Wear-resistant and collision-resistant echo probe for ultrasonic flaw detection

Abstract

The invention discloses a wear-resistant and collision-resistant echo probe for ultrasonic flaw detection, and relates to the technical field of engineering detection. The probe comprises a probe body, a wear-resistant layer, an outer protective cylinder and an inner protective cylinder. The outer surface of the probe body is fixedly sleeved with the wear-resistant layer, the outer protective cylinder is fixed to the outer surface of the wear-resistant layer, the inner protective cylinder is movably inserted into the bottom of the outer protective cylinder, and four bottom plate mechanisms evenly distributed along the circumference are arranged at the bottom of the inner protective cylinder. By arranging the wear-resistant layer and the bottom plate mechanism, the wear resistance of the echo probe is good, by arranging the rubber buffer block, the collision resistance of the echo probe is good, the distance between the echo probe and a workpiece and the angle of the echo probe can be freely adjusted, and the problems that an existing echo probe is not ideal in wear resistance and collision resistance, and the abrasion resistance is poor are solved. And the echo probe is easy to damage in the use process and is inconvenient to adjust.

Description

technical field [0001] The invention belongs to the technical field of engineering detection, in particular to a wear-resistant and collision-resistant ultrasonic flaw detection echo probe. Background technique [0002] Ultrasonic flaw detectors are mainly used to inspect internal defects of metal materials such as forgings, castings, thick steel plates, thin plates, wire rods, pipes, welds, bars, etc., and to measure the thickness of related metal material parts. Ultrasonic probes are generally composed of piezoelectric wafers, shells, The probe is an electroacoustic converter between ultrasonic vibration and electrical oscillation, and is an important part of the sensory organ equivalent to an ultrasonic flaw detector. In ultrasonic flaw detection, the generation and reception of ultrasonic waves is a kind of energy The conversion process, this conversion is realized through the probe, the role of the probe is to convert electrical energy into ultrasonic energy and convert...

Problems solved by technology

[0008] The object of the present invention is to provide a wear-resistant and collision-resistant ultrasonic flaw detection echo probe. By setting a wear-resistant layer and a bottom plate mechanism, the wear resistance of the echo probe is better, and by setting a rubber buffer block, the echo probe The impact resistance of the echo probe is good, and the distance between the echo probe and the workpiece and the angle of the echo probe can be adjusted freely, which solves the problem that the existing echo probe has poor wear resistance and collision resistance. It is easy to be damaged and the echo probe is inconvenient to adjust
