Abstract
The utility model provides a hydraulic cylinder coupling head which comprises a body. A shaft hole is formed inside the body. Threads are arranged on the inner wall surface of the shaft hole. A plurality of through holes are symmetrically formed in the body. The plurality of through holes are symmetrically formed in the periphery of the shaft hole. A circle of bosses are arranged on the body in the axial direction. Two planes are arranged on the lateral wall of the body. According to the hydraulic cylinder coupling head, the two planes are arranged on the lateral wall of the body in parallel, fast and accurate positioning of a cover of a hydraulic cylinder and a cylinder body of the hydraulic cylinder is achieved, assembling speed is improved, and production efficiency of hydraulic devices is improved.
Description
Technical field
The utility model relates to a kind of field of mechanical technique, relates in particular to the oil hydraulic cylinder coupling head in a kind of hydraulic pressure installation.
Background technique
As everyone knows, in hydraulic pressure installation, generally include a coupling head that connects cylinder block and cylinder cover, to play the effect of sealing fluid force feed.It is circular or square that the profile of oil hydraulic cylinder coupling head of the prior art is essentially.The oil hydraulic cylinder coupling head of this structure is not easy accurate location in the practical set process, thereby causes the assembling difficulty, and manufacturing efficiency is lower.
In view of this, be necessary oil hydraulic cylinder coupling head of the prior art is improved, to address the above problem.
The model utility content
The purpose of this utility model is to provide a kind of oil hydraulic cylinder coupling head, its can be fast and the cylinder body of oil hydraulic cylinder accurately locate, thereby improve assembling speed, improve the manufacturing efficiency of hydraulic pressure installation.
For achieving the above object, the utility model provides a kind of oil hydraulic cylinder coupling head, and it comprises a body, described body interior arranges an axis hole, on the internal face of described axis hole screw thread is set, and arranges on the described body and is symmetrical arranged some through holes, described through hole be symmetricly set in described axis hole around
Described body arranges a circle boss along its axial direction, and two planes are set on the sidewall of described body.
As further improvement of the utility model, the diameter of described axis hole is greater than the diameter of described through hole.
As further improvement of the utility model, described oil hydraulic cylinder coupling head is through quenching with Subsequent tempering.
As further improvement of the utility model, described two planes are arranged in parallel.
Compared with prior art, the beneficial effects of the utility model are: two planes are set on the sidewall with body, and two planes are arranged in parallel, by this structure, can realize that the cylinder body of this oil hydraulic cylinder cylinder cap and oil hydraulic cylinder locates rapidly and accurately, thereby improved assembling speed, improved the manufacturing efficiency of hydraulic pressure installation.
Description of drawings
Fig. 1 is that a kind of oil hydraulic cylinder of the utility model connects the front view in the first embodiment;
Fig. 2 is the sectional view along A-A line among Fig. 1.
Embodiment
Below in conjunction with each mode of execution shown in the drawings the utility model is elaborated; but should be noted that; these mode of executions are not limitation of the utility model; those of ordinary skills all belong within the protection domain of the present utility model according to these mode of execution institute work energy, method or structural equivalent transformation or alternative.
Please refer to the drawing 1 is with shown in Figure 2, and wherein Fig. 1 is that a kind of oil hydraulic cylinder of model utility connects the front view in the first embodiment.In the present embodiment, a kind of oil hydraulic cylinder coupling head 100, it comprises: a body 10, described body 10 inside arrange an axis hole 101, screw thread 111 is set on the internal face of described axis hole 101, arrange on the described body 10 and be symmetrical arranged some through holes 20, described through hole 20 be symmetricly set in described axis hole 101 around.Concrete, symmetrically arranged four through holes 20 are set on this body 10.
In the present embodiment, this body 10 arranges a circle boss 102 along its axial direction, and two planes (30a, 30b) are set on the sidewall of described body 10.
Preferably, the diameter of this axis hole 101 is greater than the diameter of described through hole 20.Concrete, this oil hydraulic cylinder coupling head is through quenching with Subsequent tempering, and quenching with Subsequent tempering can improve the integral rigidity of this oil hydraulic cylinder coupling head 100, improves its working life.
As mode of execution preferably, described two planes (30a, 30b) are arranged in parallel.Certainly also can be arranged to mutual structure at an angle with regard to these two planes (30a, 30b).
Above listed a series of detailed description only is specifying for feasibility mode of execution of the present utility model; they are not to limit protection domain of the present utility model, allly do not break away from equivalent mode of execution or the change that the utility model skill spirit does and all should be included within the protection domain of the present utility model.
To those skilled in the art, obviously the utility model is not limited to the details of above-mentioned example embodiment, and in the situation that do not deviate from spirit of the present utility model or essential characteristic, can realize the utility model with other concrete form.Therefore, no matter from which point, all should regard embodiment as exemplary, and be nonrestrictive, scope of the present utility model is limited by claims rather than above-mentioned explanation, therefore is intended to include in the utility model dropping on the implication that is equal to important document of claim and all changes in the scope.Any reference character in the claim should be considered as limit related claim.
In addition, be to be understood that, although this specification is described according to mode of execution, but be not that each mode of execution only comprises an independently technological scheme, this narrating mode of specification only is for clarity sake, those skilled in the art should make specification as a whole, and the technological scheme among each embodiment also can through appropriate combination, form other mode of executions that it will be appreciated by those skilled in the art that.
