Toggle clamps are widely used in packaging machinery for mounting machine components. Usually they are used for parts that require frequent removal for cleaning or changeover.
They come in a variety of formats and sizes. Frequently they are manually toggled but pneumatically and hydraulically actuated clamps are available as well. Some configurations are double acting, toggling in either the extended or retracted position.
Generally, the toggle clamp should never be the primary means of holding a part in position. Use some locating pins with corresponding mating pins. The part mates with the pins that prevent it from moving side to side. The toggle clamp provides a vertical force to prevent the part from lifting off the pins.
