Mutual locking type positioning bolt component

Abstract

A mutual locking type positioning bolt component comprises two or more D-head bolts and a locking and positioning pad, wherein each D-head bolt is provided with a bolt head notch, bolt holes are formed in the locking and positioning pad, the number of the bolt holes is the same as that of the D-head bolts, a locking and positioning reed is arranged beside each bolt hole of the locking and positioning pad, the D-head bolts are installed after penetrating through the locking and positioning pad, and the locking and positioning reeds interfere with the bolt head notches after being folded to prevent the D-head bolts from rotating. According to the mutual locking type positioning bolt component, the locking and positioning reeds can transmit torque and prevent bolt heads from rotating accordingly after being folded, other assembly interference is avoided, wrenching space is not needed, the relative torsional angle positional relations between connecting parts are restrained, and locking effect is good; a lining enables the positions of a base body and a part to be fastened to be adjustable during installation, so that an ideal installing and fastening effect is realized; installation requirements are met, performance is reliable, structure is simple, cost is low, and usage and maintenance are convenient.

Description

technical field [0001] The invention relates to a bolt, in particular to a mutual stop positioning bolt assembly. Background technique [0002] At present, in the design of mechanical parts in the high-tech field, high-end fasteners with multi-functionality and high reliability have high technical requirements, complex structures, difficult processes, and high prices. In modern mechanical design, it is often required to precisely define the relative position between two parts, especially the precise definition of the torsion angle between the two parts, to avoid cold welding and bonding between parts, and the influence of the assembly unit space requires the product to be small in size. The space is large, the turning space of the wrench is as small as possible, and the stop effect is good. High-end solid parts that can effectively protect the base parts, position accurately, and be installed and disassembled quickly and conveniently. Conventional designs to meet the above...

AI Technical Summary

Problems solved by technology

Conventional designs to meet the above requirements require complex mechanical structures and multi-unit designs

In order to solve the above problems, the positioning bolt assembly limits the relative position between the two parts, avoids cold welding, has a large avoidance space, does not require wrenching space, has a good stop effect, can effectively protect the base parts, and has accurate positioning. The installation and disassembly are fast and convenient, but the existing technology cannot meet the basic requirements of reliable performance, simple structure, low cost, and convenient use and maintenance at the same time.
