Background

The penetrant testing (abbreviated as PT), also called penetrant inspection, is a nondestructive testing method for inspecting surface opening defects based on the principle of capillary action. The method is one of five conventional nondestructive testing methods (ray testing, ultrasonic testing, magnetic powder testing, penetration testing and eddy current testing), and is a comprehensive scientific technology.

After a penetrating agent containing fluorescent dye or coloring dye is coated on the surface of the workpiece, the penetrating agent can penetrate into the surface opening defect under the capillary action for a certain time; removing redundant penetrating agent on the surface of the workpiece, drying, and then coating an adsorption medium, namely a developer, on the surface of the workpiece; also under capillary action, the imaging agent will attract the penetrant in the defect, i.e., the penetrant will permeate back into the image; under a certain light source (black light or white light), penetrant traces at the defects are displayed (yellow green fluorescence or bright red), so that the appearance and distribution state of the defects are detected.

Traditional detection is mostly carried out step by step, the washing of metal surface, the spraying penetrant, spraying developer and last observation are separately gone on the operation panel of difference, it is more troublesome to do the penetration detection through this kind of mode, and it is manual spraying mostly to carry out when spraying penetrant and developer to metal surface when metal penetration detects, not only inefficiency to metal surface spraying penetrant and developer through the manual work, but also there is the inhomogeneous problem of paining, penetrant and developer spraying inhomogeneous can produce the influence to metal penetration detection, lead to the testing result inaccurate.

The working principle of the invention is as follows:

when the invention is used, when the penetration test of the cylindrical metal piece is needed, the cylindrical metal piece is placed between the clamping devices, then the second electric push rod 708 is opened, the first connecting rope 717 and the second connecting rope 718 are pulled through the second electric push rod 708, the first clamping plate 709 and the second clamping plate 710 are close to the fixed pipe 702 so as to fix the cylindrical metal piece, after the fixation of the cylindrical metal piece is completed, the electromagnetic valve 602 at the lower end of the storage bottle 600 filled with the cleaning agent is opened, then the pump body 606 is opened to draw out the cleaning agent from the storage bottle 600, then the cleaning agent is sprayed on the surface of the cylindrical metal piece through the spray head 608, the threaded rod 500 is driven to rotate through the second motor 501, the spray head 608 is moved under the action of the sliding block 610, so that the spraying area of the spray head 608 on the cylindrical metal piece is increased, meanwhile, the distance of the spray head 608 from the cylindrical metal piece can be adjusted through the first electric push rod 609, the mutual matching of the sliding block 610 and the first electric push rod 609 can make the spraying of the cleaning agent more uniform, thereby increasing the cleaning effect on the cylindrical metal piece;

after the cleaning is finished, cleaning agent on the surface of the cylindrical metal part is manually erased, then an electromagnetic valve 602 at the lower end of a storage bottle 600 filled with the cleaning agent is closed, the electromagnetic valve 602 at the lower end of the storage bottle 600 filled with penetrating agent is opened to uniformly spray penetrating agent on the surface of the cylindrical metal part through a spray head 608, when the penetrating agent is sprayed, a first motor 100 at the right side of the lower end of a frame 1 is opened, the first motor 100 is started to wind a traction rope 103, so that a workbench 7 moves towards the lower part of a heating cover 8, when the workbench 7 moves to the lower end of the heating cover 8, a third electric push rod 800 is started to cover the heating cover 8 on the workbench 7, then a heating lamp 801 is started to heat the cylindrical metal part, so that the penetrating efficiency of the penetrating agent is increased, after the penetrating agent penetrates into the cylindrical metal part, the heating cover 8 is lifted, then the penetrating agent on the surface of the cylindrical metal part is manually erased, the electromagnetic valve 602 at the lower end of the storage bottle 600 filled with the developer is opened, the developer is sprayed on the surface of the cylindrical metal piece through the spray head 608, the developer reacts with the penetrant, the workbench 7 is moved into the observation chamber 9 after the reaction is completed, the surface of the cylindrical metal piece is observed through the observation mirror 900, when the clamping claw needs to be opened, the second electric push rod 708 is opened, the first connecting rope 717 and the second connecting rope 718 become loose, and the first connecting rope 717 and the second connecting rope 718 become loose and then gradually expand under the action of the first elastic sheet 711 and the second elastic sheet 712.

When the penetration test of the irregular metal piece is needed, the irregular metal piece is placed between the two clamping devices, then the air pump 701 is started to inflate the fixing tube 702, the air filled in the fixing tube 702 can push the connecting rod 714, so that the irregular metal piece is clamped and fixed by the top plate 715, the penetration test of the irregular metal piece can be performed after the fixing of the irregular metal piece is completed, the air in the fixing tube 702 is discharged through the air release valve 703 after the penetration test of the irregular metal piece is completed, and the connecting rod 714 can be restored to the original state under the action of the spring 713 after the air in the fixing tube 702 is discharged.

The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art should be considered to be within the technical scope of the present invention, and the technical solutions and the inventive concepts thereof according to the present invention should be equivalent or changed within the scope of the present invention.
