This kind of quick clamp is designed according to the mechanical principle of the double rocker mechanism in the Four-bar linkage.
When the two articulation points of the connecting rod and the connecting rod and the articulation point of one connecting rod and the frame are in a straight line, the mechanism is in the dead point position. At this point, the compressed workpiece, no matter how much reaction (except destructive reaction) , can not make the pressure head loose, this is the dead-point clamping principle in mechanical mechanics.
In order to avoid the influence of external load change and mechanical vibration in use, the middle hinge point is slightly deviated from the inner side of the line of the other two hinge points in design to ensure that in the case of central tight force, always keep the fixture mechanism locked in a stable state without loosening.
The central tightening force is the pressure of the pressure head on the workpiece when the fixture is in the locked position without mechanical deformation.
The pressure of the pressure head on the workpiece is not constant, it varies with the pressure head in different positions on the arm, when away from the mounting seat, the clamping force decreases.
Features:
Simple structure and easy installation.
The workpiece is clamped for quick loading and unloading, and the operation is convenient and fast.
All parts by plating rust-proof treatment, the surface is smooth and beautiful.
For heavy duty fixture, its key parts have been heat-treated to make it have higher strength and wear resistance.
