Description

For the sleeve connector that expanding arbor end connects
Technical field
The utility model belongs to the technical field of distending mandrel, specifically relates to a kind of sleeve connector connected for expanding arbor end.
Background technique
Its end of expanding arbor on existing uncoiler and coiling machine adopts sleeve and circular core shaft coupling structure usually, a bearing pin is adopted to position between its middle sleeve and circular mandrel, during expanding arbor works long hours, easily cause being out of shape in the pin shaft hole of bearing pin between sleeve and circular mandrel, when needs are dismantled expanding arbor, often because bearing pin distortion causes maintenance difficult, sometimes need the repair time reaching 1 ~ 2 day, cause the waste of human resources, production run cost is high.
Summary of the invention
In view of this, the purpose of this utility model is to provide a kind of sleeve connector connected for expanding arbor end, this sleeve connector being used for the connection of expanding arbor end by adopting square opening to be connected between mandrel, and fixed by the link in circumferential attachment hole, handling sleeve and mandrel can be carried out fast, reduce repair time and the motion cost of expanding arbor.
In order to achieve the above object, a kind of sleeve connector connected for expanding arbor end of the utility model, comprise the circular cylinder body be connected with mandrel, be provided with the square hole be connected with mandrel in the middle of described cylindrical shell, described cylindrical shell circumference is evenly provided with and is no less than 4 attachment holes be communicated with square hole.
Further, described square hole is set to Octagon square hole, and described Octagon square hole comprises and being evenly arranged and measure-alike four main limits and four secondary, and the length of described four secondary is 1/2 ~ 2/3 of the length on four main limits.
Further, described attachment hole is set to 4 and is arranged in the middle of four main limit inwalls, and described attachment hole is set to tapped hole.
Further, be provided with groove in the middle of described cylindrical shell peripheral outer wall, described tapped hole is arranged in groove.
Further, the thickness of described groove is set to 1/3 ~ 1/2 of cylindrical shell thickness.
The beneficial effects of the utility model are:
The utility model is used for the sleeve connector of expanding arbor end connection by adopting square opening to be connected between mandrel, and fixed by the link in circumferential attachment hole, handling sleeve and mandrel can be carried out fast, reduce repair time and the motion cost of expanding arbor.
Accompanying drawing explanation
Fig. 1 is the plan view of the sleeve connector that the utility model connects for expanding arbor end;
Fig. 2 is the side view of the sleeve connector that the utility model connects for expanding arbor end.
Reference character: 1-cylindrical shell; 2-square hole; 3-attachment hole; 4-groove.
Embodiment
Below in conjunction with accompanying drawing, preferred embodiment of the present utility model is described in detail.
Be illustrated in figure 1 the plan view of the sleeve connector that the utility model connects for expanding arbor end; Be illustrated in figure 2 the side view of the sleeve connector that the utility model connects for expanding arbor end, a kind of sleeve connector connected for expanding arbor end of the utility model, comprise the circular cylinder body 1 be connected with mandrel, be provided with the square hole 2 be connected with mandrel in the middle of described cylindrical shell 1, described cylindrical shell 1 circumference is evenly provided with and is no less than 4 attachment holes 3 be communicated with square hole 2.
The present embodiment by adopting square opening to be connected between mandrel, and is fixed by the link in circumferential attachment hole, can carry out handling sleeve and mandrel fast, reduces repair time and the motion cost of expanding arbor.
Further, preferred described square hole 2 is set to Octagon square hole, described Octagon square hole comprises and being evenly arranged and measure-alike four main limits and four secondary, the length of described four secondary is 1/2 ~ 2/3 of the length on four main limits, preferred described attachment hole 3 is set to 4 and is arranged in the middle of four main limit inwalls, described attachment hole 3 is set to tapped hole, sleeve is fixed on mandrel by 4 tapped holes by the present embodiment, prevent sleeve in mandrel axially vibration, by square hole four secondary inwalls, sleeve is rotated in a circumferential direction along with mandrel, this structure is avoided.
Further, groove 4 is provided with in the middle of preferred described cylindrical shell 1 peripheral outer wall, described tapped hole is arranged in groove 4, the thickness of preferred described groove 4 is set to 1/3 ~ 1/2 of cylindrical shell 1 thickness, this mechanism is conducive to the weight alleviating sleeve, outside the intensity effect not reducing sleeve, reduce the load of expanding arbor.
What finally illustrate is, above preferred embodiment is only in order to illustrate the technical solution of the utility model and unrestricted, although be described in detail the utility model by above preferred embodiment, but those skilled in the art are to be understood that, various change can be made to it in the form and details, and not depart from the utility model claims limited range.
