Q:What functions should be achieved in mechanical structure design?

The function of the mechanical structure is mainly realized by the geometry of the machine parts and the relative position between the parts. The geometry of a part is made up of its surface, and a part usually has a number of surfaces, some of which are in direct contact with the surface of other parts, and this part of the surface is referred to as the functional surface. The connecting part between the functional surfaces is called the join surface
