Extrusion-honing clamp for drill point

Abstract

The invention provides an extrusion-honing clamp for a drill point. The extrusion-honing clamp comprises a drill point which is to be subjected with extrusion honing, an upper transition plate, a lower transition plate, an abrasive runner plate, an abrasive runner upper cover plate, abrasive runner side surface cover plates, a flat work piece clamp and a work piece clamping V-shaped groove, wherein the abrasive runner plate is fixedly arranged on the lower transition plate; the abrasive runner upper cover plate is fixedly arranged on the abrasive runner plate; the abrasive runner side surface cover plates are fixedly arranged at the two sides of the abrasive runner plate and the abrasive runner upper cover plate; the upper transition plate is used for covering the abrasive runner upper cover plate and the abrasive runner side surface cover plates; the drill point which is to be subjected with extrusion honing is clamped in a groove between the work piece clamping V-shaped groove and the flat work piece clamp. An abrasive fluid medium in a through hole is repeatedly extruded by upper and lower pistons of a honing machine so that the abrasive fluid medium can be fully processed in a flowing manner on the surface of a needle head. The extrusion-honing clamp disclosed by the invention has the advantages of realizing noncontact loading of a drill in honing, realizing damage-free honing of the drill, improving the surface quality of the drill and also obviously increasing the amount of clamped cutters to 50.

Description

technical field [0001] The invention relates to the field of machining, in particular to a drill honing fixture installed on a honing machine. Background technique [0002] Extrusion honing technology is to achieve deburring, polishing, chamfering and changing the surface properties of parts in one process by extruding semi-solid fluid abrasives (composed of polymer carriers and abrasives) through the surface of the workpiece to be processed. It can process multiple surfaces of multiple workpieces at the same time, and can efficiently and economically process surfaces with complex geometric shapes such as narrow slits, intersecting channels, and special-shaped surfaces. The use of extrusion honing instead of manual polishing can greatly reduce labor intensity, improve productivity, and ensure the consistency of product processing. At the same time, extrusion honing has high efficiency, good quality, simple equipment and convenient operation. [0003] At present, drills are...
