Angle grinding motor with long service life

Abstract

The invention discloses an angle grinding motor with long service life and belongs to the technical field of angle grinding motors. A double-head motor is started to drive a first output rotating shaft and a second output rotating shaft to rotate, and a cooling fan and a limiting sliding rod are driven to rotate through rotation of the first output rotating shaft and the second output rotating shaft. A limiting sliding cylinder is driven to rotate through the limiting sliding rod, and a first fixing disc and a second fixing disc are driven to rotate through the limiting sliding cylinder. The second fixing disc drives a penetrating rod to rotate, and the penetrating rod drives a polishing piece to rotate, so that polishing is achieved, the polishing piece is in contact with the curved surface during polishing, an adjusting component is compressed under the reaction force, so that self-adaption to different curved surfaces through adjustment is achieved; and the limiting sliding rod anda buffer spring are matched with each other under the reaction force of the polishing piece and the contact face during polishing, so that the buffering effect is achieved, damage to the sliding pieceis avoided, and heat dissipation is achieved through the cooling fan.

Description

technical field [0001] The invention relates to an angle grinder motor, in particular to an angle grinder motor with high service life, and belongs to the technical field of angle grinder motors. Background technique [0002] Angle grinder, also known as grinder or disc grinder, is a kind of abrasive tool used for cutting and grinding FRP. Angle grinder is a portable electric tool that uses fiberglass for cutting and grinding. It is mainly used for cutting, grinding and brushing metal and stone. [0003] Common models of angle grinders are divided into 100 mm (4 inches), 125 mm (5 inches), 150 mm (6 inches), 180 mm (7 inches) and 230 mm (9 inches) according to the accessories used. The small size angle grinder used was 115 mm. [0004] Electric angle grinder is to use high-speed rotating sheet grinding wheel, rubber grinding wheel, wire wheel, etc. to grind, cut, derust, and polish metal components. Angle grinder is suitable for cutting, grinding, and brushing metal and st...

AI Technical Summary

Problems solved by technology

[0005] Angle grinder motors in the prior art are inconvenient to adjust the angle during use, especially for curved surface structures that are not convenient enough for polishing and grinding. Secondly, they do not have a certain buffering effect when grinding or polishing, resulting in It is easy to cause damage to the blade when using it. In addition, there is no good heat dissipation component for the rotation of the motor to dissipate heat in a timely manner. Therefore, a high-life angle grinder motor is designed to optimize the above problems.
