The linkage positions shown below with an angle α = 0 o and 180 o has a near infinite mechanical advantage. These positions are referred to as toggle positions. These positions allow the 4 bar linkage to be used a clamping tools.
Toggle joint definition is - a device consisting of two bars jointed together end to end but not in line so that when a force is applied to the knee tending to straighten the arrangement the parts abutting or jointed to the ends of the bars will experience an endwise pressure which increases indefinitely as the bars approach a straight-line ...

May 24, 2017· toggle joint (plural toggle joints) A mechanical linkage of the type of an elbow or knee joint, consisting of two bars so connected that they may be brought quite or nearly into a straight line, and made to produce great endwise pressure when brought into this position.
Chapter. 4 Mechanism Design and Analysis 9All mechanical devices containing moving parts are composed of some type of mechanism. 9A mechanism is a group of links interacting with each other through joints to complete required motion or force transmission. 9There are 5 fundamental questions to be considered when designing a mechanism: 1.

Clamping Force Calculator Clamping force refers to the force applied to a mold by the clamping unit of an injection molding machine. In order to keep the mold closed, this force must oppose the separating force, caused by the injection of molten plastic into the mold.
25 Knuckle-joint and toggle presses 25.1 Single-point knuckle-joint presses Knuckle-joint presses (Figure 25.1) are a special kind of crank press where the crank force is produced via a (knuckle joint) joint system. In principle, the rules which govern a crank press apply here, both as concerns the construction design and the way it works.
Nov 06, 2013· I've searched everywhere trying to work out how to calculate the spreading force of a simple toggle mechanism. I have a two equal length arms that are hinged together. One end is fixed on a pivot pin and the other can slide along a flat plane but is resisted by a fixed stop.
Arrange the apparatus in given position. Then load the effort weight hanger and note the corresponding force on the spring balance. Then perform calculation according to pattern given in table.
The forward link of the joint is attached by a similar pin to the rear of the breech block. Throwing the lever down (forward), which is attached to the middle of the toggle by a pin, collapses the toggle and slides the breech block out of battery to extract the fired case.

A mechanical linkage is an assembly of bodies connected to manage forces and movement. The movement of a body, or link, is studied using geometry so the link is considered to be rigid. The connections between links are modeled as providing ideal movement, pure rotation or sliding for example, and are called joints.
