Abstract

Provided is a drilling and milling cutter with an orifice chambering function. The utility model relates to the technical field of a cutting tool used in hole machining on solid materials. The drilling and milling cutter with the orifice chambering function solves the technical defects that an existing cutting tool used in the hole machining on the solid materials is single in function, complicated in machining processes, and low in production efficiency. The drilling and milling cutter with the orifice chambering function comprises a drilling body and a drilling handle, the handle diameter of the drilling handle is larger than the blade diameter of the drilling body, and the tail end of the drilling body is connected with the front end of the drilling handle through a cone-shaped transition section. The drilling and milling cutter with the orifice chambering function is characterized in that a chambered cutting blade which is used for chambering an opening of a straight hole is arranged on an inclined face on the cone-shaped transition section, wherein the opening of the straight hole is drilled and milled through the drilling body. The drilling and milling cutter with the orifice chambering function not only has a function of a drilling cutter and can drill the straight hole, but also has a function of a milling cutter. The chambered cutting blade on the inclined face on the cone-shaped transition section can be used for chambering the existing straight hole. The drilling and the milling cutter with the orifice chambering function is multifunctional, cutter spacing is reduced, chambering can be conducted directly after the straight hole is machined and finished, the process is completed smoothly, and working efficiency is improved.

Description

A kind of brill milling cutter with orifice chamfer function
Technical field
The utility model relates on the solid material hole machining and uses the cutting-tool engineering field, is specifically related to the drilling of straight hole and the chamfering cutter for same aspect in aperture.
Background technology
In the process of solid material hole, often need on entity, drilling go out the straight hole of a perforation, and need to carry out chamfering in the aperture of straight hole, present implementation at first is that the brill cutter drilling by as shown in Figure 1 goes out a straight hole, and then with taper mill shown in Figure 2 the orifice edge of this straight hole is cut, reach the effect of chamfering; There is complex procedures in present this implementation, needs at least to use one piece of brill cutter and one piece of milling cutter, and two corresponding cutter spacing need be set, and production efficiency is low.
Summary of the invention
In sum, the purpose of this utility model is to solve on the existing solid material that the hole machining is single with tool function, and manufacturing procedure is complicated, the technical deficiency that production efficiency is low, and a kind of brill milling cutter with orifice chamfer function is proposed.
Proposed technical problem by solving the utility model, the technical scheme of employing is: a kind of brill milling cutter with orifice chamfer function includes drill body and drillstock; The handle footpath of described drillstock is greater than the sword footpath of drill body, and the tail end of drill body is connected with the drillstock front end by a tapering transition section; It is characterized in that: be provided with the chamfered cutting edge that chamfering is carried out in the straight hole aperture that goes out for the drilling to drill body on the inclined-plane of described tapering transition section.
The inclined-plane of described tapering transition section is provided with three spiral chamfered cutting edges.
Described drill body and drillstock are the integrative-structure of wolfram steel material.
Described drillstock is step handle or positioning handle.
The beneficial effects of the utility model are: the utility model not only has the cutter of boring function, can drilling go out straight hole, also has simultaneously the milling cutter function, can carry out chamfering to existing straight hole with the chamfered cutting edge on the inclined-plane of tapering transition section, one cutter is multiplex, reduces cutter spacing, machines at straight hole and can directly carry out chamfering, accomplish without any letup, promote operating efficiency.
Description of drawings
Fig. 1 is the existing knife structure schematic diagram that bores;
Fig. 2 is the existing milling cutter construction schematic diagram that is used for chamfering;
Fig. 3 is structural representation of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing and the preferred specific embodiment of the utility model structure of the present utility model is further described.
Shown in Fig. 3, the utility model includes drill body 1 and drillstock 2; The handle footpath of described drillstock 2 is greater than the sword footpath of drill body 1, and sword footpath size determines the straight hole pore size of drilling, and the tail end of drill body 1 is connected with drillstock 2 front ends by a tapering transition section 3; Be provided with chamfered cutting edge 31 on the inclined-plane of described tapering transition section 3, finish the processing of straight hole when drill body 1 after, continue to advance the utility model, chamfered cutting edge 31 will carry out chamfering to the straight hole aperture of finishing, the straight hole orifice edge is cut.For stressed even in the chamfer process, the inclined-plane of described tapering transition section 3 is provided with three spiral chamfered cutting edges 31.Described drill body 1, drillstock 2 and tapering transition section 3 are the integrative-structure of wolfram steel material.In order to increase the intensity of handle of a knife 2, described handle of a knife 2 can be the step handle; Stability in order to install is avoided skidding, and described handle of a knife 2 can also be positioning handle, that is to say that handle of a knife 2 is provided with locating slot.
