Weld joint detection method for electronic tube

A technology for detecting electronic pipe fittings and welding seams. It is applied in the direction of detecting the appearance of fluid at the leak point, using liquid/vacuum degree for liquid tightness measurement, etc., which can solve the problems of low efficiency, unsuitable for electronic pipe fitting detection, and long time. , to achieve good repeatability, avoid misjudgment of weld faults, and fast speed.

Abstract

The invention discloses a weld joint detection method for an electronic tube. A vacuum detection platform is included, the vacuum detection platform is connected with a detection panel via an enclosed telescopic port, an exhausting hole in vacuum communication with the internal of the vacuum detection platform is arranged in the detection panel, a counterweight pedestal is also included, a support rod is arranged on the counterweight pedestal, a fixed body which can move up and down along the support rod is mounted on the support rod, an upper transverse arm and a lower transverse arm are arranged on the fixed body, a guiding block is arranged on the upper transverse arm, the guiding block is provided with a guide groove, and the lower transverse arm is connected with a clamping mechanism. The method can be used to detect weld joints of different types of electronic tubes, and is characterized by high speed, repeatability and reliability.

Description

technical field [0001] The invention relates to the inspection field of electronic pipe fittings, in particular to a method for detecting weld seams of electronic pipe fittings. Background technique [0002] In the production of welded structures, the quality of the welds obtained by the welding technology currently used has not yet reached sufficient stability. Therefore, in order to ensure the quality of the welded components, the quality inspection of the welds must be carried out to ensure that the welds comply with the specified technology. Requirements and safe use of structures. Weld inspection is divided into two categories: non-destructive inspection and destructive inspection. Usually the inspection of welds in production is non-destructive inspection, such as visual inspection, compactness inspection, etc. [0003] Visual inspection of welds has two components. [0004] 1. Inspection of weld shape and size: Weld shape inspection is to use measuring tools to det...
