[0022] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0023] Example 1:

[0024] Impeller height detection machine, such as Figures 1 to 2 As shown, it includes a frame 1, on which a base 2 for placing an impeller and a stroke-readable cylinder 3 are provided, with the base 2 and the stroke-readable cylinder 3 being arranged opposite to each other.

[0025] The output end of the stroke-readable cylinder 3 is equipped with a pressure block 4. The stroke-readable cylinder 3 is used to drive the pressure block 4 to move closer to or away from the base 2. By extending or retracting the output end of the stroke-readable cylinder 3, the pressure block 4 can move closer to or away from the base 2.

[0026] A control module 5 is installed on the frame 1. The control module 5 is electrically connected to the stroke readable cylinder 3. A display unit 6 is installed on the control module 5. When the stroke readable cylinder 3 drives the pressure block 4 to move and press the impeller onto the base 2, the stroke readable cylinder 3 transmits the stroke value to the control module 5. The control module 5 calculates the difference between the preset initial position height and the stroke value of the stroke readable cylinder 3 and displays it on the display unit 6.

[0027] When detecting the height of the impeller, the user only needs to place the impeller on the base 2 and then activate the stroke readable cylinder 3. The output end of the stroke readable cylinder 3 extends and drives the pressure block 4 to approach the base 2 until the pressure block 4 presses the impeller onto the base 2. At this time, the stroke readable cylinder 3 transmits the stroke value to the control module 5. The control module 5 calculates the difference between the preset initial position height and the stroke value of the stroke readable cylinder 3 and displays it on the display unit 6, thereby detecting the height of the impeller.

[0028] Users can directly read the impeller height from the display unit 6, which not only ensures measurement accuracy but also effectively reduces the complexity of operation, making it convenient for users to read the height and avoiding errors caused by manual observation of the scale.

[0029] The pressure block 4 is set on the mounting plate 7. The frame 1 is provided with a guide rod 8, and a guide sleeve 9 is slidably set on the guide rod 8. The guide sleeve 9 is connected to the mounting plate 7. When the output end of the stroke readable cylinder 3 extends or retracts, the output end of the stroke readable cylinder 3 drives the pressure block 4 to move. The pressure block 4 drives the mounting plate 7 and the guide sleeve 9 to move along the length direction of the guide rod 8. It should be noted that the mounting plate 7 is guided by the cooperation of the guide rod 8 and the guide sleeve 9, thereby ensuring the stability of the mounting plate 7 and the pressure plate when they move.

[0030] The base 2 is provided with a positioning groove 10 for positioning the impeller. The positioning groove 10 is adapted to the impeller. A through hole 11 is opened in the positioning groove 10. The positioning groove 10 restricts the impeller, thereby ensuring the stability of the impeller during the testing process. The through hole 11 is used to avoid the impeller.

[0031] The bottom of the positioning groove 10 is provided with an anti-wear layer 13 to reduce wear when the impeller comes into contact with the positioning groove 10.

[0032] The frame 1 has a mounting base 12, and the base 2 is connected to the mounting base 12 by bolts. This not only ensures the stable connection between the base 2 and the mounting base 12, but also makes the base 2 detachable. Therefore, bases of different sizes can be replaced according to the size of the impeller, making it more widely applicable.

[0033] Example 2:

[0034] The difference between Example 2 and Example 1 is that, as Figures 3 to 4 As shown, the mounting base 12 is provided with a clamping assembly 14 for holding the impeller. The clamping assembly 14 includes two fixing plates 141, two clamping plates 142, and two springs 143. The two fixing plates 141 are respectively disposed on both sides of the mounting base 12. Each fixing plate 141 is provided with a corresponding guide rod 16. Each clamping plate 142 is provided with a corresponding guide sleeve 15. The two springs 143 are respectively sleeved on the corresponding guide rods 16. The two guide rods 16 are slidably engaged with the corresponding guide sleeves 15. One end of the spring 143 is connected to the fixing plate 141, and the other end of the spring 143 is connected to the end of the guide sleeve 15. By using the two clamping plates 142 to clamp the impeller, the stability of the impeller during the height measurement process can be ensured.

[0035] Further, the two clamping plates 142 are provided with V-shaped grooves 17, which are suitable for impellers of different sizes, and the V-shaped grooves 17 are provided with wear-resistant pads 18 made of rubber, so as to avoid damage to the impeller when the two clamping plates 142 clamp the impeller.

[0036] When clamping, the two clamping plates 142 are pushed by external force, the guide sleeve 15 moves along the length direction of the guide rod 16, the guide sleeve 15 is pressed by the fixed plate 141 to extrude the spring 143, the two clamping plates 142 are away from each other, then the impeller is placed on the base 2, finally the external force applied on the two clamping plates 142 is removed, the guide sleeve 15 and the clamping plates 142 are pushed to move under the elastic restoring force of the spring 143, so that the two clamping plates 142 are close to each other and clamp the impeller.

[0037] The specific embodiments described herein are merely illustrative of the spirit of the present application; those skilled in the art to which the present application belongs can make various modifications or supplements to the described specific embodiments or replace them with similar ways, but will not deviate from the spirit of the present application or exceed the scope defined by the appended claims.
