Abstract

The invention provides a magnetorheological jet polishing device and a circulation system provided with the same. Magnetorheological jet liquid is loaded by adopting a method of an eccentric hopper, the eccentric hopper and a magnetic field generating assembly or the center of a nozzle are eccentric, a stirring assembly is added into the eccentric hopper, a lateral spraying port is loaded on the side face of the eccentric hopper, so that the spraying port can spray the magnetorheological jet liquid or special gas or water, thus stirring of magnetorheological jet liquid can be achieved, at thesame time, liquid flushing on the eccentric hopper wall can be achieved, performance retention of the magnetorheological jet liquid can be achieved by injecting the special gas, and auxiliary cleaningof the magnetorheological jet liquid can be achieved through lateral water spraying. In addition, auxiliary parameter detection such as water cooling channel, pressure detection and temperature detection is additionally conducted on the device, parameter control of the circulation system is achieved, and accordingly stable circulation of the magnetorheological jet liquid is achieved.

Description

technical field [0001] The invention relates to the field of magnetic jet polishing, in particular to a magnetic jet polishing device and a circulation system with the device Background technique [0002] Magnetic jet polishing technology (Magnetorheological Jet Polishing, MJP) is obtained by replacing the liquid in traditional liquid jet processing technology (Fluid JetPolishing, FJP) with magnetorheological fluid (Magnetorheological Fluid). Liquid jet polishing itself is a kind of flexible polishing technology, which relies on the liquid containing abrasives to be sprayed out by high pressure to scour the surface of the component to remove the material, but it is difficult to achieve high stability of the ejected jet beam. Magnetic jet polishing technology utilizes low-viscosity magnetorheological fluid to have a rheological effect in an external magnetic field, and the apparent viscosity increases to significantly increase the stability of the jet beam, thereby achieving ...
