Embodiment Construction

[0018] to combine figure 1 , figure 2 and image 3 , an ultrasonic flaw detection auxiliary robot, its frame 1 is provided with a frame walking mechanism. The frame traveling mechanism is provided with two magnetic walking crawlers, namely the No. 1 magnetic walking crawler 2 positioned on the left side of the frame and the No. 2 magnetic walking crawler 3 positioned at the right side of the frame. The No. 1 magnetic walking crawler 2 is provided with a sprocket wheel, a transmission chain 202, a magnetic crawler 203 and a first driving motor 204. The first driving motor 204 is located at the rear side of the frame traveling mechanism, and the magnetic walking crawler where it is located is the No. 1 magnetic walking crawler. The rear sprocket 201 in 2 is connected, and the first drive motor 204 drives the sprocket to rotate, and drives the magnetic crawler belt to advance through the transmission chain. The No. 2 magnetic walking crawler 3 is provided with a sprocket whee...

Abstract

The invention discloses an auxiliary robot for ultrasonic flaw detection, which comprises a frame, a frame travel mechanism, a detection executing part, a coupling agent coating part and a moving mechanism for the executing part. In the frame travel mechanism, each pedrail drive motor acts separately or cooperatively to enable the frame to go forward, backward or turn. The detection executing part is moved by a synchronous belt in the moving mechanism for the executing part. A probe rotating motor and an ultrasonic probe clamping part are arranged on an internal mounting bracket. An ultrasonic probe clamping part is moved up and down by a linear reciprocating motor through the internal mounting bracket. In the coupling agent coating part, a coupling agent brush is fixed on the ultrasonic probe clamping part. The coupling agent brush coats the coupling agent in the front, and then the ultrasonic probe executes the process of flaw detection behind the coupling agent brush. The invention accomplishes heavy works such as coupling agent coating, probe clamping and the like per se, which greatly reduces labor intensity of detectors and improves the efficiency and precision of detection.

Description

technical field [0001] The invention relates to an auxiliary device for ultrasonic flaw detection, that is, to an auxiliary robot for ultrasonic flaw detection. Background technique [0002] Ultrasonic flaw detection has the following characteristics: good directionality, relatively high strength, reflection, refraction and waveform conversion at the interface of two propagation media, strong penetrating ability, and no harm to the human body. Ultrasonic flaw detection is one of the non-destructive testing methods commonly used in the manufacturing process of pressure vessels, shipbuilding, boilers and other equipment. Especially in the welding seam flaw detection in the pressure vessel manufacturing process, the manual detection method is mainly used, which has the disadvantages of low work efficiency, insufficient detection accuracy and high labor intensity. In addition to the preparatory work such as the determination of flaw detection requirements and the adjustment of ...
