Magnetic-repulsion automatic constant-pressure feeding device

Abstract

The invention belongs to the field of mechanical grinding and discloses a magnetic-repulsion automatic constant-pressure feeding device. The magnetic-repulsion automatic constant-pressure feeding device comprises a base, a magnetic-repulsion feeding mechanism arranged on the base, a driving mechanism for driving the magnetic-repulsion feeding mechanism to move, and a constant-pressure feeding control system for controlling the driving mechanism to act. Through a principle that magnets with the same polarity are mutually repulsive, mutual repulsion between a front moving base and a moving base is controlled by controlling positions of a front magnet and a back magnet and the distance therebetween in real time; the mutual repulsion directly acts on a grinding tool through a workpiece, so that the workpiece can be fed flexibly at a constant pressure; and the magnetic-repulsion automatic constant-pressure feeding device is small in frictional torque, flexible in movement, high in transmission efficiency, high in precision, simple in structure and convenient to operate.

Description

technical field [0001] The invention relates to the field of mechanical grinding, in particular to a magnetic repulsion force automatic constant pressure feeding device. Background technique [0002] The constant pressure feed device is widely used in the field of mechanical grinding, such as precision grinding machine tools, wear ratio testers, etc. At present, the constant pressure feeding device is mainly realized by hydraulic method (hydraulic cylinder) and mechanical method (spring, lever). The main disadvantage of using hydraulic cylinder to realize constant pressure feed is that the damping of the relative motion between the various components of the hydraulic system is large, the force transmission is complicated, the response is slow, and the constant pressure control of small feed cannot be accurately realized. The constant pressure feeding method realized by mechanical devices such as springs and levers has a complex mechanical structure, inaccurate pressure cont...
