Example of Use
Equipment name: Embedded fixture
Function description:
It is an embedded assembly fixture that can be embedded into rubber workpiece and aluminum workpiece, embedding the rubber convex part into the concave part of another workpiece. Load can be adjusted with bolt and compressed by roller.
Functions of rotary shafts in the mechanism
①The rotary shaft is used as a tightening connector in the mechanism, bearing the pressure applied by the spring, and connected to roller for compressing the workpiece.
②Excellent roundness and linearity, allowing the assembly fixture to apply force evenly, thereby improving overall stability of the tooling.
