Abstract

An ultrasonic composite high-pressure airflow magnetic grinding device and method are characterized in that the device comprises an installation platform (6); a synchronous belt guide rail (7) is installed at one end of the installation platform (6); a sliding block (8) is installed on the synchronous belt guide rail (7); an ultrasonic vibrator (1) is installed on the sliding block (8); a cylinder workpiece (3) is installed on the ultrasonic vibrator (1); a bent plate support (5) is installed at the other end of the installation platform (6); a hollow motor (34) for driving the polishing main shaft assembly (4) to rotate is fixed to the bent plate support (5); and high-pressure airflow enters the hollow rotating shaft (16) through a rotating joint and enters a machining area through holes which are communicated with one another. According to the device, the effect of multiple physical fields is compounded; the grinding track of abrasive particles is more complex and uniform; and the device is reasonable in design, simple in structure, high in machining efficiency and easy to adjust and assemble.

Description

Technical field[0001]The present invention relates to the field of ultrasonic assistance magnetic abrasive techniques, and more particularly to magnetic abrasive devices and methods of a cylindrical inner wall ultrasonic composite high pressure gas stream.Background technique[0002]The rapid development of modern manufacturing has made higher requirements for precision optical finishing technology, so magnetic grinding technology is born. The magnetic abrasive forms a magnetic brush under the action of the magnetic field, generating vibration, reciprocation, and rotation through an external force, so that the abrasive is scratched and impact on the surface of the workpiece, thereby achieving flexible finishing of the workpiece. At present, the magnetic field is mainly produced by electromagnet or permanent magnet. However, the electromagnetic coil structure is complex and severely heated, and the strong magnetic field of permanent magnet is difficult to produce a certain extent, the ...
