A telescopic cylinder 6 is provided at the bottom center of the top plate 3, and a fixed plate 7 is provided at the bottom of the telescopic cylinder 6.

[0025] A telescopic rod 11 is provided at the center of the inner bottom of the fixed frame 5, a telescopic rod top plate 13 is provided at the top of the telescopic rod 11, a fixing block 14 is provided at the center of the top of the telescopic rod top plate 13, a fixing groove 20 is provided at the center of the bottom of the replaceable ring 15, the surface of the fixing groove 20 is provided with an external thread, the surface of the fixing block 14 is provided with an internal thread, and the fixing groove 20 is connected to the fixing block 14 by a thread;

[0026] A fixing through hole 17 is formed through the center of the top and bottom of the brake disc 16 , and a replaceable ring sleeve 15 is provided at the fixing through hole 17 .

[0027] Furthermore, the shape of the fixing frame 5 is a truncated cone with an open top, the outer surface of the brake disc 16 contacts the inner surface of the fixing frame 5 , and the bottom of the fixing plate 7 contacts the top of the brake disc 16 .

[0028] Specifically, such as Figure 1 As shown, the fixing frame 5 is designed into the shape shown in the figure, and the diameters of the brake disc 16 of various sizes are located at different horizontal planes, which facilitates the upper and lower clamping and fixing of the brake disc 16.

[0029] Furthermore, a fixing extension plate 18 is provided on the top of the fixing through hole 17 , and an outer surface of the fixing extension plate 18 is connected to a surface of the fixing through hole 17 .

[0036] Then start the telescopic cylinder 6 to move the fixed plate 7 downward, and the fixed plate 7 will act on the brake disc 16, so that the brake disc 16 and the replaceable ring sleeve 15 assembly will move downward. When the outer surface of the brake disc 16 of the brake disc 16 and the replaceable ring sleeve 15 assembly contacts the inside of the fixed frame 5, the dynamic balancing test system is started to complete the detection of the brake disc 16; after completing the detection of one brake disc 16, the replaceable ring sleeve 15 can be replaced according to the model of the brake disc 16 to be tested.

[0037] Among them, after the dynamic balancing test system is started, the following is an existing mature technology, and its internal specific structure and working principle will not be described in detail here.
