Abstract

The invention discloses a honeycomb thread-repairing connecting component with controllable preload and the usage of the connecting component, and the honeycomb thread-repairing connecting component with the controllable preload and the usage of the connecting component include a weight-reducing bolt (1) and a preload-controllable nut (2). The weight-reducing bolt (1) is passed through the honeycomb hole (14) to be repaired, and then put into the preload-controllable nut (2). A hexagonal spanner wrench wrenches a hexagonal head (11) of the preload-controllable nut (2) until breaking down the hexagonal head (11) of the preload-controllable nut (2) at the position of a broken neck groove (10), namely until reaching an expected installation preload value. The honeycomb thread-repairing connecting component with the controllable preload reduces the total quality of the connecting component and satisfies the very beautiful appearance requirements, and has the advantages of high safety and reliability, and convenient to maintain. The honeycomb thread-repairing connecting component with the controllable preload belongs to the best professional thread-repairing connecting component in the honeycomb repairing field.

Description

technical field [0001] The invention relates to a controllable pretightening force honeycomb repair screw connection assembly and a use method thereof, belonging to the technical field of fastening connectors. Background technique [0002] In the design of aircraft parts, high-end fasteners have high technical requirements, good safety and reliability, and are expensive. Especially in some soft material parts that need to be repaired, the most commonly used method is the conventional bolt and nut fastening connection. Although such a link has a simple structure, it is not optimal for the soft material parts at this time. A series of problems such as unattractive appearance, heavy weight, and uncontrollable preload are concentrated. Another example is in the field of honeycomb repair, ordinary bolt and nut connections cannot meet the requirements. [0003] Therefore, there is an urgent need for a controllable pre-tightening force honeycomb repair threaded connection assembl...
