Description

Automatic positioning and fixing mechanism for preventing local deformation of large grinding tool

Technical Field

The utility model relates to a grinding apparatus fixed equipment technical field, especially an automatic positioning fixed establishment who prevents large-scale grinding apparatus local deformation.

Background

Abrasives are tools used for grinding, lapping and polishing. Most of the grinding tools are artificial grinding tools made of grinding materials and bonding agents, and also natural grinding tools directly processed by natural ore rocks are used. Grinding tools are widely used in the machinery and other metal processing industries, but also in grain processing, paper industry and the processing of non-metallic materials such as ceramics, glass, stone, plastics, rubber, wood, etc. When the grinding tool is used and the grinding particles are dull, the grinding particles partially or completely fall off from the grinding tool due to the fact that the grinding particles are partially cracked or the bonding agent is broken, and new cutting edges or new sharp grinding particles are continuously exposed on the grinding material on the working surface of the grinding tool, so that the grinding tool can keep cutting performance for a certain time. The self-sharpening property of the grinding tool is the outstanding characteristic of the grinding tool compared with a common cutter. The grinding tools are classified into natural grinding tools and artificial grinding tools according to the raw material sources. The only natural abrasive used in the mechanical industry is oilstone. The artificial grinding tools are distinguished according to basic shape and structural characteristics and comprise five types, namely grinding wheels, grinding heads and oilstones, and sand tiles are generally called consolidation grinding tools and coated grinding tools. In addition, abrasives are also customarily classified as a class of abrasive articles. When the grinding tool works, the grinding tool needs to be fixed, the grinding tool fixing equipment still has development space, how to improve the shock absorption performance can enable the grinding tool to work better, meanwhile, the service life of the grinding tool can be prolonged, and the grinding tool fixing device with the shock absorption function needs to pay attention to and develop. There is a great need for a grinding tool fixing device with a damping function, which can connect a motor and a grinding tool, and under the rotation of the motor, the grinding tool can perform cutting operation, and when the grinding tool just contacts an article to be ground, the connecting plate can drive the grinding tool to generate certain displacement, so that the vibration and damage of the grinding tool are reduced, and the grinding tool can work better.
