Description

Die Erfindung bezeichnet ein zumindest teilweise schlagendes Elektrohandwerkzeuggerät gemäß dem Oberbegriff des Anspruchs 1, das aus dem Dokument WO 8 806 508 A bekannt ist, bspw. einen Bohrhammer oder einen Meisselhammer, mit Leerschlagabschaltung eines pneumatischen Schlagwerks.The invention refers to an at least partially striking electric hand tool device according to the preamble of claim 1, which is known from the document WO 8 806 508 A is known, For example, a hammer drill or a chisel hammer, with Leerschlagabschaltung a pneumatic impact mechanism.

Elektrohandwerkzeuggeräte mit pneumatischem Schlagwerk benutzen zur Erzeugung des Schlages eine hin- und hergehende schwingende Bewegung, welche auf eine Gasfeder zwischen einem in einem Hohlzylinder dichtend relativ zu diesem beweglichen Erregerkolben und einem distanzierten, in Richtung der Werkzeugachse dichtend beweglichen, Flugkolben aufgebracht wird, welcher über einen Döpper axial auf das Werkzeug schlägt. Der Schlag wird vorteilhaft bei fehlendem Gegendruck auf das in einer Werkzeugaufnahme axial begrenzt bewegliche Werkzeug über eine Leerschlagabschaltung unterbrochen.Electric hand tools with pneumatic percussion use to generate the Beat a reciprocating swinging motion, pointing to a gas spring between one in a hollow cylinder sealing relative to this movable exciter piston and a distanced, in the direction of the tool axis sealingly movable, air piston is applied, which beats axially via an anvil on the tool. The punch is advantageous in the absence of back pressure on the in a tool holder axially limited movable tool interrupted by a space switch.

Nach der EP759341A3 wird bei Einnahme einer, durch eine Leerwegvergrösserung ermöglichten, Leerschlagposition des Döppers, zur Leerschlagabschaltung die Gasfeder über gesteuerte Ventile zur Umgebung belüftet und somit eine den Schlag erzeugende Druckdifferenz verhindert. Nachteilig bei einer derartigen Lösung sind die dazu erforderlichen Ventile und die Ventilsteuerung.According to EP759341A3, taking in, by a Leerwegvergrösserung enabled, Discharge position of the striker, for idle stop the gas spring over controlled valves vented to the environment and thus a pressure difference generating the impact prevented. The disadvantage of such a solution are the valves required for this purpose and the valve control.

Nach der WO88/06508 wird zur Leerschlagabschaltung der Antrieb des Schlagwerkes automatisch über eine Kupplung unterbrochen, wenn das Werkzeug eine axiale Leerschlagposition einnimmt, welche mit einem Sensor gemessen und mit einer Kontrolleinheit ausgewertet wird. Nachteilig bei einer derartigen Lösung ist die dazu erforderliche Kupplung.According to WO88 / 06508, the drive of the percussion mechanism is used for blank stop automatically interrupted by a clutch when the tool has an axial blanking position which is measured with a sensor and with a control unit is evaluated. The disadvantage of such a solution is the required coupling.

Es ist die Aufgabe dieser Erfindung, eine einfache Lösung zur Leerschlagabschaltung eines zumindest teilweise schlagenden Elektrohandwerkzeuggerätes aufzuzeigen.It is the object of this invention to provide a simple solution for blanking of a show at least partially beating electric hand tool device.

Die Aufgabe wird durch die Merkmale des unabhängigen Anspruchs gelöst. Vorteilhafte Weiterbildungen ergeben sich aus den Unteransprüchen.The object is solved by the features of the independent claim. Advantageous developments emerge from the subclaims.

Im wesentlichen wird die axiale Position von dem Werkzeug, dem Döpper bzw. dem Schlagwerk mit einem Sensor abgetastet und diese Information mit einer Kontrolleinheit ausgewertet, welche im Falle eines Leerschlags die Drehzahl des Erregerantriebs auf eine vorher festgelegte Drehzahl absenkt. Somit greift die Erfindung nach dem Verursacherprinzip bei der für Leerschläge ursächlichen, konstant bleibenden Drehzahl des Erregerantriebs an. Bei einer hinreichend abgesenkten Drehzahl des Erregerantriebs bildet sich bedingt durch Belüftungsöffnungen keine den Flugkolben beschleunigende Druckdifferenz mehr aus, wodurch keine weiteren Schläge auf den Döpper und das Werkzeug erzeugt werden. Dazu wird die Drehzahl des Erregerantriebs auf 10% bis 50% der Arbeitsdrehzahl reduziert.In essence, the axial position of the tool, the striker or the Schlagwerk scanned with a sensor and this information with a control unit evaluated, which in the case of a blank, the speed of the exciter drive to a previously set speed lowers. Thus, the invention uses the polluter pays principle at the causal for vacancies, constant speed of the exciter drive on. At a sufficiently lowered speed of the exciter drive forms due Vents no more pressure on the fly piston accelerating pressure, whereby no further blows to the striker and the tool are generated. To The speed of the exciter drive is reduced to 10% to 50% of the working speed.

Vorteilhaft ist der Sensor als induktiver oder kapazitiver Sensor ausgeführt, welcher direkt auf die axiale Position von dem Werkzeug, dem Döpper bzw. dem Schlagwerk anspricht.Advantageously, the sensor is designed as an inductive or capacitive sensor, which directly responds to the axial position of the tool, the striker or percussion.

Alternativ ist der Sensor als Hall-Sensor ausgeführt, welcher einem relativ zu diesem bewegbaren Magneten zugeordnet ist, der mit einem die axiale Position von dem Werkzeug, dem Döpper bzw. dem Schlagwerk abgreifenden Stellglied verbunden ist.Alternatively, the sensor is designed as a Hall sensor, which is a relative to this associated with a movable magnet having an axial position of the tool, connected to the striker or the percussion actuator.

Dieses Stellglied ist vorteilhaft gabelförmig axial in den Döpper eingreifend ausgeführt, und am äusseren Umfang des Döppers, bspw. mit einem leichten Aluminiumring, befestigt. Das vorteilhaft aus leichtem, hochsteifem faserverstärkten Kunststoff bestehende Stellglied weist einen kleinen Magneten auf, der sich zusammen mit dem Döpper an dem Hall-Sensor vorbei bewegt.This actuator is advantageously executed forked engaging axially in the striker, and on the outer circumference of the bonnet, for example, with a light aluminum ring attached. The advantageous from lightweight, highly rigid fiber-reinforced plastic existing actuator has a small magnet, which passes along with the striker at the Hall sensor emotional.

Vorteilhaft ist der Erregerantrieb als Elektromotor ausgeführt, dessen Motordrehzahl von der Kontrolleinheit über die Motorelektronik elektronisch herabsetzbar ist.Advantageously, the exciter drive is designed as an electric motor whose engine speed of the Control unit via the engine electronics electronically herabsetzbar is.

Vorteilhaft wird der Erregerantrieb und ein optionaler Drehantrieb über ein Getriebe von einem gemeinsamen Elektromotor abgeleitet, wodurch bei einem Leerschlag ebenfalls die Drehzahl einer optionalen Drehbewegung herabgesetzt wird.Advantageously, the exciter drive and an optional rotary drive via a transmission of derived from a common electric motor, whereby at a space also the Speed of an optional rotational movement is reduced.
