Abstract
The utility model provides a nut with a pressure riveting washer, which comprises a body and a washer; the gasket is riveted at one end of the body, two ends of the body are respectively provided with a slotted nut and a riveting structure which are mutually connected, and the thrust of the slotted nut is transmitted to the riveting structure to deform the gasket after the body is assembled; the utility model has the advantages that the gasket and the nut are separately processed, so that the thickness of the gasket is reduced, and the gasket can be maximally deformed; the washer is riveted on the nut, so that the anti-loosening effect of the nut is increased without additionally adding the washer in the nut assembling process.
Description
Technical Field
The utility model relates to a nut of packing ring is riveted to area pressure.
Background
The slotted nut prevents the nut from loosening through a groove processed on the end face of the slotted nut, and a plurality of slotted nuts and washers are processed together at present to further prevent the nut and the bolt from loosening and simultaneously obtain the effect of preventing the nut body from being worn; however, the nut is a casting, the thickness of the gasket designed when the nut and the gasket are processed into a whole is more than that of a standard gasket, so that the deformation of the gasket integrated with the nut in the using process is not too large and can not bring much counter force to the nut, and only the anti-abrasion effect is achieved.
SUMMERY OF THE UTILITY MODEL
In order to solve the technical problem, the utility model provides a nut of packing ring is riveted to area pressure.
The utility model discloses a following technical scheme can realize.
The utility model provides a nut with a pressure riveting washer, which comprises a body and a washer; the gasket is riveted at one end of the body, the two ends of the body are respectively provided with the slotted nut and the riveting structure which are connected with each other, and the thrust of the slotted nut is transmitted to the riveting structure to deform the gasket after the body is assembled.
The body is provided with a central hole and an annular groove on the inner wall and the outer wall between the slotted nut and the riveting structure respectively.
The center hole is connected with a threaded hole in the slotted nut of the body through a step to form a step hole, and the diameter of the threaded hole is smaller than that of the center hole.
The riveting structure comprises a limiting structure of a gasket, wherein the limiting structure is a groove wall on the side surface of the annular groove, and the groove wall is a conical surface.
The riveting structure also comprises a gasket fixing table for deforming the gasket, and the gasket fixing table is connected with the groove wall to form a cylindrical surface.
And a chamfer is processed at the tail end of the central hole.
The gasket is provided with a center hole with the same size as the center hole, and the edge of the gasket is provided with a riveting edge which is attached to the groove wall after riveting.
The beneficial effects of the utility model reside in that: according to the method, the washer and the nut are processed separately, so that the thickness of the washer is reduced, and the washer can deform to the maximum extent; the washer is riveted on the nut, so that the anti-loosening effect of the nut is increased without additionally adding the washer in the nut assembling process.

Detailed Description
The technical solution of the present invention is further described below, but the scope of the claimed invention is not limited to the described.
A nut with a pressure riveting washer comprises a body 1 and a washer 2; the gasket 2 is riveted at one end of the body 1, two ends of the body 1 are respectively provided with a slotted nut and a riveting structure which are connected with each other, and the thrust of the slotted nut of the body 1 is transmitted to the riveting structure after the assembly so that the gasket 2 deforms.
The body 1 is provided with a central hole 17 and an annular groove 13 respectively on the inner wall and the outer wall between the slotted nut and the riveting structure. The central hole 17 and the annular groove 13 enable the connecting structure between the slotted nut and the riveting structure to be thin-walled, rigidity of the connecting structure is reduced, and the riveting structure can be greatly deformed after the slotted nut is assembled.
The central hole 17 is connected with a threaded hole 18 in the slotted nut of the body 1 through a step 12 to form a step hole, and the diameter of the threaded hole 18 is smaller than that of the central hole 17. Make the nut of this application can with the cooperation of step axle, have certain restriction effect to rocking of nut after centre bore 17 and the axle laminating. The step 12 can guide the end of the shaft, and has certain effect of preventing the nut from being skewed during assembling.
The riveting structure comprises a limiting structure of the gasket 2, namely a groove wall 14 on the side surface of the annular groove 13, wherein the groove wall 14 is a conical surface; the riveted joint structure further comprises a washer fixing stand 16 which deforms the washer 2, the washer fixing stand 16 being connected to the groove wall 14 as a cylindrical surface.
The end of the central bore 17 is machined with a chamfer 15.
The washer 2 is provided with a central hole with the same size as the central hole 17, and the edge of the washer 2 is provided with a riveting edge which is attached to the groove wall 14 after riveting.
According to the nut, after the gasket is riveted, the riveting edge of the gasket is attached to the groove wall 14, when the nut is assembled, the riveting structure is expanded to a certain extent under the extrusion of the step shaft to deform, the fixing table 16 on the riveting structure prizes the riveting edge of the gasket 2, so that the end face of the gasket is not parallel to the end face of the nut, the friction force between the threads of the nut and the threads on the bolt is increased through the reverse force of the gasket 2 to the nut after the gasket is inclined, and the anti-loosening effect of the slotted nut is improved.
