Double-track eccentric structure polishing machine

Abstract

The invention relates to an electric tool and specifically relates to a double-track eccentric structure polishing machine. The double-track eccentric structure polishing machine comprises a machine body, an eccentric block, a rolling bearing, an eccentric shaft and a polishing plate, wherein a driving motor is arranged in the machine body; the driving motor is connected with an output shaft; an upper hole matched with the output shaft is formed in the upper part of the eccentric block; a lower hole matched with the eccentric shaft is formed in the lower part of the eccentric block; the upper hole and the lower hole are non-concentric; the eccentric shaft comprises a shaft body and a lower end socket; the diameter of the lower end socket is more than the diameter of the shaft body; an inner ring of the rolling bearing is mounted on the shaft body; an external retaining ring is mounted at the upper end of the shaft body; an outer ring of the rolling bearing is fixed on the eccentric block through a bolt; the eccentric shaft is fixedly connected with the polishing plate. The eccentric block structure design is adopted by the invention; the polishing plate is rotated around the output shaft and the eccentric shaft, so that a double-track motion curve is formed; during a use process, the double-track eccentric structure polishing machine is labor-saving and high-efficient; the polishing quality is greatly increased; the specialty of the user is greatly reduced.

Description

technical field [0001] The invention relates to an electric tool, in particular to a double track eccentric structure polishing machine. Background technique [0002] Both polishing machines and angle grinders are electric tools. The polishing machine is composed of basic components such as a body, a polishing disc, a polishing fabric, and a polishing cover. The motor is fixed on the machine body, and the taper sleeve used for fixing the polishing disc is connected with the motor shaft through screws. The polishing fabric is fastened on the polishing disc through a ferrule. After the motor is powered on through the switch on the base, the sample can be polished by hand to apply pressure on the rotating polishing disc. The 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 grinders are suitable for cutting, grinding and brushing metal and stone. [0003] Most of...

AI Technical Summary

Problems solved by technology

[0003] Most of the polishing machines on the market are coaxial and concentric polishing machines, which are laborious to use and require very professional personnel to operate.

In addition, due to the coaxial and concentric design, the polishing load acts directly on the output end, which has a great impact on the service life of the equipment (motor)

[0004] In addition, the power tools on the market now either have the function of angle grinding or the function of polishing
