Object clamping table for ultrasonic infrared inspection and ultrasonic infrared inspection method

Abstract

The invention provides an object clamping worktable for ultrasonic infrared detection. The object clamping worktable comprises a fixed bottom plate, horizontal guide rods, bottom plate sliding platforms, test piece clamps, an ultrasonic amplitude-variable rod, an amplitude-variable rod clamp, a horizontal sliding rod, a fastening handle, a sliding block, a vertical retractable rod and a retractable outer rod, wherein transverse sliding grooves are formed in the front part and rear part of the top surface of the fixed bottom plate respectively; the two horizontal guide rods are arranged; the bottom plate sliding platforms are arranged at the front end and rear end of each horizontal guide rod respectively; each horizontal guide rod is in transverse sliding match with the two transverse sliding grooves through the bottom plate sliding platforms at the front end and the rear end; one test piece clamp sleeves each horizontal guide rod; the test piece clamps can slide on the corresponding horizontal guide rods; a clamp bolt hole is formed in the back surface of each test piece clamp; the test piece clamps are fixed at setting positions corresponding to the horizontal guide rods throughthe clamp bolt holes and corresponding bolts. By adopting the worktable provided by the invention, fixed installation of the amplitude-variable rod can be finished and the height is adjusted; translation of a detected object in a detection plane also can be realized.

Description

technical field [0001] The invention relates to the technical field of object clamping equipment, in particular to an object clamping workbench for ultrasonic infrared detection and an ultrasonic infrared detection method. [0002] technical background [0003] Ultrasonic infrared thermal wave detection technology, also known as ultrasonic excitation thermal imaging technology or vibration thermal imaging technology, is an active infrared thermal imaging technology that uses ultrasonic energy as an excitation source. Or superficial damaged parts generate heat, and use an infrared thermal imager to shoot at the same time to obtain infrared thermal images. This technology has a good detection effect on the surface, shallow layer and internal crack and delamination of the material, and has a good application prospect. During the inspection, the layout and installation of the thermal imaging camera and the ultrasonic horn need to be designed by itself, and the fixture for fixing...
