Description
Technical field
The present invention relates to bevel gear making field, more particularly, to a kind of pendulum rolling pair of vertical knee-type milling machine Special curve bevel gear
Knife system.
Background technology
The processing of spiral bevel gear is typically processed using cutting, and its finishing typically uses roll flute, and roll flute easily occurs
The manufacturing deficiencies such as flank of tooth microfissure, flank of tooth burn.It is that one kind uses cone mould office on workpiece axial end that cold pendulum, which grinds technique,
Portion contacts and rolling of pressurizeing, and makes the shaping method of workpiece continuous modification, and the flank of tooth put after grinding is highly polished, flank of tooth anti-wear performance
It is good.In general, cold pendulum, which grinds technique, is realized in special cold pendulum mill.Because special rotary forging press bed is worth costliness, do not have
When having special pendulum mill bed, by design specialized frock on normal vertical miller, the low of spiral bevel gear can also be realized
Cost pendulum grinding machining.
Cold pendulum grinds theoretical, pendulum stone roller method and puts the common knowledge that is designed as grinding cutter, in pendulum grinding machining, for certain work
Part, pendulum, which grinds tool coordinate system and workpiece coordinate system, specific space geometry position relationship.Pendulum rolles over cutter and workpiece has made
Into afterwards, the two coordinate systems are all the Virtual space coordinate systems for depending on actual parts, are existed between the two coordinate systems
Certain coordinate system translation, the space geometry relation of coordinate system revolution, when pendulum rolles over beginning, therefore, to assure that the two correct space
Geometrical relationship.
When pendulum rolles over spiral bevel gear on normal vertical miller, pendulum rolles over Cutting tool installation manner on milling machine spindle, is processed zero
Part is installed on the index table on milling machine table, according to the existing structure and its technical characterstic of vertical knee-type milling machine, is determined
The space coordinates that pendulum is rolled on cutter are with the locus of part to be processed coordinate system and its geometrical relationship unknown and uncertain,
Related mature technology is had no in existing literature and data, this just becomes restriction pendulum on general-purpose vertical milling machine and rolles over curve tooth cone tooth
The technical bottleneck of wheel.So how on vertical knee-type milling machine it is accurate determine the pendulum for being present in Virtual Space grind tool coordinate system with
The correct spatial relation of workpiece coordinate system, it is that can realize that pendulum rolles over the key of processing curve bevel gear.
