The utility model discloses will be a plurality of straight swords are assembleed in together, are convenient for once only process the echelonment taper hole, improve production efficiency, improve the machining precision, the cost of charp tool is low, easy and simple to handle, and the cutting edge is for straight sword, handling ease.
Description
Technical field
The utility model relates to machining tool, particularly a kind of taper reamer.
Background technology
Reamer has one or more cutter tooth, in order to excise the rotary cutter of hole machined surface thin metal layer.The hole of reamer after reamer processing can obtain accurate size and dimension.The hole of reamer on ream workpiece after drilling (or reaming) processing, mainly in order to improve the machining accuracy in hole, reduce the roughness on its surface, be the fine finishining for hole and semi-finished cutter, allowance is generally very little.It is more conventional to be used for the reamer in processing column shape hole.The reamer being used for processing bellmouth is taper reamer, fewer use.Have hand reamer and chucking reamer by service condition, chucking reamer can be divided into straight shank reamer and taper-shank reamer again.Hand be then staight shank type.In existing production, the processing of taper hole needs taper reamer, and processing stepped taper hole needs the reamer changing different size to process it, and its machining accuracy is low, complex operation, production efficiency are low, the cost of charp tool is high.
Summary of the invention
For the deficiencies in the prior art, the purpose of this utility model is to provide a kind of taper reamer, and multiple straight sword set is in together, be convenient to the stepped taper hole of disposable processing, enhance productivity, improve machining accuracy, the cost of charp tool is low, easy and simple to handle, and blade is straight sword, handling ease.
The utility model solves the technical scheme that its technical problem adopts: described a kind of taper reamer, this reamer comprises: handle of a knife, be arranged on the cutter head of described handle of a knife head, it is characterized in that: described cutter head is made up of at least two blades, described blade is by the oblique sword of front end, continue after ladder sword composition, described blade circumference is distributed on bit interface, described blade extends along the axis direction of described cutter head, described ladder sword to join end to end and several the straight swords increased progressively highly successively form to cutter head afterbody by from cutter head head, the conical degree of conical surface that described straight sword mid point line is formed is 1:9, the taper ratio of described oblique sword is 1:9, direct chip discharging groove is provided with between described adjacent two blades, described handle of a knife afterbody is provided with chuck.
Multiple straight sword set in together, is convenient to the stepped taper hole of disposable processing, is enhanced productivity, improves machining accuracy, the cost of charp tool is low, easy and simple to handle by above-mentioned design, and blade is straight sword, handling ease.
As the better improvement of the design, described direct chip discharging slot cross-section is V-arrangement, and described direct chip discharging trench bottom is arc.Described direct chip discharging groove be V-arrangement and direct chip discharging trench bottom to be arc chip removal smooth, thermal diffusivity is good, not easily attaching liq in direct chip discharging groove, and edge strength is high, is convenient to carry larger cutting force.
As the better improvement of the design, described cutter head is carbide alloy.
As the better improvement of the design, described handle of a knife is carbon steel.
As the better improvement of the design, described handle of a knife is the international numerical control staight shank of Morse's taper Bing Huo.
As the better improvement of the design, described blade is 4.
The beneficial effects of the utility model are: multiple straight sword set in together, is convenient to the stepped taper hole of disposable processing, is enhanced productivity, improves machining accuracy, the cost of charp tool is low, easy and simple to handle by the utility model, and blade is straight sword, handling ease.
