Abstract
The invention relates to the technical field of metal cutters, in particular to a multi-edge reamer comprising a shank. A tool bar is arranged at the front end of the shank. The tool bar is sequentially sleeved with a plurality of milling cutters different in outside diameter. A connecting pin is arranged between the tool bar and the milling cutters. A fastening nut is arranged at the tail end of the tool bar. The multi-edge reamer is simple in structure; the tool bar is provided with the multiple milling cutters different in diameter to form the stepped milling cutter structure; multiple stepped counterbores can be made once; machining precision and production efficiency are improved; the multi-edge reamer is reasonable in structure and flexible to disassemble, and labor intensity and production cost can be effectively decreased.
Description
Technical field
The present invention relates to hardware and cutting-tools technical field, particularly a kind of multiple-cutting-edge reamer.
Background technology
Machining generally comprises car, plane, milling, brill, mill etc., various processing modes all have different processing technologys and special cutter, wherein common hardware and cutting-tools comprises lathe tool, milling cutter, planing tool, fluted drill etc., to meet different products and processing request.In processing for notch cuttype counterbore, the multiple working procedures such as general needs pass through and punch, rough mill, finish-milling, need to change multiple cutter in process at present, and exchange process is very loaded down with trivial details, also can cause the decline of machining accuracy.
Summary of the invention
The object of the invention is to defect and deficiency for prior art, provide a kind of simple in structure, use multiple-cutting-edge reamer flexibly.
For achieving the above object, the present invention is by the following technical solutions:
A kind of multiple-cutting-edge reamer of the present invention, comprises handle of a knife, and described handle of a knife front end is provided with knife bar, is arranged with successively the different facing cutter of some external diameters on knife bar, between knife bar and facing cutter, is provided with connecting pin, and the end of knife bar is provided with hold-down nut.
Further, described knife bar is provided with some centring rings, and centring ring is arranged between the facing cutter of arbitrary neighborhood.
Further, between described centring ring and facing cutter, be provided with connecting pin.
The external diameter of the some facing cutters that are socketed on described knife bar further, increases progressively successively.
Beneficial effect of the present invention is: the present invention is simple in structure, the facing cutter of multiple different bores is set on knife bar, composition echelon facing cutter structure, can realize the multistage trapezoidal counterbore of time processing, machining accuracy and production efficiency have been improved, rational in infrastructure, dismounting is flexible, can effectively reduce labour intensity and production cost.
Accompanying drawing explanation
Fig. 1 cuts open structural representation in entirety of the present invention.
In figure: 1, handle of a knife; 2, facing cutter; 3, centring ring; 4, hold-down nut;
11, knife bar; 12, connecting pin.
The specific embodiment
Below in conjunction with accompanying drawing, the present invention is further illustrated.
A kind of multiple-cutting-edge reamer of the present invention, comprise handle of a knife 1, described handle of a knife 1 front end is provided with knife bar 11, on knife bar 11, be arranged with successively the different facing cutter of some external diameters 2, on knife bar 11, the external diameter of some facing cutters 2 of socket increases progressively successively, the facing cutter 2 of various outer diameter is processed respectively the shoulder hole position of different size, knife bar 11 is provided with some centring rings 3, centring ring 3 is arranged between the facing cutter 2 of arbitrary neighborhood, centring ring 3, for controlling the depth location of facing cutter 2, is realized the requirement of the shoulder hole of flexible combination processing different depth size.
Between above-mentioned knife bar 11 and facing cutter 2, be provided with connecting pin 12, between centring ring 3 and facing cutter 2, be provided with connecting pin 12, by connecting pin 12, facing cutter 2 and centring ring 3 are realized to the radial location on knife bar 11, and the connecting key that the moment of torsion between connecting pin 12 or facing cutter 2 and knife bar 11 transmits, be used for avoiding facing cutter 2 to skid on knife bar 11, the end of knife bar 11 is provided with hold-down nut 4, and hold-down nut 4 is for being fixed on knife bar 11 by some facing cutters 2 and centring ring 3 series connection.
The above is only preferred embodiments of the present invention, and the equivalence of doing according to structure, feature and principle described in patent claim of the present invention therefore all changes or modifies, and is included in patent claim of the present invention.
