Description
Technical Field
[0001] The utility model relates to the technical field of metal pipe repair, in particular to a space positioning fixture used for repairing metal pipelines. Background Art
[0002] There are many metal pipe components on the aircraft, and they are of different shapes. Due to various factors such as sand holes, vibration, corrosion, etc., metal pipe components are often damaged. Once a metal pipe component is damaged, the entire system that it assists will not function properly. Therefore, the repair of metal pipe components is very important.
[0003] The maintenance manuals of various aircraft models have detailed descriptions of the repair methods of metal pipe assemblies, but they all require spatial positioning of the entire metal pipe. If the repair is performed on the aircraft, spatial positioning can be achieved by simply connecting the two ends of the metal pipe to the corresponding pipe joints of the aircraft, and then cutting the pipe section to be repaired from the metal pipe or cutting the pipe section to be repaired from the middle of the metal pipe, and then installing the pre-made new pipe section (the shape of the new pipe section is the same as the shape of the pipe section to be repaired) on the metal pipe, so that the spatial shape of the entire metal pipe after the repair will not change. Therefore, the advantage of repairing metal pipes on the aircraft is that it can ensure that the metal pipe can be installed in place, and it will not touch other parts due to deformation, reducing the stress and friction caused by installation errors of the metal pipe.
[0004] However, the situation on the aircraft is often very complicated, the space is limited, and the construction is difficult. Therefore, the current repair of metal pipes is generally carried out on the ground and then installed on the aircraft. However, the defects of repairing metal pipes on the ground are: when positioning and clamping the metal pipes, it cannot adapt to metal pipes of different rules, and the metal pipes need to be repaired at different angles during the repair process, and the work is cumbersome during disassembly and installation, and the work efficiency is low.
