[0026] Among them, by placing the rotor body 4 in the lifting ring block 6, and then the hydraulic rod 5 retracts downward to drive the lifting ring block 6 to move downward, the loading and unloading speed of objects during processing can be improved. The placed rotor body 4 contacts the two sets of rolling rollers 10 set on the supporting block 2 at both ends when following the downward movement, and is fitted to the two ends of the rotor body 4 through the limiting mechanism 8 for limiting and fixing, so as to avoid deviation during the rotation process and affect the processing quality. A rotatable circular rod is provided at one end of the limiting mechanism 8, which will not affect the rotation of the rotor body 4. Then the rotating component 7 is started to drive the two sets of rolling rollers 10 to rotate in the same direction, so that the forces on the two ends of the rotor body 4 during the rotation process can be uniform and consistent, and the grinding and polishing by the grinding processing block 3 set at the upper end of the processing table 1 can be more uniform and effective, so that the coaxiality of the rotor body 4 will not have a large error, and it is convenient to place and detect the high coaxiality of the rotor body 4, improve practical practicability, and facilitate daily use.

[0027] See attached Figure 1 -Attached Figure 2 As shown, the rotating assembly 7 includes a motor 701 and a driving rod 704. The motor 701 is arranged at one end of the outer surface of the supporting block 2. One end of the output shaft of the motor 701 is connected to a threaded rotating rod 702. The driving rod 704 is located between the two groups of rolling rollers 10, and the other end is arranged on one side of the outer surface of the supporting block 2.

The threaded rotating rod 702 and one end of the circular groove are both provided with the same through hole, and an insert rod 703 for fixing the threaded rotating rod 702 and the driving rod 704 is inserted in the through hole.

[0028] Among them, the threaded rotating rod 702 is driven to rotate by the motor 701. Since the threaded rotating rod 702 and the driving rod 704 are fixed by the insertion rod 703 inserted in the through hole opened at one end, the driving rod 704 will rotate along with the threaded rotating rod 702 during its operation, and the multiple groups of rubber rings 705 arranged at one end of the outer periphery of the driving rod 704 are used to increase its friction, so that the driving rod 704 can effectively drive the rolling rollers 10 at both ends to rotate in one direction, so that the rotational force on both ends of the rotor body 4 can be the same, thereby improving the processing quality and facilitating the placement and measurement when measuring the coaxiality of the rotor.

[0029] See attached Figure 3 As shown, the limiting mechanism 8 includes a movable shaft 801, which is rotatably installed at one end of the processing table 1, and one end of the movable shaft 801 is fixedly connected to a limiting plate 802. A circular rod that can follow the rotor body 4 is provided on the inner wall of the joint at one end of the limiting plate 802. A fixed plate 803 is fixedly installed on one end of the upper surface of the supporting block 2. A limiting rod 804 is disassembled and installed at one end of the fixed plate 803, and the other end of the limiting rod 804 is located on one side of the limiting plate 802.

[0030] It is worth noting that the rotor body 4 in this embodiment is a flywheel rotor body.

[0031] Among them, when the two ends of the rotor body 4 are placed in the rolling roller 10, the limit plate 802 connected to one end of the movable shaft 801 is turned over, so that one end of the limit plate 802 is in contact with the rotor body 4, and the contact surface of the limit plate 802 is semi-arc-shaped, which can be used to limit a variety of rotor bodies 4, improve the quality during processing, and make the processed rotor body 4 meet the required coaxiality requirements. Through the design of two sets of limit plates 802, the rotor body 4 will not shake or deviate during the grinding process.

[0032] Working principle: The telescopic end of the hydraulic rod 5 drives the lifting ring block 6 to rise, and the rotor body 4 to be processed is placed in the lifting ring block 6, and the rotor body 4 is sent to the rolling roller 10 through the lifting ring block 6, and then the limit plate 802 connected to the movable shaft 801 at one end is flipped, so that one end of the limit plate 802 is in contact with the rotor body 4, and the contact surface of the limit plate 802 is semi-arc-shaped, which can be used to limit a variety of rotor bodies 4, and the range of use is improved. The two sets of limit plates 802 are in opposite positions, respectively fixing the two ends of the rotor body 4, so that the rotor body 4 will not be offset during the processing. One end of the limit plate 802 is provided with a rotatable The circular rod is a circular rod, so when it fits one end of the rotor body 4, it will not affect the frequency of the rotor body 4 when it rotates.
