A lithium electric angle grinder

Abstract

The invention discloses a lithium-battery angle grinder. The lithium-battery angle grinder comprises a handle and a grinding wheel, a motor is arranged in the handle, the motor drives an output shaftto rotate through a transmission mechanism, one end of the output shaft extends out of the handle, and the grinding wheel is fixed to the end, extending out of the handle, of the output shaft; the lithium-battery angle grinder further comprises a rear check ring and a front check ring, the top of the rear check ring is fixed to handle, the bottom of the rear check ring covers the outer circle of the side, facing an operator, of the grinding wheel, the front check ring is made of iron materials, the top of the front check ring is slidably connected to the output shaft, the bottom of the front check ring covers the outer circle of the side, back on to the operator, of the grinding wheel, and an electromagnet is further arranged on the output shaft.

Description

technical field [0001] The invention relates to an angle grinder, in particular to a lithium electric angle grinder. Background technique [0002] The angle grinder is a kind of equipment used to grind the surface of parts. When the angle grinder grinds the product, it will produce a lot of powder, which will cause some harm to the human body. Especially when the angle grinder is processing iron products, it will generate high-temperature iron filings powder and form sparks. These sparks are dangerous to a certain extent. If they touch flammable items, they may cause a fire. [0003] To solve the dust generated when the angle grinder works, CN206869619U discloses a kind of angle grinder, comprising an angle grinder body, an isolation cover and a vacuum cleaner, the front end of the angle grinder body is provided with a grinding wheel; the isolation cover is transparent Hemispherical and covered on the grinding wheel, the front and rear side walls of the isolation cover are ...

AI Technical Summary

Problems solved by technology

But there is a big problem with this structure, that is, the cover affects the processing of the grinding wheel, so that the grinding wheel cannot touch the processing parts

So in fact this kind of product cannot be manufactured

[0005] At the same time, the grinding wheel on the angle grinder is relatively brittle, and it is easy to break after being hit, and the original exposed grinding wheel is also easily damaged.
