Description
Technical field
The present invention relates to a kind of positioning and clamping device of gear, more particularly to the quick positioning and clamping of major axis type gear roll flute
Device and positioning and clamping method.
Background technology
High-precision axle type gear workpiece when gear teeth molding roll flute is processed, typically using default high accuracy on workpiece
Positioning datum of the top contact positioning on centre bore and lathe as workpiece, the operator of molding gear grinding machine bed first have to pass through
It is top under adjustable on dial gauge centering gear grinding machine working platform so that under lathe, the top centre of gyration and platen returns
Turn in the accuracy rating that center is maintained at same, then lifting workpiece makes that its lower end centre bore is top with lathe tentatively to be completed to connect
Touch positioning, then operate the upper end center hole of the upper top downward workpiece pressing of gear grinding machines, complete upper and lower two centre bore and meanwhile with it is upper
Under it is top contact positioning, realize the Quick self-centering of workpiece, it is ensured that positioning precision of the gear in lathe.
Due to molding gear grinding machine bed and the reasons in structure of workpiece itself, this positioning mode has two in reality processing
Plant defect：First, upper and lower two top molding gear grinding machines are carried, the stroke between which is up and down top is for the height of workpiece to be machined
Degree is conditional, and the workpiece highly more than the upper and lower top range of lathe is cannot be top completing clamping by lathe two
, thus the axle type gear more than certain length roll flute processing cannot be carried out using the method for two top positioning, do not have in addition
The axle type gear workpiece of centre bore cannot more use molding gear grinding machine roll flute；Second, for the impaired workpiece of centre bore, utilize
During two top positioning, the true axis of rotation of workpiece can be caused much to deviate the datum axis of lathe because of the exception of centre bore,
At this moment centre bore is positioned it cannot be guaranteed that the positioning precision of workpiece.
For two above-mentioned point defects, modal solution is by two kinds of interim and less professional auxiliary at present
Overcoming, a kind of be to process the only uniform screwed holes of 4-6 in the end face of workpiece to frock, blending bolt and one it is simple in the middle of
Mold is fixed on workplace vertical on platen, recycles the micro turn of each bolt (using the micro- of threaded connection presence
There is a small amount of displacement in small―gap suture, bolt band part of starting building) by workpiece slowly centering, because the gap randomness being threadedly coupled it is very big, work
Part is easily loosened in processing, while thread mill drilling can destroy workpiece so that finished product is difficult to meet design drawing requirement.It is another
It is, by upper and lower two groups of chucks, workplace vertical to be fixed between the endoporus of two chucks to plant, by adjusting upper and lower scroll chuck by work
Be present up and down totally eight centering adjustable points in part centering, this device, pull one hair and move the whole body when adjusting centering, and centering does not have any rule
Rule can be followed, and constantly can only attempt completing centering by long-time.Using both auxiliary device, operator's clamping centering
Difficulty is greatly increased, and the gear shaft of clamping centering can be just completed using two centre bores positioning more than ten minutes, and now clamping centering is past
Toward needing six, seven hours of cost to complete, production efficiency is significantly reduced, the needs of batch production can not be met at all.
Moreover, due to the less stable of current auxiliary device, also there is workpiece positioning precision in process and gradually lose
Lose even workpiece and slide equivalent risk, it is easy to cause emery wheel knife, workpiece to scrap even workpiece landing and cause lathe and operation
The injury of personnel, Safety Risk in Production are very big.
Therefore invention one kind can be suitable for all axle type gears includes overlength size axle body, centre bore damage and non-stop layer hole etc.
The quick positioning and clamping device of axle type gear roll flute is extremely necessary.
