Embodiment Construction
[0033] Figure 1 to Figure 4 , the sectional view of the jointed connection of the threaded sleeve 1 in the hollow profile 3 consists of two halves A and B with respect to the axis of symmetry S (symmetry), which show the method according to the invention in two different process steps Install the threaded sleeve 1 into the hollow profile 3, where half-figure A is the state before the method starts, and half-figure B is the state after the method is implemented.
[0034] also Figure 1 to Figure 4 Elements or components that are the same or have the same function have the same reference numerals.
[0035] figure 1 It is a cross-sectional view of a joint connection showing the two side walls 3c and 3d of the hollow profile 3 with the same diameter of the through-hole 4a of the side wall 3c or the through-hole 4b of the side wall 3d. A radially symmetrical threaded sleeve 1 with an inner hole 1b with a thread 1c is inserted through the through hole 4a into the hollow profile ...

The invention relates to a method for inserting a sleeve (1), preferably a threaded sleeve, into a workpiece (3) by inserting the sleeve (1) into a passage (4a, 4b) that connects two bounding surfaces (3a, 3b) of the workpiece (3), in which a radial circumferential flange (1a) at one end of the sleeve (1) lies against the one bounding surface (3a) and a contact surface (2a) of an engagement element (2) lies against the other bounding surface (3b), wherein the engagement element (2) is joined to the sleeve (1) by a form fit so that the workpiece (3) is clamped between the flange (1a) of the sleeve (1) and the contact surface (2a) of the engagement element (2) via the two bounding surfaces (3a, 3b). According to the invention, the engagement element (2) has a joining section (2b), which partially protrudes into the sleeve (1) and which is sealed to the sleeve (1) by plastic deformation by means of a stamping tool (5) inserted into the sleeve (1). According to an alternative solution, the workpiece (3) is designed as a hollow profiled element, which is bounded in the direction of the passage bore (4a, 4b) by two side walls (3c, 3d) that form the bounding surfaces (3a, 3b), the sleeve (1) has, at an end face, a collar (1e) that encloses the bore (1b) of the sleeve and that protrudes beyond the end face (1f) of the sleeve, the passage bore (4b) of the side wall (3d) of the workpiece (3) lying against the contact surface (2a) of the engagement element (2) substantially corresponds to the outer diameter of the collar (1e), the engagement element (2) is designed as a base plate (2c) that comprises the contact surface (2a) and that has a bore (12) that encloses the collar (1e), and the collar (1e) protruding beyond the base plate (2c) is pressed radially outwardly with the edge of the bore (12) of the base plate (2c) and the edge of the passage (4b) in the side wall (3d).
Description
technical field [0001] The invention relates to a method for inserting a threaded sleeve into a workpiece, and to a joint connection between the threaded sleeve formed according to the method according to the invention and a hollow profile as a workpiece. Background technique [0002] A similar fastening device is described by US2957196A for connecting lightweight panels and structural elements. The weighted panels include a honeycomb structure arranged between two outer panels. The fastening device designed to be installed in the lightweight panel consists of two sleeve-shaped parts, each with an end-side flange, which are inserted into the opposite sides of the outer panel. It is placed in the opening and rests on the outer plate with the flange on the end side. The two parts are telescopically inserted into one another with their end sides opposite the flange, so that the round, threaded end sides of the inserted part are pressed against the received part by means of a ...
