Example of Use
Equipment Name: Embedded Fixture
Function Description:
An insert assembly jig for embedding into rubber and aluminum workpieces, allowing the protruding part of the rubber to be inserted into the recessed part of another workpiece. The load can be adjusted using bolts and tightened with the roller.
The Role of the Shaft in Mechanisms
(1) The shaft is used as a fastening connector in mechanisms, bearing the pressure applied by the spring and connecting the roller to press the workpiece.
(2) Excellent roundness and straightness ensure even force distribution during use of assembly jigs, enhancing the overall stability of the fixture.
