HandwerkzeugmaschineHand tool
Stand der TechnikState of the art
Die Erfindung geht aus von einer Handwerkzeugmaschine nach dem Oberbegriff des Anspruchs 1.The invention is based on a hand tool according to the preamble of claim 1.
Es sind Handwerkzeugmaschinen, insbesondere Handbohrmaschinen und Bohrhämmer mit Gehäusen in Topfbauweise mit einem am Ende des zylindrischen Gehäuses angeordneten Verschlußdeckel bekannt. Dieser Deckel ist jedoch nur umständlich unter Zuhilfenahme von gesonderten Werkzeugen zu öffnen, wobei er nicht oder nur sehr bedingt als Servicedeckel zum Wechseln der Kohlbürsten geeignet ist. Außerdem ist der bekannte Deckel nicht gegen Verlieren am Gehäuse sicherbar.Hand-held power tools, in particular hand drills and rotary hammers with housings in pot construction with a closure cover arranged at the end of the cylindrical housing, are known. However, this lid can only be opened with great difficulty with the aid of separate tools, and it is not suitable, or only to a very limited extent, as a service lid for changing the cabbage brushes. In addition, the known cover cannot be secured against loss on the housing.

Beschreibung des AusführungsbeispielsDescription of the embodiment
Figur 1 zeigt eine räumliche Darstellung einer als Bohrhammer ausgestalteten Handwerkzeugmaschine 10 in der Ansicht von links vorn. Die Handwerkzeugmaschine hat ein Gehäuse 12, das aus einer linken und rechten längsgeteilten Gehäuseschale 121, 122 mit einem als Spatengriff ausgestalteten Hand- griff 14, der eine Schalttaste 16 enthält, aus der nach unten ein E-Kabel 18 zur Energieversorung des nichtdargestell- ten, im Inneren eines zum Gehäuse 12 gehörenden Motor-Gehäuse 20 angeordneten Motors austritt. Das Motor-Gehäuse 20 ist einstückig mit den Gehäuseschalen 121, 122 in Motorgehäuse- schalen 201, 202 geteilt, die gegenüber einer Längsachse 27 der Handwerkzeugmaschine 10 rechtwinklig abgewinkelt angeordnet sind. Die Längsachse 27 ist durch einen Maschinenhals 22, ein Spannfutter 24 und ein als Bohrer ausgestaltetes Einsatzwerkzeug 26 definiert.FIG. 1 shows a spatial representation of a handheld power tool 10 designed as a hammer drill in the view from the front left. The handheld power tool has a housing 12, which consists of a left and right longitudinally divided housing shell 121, 122 with a handle 14 designed as a spade handle, which contains a switch button 16, from which an E-cable 18 for energy supply of the not shown, emerges inside a motor housing 20 belonging to the housing 12. The motor housing 20 is divided in one piece with the housing shells 121, 122 into motor housing shells 201, 202, which are arranged at right angles to a longitudinal axis 27 of the handheld power tool 10. The longitudinal axis 27 is defined by a machine neck 22, a chuck 24 and an insert tool 26 designed as a drill.
Ebenfalls rechtwinklig nach unten tritt ein Zusatzhandgriff 28 von der Längsachse 27 weg, der am Maschinenhals 22 mittels eines Spannbandes 30 abnehmbar gehaltert ist. Der Zusatzhandgriff 28 enthält einen oberen Fortsatz 29 mit einer konkaven, der zur Anlage an den Maschinenhals 22 bestimmt ist und dem Zusatzhandgriff 29 einen sicheren Halt am Gehäuse 12 gibt.An additional handle 28 also extends downward at right angles from the longitudinal axis 27 and is removably held on the machine neck 22 by means of a tensioning strap 30. The additional handle 28 contains an upper extension 29 with a concave, which is intended to bear against the machine neck 22 and gives the additional handle 29 a secure hold on the housing 12.
