[0023] A driven wheel 17 is arranged below the support table 3, a motor 16 is arranged on the workbench 1, a driving wheel 15 which is in engagement with the driven wheel 17 is sleeved on the output shaft of the motor 16, in this embodiment, the driving wheel 15 and the driven wheel 17 adopt bevel gears, a through hole is formed in the middle of the driven wheel 17, a cylinder one 8 is arranged below the driven wheel 17, a bottom plate 9 is arranged on the top end of the piston rod of the cylinder one 8, the bottom plate 9 is located between the two groups of fixed plates 5 through the through hole, a sliding block 20 is arranged on the upper side of the driven wheel 17 in a relative manner, and the lower ends of the two groups of fixed plates 5 are respectively connected to the driven wheel 17 in a sliding manner through the sliding block 20.

[0024] When the personnel need to turn the inner wall of the bearing, the two sets of fixed plates 5 are located on the outer wall of the bearing, the cylinder one 8 is in the state of not being stretched, the bottom plate 9 does not contact the lower side of the bearing, the electromagnetic suction block 13 is in the state of being electrified and being magnetically attracted to the magnetic suction block 14, the top rod 11 is in the fixed position, and the telescopic spring 18 is in the compressed state. At this time, the inner wall of the two sets of fixed plates 5 clamps the outer wall of the bearing, and the motor 16 is started. When the motor 16 is started, the driven wheel 17 is driven by the driving wheel 15 to rotate around the center axis of the driven wheel 17, so that the support table 3 and the two sets of fixed plates 5 rotate around the center axis of the driven wheel 17. At this time, the turning tool assembly 2 can move into the inner wall of the bearing to perform the turning operation.

[0025] When the turning of the inner wall of the bearing is completed and the turning of the outer wall of the bearing is needed, first, the turning tool assembly 2 is reset and does not contact the bearing. Then, the cylinder one 8 is controlled to be stretched by the control system, and the bottom plate 9 supports the bottom side of the bearing. Then, the electromagnetic suction block 13 is de-energized and is not magnetically attracted to the magnetic suction block 14. The telescopic spring 18 starts to reset, pulls the arc-shaped plate 6 to move horizontally away from the fixed plate 5, and simultaneously drives the wedge-shaped block one 7 and the wedge-shaped block two 21 to slide, so that the two sets of fixed plates 5 move away from each other and do not contact the outer wall of the bearing. Then, the cylinder one 8 continues to stretch, pushes the bearing out of the height range of the two sets of fixed plates 5, and stops. The cylinder two 10 starts to drive the top rod 11, the top rod 11 drives the arc-shaped plate 6 to move close to the fixed plate 5, the telescopic spring 18 starts to compress, the wedge-shaped block one 7 starts to slide with the wedge-shaped block two 21, and pushes the two sets of fixed plates 5 to move close to each other. The outer wall of the two sets of fixed plates 5 is located within the inner wall range of the bearing. The cylinder two 10 stops, the cylinder one 8 retracts, and the bearing moves downward until the two sets of fixed plates 5 pass through the inside of the bearing. The cylinder two 10 needs to be retracted, the telescopic spring 18 starts to reset, and indirectly makes the two sets of fixed plates 5 move away from each other. The outer wall of the fixed plate 5 is attached to the inner wall of the bearing. The electromagnetic suction block 13 starts to be electrified and is magnetically attracted to the magnetic suction block 14. The position of the fixed top rod 11 is fixed, the position of the fixed plate 5 is synchronously fixed, and then the motor 16 is started. The bearing can rotate at this time. The turning tool assembly 2 can move to the outer wall of the bearing to perform the turning operation, without the personnel manually disassembling, installing and changing the position of the bearing, thereby reducing the labor of the personnel.

[0026] The above embodiments are used to illustrate the present application, but are not used to limit the present application. Any simple transformation of the present application belongs to the protection range of the present application.
