Description
Technical field
Patent of the present invention is related to machining research field, more particularly to a kind of interior cooling for cutting machines
Damping pyrocondensation cutter arbor device.
Background technology
At present, in High-speed machining industry, though common handle of a knife-collet-cutter formula tooling system structure can meet
The requirement of general part high-rate wireless LAN, but restricted so that cutter is caned close to workpiece when processing by tooling system rigidity
Depth be very restricted；Heat-shrinkable knife handle application ratio is wide, pyrocondensation knife bar with also tending to maturation.Carrying out at a high speed
During machining, heat in metal cutting can be communicated up along cutter, heat-shrinkable knife handle（Knife bar）The temperature of contact portion raises.Due to pyrocondensation
Handle of a knife（Knife bar）Cooperation with cutter is using pyrocondensation interference fit, heat-shrinkable knife handle（Knife bar）Thermal coefficient of expansion is larger, to temperature
Especially sensitive, temperature rising can cause heat-shrinkable knife handle（Knife bar）Contact portion size increases, and the magnitude of interference and cutter between reduces,
Contact stress reduces, and grip strength reduces, and then affects fit quality, brings serious accident.Joined to interference using traditional
There is very big deficiency, because interference areas temperature is not especially high, excessive use in the method closing area spray coolant
Cutting fluid not only increased cost, and its pollution causing is also very serious, does not meet current energy-saving and emission-reduction and green manufacturing
Trend.While High-speed machining, cutter also produces vibrations because of the impact of the factors such as cutting force.Accordingly, it would be desirable to it is a kind of new
Method solving above-mentioned technical problem.
Related invention a little examples, but be all very different with the present invention, in existing invention, such as Heilungkiang
The Wang Zhigang of No. 52 Harbin University of Science and Technologys in Harbin City of province Nangang District Universities Road；Xu Leida；It is " low in high precision that Cai Dongsong invents
Cost heat-shrinkable knife handle "（Number of patent application：CN201020273544.2, applying date 2010.07.28, disclosure/notification number：
CN201776646U, the disclosure/day for announcing：2011.03.30）High-precision low cost heat-shrinkable knife handle.With High Speed Cutting Technique
Extensive application and precision processing technology development, the requirement more and more higher to high-performance numerical control machine tool system.In high precision
Inexpensive heat-shrinkable knife handle, its composition includes：Taper shank (1), pyrocondensation head (2), described taper shank connects pyrocondensation head, in described pyrocondensation
It is machined with transitional pore (3), escape (4), stop screw hole (5), escape (6), pyrocondensation hole (7), the reduction of heat swollen groove of increasing in head
(8).Described transitional pore connects stop screw hole by escape, and described stop screw hole connects pyrocondensation hole by escape
Increase swollen groove with reduction of heat, described reduction of heat increases swollen groove and is opened on the hole wall in pyrocondensation hole.It is used for the connection of lathe and cutter, especially suitable
For accurate, high-speed machine tool.Its so-called reduction of heat, refers to reduce and cutter by the rectangular channel in heat-shrinkable knife handle inwall in fact
Contact heating surface area, because the requirement on machining accuracy of rectangular channel is high, can increase the manufacturing cost of handle of a knife using the method, contact
The reduction of area will also result in subtracting of grip strength and reduces and stress concentration, and rectangular channel can not change sinking path, heat
Amount still can be along contact surface fast propagation.
And for example Harbin, Heilongjiang Province Xiangfang District and No. 44 Harbin Measuring Tool ＆ Cutting Tool Co., Ltd. of level road
" dynamic balancing structure for thermal shrinkage shank " that Liu Xue invents and applies for a patent（Number of patent application：CN200720117397.8, the applying date：
2007.11.13, open (bulletin) number：CN201132265, open (bulletin) day：2008.10.15）.It includes main body, main body
For hollow structure, on body midsection circle of position week, dynamic balancing hole is equidistantly distributed with, is provided with dynamic flat in each dynamic balancing hole
Weighing apparatus screw.Pass through after Cutting tool installation manner to adjust the screw-in of dynamic balancing screw and the length of back-out, to adjust computing ballance correction, to eliminate cutter
The amount of unbalance producing is installed so as to the standard that reaches requires.So just can use at high speed.This heat-shrinkable knife handle can eliminate
The imbalance producing is installed, but does not solve the technical problems such as imbalance and vibrations that external force in High-speed machining is caused,
It is not involved with solving heat-shrinkable knife handle and the technical problems such as cutter cooling.
Content of the invention
The present invention is directed to the deficiencies in the prior art, it is an object of the invention to provide one kind can pass through pyrocondensation knife bar
Internal structure is quickly dredged heat, is reduced mating area temperature and absorb part vibrations and the preferably interior cooling damping heat of rigidity
Contracting cutter arbor device.
The technical solution adopted for the present invention to solve the technical problems is：It includes handle of a knife 5, pyrocondensation knife bar 3 and cutter 1；
The inner of handle of a knife 5 is the contour structures matching with machining center main shaft, and handle of a knife 5 is designed as hollow structure, and handle of a knife 5 is in hollow
Chamber waist is less than the screw vent structure matching with connecting screw rod 6 external diameter of two ends internal diameter for internal diameter, the outer end of handle of a knife 5 be to
The taper cavity structure opening outward；The inner profile of pyrocondensation knife bar 3 is the taper knot matching with handle of a knife 5 outer end taper cavity
Structure and the inner is provided with screw；The inner of pyrocondensation knife bar 3 is sleeved in the outer end taper cavity of handle of a knife 5, and using connection spiral shell
It is in mating connection that bar 6 is inserted in screw through the inner setting of screw vent and pyrocondensation knife bar 3 by handle of a knife 5 the inner, so that pyrocondensation
Knife bar 3 is fixedly connected with handle of a knife 5；The inner of cutter 1 is sleeved on pyrocondensation knife bar 3 outer end using interference seal cooperation；Described pyrocondensation
Knife bar 3 adopts hollow cavity structure, and the middle part of connecting screw rod 6 is provided with through hole and the sealing screw of the installation that matches with its through hole
9, the through hole of connecting screw rod 6 is connected with the hollow cavity of pyrocondensation knife bar 3, the pyrocondensation knife bar between connecting screw rod 6 and cutter 1
3 hollow cavities form cooling sap cavity 4, encapsulate coolant in cooling sap cavity 4.
By solving the technical problem that pyrocondensation knife bar is run into, pyrocondensation knife bar 3 of the present invention can, waist gradually little using two ends
Thicker biconial structure.
For improving radiating effect, the present invention also can be connected with radiating core 2 in cutter 1 the inner.Described radiating core 2 adopts heat conduction
