Abstract
The utility model relates to an oil pressure cylinder controlling device which solves the problem that transmission is conducted by a motor instead of an oil pump. A piston of which one end is provided with a combined section is arranged in a sealed cylindrical oil storage cylinder. One end of a drive rod is provided with a joint which is combined and connected with the combined section of the piston, and the other end of the drive rod extends out the oil storage cylinder which can make telescopic action. A female screw thread hole in which a screw rod is engaged is arranged in the drive rod. The back end of the screw rod is provided with a trepanning slot in which a speed reduction force output shaft of a normal and reverse rotation motor is sheathed. In addition, both ends of the oil storage cylinder, which are divided by the piston, are respectively provided with an oil transferring hole on which an oil transferring pipeline is respectively arranged. The oil transferring pipelines are correspondingly connected with the oil outlet hole of the oil pressure cylinder.
Description
The utility model relates to the oil hydraulic cylinder Effector, especially refers to a kind of motion control device of the oil hydraulic cylinder without oil pressure pump.
The existing power oil supply system that constitutes with oil pressure pump and oil storage tank generally is to control its action with oil pressure, and not only volume is big, and oil pressure pump cost height, special facility for single oil hydraulic cylinder operation are as oil pressure pincers, oil pressure lathe, oil pressure edge cutter etc., the area that takes up room is many, uses very uneconomical.
The purpose of this utility model provides a kind of oil hydraulic cylinder motion control device without oil pressure pump.
The purpose of this utility model is achieved in that the oil hydraulic cylinder motion control device of exempting from oil pressure pump, comprise oil storage cylinder, piston, driveshaft, screw rod, oil hydraulic cylinder and motor, it is characterized in that: in the airtight cylindrical shape oil storage cylinder piston is set, this piston one end is provided with a combination section; The combination section combination of the one end setting of one driveshaft, joint and piston is joined, and the other end extends and allows to do outside the oil storage cylinder of expanding-contracting action, and be provided with female spiral hole in the driveshaft, engagement one screw rod in this female spiral hole, this spiro rod rear end is provided with a cover hole slot, the deceleration force-output shaft of socket one clockwise and anticlockwise motor in this cover hole slot; Oil storage cylinder is respectively established an oil transportation hole respectively by the two ends of piston separation in addition, and this oil transportation hole is provided with the corresponding transport pipe that is connected with the turnover oilhole of oil hydraulic cylinder.
Last art design, when the positive and negative running of motor, can be by the force-output shaft drive screw, screw rod drives driveshaft, driveshaft drives piston front and back displacement in oil storage cylinder, make the fluid in the oil storage cylinder produce pressure, obtain the effect that the oil hydraulic cylinder action is controlled as expanding-contracting action by the piston rod that transport pipe promotes in the oil hydraulic cylinder.
Below by drawings and Examples the utility model is described further again:
Fig. 1, the utility model structure decomposing schematic representation;
Fig. 2, the utility model structure cross-sectional schematic;
Fig. 3, the utility model oil hydraulic cylinder process schematic representation;
Fig. 4, the utility model oil hydraulic cylinder backhaul schematic representation;
Fig. 5, another embodiment's schematic representation of the utility model driveshaft;
The local enlarged diagram of Fig. 6, Fig. 5;
As shown in Figure 1, 2: piston 11 is arranged in the oil storage cylinder 10, and piston 11 1 ends are established combination section 110, have sphere to connect hole 111 in the combination section 110; Driveshaft 20 1 ends are provided with spherical and connect the spherical joint 21 that matches in hole 111, and the other end extends outside the oil storage cylinder 10, allows to do expanding-contracting action, and is provided with female spiral hole 22 within it.
Consult Fig. 3,4, extend driveshaft 20 ends outside the oil storage cylinder 10, have limit flap 23, offer a plurality of axis holes 231 of wearing on this limit flap 23; One supports the axis holes 231 of wearing of seat 30 corresponding limit flaps 23 to offer perforation 32, and each is bored a hole to wear in 32 and supports axostylus axostyle 33, to support 20 rotations of restriction driveshaft, makes screw rod 40 positive and negative rotations, and effectively transmission driveshaft 20 is made expanding-contracting action.
Shown in Fig. 5,6, driveshaft 20 ends, the joint that stretches is by the toothrow bar 24 of supporting that seat 30A supports, and force-output shaft 51 is provided with the gear 52 that is meshed with toothrow bar 24.Like this, gear 52 drives toothrow bar 24, controlling and driving bar 20 expanding-contracting actions in view of the above.
Consult Fig. 1,2, screw rod 40 is behind the axis hole 31 of supporting seat 30, with the female spiral hole 22 in the driveshaft 20.Engagement, its rear end is provided with a belled part 41,41 the inners, belled part offer a cover hole slot 410, after force-output shaft 51 is connected, drive screw 40 is transmission driveshaft 20 again, and along support axostylus axostyle 33, thereby pulling piston 11 is at oil storage cylinder 10 intrinsic displacements, through the oil transportation hole 12,13, the oil of band pressure enters oil hydraulic cylinder 60 through the turnover oilhole 61,62 of oil hydraulic cylinder 60 in the nationality transport pipe.Control piston bar 63 expanding-contracting actions this shows, the clockwise and anticlockwise of mat motor 50 just can obtain oil hydraulic cylinder action, i.e. the action of contracting of piston rods 63 in the oil hydraulic cylinder 60 to operate facility, is processed.
