Polishing abrasive tool, polishing device comprising polishing abrasive tool, and polishing method

Abstract

The invention provides a polishing device. The polishing device comprises a rotary pedestal, a polishing abrasive tool, a positioning jig and a swing mechanism; the polishing abrasive tool is arrangedon the rotary pedestal and the polishing surface is upward; the polishing surface is provided with a spiral groove and an avoiding groove which is positioned in the center position of the spiral groove; the positioning jig is positioned above the polishing abrasive tool and comprises a vertical jacking rod and a product placing table which can be rotationally arranged at the lower end of the jacking rod; the positioning jig cooperates with a pressure load mechanism in order to closely press a product on the polishing surface of the polishing abrasive tool; the swing mechanism comprises a power source and a double-crank mechanism; one end of the double-crank mechanism is connected with the power source; and the other end of the double-crank mechanism is connected with the jacking rod so asto realize synchronous motion of the two ends. The invention further provides a method for polishing by utilizing the polishing device; and the rotary pedestal and the double-crank mechanism cooperate with each other to realize 360-degree self-rotation motion and periodic circular motion of a to-be-machined surface of the product on the polishing surface of the polishing abrasive tool, thereby guaranteeing that each position of the product is polished uniformly and the polishing surface is abraded uniformly.

Description

technical field [0001] The invention relates to the technical field of polishing ceramics, precious stones and glass materials, in particular to a polishing abrasive, a polishing device containing the polishing abrasive, and a polishing method for processing ceramic products by using the polishing device. Background technique [0002] With the rapid development of science and technology, ceramics, gemstones, glass and other materials are more and more widely used. In order to meet the needs of different industries for the above-mentioned materials, the corresponding processing technology has also been continuously innovated.

Problems solved by technology

At present, when polishing the product surface, the most used method is to use a brush to polish with a polishing solution, but this method is more suitable for products with ordinary structures such as large flat surfaces, and for products containing stepped surfaces, concave-convex surfaces, and chamfered edges. Products with special structures, such as low polishing efficiency and poor polishing effect, are prone to defects such as over-throwing collapse or impenetrable polishing during the process of polishing step surfaces, concave-convex surfaces, and chamfering with brushes

[0003] This is because: 1. The brush is made of soft material, and the force it generates on the product surface will change due to the change of its own compression and extrusion degree, resulting in uneven structural pressure in products with special-shaped structures such as stepped surfaces and concave-convex surfaces. The problem of uniformity makes the product unable to achieve uniform polishing everywhere

2. Even if the shape of the brush is designed to be convex, concave or other corresponding special-shaped structures, the brush itself, which is a soft material, will produce obvious deformation once it is squeezed, which still cannot solve the polishing problem caused by uneven structural pressure

[0005] However, this type of polishing abrasive also has the following problems: the traditional hard polishing tool has a phenomenon that the edge part wears fast and the middle part wears slowly due to the high linear velocity of the edge and the small linear velocity of the middle part, while the wear degree of the polishing tool at different positions The difference on the surface will lead to poor uniformity of the processed product, reducing the service life and processing quality of the abrasive tool
