Aerospace engine part flaw detection device convenient to move

Abstract

The invention discloses a convenient-to-move aerospace engine part flaw detection device which comprises a base, wheels are installed at the four corners of the bottom of the base, a telescopic frameis welded to the outer wall of the top of the base, an air cylinder is installed on the telescopic frame, and an operation box is installed on the outer wall of the top of the telescopic frame; a first servo motor is installed on the outer wall of one side of the operation box through a bolt, an output shaft of the first servo motor is connected with a two-way screw through a coupler, the two-wayscrew is coaxially sleeved with two threaded sleeves, and vertical rods are welded to the outer walls of the tops of the two threaded sleeves; and anti-skid rubber pads are installed on the upper portions of the outer walls of the sides, close to each other, of the two vertical rods correspondingly, and two sliding ways are formed in the inner wall of the top of the operation box. Due to the arrangement of a second servo motor, a gear, a sliding column, a sliding sleeve and a rack, a flaw detection head can be driven to do reciprocating motion in the horizontal direction through the rotation of the gear, so that the flaw detection range can be widened, and the flaw detection accuracy is improved.

Description

technical field [0001] The invention relates to the technical field of flaw detection devices, in particular to a portable flaw detection device for aerospace engine parts. Background technique [0002] There are three liquid rocket engines at the tail of the space shuttle, called the main engines, which use liquid hydrogen and oxygen as propellants. The structure of the three main engines is exactly the same. The engine has two pre-combustion chambers. Most of the fuel and a small part of the oxidant output by the turbo pump are fuel-rich combustion in the pre-combustion chamber. The temperature of the gas is about 600 to 700 ° C. It is used to drive the turbine, and then discharged into the main combustion chamber and the rest The oxidant is supplemented by combustion to form high-temperature and high-pressure gas that is discharged from the nozzle of the combustion chamber. The three main engines together can provide more than 600 tons of thrust. The working environmen...

Problems solved by technology

[0003] However, when the existing flaw detection device is in use, it cannot clamp and fix different types of parts, resulting in instability during the flaw detection process; and the flaw detection range is small, and it is impossible to perform all-round flaw detection; and the height of the parts cannot be placed according to The height of the flaw detector is adjusted
