Description

Technical Field

[0001] This utility model relates to a quick inspection tool for arc-shaped components of heavy-duty gas turbines, belonging to the field of gas turbine technology. Background Technology

[0002] Ceramic tiles (or heat insulation tiles) in heavy-duty gas turbines are key components of high-temperature parts, their core function being to isolate high-temperature combustion gases and protect the metal structure. As a typical component, the core quality indicators of ceramic tiles depend on the flatness of the arc-shaped mounting surface and the parallelism between the fixing rail and the arc-shaped surface. These geometric precisions directly affect the assembly sealing performance, thermal stress distribution, and long-term service reliability of the tiles.

[0003] In the current manufacturing process, the inspection of this part relies entirely on a coordinate measuring machine (CMM). Specifically: for the flatness of the arc mounting surface, the CMM needs to scan the surface point by point, fit a reference plane, and then calculate the deviation. For the parallelism between the fixed rail and the arc surface, the fixed rail trajectory and the axis of the arc surface need to be measured separately, and then the spatial parallelism error is calculated by software. This process has the following drawbacks: low efficiency: the CMM requires precise positioning and point-by-point data acquisition, and the inspection of a single part takes tens of minutes, which cannot meet the needs of mass production. Environmental limitations: the CMM requires a temperature-controlled and vibration-proof laboratory, making online inspection impossible in the workshop. High costs: the equipment purchase and maintenance costs are high, and the technical requirements for operators are stringent. Insufficient flexibility: it is difficult to adapt to the rapid changeover measurement needs of different tile models.

[0004] The limitations of existing solutions indicate that the industry urgently needs a fast, portable, and high-precision alternative detection method. Utility Model Content

[0007] Furthermore, the guide rail assembly includes linear guide rails fixed on the left and right sides of the test platform; a sliding block is connected to the linear guide rail; and a measuring component is connected to one side of the sliding block.

[0017] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. However, it should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit its scope.

[0018] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the invention.

[0019] like Figure 1 , Figure 2 and Figure 3As shown, a rapid inspection tool for arc-shaped components of heavy-duty gas turbines includes a test platform 1; the upper end of the test platform 1 is provided with an arc-shaped mating surface for receiving heavy-duty gas turbine ceramic tile 5, which is connected to the arc-shaped back surface of the heavy-duty gas turbine ceramic tile 5; guide rail assemblies are provided on the left and right sides of the test platform 1; a measuring component is provided on one side of the guide rail assembly.

[0020] In this embodiment, the guide rail assembly includes linear guide rails 2 fixed on the left and right sides of the test platform 1; a sliding block is connected to the linear guide rail 2; and a measuring component is connected to one side of the sliding block.

[0021] In this embodiment, the measuring component includes a magnetic base 3 connected to the guide rail assembly; the magnetic base 3 is connected to the dial indicator assembly 4 via a multi-section connecting arm; the dial indicator assembly 4 is used to quickly measure the flatness of the inner arc surface of the heavy-duty gas turbine ceramic tile 5 and the parallelism of the axis of the arc mounting surface of the heavy-duty gas turbine ceramic tile 5.

[0022] In this embodiment, the bottom of the test platform 1 is provided with a fixing slot, which is used to fix it to the operating table.

[0023] Reference Figure 4 The platform is designed with the same arc as the ceramic tile being tested. The heavy-duty gas turbine ceramic tile 5 is placed on the test platform 1. The dial indicator assembly 4 is used to contact the edge of the tile corner. At this time, the dial indicator reading is zeroed. The ceramic tile is pressed at the corner opposite the contact point of the dial indicator, and the change in the dial indicator reading is recorded. Next, the dial indicator is moved to the other corner of the tile, and the dial indicator is pressed at the corner opposite the contact point of the tile. The reading of the dial indicator 4 is recorded. The value of the reading determines the flatness of the tile's arc mounting surface. This method can quickly measure the flatness of the tile's arc surface and improve the speed of part inspection.

[0024] Reference Figure 5 Since the heavy-duty gas turbine ceramic tile 5 is mounted on the test platform 1 with its arc mounting surface, the dial indicator 4 is brought into contact with the fixed rail surface of the heavy-duty gas turbine ceramic tile 5. The reading of the dial indicator 4 is cleared to zero, and the slider of the linear guide rail is moved to move the dial indicator from one end to the other. The maximum reading of the dial indicator directly represents the parallelism between the fixed rail and the axis of the arc mounting surface of the heavy-duty gas turbine ceramic tile 5.

[0025] This tool can replace coordinate measuring machines (CMMs) for geometric measurement of ceramic tiles, greatly improving measurement efficiency, increasing the detection rate, and reducing production costs.

[0026] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions or improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
