Abstract
The utility model relates to the technical field of hardware cutting tools, in particular to a multiple-blade reamer. The multiple-blade reamer comprises a handle. An arbor is arranged at the front end of the handle, and is sleeved with a plurality of facing cutters with different external diameter, a connecting pin is arranged between the arbor and the facing cutters, and a fixing screw nut is arranged at the end of the arbor. The multiple-blade reamer is simple in structure; the facing cutters with different caliber are arranged on the arbor to form a step-by-step facing cutter structure to realize processing multiple stepped appearance counter bores in one step so that processing accuracy and production efficiency are improved. The multiple-blade reamer is reasonable in structure, flexible in dismounting and can effectively reduce labor intensity and production cost.
Description
Technical field
The utility model 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.
Utility model content
The purpose of this utility model is for the defect of prior art and deficiency, provide a kind of simple in structure, use multiple-cutting-edge reamer flexibly.
For achieving the above object, the utility model is by the following technical solutions:
A kind of multiple-cutting-edge reamer described in the utility model, 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.
The utility model beneficial effect is: the utility model 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 are improved, rational in infrastructure, dismounting is flexible, can effectively reduce labour intensity and production cost.
Brief description of the drawings
Fig. 1 cuts open structural representation in entirety of the present utility model.
In figure: 1, handle of a knife; 2, facing cutter; 3, centring ring; 4, hold-down nut;
11, knife bar; 12, connecting pin.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is further described.
A kind of multiple-cutting-edge reamer described in the utility model, 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 utility model, and the equivalence of doing according to structure, feature and principle described in the utility model patent claim therefore all changes or modifies, and is included in the utility model patent claim.
