Problems solved by technology

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 of influence

Embodiment Construction

[0020] The present invention will be further described below in conjunction with the accompanying drawings and embodiments, and the present invention includes but not limited to the following embodiments.

[0021] In order to solve the deficiencies of the existing small-diameter catheter weld seam detection, such as low efficiency, poor consistency, and harm to the human body, a system for changing the existing catheter weld seam detection mode is developed, including: X-ray flaw detector 1, Digital detector 2, robot 3, grasping jig 4, jig quick change station 5, focal length adjustment mechanism 6, tray 7, the material can be stainless steel, titanium, pipe diameter Inspection of more than 500 kinds of conduit welds with length less than 800mm.

[0022] The X-ray flaw detector, digital detector and robot are at least located in the lead room.

[0023] The inspector puts the catheter to be inspected on the tray 7 of the upper and lower material levels, and after entering the...

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...
