The clamping plate 4 can clamp a certain number of rectangular or box-like workpieces stored at the same time.

[0026] A bolt hole 402 is provided inside the clamping plate 4, a positioning bolt 301 is movably installed between the movable plate 3 and the clamping plate 4, and the positioning bolt 301 is threadedly connected to the bolt hole 402, the top of the support frame 5 is fixedly connected to the fixing frame 2, the top of the fixing frame 2 is fixedly connected to the hydraulic rod 11, the bottom of the hydraulic rod 11 is fixedly connected to the fixing plate 12, the bottom of the fixing plate 12 is fixedly connected to the suction cup 13, and the suction cup 13 is provided with three groups, the clamping plate 4 and the movable plate 3 are movably connected through a hinge, when it is necessary to grab the workpiece of opposite sex, first unscrew the positioning bolt 301, pull to both sides to lift the clamping plate 4, the clamping plate 4 is rotated and lifted by the hinge shaft to form a 90° angle with the movable plate 3, and then the positioning bolt 301 is screwed back between the movable plate 3 and the clamping plate 4 to the inside of the bolt hole 402, so that the positioning bolt 301 contacts with the clamping plate 4, increasing the friction between the movable plate 3 and the clamping plate 4, so that the clamping plate 4 can be fixed, and the hydraulic rod 11 is controlled to push the fixed plate 12 down, and the fixed plate 12 drives the suction cup 13 to go down, so that the suction cup 13 contacts with the workpiece, and then the external vacuum equipment is used to vacuum the suction cup 13, so that the suction cup 13 adsorbs the special-shaped workpiece, and then the external driving and adjusting equipment is controlled to move the workpiece, so as to realize the clamping and movement of the special-shaped workpiece. When it is necessary to grasp a heavier workpiece, the clamping plate 4 can be ignored. First, the motor 6 is controlled to drive the threaded rod 7, so that the clamping plate 4 clamps the workpiece, and then the hydraulic rod 11 is controlled to push the suction cup 13 to contact with the top of the workpiece, and the suction cup 13 is vacuumed, so that the suction cup 13 adsorbs the workpiece, so as to realize the simultaneous adsorption, lifting and clamping of heavier workpieces.

[0027] Reference Figure 4, a positioning rod 9 is fixedly connected inside the support frame 5 at one end of the threaded rod 7, and the positioning rod 9 passes through the movable plate 3. A jack adapted to the size of the positioning rod 9 is provided inside the movable plate 3. The positioning rod 9 can guide and limit the moving direction of the movable plate 3, improving the stability effect of the movement of the movable plate 3.

The support frame 8 connects and fixes the mounting plate 10 to the support frame 5. A plurality of fixing holes are provided inside the mounting plate 10, and the staff can use external bolts to fix an external driving device to the mounting plate 10.

[0029] The implementation principle of the grasping gripper structure of a case-packing machine in an embodiment of this application is as follows: When the staff is clamping rectangular or box-shaped workpieces, they control the motor 6 to drive the threaded rod 7 to rotate, so that the movable plate 3 drives the clamping plate 4 to approach another clamping plate 4 through the threaded rod 7, enabling the clamping plate 4 to clamp the workpiece. Cooperating with an external driving and adjusting device to move the workpiece, the clamping and moving of rectangular and box-shaped workpieces are realized. When it is necessary to grasp irregular workpieces, first unscrew the positioning bolt 301, pull and lift the clamping plate 4 to both sides, and then use the positioning bolt 301 to fix the clamping plate 4, so that the clamping plate 4 does not affect the clamping operation of the suction cup 13. Control the hydraulic rod 11 to push the fixing plate 12 downward, and the fixing plate 12 drives the suction cup 13 to descend until it contacts the workpiece. Then use an external vacuum pumping device to pump the suction cup 13 to vacuum, so that the suction cup 13 adsorbs the irregular workpiece. Then control the external driving and adjusting device to move the workpiece, realizing the clamping and moving of the irregular workpiece. The staff can, when it is necessary to grasp heavier workpieces, first control the motor 6 to drive the threaded rod 7, so that the clamping plate 4 clamps the workpiece, and then control the hydraulic rod 11 to push the suction cup 13 to contact the top of the workpiece, pump the suction cup 13 to vacuum, so that the suction cup 13 holds the workpiece, realizing the simultaneous adsorption and clamping of heavier workpieces.
