Description

Technical Field

[0001] The utility model belongs to the technical field of composite material forming, and particularly relates to a variable R-value comparison sample block laying combination tooling. Background Art

[0002] For the internal quality inspection requirements of composite materials, ultrasonic inspection has always been the most convenient and widely used non-destructive inspection method. Due to its high sensitivity, fast speed, low cost, and ability to locate and quantify defects, ultrasonic inspection is applied in various industries. However, since its display of defects is not intuitive enough and it is necessary to distinguish the types of defects according to the waveforms, it is often necessary to make corresponding comparison sample blocks to simulate the internal defect forms and patterns, so as to facilitate the inspectors to qualitatively determine the defects and finally form reasonable criteria.

[0003] According to relevant standards, ultrasonic inspection requires the manufacture of comparison sample blocks that are consistent with the materials, layup, process, structure, thickness, and surface state of the components. Therefore, the radius of curvature of the comparison sample blocks also needs to be consistent with the state of their corresponding components. In the existing production process, to ensure the consistency of the surface state and structure, the laying of comparison sample blocks often uses the laying tooling of the corresponding components for production.

[0004] The existing laying method of comparison sample blocks occupies the laying tooling of components and is difficult to lay and cure simultaneously with the components, which affects the production cycle and delivery schedule. If the corresponding laying tooling is not used, it is difficult to find the tooling with the corresponding structure and R value of the required comparison sample blocks at the production site. Moreover, investing in the laying tooling for a single project's new comparison sample blocks increases the project production cost and also affects the project cycle. Content of the Utility Model

[0005] To solve the deficiencies in the prior art, the utility model provides a variable R-value comparison sample block laying combination tooling, which can meet the manufacturing requirements of R-angle comparison sample blocks with different R values in different structural components, and can be laid and cured simultaneously with the components, reducing the production cost and shortening the production cycle.

[0020] The following further describes the present utility model with reference to the attached drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present utility model, and cannot be used to limit the protection scope of the present utility model.

[0021] Embodiment 1

[0022] As Figures 1 to 3 shown, a variable R-value comparison sample block paving combination tooling includes a base and an R-angle rotating shaft 21 installed on the base; there are multiple R-angle comparison sample block paving areas with different R values on the R-angle rotating shaft 21.

[0023] In the present utility model, the R-angle rotating shaft 21 is of a triangular prism structure, and connecting parts 22 for connecting with the base are respectively provided on two bottom surfaces of the triangular prism structure. There are three R-angle comparison sample block paving areas with different R values on the R-angle rotating shaft 21, and the three R-angle comparison sample block paving areas are respectively arranged on three mutually parallel sides of the triangular prism structure. The R values of the three R-angle comparison sample block paving areas are R5, R10, and R20 respectively.

[0024] In the present utility model, the base includes a base plate 11, support parts 12 and a limiting mechanism. There are two groups of support parts 12, and the structures of the two groups of support parts 12 are exactly the same. The support parts 12 are arranged on the base plate 11 and are used to cooperate with the connecting parts 22 to support the R-angle rotating shaft 21; the limiting mechanism is arranged on the support parts 12 and is used to keep the designated R-angle comparison sample block paving area in a set position.

[0025] In the present utility model, the connecting part 22 is of a cylindrical structure, and a U-shaped groove 13 matching the cylindrical structure is provided on the support part 12. The R-angle rotating shaft 21 with three R values (R5, R10, R20) is installed in the U-shaped groove 13 through the cylindrical connecting parts 22 protruding from both ends of the R-angle rotating shaft 21 of the triangular prism structure.

[0026] The limiting mechanism includes a limit block 14 and a driving unit for driving the limit block 14 to fit or separate from one side surface of the triangular prism structure.

[0027] An accommodation groove 15 for accommodating the limit block 14 is provided on the support part 12.

[0028] The driving unit includes a screw 16 (in the present utility model, an M10×50 hexagon socket head cap screw is used), and the screw 16 is threadedly connected to a threaded hole provided on the support portion 12. The screw 16 is connected to the limit block 14 and is used to drive the limit block 14 to fit or separate from one side surface of the triangular prism structure.

[0029] A spring 17 is provided between the limit block 14 and the support portion 12. The spring 17 is sleeved on the screw 16. The spring 17 is used to assist in pushing the limit block 14 and save the force when driving the limit block 14 to extend. At the same time, when the limit block 14 is being repaired, the spring 17 is also used to conveniently take out the limit block 14 from the accommodation groove 15.

[0030] When the R-angle rotating shaft 21 is placed in the U-shaped groove 13, by rotating the hexagon socket head cap screw, the spring 17 and the limit block 14 can contract. The limit block 14 separates from the corresponding side surface in the triangular prism structure and contracts into the accommodation groove 15. The R-angle rotating shaft 21 can rotate to realize the transformation of the paving area of the corresponding R-angle comparison sample block. When the paving area of the R-angle comparison sample block to be used is determined, rotate the screw in the reverse direction, the spring 17 and the limit block 14 extend, the limit block 14 extends into the bottom plane of the R-angle rotating shaft 21 of the triangular prism structure and fits with the corresponding side surface in the triangular prism structure, and the R-angle rotating shaft 21 is fixed. As Figure 2 shown, this paving tooling can be used.

[0031] Compared with the existing production method, the present utility model realizes that one tooling can meet the paving requirements of multiple comparison sample blocks with different R values, reduces the number of times of manufacturing the paving tooling for comparison sample blocks, and reduces the project loss cost. The present utility model does not occupy the actual parts of the paving tooling, speeds up the production progress, and at the same time realizes curing in the tank together with the parts, saves the curing cost, and improves the project efficiency.

[0032] On the basis of meeting the specification requirements, the present utility model can meet the paving use of multiple project R-angle comparison sample blocks through a tooling base and a rotating shaft with at least three different R values, reducing the cost of manufacturing the paving tooling.

[0033] Embodiment 2

[0034] The difference between this embodiment and Embodiment 1 is only that the specific structure of the driving unit in this embodiment is different. In this embodiment, the screw 16 passes through a through hole provided on the support portion 12 and is threadedly connected to the limit block 14. The screw 16 is used to drive the limit block 14 to fit or separate from one side surface of the triangular prism structure.

[0035] The above are only the preferred embodiments of the present utility model. It should be noted that for those of ordinary skill in the art, without departing from the technical principle of the present utility model, several improvements and modifications can be made, and these improvements and modifications should also be regarded as the protection scope of the present utility model.
