Abstract
The utility model discloses an oil cylinder or cylinder achieving cylinder inner hole single-cylindrical-surface guide. The oil cylinder or cylinder solves the problem that according to an existing device, a certain concentricity error exists. The oil cylinder or cylinder is characterized in that a large cylinder opening guide ring is placed on an inner cylindrical surface at a cylinder opening of an outer cylinder barrel, a middle cylinder opening guide ring is placed on an inner cylindrical surface at a cylinder opening of a middle cylinder barrel, a large cylinder opening positioning groove of a large limiting ring is installed in the cylinder opening of the outer cylinder barrel, and a middle cylinder opening positioning groove of a small limiting ring is installed in the cylinder opening of the middle cylinder barrel. The inner cylindrical surfaces of the cylinder barrels are taken as positioning faces, guide of pistons and the cylinder openings is achieved by means of the inner cylindrical surfaces of the cylinder barrels, and influences of manufacturing errors of a guide sleeve and an installation face of the guide sleeve on the concentricity of a guide surface can be avoided; the large limiting ring and the small limiting ring are used for positioning the large cylinder opening guide ring and a small cylinder opening guide ring and can also limit extending of the cylinder; the design is especially suitable for the oil cylinder or cylinder with a small difference between a cylinder diameter and a rod diameter and especially suitable for a single-action multi-stage cylinder; operation resistance is reduced, abrasion of a moving surface, a sealing part and the like is reduced, and machining is easier to achieve.
Description
Technical field
The utility model relates to a kind of oil cylinder or cylinder, relates to or rather oil cylinder or the cylinder of the single cylinder guiding of a kind of cylinder endoporus.
Background technique
In general hydraulic jack or cylinder, the guiding between the interior outer cylinder of piston rod and cylinder barrel or Multi-stage cylinder, often realizes guiding by guide ring in the guide ring on piston and guide sleeve.And being connected between guide sleeve and cylinder barrel, due to the reason such as processing technology, precision, the guiding annular groove in guide sleeve and cylinder inner cylindrical surface often have certain concentricity, certainly will affect like this guide effect, form larger resistance, consumed energy, unstable wear etc.For this reason, in order to improve the concentricity of different guide surfaces, people, managing to overcome various influence factors, improve machining accuracy by some process meanses, certainly will increase like this some processing costs, but also can only reduce error.
Summary of the invention
The purpose of this utility model is that overcoming the deficiencies in the prior art provides oil cylinder or the cylinder of the single cylinder guiding of a kind of cylinder endoporus, unification utilizes cylinder barrel inner periphery to do locating face, eliminated the impact of oil cylinder or cylinder guidance face concentricity, manufacturing is simple.
The utility model comprises outer cylinder, large piston, large piston guide ring, middle cylinder barrel, small piston, small piston guide ring, piston rod, large guide sleeve, little guide sleeve, it is characterized in that: place vat mouth guide ring at the inner cylindrical surface at the cylinder mouth place of outer cylinder, cylinder mouth guide ring in the inner cylindrical surface at the cylinder mouth place of middle cylinder barrel is placed; In the cylinder mouth of outer cylinder, offer vat mouth locating slot, large limited ring is installed in vat mouth locating slot; In the cylinder mouth of middle cylinder barrel, offer middle cylinder mouth locating slot, little limited ring is installed in middle cylinder mouth locating slot.
Described outer cylinder and middle cylinder barrel are realized guiding by large piston guide ring, vat mouth guide ring, and middle cylinder barrel and piston rod are realized guiding by small piston guide ring, middle cylinder mouth guide ring; Described large limited ring is to vat mouth guide ring location, and little limited ring centralizing cylinder mouth guide ring is located.
As shown from the above technical solution, the utility model: the vat mouth guide ring at cylinder mouth place, middle cylinder mouth guide ring are shifted out to guide sleeve, directly be placed in cylinder barrel inner cylindrical surface, utilize cylinder barrel inner periphery to do locating face, rely on cylinder barrel inner cylindrical surface self to realize two guiding of piston and cylinder mouth, the impact of the foozle that can avoid guide sleeve and attachment face thereof on guide surface concentricity, the guide ring at piston place all contacts with cylinder barrel internal surface with the guide ring at cylinder mouth place; Described large and small limited ring is except giving large and small cylinder mouth guide ring location, and the also position-limiting action that is extended with to cylinder, prevents from squeezing bad cylinder mouth guide ring.The utility model is specially adapted to cylinder and bar footpath poor less oil cylinder or cylinder, as mine individual hydraulic prop etc., is particularly useful for single-acting Multi-stage cylinder; The single cylinder guiding of cylinder endoporus has been eliminated the impact of oil cylinder or cylinder guidance face concentricity, can reduce running resistance, reduce the wearing and tearing to moving surface and Sealing etc., and make processing become simpler.
