Rapid fixture manufacturing improves work efficiency.

As we all know, rapid fixture plays an important role in industrial production. For example, in the mold manufacturing and the workshop operation of heavy industry development, the rapid fixture is needed. The application of quick fixture should start with its material, basic properties, working principle, matters needing attention and other related aspects. Do the tools in hand, and be familiar with them easily, which not only ensures the practicability of the tools, but also improves the work efficiency. Why not?

The quick fixture is designed according to the mechanical principle of double rocker mechanism in planar four-bar mechanism, and its basic structure is composed of four components, including connecting rod, frame and two connecting rods.

When the two hinge points between the connecting rod and the connecting rod and the hinge point between the connecting rod and the frame are in the same line, the mechanism is in the dead center position. At this time, the pressed workpiece, no matter how much counterforce (except destructive counterforce), can't loosen the indenter, which is the principle of dead point clamping in mechanical mechanics.

In order to avoid the influence of external load change and mechanical vibration in use, when designing, the middle hinge point is slightly offset to the inner side of the line connecting the other two hinge points, so as to ensure that the fixture mechanism is always locked in a stable state without loosening under the condition of maximum central tightening force.
