Description

钻机
技术领域
本发明涉及一种按权利要求1前序部分所述的钻机。
背景技术
这种钻机业已公知。在此,钻机具有扭矩离合器,所述扭矩离合器实现了将钻机尤其也用作起子机。在此,借助扭矩离合器将有待传递到螺栓上的扭矩限制在合理的范围内。公知的钻机为此具有由操作者操纵的调整环,所述调整环用来调整可传递的扭矩。用该调整环使布置在传动机构壳体上的调整螺母沿轴向运动,所述调整螺母尤其直接作用在轴向布置的压力弹簧上,所述压力弹簧又与能够沿轴向运动的离合器从动盘配合作用。在此,压力弹簧在传动机构壳体的螺纹段之间导引,调整螺母也设置在所述传动机构壳体上。
此外还已知的是,在一种冲击钻机中,布置在工具张紧单元的侧面上的、用于芯轴的轴承在冲击钻头工作时能够沿轴向移动,从而将轴承用作浮动轴承,因而可以将冲击装置作用到芯轴上。为此,通常设置一种沿轴向连接到扭矩离合器上的装置。
发明内容
基于所示现有技术,本发明所要解决的技术问题是,进一步发展一种按权利要求1前序部分所述的钻机,从而得到钻机的特别紧凑的轴向结构。该技术问题在一种具有权利要求1的特征的钻机中解决。在此,本发明基于这样一种思想,即,用来轴向推移用于芯轴的轴承的装置在局部至少部分地与用来调整扭矩离合器的扭矩的装置重叠。为此,按照本发明规定,用于推移轴向轴承的装置在朝向离合器从动盘的那一侧具有至少一个触发节段,所述触发节段设置在尤其设计成传动机构壳体的壳体结构元件的第二凹部中并且在朝向离合器从动盘的那一侧与用于所述用于推移轴向轴承的装置的调整元件配合作用。换而言之,这意味着,至少一个触发节段位于壳体构件的区域内,压力弹簧也布置在该区域中。
按本发明的钻机的有利的扩展设计在从属权利要求中说明。所有由至少两个在说明书、权利要求书和/或附图中公开的特征构成的组合都属于本发明范畴。
本发明的一种结构上特别有利的设计方案规定,所述装置具有多个过梁式的触发节段,这些节段以均匀的角距相互设置,以及第二凹部至少形状配合地容纳所述过梁式的触发节段。由此能够传递相对较高的轴向力,其中,通过导引触发节段附加地在侧向导引这些轴向力。
此外,为了容纳触发节段以实现轴向较短的结构长度,规定调整螺母具有大于已装配的压力弹簧的包络线的根圆直径,过梁式的触发节段沿径向于调整螺母的根圆直径之内延伸。
为了将轴向力从调整螺母传递到压力弹簧上,在本发明的一种结构性扩展设计中规定,调整螺母与弹簧架元件配合作用,所述弹簧架元件具有径向向内突伸且与压力弹簧配合作用的节段。
为了在将轴向力施加到压力弹簧上时避免压力弹簧侧向滑出,以及同时在压力弹簧之间实现到离合器从动盘的最佳的动力啮合,还有利地规定,向内突伸的节段具有销式的突出部,在所述突出部上分别导引压力弹簧,并且,在离合器从动盘上在与弹簧架元件对置的那一侧布置了传力器件尤其球体,其到芯轴的径向间距大致对应压力弹簧到芯轴的间距。
为了实现从调整螺母到离合器从动盘的特别良好的传力,从而特别是在冲击钻孔操作时闭锁离合器装置,在本发明的另一种设计方案中还规定,弹簧架元件在轴向方向上与调整螺母对准地具有至少一个支撑节段,该支撑节段为了轴向固定住离合器从动盘而贴靠在离合器从动盘上。
为了让所使用的构件数量保持得尽可能少以及因而在制造技术上实现钻机的最佳结构,还有利地规定,壳体构件是传动机构壳体。
在此,当该传动机构壳体设计成(例如由铝、镁或锌制成的)金属压铸件或设计成塑喷件时,可以在制造技术上相对有利地制造传动机构壳体。
附图说明
按本发明的钻机的其它优点由对优选实施例的下列说明以及借助附图得出。
附图中:
图1和图2示出了按本发明的钻机在不同剖切平面内的纵剖面的前部;
图3以立体视图表示传动机构壳体的前部;
图4示出了按图1和2的钻机在传动机构壳体区域内的横截面,以及
图5用立体图表示前部传动机构壳体的区域,其中,为清楚起见没有示出各种构件。
具体实施方式
