Abstract
The utility model relates to a hydraulic oil cylinder with the self-sealing and self-guiding effects. The hydraulic oil cylinder with a guide sleeve and with the self-sealing and self-guiding effects comprises a cylinder body, a piston rod, a piston and the guide sleeve. At least one first annular groove is formed in the surface of the outer circle of the guide sleeve, a sealing ring is arranged in the first annular groove, at least one second annular groove which obliquely stretches is formed in the surface of the inner circle of the guide sleeve, and an annular sealing tongue is formed between the second annular groove and the inner hole of the guide sleeve. The structure and the material of a traditional guide sleeve are designed, the guiding effect is achieved, the sealing tongue is additionally arranged, and then the whole hydraulic oil cylinder is reasonable in design, simple in structure, and high in applicability, cost can be lowered, and service life can be prolonged.
Description
Technical field
?the utility model relates to the hydraulic jack of a kind of selfsealings from guiding, is specifically related to a kind of selfsealings self-conductance to the guide sleeve hydraulic jack.
Background technique
Guide sleeve is the critical component of hydraulic jack, and these parts, in the application of hydraulic jack, play two effects, the one, take cylinder tube as the piston rod guiding of benchmark to motion, keep piston rod concentric with cylinder barrel, the 2nd, guarantee the sealing of cylinder barrel and piston rod, form the sealing die cavity of guide sleeve end.Present guide sleeve is that steel and cast iron process form, and for sealing and the guiding that realizes die cavity, at internal circular surfaces, the outer round surface of guide sleeve, processes a plurality of Baltimore grooves, in order to seal ring and guide ring to be installed.The roughness of the concentricity of these Baltimore grooves, dimensional accuracy and working surface requires very high, if do not reach requirement, oil hydraulic cylinder will produce leakage of oil, oil impregnate phenomenon.The application of oil hydraulic cylinder is very wide, greatly to upper kiloton thrust, little of tens thrust-kilograms, the design objective of high-voltage high-speed oil hydraulic cylinder is relatively high a lot, but, low pressure low speed oil hydraulic cylinder is just little much to the requirement of its performance, the manufacture requirement of these parts of guide sleeve relatively, the same comparatively speaking, the employing same process is manufactured, the waste caused, the appearance of guide sleeve selfsealings hydraulic jack, basic change has occurred in its material and structure, reduced processing request, reduced cost of production, because the seal point on guide sleeve seldom, improved sealability, guidance quality is more stable.
The model utility content
The purpose of this utility model is the problem and shortage for above-mentioned existence, provides a kind of reasonable in design, simple in structure, and the strong selfsealings self-conductance of applicability is to the guide sleeve hydraulic jack.
For achieving the above object, the technological scheme of taking is:
A kind of selfsealings self-conductance is to the guide sleeve hydraulic jack, comprise cylinder body, piston rod, piston and guide sleeve, described guide sleeve outer round surface at least is provided with an annular groove one, be provided with seal ring in annular groove one, the guide sleeve internal circular surfaces is provided with at least one annular groove two that tilts to extend, and forms a ring packing tongue between annular groove two and guide sleeve endoporus.
Described guide sleeve internal circular surfaces outer end is provided with annular groove three, also is provided with seal ring in annular groove three.
Described guide sleeve internal circular surfaces inner end is provided with at least one annular groove four, and the cross section of annular groove four is semicircle.
The outer end of described guide sleeve is provided with the guide sleeve backing plate.
Described guide sleeve adopts macromolecule resin material to make.
Described ring packing tongue and piston rod are interference fit, and the end of ring packing tongue is with respect to piston rod cylindrical height interference 0.2mm ~ 0.8mm.
Adopt technique scheme, obtained beneficial effect is:
A kind of selfsealings self-conductance of the utility model is to the guide sleeve hydraulic jack, design by the structure and material to the traditional direction cover, when playing leading role, set up sealed tongue, make whole hydraulic jack reasonable in design, simple in structure, applicability is strong, can reduce costs, improve working life simultaneously.
