Description
Technical field
The present invention relates to a kind of lathe, especially relating to a kind of lathe for processing screw, belonging to machinery manufacturing technology field.
Background technology
So far, the processing of large-scale marine propeller adopts following several scheme substantially: 1, first each blade of screw and wheel hub are disassembled independent processing, then used by each assembling parts.The screw that this mode processes limits due to structure, and its symmetry and rigidity are all under some influence, and repeatedly install in addition and there is accumulated error, reliability is poorer than Integral-type screw oar.2, adopt the interlocked numerical controlled milling machine of portal-type multi-shaft, screw is fixed on the workbench in the middle of column, overturn reprocessing another side after processing upper surface, finally adopt a small amount of hand finish.This processing method needs multiple clamping just can complete the processing of whole screw, argosy airscrew diameter, weight comparatively its upset of ambassador and clamping all more difficult, and there is resetting error in multiple clamping, affects the accuracy of manufacture of screw; In addition, mostly propeller blade root is curve form, has overlapping region, and in process, the interference of lathe, cutter and screw and collision problem cannot solve always completely.3, the method using abrasive belt grinding machine and manual grinding to combine is to process screw.Grinding is the finishing operation of general process, completes the fine finishining of part, and surface quality is also better.The operation principle of abrasive belt grinding machine relies on the quick rotation in abrasive band to carry out grinding and polishing to workpiece, but due to current abrasive band and grinding characteristic theoretical research and sbrasive belt grinding complex surface machining technology ripe not enough, add the structure restriction of sbrasive belt grinding self, make the grinding of its how applicable monomer blade.Although manual polishing can complete the grinding and buffing of screw entirety, machining accuracy depends on technical merit and the qualification of workman, work under bad environment, and labour intensity is large, and the subjective destabilizing factor by people affects comparatively large, and efficiency is lower.
For large-scale marine propeller upset difficulty and again clamping bring resetting error, the people such as Zhao Hu in the patent No. of application in 2009 be 200910038368.6 people such as " Six-axis five-linkage propeller machining center " patent and Zhang Shengwen etc. adopt screw laterally to place respectively to avoid overturning in " double power head screw dedicated numerical control specialized nc machine tool and processing method " patent that the patent No. of application in 2012 is 201210233126.6 and make machine tool structure compact and use upper and lower two cover unit head system clamped one times just can complete the processing of whole screw, improve working (machining) efficiency and alleviate labour intensity, certain directive function is provided to the design of large-size propeller machining tool.Along with the development of ocean engineering and defending of sovereignty over territorial waters, both at home and abroad the research and development of argosy propeller processing lathe are also being deepened continuously.At present, the great Han precision optical machinery company of Korea S have developed and can process the marine propeller equipment that diameter is 11 meters, and model is HPMC-110, is can process the maximum equipment of airscrew diameter in the world at present.This lathe adopts planer type structure, and Z axis tiltable, is conducive to the processing of screw overlapping region.Simultaneously its shortcoming can not process the upper and lower surface of screw and planer type structure also has impact to the rigidity of machine tool.Domestic, born by Wuhan Heavy Machines Co., Ltd., " the heavy sevenfive axis turning-milling complex processing lathe of screw " that the Central China University of Science and Technology, Zhenjiang Zhongchuan Wartsila Propeller Co., Ltd. research and develop jointly, pass through appraisal of scientific and technological achievements, there is the functions such as seven axle controls, five-axle linkage turning-milling complex processing, on-line measurement, the comprehensive precision milling processing to machining areas such as screw blade face lap, non-overlapped part, blade profile and propeller hub mesopores can be realized, processing diameter reaches 8.5 meters, expansion can reach 12.5 meters, highly reaches 3.3 meters.Its defect is can not simultaneously to the two-way processing in screw two sides, and working (machining) efficiency is not ideal enough.In addition, planer type structure increases construction weight to improve the rigidity of machine tool, makes lathe entirety too clumsy.
In view of various research approaches above, the processing of large-scale marine propeller is adopt cascaded structure formula lathe mostly.The advantage of cascaded structure is that the motion of lathe each axle is separate, and motion control is simple, and Technical comparing is ripe, and working space is large, and flexibility is good.But serial machine tool is open-chain structure, there is cantilever section, not only bears Tensile or Compressive Loading but also bear bending load, in order to improve the rigidity of system, the weight of component must be increased, make its dynamic performance poor, also constrain increasing substantially of feed speed simultaneously.In addition, in serial machine tool, each link deflection and the superposition of junction deflection make the relative motion error between cutter and workpiece be generally the linear superposition of each coordinates of motion, there is accumulated error.But, parallel institution is just in time to serial machine tool beneficial complement, it has high rigidity, high bearing capacity, high speed, low inertia, advantages of simple structure and simple, there is not serial mechanism accumulated error problem, spatial pose fulfillment capability is strong, especially easily realize six-axis linkage, be very suitable for completing complex-curved processing at Aeronautics and Astronautics, automotive field, as blade, impeller, screw etc., representational be NEOS company of Sweden Tricept series parallel machine, successful Application is on the production line of automobile, aircraft.The characteristic that parallel institution shows makes it very be applicable to processed complex curved surface part and working (machining) efficiency is high, good processing stability.It is existing defects also, and as position forecast is complicated, numerical control programming is complicated, and working space is little.
Large-scale marine propeller is typical complex-curved thin wall component, blade root and wheel hub junction comparatively narrow, there is overlapping region in blade, current propeller processing equipment mostly is conventional serial mechanism, add and man-hour the phenomenons such as flutter, interference and collision easily occur, need to overturn, multiple clamping just can complete the processing of whole screw, working (machining) efficiency and machining accuracy low.How can also improve working (machining) efficiency, machining accuracy, the rigidity of machine tool and stability while the expansion range of work, be an important problem faced by today's numerical control machining large marine propeller.
Summary of the invention
The object of the invention is to be to provide a kind of equipment being suitable for machining large marine propeller, clamped one time just can complete the processing of whole screw, avoids resetting error; Use symmetrical machining can improve working (machining) efficiency and reduce the distortion of screw in process; In conjunction with serial parallel mechanism advantage separately, lathe working space can be expanded, the rigidity of machine tool and machining accuracy can be improved again.
