Abstract

The invention relates to a grinding machine, particularly relates to an automatic grinding machine for an arc-shaped corner of a chair backrest, and aims to provide the automatic grinding machine forthe arc-shaped corner of the chair backrest, which can be used for fixing chairs with different heights, uniformly grinding arc-shaped corners of the chair backrests with the different heights and collecting wood chips falling off after grinding. According to the technical scheme of the machine, the automatic grinding machine for the arc-shaped corner of the chair backrest comprises a second support, a supporting device, a first support and the like, wherein the supporting device is fixedly connected to the top of the second support, the first support is installed at the top end of the supporting device, and the first support is in a 7-shape. According to the machine, a second fixing block can be driven to rotate anticlockwise through unidirectional rotation of a chain, the second fixing block rotates anticlockwise to continuously drive a sliding rail to move left and right and drive a rechargeable polishing machine to move up and down to grind the arc-shaped corner on one side of thechair backrest, and the grinding position can be adjusted in the front-back direction and the left-right direction.

Description

technical field [0001] The invention relates to a grinding machine, in particular to an automatic grinding machine for arc angles of the back of a chair. Background technique [0002] A chair is a kind of seat with a backrest and some with armrests. The chair is made through multiple processes such as cutting, splicing, polishing and coloring. When making a chair in a furniture factory, the workers generally need to correct the arc of the backrest of the chair. Grinding the corners.
