Description

Technical Field

[0001] The invention relates to the technical field of penetrant nondestructive testing, and in particular to a tool and a clamping method for penetrant testing of disc parts. Background Art

[0002] The shapes and structures of aircraft engine parts are becoming more and more complex, the number is increasing, the surface quality requirements are more stringent, the parts materials are expensive, the processing is difficult and the cycle is long. During the penetration test, the parts cannot be stacked or contact each other, resulting in disc parts being tested only one at a time, which seriously restricts the inspection efficiency of disc parts. There is an urgent need to test multiple parts at the same time, and the efficiency needs to be improved urgently. Summary of the invention

[0003] The main purpose of the present invention is to propose a tooling and clamping method for penetrant testing of disc parts, aiming to solve the above technical problems.

[0004] To achieve the above-mentioned purpose, on the one hand, the present invention proposes a tool for penetration testing of disc parts, including a tool frame and a beam assembly arranged on the tool frame; the beam assembly includes a core rod and a protective sleeve sleeved on the core rod; a plurality of annular grooves are arranged on the protective sleeve along the axial direction; a plurality of partition members are hung on the beam assembly, and the partition members are stuck in the annular grooves of the protective sleeve; baffles are arranged at the ends of both ends of the core rod.

[0005] Preferably, the material of the protective sleeve is nylon; and the partition member is made of nylon plate.

[0006] Preferably, the baffle is mounted on the end of the core rod by means of a lifting eye screw.

[0007] Preferably, the tooling frame includes a cross body and a vertical supporting steel plate welded to the cross body; a hanging hole and a beam assembly mounting hole are provided on the upper portion of the supporting steel plate, and the beam assembly mounting hole is located below the hanging hole; the core rod of the beam assembly is inserted into the beam assembly mounting hole and then welded; and the supporting steel plate is located in the middle position of the beam assembly, so that both ends of the beam assembly are cantilevered.

[0008] Preferably, the edge of the hole opening of the installation hole of the beam assembly is chamfered to form a welding groove, and the support steel plate and the core rod are fully welded by groove welding.

[0009] Preferably, the cross body is welded by a first square steel and two second square steels; the two second square steels are respectively welded at the middle position of the two long sides of the first square steel; the first square steel is perpendicular to the second square steel; the upper and lower edges of the welding end of the second square steel are respectively provided with welding grooves, and are fully welded to the first square steel by groove welding; the first square steel is parallel to the crossbeam assembly.

[0010] Preferably, the partition member includes an annular body and a horizontal plate; a vertical plate is integrally formed on the bottom of the annular body; the horizontal plate is bonded to the vertical plate, and the horizontal plate and the vertical plate are in a cross shape; a top plate is integrally formed on the top of the annular body; the annular body is sleeved on the cross beam assembly and stuck in the annular groove of the protective sleeve.

[0011] Preferably, the diameter of the baffle is larger than the diameter of the through hole of the annular body.

[0012] On the other hand, the present invention also provides a clamping method for penetrant testing of disc parts, using the above-mentioned tooling, comprising the following steps:

[0013] S1. Remove the baffle;

[0014] S2, hang the partition member and the parts to be tested on the crossbeam assembly, separate two adjacent parts to be tested by the partition member, and the partition member is stuck in the annular groove of the protective sleeve;

[0015] S3. Install baffles at both ends of the core rod of the crossbeam assembly.

[0016] Preferably, in step S2, when assembling the partition member and the part to be tested, a partition member is used to separate the supporting steel plate of the fixture frame from the part to be tested, and a partition member is used to separate the baffle plate from the part to be tested.

[0017] Due to the adoption of the above technical solution, the beneficial effects of the present invention are as follows:

[0018] (1) By adopting the tooling provided by the present invention, multiple parts to be tested can be installed in one clamping. Two adjacent parts to be tested are separated by a partition member to prevent the parts to be tested from colliding with each other. At the same time, the partition member is stuck in the annular groove of the protective sleeve to play an axial limiting role on the partition member. Since the partition member cannot move axially, the partition member can play an axial limiting role on the parts to be tested to prevent the parts to be tested from sliding.

[0019] (2) In the present invention, the protective sleeve and the partition are both made of nylon, which protects the parts to be tested and avoids scratching or damaging the parts to be tested.

[0020] (3) In the present invention, baffles are provided at the ends of both ends of the core rod, thereby preventing the partition member and the part to be tested from sliding off the crossbeam assembly. BRIEF DESCRIPTION OF THE DRAWINGS
