Problems solved by technology

[0002] Teaching chairs are generally made of wood or composite materials. The four feet of the seat and the seat itself are usually fixed with bolts. Due to the manufacturing or installation errors of the feet, the bottom of the feet of the seat is easy to loosen after being fixed. In the case of different heights, the seat is prone to slight shaking during use, which affects the comfort of use. It is easy to shake during use, which reduces the comfort of subsequent use

Abstract

The invention discloses a grinding device for a chair for teaching. The grinding device comprises a machine frame, a positioning block, a supporting plate, a lifting assembly and a clamping assembly,wherein four positioning grooves distributed as vertexes of a rectangle are formed in the upper end of the positioning block, supporting columns are arranged at the lower end of the positioning blockand are fixed to the bottom of the machine frame, the supporting plate is located below the positioning block, two sliding rails and a fourth air cylinder are arranged at each of the two ends of the positioning block, sliding blocks which are connected to the sliding rails in a sliding mode are arranged on the sliding rails, grinding machines are arranged on the opposite sides of the sliding blocks at the two ends, grinding sheets of the grinding machines are consistent in height, piston rods of the fourth air cylinders are connected to the sliding blocks, the fourth air cylinders can push thesliding blocks at the two ends to slide on the sliding rails in the opposite direction or the backward direction, the positioning grooves are located on the moving tracks of the grinding machines correspondingly, the lifting assembly is located on the side surface of the machine frame and and can drive the supporting plate to vertically ascend and descend, and the clamping assembly is located atthe top of the machine frame. The grinding device has the advantages of being simple in using method, high in grinding efficiency, capable of grinding four supporting legs at a time, capable of ensuring that the bottoms of the supporting legs are consistent in height and capable of avoiding the phenomenon of chair shaking.

Description

technical field [0001] The invention relates to the field of seat processing equipment, in particular to a grinding device for teaching chairs. Background technique [0002] Teaching chairs are generally made of wood or composite materials. The four feet of the seat and the seat itself are usually fixed with bolts. Due to the manufacturing or installation errors of the feet, the bottom of the feet of the seat is easy to loosen after being fixed. In the case of different heights, the seat is prone to slight shaking during use, which affects the comfort of use. It is easy to shake during use, which reduces the comfort of subsequent use. Contents of the invention [0003] In view of this, the object of the present invention is to propose a polishing device for teaching chairs, so as to solve all or one of the above-mentioned defects in the background technology. [0004] Based on the above-mentioned purpose, the polishing device of the teaching chair provided by the present...
