Angle grinder with excellent waterproof and dustproof performances

Abstract

The invention discloses an angle grinder with excellent waterproof and dustproof performances. The angle grinder comprises a main shaft casing, a motor casing and an annular grab handle, wherein a waterproof shielding can is arranged at the lower end of the main shaft casing; a main shaft vibration damping structure is arranged below the waterproof shielding can; a multi-gear speed-control switchis arranged on the outer surface of the motor casing; a press switch is arranged at the lower end of the annular grab handle; a dustproof air inlet is formed in one side of the press switch; a space gear assembly is arranged inside the main shaft casing; and a high-power motor is arranged inside the motor casing. The angle grinder with excellent waterproof and dustproof performances disclosed by the invention is provided with the waterproof shielding can, a dustproof fan, the main shaft vibration damping structure and the multi-gear speed-control switch, water and dust prevention can be realized, and the service life and safety can be ensured. Moreover, vibration of a grinding wheel can be reduced by the main shaft vibration damping structure, so that the noise is reduced, the rotating speed can be freely adjusted, and the angle grinder is applicable to different working conditions and brings excellent application prospects.

Description

Technical field [0001] The invention relates to the field of angle grinders, in particular to an angle grinder with good waterproof and dustproof performance. Background technique [0002] Angle grinder, also known as grinder or disc grinder, is a portable electric tool that uses glass fiber reinforced plastic to cut and polish. It is mainly used for cutting, grinding and brushing metals and stones. Electric angle grinders use high-speed rotating sheet grinding wheels, rubber grinding wheels, wire wheels, etc. to grind, cut, rust, and polish metal components. Water is not allowed during operation. Because of the high speed of the angle grinder, when using the saw blade, the cutting blade cannot be pressed hard, and hard materials with a thickness of more than 20 mm cannot be cut. Otherwise, once it is stuck, the saw blade and the cutting blade will be broken and splashed, or the machine will bounce off. Loss of control can cause damage to objects in the slightest, and injury to ...

AI Technical Summary

Problems solved by technology

Because of the high speed of the angle grinder, when using a saw blade, do not apply force when cutting the blade, and cannot cut hard materials with a thickness of more than 20 mm. Otherwise, once it is stuck, the saw blade and cutting blade will be broken and splashed, or the machine will bounce. Out of control, ranging from damage to objects, to serious injuries

[0003] Existing angle grinders have certain disadvantages in use. First, the waterproof and dustproof performance is poor. The internal motor is often damaged due to water and dust, which affects the service life. Secondly, the vibration noise is large during use, which affects the use. Finally, the angle grinder has a high speed, cannot be adjusted, and has a single function, which has a certain impact during use. Therefore, we propose an angle grinder with good waterproof and dustproof performance.
