Description
Technical field
The present invention relates to gear machine technical field, particularly relate to numerical control worm gear-grinding machine bed extension bistrique and
The method adding work gear.
Background technology
Numerical control worm gear-grinding machine is straight for high speed, accurately grinding cylinder, helical gear, its objective is profile shifted gear heat
Deformation after process, improves tooth accuracy and fineness, reaches stable drive, reduce noise and propose high-precision requirement.But by
Process principle in it is determined as keeping the linear velocity of emery wheel, it is necessary to use the emery wheel of major diameter.
Existing numerical control worm gear-grinding machine grinding wheel diameter is typically no less than 200mm.
Small diameter gear processing at present, the particularly motor input gear axle of electric automobile gear-box, owing to its structure limits
System, in order to make emery wheel not interfere the bearing positioning boss of workpiece gear, takes turns with emery wheel roll flute, and its grinding wheel diameter is generally no greater than
50mm, this cannot meet Production requirement on the movable numerically-controlled gear grinding machine with worm grinding wheel of work on hand platform.
Summary of the invention
Problem to be solved by this invention is to overcome the deficiencies in the prior art, it is provided that a kind of numerical control worm gear-grinding machine bed
Extension bistrique.
For solving the problems referred to above, the technical solution used in the present invention is:
Numerical control worm gear-grinding machine bed extension bistrique, including grinding head body, grinding head body is arranged on the emery wheel master of lathe by nut
On axle, grinding head body side is provided with electro spindle, and little emery wheel is arranged on electro spindle lower end.
The method of numerical control worm gear-grinding machine bed extension bistrique processing small diameter gear, including procedure below:
Rotate grinding wheel spindle, make little emery wheel center be parked at emery wheel.Emery wheel on the wheel dressing mechanism of lathe exists
High-speed rotation under the driving of finishing motor, little emery wheel is high-speed rotation under the driving of electro spindle, and meanwhile, grinding head body is by lathe
X-axis, Y-axis two axle do interpolation linkage, and little crushing goes out theoretical profile of tooth.
After little crushing completes, lathe rotates grinding wheel spindle, makes little emery wheel center be parked at workpiece gear.By little emery wheel
Center and workpiece gear center alignment, utilize machine Z-axis feed motion, workpiece gear carried out grinding, enter by lathe X-axis
The little emery wheel feed feed motion of row.When, after one teeth groove of processing, little emery wheel exits, and workpiece gear, under lathe C axle drives, is carried out
Divide tooth motion, next one teeth groove is directed at little emery wheel center, also according to above step, is processed second teeth groove, with this
Back and forth, whole Gear Processing is completed.
The present invention provide numerical control worm gear-grinding machine bed extension bistrique, utilize lathe primary characteristic will extension bistrique by
Crushing position is fixed, and utilizes the original wheel dressing mechanism of lathe, little emery wheel is carried out profile modification；The least emery wheel is adopted
By monodentate form grinding method, workpiece is carried out grinding, after processing a tooth, Machinetool workpiece axle automatic indexing, then enter
Row next tooth processing, and so forth, until machining.
The numerical control worm gear-grinding machine bed that the present invention provides extends bistrique and the method adding work gear thereof, is particularly well-suited to
The Gear Processing of minor diameter, it is only necessary to lathe is transformed a little, can reach the specific function of small-diameter grinding wheel grinding worm, this expansion
Exhibition grinding wheel head structure is compact, installs simple, automaticity and efficiency is high, the highest economy.
Use current existing machine tool, on the premise of investment seldom, currently available technology can be completed and do not reach
Processing method, filled up China's technological gap on existing.The information that we grasp the most at present, external same category of device
Do not have this type of grinding head dedicated yet.
Accompanying drawing explanation
Fig. 1 is the structural representation of the present invention；
Fig. 2 is the operating diagram of the present invention.
Detailed description of the invention
Below in conjunction with the accompanying drawings the present invention is described further:
As it is shown in figure 1, numerical control worm gear-grinding machine bed extension bistrique, including grinding head body 1, grinding head body 1 is arranged on by nut 3
On the grinding wheel spindle 2 of lathe, grinding head body 1 side is provided with electro spindle 4, and little emery wheel 5 is arranged on electro spindle 4 lower end.
The method of numerical control worm gear-grinding machine bed extension bistrique processing small diameter gear, including procedure below:
As it is shown in figure 1, rotate grinding wheel spindle 2, little emery wheel 5 center is made to be parked in the horizontal left side.On the wheel dressing mechanism 7 of lathe
Emery wheel 6 is high-speed rotation under the driving of finishing motor, little emery wheel 5 high-speed rotation under the driving of electro spindle 4, meanwhile, and mill
Head body 1 does interpolation by the X-axis of lathe, Y-axis two axle and links, and little crushing goes out theoretical profile of tooth.
As in figure 2 it is shown, after little emery wheel 5 has been repaired, lathe rotates grinding wheel spindle 2, little emery wheel 5 center is made to be parked in level right
Face.By little emery wheel 5 center and workpiece gear 8 center alignment, utilize machine Z-axis feed motion, workpiece gear 8 is carried out grinding and adds
Work, carries out little emery wheel 5 feed feed motion by lathe X-axis.When, after one teeth groove of processing, little emery wheel 5 exits, and workpiece gear 8 exists
Under lathe C axle drives, carry out a point tooth motion, next one teeth groove is directed at little emery wheel 5 center, also according to above step, carries out
Process second teeth groove, reciprocal with this, whole Gear Processing is completed.
The gear shaft that gear tooth portions is close with bearing boss can be processed, reduce the transmission volume of gear-box, particularly solve
Determine the grinding difficult problem of current power automobile gear deceleration case first order gear shaft.
The above, be only presently preferred embodiments of the present invention, is not the restriction that the present invention makees other form.Appoint
What those skilled in the art changed possibly also with the technology contents of the disclosure above or be modified as equivalent variations etc.
Effect embodiment.But every without departing from technical solution of the present invention content, structure and operation principle according to the present invention are to above real
Execute any simple modification, equivalent variations and remodeling that example is made, still fall within the protection domain of technical solution of the present invention.
