Description

technical field [0001] The invention mainly relates to the technical field of magnetic grinding, in particular to an automatic fine grinding device for the outer surface of a shaft workpiece. Background technique [0002] In the industrial fields of machinery, electromechanical, and electric facilities, shaft workpieces, such as round shafts, screw screws, and straight pipes, are widely used in industrial equipment. With the increasing intelligence and integration of industrial equipment, higher requirements are placed on the stability and service life of the equipment. For shaft workpieces, the higher the accuracy of the outer surface, the higher the accuracy of the outer surface and other connecting parts. The more precise the coordination, the stronger the fatigue strength, reliability and corrosion resistance, which can improve the stable operation time of industrial equipment and provide the foundation and guarantee for the development of industrial equipment.

AI Technical Summary

Problems solved by technology

[0004] 1. When the grinding wheel grinding head is used to grind the outer surface of the shaft workpiece, the grinding wheel grinding head is in direct contact with the shaft workpiece, and the positioning accuracy of the grinding head and the shaft workpiece to be ground is required to be very high. The structure of the grinding machine is complex and requires professional operation, and the grinding cost High, when grinding shaft workpieces of different specifications, the operation and adjustment are more complicated and inefficient

[0005] 2. After the grinding wheel is worn, it will affect the grinding effect, and the grinding wheel is easy to be found and adjusted only when the degree of wear is relatively large, resulting in a decrease in the grinding accuracy of the outer surface of the shaft workpiece

[0006] 3. The grinding wheel grinding head of the grinding machine adopts a fixed grinding head to grind the outer surface of the shaft workpiece. The vibration generated by the grinding machine and the failure of the grinding head will interfere with the accuracy of the outer surface of the shaft workpiece, and the grinding progress is difficult to further improve.
