Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] Example: Figures 1-4 As shown, the utility model provides a technical solution, including a main support frame 1, a secondary support frame 2 is fixedly connected to the outer wall of one side of the main support frame 1, a movable plate 3 is provided on the top surface of the secondary support frame 2, a docking mechanism 4 is provided on the secondary support frame 2, and a fine-tuning component 5 is provided on the movable plate 3;

[0023] The docking mechanism 4 includes a mounting plate 41 and two parallel guide rods 46. The mounting plate 41 is fixedly connected to the inner walls at both ends of one side of the auxiliary support frame 2. The outer wall of one side of the mounting plate 41 is fixedly connected to a servo motor 42. The output end of the servo motor 42 is coaxially fixedly connected to a first screw 43. The outer wall of the first screw 43 on the side away from the servo motor 42 rotates through the outer wall of one side of the mounting plate 41 and is rotatably connected to a fixed plate 44. The outer surface of the first screw 43 is threadedly connected to a threaded sleeve 45. The two guide rods 46 are both fixedly connected to the inner wall of one side of the auxiliary support frame 2. The outer surface of the guide rod 46 is slidingly sleeved with a sliding sleeve 47. The top surfaces of the two sliding sleeves 47 are fixedly connected to the bottom surface of the movable plate 3.

[0024] Further as Figure 1 、 Figure 2 、 Figure 3 and Figure 4As shown, it is worth mentioning that the fine-tuning component 5 includes a movable groove 51 and two parallel sliding rods 55. The movable groove 51 is opened through the top surface of the movable plate 3. The two sliding rods 55 are fixedly connected between the two end walls inside the movable groove 51. A second screw 52 is rotatably connected between the two end walls on one side of the movable groove 51. The outer surface of the second screw 52 is threadedly connected to a moving block 53. The outer wall of one end of the second screw 52 rotates through the outer wall of one end of the movable plate 3 and is coaxially fixedly connected to a turning handle 54.

[0025] Further as Figure 1 、 Figure 3 and Figure 4 As shown, it is worth mentioning in detail that the outer surfaces of the two sliding rods 55 are slidably connected to the same placement plate 6, and the fan body 7 is provided on the placement plate 6.

[0026] Further as Figure 1 and Figure 4 As shown, it is worth mentioning that four support rods 8 are fixedly connected to the top surface of the main support frame 1, the same test air duct 9 is fixedly connected between the four support rods 8, and a controller 10 is installed at one end of the top surface of the main support frame 1.

[0027] Further as Figure 1 、 Figure 2 and Figure 4 As shown, it is worth mentioning that the top surface of the auxiliary support frame 2 is in contact with the bottom surface of the movable plate 3, which has a supporting effect on the movable plate 3. The top surface of the fixed plate 44 is fixedly connected to the inner wall of the top surface of one side of the main support frame 1, and the top surface of the threaded sleeve 45 is fixedly connected to the bottom surface of the movable plate 3. The threaded sleeve 45 is driven to move by the rotation of the first screw 43, thereby driving the movable plate 3 to move on the top surface of the auxiliary support frame 2.

[0028] Further as Figure 1 、 Figure 2 、 Figure 3 and Figure 4 As shown, it is worth mentioning that the outer walls of the two guide rods 46 on one side away from the auxiliary support frame 2 are fixedly connected to the outer wall of one side of the main support frame 1. Through the cooperation of the guide rod 46 and the sliding sleeve 47, the movable plate 3 is more stable when moving. The outer wall of one side of the movable block 53 is fixedly connected to the outer wall of one side of the placement plate 6. The movable block 53 is driven to move by the second screw 52, ​​so that the placement plate 6 drives the fan body 7 to be fine-tuned, which facilitates the docking of the fan body 7 with the test duct 9. The output end of the fan body 7 is connected to the input end of the test duct 9 through a flange.

[0029] In summary: When the detection device is in use, the fan body 7 to be tested is first placed on the top surface of the placement plate 6, and then the handle 54 is rotated to drive the second screw 52 to rotate. Under the action of the thread, the rotating second screw 52 drives the moving block 53 to move. Through the sliding cooperation between the slide rod 55 and the placement plate 6, the moving block 53 drives the placement plate 6 to perform fine-tuning movement on the slide rod 55, thereby achieving fine-tuning of the position of the fan body 7, improving the accuracy of the docking of the fan body 7 and the test wind tube 9, and is simple to operate, effectively avoiding the problem of difficulty in fine-tuning when the fan is connected to the detection device.

[0030] When the placement plate 6 drives the fan body 7 to move until the output end of the fan body 7 and the input end of the test air duct 9 are on the same axis, the servo motor 42 is turned on to drive the first screw 43 to rotate. Under the action of the thread, the rotating first screw 43 drives the threaded sleeve 45 to move. Under the sliding cooperation of the sliding sleeve 47 and the guide rod 46, the threaded sleeve 45 drives the movable plate 3 to move toward the input end of the test air duct 9. As the movable plate 3 drives the placement plate 6 to move gradually, the output end of the fan body 7 gradually fits with the input end of the test air duct 9. After the fan body 7 and the test air duct 9 are connected by the flange, the fan body 7 is inspected, which effectively avoids the problem that the fan is large in size and is more difficult to connect with the detection device.

[0031] The servo motor 42 can be purchased on the market. The servo motor 42 is equipped with a power supply, which is a mature technology in this field and has been fully disclosed, so it will not be repeated in the specification.

Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be encompassed within the present invention.
