Embodiment

[0028] A device for ultrasonically detecting the surface morphology of high-nitrogen steel mounted on a mechanical arm. The surface size of the high-nitrogen steel used is 100mm×350mm. The detection steps are as follows:

[0029] The ultrasonic transceiver device is fixed on the robot arm 9 with a flexible clamp, and the walking path planning of the robot arm 9 is performed on the robot control panel 10 .

[0030] The surface size of the tested component is 100mm×350mm, so the pulse generator 1 is used to set the pulse repetition frequency to 500HZ, the ultrasonic transducer 2 is excited to emit ultrasonic waves vertically to the tested sample, and the timer 4 is triggered to start timing.

[0031]Place the high-nitrogen steel components on the same horizontal platform as the robot. The planning path takes the x direction as the scanning direction, and the y direction as the offset direction. At the same time, check whether the ultrasonic transceiver device is perpendicular to...

Abstract

The invention provides a device loaded on a mechanical arm for ultrasonically detecting the surface topography of an additive component. The device comprises a multi-joint-type industrial robot, a robot control panel and a robot power supply which are connected; the multi-joint-type industrial robot is placed on a working platform, and an ultrasonic receiving and transmitting device is loaded on the robot arm to multi-dimensionally move; and a signal collecting card for storing data is connected with a computer system, a computer receives N workpiece surface ultrasonic signals, three-dimensional height information of all points on the surface of a workpiece is calculated according to a constructed microphone array algorithm, and thus a two-dimensional rainbow graph based on the detected surface topography of the additive workpiece is constructed. The device combines a traditional ultrasonic detection system with a computer array algorithm and the industrial robot, the ultrasonic detection system ultrasonically detects the surface topography of the component in a multi-dimensional space comprehensively, accurately and quickly, finally the intuitive and clear two-dimensional rainbowgraph can be obtained, and the surface topography of the workpiece is convenient to analyze.

Description

technical field [0001] The invention belongs to the field of non-destructive testing, and in particular relates to an ultrasonic testing device for surface topography of additive components mounted on a mechanical arm. Background technique [0002] Additive manufacturing technology superimposes each layer of "sheets" to form three-dimensional solid parts, and realizes the manufacture of complex structures that are difficult or impossible to process by traditional techniques. However, after the parts are stacked layer by layer, the quality of each layer cannot be accurately determined. Inspection, and the quality of each layer and the bonding quality between layers directly determine the quality of the entire part. Therefore, the key lies in the surface topography of each layer of "thin slices", and its complexity often leads to problems such as poor accessibility and large detection blind spots in conventional detection methods, which brings great challenges to non-destructi...
