According to the gas-liquid-solid abrasive flow feeding device, a cavity in the three-phase mixing mold is set to be a quincunx shape, the characteristic that the inner surface of the quincunx is large is utilized, and the cavity is matched with a rotary nozzle arranged on a solution medium jet orifice, so that three-phase abrasive flows are mixed more evenly, and the mixing flow and polishing properties of the abrasive flows are improved. An abrasive particle feeding device is set to be suspended, the property of feeding abrasive flows can be further improved, flow rate control valves are arranged for all media, the controller can be adjusted according to actual ratio needs, and proportioning of abrasive flow mixed liquid of various ratios is achieved.

Description

technical field [0001] The invention relates to the technical field of abrasive flow polishing high-precision machining, in particular to a gas-liquid-solid three-phase abrasive flow supply device. Background technique [0002] Final finishing in the manufacture of precision parts is a labor-intensive and difficult-to-control process, which can sometimes account for as much as 15% of the total manufacturing cost. The abrasive flow processing technology is an automatic finishing method that can guarantee precision, efficiency and economy, and is an effective method to solve the final finishing of precision parts. It uses a certain pressure to force the viscoelastic material containing abrasives to pass through the surface to be processed, and uses the scraping effect of the abrasive grains to remove the microscopic uneven materials on the surface of the workpiece to achieve the purpose of finishing the surface of the workpiece. Abrasive flow processing technology is an advan...
