Abstract

The invention discloses a workpiece holder in ultrasonic testing equipment and a positioning method. The workpiece holder comprises a base and a workpiece holding structure, a workpiece fixing structure, a holder bottom positioning structure and a holder number area, wherein the workpiece holding structure, the workpiece fixing structure, the holder bottom positioning structure and the holder number area are arranged on the base; the workpiece holding structure is arranged at the middle part of the base; the workpiece fixing structure is arranged at a workpiece holding place of the base; the holder bottom positioning structure is a positioning hole which is formed in the bottom of the base; the holder number area is an area which is obligated at one end of the base. According to the workpiece holder in the ultrasonic testing equipment and the positioning method, the effective positioning of the workpiece welding surfaces in the horizontal and vertical directions and the batch detection of the workpieces can be realized and the detection efficiency is improved; meanwhile, corresponding workpiece holders are provided to the workpieces with different shapes, so that the accuracy of the detection is ensured; through the accurate positioning of the workpieces, more useful information can be obtained.

Description

technical field [0001] The invention relates to a fixture in the field of ultrasonic testing of electric contact welding quality, in particular to a workpiece fixture and a positioning method in ultrasonic testing equipment. Background technique [0002] Ultrasonic testing is a common method in non-destructive testing, and it is also a common testing method for weld quality. Most of the ultrasonic testing is to judge the internal gap and material distribution of the workpiece through the ultrasonic transmission intensity or reflection intensity of the workpiece to be tested. The welding quality of electrical contacts is detected and judged by detecting the reflection intensity of ultrasonic waves on the welding surface. When ultrasonic testing equipment detects the welding quality of electrical contacts, the probe detects the distribution and size of defects through surface scanning. Since the ultrasonic reflection intensity is closely related to the distance from the refle...
