The present invention describes
The present invention relates generally to the automatic hobbing operation of the novelty of carrying out on auto gear hobbing machine (gear hobbing machine), and wherein more than one gear workpieces is arranged on the work arbor that designs suitably and form simultaneously.Work arbor is designed such that it effectively can keep multiple gear workpieces and can realize its multiple gear workpieces contributing to wherein perform predefined mechanical function and the motion of hobbing operation simultaneously.While such, many hobbing operations are applicable to the gear of several types, i.e. spur gear and helical gear, crown gear and angular wheel, worm gear, pinion etc.; Wherein flank profil generates on the cylindrical surface of each gear, its simultaneously as virtual cylindrical gear trade union college on work arbor.Once preferably to be installed on the work arbor of the hobboing cutter milling machine (hob millingmachine) that automatic software guides according to the gear workpieces of work arbor and the size of hobboing cutter cutter and the given number of functional characteristic, virtual cylindrical gear workpiece just generates at this place, and the complete surface of cylinder of wherein said virtual cylindrical gear workpiece is subject to the effect of single hobboing cutter cutter.Described hobboing cutter cutter has such size, preferably there is the size of its hobbing cutting flank profil, there is the length of hobboing cutter cutter and there is the diameter that flank profil is cut in hobbing described in it, and it can cut corresponding flank profil with angle in a desired manner on whole gear workpieces simultaneously.While such on described virtual cylindrical gear workpiece, hobbing operation is suitably programmed, to realize contributing to the hobboing cutter cutter of the rotary motion of hobboing cutter cutter at this place etc. and mutual vertical/horizontal motion, the RPM of hobboing cutter cutter at this place, the frequency of work arbor of work arbor.
The frequency performing hobbing action is regulated by a certain software and/or suitable logical program.
In the particularly preferred illustrative example of hobbing operation while on described virtual cylindrical gear workpiece, technique is carried out in mode step by step below:
Step I: mainly prepare the gear blank workpiece for hobbing by forging operation;
Step II: the gear workpieces of given number is arranged on work arbor, is preferably arranged on work arbor in upright position, and generate virtual cylindrical gear workpiece wherein, preferably automatically carry out;
Step II I: preferably in an automated way, the group of the gear workpieces of described given number (the virtual cylindrical gear workpiece as wherein) is made to stand the effect of the functional cylinder hobboing cutter cutter be preferably positioned on horizontal/vertical or angled direction, contribute to carrying out hobbing operation on those gear workpieces, to produce corresponding tooth on the complete surface of cylinder of described virtual cylindrical gear simultaneously;
Step IV: at the same time after the multiple gear workpieces of hobbing, from the gear that work arbor has been removed, and the gear workpieces of identical number of reloading on identical work arbor, preferably automatically carry out.
Because the contact area between virtual gear workpiece and hobboing cutter cutter and time on multiple gear workpieces of current proposition while greatly increase in hobbing operation, therefore probably produce the flue gas of suitable large volume during operation and form quite high heat.
Therefore, importantly, effective module of described flue gas and the heat produced is discharged in application, preferably carries out in dry mode.In using, the zone of action around hobboing cutter cutter provides effective exhaust fan and effective air circulating umbilical.
For here by the preferred exemplary embodiment of the one of the gear workpieces of hobbing, its preferably on the automatic sharp Bucherer hobboing cutter milling machine of dry type (dry automatic Liebherr hob millingmachine) by hobbing, the thickness of the periphery of gear workpieces or length be 12mm and its diameter in the scope of 40mm to 50mm.Importantly, hobboing cutter milling machine selected in this article belongs to identical platform, and this platform is applicable to one by one and the similar gear workpieces of non-concurrently hobbing usually.Therefore, gross thickness or the total length of the cylinder circular surface of the described virtual cylindrical gear workpiece be made up of wherein five single gear workpieces are 60mm.The diameter of described virtual cylindrical gear workpiece is identical with the diameter of whole five the single gear workpieces be wherein arranged on work arbor, namely in the scope of 40mm to 50mm.
If hobbing operation is carried out in a conventional manner on identical automatic dry type gear-hobbing machine, then only have a gear workpieces by by the elapsed time in a hobbing cycle of hobbing, and this time is preferably 75 seconds.But according to the method for the multiple gear workpieces of hobbing while proposed, total time be also preferably 75 seconds at the complete hobbing cycle internal consumption of for producing tooth on the complete surface of cylinder of described virtual cylindrical gear workpiece here comprising five single gear workpieces here.Therefore, the time that hobbing cycle of the gear workpieces that thickness is 12mm consumes only have virtual cylindrical gear workpiece described in hobbing to consume altogether 75 seconds 1/5th, namely 15 seconds.
In addition, in another preferred illustrative example of hobbing operation at the same time, gear workpieces is such, namely there is some lug (lug) on that is arranged in its flat surfaces.Because the surface of gear workpieces is rough and is not suitable for multiple that stack described gear member, and therefore some spacer elements is sandwiched between two gear workpieces, form correct virtual cylindrical gear workpiece.Therefore, the preferred exemplary embodiment of virtual cylindrical gear workpiece is produced as the single real gear workpieces and spacer elements that comprise and alternately arranging, and wherein the number of single gear workpieces is pre-determining.The such virtual cylindrical gear workpiece be made up of multiple gear workpieces and multiple spacer elements compatibly stands as hobbing while proposing in this article operates.
Scope of the present invention
Although describe the present invention with reference to particular implementation, this description is also not intended to explain in limiting sense.To those skilled in the art, after with reference to the description of this invention, the various amendments of open embodiment of the present invention and replacement embodiment will be obvious.Therefore, should expect, such amendment can be made and do not depart from the spirit or scope of the present invention as defined.
