Abstract
A gripper mechanism configured to clamp an object includes at least one pair of clamping arms, a connecting element hinging at least one pair of clamping arms, a power cylinder driving the connecting element to move, and a limiting element with a through slot. The clamping arms pass through the through slot and connect to the limiting element. The power cylinder can drive the connecting element to move opposite or to move closer, thus (respectively) closing the clamping arms together or causing them to open.
Claims7
A gripper mechanism for clamping an object, the gripper mechanism comprising:
- at least one pair of clamping arms;
- a connecting element configured to hinge to the at least one pair of clamping arms;
- a power cylinder configured to connect to the connecting element and drive the connecting element to move;
- and
- a limiting element comprising through slots, the at least one pair of clamping arms passing through the through slots and rotatably connecting to the limiting element, wherein when the power cylinder drives the connecting element to move opposite from the power cylinder, the connecting element drives an end of each clamping arm opposite from each other, which makes the other end of each clamping arm close inwardly to grab the object, and when the power cylinder drives the connecting element to move toward to the power cylinder, the connecting element drives an end of each clamping arm closer to each other, which makes the other end of each of the clamping arms open outward to release the object, wherein the power cylinder comprises a main body and one movable rod at one end of the main body, the movable rod connects to the connecting element and is driven to move into or out of the main body, the connecting element comprises a first cylindrical block and a second cylindrical block coaxial with the first cylindrical block, the first cylindrical block connects to the movable rod of the power cylinder, the second cylindrical block comprises a first slot and a second slot, the first slot is defined by two first slot walls, the second slot is defined by two second slot walls.
