[0026] As shown in Figure 3 , it further comprises a reinforcing assembly, the reinforcing assembly comprises an electromagnet 6, a magnetic plate 61 and a rubber block 7, the electromagnet 6 is fixedly connected in the cavity of operating platform 2, the rubber block 7 is slidably connected in the cavity of operating platform 2, the magnetic plate 61 is fixedly connected to the bottom of rubber block 7, the magnetic plate 61 is magnetically attracted to the electromagnet 6, the electromagnet 6 is electrically connected with motor 3, the rubber block 7 is extruded with four resistance plates 4.

[0027] As shown in Figure 4 , it further comprises a jacking assembly, the jacking assembly comprises an electric push rod 8 and a top plate 9, the left and right sides of operating platform 2 lower portion are installed with electric push rod 8, the telescopic part of two electric push rods 8 is fixedly connected with top plate 9, two top plates 9 are slidably connected with operating platform 2.

[0028] Initially, the connecting frames 11 of the left and right parts are in positions away from each other, and the electromagnet 6 is attracted to the magnetic plate 61. When the device is used, the staff first places the rotor core to be trimmed in the center of the operation table 2. At this time, the inner wall of the rotor core will press the stop plate 4 to move inward, and the first spring 5 will be deformed. Under the elastic force of the first spring 5, the four stop plates 4 will be respectively stopped against the front, rear, left and right four sides of the inner wall of the rotor core. Then, the handle 13 is turned according to the trimming needs. For example, if the outer side of the rotor core needs to be polished, the handle 13 is held and turned clockwise, so as to drive the concave disc 131, the clamping rod 14, the sliding frame 142, the cutter 15 and the polishing rod 16 to rotate. The rotating concave disc 131 will press the inclined block 12 to move outward to exit from the wedge-shaped clamping hole, and the elastic rope 121 will be deformed.

[0029] When the polishing rod 16 rotates to the side close to the rotor core, the rotation of the handle 13 is stopped. At this time, the concave disc 131 no longer presses the inclined block 12, and under the elastic force of the elastic rope 121, the inclined block 12 slides inward to be inserted into the wedge-shaped clamping hole of the concave disc 131 for clamping. Similarly, when the outer side of the rotor core needs to be deburred, the handle 13 is turned to make the deburring cutter 15 also rotate to the side close to the rotor core.

[0030] Then, the two clamping blocks 101 are pulled out forward, and the connecting frames 11 of the left and right parts are moved inward to close, so that the two cutters 15 or polishing rods 16 close to the rotor core are attached to the outer side of the rotor core, and the two clamping blocks 101 are inserted back to the original position. Then, the motor 3 drives the operation table 2 to rotate counterclockwise, thereby driving the rotor core to rotate. The cutter 15 or the polishing rod 16 will trim the rotating rotor core, and the adjacent second spring 141 will be slightly deformed. At the same time, the motor 3 also controls the magnetic field of the electromagnet 6 to change. The electromagnet 6 will repel the magnetic plate 61. Under the action of the magnetic force, the magnetic plate 61 will drive the rubber block 7 to move upward. The upward moving rubber block 7 will press the four stop plates 4, so that the four stop plates 4 always keep abutting against the inner wall of the rotor core. During the entire trimming process, the rotor core always stays in the central position of the operation table 2, and the vertical center line of the rotor core will not be deviated.

[0031] When the trimming is completed, the motor 3 is controlled to stop driving the operation table 2 to rotate. The magnetic field of the electromagnet 6 is restored to the initial state immediately. The electromagnet 6 will attract the magnetic plate 61, so that the magnetic plate 61 drives the rubber block 7 to move downward and reset. The rubber block 7 no longer abuts against the stop plate 4. Then, the electric push rod 8 is controlled to drive the top plate 9 to move upward. The upward moving top plate 9 will push the trimmed rotor core upward. At this time, the staff can take the rotor core off the operation table 2 by using the upward pushing force. When the inner wall of the rotor core is separated from the stop plate 4, the stop plate 4 will move outward and reset under the elastic force of the first spring 5.

[0032] When the effect of the tool 15 or polishing rod 16 decreases with the increase of usage time and needs to be replaced, the tool 15 or polishing rod 16 to be replaced can be held and pulled upward, thereby driving the adjacent clamping rod 14 to move upward until it is removed from the turning handle 13, and a new tool 15 or polishing rod 16 can be taken and put back in place. In summary, the support plate 4, the first spring 5, and the reinforcement assembly can be used to fix rotor cores of different sizes. Secondly, the slide rail 10, the clamping block 101, and the connecting frame 11 can be used to trim rotor cores of different sizes. Then, the turning handle 13, the concave plate 131, the bevel block 12, and the clamping rod 14 can be used to replace the tool 15 or the polishing rod 16 as needed. The entire device can meet the needs of castings of different sizes and shapes, and no frequent adjustments are required during use, which increases the applicability of the device.

[0033] Example 2

[0034] On the basis of Example 1, Figure 8 As shown, a fan 17 is also included. The fan 17 is installed on the rear side of the mounting plate 1 and is used to blow away grinding debris.

[0035] When the rotor core is being trimmed, the fan 17 can be controlled to blow air toward the rotor core. The wind can blow away all the debris generated during the trimming, preventing it from sticking to the rotor core and affecting its smoothness, thereby improving the trimming effect.

Personnel familiar with the art may make various modifications or changes to the above embodiments without departing from the utility model concept of the present invention.
