[0045] The working principle and usage process of the present invention: As shown in the existing brake disc 2 Figure 5 There are casting characters 201 and mounting holes 202 on the end face of the brake disc 2. When clamping and adjusting the brake disc 2, the truss manipulator grabs the brake disc 2 from the previous process and puts it into this device. The driving cylinder 4 drives the first bracket 5 to move, so that the first pressing plate 6 on the first bracket 5 presses the end of the brake disc 2 on the second pressing plate 8. After the end pressing is in place, the rotating motor 101 drives the rotating shaft 104 to rotate through the transmission belt 103, so as to drive the brake disc 2 to rotate through the first pressing plate 6. The depth sensor 11 and the vision sensor 12 are started. The vision sensor 12 identifies the casting characters 201 and the non-casting characters 201 areas on the surface of the brake disc 2, and the depth sensor 11 identifies the height difference between the casting characters 201 and the end face. After the two sensors summarize the information, they transmit the signal to the rotating motor 101, and the rotating motor 101 drives the brake disc 2 to rotate to a specified angle, and then the manipulator grabs the brake disc 2 and puts it into the next process, which can well avoid the damage to the casting characters 201 of the brake disc 2 during the processing of the machining center and ensure the qualified rate of the product.
