Description
Technical Field
The utility model belongs to the technical field of mechanical connection, concretely relates to prevent pivoted hole axle riveted structure.
Background
In the mechanical connection mode, the mode of axle and jogged joint is many, and wherein one kind connects different components through the riveting mode, and when the subassembly that this kind of riveting mode combination formed received the impact, riveting portion can tensile deformation, will cause riveted structure's not hard up like this, and in the time of serious, axle and hole will rotation each other, and friction and wear finally lead to riveting inefficacy, the subassembly damages.
SUMMERY OF THE UTILITY MODEL
In order to solve the technical problem, the utility model aims at providing an prevent rotatory hole axle riveted structure.
The utility model adopts the following technical scheme for accomplishing the above purpose:
an anti-rotation hole-shaft riveting structure comprises a connecting shaft, wherein the connecting shaft is cylindrical, the upper end face and the lower end face of the connecting shaft are inclined planes, the inclination directions of the upper end face and the lower end face are opposite, two components used for being connected with the connecting shaft in a riveting mode are arranged up and down, the component I and the component II are provided with a cylindrical hole I matched with the connecting shaft, the axis of the cylindrical hole I is overlapped with the axis of the connecting shaft, the upper end face of the cylindrical hole I is an inclined plane matched with the upper end face of the connecting shaft in a riveting mode, the upper end of the cylindrical hole I extends upwards to form a frustum hole I communicated with the cylindrical hole I, the frustum hole I is of a structure with a large upper end and a small lower end, the frustum hole I and the cylindrical hole I are arranged in an eccentric mode, the eccentric angle is β, the included angle of the frustum hole I is α, the cylindrical hole II matched with the connecting shaft II is arranged on the component II, the axis of the cylindrical hole II in a riveting mode, the axis of the conical hole II is riveted with the axis of the frustum hole II, the connecting shaft II, the conical space of the connecting shaft II which is overlapped with the frustum hole II, the connecting shaft II, the conical space of the conical hole II which is overlapped with the connecting shaft, the conical space of the conical hole II, the conical space II, the conical hole II is symmetrically overlapped with the conical space of the conical frustum hole II, the conical space II, the conical hole II, the conical space II.
