Abstract

The utility model relates to the technical field of hardware and tools, and particularly relates to a broadening milling cutter. The broadening milling cutter provided by the utility model comprises a handle and a reamer, wherein a chamfering sleeve is arranged at the rear end of the reamer, the tail end of the chamfering sleeve is connected with the handle, a chamfering edge matched with the reamer is arranged at the front end of the chamfering sleeve, and the reamer, the chamfering sleeve and the handle are concentrically arranged. According to the broadening milling cutter provided by the utility model, as the reamer and the chamfering sleeve are integrally arranged, tool needs not to be changed for broadening and chamfering, and broadening, chamfering and moulding can be realized by one-time operation, thereby effectively improving the processing efficiency and the product precision.

Description

A kind of reaming milling cutter

Technical field

The utility model relates to hardware and cutting-tools technical field, particularly a kind of reaming milling cutter.

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 hole processing, generally need at present through punching, rough mill, the multiple working procedure such as finish-milling, chamfering, in process, need to change multiple cutter, exchange process is very loaded down with trivial details, affects production efficiency.

Utility model content

The purpose of this utility model is for the defect of prior art and deficiency, and a kind of reaming milling cutter simple in structure, easy to use is provided.

For achieving the above object, the utility model is by the following technical solutions:

A kind of reaming milling cutter described in the utility model, comprises handle of a knife and reamer, and described reamer rear end is provided with chamfering sleeve, and chamfering sleeve rear end is connected with handle of a knife, and chamfering sleeve front end is provided with the chamfering blades coordinating with reamer, and reamer, chamfering sleeve and handle of a knife arrange with one heart.

Further, described reamer rear end is provided with knife bar, and chamfering sleeve is sheathed on knife bar, knife bar tail end and handle of a knife be spirally connected and handle of a knife support be located on chamfering sleeve rear end.

Further, between described chamfering sleeve and knife bar, adopt pin to be connected.

Further, described chamfering sleeve is provided with holding screw, and holding screw and knife bar are spirally connected.

Further, the end diameter of described chamfering blades is less than reamer external diameter.

The utility model beneficial effect is: reamer of the present utility model and chamfering sleeve are wholely set, and perforate and chamfering are changed without tool changing, can a functions of reaming, chamfering moulding, effectively improve working (machining) efficiency and Product Precision.

Detailed description of the invention

Below in conjunction with accompanying drawing, the utility model is further described.

A kind of reaming milling cutter described in the utility model, comprise handle of a knife 1 and reamer 3, described reamer 3 rear ends are provided with chamfering sleeve 4, chamfering sleeve 4 front ends are provided with the chamfering blades 41 coordinating with reamer 3, reamer 3, chamfering sleeve 4 and handle of a knife 1 arrange with one heart, reamer 3 chamfering sleeve 4 after hole milling directly carries out chamfering to aperture, and a perforate completes chamfering process, improves working (machining) efficiency; Chamfering sleeve 4 rear ends are connected with handle of a knife 1, and handle of a knife 1 is for being fixed on main shaft fixture.

Above-mentioned reamer 3 rear ends are provided with knife bar 2, and chamfering sleeve 4 is sheathed on knife bar 2, and knife bar 2 tail ends and handle of a knife 1 are spirally connected and handle of a knife 1 supports and is located on chamfering sleeve 4 rear ends; Knife bar 2 adopts Split type structure with chamfering sleeve 4, and the chamfering sleeve 4 of conveniently replaced different angles, realizes different pore size reamer 3 and coordinate processing with the chamfering sleeve 4 of various angles.

Between above-mentioned chamfering sleeve 4 and knife bar 2, adopt pin to be connected, and then realize that chamfering sleeve 4 and knife bar 2 are coaxial is connected rotation.

Above-mentioned chamfering sleeve 4 is provided with holding screw, and holding screw and knife bar 2 are spirally connected, and then realizes that chamfering sleeve 4 and knife bar 2 are coaxial is connected rotation.

The end diameter of above-mentioned chamfering blades 41 is less than reamer 3 external diameters.

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.
