Abstract

A tool for accurate insertion of hollow screw fasteners has a sprung drive with bearing support inside a fixed mounting and with a sensor for determining the insertion depth of the fastener. The tool can be powered manually or by servo force.

Description

Angetriebene Schraubwerkzeuge üblicher Bauart weisen keine oder eine aus dem Drehmoment/ Drehwinkel abgeleitete Abschaltung auf. Diese werden mit Strom oder Druckluft betrieben.driven Screwing tools of conventional design have no or one derived from the torque / angle of rotation Shutdown on. These are powered by electricity or compressed air.

In jedem Fall jedoch ist ein derartiges einstellendes (definiertes Drehmoment) Verschrauben mit dieser Art Schraubwerkzeug nicht möglich, wenn das zu verschraubende Produkt und oder die Schraube selber aufgrund ihrer Beschaffenheit keine Drehmoment- und/oder Winkelgröße zur definierten Verschraubung zur Verfügung stellt. Ein Beispiel wären Kunststoffkomponenten, die derart instabil aufgebaut sind oder sich nur instabil für die Verschraubung fixieren lassen.In In any case, however, such an adjusting (defined Torque) Screwing with this type of screwing tool not possible, if the product to be screwed and / or the screw itself due their nature no torque and / or angle size to the defined Screw connection available provides. An example would be plastic components, which are built so unstable or only unstable for the screwing let fix.

Ein konkretes Beispiel für diesen Fall (Drehmoment und/oder Winkel sind nicht verwendbar) ist die Anlageschraube, auch Hohlschraube genannt, die der Scheinwerfereinstellung dient. Diese Hohlschraube, welche direkt in Laschen des Kfz-Scheinwerfers eingeschraubt wird, ist nur eine Distanzeinstellung, damit der Scheinwerfer korrekt im Fahrzeug eingebaut werden kann. Worauf es bei dieser Verschraubung ankommt, ist die exakte Einschraubtiefe, welche unabhängig von Schraubenlänge, Drehmoment und der Position des Scheinwerfers in seinem Halter wiederholgenau erfolgen kann.One concrete example for this case (torque and / or angle are not usable) is the Anlageschraube, also known as hollow screw, the headlamp setting serves. This banjo bolt, which directly in tabs of the car headlight is screwed in, is only a distance adjustment, so that the headlight can be installed correctly in the vehicle. What about this Fastening arrives, is the exact screwing, which regardless of Screw length, Torque and the position of the headlamp in his holder repeatable can be done.

Der im Schutzanspruch 1 angegebenen Erfindung liegt das Problem zugrunde, ein Schraubgerät zu schaffen, welches nur die Einschraubdifferenz (Schraubenfläche zu Bauteilträger) als Abschaltkriterium verwendet. Dies schließt den Einfluss von Bauteilwerkstofftoleranzen und Drehmomenttoleranzen weitgehend aus.Of the in claim 1 protection invention is based on the problem a screwdriver to create, which only the Einschraubdifferenz (screw surface to component carrier) as Switch-off criterion used. This excludes the influence of component material tolerances and torque tolerances largely off.

Mit der Erfindung wird erreicht, dass die Schraubenlängentoleranzen aufgrund der Differenzmessung (Schutzanspruch 2) der Einschraubtiefe (kein Absolutwert) keinen Einfluss auf das Verschraubungsendergebnis haben.With the invention is achieved that the screw length tolerances due to Differential measurement (protection claim 2) of the screw-in depth (no absolute value) have no influence on the tightening result.

Eine weitere Ausgestaltung der Erfindung ist im Schutzanspruch 1 dargestellt. Der Abtrieb (die Schraubnuss) ist federnd gelagert. Im Gegensatz zu handelsüblichen federnden Abtrieben (einfache Vielkeilwellen), ist dieser kugelgelagert und kann bei aufgebrachtem Drehmoment der Schraube folgen.A Another embodiment of the invention is shown in the protection claim 1. The output (the screw nut) is spring-mounted. In contrast to commercially available resilient drives (simple splined shafts), this is ball bearing and can follow the screw with torque applied.

Ein Ausführungsbeispiel der Erfindung wird anhand der 1 bis 4 erläutert. Diese zeigen:An embodiment of the invention will be described with reference to 1 to 4 explained. These show:

1 den gesamten Aufbau des Schraubgerätes 1 the entire structure of the screwdriver

2 den Sensor (Schraubenlängendifferenzmessung) mit Abtrieb, Stößel und Wandler. 2 the sensor (screw length difference measurement) with output, ram and converter.

3 das kugelgelagerte Abtriebinnenteil, 3 the ball-bearing driven inner part,

4 den Kugelgegenlagerantrieb 4 the ball bearing drive

In den Figuren ist der Schrauber mit federnd-kugelgelagertem Abtrieb (1 Pos 3 + 5) und dem Sensor, bestehend aus Stößel und Wandler (2 Pos 2 + 7), dargestellt.In the figures, the screwdriver with spring-ball-supported output ( 1 Pos 3 + 5 ) and the sensor, consisting of plunger and transducer ( 2 Pos 2 + 7 ).

Prozess: Während die Schraube zugestellt wird, ändert sich der Abstand zwischen dem Schraubenkopf (der Schraube bzw. der Nuss 1 Pos.2) und dem darunter positioniertem Bauteilträger. Die Folge daraus ist, dass sich der Stößel (2 Pos.1) in den Wandler (2 Pos.7) bewegt und eine Tiefenänderung feststellt. Mit jeder festgestellten Tiefenänderung wird der aufgenommene Einschraubwinkel der Schraube wieder zurückgesetzt. Liegt die Schraube an dem Bauteilträger an, so ergibt sich keine Tiefenänderung des Stößels mehr und der Schraubenwinkel steigt bis zu einem fest vorgegebenen Wert an. Die Anlage der Schraube am Bauteilträger ist damit erreicht. Um einen definieren Anlagepunkt zu erreichen, kann der Schrauber die Schraube wieder um einen ebenfalls definierten Winkel zurückdrehen.Process: While the screw is being delivered, the distance between the screw head (the screw or the nut) changes 1 Pos. 2 ) and the component carrier positioned underneath. The consequence of this is that the plunger ( 2 Pos. 1 ) in the converter ( 2 Pos. 7 ) and detects a change in depth. With each depth change detected, the recorded screw-in angle of the screw is reset. If the screw on the component carrier, so there is no change in depth of the plunger and the screw angle increases up to a fixed predetermined value. The installation of the screw on the component carrier is thus achieved. To achieve a defined point of attachment, the screwdriver can turn back the screw by a likewise defined angle.
