Abstract

The invention relates to an auto-collimation device for an ultrasonic non-destructive testing probe based on a manipulator and a working method, and is suitable for industrial and mining enterprises.The auto-collimation device for the ultrasonic non-destructive testing probe is provided at the front end of a six-degree-of-freedom joint manipulator, and comprises a bolt base; the bolt base is provided with a plurality of bolt holes connected to the front end of the six-degree-of-freedom joint manipulator; an elastic connecting mechanism is provided at the center of the bolt base; an ultrasonicprobe is connected to the elastic connecting mechanism by means of a probe clamping mechanism; and a plurality of laser distance measuring sensors are arranged around the elastic connecting mechanism. When the ultrasonic probe is in contact with a curved surface during use, a spring in the elastic connecting mechanism is adjusted in a self-adaptive manner to enable the ultrasonic probe to be tightly attached to the surface of a workpiece to be tested; then ultrasonic scanning is started; and the auto-collimation device is compact in structure, convenient to operate and good in use effect, andhas wide practicability in the technical field.

Description

technical field [0001] The invention relates to an ultrasonic probe self-collimation device, in particular to a manipulator-based ultrasonic non-destructive detection probe self-collimation device used in industrial and mining enterprises. Background technique [0002] With the rapid development of modern industrial technology, the use of automated equipment to replace manual methods for flaw detection of curved surface workpieces has become a relatively advanced detection method. The manipulator can automatically complete specific operations according to the internal program, so it can replace manual labor to complete some heavy, complex and dangerous inspection tasks, and has the advantages of high motion precision, high work efficiency, and low operating costs. As a widely used detection technology in the industrial field, ultrasonic nondestructive testing technology is an important means to ensure the processing quality of workpieces and the reliability of workpieces in ...
