Abstract
The invention relates to a device (10, 30) which is used to produce a screw connection between a first component (14, 60) and at least one additional component (15, 70), by means of a fixing screw (12) or a fixing groove (50, 55) and a corresponding fixing element (16, 73). Said device (10, 30) comprises a rotationally mounted tool (11, 31), wherein the fixing screw (12) and/or the fixing groove (50, 55) is maintained in a manner that prevents it from rotating and in an axially fixed manner and wherein the head (20) of the fixing screw (12) and/or the fixing groove (50, 55) is maintained at a distance (S) in relation to the first component (14, 60) as long as both components (14, 60; 15, 70) are joined together. According to the invention, at least one energy accumulator (18, 48) is provided between the tool (11, 31) and the first component (14, 60). At least the joining force and the maximum and the total desired clamping force of the prepared screw connection can be predetermined by means of the at least one energy accumulator (18, 48). The invention also relates to a fixing groove (50, 55) for the inventive device and/or the inventive method.
