[0033] In order to enable those skilled in the art of this technology to better understand the solution of this application, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of this application. Obviously, the described embodiments are only a part of the embodiments of this application, rather than all the embodiments. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of this application.

[0034] The embodiment of this application provides a flow distribution plate flatness and parallelism inspection tool, which can solve the problems of more operation steps, lower efficiency and easy occurrence of precision deviation in the prior art.

[0035] Refer to Figure 1 The overall structural schematic diagram of a flow distribution plate flatness and parallelism inspection tool in this application. A flow distribution plate flatness and parallelism inspection tool disclosed in this application includes a clamping and supporting component, a flatness detection component and a parallelism detection component. The clamping and supporting component includes a reference flat plate 1 and a V-shaped positioning block 2. During the detection process of the flow distribution plate product, the top surface of the reference flat plate 1 is used to place the product to be measured. The V-shaped positioning block 2 is slidably arranged on the reference flat plate 1. The groove part of the V-shaped positioning block 2 can clamp the product to be measured on the reference flat plate 1 to assist the inspector to fix the product to be measured; the flatness detection component includes a digital display micrometer 6. The digital display micrometer 6 is fixed on the reference flat plate 1, and the flatness detection head of the digital display micrometer 6 passes through the top surface of the reference flat plate 1, so that when the product to be measured is placed on the reference flat plate 1, it can press down the flatness probe head 7 of the digital display micrometer 6 by gravity, and then perform subsequent flatness detection; the parallelism detection component includes a lever dial indicator 3. The lever dial indicator 3 is arranged on the reference flat plate 1. When detecting the parallelism of the product to be measured, the probe head of the lever dial indicator 3 is in contact with the surface of the product to be measured, and the probe head of the lever dial indicator 3 is retracted by being pressed tightly by the surface of the product to be measured. The inspector holds the product to be measured by hand, so that the product to be measured rotates on the reference flat plate 1, and the probe head of the lever dial indicator 3 makes a relative circular motion on the surface of the product to be measured, and the parallelism data of the product to be measured can be measured. The operation is simple, and an inspection tool can perform two detections of parallelism and flatness, solving the problems of more operation steps, lower efficiency and easy occurrence of precision deviation.

[0036] In this embodiment, the reference flat plate 1 is made of steel structure material, specifically No. 45 steel, which has higher strength and good anti-deformation ability, can maintain the horizontal state of the surface of the reference flat plate 1 for a long time, and prolong the service life. In order to reduce the possibility of the V-shaped positioning block 2 slipping on the reference flat plate 1, the V-shaped positioning block 2 is adsorbed on the reference flat plate 1 by a magnet to reduce the influence of external force on the position of the V-shaped positioning block 2, so that the tester can move the V-shaped positioning block 2 and temporarily fix the V-shaped positioning block 2 stably on the reference flat plate 1 at the same time; a plurality of anti-slip grooves are also spaced along the length direction of the reference flat plate 1 on the surface of the reference flat plate 1, and the edges of the anti-slip grooves are all rounded, so as to reduce the possibility of the product to be tested slipping on the reference flat plate 1 and protect the surface of the product to be tested in contact with the reference flat plate 1, making it more convenient to use.

[0037] Refer to Figure 1 Refer to the overall structural schematic diagram of a flow distribution plate flatness and parallelism gauge in this application. The digital display micrometer 6 is specifically fixed at the bottom of the reference flat plate 1 by bolts, with a simple structure and convenient installation. The flatness probe 7 passes through from the bottom of the reference flat plate 1 and passes out from the top surface of the reference flat plate 1. In order to further facilitate the installation of the digital display micrometer 6, a support assembly is also provided below the reference flat plate 1 to stably support the reference flat plate 1, making it more convenient to use. The support assembly includes a plurality of support legs 5 fixed at the bottom of the reference flat plate 1. In this embodiment, specifically four support legs 5 are provided, and the tops of the four support legs 5 are all installed at the four corners of the bottom of the reference flat plate 1 by bolts to stably support the reference flat plate 1 and reduce the possibility of the reference flat plate 1 shaking during the detection process.

[0038] In this embodiment, the flatness probe 7 is specifically a ruby probe, which has higher strength. Since the flatness detection needs to be carried out by pressing, using a ruby probe with higher quality and strength can prolong the service life and reduce the maintenance and replacement frequency of the flatness probe 7.

[0039] When testing the flatness of the distribution plate, the inspector places the product to be tested flat on the reference plate 1. The product to be tested presses the flatness probe 7 to be flush with the reference plate 1 and activates the digital micrometer 6. The inspector uses the V-shaped positioning block 2 to clamp the upper part of the product to be tested, and pushes the product to be tested to a position convenient for the inspector to operate, always keeping the flatness probe 7 in a compressed state. After clearing the digital micrometer 6, the inspector holds the product to be tested by hand, and rotates the product to be tested with the help of the V-shaped positioning block 2, so that the product to be tested is close to the reference plane and rotates in a circle, and records the maximum and minimum runout values. After recording the data, slide the V-shaped positioning block 2 so that the product to be tested moves with the V-shaped positioning block 2 to change the contact position between the product to be tested and the flatness probe 7, and then hold the product to be tested by hand to rotate, and record the maximum and minimum runout values. The difference between the maximum and minimum values ​​in the final data is the flatness of the product to be tested.

[0040] The parallelism detection assembly also includes a micrometer angle adjustment frame, and the lever micrometer 3 is installed on the reference plate 1 through the micrometer angle adjustment frame, so that the detection personnel can adjust the position of the lever micrometer 3 abutting against the surface of the product to be tested during the detection process. In this embodiment, the micrometer angle adjustment frame is set as a universal joint support arm 4, one end of the universal joint support arm 4 is fixed to the reference plate 1 by bolts, and the lever micrometer 3 is fixed to the end of the universal joint support arm 4 away from the reference plate 1 by bolts. When performing parallelism detection, the detection personnel can directly bend the universal joint support arm 4 to change the position of the probe of the lever micrometer 3, and keep the probe of the lever micrometer 3 abutting against the upper surface of the product to be tested, so as to adapt to the products to be tested with different thicknesses.

[0041] When testing the parallelism of the distribution plate, the specific operating steps are the same as those for the flatness of the distribution plate. The difference is that the testing surface for the flatness of the distribution plate is the bottom surface where the product to be tested abuts against the reference plate 1, and the testing surface for the parallelism of the distribution plate is the top surface of the product to be tested on the reference plate 1. The parallelism and flatness tests of the distribution plate do not interfere with each other, and the two tests can be performed separately according to the needs of the testers. The testers can also be added to simultaneously record the data of the digital micrometer 6 and the lever micrometer 3 to simultaneously perform the two tests of the flatness and parallelism of the distribution plate.
