具体实施方式
图1示出示例性的手持式工具机100,该手持式工具机具有带有手柄115的工具壳体105。根据一种实施方式,手持式工具机100为了实现与电网无关的供电而能机械地和电地与蓄电池组190相连接。在图1中,手持式工具机100示例性地设计为电动钻孔机(Akku-Bohrschrauber)。然而需要指出的是,即本发明不限于电动钻孔机,而是更确切地说可以应用在各种不同的手持式工具机中,在这些手持式工具机中,工具可以置于旋转状态,而不取决于手持式工具机是能够与依赖电网进行驱动或与电网无关地利用蓄电池组190进行驱动,例如可以应用在螺丝刀或蓄电池螺丝刀(Akku-Schrauber)、冲击式螺丝刀或蓄电池冲击式螺丝刀(Akku-Schlagschrauber)、冲击钻或者说锤式钻孔机(Schlagbohrmaschine)或蓄电池冲击钻或者说蓄电池锤式钻孔机(Akku-Schlagbohrmaschine)中。
在工具壳体105中布置有由蓄电池组190供电的、电动的驱动电机180和传动装置109。驱动电机180通过传动装置109与驱动轴120、例如驱动主轴相连接。在手持式工具机100运行时,电机180通过传动装置109旋转地对驱动轴120进行驱动。
驱动电机180示范性地布置在电机壳体185中并且传动装置109布置在传动装置壳体110中,其中传动装置壳体110和电机壳体185示例性地布置在工具壳体105中。传动装置109配备有用于容纳工具150的工具容纳部140,该工具容纳部例如具有转接头145。工具容纳部140可以形成到可由驱动电机180通过传动装置109驱动的驱动轴120上或者以套装的形式与该驱动轴相连接。
转接头145示范性地具有操纵套管149和用于容纳所谓的HEX-钻头或螺丝刀钻头的六边形内容纳部147。适合的HEX-钻头和螺丝刀钻头是那些具有带有至少部分的呈六角形的横截面的杆的工具,该杆在HEX-钻头中配有环形槽。此外,转接头145也可以或者对此可替换地设计用于容纳所谓的SDS-快速迷你-钻机工具。对此合适的SDS-快速迷你-钻机工具是那些具有基本上呈圆柱形的杆的钻机工具,该杆具有两个平行于杆的纵轴线而凸出的旋转带动连接片,该旋转带动连接片分别具有锁定凹部。这种工具以及适合的转接头的结构和工作原理对于本领域技术人员而言是充分已知的,例如由DE 20 2007 010 699 U1已知,其公开内容明确地包含在本说明中,从而在此出于说明简洁的目的而可以省略对这些组件的详细说明。
驱动电机180例如可通过手动开关195接通和断开并且可以是任意的电机类型,例如是电子换向的电机或者直流电机。优选地,驱动电机180可这样电子地控制或者说调节,即不仅可逆运行、而且在期望的旋转速度方面的预先规定都是可实现的。适合的驱动电机的工作原理和结构是由现有技术充分已知的,从而在此出于说明简洁的目的而省略详细的说明。
传动装置109例如可以根据减速传动装置的类型设计,其例如可利用设计有不同的行星级的行星齿轮装置来实现,该行星齿轮装置备选地配备有扭矩离合器199。扭矩离合器199设计用于,如果由驱动轴120传递到传动装置109上的扭矩超过了可由手持式工具机100的使用者调节的阈值,则在手持式工具机100运行时阻止通过传动装置109对驱动轴120进行驱动。此外,手持式工具机100可以具有其它组件、例如机械的或气动的撞锤等等。然而需要指出的是,具有配备的扭矩离合器的、适合的传动装置的设计方案以及机械的和气动的撞锤和其工作原理对于本领域技术人员而言是充分已知的,从而在此出于说明简洁和附图简单的目的而省略对此的图示和详细的说明。
根据一种实施方式,手持式工具机100或工具容纳部140配备有固定单元170,该固定单元示范性地轴向和径向不能运动地固定在工具壳体105上。该固定单元示例性地设计为套管形并且因此在下面也称为“固定套管”。然而需要指出的是,固定套管170仅仅示例性地设计为一个单独的部件并且替代于此也可以与工具壳体105一体构成。
