Described piston-rod lower end is through at the bottom of oil cylinder, and piston rod has axially symmetrical semi-circular groove with the face of slipping at the bottom of oil cylinder, and bottom oil cylinder, also correspondence has semi-circular groove, and the round groove of HBV"liang dui ban" close up after circular trough revolve pin built with preventing.
Described oil cylinder comprises at the bottom of oil cylinder, cylinder wall, low-pressure cavity, hyperbaric chamber, oil cylinder is cylinder wall in one week, cylinder wall upper end is at the bottom of oil cylinder, cylinder wall lower end is by adpting flange connection sliding block, piston is equipped with in oil cylinder inside, and piston upper end connects piston rod, and piston rod is through at the bottom of oil cylinder and frame upper end, piston is low-pressure cavity above oil cylinder is divided into and is hyperbaric chamber below, and low-pressure cavity and hyperbaric chamber side have oil duct junction.
Described driving wheel is connected through retarder by gear, belt pulley or worm screw with actuating motor.
The utility model has the advantages that
1, be applicable to the hydraulic actuator without lateral force, driving wheel and actuating motor Connecting format various, can be gear, belt pulley or worm screw connects after slowing down;
2, piston rod one end is screw pair, by driven by servomotor, has splendid high frequency response, accurately location, synchronization control function;
3, the multiple force combination of driving moment, low-pressure cavity, hyperbaric chamber, can realize the function of the large load of low speed, high speed light loading lotus;
4, under lower-speed state, there is no the creeping of traditional oil cylinder, tremble shake phenomenon;
5, synchronous driving pressurized cylinder array, provides the normal thrust of Large-Area-Uniform, is particularly suitable for large-sized sheet material compressing;
6, the pressurized cylinder bodily form is tiny, can use in groups in pairs, the parameters such as synchronization control time, stroke, pressure, speed, the nominal pressure that concentrated formation is larger, and system cost is far below traditional Large Oil pressing system;
7, pressurized cylinder only fills draining liquid when work is entered, during idle running by screw mandrel drive fast fast under, do not have the large discharge of traditional oil cylinder to fill the overflow and restriction loss of letting out at a high speed, energy-saving effect is remarkable, and oil mass is few, it is little to pollute.
Accompanying drawing explanation
Fig. 1 is schematic diagram of the present utility model.
