Abstract

The invention discloses a broaching tool for machining a rifling of an inner hole of a small-caliber gun barrel. The broaching tool comprises a clamping mechanism and a broaching mechanism, wherein the broaching mechanism is detachably arranged on the left side of the clamping mechanism; the clamping mechanism comprises a first flange plate and a positioning column, wherein the first flange plateis circular; and an inner cavity of the positioning column is rectangular, the positioning column is fixedly connected to the left side of the first flange plate, and four first screw holes are formedin the outer wall of the positioning column in the circumferential direction. According to the broaching tool, a wire pulling cutter rod can be disassembled and mounted, so that the wire pulling cutter rods with different diameters can be conveniently replaced, and then the rifling of the gun barrel with different inner diameters can be broached; and in addition, a plurality of tools can be mounted, so that the rifling of the gun barrel can be broached at a time, time and labor are saved, the practicability is high, and the rifling of the small-caliber gun barrel can be conveniently broached.

Description

Technical field[0001]The present invention relates to the field of tool techniques, specifically a scaling tool for processing small-diameter artille fittings.Background technique[0002]The artillery tube line processing technology generally has a process method such as squeezing, pulling, electrolysis processing. The squeezing line is suitable for shallower lines, mostly used in the barrel processing of the barrel. At present, the domestic artillery industry is mainly used by mechanical pull-down and electrolysis, and the medium-sized diameter multi-purpose pull-down method, the small-diameter artillery tube line generally uses electrolysis processing. Due to some factory-free processing equipment, and lack of processing experience, it is necessary to design a special tool system on the basis of enterprise existing equipment to achieve the processing of small-diameter artillery tube line;[0003]For small-diameter artillery tube ribs, currently, it is a single-knife pull, often need t...
