Abstract
The invention discloses a kind of drill mills, including shank section and blade part, shank section outer diameter is less than blade part outer diameter, blade part outer diameter is helical form, blade part outer diameter increases along helix, and blade part is equipped with the first symmetrical blade, the second blade and two dregs guiding grooves, the end face of first blade or the second blade is equipped with the first blade surface, second blade surface, third blade surface, the 4th blade surface, first blade surface is perpendicular to blade, second blade surface is to concave towards the cambered surface of blade, the first blade surface, the second blade surface, third blade surface, the 4th blade surface constitute the cross section of wedge shape.Drill mill of the present invention has both drilling, groove milling, the various aspects function such as rounded corner, during actual processing, can not tool changing tool once complete multiple processes, meet machining accuracy and high quality level, substantially increase processing efficiency.
Description
Technical field：
The present invention relates to a kind of drill mill, especially a kind of cutter head blade surface is trapezoidal drill mill.
Background technology：
In the processed and applied of industrial products, there are many places for needing drilling groove milling chamfering.In traditional technology, drilling need to be by work
Part frame is punched to drilling machine using drill, and work rest to milling machine need to be carried out groove milling, then have with tool changing by groove milling using milling cutter
Carry out chamfering；Also have and carry out drilling groove milling chamfering using brill milling one lathe or machining center, but also need to replace drill milling
Knife, and process compiler and also differ.The drill mill of new technology can merge drilling groove milling two procedures, but appoint and so cannot
Gather the function of chamfer rounded corner, this just needs a kind of knife of the novel groove milling chamfering three process that can be used to drill simultaneously
Tool, to further increase production efficiency.
Invention content：
It is an object of the invention to provide a kind of drill mills, solve one or more of the above-mentioned prior art problem.
In order to solve the above technical problems, the technical scheme is that：A kind of drill mill, including shank section and blade part,
Shank section outer diameter is less than blade part outer diameter, and blade part is helical form, and the outer diameter of blade part increases along helix, and blade part is equipped with pair
The end face of first blade of title distribution, the second blade and two dregs guiding grooves, the first blade or the second blade is equipped with the first blade surface, the
Two blade surfaces, third blade surface, the 4th blade surface, the first blade surface is perpendicular to blade, and the second blade surface is to concave towards the cambered surface of blade, the first sword
Face, the second blade surface, third blade surface, the 4th blade surface constitute the cross section of wedge shape.
Advantages of the present invention：Due to helically amplifying shape from handle of a knife to cutter head in structure, either bore, milling or chamfering
When, blade is all stable, and chip removal is smooth, and drilling groove milling chamfering three process set is completed, saves tool change time, significantly
Improve production efficiency.
Description of the drawings：
Fig. 1 is the lateral plan of drill mill of the present invention.
Fig. 2 is the positive direction view of cutter head blade surface of drill mill of the present invention.
Fig. 3 is the cutter head blade surface viewgraph of cross-section of drill mill of the present invention.
Illustrate in figure：1- handle of a knifes, 2- blades, the first blade surfaces of 2a-, the second blade surfaces of 2b-, 2c- third blade surfaces, the 4th swords of 2d-
Face, 3- dregs guiding grooves.
Specific implementation mode：
With reference to the accompanying drawings of the specification, the present invention is described in more detail.
A kind of drill mill as shown in Figure 1, including shank section 1 and blade part 2,1 outer diameter of shank section are less than outside blade part 2
Diameter, 2 outer diameter of blade part are helical form, and 2 outer diameter of blade part increases along helix, and blade part 2 is equipped with the first symmetrical blade,
The end face of second blade and two dregs guiding grooves 3, the first blade or the second blade is equipped with the first blade surface 2a, the second blade surface 2b, third
The blade surface blade surface 2a of 2c, the 4th blade surface 2d, first is perpendicular to blade, and the second blade surface 2b is the cambered surface for concaving towards blade, the first blade surface 2a,
Second blade surface 2b, third blade surface 2c, the 4th blade surface 2d constitute the cross section of wedge shape.
During actual processing, since the first blade surface 2a is smaller, drilling groove milling is had no effect on, in chamfer, is used
The 2c operations of third blade surface are operated in rounded corner using the second blade surface 2b, and the smooth no pause and transition in rhythm or melody granular sensation of fillet poured out meets
Quality requirement needed for production.
The scope of the present invention is defined by the appended claims and its equivalents.The above is only the present invention
Preferred embodiment, it is noted that those skilled in the art, do not depart from the invention design premise
Under, several similar modification and improvement can also be made, within these also should be regarded as protection scope of the present invention.
