[0021] See also Figure 1 and Figure 5 The surface of the gear 63 is in meshing state with the gear ring 62, and a scale groove 67 is provided on the surface of the support plate 64. By providing the scale groove 67, it is convenient for the staff to observe the height adjustment amount of the adjustment sleeve 68, so as to facilitate accurate control of the height adjustment. One side of the adjustment sleeve 68 is rotatably connected with a fastening bolt 69. By providing the fastening bolt 69, the adjustment sleeve 68 can be conveniently fixed to the surface of the support plate 64, so as to fix the position of the distance sensor 65. One end of the fastening bolt 69 passes through the adjustment sleeve 68 and is in close contact with the surface of the support plate 64.

[0022] See also Figure 1 The surface of the support plate 64 is fixedly connected with a limit baffle 66 located above the processing table 2. By setting the limit baffle 66, the rotation of the support plate 64 can be limited, thereby preventing it from shaking, so that the distance sensor 65 can remain stable during the rotation process, and the bottom of the limit baffle 66 is in sliding contact with the top of the processing table 2;

[0023] See also Figure 1 and Figure 4The bottom of the movable rod 46 is rotatably connected to the top of the processing table 2. The surfaces around the fixed cylinder 3 are penetrated with limited through holes 5. By setting the limited through holes 5, the movable rod 46 can be limited to prevent it from rotating with the threaded block 43, thereby improving the stability of the impeller blade fixation. The surface of the movable rod 46 penetrates the limited through hole 5 and is in sliding contact with the inner wall thereof.

[0024] See also Figure 4 The threaded rod 41 is rotatably connected to the center of the top of the processing table 2 through a bearing, a turntable 42 is fixedly connected to the top of the threaded rod 41, and a rotating handle is fixedly connected to the outer surface of the turntable 42;

By setting the rubber ball 44, the friction force with the inner ring of the impeller can be increased during the fixing process, so that the impeller can be stably detected.

[0026] When in use, the impeller is placed at the center of the top of the processing table 2 so that it is sleeved on the outside of the fixed cylinder 3, and then the threaded rod 41 is rotated by the turntable 42, and the threaded block 43 is driven downward by the action of the thread, so that it drives the support rod 45 to expand the movable rod 46, so that the rubber ball 44 can expand outward until the surface of the rubber ball 44 is in close contact with the inner wall of the impeller, so that the impeller can be positioned at the center of the top of the processing table 2, and then the stepper motor 61 is started, and the gear 63 is driven to rotate through its output shaft, and is meshed with the ring gear 62 through it. This drives the support plate 64 to rotate, and then the adjustment sleeve 68 and the distance sensor 65 make a circular rotation on the surface of the processing table 2, so that the distance sensor 65 detects the dimensions of the impeller blades all around. The distance data is converted into key dimension data according to the conversion algorithm. When it is necessary to detect the height of the distance sensor 65, loosen the fastening bolt 69, and then adjust the height of the adjustment sleeve 68 up and down through the scale groove 67. After the adjustment is complete, re-tighten the fastening bolt 69 to fix the adjustment sleeve 68 on the surface of the support plate 64, so that detection can be performed from different heights.

[0027] In summary: the online detection device for key dimensions in impeller blade grinding processing, through the cooperation of the processing table 2, the fixed cylinder 3, the positioning component 4 and the detection component 6, solves the problem that the current detection device usually manually positions the impeller first, and then manually operates the detection, which not only has poor work efficiency but also poor detection accuracy.
