Abstract
A novel connecting structure of a hydraulic cylinder guide sleeve structurally and mainly comprises a cylinder, a guide sleeve and a spring collar, wherein the inner hole of the cylinder and the excircle of the guide sleeve are in cylindrical surface clearance fit; a ring groove is arranged at the front end of the inner hole of the cylinder; a step with a transitional round angle is arranged on the excircle of the guide sleeve; and the spring collar of a circular-section steel wire is arranged between the ring groove of the cylinder and the transitional round angle of the step of the guide sleeve. The connecting structure has the same function as the known guide sleeve connection structure, and ensures the set function of the oil cylinder; and the connecting structure is simple to process, and has the benefits of low cost and small size.
Description
Affiliated technical field
The utility model relates to the hydraulic element field, the linkage structure between especially a kind of novel hydraulic oil cylinder guide sleeve and cylinder barrel.
Background technique
The hydraulic jack guide sleeve is mounted in the cylinder tube front end, the part that piston rod is led and seals.Known guide sleeve generally be divided into according to itself and the Connecting format of cylinder barrel be threaded, block that key is connected, flange connects three types.Adopt this three kinds of forms, the processing of guide sleeve and cylinder barrel is more complicated all, and the oil cylinder point diameter is strengthened, and can increase the length of oil cylinder simultaneously.Small-sized oil cylinder lower for pressure or that installing space is narrow is necessary to develop a kind of novel guide sleeve linkage structure, reaches that processing is simple, expense is low, the target of compact dimensions.
Summary of the invention
The purpose of this utility model provide a kind of new structure type guide sleeve and with the linkage structure of cylinder barrel, under the prerequisite that guarantees oil cylinder performance and every quality index, realize that oil cylinder processing is simple, processing charges is low, boundary dimension reduces.
For achieving this end, technical solution adopted in the utility model is as follows: this structure mainly is made up of cylinder barrel, guide sleeve, spring collar, it is characterized in that: cylinder barrel endoporus and guide sleeve cylindrical be the cylndrical surface movingly, cylinder barrel endoporus front end has an annular groove, the spring collar of a circular section steel wire is housed in the annular groove, the step of a band knuckle is arranged on the guide sleeve cylindrical, and this knuckle abuts against on the spring collar.The cross section contour of cylinder barrel annular groove is the semi-circumference of center on cylinder barrel endoporus bus.Guide sleeve step transition fillet cross section contour is the quadrant of center on guide sleeve cylindrical bus, and this radius of a circle is identical with the radius of the cross section semi-circumference of cylinder barrel annular groove, and guide sleeve step cylndrical surface radius is not more than the internal diameter of spring collar.The spring collar external diameter is identical with the external diameter of cylinder barrel annular groove, and the radius of spring collar steel wire circular section is identical with the radius of cylinder barrel annular groove cross section semi-circumference, and spring collar has fracture.The screw that screwed pipe joint is installed is arranged, the through hole that has pipe joint to pass on the cylinder barrel on the guide sleeve.
The guide sleeve of this structural type and when using with the linkage structure of cylinder barrel, at first guide sleeve is pushed cylinder barrel from the cylinder barrel front end, make guide sleeve front end roundlet cylinder surpass the cylinder barrel annular groove, after the pressure spring collar makes its external diameter less than the cylinder barrel endoporus, spring collar is pushed the cylinder barrel annular groove, then guide sleeve is pulled outwardly its step transition fillet of sening as an envoy to and contacts, and screw on the guide sleeve and the through hole on the cylinder barrel are aligned, promptly finished being linked and packed of guide sleeve and cylinder barrel with spring collar.During oil cylinder work, spring collar can stop that in-oil cylinder oil liquid pressure releases guide sleeve, through hole on the cylinder barrel prevents that by the pipe joint of installing on the guide sleeve screw guide sleeve from rotating, this linkage structure has been realized and be threaded, block that key connects, flange connects identical effect, guaranteed that oil cylinder has set function.
The beneficial effects of the utility model be following some, cylinder barrel only need be processed annular groove, guide sleeve only needs the step of processing belt knuckle, processing is simple; Spring collar is worth cheap, has reduced the oil cylinder manufacturing expense; Easy to assembly; Oil cylinder front end radial dimension and axial dimension are littler than existing Connecting format.
