Description
Technical field
The present invention relates to a kind of numerical control cutting machining tool, be specifically related to the parallel-series principle milling vehicle combined numerically controlled machine that a kind of series connection combines with parallel connection.
Background technology
Traditional lathe is the principle of connecting fully, and its advantage is that working space is big; The machine tool motion algorithm is simple.Shortcoming is that the kinematic error of each adds up; A little less than the cantilever design rigidity; Moving-mass is big, and feed speed can not be too high.The U.S. has at first released six complete principle of parallel lathes (claiming virtual-shaft machine tool or six sufficient parallel machines again) in recent years,, its advantage is that the movement parts quality is little, speed is fast; Specific stiffness is high; Kinematic error does not add up, and precision is high.Shortcoming is that working space is little; Motion algorithm is complicated.Because the principle of connecting fully is on the contrary with the pluses and minuses of the Digit Control Machine Tool of complete principle of parallel; So will connect and the principle of parallel parallel-series principle lathe that combines both advantages be the novel numerical control lathe that has very much practical value, so various countries research and develop unexpectedly mutually.Five parallel-series principle Digit Control Machine Tools (three parallel connections and two series connection) of U.S. exploitation for example; Three machining centers (two parallel connections of Germany A Heng polytechnical university exploitation; A series connection); Four parallel-series principle Digit Control Machine Tools (two parallel connections, two series connection) of Tsing-Hua University's exploitation, six parallel-series principle Digit Control Machine Tool 6PM2 various types of parallel-series principle Digit Control Machine Tools such as (three parallel connections and three series connection) of Xi'an University of Technology's exploitation.
Composite processing machine tool has multiple machining functions, so can workpiece multi-step process even whole operation be focused on a machine tool, makes the process intensification.The installing and locating number of times of workpiece can be reduced, thereby its installing and locating error can be reduced; The frock clamp number of packages of operation can be reduced, thereby the time and the cost of frock can be reduced; Can reduce to change required non-cutting times such as wait, loading and unloading and clamping, improve productivity ratio because of operation; Logistics system is shortened, thereby can significantly reduce the floor space of system of processing.Because the above-mentioned advantage of multi-functional composite processing machine tool; Competitively research and development both at home and abroad, the SLC type numerical control compound lathe (with the turning function is main, has the milling function concurrently) that for example Japanese gloomy smart mechanism work is developed; The Mandelli 800U type horizontal Machining centers of Italy Mandelli company exploitation; Except that the milling function, also have the turning function, be one with the milling be the basis mill the car composite processing machine tool.
General turnning and milling or mill the car composite processing machine tool; Must confirm range by the required maximum of workpiece crowd, the minimum dimension of processing; For example process slewing parts; Minimum dimension is that radius is zero (cutter need move to the centre of gyration), and the full-size radius is Rmax (it is the Rmax place that cutter need move to maximum radius), and then radial stroke must be greater than Rmax.The stroke of lathe is big, and the feed component size that not only needs is big, but also often brings shortcomings such as the increase of lathe weight, reduced stiffness.But generally have only undersized solid part just need carry out from zero continuous processing to outer rim; As far as the large scale slewing parts, all be annular solid generally, though accessory size is big, do not need the continuous processing of O～Rmax.Non-rotating type of part also has similar problem.Therefore the processing of satisfying from the small size to the large-scale part like how as far as possible little stroke is a key technology that using value is arranged very much.
