Abstract
The invention provides a hydraulic cylinder coupling head which comprises a body, wherein the body has a shaft hole inside; the inner wall of the shaft hole is provided with a thread; the body has a plurality of through holes symmetrically distributed at the periphery of the shaft hole; the body is axially provided with a circle of bosses; and the side wall of the body is provided with two planes. The side wall of the body is provided with the two planes, and the two planes are mutually arranged in parallel; and through the structure, a cylinder cover of the hydraulic cylinder and a cylinder body of the hydraulic cylinder are positioned rapidly and accurately, so that the assembly speed is accelerated, and the production efficiency of the hydraulic device is improved.
Description
Technical field
The present invention relates to a kind of field of mechanical technique, relate 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.
Summary of the invention
The object of the present invention 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 invention provides a kind of oil hydraulic cylinder coupling head, 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 a further improvement on the present invention, the diameter of described axis hole is greater than the diameter of described through hole.
As a further improvement on the present invention, described oil hydraulic cylinder coupling head is through quenching with Subsequent tempering.
As a further improvement on the present invention, described two planes are arranged in parallel.
Compared with prior art, the invention has the beneficial effects as follows: 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 present invention connects the front view in the first embodiment;
Fig. 2 is the sectional view along A-A line among Fig. 1.
Embodiment
The present invention is described in detail below in conjunction with each mode of execution shown in the drawings; but should be noted that; these mode of executions are not limitation of the present invention; those of ordinary skills all belong within protection scope of the present invention 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 invention 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 invention; they are not to limit protection scope of the present invention, allly do not break away from equivalent mode of execution or the change that skill spirit of the present invention does and all should be included within protection scope of the present invention.
To those skilled in the art, obviously the invention is not restricted to the details of above-mentioned example embodiment, and in the situation that does not deviate from spirit of the present invention or essential characteristic, can realize the present invention with other concrete form.Therefore, no matter from which point, all should regard embodiment as exemplary, and be nonrestrictive, scope of the present invention is limited by claims rather than above-mentioned explanation, therefore is intended to include in the present invention 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.