Beiderseits der konkaven, radialen Abstützflache 40 bildet der obere Fortsatz 29 - in Betrachtungsrichtung von vorn - zwei Schenkel, von denen nur der größere Tragschenkel 31 näher bezeichnet ist. Darin ist ein als Sechskantstab aus- gestalteter Tiefenanschlag 32 drehgesichert längsverschiebbar in einer als Sechskantbohrung ausgestalteten Längsführung 38 gelagert. Der Tiefenanschlag 32 hat an gegenüberliegenden Sechkantflächen ein oberes und ein unteres Zahnprofil 34, 35 mit dem er sich formschlüssig in der Längsführung 38 lösbar festhält.On both sides of the concave, radial support surface 40, the upper extension 29 forms two legs, viewed from the front, of which only the larger supporting leg 31 is specified. In it, a depth stop 32 designed as a hexagonal rod is secured against rotation in a longitudinally displaceable manner in a longitudinal guide 38 designed as a hexagonal bore. The depth stop 32 has an upper and a lower tooth profile 34, 35 on opposite hexagonal surfaces with which it is releasably retained in the longitudinal guide 38 in a form-fitting manner.
Figur 2 zeit ausschnittsweise den unteren Bereich des Motorgehäuses 20, wobei dieses von einem Klappdeckel 60 stirnseitig verscchlossen ist. Dieser Klappdeckel 60 ist in der linken Gehäuseschale 121 in dem Schraubdom 64 gelenkig gelagert. Der Klappdeckel 60 deckt die untere Hälfte des Motorgehäuses 20 im Bereich der Kohlebürsten ab. Über eine Sicherungsschraube 66 wird der Klappdeckel 60 am Motorgehäuse 20 zur betriebsgemäßen Benutzung befestigt. Die Sicherungs- schraube 66 ist unverlierbar mit dem Klappdeckel 1 verbunden.FIG. 2 shows a section of the lower area of the motor housing 20, this being closed at the end by a hinged cover 60. This hinged cover 60 is articulated in the left housing shell 121 in the screw dome 64. The hinged cover 60 covers the lower half of the motor housing 20 in the area of the carbon brushes. The hinged cover 60 is fastened to the motor housing 20 for operational use by means of a securing screw 66. The locking screw 66 is captively connected to the hinged cover 1.
Durch das Aufschrauben der Sicherungsschraube 66 wird die Verbindung zwischen Motorgehäuse 20 und Klappdeckel 60 ge- löst. Der Klappdeckel kann weggeklappt werden ohne komplett vom Gerät entfernt zu werden müssen.By screwing on the locking screw 66, the connection between the motor housing 20 and the hinged cover 60 is released. The hinged lid can be folded away without having to be completely removed from the device.
Die Sicherungsschraube 66 kann mit einem Schraubendreher oder aber mit einem Schlüssel oder einer Münze gelöst wer- den. Das Wegklappen des Klappdeckels 60 ermöglicht einen einfachen und bequemen Kohlebürstenwechsel. Das Motorgehäuse 20 umgreift ein gesondertes Hüllgehäuse (Fig. 6) , das bei der Montage zwischen die Gehäuseschalen 121, 122 eingelegt wird. Dieses Hüllgehäuses 62 trägt am unteren Ende eine ra- dial nach außen weisende Gewindebohrung 68 zum Eingriff der Sicherungsschraube 66 und außerdem die Kohlbürsten für den Motor.The locking screw 66 can be loosened with a screwdriver or with a key or a coin. Folding away the hinged cover 60 enables one simple and convenient carbon brush change. The motor housing 20 encompasses a separate envelope housing (FIG. 6) which is inserted between the housing shells 121, 122 during assembly. This casing 62 carries at the lower end a radial outward-pointing threaded bore 68 for the engagement of the locking screw 66 and also the carbon brushes for the motor.
Die rechte Gehäuseschale 122 ist zweiteilig gestaltet. Sie trägt einen kleinen Deckel zur Inspektion der Netzleitung 18. Der Deckel ist mit zwei Schrauben am Gehäuse 12 befestigt. Nach dem Entfernen des Deckels kann das Netzkabel einfach ausgetauscht bzw. ersetzt werden.The right housing shell 122 is designed in two parts. It carries a small cover for inspecting the power line 18. The cover is fastened to the housing 12 with two screws. After removing the cover, the power cord can be easily replaced or replaced.
Dazu müssen die zwei Schrauben der Klemmleiste gelöst werden, um das Kabel von der Maschine zu entfernen. To do this, the two screws on the terminal block must be loosened to remove the cable from the machine.
