Introduction to the relevant principles of Pneumatic Toggle Clamps

A Pneumatic Toggle Clamp can adjust the distance. Pneumatic Toggle Clamps are suitable for various clamping applications. These self-locking Pneumatic Toggle Clamps can provide excellent clamping force and clamping function. When processing a workpiece on a machine tool, to make the surface of the workpiece meet the technical requirements such as the size and geometric shape specified in the drawing, the workpiece must be positioned and clamped before processing.  Next, let us understand the relevant principles of Pneumatic Toggle Clamps. Here are some answers.

The clamping principle of the Pneumatic Toggle Clamp.

When the connecting rod, the connecting frame rod, and the three hinge points of the frame are in the same straight line, the mechanism is at the dead center position. At this time, the compressed workpiece will not change at will. The pressure head will not loosen. This is the dead-point clamping principle. The positioning of the workpiece is to place the workpiece on the workbench of the machine tool or in the Pneumatic Toggle Clamp so that there is a relatively correct position between it and the tool. And clamping is to fix the workpiece after the workpiece is positioned so that it keeps the unit position unchanged during the processing.

The design principle of Pneumatic Toggle Clamp.

To avoid the influence of external force load changes and mechanical vibration in the use of Pneumatic Toggle Clamps. When designing a Pneumatic Toggle Clamp, place the middle hinge point slightly inside the connection of the other two hinge points. To ensure that under the maximum clamping force, the Pneumatic Toggle Clamp always keeps the clamp mechanism locked in a stable state without loosening. Without mechanical deformation of the clamp in the locked position, the maximum pressing force of the indenter on the workpiece is the clamping force. This pressing force is produced when the indenter is adjusted to the position closest to the mounting seat on the lever arm. The pressure of the indenter on the workpiece is not constant. It varies with the different positions of the indenter on the arm. When it is far away from the mounting seat, the clamping force decreases.