在图1和2中示出了按本发明的钻机10的轴向前部。钻机10在此尤其设计成用蓄电池驱动的钻机10,并且具有冲击钻功能以及旋拧功能或钻孔功能。钻机10具有工具张紧装置11,其公知包括三个以沿径向均匀的角距彼此设置的夹头12。能够以公知方式打开和关闭夹头12,从而在夹头12之间容纳一个合适的工具,例如钻头或起子头。
工具张紧装置11固定在芯轴15的朝向该工具张紧装置的端部上。芯轴15的与工具张紧装置11对置的另一个端部设置成与离合器从动盘17作用连接,其中,离合器从动盘17设置成能沿轴向运动。离合器从动盘17是扭矩离合器18的组成部分,其包括多个例如六个球体19,这些球体以均匀的角距布置在离合器从动盘17的与工具张紧装置11对置的那一侧。球体19设置成与止动套筒21作用连接,该止动套筒与钻机10的尤其设计成多级的、优选设计成行星齿轮传动机构的传动机构20的从动轮连接。传动机构20又与钻机10的驱动电机(未示出)连接。
芯轴15在中间置入轴承的情况下被夹紧环22包围,所述夹紧环又被传动机构壳体24沿径向包围。为此,尤其由图1和图2可知,传动机构壳体24在其内侧具有缺口25,因此借助在通孔中穿过传动机构壳体24的固定螺栓26使传动机构壳体24能够与夹紧环22连接。此外还要提到的是,离合器从动盘17在传动机构壳体24中沿径向导引。
传动机构壳体24尤其设计成(例如用铝、镁或锌制成的)金属压铸件或塑喷件。借助图3至5清楚可知,传动机构壳体24在其朝向工具张紧装置11的端部上具有螺纹节段27,所述螺纹节段具有三个以均匀的角距彼此设置的螺纹过梁28。螺纹过梁28用其外螺纹29来固定或沿轴向导引调整螺母30(见图1、2和4)。调整螺母30同样是扭矩离合器18的组成部分并且与调整环32配合作用或能够由该调整环触发。如图3至5清楚可知,传动机构壳体24具有沿传动机构壳体24的纵向延伸的第一凹部33,在该第一凹部中以均匀的角距尤其布置了与球体19的数量对应个数的压力弹簧35,在本实施例中是六个压力弹簧35。有利的是,这样布置压力弹簧35和球体19,使它们在扭矩离合器18的止动套筒21没有滑转时相互对准。在此,压力弹簧35从径向看全部在传动机构壳体24的外螺纹29的根圆内延伸,并且其到芯轴15的径向间距大致上与球体19到芯轴15的间距相同。压力弹簧35的端部作用到离合器从动盘17上。压力弹簧35经由弹簧架元件37被加载轴向力,其中,弹簧架元件37与调整螺母30联接。由图1可知,弹簧架元件37为此具有沿径向向内突伸的节段38,该节段为每个压力弹簧35而具有销式的突出部39。突出部39用于分别容纳压力弹簧35以及导引该压力弹簧。与调整螺母30对准地,弹簧架元件37还优选具有多个以均匀的角距彼此设置的支撑区域41,这些支撑区域平行于突出部39地延伸并且在离合器从动盘17的闭锁位置中贴靠在离合器从动盘17上。
除第一凹部33外,传动机构壳体24还具有第二凹部43。由图4清楚可知,第二凹部43同样以均匀的角距形成在传动机构壳体24中,特别是成形为槽状。第二凹部43用于局部形状配合地容纳过梁式的触发节段44。
触发节段44是轴承架45的组成部分,所述轴承架45用于轴向推移轴向轴承47。轴向轴承47在此布置在芯轴15的朝向工具张紧装置11的端部上并对其导引。触发节段44的背向轴向轴承47的端部贴靠在用作调整元件的曲线环48上,所述曲线环48同样与调整环32尤其形状配合地联接。在此,曲线环48用于轴向推移触发节段44或轴承架45,从而轴向轴承47作为浮动轴承用于冲击钻操作,并且作为固定轴承用于钻机10的旋拧或钻孔操作。
如图5所示,在钻孔操作中,轴承架45用其触发节段44沿轴向经由曲线环48支撑在传动机构壳体24上,其中,离合器从动盘17为此具有凹部49,从容使成形在曲线环48上的间隔元件50与传动机构壳体24配合作用。为提高可传递的扭矩,这样来转动调整环32,以致于调整螺母30沿轴向在离合器从动盘17的方向上运动。在此,压力弹簧35经由弹簧架元件37以提高了的轴向压力压住离合器从动盘17。
在钻机10的钻孔状态下,支撑区域41和/或突出部39又将离合器从动盘17几乎压到挡块上,从而锁定扭矩离合器18。
