Description

Abrasive particle flow tool Technical Field The utility model relates to the technical field of tool fixtures, in particular to an abrasive particle flow tool. Background Abrasive flow machining (Abrasive Flow Machining, AFM) is an advanced surface treatment technique that achieves precision polishing, deburring and chamfering by flowing a semi-solid abrasive medium through the surface of a workpiece under pressure. The technology utilizes the visco-elastic fluid abrasive to cut the workpiece in a micro-scale under the drive of pressure, thereby obviously improving the surface quality. The core advantage of abrasive particle stream processing is its ability to handle complex structures. The method can be used for efficiently processing parts which are difficult to access by the traditional process, such as deep holes, cross holes, inner cavities and the like, and is widely applied to the fields of aerospace, automobile manufacturing, medical appliances and the like. When the workpiece is subjected to abrasive flow machining, the workpiece is limited and fixed through a tool. However, when the aperture of the tool feed hole is not matched with that of the workpiece, the flow speed of the abrasive entering the inner hole of the workpiece and the pressure generated on the hole wall of the workpiece are unstable, so that the processing effect is affected. Therefore, workpieces with different apertures are usually limited by separate tools, so that the cost is high and the applicability is poor.
