Description
Technical field:
The utility model relates to a kind of complex liquid compressing cylinder.Be mainly used in the rapid system of hydraulic machinery.
Background technique:
Hydraulic jack is in the hydraulic pressure installation hydraulic pressure can be changed into mechanical energy, carries out straight reciprocating motion or swings reciprocating executive component.Along with the development of present hydraulics, because that hydraulic equipment has power is big, easily carry out overload protection, advantage such as volume is little adopts hydraulic equipment to replace shock processing actions such as original machinery is finished punching press, cut, stretching to become possibility.Present hydraulic system adopts the speedup cylinder to obtain speedup except that adopting the speedup oil circuit to obtain the high speed motion substantially.The speedup oil cylinder that uses removes and adopts the peripheral hardware auxiliary cylinders to finish speedup at present, establishes auxiliary cylinders in also adopting and finishes the speedup purpose.It is too big to adopt the peripheral hardware auxiliary cylinders mainly to exist volume, and structure burden can't satisfy the shortcomings such as requirement of device miniaturization; In establish auxiliary cylinders mainly exist difficulty of processing big, make shortcomings such as precision height and cost of production height.
Summary of the invention:
The purpose of this utility model is to overcome above-mentioned deficiency, and the complex liquid compressing cylinder that a kind of volume is little, fabrication and processing convenient, cost of production is low is provided.
The purpose of this utility model is achieved in that a kind of complex liquid compressing cylinder, and it comprises preceding cylinder component, back cylinder component and front and back oil cylinder piston bar coupling assembly.
Cylinder component comprises preceding cylinder block, preceding oil cylinder piston and preceding oil cylinder piston bar before above-mentioned, and in the cylinder block, preceding oil cylinder piston rod rear end was inserted in the preceding oil cylinder piston before preceding oil cylinder piston placed; Back cylinder component comprises back cylinder block, back oil cylinder piston and back oil cylinder piston bar, back cylinder block is connected in preceding cylinder block rear end, back oil cylinder piston places in the cylinder block of back, back oil cylinder piston rod rear end is inserted in the oil cylinder piston of back, front end places in the preceding cylinder block, and links to each other with preceding oil cylinder piston bar by front and back oil cylinder piston bar coupling assembly.
Working principle:
1, forward motion
Hydraulic oil from the back cylinder after hydraulic fluid port 2 enter the back cylinder back cavity, preceding cylinder back cavity is mended into hydraulic oil from fuel tank, back cylinder piston promotes the back cylinder piston rod, preceding cylinder piston rod low pressure is descending fast, reach predetermined pressure in back cylinder back cavity hydraulic oil, hydraulic oil behind the cylinder of back behind the hydraulic fluid port, ante-chamber hydraulic fluid port enter the back cavity of back cylinder and preceding cylinder respectively, oil hydraulic cylinder high pressure worker speed is descending.
2, backhaul action
During backhaul, hydraulic oil only enters the ante-chamber of back cylinder from the preceding hydraulic fluid port of back cylinder, and the hydraulic oil of back cylinder and preceding cylinder back cavity falls fuel tank after rise, and back oil cylinder backhaul simultaneously, leans on the piston rod of back oil cylinder that the piston rod of preceding cylinder is retracted journey.
Compare with existing hydraulic jack, because back of the present utility model oil cylinder is the single-piston rod two-way cylinder, preceding cylinder is a plunger cylinder, and both are compound to have the advantage that volume is little, fabrication and processing convenient, cost of production is low.
