Description

A kind of lathe for processing screw
Technical field
The present invention relates to a kind of lathe, more particularly, to a kind of lathe for processing screw, belongs to machine-building skill Art field.
Background technology
So far, the processing of large-scale marine propeller substantially adopts following several schemes:1st, first by the every of screw Individual blade and wheel hub disassemble it is separately machined, then by each part assembling use.The screw that this mode is processed due to Structure is limited, and its symmetry and rigidity are all under some influence, and repeatedly installs there is accumulated error in addition, and reliability compares monoblock type Screw is poor.2nd, using the interlocked numerical controlled milling machine of portal-type multi-shaft, screw is fixed on the workbench in the middle of column, is processed Reprocessing another side is overturn behind upper surface, finally using a small amount of hand finish.This processing method needs multiple clamping The processing of whole screw can be just completed, argosy airscrew diameter, weight make more greatly its upset and clamping all relatively difficult, And multiple clamping has resetting error, the accuracy of manufacture of screw is affected;In addition, propeller blade root is mostly curved Shape, there is overlapping region, and the interference of lathe, cutter and screw and collision problem cannot be fully solved always in process.3、 The method combined using abrasive belt grinding machine and manual grinding is processing screw.Grinding is the finishing operation of general process, The finishing of part is completed, surface quality is also preferable.The operation principle of abrasive belt grinding machine is to workpiece by the quick rotation in abrasive band It is ground and is polished, but due to current abrasive band and grinding characteristic theoretical research and sbrasive belt grinding complex surface machining technology also not Enough maturations, the structure for adding sbrasive belt grinding itself is limited so as to the grinding of more suitable monomer blades.Although manual polishing The overall grinding and buffing of screw can be completed, but machining accuracy depends on the technical merit and qualification of workman, work Bad environments, high labor intensive is affected larger by the subjective destabilizing factor of people, and less efficient.For argosy spiral shell Rotation oar upset is difficult and again clamping brings resetting error, Zhao Hu et al. in the Patent No. of application in 2009 200910038368.6《Six-axis five-linkage propeller machining center》Patent and Zhang Shengwen et al. are in the patent of application in 2012 Number for 201210233126.6《Double power head screw dedicated numerical control specialized nc machine tool and processing method》Patent is adopted respectively With screw it is laterally disposed come avoid overturning and make machine tool structure compact and using upper and lower two sets of drill head system clamped one times just The processing of whole screw can be completed, working (machining) efficiency is improve and is alleviated labour intensity, to large-size propeller machining tool Design provides certain directive function.With the development of ocean engineering and defending for sovereignty over territorial waters, argosy is used both at home and abroad The research and development of propeller processing lathe are also deepening continuously.At present, the great Han precision optical machineries company of Korea have developed and can add The marine propeller equipment of a diameter of 11 meters of work, model HPMC-110 is can to process airscrew diameter maximum in the world at present Equipment.The lathe adopts planer type structure, Z axis tiltable to be conducive to the processing of screw overlapping region.It has the disadvantage can not The upper and lower surface and planer type structure for processing screw simultaneously also has an impact to the rigidity of machine tool.The country, by Wuhan heavy machine tool collection Co., Ltd of group undertakes, " the screw weight that the Central China University of Science and Technology, Zhenjiang Zhongchuan Wartsila Propeller Co., Ltd. research and develop jointly Type sevenfive axis turning-milling complex processing lathe ", by appraisal of scientific and technological achievements, with the control of seven axles, five-axle linkage turnning and milling The functions such as Compound Machining, on-line measurement, are capable of achieving to screw blade face lap, non-overlapped part, blade profile and oar Comprehensive precision milling processing of the machining areas such as hub mesopore, processes diameter of up to 8.5 meters, and extension is reachable 12.5 meters, highly up to 3.3 Rice.Its defect is can not be simultaneously to the two-way processing in screw two sides, and working (machining) efficiency is not ideal enough.In addition, planer type structure in order to Improve the rigidity of machine tool and increase construction weight so that lathe is overall excessively clumsy.
In view of various research approaches above, the processing of large-scale marine propeller is mostly using cascaded structure formula lathe. The advantage of cascaded structure is that each axle motion of lathe is separate, and motion control is simple, and Technical comparing is ripe, and working space is big, spirit Activity is good.But serial machine tool is open-chain structure, there is cantilever section, not only bears Tensile or Compressive Loading but also also subject to bending load, In order to improve the rigidity of system, the weight of component must be increased so as to which dynamic performance is poor, while also constraining feed speed Increase substantially.In addition, each link deflection and junction deflection are superimposed so that between cutter and workpiece in serial machine tool Relative motion error be usually the linear superposition of each coordinates of motion, there is accumulated error.However, parallel institution is exactly to string Online bed beneficial complement, it has high rigidity, high bearing capacity, high speed, low inertia, advantages of simple structure and simple, does not exist Serial mechanism accumulated error problem, spatial pose fulfillment capability is strong, is particularly easy to realize six-axis linkage, be very suitable for aviation, Space flight, automotive field complete complex-curved processing, such as blade, impeller, screw, and representational is NEOS companies of Sweden Tricept series parallel machines, have been successfully applied on the production line of automobile, aircraft.The characteristic that parallel institution shows is caused It is especially suitable for processed complex curved surface part and high in machining efficiency, good processing stability.It there is also defect, such as position forecast Complexity, numerical control programming is complicated, and working space is little etc..
Large-scale marine propeller is typical complex-curved thin wall component, and blade root and wheel hub junction are more narrow, leaf There is overlapping region in piece, current propeller processing equipment mostly is conventional serial mechanism, plus man-hour be susceptible to flutter, interfere and The phenomenons such as collision, need upset, multiple clamping just to complete the processing of whole screw, and working (machining) efficiency and machining accuracy are low.Such as Working (machining) efficiency, machining accuracy, the rigidity of machine tool and stability can also be improved while where expanding the range of work, is that today's numerical control adds The important problem that the large-scale marine propeller of work is faced.
