[0019] The present invention will be further illustrated below with reference to the accompanying drawings and specific embodiments. It should be understood that these embodiments are only for illustrating the present invention and are not intended to limit the scope of the present invention. After reading the present invention, any modifications of the present invention in various equivalent forms by those skilled in the art will fall within the scope defined by the appended claims.
[0020] like Figures 1-4 As shown, this utility model provides a U-shaped groove thickness determination tooling for LNG marine thin-film insulation plates, including a tooling body 1. A first inner groove insertion part 2 and a second inner groove insertion part 3 are symmetrically arranged at both ends of the tooling body 1. The U-shaped groove 100 includes an outer groove 101 and an inner groove 102. The standard height of the inner groove 102 is 1.6mm. In this embodiment, the thickness of the first inner groove insertion part 2 and the second inner groove insertion part 3 is 1.5mm, slightly less than 1.6mm. A first thickness detection part 4 and a second thickness detection part 5 are also respectively arranged at both ends of the tooling body 1. The standard thickness of the insulation plate portion above the inner groove 102 is 4.70±0.5mm, so the distance between the first thickness detection part 4 and the first inner groove insertion part 2 is... The distance between the second thickness detection part 5 and the second inner groove insertion part 3 is the upper limit of the U-shaped groove thickness, which is 5.2 mm. The distance between the second thickness detection part 5 and the second inner groove insertion part 3 is the lower limit of the U-shaped groove thickness, which is 4.2 mm. The first inner groove insertion part 2, the second inner groove insertion part 3, the first thickness detection part 4 and the second thickness detection part 5 are all matched with the structure and shape of the outer groove 101 of the U-shaped groove 100. The bottom surfaces of the first inner groove insertion part 2 and the second inner groove insertion part 3 are all on the same horizontal plane as the bottom surface of the tooling body 1. The top surfaces of the first thickness detection part 4 and the second thickness detection part 5 are all on the same horizontal plane as the top surface of the tooling body 1. The first inner groove insertion part 2, the second inner groove insertion part 3, the first thickness detection part 4 and the second thickness detection part 5 are integrally formed with the tooling body 1.
[0021] In this embodiment, the above-mentioned tooling is used to detect the thickness of the U-groove of the LNG marine thin-film insulation plate. Specifically, it is used to determine whether the thickness of the insulation plate portion above the inner groove 102 is qualified. The specific operation method is as follows:
[0022] like Figures 5-7As shown, firstly, the first inner groove insertion part 2 and the first thickness detection part 4 of the tool body 1 are aligned with the U-shaped groove 100 and inserted. Specifically, the first inner groove insertion part 2 is inserted along the outer groove 101 into the inner groove 102. It is found that the first inner groove insertion part 2 can be smoothly inserted into the inner groove 102, and the second thickness detection part 5 can reach the top of the insulation plate without being blocked by the insulation plate part. This proves that the thickness of the insulation plate part is less than the upper limit value of 5.2mm.
[0023] Similarly, when the second inner groove insertion part 3 and the second thickness detection part 5 of the tool body 1 are aligned with the U-shaped groove 100 and inserted, it is found that the second thickness detection part 5 is blocked by the insulating plate part, which causes the second inner groove insertion part 3 to be unable to be inserted into the inner groove 102. This proves that the thickness of the insulating plate part is greater than the lower limit of 4.2mm.
[0024] In this way, the staff can directly determine that the thickness of the U-shaped groove is qualified. It should be noted that only when both of the above conditions are met can the thickness of the U-shaped groove be determined to be qualified. In other cases, the thickness of the U-shaped groove is determined to be unqualified.
[0025] As can be seen from the above operation process, the entire testing process is simple and quick, without the need to measure specific thickness values. This not only simplifies the operation but also enables comprehensive testing of whether the U-groove thickness is up to standard, eliminating blind spots in the testing. It can quickly, efficiently, and accurately determine whether the U-groove thickness is up to standard, greatly improving the testing efficiency of the U-groove thickness and ensuring the accuracy of the testing.
