Abstract
A kind of novel hydraulic cylinder guiding casing connecting structure, the structure are mainly made of cylinder barrel, guide sleeve, spring collar.Inner hole of cylinder and guide sleeve outer circle are the dynamic cooperations in cylindrical surface, and it is the spring collar of circular section steel wire between cylinder barrel annular groove and guide sleeve step transition fillet that, which there is an annular groove in inner hole of cylinder front end, there is the step with knuckle in guide sleeve outer circle,.The connection structure realizes effect identical with well known guiding casing connecting structure, guarantees the set function of oil cylinder.There is the beneficial effect that the processing is simple, low in cost, outer dimension is small simultaneously.
Description
Technical field
Originally it is related to Hydraulic Elements field, the connection structure between especially a kind of novel hydraulic cylinder guide sleeve and cylinder barrel.
Background technique
Guide sleeve for hydraulic oil cylinder is mounted in cylinder tube front end, the part for being oriented to and being sealed to piston rod.It is known
Guide sleeve be divided into threaded connection with the type of attachment of cylinder barrel generally according to it, card key is connect, flanged joint three types.Using
The processing of these three forms, guide sleeve and cylinder barrel is all more complicated, and generally oil cylinder point diameter can also increased, meeting simultaneously
Increase the length of oil cylinder.It is necessary to develop a kind of novel guide sleeve company for small-sized oil cylinder lower for pressure or narrow installation space
Binding structure, reaches that the processing is simple, expense is low, the target of compact dimensions.
Summary of the invention
This purpose is to provide a kind of guide sleeve of new structure type and its connection structure with cylinder barrel, is guaranteeing oil cylinder
Under the premise of energy and every quality index, realizing oil cylinder, the processing is simple, processing charges is low, outer dimension reduces.
For this purpose, this technical solution for being taken is as follows: the structure is mainly by cylinder barrel, guide sleeve, Spring Card
Circle composition, it is characterized in that: inner hole of cylinder and guide sleeve outer circle are the dynamic cooperations in cylindrical surface, there are an annular groove, ring in inner hole of cylinder front end
Slot is provided with the spring collar of a circular section steel wire, there is the step with knuckle, the transition circle in guide sleeve outer circle
Angle abuts against on spring collar.Semi-circumference centered on the cross section contour of cylinder barrel annular groove on inner hole of cylinder bus.Guide sleeve
Quadrant centered on step transition filleted section contour line on guide sleeve outer circle bus, the radius of a circle and cylinder barrel
The radius of the section semi-circumference of annular groove is identical, and guide sleeve stepped cylindrical radius surface is not more than the internal diameter of spring collar.Spring collar
Outer diameter is identical as the outer diameter of cylinder barrel annular groove, the radius and the radius phase of cylinder barrel annular groove section semi-circumference of spring collar steel wire circular section
Together, spring collar is provided with fracture.There is the screw hole of installation screwed pipe joint on guide sleeve, has the through-hole that pipe fitting passes through on cylinder barrel.
The guide sleeve of the structural shape and its with the connection structure of cylinder barrel in use, guide sleeve is pushed away from cylinder barrel front end first
Enter cylinder barrel, making guide sleeve front end small cylindrical surface is more than cylinder barrel annular groove, will after compressed spring retainer ring makes its outer diameter be less than inner hole of cylinder
Spring collar is pushed into cylinder barrel annular groove, and then guide sleeve is pulled outwardly to its step transition fillet of sening as an envoy to contacted with spring collar, and will
The through-hole on screw hole and cylinder barrel on guide sleeve is to just, that is, completing being linked and packed for guide sleeve and cylinder barrel.When cylinder efficient, bullet
Spring retainer ring can stop in-oil cylinder oil liquid pressure to release guide sleeve, and the through-hole on cylinder barrel is by installing on guide sleeve screw hole
Pipe fitting prevents guide sleeve from rotating, make the connection structure realize be threadedly coupled, card key connection, the identical work of flanged joint
With it is set to ensure that oil cylinder has the function of.
This beneficial effect is the following, and cylinder barrel need to only process annular groove, and guide sleeve need to only be processed with knuckle
Step, the processing is simple；Spring collar value is cheap, reduces oil cylinder manufacturing expense；It is easy to assembly；Oil cylinder front end radial dimension and
Axial dimension is smaller than existing type of attachment.
Detailed description of the invention
It elaborates with reference to the accompanying drawing to this structure:
Attached drawing 1 is novel hydraulic cylinder guiding casing connecting structure diagrammatic cross-section.
Attached drawing 2 is spring collar schematic diagram.
Attached drawing 3 is cylinder barrel annular groove partial cutaway section schematic diagram.
Attached drawing 4 is guide sleeve step partial cutaway section schematic diagram
Specific embodiment
In the various figures, 1 is cylinder barrel, and 2 be guide sleeve, and 3 be spring collar, and 4 be guide sleeve connecting socket, and 5 be on cylinder barrel
Through-hole, 6 be spring collar fracture, and 7 be inner hole of cylinder bus, and 8 be cylinder barrel annular groove, and 9 be the cross section contour of cylinder barrel annular groove, 10
It is guide sleeve outer circle bus, 11 be guide sleeve step transition fillet, and 12 be guide sleeve step.
The construction of novel hydraulic cylinder guiding casing connecting structure shown in the drawings is: 1 inner hole of cylinder barrel is with 2 outer circle of guide sleeve
There are an annular groove 8 in the dynamic cooperation in cylindrical surface, 1 inner hole front end of cylinder barrel, and annular groove 8 is provided with the spring collar 3 of a circular section steel wire, leads
There is the step 12 with knuckle 11 in 2 outer circles of set, which abuts against on spring collar 3.Cylinder barrel annular groove
Semi-circumference centered on cross section contour 9 on inner hole of cylinder bus 7.The cross section contour of guide sleeve step transition fillet 11 is
The radius of the section semi-circumference of quadrant of the center on guide sleeve outer circle bus 10, the radius of circle and cylinder barrel annular groove 8
Identical, the radius on 12 cylindrical surface of guide sleeve step is not more than the internal diameter of spring collar 3.The outer diameter and cylinder barrel annular groove 8 of spring collar 3
Outer diameter it is identical, the radius of 3 steel wire circular section of spring collar is identical as the radius of section semi-circumference of cylinder barrel annular groove 8, Spring Card
Circle 8 is provided with fracture 6.There are the screw hole 4 of installation screwed pipe joint, the through-hole 5 for thering is pipe fitting to pass through on cylinder barrel 1 on guide sleeve 2.
