Abstract

The invention discloses a metal plate welding seam detection device and method; the metal plate welding seam detection device comprises a sliding block, a pressing plate, a sealing gasket and a downward pressing driving mechanism for driving the pressing plate to descend; the two ends of the sliding block are connected with two connecting rods respectively, the two ends of each connecting rod are provided with fixing claws, and the sliding block is connected with a plurality of elastic positioning rods; the elastic positioning rods are connected with the pressing plate, the sealing gasket is fixed to the lower surface of the pressing plate, and the sealing gasket is located above a welding seam of a metal plate. The sliding block is provided with sliding holes matched with the connecting rods so that the sliding block can slide in the direction of the connecting rods, the connecting rods are provided with sliding grooves matched with the fixing claws so that the two fixing claws can get close to each other or get away from each other, limiting protruding blocks are arranged at the upper ends of the fixing claws, the lower ends of the fixing claws penetrate through the sliding grooves, and the fixing claws are sleeved with nuts so that the fixing claws can be fixed. Complete attachment of the sealing gasket and the metal plate is ensured, and the detection accuracy is improved.

Description

technical field [0001] The invention belongs to the technical field of metal detection, and in particular relates to a metal plate welding seam detection device. Background technique [0002] Weld leakage is one of the problems often encountered in engineering. Any system or component involving liquid (or gas) such as vacuum system, pneumatic system, hydraulic system, etc. may have leakage. Certain airtightness requirements are put forward for these systems or components in the project, and strict airtightness inspections are carried out. [0003] Air tightness testing is also called leak testing, and the airtight performance of seals is one of the important factors affecting product quality. Air tightness testing is a must-check item in the production process for many important parts and assemblies, such as cylinder block, cylinder head, engine assembly, refrigeration system, etc. Existing air tightness detection devices generally have complex structures and large volumes...
