Clamped end manipulators are widely used in robots, automated production lines and other fields, and their clamping methods mainly include two-claw clamping, three-claw clamping, four-claw clamping, pneumatic clamping and vacuum chuck clamping:

1. Two-claw clamping: This method is the most common clamping method, which uses two symmetrical mechanical arms to clamp, and is suitable for clamping objects with various shapes such as circle, square and hexagon.

2. Three-jaw clamping: This method uses three mechanical arms to clamp, which is suitable for clamping irregular objects, such as spheres and ellipses.

3. Four-claw clamping: This method uses four mechanical arms to clamp, and the clamping force is more uniform, which is suitable for clamping larger objects.

4. Pneumatic clamping: This method uses pneumatic components for clamping, which has the advantages of fast clamping speed and large clamping force, and is suitable for high-speed automatic production lines.

5. Vacuum chuck clamping: This method uses vacuum chuck to clamp, which is suitable for clamping flat objects, such as glass plates and metal plates.
