A clamping device for drill honing

Abstract

The invention discloses a clamping device for honing drill bits. The clamping device comprises a left workpiece clamp, a right workpiece clamp, a left fixed seat, a right fixed seat and two abrasive transition plates, wherein the left and right workpiece clamps are attached to each other; clamping grooves for clamping tail shanks of drill bits to be machined are formed between the left and right workpiece clamps; the left workpiece clamp, the right workpiece clamp, a left fixed block and a right fixed block are integrally fixed through cylindrical screws; the left and right workpiece clamps clamp the drill bits through clamping screws; the two abrasive transition plates are fixedly arranged at the upper and lower ends of the left and right fixed seats, and form an vertically communicated inner cavity with the left and right fixed seats; the heads of the drill bits to be machined are positioned in the inner cavity. The clamping device is simple and compact in structure and low in production cost; a drill bit extrusion honing technology is used for machining, so that the surface roughness of the drill bits is reduced, the surface quality of the drill bits is improved, and the drill bits can be honed without damage.

Description

technical field [0001] The invention relates to a drill bit clamping device, more specifically, to a clamping device for honing a drill bit by using an abrasive fluid medium with a certain pressure and flow rate. Background technique [0002] A drill is a tool used to drill through holes or blind holes in solid materials and to ream existing holes. Commonly used drills mainly include twist drills, flat drills, center drills, deep hole drills and casing drills. [0003] Extrusion honing technology, also known as abrasive flow processing technology, is a new surface polishing and deburring process in modern times, which has a good effect on the polishing and deburring of molds and parts. Squeeze honing is a smoothing method that uses abrasive flow media (viscous abrasives) with a certain pressure and flow rate for honing. It is mainly used to improve some inner holes, curved small holes, cross surfaces, cross holes and irregular opposite The processing quality of the inner a...
