Abstract

The invention relates to a screw tap device for repairing an internal thread. The screw tap device comprises a screw tap body, a positioning indicator rod and a connecting sleeve. The screw tap body comprises a main part and a plurality of claw parts. Thread parts used for repairing the internal thread are formed on the outer surfaces of the claw parts, a through hole extending in the axis direction of the main part is formed in the main part, and a first joint part is arranged at the position, close to the claw parts, of the through hole. The outer surface of the positioning end of the positioning indicator rod can be connected with the claw parts, and the indicating end can penetrate through the through hole and comprises a second joint part. The connecting sleeve is detachably fixed on the indicating end of the positioning indicator rod, so that the first joint part and the second joint part are mutually jointed and do not rotate relatively. When the connecting sleeve is fastened at the indicating end, the screw tap device can be rotated to repair the internal thread. The screw tap device needs a small operation space.

Description

technical field [0001] The invention relates to the field of mechanical processing, in particular to a tap device for repairing internal threads. Background technique [0002] During the installation process of threaded connectors, due to factors such as improper protection, improper operation, frequent disassembly, and stress assembly, the internal threads of the parts that cooperate with the threaded connectors are easily damaged, which will cause the threaded connectors to fail to continue in the subsequent assembly process. Install. [0003] For an aircraft, each component needs to be installed one by one in a pre-determined order. After installation, the various parts are compact with each other, so as to ensure that the usable space of the aircraft cabin is relatively large. However, when the internal thread of a certain component is damaged after the components are installed in a compact manner, it is difficult for existing tapping tools to repair the internal threa...
