For solving the problems of the technologies described above, digital control automatic dry cutting gear-hobbing machine in high speed of the present invention, has lathe bed, big column, post, workbench, hobboing cutter case and knife rest, big column, post and workbench are installed on the lathe bed, the hobboing cutter case is installed on the big column by linear rolling track and ball screw, wherein: between servomotor output shaft in the hobboing cutter case and the hobboing cutter main shaft is the two-stage gear transmission structure, and terminal is the transmission of difference tooth, on casing, hob arbor is locked on the hobboing cutter bracket by dish spring automatic clamping mechanism the hobboing cutter main shaft by roller bearings; Be the transmission of high accuracy helical gear pair between the main shaft of workbench, jackshaft and the servomotor output shaft, the main shaft of workbench adopts precise rolling bearing to support.
Hobboing cutter case main shaft adopts the two-stage gear drive, makes the driving-chain of hobboing cutter main shaft the shortest, thereby improves the rigidity of gear train; Terminal gear in this two-stage travelling gear adopts the difference toothing, the cutting force that changes in the time of can eliminating gear hobbing brings the influence of vibration to transmission, add the hobboing cutter main shaft and adopt the roller bearings structure, realized the requirement of hobboing cutter axis system high rotating speed, anti-cutting vibration, hob arbor adopts the locking of dish spring, has guaranteed the reliable grip of hobboing cutter main shaft when high-speed dry is cut.The workbench main shaft system adopts the helical gear transmission, helical gear axially displaced satisfy dividing gear in transmission simultaneously with the different sideshakes engagements of driving gear, satisfied the requirement of gear-pair backlash so on the one hand, on the other hand, can realize the compensation of backlash, make condition for realizing the high-speed dry incised wound.
As a kind of preference, above-mentioned lathe bed adopts rigidity symmetry and four layers of wall construction, lathe bed is covered with totally-enclosed protective cover, when lathe bed rigidity is greatly improved, chip cleaner can promptly be got rid of hot smear metal from the lathe bed middle part, and prevent that iron filings from splashing, guaranteed the needs of dry type high-speed cutting.Lathe bed is provided with the compressed air chip removal device and the cold oil circulatory system, adopt the compressed air chip removal, cooling iron filings and hobboing cutter, retention gap and logical compressed air between cutting region stainless steel protective cover and lathe bed, the heat that produces is taken away as soon as possible, and the satisfied high-speed dry of gear hobbing lathe that makes of these conditions is cut safety, reliable.
As another preference, adopt roller to add the linear rolling track of damping and preload between above-mentioned lathe bed and the big column, its stable accuracy is reliable, and avoids safeguarding; And adopted bearing and the ball screw of being with preloading, guaranteed the dynamic stiffiness of lathe.Lathe also has workpiece automatic loading and unloading system and automatic workpiece fixture system, automatic loading and unloading system is made up of double manipulator and the flexible feed bin of loop buffer, this system has been the most reliable in the gear cutting machine, state-of-the-art technology, on gear-hobbing machine and gear shapping machine, used quite successfully at present, guaranteed that the efficient of high-speed dry cutting gear-hobbing machine is brought into play fully; The automatic workpiece fixture system guarantees the workpiece reliable grip under the condition that high-speed dry is cut, satisfied the higher and demanding needs of technological ability index of required precision.
The technique effect that the present invention obtains is: compare with general hobbing machine, working (machining) efficiency is 2～3 times of wet type cutting, cost per unit only is 60% of traditional gear hobbing processing, and the splashing and the generation of mist of oil of no cutting fluid in the process do not polluted and endangered environment and people.
