Ultra-high-speed rotating cylinder type permanent magnet polishing device

Abstract

The invention belongs to the technical field of magnetic grinding and polishing, and particularly relates to an ultra-high-speed rotating cylinder type permanent magnet polishing device. The ultra-high-speed rotating cylinder type permanent magnet polishing device is characterized by comprising a casing, a Tesla turbine, a container, a non-magnetic cylinder, a group of permanent magnets I and a group of permanent magnets II, wherein the Tesla turbine is arranged in the casing; the container is arranged at the upper part of the casing through a fixing frame; the non-magnetic cylinder is connected with an output shaft of the Tesla turbine; the group of permanent magnets I are fixed to the bottom of the non-magnetic cylinder through a magnetic metal plate; the group of permanent magnets II are fixed to the periphery of the non-magnetic cylinder through a magnetic conductive metal sheet; and the container is arranged inside the non-magnetic cylinder. Permanent magnet arrangement polishingand grinding machining is used; a still magnetic steel needle in the container is magnetized; along with the ultra-high speed rotation of the cylinder driven by the Tesla turbine, a generated rotatingmagnetic field is used for driving the steel needle to polish the surface of a workpiece; the Tesla turbine can exceed the upper limit of the speed of a used motor and reaches tens of thousands of revolutions per minute; and when the rotating speed is higher, the polishing efficiency of the cylinder type permanent magnet polishing device is higher.

Description

technical field [0001] The invention belongs to the technical field of magnetic grinding and polishing, and in particular relates to an ultra-high-speed rotary drum type permanent magnet polishing device. Background technique [0002] Surface quality problems such as burrs and scratches are unavoidable in the manufacturing process of mechanical parts. Traditional mechanical processing methods such as turning, milling, grinding wheel grinding, manual deburring, etc., are difficult to process the surface of small and complex parts. Even if they can be processed, they have disadvantages such as low efficiency, high cost, and high technical requirements for workers. The barrel type permanent magnet polishing device has advantages that traditional machining processes do not have. It can achieve high-quality and efficient finishing of the surface of small and complex parts. [0003] A relatively new cylindrical permanent magnet polishing device, such as the announcement case numb...

AI Technical Summary

Problems solved by technology

This method can achieve a good polishing effect, but due to the imperfect distribution of magnets, especially the distribution of magnetic poles around the container, a complete and dense closed magnetic force line loop cannot be formed, which affects the polishing effect and efficiency

In addition, the speed is directly proportional to the polishing efficiency. The upper limit of the driving speed of ordinary motors is 3000 rpm. If an ultra-high-speed motor is used, the efficiency is not high and the cost is high.
