Abstract

The invention discloses an assembly error ultrasonic detection method, by setting two ultrasonic detection point groups, and setting at least two ultrasonic detection points at intervals in each ultrasonic detection point group, thus, using the same ultrasonic detection point group The energy amplitude of the ultrasonic echo signals at different ultrasonic detection points can directly determine whether there is a rotation error between two assembly workpieces, and the average value of the energy amplitudes of the ultrasonic echo signals of the two ultrasonic detection point groups In this case, it can be judged whether there is a translation error between two assembled workpieces, that is, the assembly error ultrasonic detection method of the present invention can accurately detect the type and direction of the assembly error, and can be used to guide the operator to complete the high-precision assembly work.

Description

technical field [0001] The invention belongs to the technical field of ultrasonic non-destructive testing, in particular to an ultrasonic detection method for assembly errors and an ultrasonic-assisted assembly method for waveguides. Background technique [0002] Magnetron radar uses a waveguide to transmit radar waves, and the waveguide path is composed of a series of waveguide components. This series of waveguide components may come from different manufacturers, and the processing accuracy and assembly accuracy standards of each manufacturer may not be completely consistent. Therefore, in order to be compatible with components supplied by different manufacturers, the gap between the locking and positioning of the components is usually A certain amount of assembly margin is left. It is precisely because of the existence of the assembly margin that it is difficult to equip the waveguide. During assembly, it is required that the inner tube channel of the waveguide assembly ...
