Supporting shaft interior and exterior grinding and polishing device used for production and processing of swivel chair

Abstract

The invention discloses a supporting shaft interior and exterior grinding and polishing device used for the production and processing of a swivel chair, and relates to the technical field of production and processing of swivel chairs. The supporting shaft interior and exterior grinding and polishing device includes a workbench; a working frame is fixedly mounted at the top of the workbench, a first motor is arranged on the upper portion of the working frame, a sleeve is arranged on the lower portion of the working frame, and the bottom of the first motor is movably connected with a first rotating shaft; and the bottom end of the first rotating shaft penetrates through the middle of the top end of the working frame and is plugged into the sleeve, and the bottom end of the sleeve is fixedlyconnected with a clamping device. According to the supporting shaft interior and exterior grinding and polishing device used for the production and processing of the swivel chair, by arranging an interior grinding device and an exterior grinding device in a matched mode, the inner wall and the outer wall of the supporting shaft can be simultaneously ground, by arranging a sliding groove, a grinding rod, a control machine and an electric pushing rod, and the interior grinding device and the exterior grinding device can be adjusted for the supporting shafts of different sizes and propped on thesupport shafts for grinding.

Description

technical field [0001] The invention relates to the technical field of production and processing of swivel chairs, in particular to an internal and external grinding and polishing device for a support shaft used in the production and processing of swivel chairs. Background technique [0002] The swivel chair is one of the computer chairs and office chairs. It is a chair that can be rotated while sitting. The swivel chair is divided into two types: half swivel chair and full swivel chair. [0003] For the beauty and safety of the swivel chair, the support shaft supporting the rotation of the swivel chair needs to be ground and polished on the outer wall and the inner wall. Most of the traditional grinding and polishing devices can only polish the surface of the object, and the grinding device needs to move left and right to realize the surface of the object. Grinding is inefficient and consumes material resources. Some devices that can grind the inner wall of objects can only...
