[0018] According to Figure 1 、 2 As shown in FIGS. 1, 2, and 3, this embodiment proposes a detection device for centrifugal pump production that is convenient for adjustment, including a bottom plate 1. Above the bottom plate 1, a fixing mechanism is provided. Inside the fixing mechanism, a fixed frame 2 is installed. At the top of the fixed frame 2, a centrifugal pump body 3 is installed. On one side above the bottom plate 1, a moving mechanism is provided, and a dial indicator 4 is movably installed on the moving mechanism.

[0019] The fixing mechanism includes a mounting frame 11, a threaded hole 12, a screw 13, a pressing plate 14, a runner 15, and a limiting structure. The mounting frame 11 is installed above the bottom plate 1. A threaded hole 12 is penetrated through the inside of the mounting frame 11. A screw 13 is penetrated through the threaded hole 12. At the bottom end of the screw 13, a pressing plate 14 is rotatably installed. At the top end of the screw 13, a runner 15 is installed. There are two mounting frames 11 above the bottom plate 1, and the two mounting frames 11 are symmetrically distributed about the central axis of the bottom plate 1. During use, the fixed frame 2 and the centrifugal pump body 3 are taken out, the fixed frame 2 is placed inside the mounting frame 11, and then the runner 15 is rotated to drive the screw 13 to rotate. Since a threaded connection is formed between the threaded hole 12 and the screw 13, the screw 13 moves inside the threaded hole 12. Then, under the limitation of the limiting groove 16 and the limiting block 17, the screw 13 drives the pressing plate 14 to move, and the pressing plate 14 is used to press the fixed frame 2, so as to fix the centrifugal pump body 3, making the centrifugal pump body 3 more stable and not prone to shaking during detection, thereby greatly improving the accuracy of the device during detection.

[0020] The limiting structure includes a limiting groove 16 and a limiting block 17. The limiting groove 16 is opened on one side inside the mounting frame 11. A limiting block 17 is arranged inside the limiting groove 16. One end of the limiting block 17 is connected to one side of the pressing plate 14. The cross-section of the limiting groove 16 is larger than that of the limiting block 17. A sliding structure is formed between the limiting groove 16 and the limiting block 17. During use, by the mutual cooperation between the limiting groove 16 and the limiting block 17, the movement of the pressing plate 14 can be limited, making the movement of the pressing plate 14 more stable.

[0021] The moving mechanism includes a mounting cavity 5, a servo motor 6, a threaded rod 7, a threaded sleeve 8, a first electric telescopic rod 9 and a second electric telescopic rod 10. The mounting cavity 5 is installed at the top end of the bottom plate 1. A servo motor 6 is installed at one end of the mounting cavity 5. A threaded rod 7 is installed inside the mounting cavity 5. The output end of the servo motor 6 is connected to one end of the threaded rod 7. A threaded sleeve 8 is arranged on the outer side wall of the threaded rod 7.

The bottom end of the second electric telescopic rod 10 is connected to the top end of the dial indicator 4. During use, start the servo motor 6 to drive the threaded rod 7 to rotate, and then drive the threaded sleeve 8 to move. At this time, start the first electric telescopic rod 9 and the second electric telescopic rod 10 to adjust the dial indicator 4 to an appropriate position, so that the probe of the dial indicator 4 is aligned with the central axis of the centrifugal pump body 3, which can drive the dial indicator 4 to move up, down, left and right, and the dial indicator 4 can be adjusted to an appropriate position according to different centrifugal pumps, thus greatly improving the versatility of the device during use.

[0022] A groove body is opened inside the mounting cavity 5, and the groove body can guide the movement of the threaded sleeve 8. The design of the groove body makes the movement of the threaded sleeve 8 more stable.

[0023] Working principle: First, the staff takes out the fixing frame 2 and the centrifugal pump body 3, places the fixing frame 2 inside the mounting frame 11, and then rotates the rotating wheel 15 to drive the screw rod 13 to rotate. Since a threaded connection is formed between the threaded hole 12 and the screw rod 13, the screw rod 13 moves inside the threaded hole 12. Then, under the limitation of the limiting groove 16 and the limiting block 17, the screw rod 13 drives the pressing plate 14 to move, and the pressing plate 14 is used to press the fixing frame 2, so as to fix the centrifugal pump body 3. Then start the servo motor 6 to drive the threaded rod 7 to rotate, and then drive the threaded sleeve 8 to move. At this time, start the first electric telescopic rod 9 and the second electric telescopic rod 10 to adjust the dial indicator 4 to an appropriate position, so that the probe of the dial indicator 4 is aligned with the central axis of the centrifugal pump body 3, and the centrifugal pump body 3 is detected by the dial indicator 4.
