The specific embodiment
For the utility model is become apparent, hereby with a preferred embodiment, and coordinate accompanying drawing to be described in detail below.
The vertical five axle gear hobbing machining tool schematic diagram that Fig. 1 provides for the utility model, described vertical five axle gear hobbing machining tool comprises frame 10, hob head is arranged on frame 10 by column 8, hob head with column 8 for being fixedly connected with, hobboing cutter 2 is housed on hob head, the first servomotor 3 connects hobboing cutter 2, the second servomotors 4 and connects column 8, and whole column partly is arranged in frame 10 1 sides; Carriage 6 is arranged on opposite side on frame 10, and workbench is arranged on carriage 6, for driving workpiece to be processed tooth base 1, around the 3rd servomotor 5 from the axle rotation, is contained in workbench, the 4th servomotor 7 connecting working tables, and the 5th servomotor 9 connects carriage 6.Angle beta ± λ is hobboing cutter 2 established angles, need determine concrete "+" or "-" symbol according to actual processing method.
Tooth base 1 is arranged on workbench, tooth base 1 be installed as vertical mounting means, tooth base 1 axis is vertical with the driving water plane.
The first servomotor 3 drives hobboing cutter 2 around rotating from axle; The second servomotor 4 drives ball screw and drives column 8, and the motion of column 8 drives the hob head motion makes hobboing cutter 2 along tooth base 1 axial feed; The 3rd servomotor 5 driving gear bases 1 are around rotating from axle; The 4th servomotor 7 drives workbench, and tooth base 1 Yan Qi center and hobboing cutter 2 centers of on workbench, installing are changed; The 5th servomotor 9 drives ball screw, and on ball screw, travelling nut and carriage 6 connect into an integral body, thereby drives carriage 6 motions, and workbench is along 1 tangential motion of tooth base.

The vertical five axle gear hobbing machining tool that the utility model provides is mainly for the processing non-circular gear, especially helical teeth non-circular gear, be applicable to process the non-circular gear of median size (maximum utmost point footpath 100～600mm), be particularly useful for five-axle linkage gear hobbing processing non-circular gear method; Helical teeth non-circular gear for small-sized (maximum utmost point footpath 100mm is following) also can adopt five axles or four-axle linked hobbing method to carry out gear hobbing processing on this lathe.
When processing median size non-circular gear or helical teeth non-circular gear, adopt the processing of five-axle linkage gear hobbing processing method on lathe, detailed process can be divided into two steps:
1) hobboing cutter does not have the feed along tooth base axial direction, be that hobboing cutter adds man-hour along tooth base circumference rolling cut, four-axle linked, that is: hobboing cutter around from axle motion, tooth base around from axle motion, hobboing cutter and tooth base centre-to-centre spacing change in displacement, hobboing cutter is along tangential the moving of tooth base circumference, and this cutting movement is topmost cutting movement;
2) when hobboing cutter has along tooth base axial feed, motion state becomes five-axle linkage, that is: hobboing cutter along the moving of tooth base axial direction, hobboing cutter around moving from axle, the tooth base around moving from axle, hobboing cutter and tooth base centre-to-centre spacing change in displacement, hobboing cutter be along tangential the moving of tooth base circumference, because axial feed only just carries out after the cutting of tooth base circumference at hobboing cutter, therefore this cutting hobbing motion is not topmost cutting movement.
When the small-sized non-circular gear of processing or helical teeth non-circular gear, at this moment also can adopt four-axle linked mode gear hobbing processing, its detailed process is divided into again two steps:
1) hobboing cutter does not have the feed along tooth base axial direction, be that hobboing cutter adds man-hour along tooth base circumference rolling cut, the three-shaft linkage gear hobbing, that is: hobboing cutter around from axle motion, tooth base around from axle motion, hobboing cutter and tooth base centre-to-centre spacing change in displacement, this cutting movement is topmost cutting movement;
2) when hobboing cutter has along tooth base axial feed, motion state at this moment adds that hobboing cutter is four-axle linked around becoming around linking from axle motion, hobboing cutter and tooth base centre-to-centre spacing change in displacement from axle motion, tooth base, and this cutting hobbing motion is not topmost cutting movement.
