Eddy current detection device

Abstract

The invention discloses an eddy current testing device. The device comprises a workbench, a linear module, a probe and a conveyor belt, x-axis, Y-axis and Z-axis moving mechanisms are symmetrically arranged on the upper end face of the workbench; a turnover mechanism is transversely mounted in the left side of the conveying belt; and another turnover mechanism is longitudinally installed in the right side of the conveying belt, a second rotating air cylinder is fixedly connected to the bottom end of the turnover mechanism located in the right side, an n-shaped plate is fixedly connected to thebottom face of the second rotating air cylinder, a third supporting column is installed on the upper end face of the workbench, and a material guiding groove is fixedly connected to the third supporting column. The device is compact in structure, the problems that a traditional device is complex in structure and low in functionality are solved. In addition, the structure is compact and simple, the manufacturing cost is reduced, detection can be more accurate, comprehensive and uniform, the workpiece detection quality is effectively improved, two sets of XYZ three-axis moving mechanisms are arranged for work division, on one hand, the working efficiency is improved, and on the other hand, unqualified surfaces of the workpieces can be found out.

Description

technical field [0001] The invention relates to eddy current detection equipment, in particular to an eddy current detection device, and belongs to the technical field of eddy current detection equipment application. Background technique [0002] Eddy current flaw detection is a flaw detection method that uses the principle of electromagnetic induction to detect surface defects of components and metal materials. The detection method is to detect coils and their classification and the structure of the detection coils. The principle is to use excitation coils to generate eddy currents in conductive components. The detection coil measures the change of eddy current to obtain the relevant information of component defects. According to the shape of the detection coil, it can be divided into passing type (for the detection of wire, rod and pipe), probe type (for the detection of component surface There are three kinds of local detection) and plug-in type (for internal detection of...

Problems solved by technology

[0011] The purpose of the present invention is to solve the problem that the structure of the existing eddy current detection device is relatively complex, because the probe cannot be moved so it can only detect the rotating body, which is not suitable for square workpieces, has large limitations, and has a complicated structure and manufacturing cost. It is difficult to distinguish which surfaces are unqualified, and the detection efficiency is low, so an eddy current detection device is proposed
