Description
Technical Field
The utility model designs a processing device for polishing an inner hole and a surface of a brake bracket by liquid two-phase flow.
Background
The abrasive flow machining technology is a latest machining method, and is characterized in that an abrasive medium flows through the surface to be machined of a workpiece under pressure to perform deburring, deburring and rounding angles so as to reduce the waviness and roughness of the surface of the workpiece and achieve the finish of precision machining;
the abrasive grain flow polishing mechanism mainly takes abrasive grains in the abrasive material as a cutting tool, and uses irregular sharp edges and corners of the abrasive grains to repeatedly cut the working surface of a part through which the abrasive material flows, so that the polishing and deburring of the surface of a workpiece are realized. When the abrasive grain is processed in a flow mode, the viscoelastic medium is regarded as a carrier of hard abrasive grains, the abrasive grains are ground with the processed surface of the workpiece, and the viscoelastic medium can be regarded as a spring mechanism, so that excessive collision between the abrasive grains and the surface of the workpiece can be buffered, and micro cracks are avoided. The abrasive flow processing is hardly limited by the geometric shape of the workpiece, can be used for deburring and finishing the surfaces of planes, inner and outer surfaces of round tubes, spiral surfaces, complex curved surfaces or micro-hole flow channels, and can effectively improve the surface quality of the workpiece.
