[0065] When the shaft hole of the rotor core is not located at the same horizontal axis, two balls 44 roll along the inner side wall of the rotor core at both ends of the fixed plate 42, the fixed rod 41 is made to slide on the sliding rod 51 through the fixed plate 42, two first springs 52 are deformed, and a resisting force is applied to one of the gravity sensors 64, so that the resisting rod 62 slides to the inside of the sleeve 61, the second spring 63 is deformed, the signal detected by the gravity sensor 64 changes, and thus the detection effect of the shaft hole of the rotor core is realized.

[0066] In the embodiment, a groove with an open top is formed on the bearing frame 1 below the rotating shaft 11, and a conveying mechanism 7 is installed on the bearing frame 1 in the groove, which is used for conveying the polished rotor core; the conveying mechanism 7 comprises two conveying rollers 71 which are both horizontally installed in the groove and rotate, the two conveying rollers 71 are drivingly connected through a conveying belt 72, and a third motor 73 is fixedly installed on the bearing frame 1 and used for driving one of the conveying rollers 71 to rotate.

[0067] By the design of the conveying mechanism 7, after the polished rotor core is rotated to one side of the polishing mechanism 3, the polished rotor core can be discharged onto the conveying belt 72 through the cooperation of the first electric push rod 15 and the second electric push rod 243, and the conveying belt 72 can be made to rotate around the two conveying rollers 71 through the third motor 73, so that the rotor core is conveyed, which facilitates the discharging operation of the polished rotor core and reduces the labor intensity of the workers.

[0068] The working principle and use process of the application are as follows:

[0069] When working:

[0070] The rotor core is sleeved on the outer side of the two resisting plates 23 installed on the mounting block 14 on one side of the rotating shaft 11, the second electric push rod 243 is controlled, the sliding block 241 is made to approach the connecting rod 22 in the mounting groove 211, the two connecting rods 22 are made to slide reversely on the fixed shell 21, and the two resisting plates 23 are both made to abut against the inner side wall of the shaft hole of the rotor core, so that the rotor core is fixed; the rotating shaft 11 is made to rotate on the bearing frame 1 through the electric motor 121, so that the rotor core is located below the polishing piece 33; the horizontal plate 313 is made to displace to the rotor core through the telescopic rod 312 through the third electric push rod 314, so that the polishing piece 33 is attached to the rotor core, the second electric motor 34 is controlled to be turned on, the polishing piece 33 is driven to rotate through the mounting shaft 32, and the first electric motor 142 is cooperated, so that the polishing effect on the surface of the rotor core is realized.

[0071] During the polishing process of the rotor core surface, the rotor core is fixed on the fixing mechanism 2 located in the opposite direction of the rotating shaft 11. After the polishing of the rotor core below the polishing mechanism 3 is completed, the rotating shaft 11 is rotated on the bearing frame 1 by the motor 121, so that the new rotor core to be polished is rotated to the polishing mechanism 3 below for polishing. At this time, the polished rotor core is rotated to one side of the polishing mechanism 3, the second electric push rod 243 is controlled to make the sliding block 241 move away from the connecting rod 22 in the installation slot 211, so as to cancel the fixing of the polished rotor core by the fixing mechanism 2 and perform the discharging operation. At the same time, the new rotor core to be polished can be fixed on the other fixing mechanism 2, and the same operation is repeated, so as to greatly save the waiting time during the loading and unloading of the rotor core during polishing, and improve the work efficiency.

[0072] During the polishing process of the rotor core surface, the rotor core is fixed on the fixing mechanism 2 located in the opposite direction of the rotating shaft 11. After the polishing of the rotor core below the polishing mechanism 3 is completed, the rotating shaft 11 is rotated on the bearing frame 1 by the motor 121, so that the new rotor core to be polished is rotated to the polishing mechanism 3 below for polishing. At this time, the polished rotor core is rotated to one side of the polishing mechanism 3, the second electric push rod 243 is controlled to make the sliding block 241 move away from the connecting rod 22 in the installation slot 211, so as to cancel the fixing of the polished rotor core by the fixing mechanism 2 and perform the discharging operation. At the same time, the new rotor core to be polished can be fixed on the other fixing mechanism 2, and the same operation is repeated, so as to greatly save the waiting time during the loading and unloading of the rotor core during polishing, and improve the work efficiency.

[0073] Moreover, when the shaft hole of the rotor core is not located on the same horizontal axis, the first motor 142 drives the rotor core to rotate, the two balls 44 roll along the inner side wall of the rotor core at both ends of the fixed plate 42, the fixed rod 41 slides on the sliding rod 51 through the fixed plate 42, the two first springs 52 are deformed, and one of the two first springs 52 applies a resistance force to the gravity sensor 64, so that the resistance rod 62 slides into the shell 61, the second spring 63 is deformed, and the detection signal of the gravity sensor 64 changes, so as to realize the detection effect of the shaft hole of the rotor core. When the detection signal of the gravity sensor 64 changes, the background control system receives the transmission signal of the gravity sensor 64, controls the buzzer to work, and warns the worker, reminding the worker that the polished rotor core has defects, so as to store the rotor core for further processing.

[0074] When the rotor core, which is polished and rotated to the side of the polishing mechanism 3, is discharged, the first electric push rod 15 is used to make the mounting block 14 slide on the sliding frame 13 towards the direction of the vertical plate 311, the second electric push rod 243 is controlled to make the sliding block 241 slide in the mounting groove 211 towards the direction of the connecting rod 22, so that the two connecting rods 22 slide reversely on the fixed shell 21 and approach each other, at this time, under the gravity of the rotor core, the rotor core contacts the abutting plate 23 located above and falls onto the conveying belt 72; after the rotor core falls onto the conveying belt 72, the first electric push rod 15 is used to make the mounting block 14 slide on the sliding frame 13 away from the vertical plate 311, so that the fixed shell 21 is located outside the rotor core, one of the conveying rollers 71 is rotated on the bearing frame 1 by the third motor 73, so that the conveying belt 72 rotates around the two conveying rollers 71, and the rotor core is conveyed, which facilitates the discharging operation of the polished rotor core and reduces the labor of the staff.
