Description

Automobile inner pull rod riveting assembly structure Technical Field The utility model relates to the technical field of inner pull rod assembly, in particular to an automobile inner pull rod riveting assembly structure. Background In the manufacture of automobiles, the quality of assembly of the inner tie rod directly affects the steering performance and safety of the automobile. The prior inner pull rod assembly structure, such as CN209800526U, discloses a ball head shell of an automobile steering pull rod. However, in the assembly process of the inner pull rod assembly structure, the assembly efficiency is low, the fitting between the parts is not tight, the abrasion is serious due to the direct friction of the metal parts, and the service life and the performance stability of the inner pull rod of the automobile are affected. Disclosure of utility model The utility model aims to solve the technical problem of overcoming the defects in the prior art and providing an automobile inner pull rod riveting assembly structure. The technical scheme adopted by the utility model is as follows: A riveting assembly structure of an automobile inner pull rod comprises a shell with a U-shaped section, wherein a layer of lining is filled on the inner surface of the shell, a rod body of the inner pull rod is arranged on a clamping tool, a ball head of the inner pull rod is riveted into the shell from top to bottom, the lining is arranged between the ball head and the shell at intervals, an opening at the top of the shell is folded inwards to form a rolling opening close to the ball head, and an extrusion cambered surface matched with the opening at the top of the shell is arranged on the inner surface of the clamping tool. According to the technical scheme, the clamping tool drives the inner pull rod to be riveted with the shell, the ball head and the shell are arranged at intervals through the bushing to realize interference fit, the opening of the shell is formed by one-step machining through the extrusion cambered surface of the clamping tool, and the working efficiency is high. In addition, the above-mentioned automobile inner pull rod riveting assembly structure according to the utility model can also have the following additional technical characteristics: According to one embodiment of the utility model, the bushing is a plastic shell with a U-shaped section, and the inner surface of the bushing is a spherical surface matched with the ball head. In addition, the plastic has a certain buffering effect, direct friction between metal parts is avoided, riveting is facilitated, and the service life of the post-working is prolonged. According to one embodiment of the utility model, the bushing is of unitary or split construction. In this technical scheme, integral type bush simple structure, the wholeness is good, simple to operate reduces the assembly degree of difficulty and cost.
