Description
Die Erfindung betrifft eine Montageeinheit mit einem an einer Grundkonstruktion zu fixierenden Montageteil mit einer oder mehreren Durchgangsöffnungen und einem oder mehreren, einen Schaft, einen Kopf und einen Fixierabschnitt aufweisenden Befestigern, welche jeweils mit ihrem Schaft eine Durchgangsöffnung durchgreifen und darin verliersicher gehalten werden.The The invention relates to a mounting unit with a on a basic construction to be fixed mounting part with one or more through holes and one or more, a shaft, a head and a fixing portion having fasteners, which each pass through a through opening with its shaft and held captive in it.
Derartige
Montageeinheiten sind aus
Die Erfindung betrifft weiterhin eine einen Befestiger und eine Hülse umfassende Befestigereinheit. Als Montageteile kommen beispielsweise Zylinderkopfhauben oder Ansaugkrümmer in Betracht, welche an einem Zylinderkopf angeschraubt werden sollen. Um die Kosten seitens der Logistik und der Montage zu reduzieren, sind die Montageteile bereits im Anlieferzustand mit Befestigern bestückt. Damit während des Transports die Befestiger, z. B. Schrauben, nicht vom Montageteil abfallen und verloren gehen, sind Befestiger und Montageteil verliersicher miteinander verbunden. Der Befestiger ist dabei in der Durchgangsöffnung des Montageteils axial beweglich so gehalten, dass er beispielsweise Schwerkraft bedingt in eine Axialposition bewegbar ist, in der sein Fixierabschnitt aus der dem Kopf abgewandten Seite des Montageteils, der Montageseite, vollständig oder zumindest so weit herausragt, dass die gewünschte Einschraubtiefe gewährleistet ist. Beim Aufsetzen des Montageteils mit seiner Montageseite auf eine Grundkonstruktion, was in aller Regel mit Hilfe eines Roboters erfolgt, werden die Fixierabschnitte möglichst vollständig in die Durchgangsöffnungen zurückgeschoben. Eine Beschädigung der mit der Montageseite zusammenwirkenden Montagefläche der Grundkon struktion oder der Fixierabschnitte ist dadurch vermieden. Die aus der Montageseite vorstehenden Fixierabschnitte können aber während der Annäherung des Montageteils an die Gegenfläche stören, beispielsweise an Kanten der Grundkonstruktion oder an Erhebungen der Gegenfläche hängen bleiben.The The invention further relates to a fastener and a sleeve comprising Befestigereinheit. As mounting parts, for example, cylinder head covers or intake manifold into consideration, which are to be screwed to a cylinder head. To reduce the costs of logistics and assembly, the assembly parts are already in the as-delivered condition with fasteners stocked. So while transport the fasteners, z. As screws, not from the mounting part fall off and get lost, fastener and mounting part are captive connected with each other. The fastener is in the through hole of the Mounting parts axially movable held so that, for example, gravity conditionally movable in an axial position, in which its fixing section from the side facing away from the head of the mounting part, the mounting side, Completely or at least so far protruding that the desired screwing is guaranteed. When placing the mounting part with its mounting side on a Basic construction, which is usually done with the help of a robot, the fixing sections are possible Completely in the through holes pushed back. A damage the cooperating with the mounting side mounting surface of the Basic construction or the fixing sections is thereby avoided. However, the fixation sections projecting from the mounting side can while the approach of the mounting part to the counter surface to disturb, For example, on edges of the basic structure or surveys the counter surface hang stay.
Aufgabe der Erfindung ist es, eine Montageeinheit und eine Befestigereinheit vorzuschlagen, welche die Handhabung eines an einem Maschinenteil zu fixierenden Montageteils vereinfachen.task The invention is an assembly unit and a fastener unit to suggest what the handling of a machine part Simplify the mounting part to be fixed.
Diese Aufgabe wird hinsichtlich einer Montageeinheit nach Anspruch 1 und hinsichtlich einer Befestigereinheit nach Anspruch 9 gelöst. Bei einer erfindungsgemäßen Montageeinheit steht zwischen Kopf und Fixierabschnitt ein erstes Halteelement aus der Schaftumfangsfläche des Befestigers radial nach außen und von der Wand der Durchgangsöffnung ein zweites Halteelement radial nach innen vor, wobei letzteres das erste Halteelement auf seiner dem Fixierabschnitt zugewandten Seite unter Ausbildung eines Hinterschnitts hintergreift. Die Axialposition der Haltelemente ist so gewählt, dass zumindest ein Teil des Fixierabschnitts innerhalb der Durchgangsöffnung angeordnet ist. Weiterhin sind die Halteelemente elastisch und/oder plastisch derart verformbar, dass bei einer Beaufschlagung des Befestigers mit einer zum Fixierabschnitt gerichteten Axialkraft der Hinterschnitt überwunden wird und das erste Halteelement das zweite Halteelement passiert. Je nach Bedarf kann der Überstand des Fixierabschnitts während der Montage verringert oder vollständig vermieden werden, wodurch die Montage erleichtert wird. Durch die plastische und/oder elastische Verformbarkeit zumindest eines der genannten Halteelemente kann die axiale Arretierung des Befestigers durch relativ geringen Kraftaufwand aufgehoben und die Befestiger mit ihren Fixierabschnitten z. B. in ein Muttergewinde der Grundkonstruktion eingedreht werden. Die erforderliche Kraft kann rieben einer Beaufschlagung des Befestigers in Axialrichtung mit einem Werkzeug auch dadurch aufgebracht werden, dass ein aus der Montageseite herausragender Gewindeüberstand in ein Muttergewinde eingeschraubt und dabei das erste Halteelement am zweiten Halteelement vorbei bewegt wird.These Task is with regard to a mounting unit according to claim 1 and solved with respect to a fastener unit according to claim 9. at an assembly unit according to the invention stands between the head and fixing a first holding element from the shaft peripheral surface of the fastener radially outward and from the wall of the through hole a second holding element radially inwardly, the latter the first holding element facing on its the fixing Engages behind page under formation of an undercut. The axial position the holding elements is chosen in that at least a part of the fixing section is arranged inside the passage opening is. Furthermore, the holding elements are elastic and / or plastic deformable such that upon exposure of the fastener overcome with an axial force directed to the fixing section of the undercut is and the first holding element passes the second holding element. According to need, the supernatant of the fixing section during the assembly can be reduced or completely avoided the assembly is facilitated. By the plastic and / or elastic Deformability of at least one of said holding elements can the axial locking of the fastener by relatively little effort lifted and the fasteners with their fixing z. B. be screwed into a nut thread of the basic construction. The Required force may rub an application of the fastener in the axial direction with a tool also be applied by that an outstanding from the mounting side thread overhang screwed into a nut thread while the first holding element is moved past the second holding element.
Weitere vorteilhafte Ausgestaltungen sind in den Unteransprüchen 2 bis 8 angegeben.Further advantageous embodiments are in the dependent claims 2 to 8 indicated.
Bei der Befestigereinheit nach Anspruch 9 wird die oben erwähnte Aufgabe prinzipiell auf die gleiche Art und Weise gelöst wie bei der beschriebenen Montageeinheit, sofern eine solche mit Befestiger und Hülse umfassenden Befestigereinheiten bestückt wird. Das zweite Halteelement ist dabei an der Wand der Hülse vorhanden, welche in einer Bohrung des Montageteils einliegt.at The fastener unit according to claim 9 becomes the above-mentioned object in principle solved in the same way as in the described Mounting unit, if one with fastener and sleeve comprehensive Fastener units equipped becomes. The second holding element is present on the wall of the sleeve, which rests in a bore of the mounting part.
