The box centering clamping device according to claim 5, wherein reinforcing rib plates (2.9) are further fixed at two included angle side surfaces of the L-shaped clamping plate (2.8), strip-shaped sliding grooves are formed in the reinforcing rib plates (2.9), a top block fixing plate (2.11) is movably arranged between the two strip-shaped sliding grooves and is fixed through bolts, one end of each top block (2.12) is fixed to the middle of the corresponding top block fixing plate (2.11), and the other end of each top block (2.12) is abutted to the corresponding V-shaped stop block (3.5).
7. The box centering and clamping device according to claim 1, wherein a pair of limiting grooves are relatively arranged in parallel in the second substrate (1.2), box cushion blocks (2.5) are arranged in the limiting grooves in a rolling mode, and a plurality of rollers (2.16) are rotatably arranged at the bottoms of the box cushion blocks (2.5).
8. A clamping method using the box centering clamping device according to any one of claims 1 to 7, characterized by comprising the steps of:
1) Placing the box body on a box body cushion block (2.5), driving a first gear (1.9) to rotate by an operator through rotating a rocking disc (1.4), then driving a hinge point of connecting rods (1.3) on two sides of the first gear (1.9) to do circular motion around the center point of the first gear (1.9), and simultaneously enabling a pushing gear (1.7) at the end part of the connecting rod (1.3) to roll on a second rack (1.6);
2) The second rack (1.6) rolls and simultaneously the first rack (1.5) above the second rack (1.6) and the pushing gear (1.7) move relatively, and finally the pushing gear (1.7) drives the clamping plate module (2) to move by a distance equal to twice the horizontal movement distance of the single connecting rod (1.3), the second rack (1.6) rotates, and the two connecting rods realize bidirectional driving so as to enable the two clamping plate modules (2) to move in opposite directions by four times of travel;
3) When clamping plate modules (2) on two sides are abutted against two sides of a box body, a cylinder (3.2) is started to shrink a piston rod, when a long connecting rod (3.3) and a short connecting rod (3.4) are collinear, self-locking can be achieved, the short side of a V-shaped stop block (3.5) is perpendicular to the short connecting rod (3.4), meanwhile, the long side of the V-shaped stop block (3.5) is abutted against a corresponding top block (2.12), and the maximum torque is provided to offset torque generated by pushing the top block (2.12) in the horizontal direction.
