When in use, the device is placed in the specified position, and the supporting leg 1 plays a stable supporting role on the base 2, so that the device can be stably placed in the specified position for work, and then the clamping platform 11 is adjusted to the required height through the two first electric push rods 16. After adjusting the required height, the bearing seat to be processed is placed at the center of the clamping platform 11, and then the height of the first connecting blocks 6 on both sides is adjusted by the second electric push rods 14 on both sides so that the clamping plates 9 on both sides can clamp the height of the bearing seat. During the adjustment process of the first connecting blocks 6 on both sides, they will move along the positioning rods 4 on the fixed blocks 3 on both sides to prevent offset. After determining the position, the third electric push rods 8 on both sides will drive the clamping plates 9 on both sides to move relatively, clamp the bearing seat and fix it, which is convenient for processing the bearing seat.

[0029] The base 2 is provided with a rotating assembly for adjusting the angle of the bearing seat, and the rotating assembly includes a first motor 12, which is fixedly connected to the center of the lower end surface of the base 2, and the output end of the first motor 12 is fixedly connected to a first rotating shaft 13, which passes through the base 2, and the upper end surface of the first rotating shaft 13 is fixedly connected to a turntable 10, and the lower end surface of the turntable 10 is evenly and fixedly connected to four supporting wheels 17. When it is necessary to process the bearing seat at different horizontal positions, the first rotating shaft 13 can be driven to rotate by the first motor 12 on the base 2, and the first rotating shaft 13 drives the turntable 10 and the supporting wheels 17 to rotate, and stops after rotating to the required angle, so that different angles of the bearing seat can be processed.

[0030] The turntable 10 is provided with an adjustment component for adjusting the height of the bearing seat, and the adjustment component includes a first electric push rod 16. Two first electric push rods 16 are provided, and the two first electric push rods 16 are evenly fixedly connected to the upper end surface of the turntable 10 near the center on both sides. The output end of the first electric push rod 16 is fixedly connected to a clamping platform 11. When the bearing seat needs to be placed at different heights, the bearing seat is placed on the clamping platform 11. By adjusting the two first electric push rods 16 to raise or lower the clamping platform 11 to the required height, the bearing seat can be placed at different heights.

[0031] The clamping plates 9 on both sides are provided with anti-slip patterns on the side away from the third electric push rod 8. When the clamping plates 9 on both sides clamp the bearing seat, the anti-slip patterns on the clamping plates 9 will increase the friction between the clamping plates 9 and the bearing seat, which can effectively prevent the clamping plates 9 from slipping when clamping the bearing seat.

[0032] Example 2

[0033] The difference from Example 1 is that the base 2 is provided with chamfers at the end corners. When in use, the base 2 is provided with chamfers at the end corners, which can effectively prevent the staff from being scratched by the edges when operating the device, so that the staff can work in a safe environment.

[0034] The working principle of the utility model is as follows: when in use, the device is started, and the clamping platform 11 is first adjusted to the required height through the two first electric push rods 16. After adjusting the required height, the bearing seat to be processed is placed at the center of the clamping platform 11, and then the height of the first connecting blocks 6 on both sides is adjusted by the second electric push rods 14 on both sides, so that the clamping plates 9 on both sides can clamp the height of the bearing seat. During the adjustment process of the first connecting blocks 6 on both sides, they will move along the positioning rods 4 on the fixing blocks 3 on both sides to prevent deviation. After determining the position, the third electric push rods 8 on both sides will drive the clamping plates 9 on both sides to move relative to each other, clamp the bearing seat and fix it, which is convenient for processing the bearing seat. When there is a need to process the bearing seat at different horizontal positions, The first motor 12 on the base 2 can drive the first rotating shaft 13 to rotate, and the first rotating shaft 13 can drive the turntable 10 and the supporting wheel 17 to rotate, and stop after rotating to the required angle, and repeat the above steps to process the bearing seat. When it is necessary to process the bearing seat with different end faces, first put the bearing seat on the clamping table 11, and after being clamped and fixed by the clamping plates 9 on both sides, raise the second electric push rods 14 on both sides to make the bearing seat suspended in the air. At this time, start the second motors 5 on both sides, and the second motors 5 on both sides drive the second rotating shafts 15 on both sides to rotate, and the second rotating shafts 15 on both sides drive the second connecting blocks 7 and the clamping table 11 to rotate, and then turn the bearing seat to the flip side, so as to facilitate the processing of the other side of the bearing seat. It is highly practical and easy to use.