固定套管170用作用于配备的工具附件(图2中的200)的锁定和定心装置并且至少部分地以预设的径向间隔包覆转接头145,以便能实现转接头145的操纵套管149在固定套管170的内部轴向地移动。在固定套管170的内周179上示范性地设有彼此间隔的、连接片形式的突起部,该突起部沿固定套管170的纵向方向延伸并且径向向内对准,以及在这些突起部中出于附图简明和清楚的目的仅示出了两个带有附图标记171的突起部。在这些连接片形式的突起部之间示范性地设有槽形的凹部,在这些凹部中出于附图简明和清楚的目的仅示出了两个带有附图标记178的凹部。这些凹部178例如可以设计为在连接片形式的突起部之间的间隙或者按照固定套管170的内周179上的凹陷的形式设计。
根据一种实施方式,固定套管170具有外周173,该外周在环形肩部172处在背离工具壳体105的、缩小的区域176中变细。在这个缩小的区域176中,在外周173上设有至少一个并且优选多个板形的控制元件。这些控制元件示范性地按照直角梯形的形式设计并且分别具有配属的、斜切的引导棱。出于附图简明和清楚的目的,仅示出了两个带有附图标记174的控制元件以及仅示出了两个带有附图标记175的引导棱。
图2示出了工具系统205,具有根据图1的手持式工具机100和固定在其上的、示例性的工具附件200。该工具附件示范性地按照偏心附件的形式来设计并且设计用于固定在手持式工具机100的固定套管170上。固定套管在其外周173上具有两个示范性的板形的控制元件274、276,其中控制元件276示例性地具有引导棱277。控制元件274、276代表了根据图1的控制元件174。
根据一种实施方式,工具附件200具有设计用于锁定和定心的锁定部段210以及在后面也称为“偏心驱动部段”的驱动单元250。锁定部段210示范性地具有基体300,该基体形成用于容纳转接头145的内部空腔315并且在其外周350上一方面形成了防旋转单元330并且另一方面可旋转运动地以及优选地不可轴向移动地布置有锁定套管400。防旋转单元330设计用于防转转地将基体300固定在手持式工具机100的固定单元170上。锁定套管400用于释放或锁定至少一个配属的锁定元件420,该锁定元件示范性地按照沿锁定套管400的圆周方向定向的锁定连接片的形式设计在锁定套管400的内周405上。
根据一种实施方式,防旋转单元330以下述方式设计在背离偏心驱动部段250的、基体300的外周350的轴向的端部区域中,使得防旋转单元330和手持式工具机100的固定单元170具有互补的几何形状,该形状适合于形成形状配合的连接,并且对此设计成为了可拆卸地、防转转地将基体300固定在固定单元170上而交错地接合。相应地,防旋转单元330示范性地具有至少一个连接片形式的突起部,该突起部在外周350上沿基体300的纵向方向延伸,其中,在图2中示例性地可以看到两个突起部332、340。在这些连接片形式的突起部332、340之间例如设计有槽形的凹部,如下面在图3中描述。这些凹部例如可以设计为在连接片形式的突起部332、340之间的间隙或者按照外周350上的凹陷的形式设计。示范性地,连接片形式的突起部332、340和槽形的凹部延伸到设计在外周350上的、环形的突出部320,环形肩部410抵靠在其朝向偏心驱动部段250的侧面上,该环形肩部设计在锁定套管400的内周405上。
环形肩部410在基体300的外周350上至少基本上不能运动地布置在环形的突出部320和示范性地布置在基体300的环形槽312中的固定环216之间。在固定环216的区域中,环形肩部410示例性地具有斜切的边棱499。
示范性地,锁定套管400由弹簧元件500、例如扭转弹簧加载了预设的弹簧力,以用于实现可拆卸地、防转转地将基体300固定在固定单元170上,并沿箭头298的方向到达锁定位置中,其中,锁定位置对应于锁定套管400的第一旋转位置。扭转弹簧500示例性地布置在环形肩部410和配属于偏心驱动部段250的壳体部段252的端面241之间。
根据一种实施方式,偏心驱动部段250具有偏心传动装置260,该偏心传动装置具有例如配有六边形内容纳部的从动轴268,以用于驱动工具、例如根据图1的工具150。其示范性地可旋转地支承在壳体部段252中,该壳体部段示例性地在其端面241的区域中具有径向向内的环形凸缘249,该环形凸缘固定在配属的、设置在基体300的外周350上的环形槽310中,使得壳体部段252至少轴向不能运动地固定在基体300上。从动轴268可由从动轮266旋转,该从动轮可由与驱动轴262耦合的驱动轮264来驱动。驱动轴262沿轴向的方向看至少在一侧可旋转地支承在壳体部段252上并且优选地至少可以与转接头的内容纳部、例如根据图1的转接头145的六边形内容纳部147相连接。
