Description
Technical field
The utility model relates to eddy current flaw detec field, is specially a kind of three axial curve motions that can be used for detecting non-standard surface of workpiece defect.
Background technology
One of EDDY CURRENT is many NDT(Non-Destructive Testings) method, the basis that its application " electromagnetics " basic theories detects as conductor.The generation of eddy current comes from a kind of phenomenon being called electromagnetic induction.When alternating current is applied to conductor, such as, on copper conductor time, magnetic field produces magnetic field by conductor and around in the space of conductor.Eddy current is exactly the electric current that induction produces, and it flows in a loop.Why be called " eddy current ", be because it with liquid or gas-circulating barrier in the loop forma fluens be the same.If a conductor to be put into the magnetic field of this change, eddy current will produce in that conductor, and eddy current also can produce the magnetic field of oneself, rise along with alternating current and expand in this magnetic field, along with alternating current reduces and blanking.Therefore when conductive surface or nearly surface occur that the properties of defect or measuring metallic materials changes, intensity and the distribution of eddy current will be had influence on, thus the situation of change of eddy current can be detected, and then indirectly can know whether the existence of problem inherent vice and metallicity there occurs change.
Current eddy current flaw detec is on the market a lot, and the desk-top eddy current flaw detec of ECS-338 produced for Nanjing Run Qi detecting instrument company limited, generally comprises an industrial computer, an eddy current probe and a set of motion.Detection workpiece in, allow probe uniform motion relative to surface of the work, judged the defect of surface of the work by the inductive loop field on eddy current probe.The relative motion of probe and surface of the work has two kinds of methods at present: one is workpiece motion s, probe stationary; One is that workpiece is static, probe movement.But in its motion of eddy current flaw detec be at present on the market no matter probe or workpiece all can only do straight line or self rotary motion, so existing instrument can only detect plate or the good bar of verticality of surfacing, then cannot detect for the irregular metal works of surface configuration.
Utility model content
The technical problems to be solved in the utility model is to provide the three axial curve motions being applicable to eddy current flaw detec, can detect for the curved surface of different workpieces and out-of-flatness face.
For solving the problem, a kind of three axial curve motions being applicable to eddy current flaw detec of the utility model design, comprise underframe plate and eddy current probe, and described underframe plate is provided with fixture assembly and probe driving mechanism assembly;
Described fixture assembly comprises two clamping plate, and clamping plate are provided with workpiece rotating mechanism and drive motor, described probe driving mechanism assembly is by support, X-axis slide rail, Z axis slide rail, probe servo mechanism forms, described X-axis slide rail is installed on support, X-axis drive motor X-axis slide rail is equipped with, described Z axis slide rail is equipped with Z axis drive motor, Z axis slide rail is flexibly connected with X-axis slide rail and along X-axis track of sliding track bilateral reciprocation, described probe servo mechanism is flexibly connected with Z axis slide rail and pumps along Z axis track of sliding track, probe servo mechanism is made up of rotating disk and motor, described eddy current probe to be fixed on rotating disk and to extend rotating disk downwards, eddy current probe is with turntable rotation and perpendicular to the tangential direction on workpiece for measurement surface.
The beneficial effects of the utility model are: the clamp rotating mechanism in the utility model at the uniform velocity rotates by workpiece self, pop one's head in simultaneously and can to slide on X-axis slide rail and Z axis slide rail with probe driving mechanism assembly, thus carry out curvilinear motion, pop one's head in vertical with the surperficial tangential direction of workpiece for measurement with the maintenance of turntable rotation moment simultaneously, guarantee accuracy of detection, reduce error; The utility model has expanded the sensing range of eddy current flaw detec, the more existing probe movement mechanism can only detecting the eddy current testing instrument of regular flat work pieces or rod-shaped workpiece, mechanism can detect comparatively accurately to different curved surfaces and out-of-flatness face, improve detection efficiency and precision, ensure that the qualification rate of product export, reduce production cost.
Accompanying drawing explanation
Be described in further detail with regard to embodiment of the present utility model below in conjunction with accompanying drawing, wherein:
Fig. 1 is structural representation of the present utility model.
Embodiment
With reference to a kind of three axial curve motions being applicable to eddy current flaw detec shown in Fig. 1, comprise underframe plate 10 and eddy current probe 40, described underframe plate 10 is provided with fixture assembly and probe driving mechanism assembly;
