Problems solved by technology

[0004] 1) The drill pipe and drill bit in the existing taper drill are generally integrated design, which is not easy to disassemble. When the drill pipe or drill bit is seriously worn during use, it cannot be replaced in a targeted manner, and the entire taper drill is often replaced. Replacement, increase the cost of use;
[0005] The milling inserts of the existing taper drills cannot be disassembled, and the inserts can only mill holes with one precision, so the scope of use is narrow, and the hardness of the taper drills is relatively poor, which is extremely susceptible to wear and affects its service life

Abstract

The invention discloses a hard alloy indexable taper drill and a machining method thereof. The hard alloy indexable taper drill comprises a drill rod, a drill bit, a tool apron and a blade. The drilling device has the beneficial effects that a positioning column, a positioning groove, a clamping rod, a fastening bolt, a threaded hole and a clamping groove are matched, a drill rod and a drill bit can be fixed, the fixing mode is simple, and when the drill bit or the drill rod is damaged, a pressing block is pressed, so that the pressing block compresses a first movable block; the first movable block extrudes the clamping rod in the clamping groove, so that the clamping rod is separated from the clamping groove, the drill bit is detached, and the drill bit or a drill rod is convenient to replace; the blade is provided with the finish-milling blade and the rough-milling blade, the finish-milling blade and the rough-milling blade are both provided with the anti-rust coatings, the corresponding blades can be conveniently selected according to actual drilling, the drill rod and the drill bit are both made of hard alloy materials, the hardness of the taper drill can be improved, and then the service life of the taper drill is prolonged.

Description

technical field [0001] The invention relates to a taper drill, in particular to a cemented carbide indexable taper drill and a processing method thereof, belonging to the technical field of milling cutters. Background technique [0002] A milling cutter is a rotating tool with one or more teeth for milling. Each tooth is equivalent to a turning tool fixed on the rotating surface of the milling cutter. The cutting edge that participates in cutting at the same time during milling is longer. And there is no empty stroke, and it is also high, so the productivity is high. There are many types of milling cutters, different structures, and a wide range of applications. There are three major categories of milling cutters, milling cutters of general specifications have been standardized, and are generally produced by professional tool factories, and taper drills are also a type of tool. [0003] And existing taper drill has some problems when using: [0004] 1) The drill pipe and d...
