when the bearing is disassembled, three supporting rods 909 are required to be arranged on the outer side surface of the bearing to clamp the bearing, hydraulic oil positioned in the oil storage tank 10 can flow into the second input port 902 through the oil delivery pipe 12 and enter the temporary storage tank 901 by opening the electromagnetic one-way valve positioned in the second input port 902, the electromagnetic one-way valve positioned in the second output port 903 is in a normally closed state at the moment, when the bearing is loosened, the electromagnetic one-way valve positioned in the second output port 903 can be opened, the hydraulic oil positioned in the temporary storage tank 901 can be led out through the second output port 903 at the moment, and the hydraulic oil can flow back into the oil storage tank 10 through the oil delivery pipe 12 to finish the circulation of the hydraulic oil and the resetting operation of the device;

when the bearing is clamped, hydraulic oil enters the interior of the temporary storage tank 901 through the second input port 902 and applies backward pressure to the second piston plate 904, at the moment, the return spring 9014 is compressed, the second piston plate 904 and the second piston rod 905 displace backward along with the second piston plate 904 and drive the movable seat 906 to displace backward, at the moment, as the movable seat 906 is connected with the support rod 909 and the support rod 909 is connected with the second fixed seat 908, the second fixed seat 908 can only slide relative to the guide rail 9013 under the drive of the sliding block 9010, namely when the movable seat 906 displaces backward, at the moment, one end of the first fixed seat 907 away from the movable seat 906 deflects toward the middle part, namely drives the three sliding blocks 9010 to approach towards the connecting seat 9012, at the moment, the three clamping plates 9011 approach relatively until three-point clamping is performed on the outer side surface of the bearing, and bearing fixing is completed, and conversely, the three clamping plates 9011 can be relatively far away from the loose bearing is realized;

when the bearing is disassembled, the outer side surface of the bearing is fixed in advance, at the moment, the upper and lower pressing operation plate 8013 is continuously needed to drive the first piston rod 808 to move up and down, the first piston plate 807 below and the connecting rod 805 are driven to reciprocate up and down, at the moment, the second mounting seat 804 reciprocates up and down, at the moment, the connecting rod 803 below the second mounting seat 804 deflects along with the second mounting seat, and synchronously drives the first mounting seat 802 to do circumferential movement, at the moment, the turntable 801 continuously rotates along with the rotating plate, and when the turntable 801 continuously rotates in the forward direction, the threaded rod 7 rotates along with the rotating plate, and under the cooperation of the internal threads of the threaded sleeve 6 and the threaded rod 7, the movable plate 5 is driven to move forward, the extension rod 3 and the pressing plate 4 are driven to move forward, and the pressure is applied to the main shaft inside the bearing, so that the bearing is forced to leave the main shaft, the bearing is detached from the main shaft, and is still clamped and fixed by the three temporary storage tanks 901 after the bearing is detached;

Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made therein without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
