Description

Flaw detector with clamping mechanism

Technical Field

The utility model relates to a fault detection equipment technical field especially relates to a defectoscope with clamping mechanism.

Background

The nondestructive inspection is to detect whether there is a defect or non-uniformity in an object to be inspected by using the characteristics of a substance such as sound, light, magnetism, and electricity without damaging or affecting the performance of the object to be inspected, and to give information such as the size, position, property, and quantity of the defect. Compared with destructive detection, the nondestructive detection has the following characteristics. The first is non-destructive, because it will not damage the use performance of the detected object when detecting; secondly, the detection is comprehensive, and as the detection is nondestructive, 100% of comprehensive detection can be carried out on the detected object when necessary, which cannot be achieved by destructive detection; and the third is omnirange, destructive detection is generally only suitable for detecting raw materials, and nondestructive detection does not damage the use performance of the detected object, so that the nondestructive detection device not only can carry out omnirange detection on the raw materials for manufacturing and all intermediate process links until the final product, but also can carry out detection on equipment in service.

In nondestructive flaw detection, ultrasonic flaw detection is a very common detection means, and when columnar equipment is detected, an ultrasonic flaw detector can well detect point-like, linear and planar defects, but the conventional equipment cannot adjust supporting equipment according to the columnar size, cannot ensure the distance between a detection surface and an object to be detected, and cannot effectively clamp the surface of the object to be detected, so that the operation is difficult.
