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
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.
