Small-diameter conduit weld joint flexible X-ray digital detection system

Abstract

The invention provides a small-diameter conduit weld joint flexible X-ray digital detection system, which is characterized in that an X-ray flaw detector, a digital detector and a robot are arranged in a lead room, and after a lead door is closed, an operator is isolated from the X-ray flaw detector; the digital detector is mounted at the lower end of a focal length adjusting mechanism; the X-rayflaw detector is mounted on the focal length adjusting mechanism and can move up and down; and the robot selects grabbing jigs of corresponding models on a jig quick-change station according to modelsof to-be-detected pipelines and completes replacement, and grabs the pipelines to the position between the X-ray flaw detector and the digital detector according to a preset track, so that X-rays penetrate through guide pipe weld joints to be imaged on the digital detector. According to the small-diameter conduit weld joint flexible X-ray digital detection system, the detection efficiency is improved through automatic detection of various small-diameter conduits, and the consistency of detection results is improved through standardized detection.

Description

technical field [0001] The invention relates to a detection device for the internal quality of the welding seam of a conduit. Background technique [0002] The inspection of the internal quality of small-diameter conduit welds generally uses X-ray film technology combined with manual mode. However, due to the cumbersome technical process of X-ray film technology, including: product logo making and pasting, film cutting, product placement, transillumination, film development, film review and other steps, and each link can only be operated manually. Even if the tooling is designed, it is difficult to ensure the applicable coverage, so that the detection time of the conduit weld increases with the complexity of the conduit space, resulting in low efficiency of the existing detection methods, high labor intensity, and detection results are affected by personnel skills Level has a big impact. Contents of the invention [0003] In order to overcome the deficiencies of the prio...
