Description

Technical Field

[0001] This invention relates to the field of penetrant nondestructive testing technology, and in particular to a tooling and clamping method for penetrant testing of disc-shaped parts. Background Technology

[0002] Aircraft engine parts are becoming increasingly complex in shape and structure, and their numbers are also increasing. The surface quality requirements are becoming more stringent. The materials used in these parts are expensive, and the processing is difficult and time-consuming. During penetrant testing, parts cannot be stacked or in contact with each other, which means that disc-shaped parts can only be tested one at a time. This severely restricts the testing efficiency of disc-shaped parts. The need for simultaneous testing of multiple parts is urgent, and there is an urgent need to improve efficiency. Summary of the Invention

[0003] The main objective of this invention is to provide a tooling and clamping method for penetrant testing of disc-shaped parts, aiming to solve the aforementioned technical problems.

[0004] To achieve the above objectives, on the one hand, the present invention proposes a tooling for penetrant testing of disc-shaped parts, including a tooling frame and a crossbeam assembly disposed on the tooling frame; the crossbeam assembly includes a mandrel and a protective sleeve sleeved on the mandrel; a plurality of annular grooves are spaced apart along the axial direction of the protective sleeve; a plurality of partitions are hung on the crossbeam assembly, and the partitions are engaged in the annular grooves of the protective sleeve; baffles are provided at the ends of the mandrel.

[0005] Preferably, the protective sleeve is made of nylon; the partition is made of nylon sheet.

[0006] Preferably, the baffle is mounted on the end of the mandrel by an eye bolt.

[0007] Preferably, the tooling frame includes a cross-shaped body and a vertical support steel plate welded to the cross-shaped body; the upper part of the support steel plate is provided with a hanging hole and a crossbeam assembly mounting hole, and the crossbeam assembly mounting hole is located below the hanging hole; the mandrel of the crossbeam assembly is inserted into the crossbeam assembly mounting hole and then welded; and the support steel plate is located in the middle of the crossbeam assembly, so that the two ends of the crossbeam assembly are cantilevered.

[0008] Preferably, the edge of the mounting hole of the crossbeam assembly is chamfered, the chamfer forming a welding bevel, and the support steel plate and the mandrel are fully welded by bevel welding.

[0009] Preferably, the cross body is welded by a first square steel and two second square steels; the two second square steels are welded at the middle positions of the two long sides of the first square steel respectively; 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 provided with welding grooves respectively, and are fully welded with the first square steel by means of the groove welding; and the first square steel is parallel to the beam assembly.

[0010] Preferably, the partition piece comprises a ring body and a horizontal plate; a vertical plate is integrally formed on the bottom of the ring body; the horizontal plate is bonded on 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 ring body; and the ring body is sleeved on the beam assembly and clamped in the annular groove of the protective sleeve.

[0011] Preferably, the diameter of the baffle is greater than the diameter of the through hole of the ring body.

[0012] In another aspect, the application further provides a clamping method for penetration detection of disc-shaped parts, which adopts the above tooling and comprises the following steps:

[0013] S1, dismounting the baffle;

[0014] S2, hanging the partition piece and the to-be-detected parts on the beam assembly, and spacing the adjacent two to-be-detected parts by the partition piece, and clamping the partition piece in the annular groove of the protective sleeve;

[0015] S3, mounting the baffles on the two ends of the core rod of the beam assembly respectively.

[0016] Preferably, in the step S2, the partition piece is used to space between the support steel plate of the tooling frame and the to-be-detected parts, and the partition piece is used to space between the baffle and the to-be-detected parts when assembling the partition piece and the to-be-detected parts.

[0017] Due to the adoption of the above technical solutions, the application has the following beneficial effects:

[0018] (1) By adopting the tooling provided by the application, a plurality of to-be-detected parts can be installed at one time, and the adjacent two to-be-detected parts are spaced by the partition piece, which can prevent the to-be-detected parts from colliding with each other, and the partition piece is clamped in the annular groove of the protective sleeve, which plays an axial limiting role on the partition piece. Since the partition piece cannot move axially, the partition piece can play an axial limiting role on the to-be-detected parts to prevent the to-be-detected parts from sliding.

[0019] (2) In the application, the materials of the protective sleeve and the partition piece are both nylon, which plays a protective role on the to-be-detected parts and avoids scratching or damaging the to-be-detected parts.

