The invention relates to a device (1) for connecting components (2, 3) by clamping and by means of a spacer (7) which is arranged in the gap and a clamping component (15) which clamps the two components (2, 3) against each other, said components being situated at a distance from one another. The fixing movement of the clamping component (15) results in a displacement of the spacer (7) from a distanced position into a position of rest on the second component (3) and then results in the device being fixed to the first component (2) by means of clamping elements (13) that are brought to rest on the wall of an insertion cavity (6) pertaining to the first component (2). According to the invention, the spreading means (13) are allocated to the spacer (7).
A device (1) for connecting components (2, 3) which lie at a spacing from one another by clamping by means of a spacer (7), which is disposed in the spacing region, and a clamping piece (15) which clamps the two components (2, 3) with respect to one another, the securing actuation of the clamping piece (15) initially displacing the spacer (7) from a spaced position to a bearing position with respect to the second component (3) and then fixing the device to the first component (2) by means of clamping elements (13) which move into engagement against the wall of an insertion cavity (6) of the first component (2), characterized in that the spreading elements (13) are associated with the spacer (7).
Device according to one or more of the preceding claims or in particular according thereto, characterized by a spreading body (14) which can be displaced toward the second component (3) during the securing actuation and which drags with it the spacer (7), which forms a sleeve, from the spaced position into the bearing position.
Device according to one or more of the preceding claims or in particular according thereto, characterized in that the sleeve (7) is provided with slots (12) which extend in the axial direction, the slot interspaces forming the spreading elements (13).
Device according to one or more of the preceding claims or in particular according thereto, characterized in that the clamping piece (15) is a bolt or a rivet.
Device according to one or more of the preceding claims or in particular according thereto, characterized in that the spacer (7) fits in the insertion cavity (6) in such a manner that it is rotationally fixed but slidably displaceable in the axial direction 6.
Device according to one or more of the preceding claims or in particular according thereto, characterized in that the spacer (7) is a spreading sleeve.
Device according to one or more of the preceding claims or in particular according thereto, characterized in that the insertion cavity (6) is formed by a piece of tube (4) which is fixedly connected to the first component.
Device according to one or more of the preceding claims or in particular according thereto, characterized in that the piece of tube (4) is formed by a drawn-in section.
Device according to one or more of the preceding claims or in particular according thereto, characterized in that the piece of tube (4) is formed by an insertion part (17) which can be spread open.
Device according to one or more of the preceding claims or in particular according thereto, characterized by protuberances (30) which project radially from the insertion part (17), for holding the insertion part (17) in a rotationally and axially fixed manner in a drilled hole.
Device according to one or more of the preceding claims or in particular according thereto, characterized in that the rotational securing is formed by a lug (5) which projects from the insertion cavity and engages in a groove (9) in the sleeve (7).
Device according to one or more of the preceding claims or in particular according thereto, characterized in that the spreading body (14), on account of a pin (23) which engages in a groove (25) in the sleeve (7), is seated in a rotationally fixed manner in the sleeve (7).
Device according to one or more of the preceding claims or in particular according thereto, characterized in that the spreading body (14) forms a conical lateral surface (19) which comes to bear against a conical mating surface (18) of the sleeve (7).
Device according to one or more of the preceding claims or in particular according thereto, characterized in that the pin (23) holds the spreading body (14) on the sleeve (7).
Device according to one or more of the preceding claims or in particular according thereto, characterized in that the mating thread (21, 32) of the clamping bolt is associated either with the second component (3) or with the spreading body (14).
Device according to one or more of the preceding claims or in particular according thereto, characterized in that the spacer (7) has a second spreading body (32), which is arranged opposite the first spreading body (14) and by means of which it comes to bear against the second component (3).
Device according to one or more of the preceding claims or in particular according thereto, characterized in that the spreading sleeve (7), after coming into contact with the second component (3), is deformed, in such a manner as to reduce the spacing, by increasing the clamping force.
Device according to one or more of the preceding claims or in particular according thereto, characterized in that the substantially cylindrical sleeve wall (8) (sic) is circumferentially fluted (16).
Device according to one or more of the preceding claims or in particular according thereto, characterized by slots (12, 25) which start from both end sides of the sleeve, alternate with one another and overlap one another in terms of length in the axial direction.
