[0004] The main purpose of the present invention is to propose a tooling and method for detecting whether the profile of the shunt ring lap section is deformed, aiming to solve the above technical problems.

[0005] To achieve the above object, on the one hand, the present invention proposes a tooling for detecting whether the profile of the shunt ring lap section is deformed, including:

[0006] A disc body;

[0007] Support columns, three of the support columns are arranged in a circular and uniform manner on the disc body;

[0008] Positioning blocks, fixedly connected to the bottom ends of the support columns, and on the positioning blocks, there are positioning stop ports for clamping on the reference positioning ring of the casing-type titanium alloy casting;

[0009] Detection base blocks, the detection base blocks are connected to the disc body through rib plate assemblies; on the detection base blocks, there are first detection stop ports for detecting the outer profile of the shunt ring lap section;

[0010] The detecting movable block is installed on the detecting base block, and a second detecting stop is arranged on the detecting movable block for detecting the inner surface of the lap joint section of the flow dividing ring.

[0011] The first detecting stop and the second detecting stop jointly form a detecting groove for clamping on the lap joint section of the flow dividing ring of the titanium alloy casting of the casing type.

[0012] Preferably, two first detecting stops are arranged on the detecting base block, and one detecting movable block is installed at the position of each first detecting stop on the detecting base block; one detecting base block and two detecting movable blocks form two detecting grooves.

[0013] Preferably, the positioning stop includes a supporting surface and an arc surface; the arc surface is used for closely abutting against the inner circular surface of the reference positioning ring; the supporting surface is used for abutting against the top surface of the reference positioning ring.

[0014] Preferably, a mounting stop is arranged on the detecting base block, the detecting movable block is arranged in the mounting stop, and the detecting base block and the detecting movable block are connected by screws.

[0015] Preferably, a screw rod section is arranged at the top of the support column, the screw rod section passes through the disc body from bottom to top and is screwed with a locking nut; a gasket is arranged between the locking nut and the disc body.

[0016] Preferably, the rib plate assembly includes a T-shaped plate, a connecting plate and a connecting seat; the T-shaped plate is fixedly connected with the disc body by bolts; the connecting seat is installed on the top surface of the detecting base block by screws; the connecting plate is installed on the top surface of the connecting seat by screws; the T-shaped plate is placed on the connecting plate and connected by bolts.

[0017] Preferably, a U-shaped weight-reducing groove is formed in the detecting base block.

[0018] Preferably, a plurality of lightening holes are formed in the disc body.

[0019] On the other hand, the present invention also provides a method for detecting whether the surface of the lap joint section of the flow dividing ring is deformed. Using the above-mentioned tooling, the method includes the following steps:

[0020] S1. Place the titanium alloy casting of the casing type to be detected on the plane of the detection table.

[0021] S2. Vertically lower the tooling onto the titanium alloy casting of the casing type so that the positioning stop on the positioning block is clamped on the reference positioning ring.

[0022] S3. Observe whether there is interference between the inner and outer surfaces of the detection groove on the tooling and the overlapping section of the flow splitting ring during the lowering process of the tooling. If there is interference, it indicates that the overlapping section of the flow splitting ring is deformed; if there is no interference, it indicates that the overlapping section of the flow splitting ring is not deformed.

[0023] Preferably, one detection base block and two detection movable blocks on the tooling form two detection grooves. During detection, the two detection grooves are used to detect two opposite overlapping sections of the flow splitting ring on two adjacent support plates simultaneously.

[0024] Due to the adoption of the above technical solution, the beneficial effects of the present invention are as follows:

[0025] (1) By using the cooperation between the detection groove on the tooling and the inner and outer surfaces of the overlapping section of the flow splitting ring, it is possible to accurately judge whether it is deformed, avoiding the problem that the traditional scribing detection method cannot detect the deformation of the overlapping section of the flow splitting ring relative to the reference positioning ring.

[0026] (2) The tooling provided by the present invention adopts a modular design, including a disc body, support columns, positioning blocks, detection base blocks and detection movable blocks. It has a compact structure, is easy to assemble and adjust, and the detection process can be completed only by vertical lowering, with simple and efficient operation.

[0027] (3) Multi-detection point synchronous detection can be realized. Specifically, one detection base block and two detection movable blocks on the tooling form two detection grooves, which can simultaneously detect two opposite overlapping sections of the flow splitting ring on two adjacent support plates, improving the detection efficiency.