[0020] (3) In the application, the baffles are provided on the end heads of the core rod, which can prevent the partition piece and the to-be-detected parts from falling off the beam assembly. Attached Figure Description

[0039] Referring to the accompanying drawings, this embodiment provides a fixture for penetrant testing of disc-shaped parts, including a fixture frame 1 and a crossbeam assembly 2 mounted on the fixture frame 1. The crossbeam assembly 2 includes a mandrel 3 and a protective sleeve 4 sleeved on the mandrel 3. Multiple annular grooves 4a are spaced apart along the axial direction of the protective sleeve 4. Multiple partitions 5 are hung on the crossbeam assembly 2, and the partitions 5 are engaged within the annular grooves 4a of the protective sleeve 4. Baffles 6 are provided at both ends of the mandrel 3. The main function of the partitions 5 is to separate the parts to be tested on the crossbeam assembly 2 to prevent damage from impacts. The fixture frame 1 serves as the base of the entire fixture, providing support.

[0040] The protective sleeve 4 is made of nylon; the partition 5 is made of nylon sheet and serves to protect the part under test, preventing scratches or damage. In this embodiment, the baffle 6 is also made of nylon.

[0041] Combination Figure 1 As shown, the baffle 6 is mounted on the end of the mandrel 3 by eye bolts 7. After the part to be tested is clamped in the fixture, the entire fixture can be lifted using eye bolts 7.

[0042] In this embodiment, the tooling frame 1 includes a cross-shaped body and a vertical support steel plate 8 welded to the cross-shaped body. The upper part of the support steel plate 8 is provided with a hanging hole 8a and a beam assembly mounting hole 8b, with the beam assembly mounting hole 8b located below the hanging hole 8a. The mandrel 3 of the beam assembly 2 is inserted into the beam assembly mounting hole 8b and then welded. The support steel plate 8 is located in the middle of the beam assembly 2, making both ends of the beam assembly 2 cantilevered. When lifting the tooling, in addition to using eye bolts 7, it can also be lifted using the hanging hole 8a.

[0043] To ensure the strength of the weld between the mandrel 3 and the supporting steel plate 8, a chamfer 8c is made at the edge of the hole 8b of the crossbeam assembly. The chamfer 8c forms a welding bevel, and the supporting steel plate 8 and the mandrel 3 are fully welded using a bevel welding method.

[0044] In this embodiment, the cross body of the tooling frame 1 is welded from a first square steel 9 and two second square steels 10; the two second square steels 10 are respectively welded at the middle position of the two long sides of the first square steel 9; the first square steel 9 is perpendicular to the second square steels 10; the upper and lower edges of the welding end of the second square steel 10 are respectively provided with welding bevels 10a, and are fully welded to the first square steel 9 by bevel welding; the first square steel 9 is parallel to the crossbeam assembly 2.

[0045] Combination Figure 11 and Figure 12 As shown, the partition 5 includes an annular body 5a and a horizontal plate 5b; a vertical plate 5c is integrally formed on the bottom of the annular body 5a; the horizontal plate 5b is bonded to the vertical plate 5c, and the horizontal plate 5b and the vertical plate 5c form a cross shape; a top plate 5d is integrally formed on the top of the annular body 5a; the annular body 5a is sleeved on the crossbeam assembly 2 and is locked in the annular groove 4a of the protective sleeve 4.

[0046] The diameter of the baffle 6 is larger than the diameter of the through hole in the annular body 5a. This is to prevent the partition 5 from slipping off the beam assembly 2.

[0047] Combination Figure 13As shown, this embodiment also provides a clamping method for penetrant testing of disc-shaped parts, which uses the above-mentioned tooling to clamp the part to be tested, including the following steps:

[0048] S1. Remove baffle 6;

[0049] S2. Hang the partition 5 and the part to be tested on the crossbeam assembly 2. The two adjacent parts to be tested are separated by the partition 5, and the partition 5 is stuck in the annular groove 4a of the protective sleeve 4.

[0050] S3. Install baffles 6 at both ends of the mandrel 3 of the crossbeam assembly 2.

[0051] In step S2, when assembling the partition 5 and the part to be tested, the partition 5 is used to separate the support steel plate 8 of the tooling frame 1 from the part to be tested, and the partition 5 is used to separate the baffle 6 from the part to be tested.
