The sliding block 5 is connected with the V-shaped block 8 through a taper pin positioning 6 and a slotted screw 7, so that the two blocks are relatively fixed;
the feeding servo system comprises a servo motor 1, the servo motor 1 is fixed on a base 16 and is connected with a first screw rod 13 through a coupler 2, the first screw rod 13 is connected with a sliding block 5 through a nut 12, the sliding block 5 is connected with a guide rail 10, when the servo motor 1 starts to work, the servo motor 1 drives the first screw rod 13 to rotate through the coupler 2, the first screw rod 13 is fixed by a deep groove ball bearing 4 and rotates relative to the nut 12, the nut 12 is fixed on the sliding block 5, and therefore when the sliding block 5 is driven to move, a clamping seat of a V-shaped block 8 generates feeding displacement, and a workpiece is clamped;
the base 16 is mainly used for fixing the servo motor 1 and the guide rail 10 and limiting the axial movement of the first screw 13;
the guide rail 10 is fixed on the base 16, and the sliding block 5 slides on the guide rail 10 to generate relative motion;
the type selection of the servo motor is as follows: 40st-m 00330; selecting the coupler type: a high-precision plum coupling LM-14;
the flange special automatic clamp is designed on the basis of the theory such as material mechanics, modern structure tests and optimization design from the aspects of the structure of the flange special automatic clamp, and the technology such as two-dimensional and three-dimensional modeling software and mechanical optimization design is utilized.
