Problems solved by technology

[0002] Sanitary drainage system products based on precision welding technology have very high requirements for welding parts and internal sealing of products. The traditional sealing detection system uses hydraulic method for detection, which not only has low detection efficiency, but also can only express the sensitivity abstractly. It is difficult to directly observe the leak point with the naked eye. Therefore, due to the different observation skills of the leak detection personnel, the detection structure will not be exactly the same. The detection accuracy can only reach 95%, and the defective rate after detection is still very high. , there are often feedbacks from customers about the poor sealing of some products

Abstract

The invention discloses a precision welding product tightness detection device comprising a workbench provided with a plurality of posts. A seal pressing structure is arranged above the workbench, and an automatic pressing and ejecting structure is arranged below the workbench; the seal pressing structure comprises a first cylinder, a supporting plate supporting the first cylinder, cushion irons supporting the supporting plate, a press plate used for pressing the boss portion of a part to be detected, a fixing plate used for fixing the press plate and an edge press plate used for pressing the edge portion of the part to be detected; the automatic pressing and ejecting structure comprises four second cylinders installed at four corners of the workbench, and the piston rods of the second cylinders penetrate the workbench to fix to the fixing plate. The device has the advantages that the detecting efficiency is improved greatly, and the detection accurate rate can be 100%.
