Abstract
The utility model discloses a reciprocating motion device which is composed of a motor (1), a shaft connector (2), a hydraulic pressure oil pump (4), an electromagnetic reversing valve (5), and an oil cylinder (7). The oil cylinder (7) is provided with a hollow piston rod (8), an intermediate catheter (6) is arranged in the hollow piston rod (8), oil which is ejected in high pressure by the oil pump (4) is injected into the rodless cavity or the rod cavity of the oil cylinder (7) through the electromagnetic reversing valve (5), the catheter (12), and the intermediate catheter (6), then the hollow piston rod (8) is pushed to extend out or retract inwards, and thereby, the purpose of reciprocating motion is achieved. The utility model has the advantages of simple structure, small size, and easy manufacture, and the utility model can be widely used in various occasions in which a reciprocating motion is needed.
Description
The utility model relates to the hydraulics field, relates generally to a kind of reciprocator.
Disclose a kind of reciprocator in model utility (892173092), the oil cylinder in this device is made up of shell and the oil pipe that enters rod end chamber, and its size is big, and shell is thin yielding, makes difficulty.
The purpose of this utility model provides a kind of reciprocator, and it is simple in structure, easy to manufacture, size is less.
For achieving the above object, the utility model is made up of motor, shaft joint, hydraulic-pressure pump, selector valve, hydraulic jack and fuel tank etc.Its hydraulic jack does not have shell, adopt hollow piston rod, the centre adds a conduit, make hydraulic oil pass through selector valve, conduit enters rod chamber, and rodless cavity links to each other with selector valve one chamber, by the difference action of selector valve, make the fuel-displaced of hydraulic-pressure pump can enter the rod chamber or the rodless cavity of oil cylinder, contract in the oil cylinder fire piston rod or overhanging thereby make by selector valve.
The utility model is simple in structure, and is easy to manufacture, and size is little, can be widely used in the reciprocating occasion of various needs.
Below in conjunction with accompanying drawing the utility model is further described.
Fig. 1 is the utility model structural representation.
Fig. 2 is a kind of embodiment's of the utility model a hydraulic schematic diagram.
Fig. 3 is the another kind of embodiment's of the utility model a hydraulic schematic diagram.
Fig. 4,5 is the utility model two kinds of example structure schematic representation in addition.
Among the figure: 1, motor, 2, shaft joint, 3, fuel tank, 4, hydraulic-pressure pump, 5, solenoid directional control valve, 6, intermediate conductor, 7, oil cylinder, 8, hollow piston rod, 9, front cover, 10, the hole, 11, piston, 12, conduit, 13, rear end cover.
With reference to Fig. 1,2, motor (1) links by shaft joint (2) and hydraulic-pressure pump (4), the difference action of hyperbaric chamber (oil outlet) the energising magnetic selector valve (5) of hydraulic-pressure pump (4) can be injected pressure the rodless cavity or the rod chamber of oil cylinder (7), have the oil return of bar or rodless cavity to get back to fuel tank (3) simultaneously by solenoid directional control valve (5), hollow piston rod (8) promptly stretch out or in the bar that contracts.Oil cylinder (7) is made of rear end cover (13), front cover (9), piston (11), hollow piston rod (8) and intermediate conductor (6), rear end cover has two holes on (13), pass through for entering the conduit (12) of rodless cavity and hollow piston rod (8) and intermediate conductor (6), have hole (10) on the hollow piston rod (8), fluid can be flow to rod chamber or be flowed back to hollow piston rod (8) by hole (10), flows back to fuel tank (3) through intermediate conductor (6), solenoid directional control valve (5).
According to different usage requirements, parallel type (Fig. 4) and orthogonal formula (Fig. 5) can be made in the mounting point of the utility model motor (1) and oil cylinder (7).
The utility model is as adopting two-way oil pump (4), can not use solenoid directional control valve (5), two chambeies of two-way oil pump (4) link to each other with intermediate conductor (6) with conduit (12) respectively, when motor (1) sense of rotation changes, the high pressure of two-way oil pump (4) goes out oil pocket and the low pressure oil back chamber also changes, for example, when motor (1) clockwise direction rotates, two-way oil pump (4) hyperbaric chamber is fuel-displaced to enter rodless cavity by conduit (12), oil return is got back to fuel tank (3) by intermediate conductor (6), piston stretches out, when the motor counterclockwise rotation, two-way oil pump (4) high pressure is fuel-displaced to enter rod chamber by intermediate conductor (6), and oil return is got back to fuel tank (3) by conduit (12), contract in the piston, reach the reciprocating purpose of piston rod thus.(Fig. 3 is the hydraulic schematic diagram of present embodiment)
Claims (3)
1, a kind of electric liquid reciprocator of being made up of motor (1), shaft joint (2), hydraulic-pressure pump (4), solenoid directional control valve (5) and oil cylinder (7) etc. is characterized in that oil cylinder (7) is made of rear end cover (13), front cover (9) and hollow piston rod (8) and intermediate conductor (6).
2, reciprocator according to claim 1 is characterized in that having on the hollow piston rod (8) hole (10).
3, reciprocator according to claim 1 and 2 is characterized in that intermediate conductor (6) places the inner chamber of hollow piston rod (8).
