Make Shortcut to Home Screen? Toggle Joint A toggle joint mechanism can be used to multiply force. Sponsored Links. The horizontal force acting in point 3 can be calculated for arms with equal or unequal lengths.

Modify access date. Once in the over-center position, the clamp cannot move or unlock unless the linkage is moved.

All types of toggle clamps have the same action, just oriented differently. To multiply a hand force at the handle into a high clamping force to hold work. To create an over-center lock to prevent the clamp from opening and releasing the work until opened by the operator. To rapidly open and close the clamp giving a wide clearance in which to load and unload the workpiece. The toggle clamping mechanism is widely used in the manufacturing industry in areas like bending, grinding, welding, fitting, etc.

Toggle mechanisms are commonly used within linkages in order to lock their position. A generic toggle mechanism can be considered as a good mix of a couple of traditional linkages, a four-bar linkage, and a slider-crank mechanism. Ground link is represented by link C and other details are;. Element Details;. Clamping member, A is an output link which holds the clamping jaw. Output link velocity and the force available at the output link which holds or clamp the workpiece is a function of the mechanism configuration, link position, link lengths, joint friction, and actuator parameters.

Force amplification ratio is the key design parameter toggle clamping mechanism. Performance of the toggle clamp mechanism is based upon the force available at the clamping location which is output link.

The clamping force available at the output link is the function of the input cylinder force, the geometric position of all the links, the coefficient of friction between moving and turning parts.
