Self-locking pipeline piece vibration test auxiliary device and self-locking pipeline piece vibration testing machine

Abstract

The invention relates to a self-locking pipeline piece vibration test auxiliary device and a self-locking pipeline piece vibration testing machine. The self-locking pipeline piece vibration test auxiliary device comprises a front vibration base and a rear vibration base which are arranged at intervals along the front-back direction; the front vibration base is provided with a front long hole, thecenter line of the front long hole extends in the front-back direction, and the front long hole is formed in the direction perpendicular to the front-back direction; the rear vibration base is provided with a rear long hole, the center line of the rear long hole extends in the front-back direction, and the rear long hole extends in the direction perpendicular to the front-back direction; a front sliding sleeve is arranged in the front long hole, a rear sliding sleeve is arranged in the rear long hole, the front sliding sleeve is in limiting fit with the front long hole in the forward direction, the rear sliding sleeve is in limiting fit with the rear long hole in the backward direction, a center hole of the front sliding sleeve is used for containing the front end of a self-locking pipeline piece, and a center hole of the rear sliding sleeve is used for containing the rear end of the self-locking pipeline piece; the arrangement directions of the front long hole and the rear long hole are consistent, so that the self-locking pipeline piece vibrates along the extension directions of the two long holes.

Description

technical field [0001] The invention relates to a vibration test auxiliary device for a self-locking pipeline part and a vibration test machine for a self-locking pipeline part. Background technique [0002] Among the various parts of the aircraft, pipeline parts occupy a very important position. Systems such as fuel oil, hydraulic pressure, and environmental control in aircraft involve conduits of different material specifications, different types, and various connection forms. The corresponding design and manufacturing capability level of the piping system directly affects the advanced level and manufacturing efficiency of the final assembly manufacturing. At present, most of the engine pipeline parts of my country's aircraft are connected by cone seals. In order to ensure the reliability of the connection and achieve the effect of anti-loosening, it is necessary to use the method of series fuses to prevent loosening. [0003] However, the above-mentioned connection meth...

Problems solved by technology

[0003] However, the above-mentioned connection method has the following disadvantages: (1) special tools are required to disassemble and assemble the fuse, which is inconvenient to disassemble and assemble. It is easy to maintain; (2) The fuse is a consumable part, and the fuse needs to be re-installed every time it is assembled, and the cost is high; (3) The assembly of the fuse has high requirements, such as the direction and degree of tightness, and requires a high level of personnel skills. Easy for quality control

[0005] How to assess the anti-loosening performance of the above-mentioned self-locking pipeline parts under actual working conditions is a problem that needs to be solved at present, but no self-locking pipe fittings have been found in the prior art.
