[0014] A method for using a vehicle plate cutting device comprises the following steps: S1. Pretreatment of vehicle plates: First, the plate surface must be inspected and the thickness measured, then the vehicle plates are cleaned using external cleaning equipment, and the deformed metal plates are corrected using external correction equipment; S2, clamping and fixing of vehicle plates; S2.1. Adjust the pneumatic clamping position according to the bending degree of the vehicle plate: First, adjust the suction cup according to the bending degree of the vehicle plate, loosen the first adjustment plates by twisting the adjustment nut, and adjust according to the bending degree of the plate, and then twist the adjustment nut to fix the first adjustment plates, so that the pneumatic clamp can adapt to various shapes of vehicle plates such as curved plates and flat plates; S2.2. Adjust the position of the suction cup according to the size of the vehicle plate: After adjusting the pneumatic clamp, the position of the movable frame can be adjusted according to the size of the vehicle plate. When the size of the vehicle plate is small, the second cylinder can be operated through the external circuit mechanism, and the second cylinder drives the movable frame to move on the top of the support frame. In this process, the second cylinder is driven to rotate through the fixed frame, so that the movable frame reciprocates through the second cylinder, and every two movable frames move toward the fixed frame, so that the fixed frame and the movable frame are gathered together, and the first air pump is operated to extract the gas between the suction cup and the vehicle plate, so that the vehicle plate is fixed.

[0015] Compared with the prior art, the present invention has the following beneficial effects: 1. The present invention can adjust the height of the suction cup by setting a pneumatic clamping mechanism to achieve two different clamping methods for curved plates and flat plates. When clamping curved plates, a semi-wrapped pneumatic clamping effect is achieved to avoid displacement of vehicle plates during processing. By adopting a pneumatic clamp, it can avoid contact between metal plates and metal parts, which causes surface wear. At the same time, by setting an adjustment component, the three-axial movement of the cutting head can be achieved. Moreover, through the parallel mechanism, the cutting head can be rotated and its angle can be adjusted, which is beneficial to improving the reliability of the device.

[0016] 2. The present invention sets a transmission ring so that the suction cup can tilt according to the curve of the plate surface, thereby increasing the contact area between the suction cup and the curved plate. At the same time, a conical spring applies a force to the limit cylinder so that the suction cup is always in contact with the surface of the curved plate, which is beneficial to improving the sealing between the suction cup and the plate.

[0017] 3. The present invention loosens two adjacent first adjustment plates by twisting the adjustment nut, and adjusts the position of the first adjustment plates according to the bending degree of the curved plate. At the same time, the second cylinder drives the movable frame to move on the top of the support frame, so that the suction cup can adapt to the clamping and fixing function of vehicle plates of different sizes, and by gathering the folding plate to the middle, a plurality of suction cups can be adjusted to achieve a semi-wrapped clamping and fixing effect of the vehicle plate, which is conducive to improving the adaptability and extensiveness of the device.

[0018] 4. The present invention provides a first telescopic rod, and cross axes are respectively provided at both ends of the first telescopic rod, so that the first telescopic rod can be tilted, and a force is applied to the first telescopic rod by a third cylinder to cause the first telescopic rod to tilt, thereby realizing three-axial movement of the cutting head.
