Description
Technical field
The present invention relates to a kind of two-stage double-act-ing hydraulic J-Horner.
Background technology
Hydraulic jack is the executive component that hydraulic energy is converted to linear motion mechanical energy, and it is simple in construction, reliable operation,
With doing reciprocating linear motion, drive gap useless, stable movement.Be widely used in engineering machinery, it is lathe, mining machinery, overweight
The hydraulic drive of Transport Machinery, metallurgical machinery and engineering truck.
Hydraulic jack is broadly divided into：Single-action hydrocylinder, double-act-ing hydraulic J-Horner, assembled hydraulic oil cylinder and swing hydraulic pressure
Oil cylinder.Single-action hydrocylinder may be designed as multistage, and its operation principle is：When pressure fluid force feed enters cylinder barrel, plunger is promoted
Formula piston driving moving component is travelled forward, but other external force or deadweight driving, double-action hydraulic oil must be leaned on when reversely retracting
Cylinder is generally single-stage oil cylinder, and it is made up of (see figure cylinder body 35, piston 36, guide sleeve 37, piston rod 38 and relevant seal etc.
3).The chamber hydraulic oil action space of A, B two can be formed, controls hydraulic oil press-in or the backflow chamber of A, B two to make hydraulic oil by reversal valve
The piston and piston rod of cylinder do reciprocating linear motion.
In hydraulic machinery equipment, while have the reciprocating situation of two executive components a lot, generally, I
Need two one-level double-act-ing hydraulic J-Horners of configuration to complete its function, but if compare in space residing for two executive components
When narrow and small compact, due to being limited by oil cylinder appearance and size, it is difficult to arrange two one-level double-act-ing hydraulic J-Horners.If by two
Individual one-level double-act-ing hydraulic J-Horner is integrated into a kind of two-stage double-act-ing hydraulic J-Horner, with regard to that can solve this problem.
CN202707402U discloses a kind of two-stage double-act-ing hydraulic J-Horner, and one-level inner hole of cylinder not only plays one-level oil cylinder
The effect of cylinder, its inner hole of outer garden also with second piston piston rod serves as the guide rod effect of two-level oil cylinder's piston rod, made
One-level double-act-ing hydraulic J-Horner and two grades of double-act-ing hydraulic J-Horners become one one-levels double-act-ing hydraulic J-Horner and two grades of double croppings
A1, B1 and A2, B2 oil pockets have been independently formed with hydraulic jack, under the control of hydraulic system, when A1, A2 chamber individually or together
When oil-feed when, B1, B2 chamber just can accordingly oil return, conversely, when B1, B2 chamber are individually or during oil-feed simultaneously, A1, A2 chamber also can phases
Answer oil return；A second piston piston rod of two single-stage double-act-ing hydraulic J-Horners that become one can thus be made individually
Or linear reciprocating motion is carried out simultaneously.
The content of the invention
The purpose of the present invention is to be directed to above-mentioned present situation, it is desirable to provide a kind of compact conformation, good reliability；Stable movement,
The two-stage double-act-ing hydraulic J-Horner that executive component can be made concurrently or separately to do reciprocating linear motion in the range of certain space.
The implementation of the object of the invention is that two-stage double-act-ing hydraulic J-Horner, I and II cylinder barrel is separately fixed at cylinder head method
On blue corresponding installation seam；The I and II piston of I and II movement parts is respectively fitted in the endoporus of I and II cylinder barrel,
The cylindrical of I and II piston rod is respectively fitted in one or two grades of guide sleeve endoporus；The cylindrical of I and II guide sleeve is respectively positioned at
On the corresponding endoporus of I and II cylinder barrel, the inner hole of the cylindrical and second piston piston rod of one-level cylinder barrel serves as two-level oil cylinder
The guide rod of piston rod；The flange section of I and II guide sleeve is fixed on I and II cylinder barrel end face, on ring flange；
Cylinder end flange right side, one-level inner hole of cylinder one, the left side of the first stage piston of one-level movement parts, oil pocket A1 oil
Mouth one forms oil pocket A1；The right side of the first stage piston of one-level movement parts and piston rod cylindrical one, one-level inner hole of cylinder three, one
Level guide sleeve left end, oil pocket B1 hydraulic fluid port two forms oil pocket B1；Cylinder end flange right side, secondary cylinder cylinder endoporus four, first-stage cylinder
The hydraulic fluid port three and relevant sealing ring of cylinder cylindrical three, the left side of the second piston of second degree of motion part and oil pocket A2 form oil pocket
A2；The right side of the second piston of second degree of motion part and second piston rod is cylindrical, secondary cylinder cylinder endoporus two, two grades of guide sleeve left sides
End, oil pocket B2 hydraulic fluid port four form oil pocket B2.
The present invention becomes one two one-level double-act-ing hydraulic J-Horners, can complete the work(of two single-stage two-way cylinders
Can, its compact conformation, good reliability；Drive gap useless, stable movement can make executive component simultaneously in the range of certain space
Or individually do reciprocating linear motion.
The present invention is in hydraulic machinery industry, and particularly jig equipment field has the prospect of extensive popularization and application
With good economic benefit.
