Description
Technical field
The utility model is related to oil cylinder field, more particularly to a kind of oil cylinder guide sleeve locking device.
Background technology
The external leakage of hydraulic cylinder is one of most common failure mode in cylinder efficient, and oil cylinder external leakage is most important
Reason is exactly the loosening of screw thread at guide sleeve, weakens the fit quality of static seal O-ring mating surface, causes oil leak at O-ring.
Therefore it effectively to solve the problems, such as oil cylinder external leakage, just must can prevent threaded guide sleeve from loosening, and do not weaken O-ring mating surface
Fit quality, and reprocessed convenient for the dismounting of oil cylinder.
The preceding most common locking mode of oil cylinder threaded guide sleeve：Cylinder barrel outer circle locking slot is caught in screw thread by external force percussion
Guide sleeve spanner slot, the percussion of external force inevitably have an impact inner wall of cylinder and guide sleeve outer circle fit quality, certainly will
The static seal effect of first of waterproof O-ring can be weakened, and then considerably increase the external leakage risk of oil cylinder.
In addition, when quality problems occurs in oil cylinder, when needing dismounting inspection, the locking mode for locking slot type is unfavorable for oil cylinder
Dismounting is reprocessed, and external force is still needed to tap deformed spanner slot, cylinder barrel is caused to scrap, and increases production cost.
Invention content
The utility model can be solved effectively mainly solving the technical problems that provide a kind of oil cylinder guide sleeve locking device
Certainly oil cylinder leakage problem, simple in structure, easy for installation, manufacture is at low cost.
In order to solve the above technical problems, the technical solution that the utility model uses is：A kind of oil cylinder is provided to be oriented to
Locking device is covered, including cylinder barrel and the guide sleeve being threaded on cylinder barrel, retainer nut is threaded on the cylinder barrel,
The retainer nut is located at outside guide sleeve, and the retainer nut is equipped with trip bolt, and the trip bolt passes through stop spiral shell
Mother is connected with guide sleeve.
In one preferred embodiment of the utility model, the retainer nut is equipped with radial screw bore, the fastening spiral shell
Nail is connected across radial screw bore with guide sleeve.
In one preferred embodiment of the utility model, the radial screw bore is located at the upper end of guide sleeve.
In one preferred embodiment of the utility model, the stop screw thread is internal thread, and the cylinder barrel outer wall is outer spiral shell
Line.
In one preferred embodiment of the utility model, the retainer nut and guide sleeve are clearance fit, and gap is
1-2mm。
The beneficial effects of the utility model are：The utility model oil cylinder guide sleeve locking device, can effectively solve the problem that oil
Cylinder leakage problem, simple in structure, easy for installation, manufacture is at low cost.
Description of the drawings
It is required in being described below to embodiment in order to illustrate more clearly of the technical scheme in the embodiment of the utility model
Attached drawing to be used is briefly described, it should be apparent that, the accompanying drawings in the following description is only some realities of the utility model
Example is applied, it for those of ordinary skill in the art, without creative efforts, can also be according to these attached drawings
Other attached drawings are obtained, wherein：
Fig. 1 is the structure diagram of one preferred embodiment of the utility model oil cylinder guide sleeve locking device；
Fig. 2 is the right view of Fig. 1；
Fig. 3 is the partial structural diagram of Fig. 1；
The label of each component is as follows in attached drawing：1st, cylinder barrel, 2, guide sleeve, 3, retainer nut, 4, trip bolt.
Specific embodiment
Below by the technical scheme in the utility model embodiment is clearly and completely described, it is clear that described
Embodiment is only the part of the embodiment of the utility model, instead of all the embodiments.Based on the implementation in the utility model
Example, all other embodiment that those of ordinary skill in the art are obtained without making creative work belong to
The range of the utility model protection.
Referring to Fig. 1, a kind of oil cylinder guide sleeve locking device, including cylinder barrel 1 and is threaded in leading on cylinder barrel 1
To set 2, retainer nut 3 is threaded on cylinder barrel 1, retainer nut 3 is located at outside guide sleeve 2, and retainer nut 3 is equipped with fastening
Screw 4, trip bolt 4 are connected across retainer nut 3 with guide sleeve 2.Retainer nut 3 relies on 1 outer wall of cylinder barrel and is threadedly coupled,
The two nut need to be gap-matched, and retainer nut's screw thread takes tolerance 7H；Cylinder barrel outer wall tolerance takes 6g, cylinder barrel outer wall cutting thread section
Length should ensure that in 10-15mm, and roughness 1.6 or 3.2 is should ensure that before processing screw thread.
In addition, retainer nut 3 is equipped with radial screw bore, trip bolt 4 is connected across radial screw bore with guide sleeve 2
It connects.
In addition, radial screw bore is located at the upper end of guide sleeve.
In addition, stop screw thread 3 is internal thread, 1 outer wall of cylinder barrel is external screw thread.
In addition, retainer nut 3 and guide sleeve 2 are clearance fit, gap 1-2mm.In order to which retainer nut 3 can be screwed into
1 outer wall thread of cylinder barrel, necessary (the being less than M2-P2) 1-2mm of the maximum outer circle of guide sleeve 2.
By normal thread M1xP1 (usual tooth is away from P1=1.5/2/3) fitting connections between cylinder barrel 1 and guide sleeve 2；Two
After person's counterface is bonded to each other, retainer nut 3 is screwed into, screw thread M2XP2 is also relied between stop screw thread and cylinder barrel outer wall (usually
Tooth is away from P2=1.5/2/3) connection, stop screw thread inside threading M2XP2-7H, cylinder barrel outer wall threading M2XP2-
6g；In order to ensure effective fitting between 1 outer wall of retainer nut 3 and cylinder barrel, 2 outer circle D1 of guide sleeve need to be less than retainer nut's path
（M2-P2）；Retainer nut 3 is effectively fitted tooth number with 1 outer wall of cylinder barrel only needs 5 teeth, therefore 1 outer wall effective thread of cylinder barrel is long
Degree is in 15mm or so, processing very simple.
The loosening of retainer nut 3 in order to prevent is provided with radial screw hole with 1 overlapping region of guide sleeve in 3 mother of stop spiral shell, uses
To be packed into holding screw 4.Since guide sleeve is usually provided with 3 spanner slots, two holding screws are opened in 3 radial direction of retainer nut
Hole ensures that at least one set screw hole 4 avoids spanner slot.It is preceding to have addressed, since retainer nut 3 is not subject to outer load
Lotus is only responsible for being oriented to the locking of external threading, and therefore, a holding screw 4 is prevented from the loosening of retainer nut 3.
The prior art is different from, the utility model oil cylinder guide sleeve locking device can effectively solve the problem that oil cylinder leakage is asked
Topic, simple in structure, easy for installation, manufacture is at low cost.
The above description is only the embodiments of the present invention, and it does not limit the scope of the patent of the present invention, every
The equivalent structure or equivalent flow shift made using the utility model description is directly or indirectly used in other phases
The technical field of pass, is equally included in the patent within the scope of the utility model.
