Continuous grinding mechanism based on grinding belt surface self-growth

Abstract

The invention discloses a continuous grinding mechanism based on grinding belt surface self-growth. The continuous grinding mechanism based on the grinding belt surface self-growth comprises a grinding belt, a water tank, an abrasive particle injector head, a UV light lamp tube, a workpiece installing head, a double-directional cylinder and a base station; the water tank is filled with UV light solidified coatings, an idler wheel is installed in the water tank, two idler wheels which are higher than the water tank are installed on two sides of the water tank, when the grinding belt moves, the grinding belt firstly enters the water tank, after the grinding belt moves out of the water tank and moves to be horizontal, the surface of the grinding belt is covered with the UV light solidified coatings, and grinding belt surface self-growth is conducted; the abrasive particle injector head is installed above the horizontal position of the grinding belt, the UV light lamp tube is installed on the back face of the abrasive particle injector head, and the height of the workpiece installing head can be adjusted through the double-directional cylinder, the height can be maintained until workpiece machining is completed. By means of the structure, restoration of the grinding belt is simple, fast and convenient, dismounting of the grinding belt is not needed, the restoration of the grinding belt and the workpiece machining can be conducted synchronously, and the surface of the restored grinding belt is flatter and neater.

Description

technical field [0001] The invention relates to the field of grinding / polishing, especially the field of ultra-precision grinding / polishing. Background technique [0002] Ultra-precision grinding and polishing is a main processing method in the field of ultra-precision machining. Ultra-precision grinding and polishing developed in recent years is a method that can realize high-precision and high-quality processing of advanced material workpieces. Ultra-precision grinding and polishing is generally divided into grinding and polishing with grinding belt and grinding and polishing with grinding belt. When applying pressure on the workpiece mounting head, the grinding belt moves at a constant speed, so that there is relative movement between the workpiece and the fixed grinding belt for grinding to complete the grinding process. Compared with abrasive belt processing, abrasive belt processing can process multiple workpieces at the same time, and can process a wider range of wor...

Problems solved by technology

[0004] Using the traditional method to repair the grinding belt, it is necessary to disassemble the grinding belt, so that the workpiece cannot be processed further, and because the hardness of the grinding belt is soft, the wear speed is faster than that of the grinding belt, so the repair of the grinding belt is more frequent; at the same time, when using the traditional method , when the grinding belt is trimmed with an electroplated diamond correction wheel, it will cause excessive dressing due to insufficient hardness of the grinding belt, which will cause the grinding belt to become thinner or even damaged
