After fixing, the machine door 26 is pulled by the handle 27 to close the door 28, so as to prevent debris from splashing out of the machining center body 1 when processing the sharp-surface workpiece.

[0040] When used specifically, the present invention is used as a horizontal machining center. First, the operator pulls the handle 27 to make the machine door 26 open the door 28. Then the operator can put the sharp-surfaced workpiece on the rotating disk 19 for fixed processing. The dual-axis motor 13 drives the threaded rod 14 to rotate, so that the threaded rod 14 drives the two moving blocks 15 to move toward each other, and then the moving blocks 15 drive the two lifting boxes 7 to move toward each other through the electric telescopic rod 16, and the lifting boxes 7 drive the moving frames 6 at both ends to move toward each other along the inner wall of the fixed frame 20, so that the lifting boxes 7 drive the elastic cloth bag 9 to squeeze and fix the lower end of the sharp-surfaced workpiece through the driven wheel 21 and the rotating block 8. After fixation, the machine door 26 is pulled by the handle 27 to close the door 28.

[0041] When the side of the sharp-surfaced workpiece needs to be processed, the threaded rod 14 is driven to rotate by the dual-axis motor 13, so that the threaded rod 14 drives the two moving blocks 15 to move oppositely, and then the moving blocks 15 drive the two lifting boxes 7 to move oppositely through the electric telescopic rod 16, and the lifting boxes 7 drive the moving frames 6 at both ends to move oppositely along the inner wall of the fixed frame 20, so that the lifting boxes 7 drive the elastic cloth bag 9 to move through the driven wheel 21 and the rotating block 8, thereby releasing the fixing effect on the sharp-surfaced workpiece, and then the operator starts the brake motor 17, so that the rotating rod 18 drives the sharp-surfaced workpiece to rotate through the rotating disk 19, until When the sharp-surfaced workpiece rotates to a suitable position, it stops. Then the operator drives the threaded rod 14 to rotate through the dual-axis motor 13, so that the threaded rod 14 drives the two moving blocks 15 to move toward each other, and then the moving blocks 15 drive the two lifting boxes 7 to move toward each other through the electric telescopic rod 16, and the lifting boxes 7 drive the moving frames 6 at both ends to move toward each other along the inner wall of the fixed frame 20, so that the lifting boxes 7 drive the elastic cloth bag 9 to squeeze and fix the side of the sharp-surfaced workpiece through the driven wheel 21 and the rotating block 8, and then the operator can drive the spindle box 3 to move up and down through the driving mechanism 2, so that the rotating tool 4 can process the side of the sharp-surfaced workpiece.

[0042] When the bottom surface of the sharp-faced workpiece needs to be processed, the operator starts the dual-axis motor 13, thereby driving the threaded rod 14 to rotate through the dual-axis motor 13, so that the threaded rod 14 drives the two moving blocks 15 to move in opposite directions, and then the moving blocks 15 drive the two lifting boxes 7 to move in opposite directions through the electric telescopic rod 16, and the lifting boxes 7 drive the moving frames 6 at both ends to move in opposite directions along the inner wall of the fixed frame 20, so that the lifting boxes 7 drive the elastic cloth bag 9 to move through the driven wheel 21 and the rotating block 8, thereby releasing the sharp-faced workpiece. The sharp-surface workpiece is fixed, and then the operator starts the electric telescopic rod 16, so that the electric telescopic rod 16 drives the lifting box 7 to move upward along the inner wall of the moving frame 6, and then the lifting box 7 drives the gear block 24 to move through the driving wheel 23. At this time, since the gear block 24 is meshed with the toothed block 25, the gear block 24 drives the driving wheel 23 to rotate through the fixed toothed block 25, so that the driving wheel 23 drives the driven wheel 21 to rotate through the transmission belt 22, and the elastic cloth bag 9 stops when it moves to the upper end of the sharp-surface workpiece. At this time, by starting the double-axis motor 13, the double-axis motor 13 drives the threaded rod 14 to rotate, so that the threaded rod 14 drives the two moving blocks 15 to move toward each other, and then the moving blocks 15 drive the two lifting boxes 7 to move toward each other through the electric telescopic rod 16, and the lifting boxes 7 drive the moving frames 6 at both ends to move toward each other along the inner wall of the fixed frame 20, so that the lifting boxes 7 drive the elastic bag 9 to squeeze and fix the upper end of the sharp surface workpiece through the driven wheel 21 and the rotating block 8, and then continue to start the electric telescopic rod 16, so that the electric telescopic The rod 16 drives the lifting box 7 to move upward as a whole, so that the gear block 24 continues to drive the driven wheel 21 to rotate through the tooth groove block 25, so that the driven wheel 21 can drive the squeezed and fixed sharp-surface workpiece to flip through the rotating block 8 and the elastic cloth bag 9 and the rubber hollow ball 10, and then drive the spindle box 3 to move up and down through the driving mechanism 2, so that the rotating tool 4 can process the bottom surface of the sharp-surface workpiece, so that the rotating tool 4 can process the bottom surface of the sharp-surface workpiece, thereby making the device more comprehensive when processing the sharp-surface workpiece.
