a grinding device

Abstract

A polishing device comprises a polishing machine shell, an annular assembling groove stretching upwards and downwards is formed in the polishing machine shell, a middle rotating groove stretching upwards and downwards and communicating with the annular assembling groove is formed in the annular assembling groove, guide connecting rods are fixedly installed between the upper wall and the lower wall of the annular assembling groove, and a slipping pipe sleeve is fixedly installed on the guide connecting rods. An annular cavity is formed in the inner end of the slipping pipe sleeve, the open end face of the annular cavity faces to the middle rotating groove, a rotating frame can be installed in the middle rotating groove in a rotatable and up-and-down slipping mode, the rotating frame is rotatably connected with the inner end of the slipping pipe sleeve through a rotating bearing, and a tooth edge is installed in the annular cavity and fixedly connected with the rotating frame. An assembling groove is further formed in the slipping pipe sleeve, the open end face of the assembling groove faces to the annular cavity, a motor is fixedly installed in the top end of the assembling groove, a rotating shaft is fixedly installed on the motor, the lower end of the rotating shaft stretches downwards into the assembling groove and is fixedly provided with a tooth-shaped wheel, and the tooth-shaped wheel is meshed with the tooth edge.

Description

technical field [0001] The invention relates to the field of grinding facilities, in particular to a grinding device. Background technique [0002] In the process of house decoration, it is necessary to paint the walls. The traditional painting process tends to make the walls uneven, so the walls need to be polished.
