Permeation detection device capable of being continuously used

Technical Field

The utility model relates to the technical field of machine manufacturing, in particular to a device for carrying out continuous infiltration detection operation on batch workpieces.

Background

The penetration test is to attach a dye-containing coloring or fluorescent penetrating agent to the surface of the workpiece, and under the action of capillary action, the penetrating agent penetrates into the opening defects on the surface of the workpiece due to the wetting and capillary action of the liquid. And then removing excessive penetrating agent on the surface of the part, and attaching a layer of thinner developer on the surface of the workpiece. The penetrant in the defect is absorbed again to the surface of the workpiece under the action of capillary action to form an enlarged defect image display, and the image display is usually required to be observed under the environment with certain illumination. The application methods of the penetrating agent mainly comprise four methods, namely: spraying, brushing, dipping and pouring. The dip coating method and the casting method have the characteristics of simple process, lower cost for establishing a production line and the like, and can be widely applied to some occasions for detecting small and medium-sized workpieces. According to the two methods, a large amount of penetrating fluid is consumed, excessive penetrating fluid is easily applied and impurities on a workpiece are easily mixed, and the subsequent penetrating fluid removal process and the waste liquid recovery treatment cost are greatly improved; while conventional dip coating and spray coating methods can save permeate, they often require operation by experienced technicians and concern personnel health protection. The existing automatic spraying and penetrating device is limited to a single working box working mode, and the defects of low efficiency, low machine utilization rate and the like exist.

In summary, there is a need to provide a new and efficient penetration test device that not only retains the advantages of conventional spraying and brushing, but also can utilize the penetration rest time to perform charging, thereby realizing efficient and automatic continuous penetration test operation.
