Ring.
The Automatic Control Theory of porous single head different phase difference feed speed is as follows:
High pressure liquid pressure oil enters through oil path block oil inlet 26, through 23a mouthfuls of first set one-way throttle valve 22, solenoid directional control valve,
By 1A confession oil, hydraulic cylinder rod is fed fastly, and through flow rate regulating valve, by 1B mouthfuls of oil returns, (feed speed is unidirectionally saved hydraulic oil by first set
Flow valve, flow rate regulating valve control), complete the stage one；
Through the 4th test point D, at first set electromagnetic switch valve core in position it is self-locking, high pressure liquid pressure oil is through second set of unidirectional section
Valve, a mouthfuls of solenoid directional control valve are flowed, by 2A confession oil, hydraulic cylinder rod is fed at a slow speed, and hydraulic oil is through flow rate regulating valve by 2B mouthfuls of oil returns
(feed speed is controlled by second set of one-way throttle valve, flow rate regulating valve), completes the stage two；
Through third test point C, at second set of electromagnetic switch valve core in position it is self-locking, high pressure liquid pressure oil is unidirectionally saved through first set
Flow valve, a mouthful of solenoid directional control valve, oily by 1A confession, hydraulic cylinder rod is fed fastly, hydraulic oil through flow rate regulating valve by 1B mouthfuls of oil returns, it is complete
At the stage three；
Through the second test point B, at first set electromagnetic switch valve core in position it is self-locking, high pressure liquid pressure oil is through second set of unidirectional section
Flow valve, a mouthful of solenoid directional control valve, oily by 2A confession, hydraulic cylinder rod is fed at a slow speed, hydraulic oil through flow rate regulating valve by 2B mouthfuls of oil returns,
The completion stage four；
Through the first test point A, second set of solenoid directional control valve commutation, high pressure liquid pressure oil is through 2B confession oil, and hydraulic cylinder rod is at full speed
Go up, hydraulic oil gos up to stop, so far completing a working cycles through 2A mouthfuls of oil returns through test point E.
Bore diameter is inputted to system before operation and by drill workpiece material, system can calculate needs to feeding machine with this
The centripetal force that structure applies, and issue and instruct to servo valve valve island, adjustment system pressure is, it can be achieved that control to centripetal force.The control
System can be suitble to the boring requirement of unlike material different pore size.Into the stage four, (it is completely saturating to drilling sword that apex point has just penetrated clamping plate
Before crossing) program carries out linear attenuating to system pressure to the sending instruction of servo valve valve island, and then linearly reduces centripetal force.Prevent
Stage drill bit easy to damage easily causes drilling internal taper phenomenon.
