Description

Main shaft structure of polishing machine

Technical Field

The utility model relates to a high-accuracy mechanical equipment's technical field especially relates to a burnishing machine main shaft structure.

Background

The quality of the polishing process directly influences the attractive quality, the appearance smoothness and the quality precision of products, the polishing process is a very key process, and the polishing machine serving as polishing equipment is widely applied to surface processing of 2D and 2.5D glass, sapphire, ceramic, metal and other hard and brittle materials. The main shaft structure of the polishing machine is an important component of the polishing machine and becomes an important link of the design of the polishing machine.

However, the spindle of the existing polishing machine needs to be pressurized by an external cylinder guide rail structure, so that the occupied space is large, and the spindle structure is unstable in pressurization during rotary polishing, so that the transmission is unstable, and the polishing quality is seriously influenced.

Disclosure of Invention

For overcoming the defects of the prior art, the to-be-solved technical problem of the utility model is to provide a polishing machine main shaft structure, its compact structure, occupation space are little, the transmission is steady.

The technical scheme of the utility model is that: according to the main shaft structure of the polishing machine, a cylinder body (4) and a cylinder liner plate (3) are fixed on a main shaft fixing seat (1), a linear bearing (2) is fixed on the inner hole surface of the main shaft fixing seat (1), a piston shaft (6) is connected with a polishing disc assembly (A), and the polishing disc assembly is driven to move up and down under the support of the linear bearing (2) to realize pressurization.

The utility model discloses a cylinder block and cylinder backing plate are fixed on the main shaft fixing base, and linear bearing fixes on the downthehole face in the main shaft fixing base, and the piston shaft is connected and is thrown aureola subassembly to drive throwing aureola subassembly up-and-down motion under linear bearing supports and realize the pressurization, place the main shaft in the cylinder in, compact structure, occupation space are little, the transmission is steady.
