The upper end of the power telescopic rod B7 is fixed to the workbench 1, and a prism shaft 10 is slidably penetrated through the upper surface of the disc 4. A sleeve shaft 8 is fixed to the bottom surface of the disc 4. The sleeve shaft 8 is slidably sleeved on the outer surface of the prism shaft 10. An annular cavity 9 is provided inside the disc 4. A shaft cylinder 11 is slidably inserted into the bottom surface of the disc 4. The sleeve shaft 8 is located on the inner ring side of the shaft cylinder 11. The upper end of the shaft cylinder 11 is slidably inserted into the annular inner wall of the annular cavity 9. The prism shaft 10 can move up and down relative to the disc 4 and rotate synchronously with the disc 4.

[0026] The middle plate 2 is rotatably sleeved on the outer surface of the shaft cylinder 11. The lower end of the shaft cylinder 11 is in the shape of an annular disc. A plurality of evenly distributed ball bearings A18 are rotatably embedded on both the upper and lower surfaces of the annular disc at the lower end of the shaft cylinder 11. The ball bearings A18 are in rolling contact with the inner wall of the middle plate 2, and the ball bearings A18 reduce the resistance and wear when the shaft cylinder 11 rotates relative to the middle plate 2.

[0027] The lower plate 5 is rotatably sleeved on one end of the edge shaft 10 below the sleeve shaft 8. The lower end of the edge shaft 10 is in the shape of an annular disc. A plurality of evenly distributed ball bearings B19 are rotatably embedded on both the upper and lower surfaces of the annular disc at the lower end of the edge shaft 10. The ball bearings B19 are in rolling contact with the inner wall of the lower plate 5, and the ball bearings B19 reduce the resistance and wear when the edge shaft 10 rotates relative to the lower plate 5.

[0028] The bottom surface of the tooling table 1 is provided with a power structure 6. The power structure 6 is connected to one end of the sleeve shaft 8 below the shaft cylinder 11. The power structure 6 includes a multi-axis power box 61 and a plurality of vertical shafts 62. The front ends of the vertical shafts 62 are connected to the output ends of the multi-axis power box 61. The multi-axis power box 61 is fixed to the tooling table 1. One end of the sleeve shaft 8 below the shaft cylinder 11 is fixedly sleeved with a worm gear 64. One side of the worm gear 64 is engaged with a worm 63. The worm 63 is fixedly sleeved on the outer surface of the adjacent vertical shaft 62.

[0029] A plurality of round rods 12 are fixedly inserted on the upper surface of the disc 4. The upper ends of the round rods 12 are hinged with clamping claws 14. One side of the clamping claw 14 close to the axis of the disc 4 is hinged with a hinged rod 13. A stop block 17 is arranged on the side of the clamping claw 14 away from the axis of the disc 4. The bottom surface of the stop block 17 is fixed to the upper surface of the disc 4. The stop block 17 limits the maximum angle of outward rotation of the clamping claw 14.

When the edge shaft 10 moves upward, it can push the inner top block 16 away from the axis of the disc 4, so that the inner top block 16 is in contact and fixed with the inner wall of the inner hole of the cylinder block.

[0031] During use, after placing the cylinder block raw material on the disc 4, the inner top block 16 is located inside the inner hole of the cylinder block. The prism shaft 10 is pushed upward by the lower plate 5. The prism shaft 10 contacts the inclined surface of the inner top block 16, pushing the inner top block 16 away from the axis of the disc 4, so that the inner top block 16 contacts the inner wall of the inner hole of the cylinder block to fix the inner wall of the inner hole of the cylinder block. When controlling the intermediate plate 2 to drive the shaft cylinder 11 to move downward, the articulated rod 13 is pulled downward through the vertical rod 15, and the claw 14 is pulled to rotate to fixedly clamp the outer ring surface of the cylinder block. The multi-axis power box 61 drives a plurality of longitudinal shafts 62 to rotate synchronously. The longitudinal shafts 62 drive the sleeve shaft 8 to rotate through the engagement of the worm 63 and the worm wheel 64, so that a plurality of cylinder blocks on a plurality of discs 4 rotate simultaneously.