然而需要指出的是,即适合的偏心驱动部段以及偏心传动装置对应本领域技术人员而言是充分已知的。因此出于说明简洁的目的而省略对这些组件的详细说明。
为了将工具附件200固定在手持式工具机100的固定套管170上,将其基体300沿箭头297的方向推到固定套管170上。在此,朝向固定套管170的、空腔315的轴向端部区域首先通过固定套管170定位和定心,并且将朝向根据图1的转接头145的内容纳部147的、驱动轴262的轴向端部插入到其中。通过进一步沿箭头297的方向移动工具附件200,随后防旋转单元330的连接片形式的突起部332、340则与固定套管170的对应的、槽形的凹部178接合,并且固定套管170的连接片形式的突起部(图1中的171)则与防旋转单元330的配属的、槽形的凹部(图3中的390)接合。在此,锁定连接片420示范性地与控制元件276的引导棱277接触。与此类似地,其它锁定连接片(例如图4中的422、424、426)与附加的控制元件(例如图1中的174)或者其引导棱(例如图1中的175)接触。
在进一步沿箭头297的方向移动工具附件200时,则实现了锁定连接片420沿引导棱277 的相切的移动。在此,通过锁定连接片420产生了对锁定套管400的力作用,其导致了锁定套管400克服弹簧元件500的弹簧力沿箭头299的方向从对应的锁定位置进入到对应的释放位置中的旋转运动,该释放位置则对应于锁定套管400的配属的第二旋转位置。
当锁定连接片通过工具附件200沿箭头297的方向移动而到达控制元件276的轴向端部区域并且锁定套管400因此一方面已经到达了轴向端部位置并且另一方面已经到达了释放位置时,锁定连接片420的相切的移动结束。在那里,锁定套管400沿箭头298的方向基于扭转弹簧500的弹簧力而旋转,该扭转弹簧如上述将锁定套管400加载到其锁定位置中,这是因为这种扭转现在不再由抵靠在引导棱277上的锁定连接片420锁定。在此,锁定连接片420示范性地在一形成在控制元件276和设置在固定套管170的外周173上的环形肩部172之间的自由区域中运动并且因此沿工具附件200的轴向方向看在后接合控制元件276,使得由此实现了锁定套管400在固定套管170上的轴向锁定。
基体300和进而工具附件200相应地可拆卸地锁定在手持式工具机100的固定单元170上,而为此不需要通过使用者来手动扭转锁定套管400。因此可以以舒适的方式和方法通过使用者的一只手来将工具附件200安装在手持式工具机100上。在此,基体300为了对扭矩产生支持而借助于防旋转单元330防转转地在固定单元170上固定和定心。
根据一种实施方式,基体300在固定单元170上的可拆卸的、防转转的固定通过解锁锁定套管400而是可拆卸的,其可以通过沿箭头299的方向手动地扭转锁定套管400而克服扭转弹簧500的弹簧力从锁定位置到达相应的释放位置中。在此,控制元件276的在后接合通过锁定连接片420而取消,使得工具附件200可以反向于方向297轴向移动,以用于将工具附件200从手持式工具机100上拆卸或移除。
图3示出了根据图2的工具附件200的基体300,其具有防旋转单元330,用于表明在其外周350上形成的环形槽310、312、环形的突出部320以及根据图2的连接片形式的突起部332、340。此外,在外周350上,在防旋转单元330的区域中示范性地示出了其它连接片形式的突起部334、336、338、342,以及槽形的凹部,其例如形成在突起部332、334、336、338、340、342之间,然而替代于此也可以设计为在外周350上的凹部。出于附图简洁和简单的目的而仅仅示出了两个带有附图标记390 的槽形的凹部。
图4示出了根据图2的工具附件200的锁定套管400,其具有形状在其内周405上的环形肩部410,在该环形肩部上设置了斜切的边棱499;以及锁定连接片420。此外,在内周405上示范性地示出了其它锁定连接片,在这些锁定连接片中出于附图简洁和简单的目的而仅示出了三个带有附图标记422、424、426的锁定连接片。
根据一种实施方式,在环形肩部410的区域中还设有槽形的容纳部430。该容纳部例如用于容纳根据图3的扭转弹簧500的端部区域(图5中的510),以便因此能描述如根据图2中的锁定套管400的弹簧加载。
