Abstract

The invention discloses an abrasive flow machining device capable of cleaning sharp edges and burrs at annular grooves in deep holes. The device comprises a frame support structure consisting of a base plate (1), a support plate (2) and a cover plate (3), wherein a base plate counter bore (4) and a cover plate counter bore (5) which are arranged towards the outer side are formed in the base plate (1) and the cover plate (3) respectively, a base plate through hole (6) and a cover plate through hole (7) are formed in centers of the base plate counter bore (4) and the cover plate counter bore (5) respectively, a pipe joint (8) penetrating through the base plate through hole (6) is inversely buckled in the base plate counter bore (4), a flow guide rod (9) penetrating through the cover plate through hole (7) is inversely buckled in the cover plate counter bore (5), a work piece (10) is arranged between the pipe joint (8) and the flow guide rod (9), an upper passing hole (11) and a lower passing hole (12) are formed in the flow guide rod (9) and the pipe joint (8) respectively, and flow guide pieces (13) are arranged at one end of the flow guide rod (9). According to the abrasive flow machining device, the problems that the burrs at the annular grooves in the deep holes cannot be cleaned with a traditional manual deburring method and machining cannot be performed on the sharp edges of the annular grooves in the deep holes are solved.

Description

technical field [0001] The invention relates to an abrasive particle flow processing device, in particular to an abrasive particle flow processing device for cleaning sharp edges and burrs at ring grooves of deep holes. Background technique [0002] Abrasive flow machining is a processing method in which abrasives suspended in a semi-solid medium with viscoelasticity directly rub against the surface of the workpiece under a certain extrusion force to cut and polish the surface. Therefore, the rational design of the flow channel is the key to achieve the ideal effect of AFM, and in most cases, the reasonable establishment of the flow channel is realized by the fixture. [0003] The existing abrasive flow fixture has no effective cleaning method for the sharp edges and burrs at the ring groove of the deep hole. As we all know, the cutting effect of the abrasive is strong when it passes through the variable load surface and the turning position. If no tooling is used during ab...
