Multi-station bar polishing tool

Abstract

The invention discloses a multi-station bar polishing tool which comprises a rack. A first driving shaft and a first driven shaft which are parallel to each other are arranged on the rack. The first driving shaft is connected with a first drive motor. The periphery of the first driving shaft and the periphery of the first driven shaft are sleeved with a first sanding belt. A second sanding belt is arranged above the first sanding belt in parallel. The second sanding belt is driven by a second driving shaft and a second driven shaft to move. The second driving shaft is connected with a second driving motor. A fixture used for allowing bars to be embedded therein is arranged between the opposite faces of the first sanding belt and the second sanding belt. The rotating direction of the first driving shaft is opposite to that of the second driving shaft. The multi-station bar polishing tool is simple in structure; the multiple bars are placed in the fixture between the first sanding belt and the second sanding belt so that the multiple bars can be polished at the same time; and compared with operation that a bur is handheld to be clamped between polishing wheels in the prior art, the safety coefficient is high.

Description

technical field [0001] The invention relates to polishing equipment, in particular to a multi-station rod polishing tool. Background technique [0002] High-speed tungsten steel dental burs are divided into two types: welded type and integral type according to the material of the working part and the shank; the working part of the welded tungsten steel bur is made of tungsten steel, and the shank is made of steel or stainless steel, which are welded; The shank of the integral tungsten steel working part is made of integral tungsten steel. Since the bur has no weld seam, it does not turn around or deform during processing or clinical use. It has extremely high concentricity, no swing, stable rotation, no damage to the mobile phone, and no vibration for the patient feel. High-speed tungsten steel dental burs are processed by precision CNC machine tools, with fine blade teeth, and can be made into complex blade teeth burs of various specifications. Dental burs will have small...

AI Technical Summary

Problems solved by technology

Dental burs will have tiny defects on the surface after processing and molding, which need to be polished and cleaned by a polishing machine to improve the brightness of the product. Currently, burs are generally polished manually. Due to the small size of dental burs, it is not convenient for manual work. It is inconvenient to hold and polish, and the efficiency of manual polishing is low, and the polishing effect is poor

[0003] The improved technology uses two polishing wheels to move oppositely to clamp the bur for polishing, but the above-mentioned polishing is suitable for a single bar, and the polishing efficiency is low
