[0027] Specifically, two identical electric slide rails 2, sliders 3 and connecting columns 4 are provided and are symmetrically distributed about the center line of the base 1. The advantage is that during use, when the movable plate 5 needs to be moved, the electric slide rail 2 is started, the electric slide rail 2 drives the slider 3 to move, the slider 3 drives the connecting column 4 to move, and the connecting column 4 drives the movable plate 5 to move.

[0028] Specifically, the center lines of the drive motor 6, the rotating shaft 7, the turntable 8 and the workbench 9 are located on the same vertical line, and the center lines of the drive motor 2 10, the rotating shaft 2 11 and the electric telescopic rod 12 are located on the same vertical line.

The advantage is that during use, when height adjustment is required, the height is adjusted through the first electric telescopic rod 12 and the second electric telescopic rod 18, so that the first buffer block 15 and the second buffer block 17 fix the workpiece. Since the limit block 19 and the limit groove 21 are adapted to each other, the limit block 19 is aligned with the limit groove 21 and inserted, so that the limit block 19 completely enters the inside of the limit groove 21, and fixation can be completed.

[0033] Specifically, the workbench 9 has a hexagonal structure, and the center lines of the first cylinder 14, the first buffer block 15 and the workbench 9 are located on the same vertical line. The advantage is that during use, since the workbench 9 has a hexagonal structure, workpieces of different specifications can be placed on the workbench 9. Since the center lines of the first cylinder 14, the first buffer block 15 and the workbench 9 are located on the same vertical line, during processing, the workpiece will be processed based on the center line of the workbench 9.

[0034] Working principle: When in use, place the workpiece on the workbench 9, start the second cylinder 16, drive the second buffer block 17 to move downward through the second cylinder 16, so that the second buffer block 17 presses against the workpiece to fix the workpiece. Start the first cylinder 14, drive the first buffer block 15 to move downward through the first cylinder 14, so that the first buffer block 15 fixes the workpiece. When height adjustment is required, the height is adjusted through the first electric telescopic rod 12 and the second electric telescopic rod 18, so that the first buffer block 15 and the second buffer block 17 fix the workpiece. When the workpiece needs to be rotated, start the first driving motor 6, drive the first rotating shaft 7 through the first driving motor 6, drive the turntable 8 to rotate through the first rotating shaft 7, and the turntable 8 drives the workbench 9 to rotate. When the top plate 13 needs to be rotated, start the second driving motor 10, drive the first electric telescopic rod 12 through the second driving motor 10, and the first electric telescopic rod 12 drives the top plate 13 to rotate. When the movable plate 5 needs to be moved, start the electric slide rail 2, the electric slide rail 2 drives the slider 3 to move, drive the connecting column 4 to move through the slider 3, and the connecting column 4 drives the movable plate 5 to move. Since the limit block 19 and the limit groove 21 are adapted to each other, the limit block 19 is aligned with the limit groove 21 and inserted, so that the limit block 19 completely enters the inside of the limit groove 21, and fixation can be completed. Since the workbench 9 has a hexagonal structure, workpieces of different specifications can be placed on the workbench 9. Since the center lines of the first cylinder 14, the first buffer block 15 and the workbench 9 are located on the same vertical line, during processing, the workpiece will be processed based on the center line of the workbench 9.
