Abstract
The present invention provides a low-cost electric clamping device in which a toggle linkage can be actuated by a small low-torque electric motor. The device includes a gear speed reducing mechanism connected to the electric motor, a linkage connected to the speed reducing mechanism, a clamp arm shaft connected to the linkage, and a body 2 for housing them. The linkage includes a crank link connected to a last-stage spur gear of the speed reducing mechanism, a cam follower link which is connected at one end thereof to the crank link and to which a cam follower moving on cam rail faces is rotatably mounted, and a driving lever to which the other end of the cam follower link is connected and which projects from the clamp arm shaft.
