Description
Technical field
Patent of the present invention is related to high-speed milling finishing research field, more particularly to a kind of for milling equipment
High flexibility knife bar can be combined.
Background technology
With the extensive use of high-rate wireless LAN technology and the development of precision processing technology, to high-performance numerical control milling machine work
The requirement more and more higher of tool system, therefore all start to use handle of a knife-pyrocondensation knife bar-cutter formula tooling system knot on many lathes
Structure, handle of a knife-pyrocondensation knife bar-cutter formula tooling system is simple in construction, clamping force is big, the cutting moment of torque is big, radial positioning precision is high, footpath
It is strong to rigidity height, cushioning ability, also deep-small hole structure can be processed well；But the size tolerance requirements of pyrocondensation knife bar are tight
Lattice cause its manufacturing cost very high, and manufacturing process is complicated, strict to material requirements, and pyrocondensation knife bar can only be to the knife of same diameter
Tool is clamped.For a diameter of 1 ~ 3mm small-diameter cutter, it is more obvious that pyrocondensation knife bar displays manufacture drawback.Cause
This is, it is necessary to which a kind of new method solves above-mentioned technical problem.
The content of the invention
It is an object of the invention to provide a kind of combined high flexibility knife bar, by pyrocondensation knife bar or steel knife bar and cutter
Between the heat expansion folder cylinders of the higher different diameter of bores of the coefficient of expansion is installed, so as to carry out high intensity to different-diameter milling cutter
Clamping, improve flexibility of the milling cutter in pyrocondensation knife bar front end and exchange.This device does not change the self structure of tooling system, because
This has very strong applicability.
The technical solution adopted for the present invention to solve the technical problems is：It includes steel knife bar 1, heat expansion folder cylinder 2, milling
Cutter 3, the inside of steel knife bar 1 are stair-stepping hollow structure, and one end is the short taper profile structure coordinated with handle of a knife 4, and the other end is
The long pyramidal structure being engaged with heat expansion folder cylinder 2, heat expansion folder cylinder 2 one end is through-hole structure, and milling cutter 3 is filled by thermal shrink fit
In the through hole for entering heat expansion folder cylinder 2.
Triangle thread is provided with the both ends inner ring surface of steel knife bar 1, heat expansion folder cylinder 2 one end is machined with and steel knife bar
1 screw thread being engaged, heat expansion folder cylinder 2 are tightened against on steel knife bar 1 by screw thread, and attachment screw 5 and steel are provided with handle of a knife 4
The screw thread of knife bar 1 is in mating connection.
The outer end of steel knife bar 1 is long taper or cylindrical structural, and its taper is 0 ~ 4 degree, to reduce itself and workpiece
Interference.
Stair-stepping hollow structure is processed into inside the steel knife bar 1 to reduce its weight, improves its rigidity.
It is threaded inside the steel knife bar 1.
The steel knife bar 1 is using the preferable alloy material of rigidity.
The heat expansion folder outer end anchor ring of cylinder 2 is threaded.
The inside of heat expansion folder cylinder 2 is through-hole structure, its a diameter of 1 ~ 6mm.
The heat expansion folder cylinder 2 is using the higher Cu alloy material of the coefficient of expansion.
The milling cutter 3 is using the relatively low wolfram steel material of the coefficient of expansion, in order to its clamping in heat expansion presss from both sides cylinder 2.
The beneficial effects of the invention are as follows：The cooperation that cylinder and steel knife bar are pressed from both sides by heat expansion is pressed from both sides to milling cutter front end high intensity
Hold, because steel knife bar manufacturing cost is more much lower than pyrocondensation knife bar, the heat expansion folder cylinder of different diameter of bores can clamp different-diameter
Milling cutter, thus the specifications and models of knife bar can be reduced, applicability is good.
Meanwhile the milling cutter in the present invention is good by using standard component, interchangeability；Heat expansion press from both sides cylinder by fastening thread with
Steel knife bar connects, simple and reliable for structure, and heat expansion folder cylinder Seriation Design is applicable to the cutter of different-diameter, and steel
Knife bar will not be destroyed substantially in process, and one steel knife bar of installation is more much lower than using the cost of pyrocondensation knife bar.
