The present invention carries out innovative design to the structure of patented pressurized strut built-in machines lock (" a kind of claw lock device the being built in pressurized strut piston " patent No.: ZL2010202022549), keeping on traditional pressurized strut built-in machines lock construction and the constant basis of function, adding the automatic detection function of mechanical lock lock state, relative position function between target and inductive position sensor can adjusted arbitrarily.
Working principle of the present invention is:
Rod chamber enters high pressure oil (or outer carrying pushes main piston rod), and pressure oil (or carrying outward) promotion main piston lever lock opening device moves right and is locked into into lock opening device to claw, starts to lock.When the dead bolt of claw lock enters locked groove, floating piston is under the elastic force effect of the first spring, move right, lock supporting block on the little axle of floating piston ladder also starts to insert claw lock endoporus thereupon, the right side of the little axle of floating piston ladder touches and extrudes guiding element simultaneously, makes guiding element start to move right and extrudes the second spring.Stir while guiding element moves right finger around the shaft axis rotate, thus make target, rotating shaft, finger Coupled motion part around the shaft axis rotate counterclockwise, the induction target surface of target is gradually near inductive position sensor.When the right side of floating piston ladder macro-axis touch claw lock end face and stop motion time, lock supporting block on the little axle of floating piston ladder now also inserts claw lock endoporus completely, mechanical lock is in the lock state, guiding element also stops moving right and extrusion spring, target, rotating shaft, finger Coupled motion part also stop axis around the shaft to rotate counterclockwise, and now the induction target surface of target just in time enters between the induction zone of inductive position sensor.Inductive position sensor, once induction detects target, sends signal to main frame master control system immediately, shows that now mechanical lock has been in lock state (as Fig. 2).
Rodless cavity enters high pressure oil, and pressure oil promotes main piston lever lock opening device to left movement, carries out unlocking action.Now the little axle of the ladder of floating piston no longer extrudes guiding element, also be moved to the left under the second spring force effect of guiding element between itself and cylinder cap, and stir finger axis rotation around the shaft, thus make target, rotating shaft, finger Coupled motion part around the shaft axis both clockwise to rotate, the induction target surface of target exits between induction zone away from inductive position sensor gradually.Inductive position sensor induction can't detect target, sends signal to main frame master control system immediately, shows that now mechanical lock is not at lock state.When guide contacts is locked to claw, stop to left movement (as Fig. 3).
Because inductive position sensor induction precision is very high, distance of reaction only has 0 ~ 1.8mm, therefore only under the complete lock state of mechanical lock, target is coordinated and to be arranged in rotating shaft and to adjust the distance of reaction of target sensitive surface and inductive position sensor, then with boring swollen screw, target is fixedly connected in rotating shaft; During the inner circle taper hole of the cone axis of boring swollen screw by target installation shaft, produce the swollen extruding of cone, target installation shaft is made to produce resiliently deformable, target installation shaft cylindrical becomes large, extruding rotating shaft mounting hole, make it assemble positive pressure to strengthen, and then its frictional force is increased, thus firmly also accurately could fix the position of target.
Present invention employs structure assembly, Autonomous test, bore swollen extrusion technique, in maintenance conventional internal mechanical lock pressurized strut structure, on function and the constant basis of working principle, innovative design is carried out to structure, achieve the automatic of pressurized strut built-in machines lock lock state, directly, reliable detection, and the relative position function that can adjust arbitrarily between target and inductive position sensor, and the testing signal of locking easily feeds back to main frame master control system, numeral can be realized preferably with the master control system of main frame to dock, manipulation is simple, achieve main frame master control system directly to monitor lock state, not only eliminate the potential safety hazard of equipment, meet Technology for Modern Equipment to function Autonomous test and the development trend improving Security needs, and it is simple and compact for structure, rationally, be easy to manufacture and safeguard.
