Abstract
A power clamp includes a body member (2), an arm member (14) connected to the body member by means of a pivot joint (16) to allow pivoting movement of the arm member between an open position and a closed position, an actuator (10), a first drive mechanism (42) connecting the actuator (10) to the arm member (14) to control movement thereof, and a second drive mechanism (20,28) connecting the actuator (10) to the arm member (14) to apply a clamping force to the arm member when the arm member is in a closed position.
Claims11
A power clamp comprising:
- a body member,
- a rigid clamping arm connected to the body member by means of a pivot joint to allow pivoting movement of the clamping arm between an open position and a closed position, said pivot joint being mounted in a fixed position relative to the body member;
- an actuator mounted in said body member for substantially rectilinear reciprocating movement relative thereto;
- a first drive mechanism connecting the actuator to the clamping arm to control movement thereof, said first drive mechanism being constructed and arranged to convert linear motion of the actuator into rotational movement of the clamping arm about said pivot joint between an open position and a closed position;
- and
- a second drive mechanism comprising a first drive element that is associated with the clamping arm and a second drive element that is associated with the actuator, said second drive mechanism being constructed and arranged such that when said clamping arm is in the closed position, said second drive element engages said first drive element to apply a clamping force to the clamping arm.
