A sample rod for automatic rotating ultrasonic detection of rods and its use method

Abstract

The invention relates to a sample rod for automatic rotating ultrasonic detection of rods, which comprises a cylindrical rod body, a blind hole is opened at the upper end of one side of the rod body, and a central Horizontal hole, on the rear side of the central horizontal hole, there is a surface short shallow groove on the upper surface of the rod body, and on the rear side of the surface short shallow groove, there is a subcutaneous horizontal hole also located on the upper surface of the rod body, the rear side of the subcutaneous horizontal hole There is a surface long and deep groove on the upper surface, a central horizontal hole in the middle of the rod body is provided on the rear side of the surface long and deep groove, and a near-surface horizontal hole in the lower part of the rod is provided at the rear end of the central horizontal hole. There is a central horizontal hole in the middle of the rod near the rear end of the rod; it has standard shape, reasonable layout of artificial injuries, clear marking, simple structure, comprehensive functions, easy operation, accurate calibration, safety and practicality, and requires no maintenance. Features.

Description

technical field [0001] The invention belongs to the technical field of metallurgical product quality detection, and relates to a sample rod for automatic rotating ultrasonic detection of rods and a use method thereof. Background technique [0002] Water immersion automatic rotary ultrasonic testing is an efficient and accurate internal quality testing process for round bars. The process testing equipment includes automatic ultrasonic testing equipment, sample bars for equipment verification, supporting bar conveying platforms, loading and unloading rollers and Sorting agency. The inspection procedure is: according to the specifications and quality requirements of the rods to be inspected, the reference sample rods are used to calibrate the detection equipment (including probe calibration and sensitivity setting), and then the automatic detection of the rods through the rods is carried out. Among them, the reference sample rod for equipment debugging is the key reference par...
