Problems solved by technology

The existing problem is that there are many kinds of materials that need to be polished in current production and life, and the shapes of materials are also different.
And in most cases, the appearance of the object to be polished is irregular. Ordinary grinding machines cannot grind the depressions, which cannot meet our production and living needs, and sometimes damage the grinding machine and grinding materials, making it impossible to achieve correct grinding. Optimal Allocation of Raw Materials

Abstract

The invention provides a stiffness-adjustable grinding device and a using method. The stiffness-adjustable grinding device comprises a motor for providing power; a switch used for controlling the motor to start is mounted on the motor; a grinding wheel or a grinding belt used for grinding is mounted on an output shaft of the motor; a grinding area on the grinding wheel or the grinding belt is divided into a plurality of layers by adopting a rubber material; the intermediate layer adopts a hydraulic layer or a pulse layer which can produce instantaneous acting force; the remaining layers are the stiffness layers that can provide different grinding stiffness; the hydraulic layer or the pulse layer are respectively connected with a hydraulic device or a pulse device correspondingly; a convexstructure used for enhancing a grinding effect is arranged on the surface of the grinding wheel and the grinding belt; the outer surface of the convex structure is wrapped with a flexile material layer; and by changing the grinding material of the stiffness layer in real time, the object can be polished by fine adjustment of appropriate stiffness. Compared with a common grinding device, the stiffness-adjustable grinding device has wider practicality and economic benefits, and better meets the grinding requirements required by production and living.

Description

technical field [0001] The invention relates to the technical field of object grinding and polishing, and is mainly used for grinding objects with different rigidities so as to improve the existing grinding technology. Background technique [0002] Grinding is a kind of surface modification technology. It generally refers to a processing method that uses rough objects (sandpaper with higher hardness particles, etc.) to change the physical properties of the material surface through friction. The main purpose is to obtain a specific surface roughness. Polishing refers to the use of mechanical, chemical or electrochemical action to reduce the surface roughness of the workpiece to obtain a bright and smooth surface. The purpose of its work is to remove the burrs on the surface of the product workpiece, so that it is easy to continue processing or reach the finished product. It is a modification process on the surface of the workpiece by using polishing tools and abrasive partic...
