Course of action that seals the work period of hydraulic full automatic sealing machine tool of the present invention is as follows:
The oil-feed of gland cylinder epicoele promotes the gland descent of piston, and it is descending to drive axostylus axostyle, press box, pressure head, and after the pressure head lower end touched shock absorber end cap, the gland piston stopped descending, had set up this and had sealed the relative datum of work period.Because gland piston rod upper end is equipped with displacement transducer, the gland piston stop when descending displacement transducer also stop descending, thereby also set up the relative displacement datum mark simultaneously in the lathe upper end.The oil-feed of master cylinder epicoele, it is descending to promote master cylinder piston; Hydraulic motor starts, driving belt wheel drive spinning roller main axis rotation, and the roller that the main shaft lower end connects is pressed the also rotation simultaneously of a frame and a pair roller, and under the drive of master cylinder piston and hydraulic motor, roller is rotated the compound roll extrusion of depressing and seals action.Parts such as the handle of displacement transducer parts, displacement adjuster, connecting rod, reflector are installed in the master cylinder piston upper end, can be the reflector that displacement is delivered to the upper end exactly that presses down of roller, to follow master cylinder piston descending when the displacement reflector, during near displacement transducer, displacement transducer detects the signal of reflector reflection, send the returned signal that relative displacement has put in place immediately, instruction gland cylinder and the oil-feed of master cylinder cavity of resorption, gland piston and master cylinder piston are resetted, prepare to carry out the next one and seal the work period.
The adjusting of relative shift is realized by the precision lead screw nut of adjusting rod lower end, rotation regulating handle, the size that can accurately regulate relative shift.
For realizing the accurate braking rotation direction location of high pulling torque axle system, the course of work of whirligig is: after the returned signal that relative displacement puts in place sends, Programmable Logic Controller carries out one section time-delay, Deng being contained in reflector on the adjustment disk when forwarding the position of angular transducer to, angular transducer detects the signal of reflector reflection, immediately magnetic valve is switched to by the position, cut off the motor oil circuit, force roller to press frame to stop the rotation towards the dead ahead.
In order to reach accurate adjustment relative shift, the present invention has taked the technological means of following key:
1) pressure of gland cylinder can be regulated, and makes pressure head can reach very little to the pressure of shock absorber end cap.
2) electric system has adopted high-precision photoelectric sensor, and location action uniformity precision can reach 0.05mm, and electrical equipment control mechanism adopts Programmable Logic Controller to control each magnetic valve, makes each mechanism action reliable, high conformity.
3) mechanical part adopts tight screw thread to constitute governor motion, the degree of regulation of relative shift can reach 0.04mm/ per minute degree, on adjusting rod, be provided with the dial of accurate calibration, be convenient to the user and adjust relative shift accurately, on adjusting rod, also be provided with the guider of precision-fit, make reflector and displacement transducer can keep relative position accurately reliably.
To stop in order reaching in any moment of axle system rotation, can both to make roller press frame towards the dead ahead, the present invention has taked the technological means of following key:
1) the conventional motor transmission rotating mechanism of cancellation is selected the driving force of hydraulic motor as the rotation of axle system for use, and the characteristics of hydraulic motor are when input hydraulic pressure oil, can export the revolving force of high pulling torque, drive the rotation of axle system; Can obtain powerful braking effect immediately when cutting off hydraulic oil, stop the rotation of axle system.
2) axle system revolves that to stop being random, direction is uncertain, in order to reach the purpose of directed rotation, on belt pulley, be equipped with can hue angle the angular displacement adjustment disk, angular transducer detects emitter signal fixing on the adjustment disk, and the input Programmable Logic Controller is through differentiating computing, and the output control signal makes reversal valve cut off the motor oil circuit, powerful brake force overcomes the inertia of axle system, can make roller press frame to be parked in position towards the dead ahead.
3) revolve the stopping time suddenly in axle system, can produce strong wallop in the hydraulic system,, set up buffer loop in order well to absorb hydraulic shock in hydraulic system, buffer loop by check valve and overflow valve are formed can absorb powerful braking impulsive force fully.The oil pressure relief of simultaneously suitable fine setting overflow valve can the fit angle adjustment disk, accurately regulates and revolves the position of stopping; Can finely tune the dynamics that absorbs buffering, improve the feature of hydraulic system.
The major advantage of hydraulic full automatic sealing machine tool of the present invention is the incorporate advanced technology means of application machine electrical equipment hydraulic pressure, successful has reached no matter how many deviations are the damper length overall have in the larger context, can both realize that each seals accurate displacement backhaul of work period, successfully be able to accurately adjust relative shift, successfully reach in any moment of axle system rotation and stop, can both make roller press frame towards the dead ahead.
