Description
Technical field
The present invention relates to the machine tool accessories field in metal cutting field, specifically a kind of worm screw turnning and milling composite main shaft.
Background technology
In the prior art, it is typically all that car and milling separate that the turnning and milling of high rigidity is compound, is like worm screw processing.It is to use first
Lathe processes worm screw embryo, then processes worm screw with cyclone milling machine, and so cutting rigidity is reliably guaranteed, also there is a kind of use
For electro spindle as the mode of axis servomotor, and spindle power is bigger, there is enough radial-thrust forces, could complete turnning and milling one zero
Part.
The content of the invention
The present invention is in order to solve problem of the prior art, there is provided a kind of worm screw turnning and milling composite main shaft, is fed automatically in long rod
Under conditions of material, disposable clamping turning, the technology machine annex of milling worm screw shaping are completed, improves the alignment of worm screw and several
What precision.
The invention provides a kind of worm screw turnning and milling composite main shaft, including main shaft, front-end of spindle to be connected with by elastic base
Chuck, middle-end are connected with primary shaft belt pulley, and rear end is connected with servo deceleration device.Forked plectrum wheel and fork are installed on described main shaft,
Primary shaft belt pulley is realized with main shaft by the key embryo on forked plectrum wheel slides mating；Described servo deceleration device includes what is be connected with main shaft
Housing, is fixed with worm screw and speed-down servo motor on housing, and described worm screw is connected with worm gear, and it is real that worm gear with main shaft passes through key embryo
Now slide mating；Forked plectrum wheel is connected with fork motion cylinder, and the motion of fork motion cylinder control forked plectrum wheel is so as to controlling main shaft
The turbine that belt wheel enters in the work or control servo deceleration device of driving carries out the work of milling.
The body of work of forked plectrum wheel is distribution car also milling, that is, it can allow primary shaft belt pulley to enter the work of driving still to allow
Turbine in servo deceleration device carries out the work of milling.During distribution shift fork motion cylinder by system command carry out push-and-pull forked plectrum wheel to
A left side moves right.Every time after instruction, after shift fork motion cylinder promotes, by middle level controller by shifting fork bar in shift fork moving gas
After cylinder is closed, forked plectrum wheel middle position is voluntarily returned to, is not directly contacted with it, it is ensured that shift fork is contactless with forked plectrum wheel, rotates noiseless.
When a bar is inserted into front end from the rear end rotary oil cylinder of spindle main body, rotated through spring holder seat by chuck after
Under the promotion of oil cylinder, clamp shift fork motion cylinder and pull to the right, shift fork promotes fork wheel its key is acted on main shaft, then shift fork
Motion cylinder automatic leakage falls source of the gas, and shift fork departs from forked plectrum wheel under the promotion of middle level controller and arrives middle position, make primary shaft belt pulley height
Do not interfere during speed rotation.Conversely, after the completion of turning, scroll bar embryo material shaping, shift fork motion cylinder pushes left end to, and shift fork drives
In the worm gear that key is promoted servo deceleration device by forked plectrum wheel to right-hand member, its function is set to push the side of milling to, when speed-down servo motor belt motor
Dynamic worm screw rotation, then turbine low speed rotation is driven, because forked plectrum wheel and turbine are connected, and depart from main shaft band opinion, so main
The main shaft of axle main body is just controlled by servo deceleration device.Firm power supply is provided to milling after decelerator rotates at a slow speed, effectively
Cut, it would be desirable to turbine pay.After milling is complete, power is returned to primary shaft belt pulley again, turning is carried out and cuts off bar, one
Individual complete turbine just machines.
Beneficial effect of the present invention is：
Solves the bottleneck that the processing of turnning and milling compound worm screw is unable to unitary rigid cutting from principle.This invention can also use other more
The processing of side turnning and milling part, can not be compound so as to solve the problems, such as low side processing, also solves main high-end turnning and milling composite band
The problem of high cost main shaft come.Simple mechanical engagement, thoroughly solve asking for rigidity processing Compound Machining low cost processing
Topic, thus the present invention creative income be it is considerable, it is revolutionary.
Brief description of the drawings
Fig. 1 is front view of the present invention.
Fig. 2 is A-A sectional views in Fig. 1.
Embodiment
The invention will be further described below in conjunction with the accompanying drawings.
Structure of the present invention and its sectional view are respectively as depicted in figs. 1 and 2, including main shaft 1, the front end of main shaft 1 pass through elastic base
Seat 2 is connected with chuck 3, and middle-end is connected with primary shaft belt pulley 5, and rear end is connected with servo deceleration device 4.It is provided with described main shaft 1
Forked plectrum wheel 6 and fork 9, primary shaft belt pulley 5 is realized with main shaft 1 by the key embryo on forked plectrum wheel 6 slides mating；Described servo deceleration
Device 4 includes the housing being connected with main shaft 1, is fixed with worm screw 12 and speed-down servo motor 11 on housing, described worm screw 12 connects
There is worm gear 13, worm gear 13 is realized with main shaft 1 by key embryo slides mating；Forked plectrum wheel 6 is connected with fork motion cylinder 8, fork fortune
