Traditional herringbone bear processing technology, normally by first for gear blank clamping on lathe, turning goes out the cylindrical of herringbone bear, endoporus and end face, and then clamping is on special double helical gear milling machine, mills out herringbone bear teeth groove.This traditional herringbone bear processing method, need turning and the Milling Process that just can be completed herringbone bear by lathe, double helical tooth tooth milling machine two lathes, due to needs secondary clamping, there is secondary clamping error, have impact on Gear Processing precision, and gear transhipment and secondary installing need to consume a large amount of time, cause herringbone bear to process non-cutting time too much, efficiency is very low.Therefore, the equipment that traditional herringbone bear processing needs is many, and occupied ground is large, manpower is many, the time of consumption is many, and secondary clamping brings again clamping error.Be exactly generally speaking, cost be high, efficiency is low, low precision.
Summary of the invention
In order to overcome, the cost that traditional herringbone bear processing technology causes is high, efficiency is low, the problem of low precision, the present invention designs a kind of high-accuracy high-efficiency herringbone bear machining tool, the Milling Function of the turning function of smooth turning lathe and high-accuracy herringbone gear tooth milling machine is combined on a machine tool, and turning and the public high-precision rotary working-table of milling, thus realize on a machine tool, complete herringbone bear turning and Milling Process.
Technical solution of the present invention: a kind of high-accuracy high-efficiency herringbone bear machining tool, comprise main lathe bed, the upper surface left part of described main lathe bed is provided with the mill teeth column along X-axis side-to-side movement, the right front of described main lathe bed is provided with around the pivotal turning of C axle and the public workbench of milling, and the right back of described main lathe bed is fixed with vertical lathe body; The inner face of described mill teeth column is provided with the milling slide moved up and down along Z axis, and on described milling slide, level is provided with around the pivotal mill teeth electro spindle of S axle, by C axle, X-axis, Z axis three axle moving interpolation, is completed the milling of herringbone bear by S axle; The inner face of described vertical lathe body is provided with the vertical stay moved left and right along U axle, described vertical stay is provided with the vertical tool holder moved up and down along W axle, turned round around C axle on the table by workpiece, vertical stay is along the feed of U Axial and radial, vertical tool holder, along the axial feed of W axle, is completed the turning of excircle of workpiece, endoporus and end face by the lathe tool being fixed on vertical tool holder lower end.
Described mill teeth column is arranged on the top of main lathe bed by the first line slideway, the first ball-screw; Described milling slide is arranged on the inner face of mill teeth column by the second line slideway, the second ball-screw; Described vertical stay is arranged on the inner face of vertical lathe body by the 3rd line slideway, the 3rd ball-screw, and described vertical tool holder is arranged on vertical stay by the 4th line slideway, the 4th ball-screw.
The advantage that the present invention compared with prior art has and effect:
1, a machine tool can work as two lathes uses.High accuracy turning and high-accuracy herringbone gear Milling Function combined machine tool, instead of original smooth turning lathe and high accuracy milling machine, decreases lathe floor space, operating personnel and lathe use cost etc.
2, improve the machining accuracy of herringbone bear.Clamped one time completes turning, the Milling Process of herringbone bear, avoids the error that secondary clamping brings, and improves the accuracy of manufacture of herringbone bear machining accuracy grade and gear and center positioning hole.
3, improve herringbone bear working (machining) efficiency.Complete processing by the disposable clamping of a machine tool, eliminate the non-cutting times such as dismounting, transhipment, secondary clamping, calibration, greatly improve the working (machining) efficiency of herringbone bear.
4, Machine Manufacture cost has been saved.Two high accuracy machining tools are combined into a machine tool, have saved the machine tool component such as a set of digital control system, a high-precision rotary working-table, have greatly reduced Machine Manufacture cost.
