sleeved on the output shaft, a side handle is mounted on one side of the housing case, a cylinder and a rotor are mounted inside the housing case, a front end cover and a rear end cover are arranged at two ends of the cylinder, a locking nut is arranged on the outside of the cylinder and is screwed on a connector, an air inlet connecting rod is connected to the other end of the connector, an air inlet port is formed in the tail of the air inlet connecting rod, and a pressure plate is arranged on the outside of the air inlet connecting rod. The pneumatic angle grinder has the advantages that compressed air is used as a power source, the grinding wheel is pushed to rotate and work and can work in liquid environments, corresponding grinding wheels can be replaced according to different service places, the integral pneumatic angle grinder is compact in model design and smart in shape, ergonomic requirements can be met, and the labor intensity can be reduced.
Description
Technical field
The present invention relates to the reconditioning field of metal surface, specifically, is a kind of pneumatic angle grinding machine.
Background technology
Angle grinding machine is applicable to for cutting, grinding and brushing metal and stone material, electric angle grinder utilizes the disc wheel of High Rotation Speed and elastic grinding wheel, wire wheel etc. can carry out to hardware the processing such as grinding, cutting, rust cleaning, polishing, but can not there be water, wet goods liquid while using, and electric angle grinder is heavier, some special occasions uses inconvenience, and therefore, a kind of angle of needs grinding machine can be in the operation of multiple place, especially in water, wet goods liquid, operate, and lightly convenient.
Summary of the invention
It is more extensive for angle grinding machine is used, be applicable to more places, the invention provides a kind of pneumatic angle grinding machine, comprise grinding wheel, the outside of described grinding wheel is provided with wheel guard, described grinding wheel is installed to a side of casing by output shaft, on described output shaft, cover has pad, bearing hold-down ring and deep-groove bearing, one side of described casing is provided with side handle, the inside of described casing is provided with cylinder and rotor, the two ends of described cylinder are provided with drive end bearing bracket and rear end cap, the outside of described cylinder is provided with lock-nut, described lock-nut is screwed on joint, the other end of described joint connects air inlet extension bar, the afterbody of described air inlet extension bar is provided with intake interface, pressing plate is equipped with in the outside of described air inlet extension bar.
Wherein, described side handle is resin handle.
Between described bearing hold-down ring and described deep-groove bearing, it is oil sealing.
The invention has the beneficial effects as follows:
1) Compressed Gas is as energy source, and the rotor promoting in cylinder rotates, and with this, drives grinding wheel rotary work, can in liquid environment, work.
2) it is very simple and convenient that spindle lock mode is changed emery wheel, according to the needs of different fields of employment, can change the grinding wheel of different cultivars.
3) indoor design is compact, and moulding is light and handy, meets ergonomics, has reduced labour intensity, and it is lightly convenient to use.
Accompanying drawing explanation
