Abstract
This invention shows an auto reciprocate hydrocylinder. It includes cylinder rod (1), rider (3), plunger (9), rider ring (10), cylinder (13), sealing element and the structure which makes the cylinder auto reciprocate. The structure is: the pull rod (8) which is in the cylinder rod(1), the change valve(16) which is connected with cylinder(13) and the spring installation which is located on the left of plunger(9); The O tow-position four-port valve, which is connected with the left of the pull rod, is in the change valve(16). This cylinder rod can auto reciprocate under the hydraulic liquid without external control. The structure of this invention is simple, convenient. It is a long length of stroke and a basic standard construction element.
Description
Technical field
The present invention relates to become with active bent axle motion the equipment of the occasion that comes and goes straight-line crankshaft ﹠ connecting, particularly relate to a kind ofly, directly realize the hydraulic jack of straight reciprocating motion by hydraulic power.
Background technique
It is reported, make oil cylinder reciprocal, having only commutates by related electric control method control electromagnetic valve realizes, in case malfunctioning (malfunctioning as position limit switch, solenoid valve burns etc.) will cause the accident, influence is produced.
Summary of the invention
Technical problem to be solved by this invention is: a kind of automatic reciprocating hydraulic oil cylinder is provided, and this oil cylinder piston does not need any external control, directly realizes straight reciprocating motion under the effect of hydraulic oil, and simple in structure, and reliable in action is easy to use.
The technological scheme that the present invention solves its technical problem employing is: comprise piston rod, guide sleeve, piston, guide ring, cylinder body and Sealing, also comprise and realize the automatic reciprocating mechanism of oil cylinder.The structure that realizes the mechanism that oil cylinder is automatic reciprocating is: be positioned at the pull bar of piston rod cavity, the selector valve that links to each other with the cylinder body left part, and the spring assembly that is installed in the piston left end; Selector valve is two position four-way valves of " O " type location, the left end of this valve cylinder lever connecting rod, and selector valve is connected with the spring assembly left end, and the spring assembly right-hand member is connected with the pull bar left end.
The present invention compares with legacy equipment, has following main effect:
One. have the function of automatic reciprocating motion: broken the general layout that traditional to-and-fro motion relies on crankshaft-link rod just can be achieved fully, changed reciprocating kinetic characteristic, can realize the to-and-fro motion of long distance.
They are two years old. and simple in structure: as to have save external control component, for example do not needed parts such as position limit switch, solenoid valve.
They are three years old. reliable in action, and easy to use.
They are four years old. are widely used: be a kind of basic component, can be widely used in the various occasions that mechanical industry need be become straight reciprocating motion by the active rotation motion, take out (adopting) oily machine etc. as shaping machine, piston high-density pump, oil field.Be a kind of mechanical industry standard member, it can solve a lot of mechanical components that must become passive straight reciprocating motion originally with the active revolution that crankshaft-link rod could be realized.

Embodiment
The invention will be further described below in conjunction with embodiment and accompanying drawing.
Structure of the present invention is as shown in Figure 1: comprise that piston rod 1, dust ring 2, guide sleeve 3, axle with seal ring 4, this special circle 5, " O " RunddichtringO 6, piston 9, guide ring 10, cylinder body 13, also comprise and realize the automatic reciprocating mechanism of oil cylinder.The structure of described mechanism is: be positioned at the pull bar 8 of piston rod 1 inner chamber, the selector valve 16 that links to each other with bolt nut assembly 15 by fixing pin 14 with cylinder body 13 left parts, and the spring assembly that is installed in piston 9 left ends; Selector valve 16 is two position four-way valves of " O " type location, and this valve is connected with the left end of pull bar 8.
Described spring assembly can be made up of spring case 11 and the spring 12 that is contained in its box, this spring 12 and the pull bar 8 full existing automatic reciprocating key devices of reciprocating oil cylinder.
The right-hand member of above-mentioned pull bar 8 is equipped with regulates nut 7, and its effect is: in order to regulate the reciprocating stroke size of reciprocating oil cylinder.
Working procedure of the present invention is: under the effect of piston at hydraulic oil, make the spring 12 in piston rod 1 drive pull bar (8) and the pressure spring box 11; When the compressive force of spring 12 during, the valve core displacement commutation of this selector valve, thereby reach the purpose of oil cylinder inner carrier two chamber hydraulic oil commutations, realize the automatic reciprocating motion of hydraulic jack greater than the detent force of selector valve 16.
Claims (3)
1. automatic reciprocating hydraulic oil cylinder, comprise piston rod (1), guide sleeve (3), piston (9), guide ring (10), cylinder body (13) and Sealing, it is characterized in that also comprising the automatic reciprocating mechanism of realization oil cylinder, its structure is: the pull bar (8) that is positioned at piston rod (1) inner chamber, the selector valve (16) that links to each other with cylinder body (13) left part, and the spring assembly that is installed in piston (9) left end; Selector valve (16) is two position four-way valves of " O " type location, the left end of this valve cylinder lever connecting rod (8), and selector valve is connected with the spring assembly left end, and the spring assembly right-hand member is connected with pull bar (8) left end.
2. automatic reciprocating hydraulic oil cylinder according to claim 1 is characterized in that: spring assembly is made up of spring case (11) and the spring (12) that is contained in its box, and this spring and pull bar (8) are that formation is controlled the automatic reciprocating parts of oil cylinder.
