Abstract
The invention relates to a dual-end inner-hole boring cutter. The dual-end inner-hole boring cutter comprises a cutter shank, a first boring cutter end and a second boring cutter. The first boring cutter end and the second boring cutter end are respectively arranged at both ends of the boring cutter, wherein the first boring cutter end comprises a first extension round bar and a first cutting edge which is mounted on the first extension round bar and the second boring cutter end comprises a second extension round bar and a second cutting edge which is mounted on the second extension round bar. The axis of the first extension round bar is not in the same line with the axis of the second extension round bar. The dual-end inner-hole boring cutter is reasonable in structure and applicable to boring inner holes. According to this arrangement, materials expenses and time for changing cutters can be saved. The ends of the boring cutter can be reused by proper mould repair upon wearing out, and accordingly, the service life of the coring cutter is improved and the cost is saved.
Description
Technical field
The present invention relates to hardware and cutting-tools technical field, particularly a kind of double end inner hole boring tool.
Background technology
Boring cutter is the one of cutting tool for boring, is generally circle handle, also has the larger workpiece user knife bar generally to see vertical car, the most frequently used occasion be exactly in hole process, reaming, profiling etc.But be not hole in can only processing, the outer fenestra of end face can be processed.There is one or two cutting tip, be specifically designed to roughing, semifinishing or accurately machined cutter are carried out in existing hole.Boring cutter can use on boring machine, lathe or milling machine.
But in prior art, inner hole boring tool comprises handle of a knife and is arranged at the hilted broadsword head of described handle of a knife one end, cutter head has blade, but this type of inner hole boring tool is owing to being hilted broadsword header structure, in use, often need frequent better cutter head to adapt to workpiece process requirements, and save tool changing, need to expend many time, to working (machining) efficiency, bring harmful effect, and after long-term use, very easily there is wear phenomenon in cutter head, the cutter head after wearing and tearing cannot secondary utilization.
Summary of the invention
The object of the invention is to defect and deficiency for prior art, a kind of double end inner hole boring tool that possesses Double-cutter head, saving fee of material and save tool change time is provided.
For achieving the above object, the present invention is by the following technical solutions: a kind of double end inner hole boring tool, described double end inner hole boring tool comprises handle of a knife and is arranged at the first boring cutter head at described handle of a knife two ends, the second boring cutter head, described the first boring cutter head comprises the first extension round bar and is arranged at first blade of described first extension round bar one end, described the second boring cutter head comprises the second extension round bar and is arranged at described second and extend second blade of round bar one end, described first extend round bar with the axis of described the second extension round bar not on same straight line.
Further, described the first blade or the second blade comprise in turn the first side, Second Edge, the 3rd limit and the 4th limit that connect, and when described handle of a knife is during in level, described first side is in level.
Further, the angle that the Y-axis of described Second Edge and vertical direction forms is 45 °.
Further, the angle that the Y-axis of described the 3rd limit and vertical direction forms is 12 °.
Further, the angle that the X-axis of described the 4th limit and horizontal direction forms is 27 °.
Further, the angle direction pointed defining between described the 3rd limit and described the 4th limit is that edge bends is pointed to, and the edge bends of described the first blade is pointed to the edge bends of described the second blade and pointed to each other in the other direction.
Further, described first extends be connected with described the first blade position and/or described the second extension round bar position that is connected with described the second blade of round bar and is formed with arc-shaped transition portion.
Further, the side of described handle of a knife is comprised of an arcwall face and a screw installed surface, and described screw installed surface is plane.
Beneficial effect of the present invention is: double end inner hole boring tool of the present invention is rational in infrastructure, for boring endoporus, and its dual head design, save fee of material and save tool change time, after the wearing and tearing of boring cutter head, only need suitably repair a die and can again normally use, improve service life, cost-saving.
