Abstract

The invention belongs to the technical field of fasteners, and particularly relates to a centering lock bolt pair based on a large-size chamfer. The centering lock bolt pair comprises a screw rod and a first nut, the side face of a first circular truncated cone structure is attached to the large-size chamfer face of a connecting hole of one part, the first nut is rotated, then the side face of a second circular truncated cone structure is attached to the large-size chamfer face of a connecting hole of the other part, the first nut is screwed, and then the two parts are connected together. By arranging the first circular truncated cone structure and the second circular truncated cone structure, the large-size chamfer faces of the connecting holes of the two parts are automatically guided, then automatic centering connection of the two parts is completed, and the connection of the two parts is facilitated; and when the bolt pair is used, the guide function of the bolt pair and the large-size chamfer faces of the connecting holes is adopted, the positioning of two parts is automatically completed in the screwing process, then the workload of connecting the parts with the large-size chamfer face connecting holes is reduced, and then the connection of the parts with the large-size chamfer face connecting holes is facilitated.

Description

technical field [0001] The invention belongs to the technical field of fasteners, in particular to a centering and anti-loosening bolt pair based on large-size chamfers. Background technique [0002] In the process of processing and production, bolt pairs are often used to fix two or more parts together. Bolt pairs include screws and nuts, and sometimes gaskets. When used, the screws pass through the connection holes, and the nuts and screws are tightened to complete the parts. Fixed connection. [0003] When the existing bolt pair connects the parts, it is necessary to use a positioning shaft or other methods to position the parts, which is inconvenient for the connection of the parts. Contents of the invention [0004] In order to make up for the deficiencies of the prior art, the present invention proposes a centering and anti-loosening bolt pair based on large chamfers. The invention is mainly used to solve the problem that when the existing bolt pair connects the pa...
