Abstract
The invention discloses a screw barrel connection structure. The screw barrel connection structure comprises a shaft body, a shaft head, a screw barrel and a connection screw. The shaft head is arranged at one end of the shaft body. The screw barrel is used in cooperation with the shaft head and fixedly connected with the shaft head through the connection screw. A knurl is arranged on the outer circumference of the shaft head, and the shaft head is in interference fit with the screw barrel through the knurl. According to the screw barrel connection structure, the shaft head is in interference fit with the screw barrel through the knurl, the shaft head is used in cooperation with the connection screw for fixing the screw barrel, and therefore the screw barrel and the shaft head cannot rotate relatively; an overlapping curve structure can be selected for the knurl to increase the grabbing force, and the overall structure is stable; and because the knurl is convenient to machine, the machining efficiency is improved, and the machining cost is reduced.
Description
Technical field
The present invention relates to the attachment structure of a kind of swivel nut.
Background technology
There is the axle that externally threaded swivel nut is generally used for polished rod coordinate, be fixed on axle, make axle have threaded function；Axle sleeve has plurality of specifications, can select as required, has replaceable after certain versatility, and abrasion, very easy to use；Swivel nut and axle are it is generally required to pass through the respective outer side edges of groove and fin, make swivel nut will not relatively rotate with axle, it is ensured that the stability of connection, but this connected mode needs to process the structure of groove and fin on axle or swivel nut, cause working (machining) efficiency low, and add processing cost.
Summary of the invention
For the technical problem of above-mentioned existence, it is an object of the invention to: propose the attachment structure of a kind of swivel nut.
The technical solution of the present invention is achieved in that a kind of swivel nut attachment structure, comprises axle body, spindle nose, swivel nut and attachment screw；Described spindle nose is arranged on one end of axle body, and swivel nut coordinates with spindle nose, and is connected fixing with spindle nose by attachment screw；Being provided with annular knurl on the excircle of described spindle nose, spindle nose is by annular knurl and swivel nut interference fit.
Preferably, the diameter of described axle body and the external diameter of swivel nut are equal.
Preferably, the annular knurl on described spindle nose is reticulate structure.
Due to the utilization of technique scheme, the present invention compared with prior art has the advantage that
The swivel nut attachment structure of the present invention, spindle nose is by annular knurl and swivel nut interference fit, and swivel nut fixed by the screw that is connected, make swivel nut will not relatively rotate with spindle nose, annular knurl can select reticulate structure to increase grasp, and overall structure is stable, owing to annular knurl is easy to process, improve working (machining) efficiency, reduce processing cost.
Accompanying drawing explanation
Below in conjunction with the accompanying drawings technical solution of the present invention is described further:
Accompanying drawing 1 is the schematic diagram of a kind of swivel nut attachment structure of the present invention.
Detailed description of the invention
The present invention is described below in conjunction with the accompanying drawings.
As shown in Figure 1, a kind of swivel nut attachment structure of the present invention, comprise axle body 1, spindle nose 2, swivel nut 3 and attachment screw 4；Described spindle nose 2 is arranged on one end of axle body 1, and swivel nut 3 coordinates with spindle nose 2, and is connected fixing with spindle nose 2 by attachment screw 4；The diameter of described axle body 1 is equal with the external diameter of swivel nut 3, and when swivel nut 3 coordinates with deeper screwed hole, axle body 1 can be screwed into swivel nut 3, moves without limitation on swivel nut 3；Being provided with the annular knurl of reticulate structure on the excircle of described spindle nose 2, spindle nose 2, by annular knurl and swivel nut 3 interference fit, owing to annular knurl is this area common structure, is therefore not shown in figure.
Above-described embodiment is only for technology design and the feature of the explanation present invention; its object is to allow person skilled in the art will appreciate that present disclosure and to be carried out; can not limit the scope of the invention with this; all equivalence changes made according to spirit of the invention or modification, all should contain within the scope of the present invention.
