[0018] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model.

[0019] The terms "left," "right," "front," "back," "up," and "down" used in the following description refer to the orientation from the perspective of the front view.

[0020] Example 1: In some embodiments, please refer to the accompanying drawings. Figures 1-7 An assembly inspection fixture includes a support frame 1, an adjustable angle telescopic support mechanism 2 mounted on the support frame 1, and a centering and moving mechanism 3 located below the support frame 1.

[0021] The adjustable angle telescopic support mechanism 2 includes a telescopic support assembly 21 and an angle adjustment assembly 22. The telescopic support assembly 21 is mounted on the support frame 1, and three telescopic support assemblies 21 are evenly distributed in a circular array on the support frame 1. The angle adjustment assembly 22 is mounted at the center of the support frame 1, and all telescopic support assemblies 21 are connected to the angle adjustment assembly 22. The angle adjustment assembly 22 is used to synchronously control the angle of all telescopic support assemblies 21.

[0022] In this invention, the telescopic support assembly 21 can extend and retract to the inner wall of the flow guide plate 4. Under the adjustment of the angle adjustment assembly 22, all the telescopic support assemblies 21 can reach the appropriate angle simultaneously, providing better support for the flow guide plate 4. The centering and moving mechanism 3 can make the flow guide plate 4 move synchronously, reducing the time required for hole alignment and inspection.

[0023] The telescopic support assembly 21 includes a mounting block 211, a rotating block 212, a rotating handle 213, a threaded rod 214, a threaded cylinder 215, a fixed sleeve 216, a first connecting block 217, and a support plate 218. The mounting block 211 is fixedly mounted on the support frame 1. The rotating block 212 is rotatably connected to the mounting block 211.

The threaded cylinder 215 is limited and slidably connected to the fixed sleeve 216.

[0024] In some embodiments, the hinge shaft is a damping shaft, which allows the support plate 218 to maintain its relative position with the threaded cylinder 215 when no force is applied. Under the action of the damping shaft, the support plate 218 can adapt to different curvatures, ultimately adapting to the curvature of the guide vane 4.

[0025] The angle adjustment assembly 22 includes a push cylinder 221, a sleeve 222, a first connecting rod 223, and a column 224. The column 224 is fixedly installed at the center of the upper platform of the support frame 1. The sleeve 222 is slidably connected to the column 224. The push cylinder 221 is fixedly installed on the upper platform of the support frame 1, and the output end of the push cylinder 221 is fixedly connected to the sleeve 222. One end of the first connecting rod 223 is hinged to the sleeve 222, and the other end of the first connecting rod 223 is hinged to the fixed sleeve 216.

[0026] In this utility model, the push cylinder 221 pushes the sleeve 222 to move vertically, and the sleeve 222 drives the first connecting rod 223 to move. With the cooperation of the rotating block 212 and the first connecting rod 223, the fixed sleeve 216 is raised, thereby raising the threaded cylinder 215 which is limited and slidably connected to the fixed sleeve 216, and thus raising the support plate 218 which is hinged to the threaded cylinder 215. When a suitable angle is reached, the rotating handle 213 is rotated to drive the threaded rod 214 to rotate. At the same time, with the cooperation of the fixed sleeve 216, the threaded cylinder 215 is extended and retracted. When the support plate 218 contacts the guide vane 4, the rotation stops.

[0027] The centering and moving mechanism 3 includes a fixed component 31 and a centering and moving component 32. The centering and moving component 32 is located directly below the center of the platform of the support frame 1 and is connected to the support frame 1. The fixed component 31 is installed on the centering and moving component 32, and there are three fixed components 31 evenly distributed in a circular array on the support frame 1.

[0028] The fixing component 31 includes an arc support frame 311, a main slide rail 312, a main slider 313, an auxiliary slide rail 314, and an auxiliary slider 315. The main slide rail 312 is fixedly installed on the ground. The main slider 313 is slidably connected to the main slide rail 312. The auxiliary slide rail 314 is symmetrically distributed at both ends of the main slide rail 312 and is fixedly installed on the ground. The auxiliary slider 315 is slidably connected to the auxiliary slide rail 314. The auxiliary slider 315 is used to assist in supporting the flow guide plate 4. The arc support frame 311 is fixedly connected to the main slider 313 and the auxiliary slider 315 respectively. The arc support frame 311 is provided with holes for bolting to the flow guide plate 4.

[0029] The centering and moving assembly 32 includes a drive motor 321, a turntable 322, a second connecting rod 323, and a push rod 324. The drive motor 321 is fixedly connected to the support frame 1, and the output end of the drive motor 321 is fixedly connected to the turntable 322. One end of the second connecting rod 323 is fixedly connected to the main slider 313, and the other end of the second connecting rod 323 is fixedly connected to the push rod 324. The turntable 322 is provided with a groove 325 for limiting and sliding with the push rod 324.

[0030] In this invention, the flow guide plate 4 is fixed by the arc support frame 311, and the turntable 322 is driven to rotate by the drive motor 321. The push rod 324 is limited to slide under the action of the slide groove 325, which in turn drives the second connecting rod 323 to move. The second connecting rod 323 pulls the main slider 313, and the arc support frame 311 is centered under the limit of the main slide rail 312. This achieves the consistency of the dimensions and hole positions of the flow guide plate 4 during the assembly process, eliminates unnecessary inspection steps, reduces the assembly cycle and improves operational reliability.
