Abstract:
Process for automatically screw-connecting first and second components by a torque-controlled tightening method with an automatic fitting machine and at least one connecting element which screw-connects the components,wherein each of said at least one connecting element has two same-direction threaded sections of different pitches and each threaded section is screw-connected to one component in each case, with the following process steps for completing the fitting operation:rotary-angle-controlled preliminary tightening of each of said at least one connecting element,termination of the rotary-angle-controlled preliminary tightening at the end of a predetermined rotational angle which substantially corresponds to contact between mutually facing surfaces of the components which are to be connected, andtorque-controlled definitive tightening until a predetermined final torque value has been reached.
