An Ultrasonic C-scan Automatic Detection System

Abstract

An ultrasonic C-scan automatic detection system, including a first base, an industrial robot, a water tank, a second base for supporting the water tank, a turntable arranged inside the bottom of the water tank, and a first drive mechanism for driving the turntable to rotate, the first The two bases are erected on the first base, the bottom of the water tank is provided with a through hole, the outer periphery of the through hole is provided with a flange, and the turntable passes through the through hole and protrudes inside the bottom of the water tank; the turntable has a lower socket, The outer wall of the lower socket part is covered with a main shaft, which extends downwards to the outside of the water tank and is driven to rotate by the first driving mechanism. The outer wall of the main shaft is provided with a mounting part, and the upper end of the mounting part extends upwards and is higher than the flange. The lower end extends downward and forms an annular airtight space with the through hole, and the upper end of the main shaft extends upward and is higher than the upper end of the installation part. The advantage of the present invention is that the first base and the second base are arranged independently of each other, even if the bottom of the water tank is slightly deformed due to long-term water storage, it will not affect the mechanical precision of the turntable.

Description

Technical field [0001] The present invention relates to the field of ultrasonic scanning devices, and in particular, to an ultrasonic C scan automatic detection system. Background technique [0002] Digital, image and intelligent detection techniques of ultrasonic C scan automatic detection technology can reduce human factors, can intract the size, shape, and quantitative detection of defects within the internal defects of workpiece, and improve the reliability of detection results. stability. Especially for the missile combat member, the engine housing or the like has a complex type surface of the housing, and the use of ultrasonic C scan automatic detection technology. [0003] Due to the high positioning accuracy of the multi-freedom joint industrial robot, it is possible to move to any position and posture in the fixed space, thereby effectively solving the problem of difficulty to positive problems with complex surface retrofit, and is currently used for ultrasonic C.

Problems solved by technology

[0004] The existing design of the water tank and turntable will cause slight deformation of the bottom due to long-term water storage in the water tank, which will affect the mechanical precision of the turntable; in addition, the detection system has high requirements for the mechanical precision of the turntable. If the radial runout does not meet the requirements, it will lead to large clamping errors of the workpiece, serious left and right drift of the surface echo during the high-speed rotation of the workpiece, and it is difficult to realize the tracking of the curved surface of the workpiece by the industrial robot and the automatic alignment of the ultrasonic sound beam ; In view of this, it is necessary to provide a new ultrasonic C-scan automatic detection system
