When the two hinge points of the connecting rod and the connecting rod and the hinge point of one of the connecting rods and the frame, the three points are in a straight line, the mechanism is at the dead point position. At this time, the pressed workpiece, no matter how much reaction force (except the destructive reaction force), can not loosen the indenter, which is the dead center clamping principle in mechanical mechanics.
In order to avoid the influence of external force load and mechanical vibration during use, the intermediate hinge point is designed to be slightly offset from the inner side of the other two hinge points to ensure that the clamp is always maintained at the maximum central tension. The mechanism is locked in a steady state and not loose.
Central tightening force of the tightening force is central <br> <br> clamp means in the case of the locked position, no mechanical deformation, the maximum indenter pressing force to the workpiece, and this pressing force is generated to force the ram arm is adjusted The closest location to the mount.
The pressure of the indenter on the workpiece is not constant, it varies with the position of the indenter on the arm, and the clamping force is reduced when it is away from the mount.
Characteristics
The structure is simple and easy to install.
The clamped workpiece is quick to load and unload, and the operation is convenient.
All parts are treated with anti-rust treatment and the surface is smooth and beautiful.
For heavy-duty fixtures, the key parts are heat-treated to provide high strength and wear resistance.

Briefly describe the clamping principle of fast fixtures
Quick clamping fixture jig such <br> <br> principle is based on mechanical principle planar four bar linkage mechanism to double rocker design, the basic structure is composed of four rod member, and two rack rods and other components joined to the frame .
