Abstract
The utility model relates to a composite drilling-milling tool, which comprises a tool handle part and a blade part connected through a neck part; the blade part is provided with spiral cutting edges; the tool handle part is provided with a positioning neck; a drill bit is arranged at the bottom end of the blade part; two spiral cutting edges are provided; the spiral angles of the spiral cutting edges are 30-40 degrees; a drill point is formed at the top end of the drill bit; the drill point is connected with the spiral cutting edges through a drill abdomen; and a chip breaking notch is formed at the joint of the drill point and the drill abdomen. The composite drilling-milling tool has the beneficial effects that a milling tool can be arranged in a chuck of a main shaft of a numerical control machining center through the positioning neck on the tool handle part, so that the tool can be positioned; and drilling and milling functions are realized for the milling tool via the spiral cutting edges and the drill bit at the bottom of the blade part, the accuracy of workpieces is higher, and the smoothness is higher. A large spiral groove formed by the two cutting edges is more suitable for discharging machining chip smoothly. Drilling chip can be effectively broken by twisting through the chip breaking notch in a drill point opening, and is prevented from being wound on the tool.
Description
Technical field
The utility model relates to a kind of compound tool, particularly a kind of function of gathering multiple universal cutter of modern mechanical processing, applies to the compound brill milling cutter of auto parts and components manufacturing industry, hydraulic fluid manufacturing.
Background technology
Maximum in the machining is exactly the processing of hole system.The traditional handicraft machining hole is holed with fluted drill exactly, and what required precision was high also need carry out centralized positioning before boring, and the hole can not produce skew when could guarantee like this to bore, and next holes with fluted drill again.The hole that fluted drill gets out does not have required precision and fineness to require, and also needs to ream with milling cutter or reamer.The process that this traditional processing technology is finished the hole needs location, boring and three operations of milling, and technology is loaded down with trivial details, and relative efficiency is lower.Solve the problem of traditional handicraft inefficiency, must must using more, the more effective cutter of science solves.
The utility model content
The purpose of this utility model is that general cutter technology is loaded down with trivial details, the defective of inefficiency in order to solve in the prior art, provides a kind of compound brill milling cutter to solve problems of the prior art.
To achieve these goals, the technical solution of the utility model is as follows:
A kind of compound brill milling cutter comprises the tool shank and the blade that connect by neck, and blade is provided with the spiral cutting sword, and tool shank is provided with locating groove, and the blade bottom is provided with drill bit.
As preferred version, the spiral cutting sword has two, and its spiral angle is 30 °～40 °;
As preferred version, drill end is provided with apex point;
As preferred version, apex point connects the spiral cutting sword by boring abdomen;
As preferred version, apex point is provided with the chip breaking otch with the connecting portion that bores abdomen.
The beneficial effect that the utlity model has is: the locating groove by tool shank can be installed in milling cutter on the chuck of numerical control machining center main shaft, realizes the location of cutter.The drill bit of spiral cutting sword and blade bottom is realized the milling function by milling cutter when boring, make the precision of workpiece higher, and fineness is better.The king bolt groove of two cutting edge formation is more suitable for the smooth and easy discharge of processing bits.The chip breaking otch of apex point oral area position can effectively twist the bits that get out and break, and can not be wrapped on the cutter.The composite construction that the utility model cutter has is once finished the several steps of universal cutter, can improve the required precision that working (machining) efficiency can guarantee product again.
Description of drawings
Fig. 1 is the utility model structural representation.
Fig. 2 axially is rotated counterclockwise 90 ° of locating groove position views for Fig. 1.
Fig. 3 is Fig. 1 bit part structure enlarged diagram.
Among the figure: 1, tool shank, 2, blade, 3, the spiral cutting sword, 4, locating groove, 5, drill bit, 51, apex point, 52, bore abdomen, 53, the chip breaking otch.
The specific embodiment
Further understand and understanding for making architectural feature of the present utility model and the effect reached had, cooperate detailed explanation in order to preferred embodiment and accompanying drawing, be described as follows:
Shown in accompanying drawing 1,2 and 3: a kind of compound brill milling cutter, comprise the tool shank 1 and the blade 2 that connect by neck, blade 2 is provided with spiral cutting sword 3, tool shank 1 is provided with locating groove 4, and blade 2 bottoms are provided with drill bit 5, and spiral cutting sword 3 has two, its spiral angle is 35 °, drill bit 5 tops are provided with apex point 51, and apex point 51 connects spiral cutting sword 3 by boring abdomen 52, and apex point 51 is provided with chip breaking otch 53 with the connecting portion that bores abdomen 52.
The utility model cutter can be installed on the installation chuck of numerical control machining center main shaft, chuck folder tooth position being installed with portable, directly handle of a knife is put into chuck, handle of a knife is up pushed away, be stuck up to the detent mechanism of locating groove 4 with chuck inside, be that run into when pressing from both sides tooth positioned internal piece the handle of a knife bottom, put down folder tooth position again, location and installation has just been finished.Product just can have been processed after configuring the position that needs processing, the installation chuck of operating numerical control machining center makes milling cutter move quickly into general 1mm place, processing work surface, carries out drilling then slowly downwards, chip breaking otch 53 is disconnected the bits strand that gets out, and can not twine and have mercy on cutter.Spiral cutting sword 3 has only two and cutting edge sharp, and the king bolt groove of its formation can be discharged cutting swarf fast.Carry out milling again when drilling through workpiece, make the precision of workpiece higher, fineness is better.The whole process of apex point location, boring and milling is accomplished without any letup.Finish and upwards griffe after brill mills again, milling cutter moves quickly into the next position that processes after leaving the surface, repeats above-mentioned boring and milling process, like this, originally the processing technology of several steps has only just been finished with a step, has improved operating efficiency greatly, and can guarantee the quality of workpiece.
The nano coating processing is carried out on the utility model milling cutter surface, at milling cutter surface coverage last layer nano coating, can further prolong the service life of milling cutter.
In sum, it only is preferred embodiment of the present utility model, be not to limit the scope that the utility model is implemented, all equalizations of doing according to the described shape of the utility model claim scope, structure, feature and spirit change and modify, and all should be included in the claim scope of the present utility model.
