[0028] In a preferred solution, a reducer 9 is provided at the end of the housing 7 , the output shaft of the servo motor 8 is connected to the input end of the reducer 9 , and the output end of the reducer 9 extends into the housing 7 .

[0029] In a preferred embodiment, a slider 11 is provided in the housing 7 , a screw rod 12 is passed through the slider 11 , the screw rod 12 and the slider 11 are threadedly matched, and one end of the screw rod 12 is connected to the output end of the reducer 9 through a coupling 13 .

[0030] In a preferred solution, a screw support plate 14 is fixedly provided in the housing 7 , one end of the screw 12 is connected to the inner wall of the end of the housing 7 , and the end close to the servo motor 8 is arranged through the screw support plate 14 .

[0031] In a preferred solution, side wing plates 15 are provided on both sides of the portion of the centering column top block 10 located at the shell 7 , and two groups of guide rods 16 are provided in the shell 7 . The two groups of guide rods 16 are perpendicular to the side wing plates 15 and pass through the two side wing plates 15 respectively.

[0032] In a preferred solution, the contact surface between the sliding block 11 and the top block 10 of the centering column is an inclined top surface 20 , and the contact surface between the top block 10 of the centering column and the sliding block 11 is an inclined bottom groove 19 .

[0034] The present invention discloses a block-supported guide bearing center positioning training system. In teaching and training, when the center adjustment of the centering column 2 (i.e., the simulated guide bearing) is required:

[0035] The device is powered on by means of the control button 6, and the center adjustment amount (horizontal and vertical coordinate values) of the centering column 2 is input through the touch screen 5. The control module in the electrical box 4 controls the corresponding actions of the four centering column moving mechanisms 3 to adjust the supporting force of the centering column 2 in the horizontal direction, and finally achieves the purpose of adjusting the center position of the centering column 2.

[0036] During the above-mentioned adjustment process, the servo motor 8 receives the instruction and rotates forward or reversely, driving the screw 12 to rotate, thereby realizing the movement of the slider 11 in the vertical direction. Since the slider 11 and the centering column top block 10 rely on the inclined bottom groove 19 and the inclined top surface 20 to cooperate, during the movement of the slider 11, the centering column top block 10 is limited by the guide rod 16. At this time, the centering column top block 10 will extend or contract in the horizontal direction, thereby completing the purpose of adjusting the center of the centering column 2.

[0037] In the above process, the first limit sensor 17 and the second limit sensor 18 sense the distance between themselves and the approaching guide rod 16. When approaching the guide rod 16, the sensor transmits a signal to the control module, and the control module controls the servo motor to stop running, thereby achieving the maximum telescopic stroke of the centering column top block 10.