[0028] (4) The tooling has high stability and positioning accuracy. The positioning stop on the positioning block includes a support surface and an arc surface. The arc surface is used to fit on the inner circular surface of the reference positioning ring, and the support surface is used to abut against the top surface of the reference positioning ring, which can play a good positioning role, ensure the close fit between the tooling and the reference positioning ring, prevent deviation during the detection process, and improve the detection reliability.

[0029] (5) Lightweight design. The detection base block is provided with a U-shaped weight reduction groove, and the disc body is provided with relief holes, reducing the overall weight of the tooling, facilitating handling and operation, and at the same time maintaining the structural strength.

[0030] (6) After using this tooling to detect the overlapping section of the casting flow splitting ring, it can clearly and efficiently display whether the overlapping section of the casting flow splitting ring is deformed, avoiding the stagnation of the process flow due to the inability to detect the surface of the overlapping section of the casting flow splitting ring, shortening the production cycle of the casting, saving resources and reducing costs.

Specifically, the detection groove 7 can be simultaneously stuck on the inner and outer profile surfaces of the shunt ring lapping section 104 to achieve an intuitive judgment of the deformation amount, solving the problem that the traditional scribing detection cannot accurately measure the local deformation.

[0052] Combined with Figure 3 As shown, two first detection stops 4a are provided on the detection base block 4, and a detection movable block 6 is installed at each position of the first detection stop 4a on the detection base block 4; one detection base block 4 and two detection movable blocks 6 form two detection grooves 7.

It reduces the repeated positioning time, improves the detection consistency, and avoids the errors caused by multiple adjustments of the tooling.

[0053] Combined with Figure 5 As shown, the positioning stop 3a includes a support surface 3b and an arc surface 3c; the arc surface 3c is used to closely abut against the inner circular surface of the reference positioning ring 105; the support surface 3b is used to abut against the top surface of the reference positioning ring 105.

[0055] Combined with Figure 3 As shown, a screw rod section 2a is provided at the top of the support column 2, the screw rod section 2a passes through the disc body 1 from bottom to top and is screwed with a locking nut 8; a gasket 9 is arranged between the locking nut 8 and the disc body 1. By adopting this structure, the support column 2 and the disc body 1 form a detachable structure.

[0056] Combined with Figure 3 As shown, the rib plate assembly 5 includes a T-shaped plate 5a, a connecting plate 5b and a connecting seat 5c; the T-shaped plate 5a is fixedly connected to the disc body 1 by bolts; the connecting seat 5c is installed on the top surface of the detection base block 4 by screws; the connecting plate 5b is installed on the top surface of the connecting seat 5c by screws; the T-shaped plate 5a is placed on the connecting plate 5b and bolted.

By providing the U-shaped weight-reducing groove 4c and the lightening holes 1a, the overall weight of the tooling can be reduced, which is convenient for the operator to carry and adjust, and improves the detection efficiency.

[0058] Combined with Figures 7 to 9 As shown, this embodiment also provides a method for detecting whether the profile of the lap section of the detection shunt ring is deformed. Using the above-mentioned tooling, it includes the following steps:

[0059] S1. Place the titanium alloy casting 100 of the casing type to be detected on the plane of the detection table;

[0060] S2. Vertically lower the tooling onto the titanium alloy casting 100 of the casing type, so that the positioning stop 3a on the positioning block 3 is stuck on the reference positioning ring 105; specifically, use the supporting surface 3b and the arc surface 3c of the positioning stop 3a to respectively fit the top surface and the inner circular surface of the reference positioning ring 105 to ensure that the tooling is strictly aligned with the casting reference, and improve the stability of the detection reference;

[0061] S3. Observe whether there is interference between the detection groove 7 on the tooling and the inner and outer profiles of the lap section 104 of the shunt ring during the lowering process of the tooling. If there is interference, it indicates that the lap section 104 of the shunt ring is deformed; if there is no interference, it indicates that the lap section 104 of the shunt ring is not deformed.

During detection, the two detection grooves 7 are used to detect two opposite lap sections 104 of the shunt ring on two adjacent support plates 103 at the same time, which improves the detection efficiency and is suitable for mass production environments.
