Description

Technical Field

[0001] The invention belongs to the technical field of nondestructive testing, and in particular relates to a penetration testing tool and method. Background Art

[0002] Nondestructive testing is a means of inspecting the surface and internal quality of the inspected parts without damaging the workpiece or the working state of the raw materials. Penetrant testing is a detection technology that uses the surface tension of the liquid to detect open defects on the surface of parts. It is one of the five conventional nondestructive testing methods. Penetrant testing is often used to detect surface defects of parts in the manufacturing and maintenance stages of aircraft engines.

[0003] There are a huge number of small perforated parts, and the parts are stacked during penetration testing. There are often the following difficulties in testing such parts: Difficulty 1. Stacking will cause surface scratches on the parts; Difficulty 2. The gaps between the stacked parts are small, and the penetrant may not be able to fully enter the blocked surface. In this case, these surfaces will not be able to detect defects due to insufficient application of penetrant, which will create certain quality risks; Difficulty 3. The developing powder cannot effectively enter the surface of the stacked parts during the imaging process. Even if the penetrant enters the defective part, the penetrant inside the defect will be sucked out and amplified to form a display because there is no developer, causing this part of the defect not to be displayed, resulting in the possibility of missed defects. Therefore, there is a need for a penetration testing tool that can fix multi-perforated parts in large quantities and allow spacing between adjacent parts.

[0004] The patent document with announcement number CN116952965A discloses a fluorescent penetration detection tool with damping platform blades and a method of use. The tool includes: a main frame, a fixing unit and a plurality of bottom support rods. The bottom of the main frame is radially connected to the fixing unit by the bottom support rods to support the bottom load of the tool. The main frame is used for load bearing and mobile fixation, which solves the shaking problem of the blades during transportation. The blades are placed in the fixing unit to ensure that a sufficient number of blades are placed in the blade basket and the blades do not touch each other. Fixing a single blade can effectively prevent the blades from touching each other and reduce bumps between blades. However, the tool has no mesh blocking structure and cannot be used to store parts. At the same time, the tool is suitable for fixing columnar parts, which limits the fixed use of sheet parts.

[0005] The patent document with announcement number CN203998601U discloses a hanging tool for hollow blade penetration detection. It consists of a main frame, a hanging beam, a hook, a hanging ring assembly and a positioning assembly. However, the hanging beam cannot be moved, which is not convenient for adjusting the number of different mounted parts. Summary of the invention

[0033] The technical solution of the present invention is further described below, but the scope of protection claimed is not limited to the description.

[0034] Example:

[0035] like Figures 1 to 9As shown, a penetration testing tool comprises a frame 1, an edge 2, a clamping frame 4 and a penetration rod 5. An opening is arranged at the top of the frame 1, and an edge 2 is arranged on the opening of the frame 1. One end of the clamping frame 4 is hinged to one side of the top of the frame 1 through a hinge 7. The clamping frame 4 can be opened to clamp the penetration rod 5. The penetration rod 5 is connected to the edge 2, and the penetration rod 5 penetrates the frame 1. The clamping frame frame 1 is mainly welded by φ6 stainless steel support rods 11, with 5 support rods 11 in the width direction and 7 support rods 11 in the length direction. The penetration rod 5 can penetrate multiple perforated parts 10 at the same time for penetration testing, and adjacent perforated parts 10 are arranged at a certain distance.

[0036] The edge 2 is a rectangular frame structure formed by welding φ12 stainless steel cylindrical connecting rods. A plurality of grooves 6 are arranged on the edge 2 so that different threading rods 5 can be arranged according to the number of mounted parts and fixed by the plurality of grooves 6 .

[0037] The groove 6 has a V-shaped cross section and is an annular groove arranged around the axis of the cylindrical connecting rod, so that the threading rod 5 and the bent end 51 can be clamped in the groove 6 on the upper and lower sides of the cylindrical connecting rod of the mouth edge 2.

[0038] The piercing rod 5 is made of steel, one end of the piercing rod 5 is a curved end 51, the other end of the piercing rod 5 is a straight end 52, and a bending portion 53 is arranged on the curved end 51, and the bending portion 53 is arranged in a wave shape. The main body of the piercing rod 5 and the curved end 51 can be clamped in the groove 6 of the mouth edge 2, and the clamping position is locked by the bending portion 53 to prevent the piercing rod 5 from rotating or sliding naturally.

[0039] The part 10 is inserted on the insertion rod 5, and one insertion rod 5 can be used to insert multiple parts 10. The bent end 51 of the insertion rod 5 is stuck in the groove 6 of the edge 2 and fixed by the bent end 51. The insertion rod 5 can be removed and turned over when needed. The straight head end 52 of the insertion rod 5 is placed on the groove 6, and the straight head end 52 is not fixed. When the insertion rod 5 inserts the part 10, the straight head end 52 can be lifted to insert the part. After the part 10 is inserted, the insertion rod 5 is put back into the groove 6, and then the clamping frame 4 is used to press the insertion rod 5. The insertion rod 5 can be installed and easily removed. After removal, the penetration detection tooling can also be used to hold other parts.

[0040] The skeleton 1 is a frame structure, and an isolation net 3 with a size of φ1×10×10 is set on the outer wall of the skeleton 1. The isolation net 3 is made of stainless steel, so that the skeleton 1 can be used to store other parts to prevent the parts from falling out of the skeleton 1.

[0041] A handle 9 is provided on the edge 2, and the handle 9 is rotatably connected to the edge 2, so that the handle 9 can be put down for storage. A protective cover can be provided on the handle 9 to improve the comfort of gripping.

[0042] The pressing frame 4 is provided with a fastener 41 , which is arranged on a side away from the hinge 7 .

[0043] The frame 1 is provided with a buckle 8, which locks the compression frame 4 after being connected with the fastener 41 to prevent the compression frame 4 from opening. The buckle 8 is prepared by the prior art, and the buckle 8 is automatically locked after being connected with the fastener 41, and the buckle 8 can be separated from the fastener 41 by pressing the unlocking button on the buckle 8.

[0044] A method for using a penetration testing tool comprises the following steps:

[0045] S1: Before testing the part 10, open the lock 8, lift the straight end 52 of the insertion rod 5 to insert the part, and after the insertion is completed, clamp the straight end 52 of the insertion rod 5 in the groove 6, and then lock the pressing frame 4 with the buckle 8;

[0046] S2: When penetrant testing the part 10, the penetrant testing tool and the part 10 are directly immersed in the penetrant liquid;

[0047] S3: When cleaning the workpiece after the penetration is completed, the outer surface of the part 10 can be cleaned first. After the outer surface cleaning is completed, the clamping frame 4 can be opened, and the straight end 52 of the penetration rod 5 can be lifted. The penetration liquid in the hole of the part 10 of the entire penetration rod 5 can be fully cleaned. After the cleaning is completed, the whole basket can be placed in the drying equipment and the developing tank for development. After the development is completed, the part 10 on the penetration rod 5 can be moved to observe the visible surface.

[0048] The entire tooling can realize the operations of clamping multiple parts at one time and subsequent drying and fixing, effectively solving the difficulty of penetration testing of small sleeve parts.
