Abstract
The utility model discloses a combined numerical control milling cutter which consists of a cutter body and a cutter handle. The cutter body and the cutter handle are connected in a combined manner of hot charging connection and threaded connection. An axial inner hole of a step is arranged at the end head of the main body of the cutter handle for interference fit with a pin and a threaded pin of the cutter body. The combined numerical control milling cutter is suitable for chipping with great allowance and heavy load chipping due to good installation rigidity.
Description
Technical field
The application relates to digital control processing field, particularly a kind of Combined-type numerical control milling cutter.
Background technology
In NC Machining Process, the application of numerical control machining cutter is very important, directly affects working (machining) efficiency, quality and production cost.For numerical control machining cutter, the reliability that cutter hub is connected with handle of a knife is very crucial.At present, in NC Milling Cutter, hot charging connected mode and thread connecting mode are comparatively common cutter hub and handle of a knife connected modes.
Hot charging connected mode is generally used for the connection of solid carbide, utilizes expanding with heat and contract with cold of handle of a knife to realize the clamping to cutter, has the features such as Knife handle structure is simple, volume is little, is particularly suitable for high-speed milling processing.
Thread connecting mode is to utilize the threaded engagement of cutter hub and handle of a knife to realize to be connected, be generally used for modular cutter hub and handle of a knife be connected, be characterized in cutter hub miniaturization, modularization, only a need replacing cutter head just can be realized the change of tool specification, has reduced the cost of charp tool.
But, in long-term application, can find, these two kinds of connected modes have certain weak point.Particularly, in some large surplus cuttings, heavily loaded working angles, the rigidity that cutter hub is connected with handle of a knife is not enough, affects surface quality and the efficiency of large surplus cutting, heavy duty cutting.In addition, hot charging connected mode also exists cutter hub installation length to be difficult to the problem of accurately controlling.
Summary of the invention
The application's object is to provide a kind of Combined-type numerical control milling cutter, and the connection of cutter hub and handle of a knife is by being connected in conjunction with hot charging and the advantage of the two kinds of modes that are threaded, and increases end face location structure, realizes cutter hub and handle of a knife more firmly, be connected accurately.
A kind of Combined-type numerical control milling cutter, contain cutter hub and handle of a knife, it is characterized in that described cutter hub is comprised of blade and connecting portion, it between blade and connecting portion, is a coaxial large diameter positioning step, connecting portion contains with blade with the pin of diameter and the threaded of minor diameter, the end face of handle of a knife has axial inner bore of step, and this inner bore of step mates with pin and the threaded of cutter hub, and ecto-entad is followed successively by counterbore, screwed hole.
At cutter hub and handle of a knife, install while being connected, first with the connecting portion of cutter hot charging machine heating handle of a knife, make it to expand, its inner bore of step diameter increases, again the threaded of cutter hub is screwed in the screwed hole of handle of a knife, until the connecting portion end face of cutter hub positioning step and handle of a knife is fitted completely, install and complete after cooling, for processing.
When needs dismounting or replacing cutter hub, with the connecting portion of hot charging machine heating handle of a knife, then cutter hub is screwed out to handle of a knife, cooling rear dismounting completes.
The application, by the combination connecting mode that adopts hot charging to connect and be threaded, has higher clamping rigidity than simple hot charging connected mode and thread connecting mode, and connection reliability is higher; By increasing cutter hub positioning step, increased end face after cutter hub is installed and fitted tightly, further strengthened installation rigidity; Meanwhile, the present invention has also overcome the problem that traditional cylindrical bar milling cutter installation length can not accurately be controlled.This combination CNC milling cutter, due to good rigidly being installed, is adapted to large surplus cutting, heavy duty cutting.
Below in conjunction with embodiment accompanying drawing, this invention is described in further detail:
Accompanying drawing explanation

Number description: 1 cutter hub, 2 handle of a knifes, 3 blades, 4 positioning steps, 5 pins, 6 threadeds, 7 counterbores, 8 screwed holes, 9 connecting portions, 10 shanks.
Specific embodiment
The present embodiment provides a kind of combination CNC milling cutter that adopts hot charging thread connecting mode.
As Fig. 1, this combination CNC milling cutter is comprised of cutter hub 1 and handle of a knife 2.
It is cylindric that cutter hub is totally, and as Fig. 2, blade 1 and connecting portion, consists of.Cutter hub blade is cylindric, is the cutting tip of cutter hub, identical with the blade of common solid carbide, and its diameter and length need and determine according to reality processing.Between cutter hub blade and connecting portion, be a coaxial large diameter positioning step 4, positioning step is cylindrical, and length is shorter, and diameter is greater than diameter at edge part, plays end face positioning action.Cutter hub connecting portion contains with blade with the pin 5 of diameter and the threaded 6 of minor diameter.Pin is straight pin shape, and diameter equals diameter at edge part.Threaded is cylindrical thread shape, and its diameter is less than pin auxiliary section diameter.Cutter hub material is whole hard alloy.
Handle of a knife 2 is comprised of shank 10 and connecting portion 9.As Fig. 3, handle of a knife is comprised of shank 10 and connecting portion 9.Shank 10 is normal structure, meets general international standard, and as HSK handle, BT handle, JT handle etc., realization is connected with machine tool chief axis.Handle of a knife connecting portion 10 is the part being directly connected with cutter hub 1, at the end face of handle of a knife, is provided with axial inner bore of step, and this inner bore of step mates with pin 5 and the threaded 6 of cutter hub, and ecto-entad is followed successively by counterbore 7, screwed hole 8.
The counterbore of handle of a knife and screwed hole with pin and the coordinating of threaded connecting portion of cutter hub are interference fit.
When cutter hub 1 is connected with handle of a knife 2, first with cutter hot charging machine, heat the connecting portion 9 of handle of a knife 2, make it to expand, its inner bore of step diameter increases, again the threaded of cutter hub 16 is screwed in the screwed hole 8 of handle of a knife 2, until cutter hub positioning step 4 is fitted completely with the connecting portion end face of handle of a knife, cooling rear installation completes, for processing.
When needs dismounting or replacing cutter hub, with the connecting portion 9 of hot charging machine heating handle of a knife 2, then cutter hub 1 is screwed out to handle of a knife, cooling rear dismounting completes.
