Description
Technical field
The utility model is related to a kind of automatic top tight workpiece devices of SERVO CONTROL depth drill oil head, belong to machine tool technology neck
Domain.
Background technology
To solve military project new product（Big bullet）The high efficiency of orthodrome deep hole processes problem, has developed special use for the first time
In the CNC deep-hole drilling ＆ boring machine of military industry field orthodrome deep hole machining, wherein oil head top tight workpiece mechanism is important composition portion
Point.
When using BTA BTA deep hole drillings in deep hole machining, the coolant liquid with pressure squeezes into workpiece by oil head
In machined hole, it is desirable that oil head top tight workpiece, and oil head pivotable parts are driven by workpiece and are rotated.Oil head holds out against work
The pressure of part is different and different with bore diameter.If pressure is too small, the coolant liquid with pressure is most probably from oil head
Splash at sealing between pivotable parts and workpiece.If pressure is excessive, machine power can be excessively consumed, oil head can turn
Sealing ring between dynamic part and workpiece is easily crushed.Previous use is held out against manually or oil cylinder is held out against, and the degree of automation is low, oil
Cylinder holds out against that there are the hidden danger such as unstable.
Invention content
The utility model provides a kind of automatic top tight workpiece device of SERVO CONTROL depth drill oil head, it is ensured that BTA
（Boring and Trepanning Association）The stability of interior chip removal system operation, improve the degree of automation and
Working efficiency.
Technical solution adopted by the utility model to solve its technical problems is：
Oil head shape is cylindrical parts, and install cutter guide sleeve in front aperture is oriented to for cutter, thereafter stomidium
Interior installation drill rod sleeve is used to support drilling rod；The sealing ring top tight workpiece of its front end surface is simultaneously rotated with workpiece, to ensure to arrange in BTA
Consider the sealing of deep hole drilling system to be worth doing.
Oil head is mounted in the big part hole of guiding centre frame.Guiding centre frame can be along Workpiece length on the guide rail of lathe bed
Direction is moved forward or rearward, to drive oil head top tight workpiece or leave workpiece.
The pressure of oil head top tight workpiece according to the pressure of drilling pore size and coolant liquid and flow difference without
Together.The present apparatus can set pressure and automatically control top by program according to bore diameter and the pressure and flow of coolant liquid
Clamp force.
Guiding centre frame drives oil head top tight workpiece or leaves workpiece, and power is by the AC servo in guiding centre frame
Motor drives, and power is reached worm screw by a pair of of gear drive;After worm screw-worm-drive, horizontal drive shaft is converted
For vertical drive shaft, power is reached into gear, is engaged with the rack on lathe bed by gear, to make guiding centre frame drive by
Oily device is moved forward or rearward, and top tight workpiece or leaves workpiece.
When oil head top tight workpiece, by the current feedback of AC servo motor, when current value reaches corresponding pressure
When（Program setting pressure size is corresponding with current value）, system automatically control AC servo motor power-off, make guiding centre
Frame drives oil head to stop increasing pressure；The electricity loss brake of worm shaft left end starts braking, and worm gear-snail automatically simultaneously
Bar machinery retaining plays the role of mechanical, electrical dual holding pressure.
If during BTA BTA deep hole drillings, encounters and forge a knife, block up situations such as considering to be worth doing, be mounted on oil head
Electrolysis point pressure gauge pressure values can increase, when pressure value is increased to setting value, system automatically controls drilling rod feed-disabling, cold
But liquid stops supply, while the electricity loss brake of worm shaft left end cancels braking automatically, AC servo motor obtains electric, guiding centre
Frame drives oil head to move backward automatically, and oil head is made to leave workpiece, and withdrawing checks cutter.
The utility model has the beneficial effects that：The utility model ensures the operation of BTA bta deep hole drilling drilling systems
Stability improves the degree of automation and working efficiency, eliminates oil cylinder and holds out against and unstable there are problems that security risk.

Specific implementation mode
Fig. 1, Fig. 2, a kind of automatic top tight workpiece device of SERVO CONTROL depth drill oil head are referred to, 2 shape of oil head is
Cylindrical parts, the interior installation cutter guide sleeve of front aperture are oriented to for cutter, and installation drill rod sleeve is used to support in stomidium thereafter
Drilling rod；The sealing ring top tight workpiece 1 of its front end surface is simultaneously rotated with workpiece 1, to ensure the close of BTA BTA deep hole drilling systems
Envelope.
Oil head 2 is mounted in the big part hole of guiding centre frame 10.Guiding centre frame 10 can be along work on the guide rail of lathe bed 5
1 length direction of part is moved forward or rearward, to drive 2 top tight workpiece 1 of oil head or leave workpiece 1.
The pressure of 2 top tight workpiece 1 of oil head it is different according to the pressure of drilling pore size and coolant liquid and flow and
It is different.The present apparatus can set pressure and automatically control by program according to bore diameter and the pressure and flow of coolant liquid
