Description

Technical Field

[0001] The utility model relates to the technical field of casting detection, in particular to a multifunctional hydraulic casting nondestructive detection machine. Background Art

[0002] During the production process, castings often produce casting defects such as pores, shrinkage, shrinkage holes, cracks, etc. These defects will affect the structural properties and product quality of steel castings. In order to avoid unqualified castings, casting products usually need to be non-destructively tested after production. There are many non-destructive testing methods, among which the fluorescence method is one of the non-destructive testing methods. During the test, the casting is pre-coated with fluorescent liquid. After the fluorescent liquid enters the defects such as pores, the fluorescent liquid on the outer surface is wiped off, and then the casting is coated with a developer (the developer can penetrate into the defects of the casting and adsorb the fluorescent powder or agent at the defects). Finally, the operator uses a non-destructive testing ultraviolet flashlight to illuminate the casting. After exposure, the fluorescent tracer adsorbed in the developer will emit visible fluorescence under the irradiation of a high-power LED ultraviolet flashlight, based on which defects or satin flaws on the surface of the casting can be determined and discovered. In the prior art, although manual non-destructive testing ultraviolet flashlights can be used to conveniently perform non-destructive testing on castings, the non-destructive testing ultraviolet flashlight lacks a holding mechanism, so that when manual non-destructive testing ultraviolet flashlights are manually taken for testing in real time, there will be a problem of heavy labor load.

[0003] After searching, the prior art disclosed (Announcement No.: CN220419183U) a non-destructive testing device for castings, which records that "the moving pad is slidably arranged on the top of the testing platform, the top of the moving pad is rotatably connected to the first threaded rod through a bearing, the surface of the first threaded rod is threadedly connected to a threaded sleeve, one side of the threaded sleeve is fixedly connected to a support frame, the bottom of the support frame is fixedly connected to an ultraviolet lamp, the rear side of the support frame is fixedly connected to a light-blocking rubber pad through a bracket, and a moving mechanism is arranged between the testing platform and the moving pad"; the device can adapt to castings of different heights through the cooperation of the second threaded rod, the first threaded rod and the ultraviolet lamp, and can also be used for testing castings of different heights. It moves by itself instead of manual real-time holding, thereby reducing the labor intensity of manual labor. However, the support frame of the device is suspended horizontally with only one end fixedly supported. Subsequently, during long-term use, the suspended end of the support frame will gradually sag under the action of weight, causing the support frame to bend and deform, thereby affecting the normal use of the device. At the same time, the side of the casting to be inspected is usually in the vertical plane, and the ultraviolet lamp of the device only has a good irradiation effect on the horizontal surface of the casting to be inspected, but cannot irradiate the side accordingly, making the detection process of the device not comprehensive enough and interfering with the detection result of the casting to be inspected. At the same time, the focusing effect that can be achieved by the single-sided light-blocking rubber pad of the device is limited. Utility Model Content
