Magnetic-abrasive finishing machine and method for circular-conical-surface oblique groove

Abstract

The invention relates to the technical field of magnetic-abrasive finishing of circular-conical-surface workpieces, in particular to a magnetic-abrasive finishing machine and method for a circular-conical-surface oblique groove. The magnetic-abrasive finishing machine comprises a machine tool base, a machine tool spindle box, a three-jaw chuck, a tool holder moving device, a lifting device, a rotating device, a polishing device and a PLC system. The tool holder moving device is fixedly connected to the machine tool base; the lifting device is fixedly connected to a moving platform of the toolholder moving device; the tool holder moving device drives the lifting device to do linear movement in the transverse direction and the longitudinal direction; the rotating device is fixedly connectedto the lifting device; the lifting device drives the rotating device to go up and down; the polishing device is fixedly connected to the rotating device; the rotating device drives the polishing device to rotate; a to-be-machined workpiece is clamped to the three-jaw chuck; and the PLC system is electrically connected with a machine tool spindle motor, the tool holder moving device, the lifting device, the rotating device and the polishing device. The specific surfaces of the circular-conical-surface oblique groove and the like can be effectively machined; the machining efficiency is improved; and the grinding and polishing quality is improved.

Description

technical field [0001] The invention relates to the technical field of magnetic grinding of conical surface workpieces, in particular to a magnetic grinding machine and method for oblique grooves on conical surfaces. Background technique [0002] With the rapid development and continuous progress of the machinery manufacturing industry, conical surface parts can be used more and more widely, especially for valve components in pipeline systems, the relatively high sealing specific pressure of the conical surface under the action of axial force is often used. Features to improve sealing. However, when the surface quality of the two conical parts that cooperate with each other is poor, it will cause the medium in the pipeline to leak out, which will not only cause material loss, pollute the environment, and even cause accidents in serious cases; for flammable, explosive, toxic or radioactive Medium is not allowed.

However, when the surface quality of the two conical parts that cooperate with each other is poor, it will cause the medium in the pipeline to leak out, which will not only cause material loss, pollute the environment, and even cause accidents in serious cases; for flammable, explosive, toxic or radioactive Medium is not allowed

[0003] In traditional surface grinding, turning tools are usually used to process the surface, but due to the small processing surface, it is difficult for turning tools to process it effectively. Traditional processing technology is difficult to ensure that the surface quality of parts meets the requirements of finishing. Wrinkles, pits, and micro-cracks will grow on the inner surface, resulting in unstable mechanical work and reduced power
