Problems solved by technology

The cracks and shrinkage defects on the circumferential surface of the piston rod are detected by the eddy current of the detection probe. At present, there is no better way to solve the stability of the piston rod during the detection process. Because the piston rod is generally long and has a large aspect ratio, the detection speed is usu

Abstract

The invention relates to eddy current testing equipment of a piston rod. The eddy current testing equipment comprises a workbench, wherein a storage rack is arranged on one side of the workbench, a feed mechanism, a detection mechanism and a distribution mechanism are arranged on the workbench in sequence in the direction close to the storage rack, a workpiece rotating assembly and a discharge turnover mechanism are arranged on the workbench below the detection mechanism, the workpiece rotating assembly comprises two rotary driving rollers, the discharge turnover mechanism is located between the two rotary driving rollers, and the feed mechanism is connected with the workpiece rotating assembly by virtue of a first guide plate. The eddy current testing equipment has the functions of automatically feeding, automatically detecting and automatically sorting qualified workpieces and unqualified workpieces so as to enter the corresponding storage plate to be stored and has the advantages ofhigh degree of automation and no need of manual detection, and a plurality of probes are arranged so as to detect the workpieces at the same time by sections, so that the detection efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of flaw detection, in particular to a piston rod eddy current flaw detector. Background technique [0002] Piston rod is an important part of mechanical equipment. The quality of piston rod is very important to mechanical equipment. Therefore, piston rod rings used in high-end or important occasions need to be inspected before assembly to ensure quality. In the process of eddy current testing, the classification of qualified products and defective products will be encountered. The cracks and shrinkage defects on the circumferential surface of the piston rod are detected by the eddy current of the detection probe. At present, there is no better way to solve the stability of the piston rod during the detection process. Because the piston rod is generally long and has a large aspect ratio, the detection speed is usually It is relatively slow, and it is difficult to guarantee the efficiency and accuracy of dete...
