Description

Cylindrical welding part flaw detection supporting device Technical Field The utility model relates to flaw detection quality control technology, in particular to a cylindrical welding part flaw detection supporting device. Background The outer cylinder of the radiator is generally formed by linear welding along the height (length) direction of the cylinder, and flaw detection is carried out on the linear part of the pipe body by utilizing X-rays after welding. When the product and the column are placed, the supported column is usually observed by naked eyes, so that the position of the supported column is possibly not at the supporting point of the product, the weight of the product is more than 50kg, the column position is inconvenient to adjust when the product is placed, the periphery of the product is not limited after the product is placed, and once the probe touches the inner wall of the product during operation failure, the product is easy to roll over, so that the product is scrapped or a safety hazard is caused. The disclosed technology has different designs for flaw detection of welded pipes, such as patent publication No. CN112881445B, and a welded pipe flaw detection clamping device comprises a supporting mechanism, wherein a clamping mechanism is fixedly arranged at the rear end of the inner side of the supporting mechanism, and the outer surface of the supporting mechanism is connected with a fixing mechanism in a sliding manner. The gear can be rotated through the motor, the supporting sleeve on the outer surface of the motor can rotate in the rotating process, and then the detection head at the front end of the extension plate can detect the pipeline. The device mainly detects the flaw of the circumferential welding (pipe-pipe butt joint) part of the pipe body, and the probe moves along the outer surface of the pipe body, so that the welding seam in the height direction of the outer cylinder of the radiator can not be detected. As another example, patent publication No. CN111457232a discloses a nondestructive inspection device for welded pipe joint, which comprises two limiting rings and two fixing rings, wherein one ends of the limiting rings and the fixing rings are provided with mounting grooves, one ends of the limiting rings and the fixing rings are provided with limiting grooves, the limiting rings are embedded and mounted in the limiting grooves, the top ends of the limiting rings are provided with gear rings in the mounting grooves, one sides of the top ends of the gear rings are meshed with gears, one sides of the fixing rings are provided with gear grooves corresponding to the gears, one ends of the fixing rings are movably provided with driving motors, one ends of the gears are provided with driving grooves corresponding to the output shafts of the driving motors, one ends of the gear rings are provided with horizontal support tables through rotating shafts, and the top ends of the horizontal support tables are movably provided with flaw detectors. The device is mainly used for detecting the flaw of the circumferential weld joint of the pipe body, and for the pipe body with larger weight, the two clamping rings (pipe body clamping) on the limiting ring can not be synchronous when the pipe body is installed, the adjustment difficulty of the standard position of the pipe body is very large, and the flaw detection precision is poor.
