Automatic ultrasonic flaw detection device for safety detection

Abstract

The invention relates to an automatic ultrasonic flaw detection device for safety detection. The device comprises a base, a top plate, a controller, a detection mechanism, two fixing mechanisms and two supporting columns, wherein the fixing mechanism comprises a telescopic assembly, a telescopic plate, an adjusting assembly and two air cylinders, the adjusting assembly comprises a first motor andtwo adjusting units, the detection mechanism comprises a lifting plate, a lifting assembly, a translation assembly, a translation plate, a probe and a connecting assembly, and the connecting assemblycomprises a connecting plate, a first spring, a pressure sensor and two sliding units. The automatic ultrasonic flaw detection device for safety detection is advantaged in that a workpiece can be conveniently clamped and fixed through the fixing mechanisms, in addition, the detection mechanism is utilized to enable the probe to lean against a surface of the workpiece for moving detection, moreover, probe abrasion caused by too large contact acting force between the probe and the workpiece is avoided, so efficient automatic safety detection is realized, and practicability of the equipment is improved.

Description

technical field [0001] The invention relates to the field of ultrasonic flaw detectors, in particular to an automatic ultrasonic flaw detector for safety detection. Background technique [0002] Ultrasonic flaw detector is a portable industrial non-destructive flaw detection instrument, which can quickly, conveniently, non-destructively and accurately detect, locate, evaluate and diagnose various defects (cracks, looseness, pores, inclusions, etc.) inside the workpiece. It can be used in both laboratory and engineering site. Widely used in boilers, pressure vessels, aerospace, aviation, electric power, petroleum, chemical, offshore oil, pipelines, military industry, shipbuilding, automobiles, machinery manufacturing, metallurgy, metal processing, steel structures, railway transportation, nuclear power, universities, etc. industry.

AI Technical Summary

Problems solved by technology

[0003] When the existing ultrasonic flaw detection device is used, the inspector needs to grasp the detection probe and slide it on the detection surface of the workpiece for detection. The degree of automation is low, and it is impossible to accurately control the force between the probe and the detection surface of the workpiece. The surface of the workpiece is prone to wear, not only that, but during the detection process, the workpiece is likely to vibrate and slide due to the contact with the probe, which affects the measurement, thereby reducing the practicability of the existing ultrasonic flaw detection device
