Non-contact type detection equipment

Abstract

The invention discloses non-contact type detection equipment. The non-contact type detection equipment comprises a detection device, an X-axis manipulator, a Y-axis transferring platform and a lower adapter board part, wherein the lower end of the Y-axis transferring platform is fixed on the lower adapter board part, and a Y-axis connecting base capable of moving in a Y-axis direction is arranged on the Y-axis transferring platform, the upper end of the Y-axis connecting base is fixedly connected with the lower end of the X-axis manipulator, an X-axis connecting base capable of moving in a X-axis direction is arranged on the X-axis manipulator, one end of the detection device is fixed on the X-axis connecting bas, and the other end of the detection device is provided with a vision detection mechanism and a displacement detection mechanism, which can move in a Z-axis direction respectively. The detection equipment can perform image acquisition and measurement to the polished surface to obtain the size information of the defects of the polished surface and provide data support for repairing, and therefore the non-contact type detection equipment is suitable for undamaged and online three-dimensional detection to a precise surface. the non-contact type detection equipment has a compact structure, the overall equipment dimension and volume are reduced and the detection equipment becomes small in size and convenient to carry, only occupies a small space when in use and is suitable for various working environments.

Description

technical field [0001] The invention relates to the technical field of nuclear power equipment, in particular to a non-contact high-precision three-dimensional detection device for automatic identification and size measurement of surface defects of large components. Background technique [0002] After the surface of large structural parts is ground and polished, it is necessary to detect the defects on the surface for repair. At present, visual inspection, contact detection and online video observation are mainly used to detect the polished surface of large structural parts. However, the detection results of the visual method are easily affected by the subjective judgment of the operator, which affects the measurement accuracy; while in the contact detection method, the probe is easy to scratch the surface to be detected or scratched by the surface; the online video observation method is easy to miss fine scratches . Moreover, the above-mentioned methods can only realize t...

Problems solved by technology

[0004] However, the current equipment used to detect surface defects of large structural parts, in addition to the insufficient detection accuracy and the inability to measure the size of defects, the structure of the equipment itself is relatively complicated, the size and volume of the equipment are large, and it occupies a large space when used. Moreover, most of them are fixed experimental platforms after installation, which is not conducive to the miniaturization and portability of testing equipment, and is also not conducive to use in a working environment with small space; moreover, existing testing equipment is not conducive to the detection of surface defects of large structural parts. It takes a long time to scan, which cannot meet the time requirements of online detection
