Angle-adjustable ultrasonic probe device

Abstract

The invention relates to an angle-adjustable ultrasonic probe device. The device comprises a probe, a platform, a probe angle adjusting mechanism and a base; the probe is mounted on the platform, theprobe angle adjusting mechanism comprises at least one angle adjusting unit mounted between the platform and the base; the angle adjusting unit comprises a rotating component and a telescopic drivingmodule fixed on the base; the rotating component is composed of a cardan universal joint, one end of the universal joint is fixed on the platform, and the other end of the universal joint is fixedly connected with a telescopic end of the telescopic driving module, the telescopic driving module performs telescopic movement up and down to drive the universal joint to perform rotating movement, thereby realizing the adjusting of the probe angle. The detection range of the probe is effectively improved through the angle adjusting mechanism, the control on the probe inclination angle is realized, the reliability of the ultrasonic detection is improved, and the labor intensity of detection personnel is reduced.

Description

technical field [0001] The invention belongs to the field of ultrasonic non-destructive testing, in particular to an ultrasonic probe device with adjustable angle. Background technique [0002] Ultrasonic nondestructive testing is a testing method that uses ultrasonic waves to check the surface and internal quality that cannot be detected intuitively without damaging the working state of parts or raw materials. The principle of ultrasonic testing is: if there are defects such as pores, cracks, and delaminations in the metal (there is gas in the defect), when the ultrasonic wave propagates to the interface between the metal and the defect, it will be reflected in whole or in part, and the reflected ultrasonic wave will be received by the probe. , Through the circuit processing inside the instrument, waveforms with different heights and certain intervals will be displayed on the fluorescent screen of the instrument, and the depth, position and shape of the defect in the part c...

Problems solved by technology

This detection method is labor-intensive, and the detection results are affected by factors such as the operator's technical level, fatigue, emotional fluctuations, etc. The detection results are manually recorded by the inspectors according to the indicators indicated by the instrument, and the defect points are manually marked, and the error often occurs. bigger

In addition, for the defective part of the part, it is necessary to fix the probe on the part for a long time to measure various angles, which not only increases the labor intensity of the operator, wastes manpower, but also holds it for a long time, and the position will inevitably change, which will inevitably affect the detection effect
