Description
本发明专利申请是CN93107886.5发明申请的分案申请。
本发明涉及一种紧固用螺旋装置,该装置为以螺旋方式将如手提式砂轮机上的砂轮或手锯上的圆锯那样的旋转工具紧固于传动轴上的安装用螺杆部(如外螺纹)的紧固用螺旋装置(例如,螺母),使用该螺旋装置,以很小的旋转力即可实行有力的紧固或松释,此外,对于过分紧固也能进行限制。
如将上例所示的砂轮或圆锯等旋转工具装配于传动轴上,以前的作法是:在传动轴端部形成凸缘及外螺纹,旋转工具嵌插于该外螺纹部分,在其外端旋上形成内螺纹的紧固用螺旋件,例如,螺母,由于该螺母的紧固,使旋转工具固定于该螺母与上述的凸缘之间。然而,在进行上述的螺母的紧固及放松操作时,通常需用如扳手等增力工具,其问题是,紧固或放松螺母的力的增加放大仅依该增力工具而定,所以不能得到充分的增加。
另外,其问题还在于,在使用上述旋转工具时,如果使用该旋转工具时产生冲击,则由于该冲击力及其反作用力的影响,上述的螺母的紧固力须格外地大,换替旋转工具时由于螺母过份紧固,即使使用如扳手那样的增力工具也无法卸下,更有甚者,不毁坏旋转工具即无法卸下螺母。
本发明的特征在于,紧固用螺旋装置包括:在法兰环上可转动地支承有旋转环,在上述旋转环上,可转动地支承有与安装用螺杆的外螺纹相同螺距的内螺纹、且该内螺纹的直径加工成大于上述外螺纹直径的螺旋构件,该螺旋构件偏心设置,以使该螺旋构件的一部分内螺纹与上述外螺纹螺旋配合。紧固时,凸缘固定,旋转环使螺旋构件发生公转,使得由此在该紧固件中生成的减速了的自转成为扭矩增大的紧固力。
本发明的第一个目的是:提供一种紧固用螺旋装置,所述的螺旋装置以很小的旋转力即可得到大的紧固力或旋松力,可以牢固地安装被固定件,另外,该装置由于增强扭矩提高了旋转力,可不用增力工具,直接手动操作紧固或放松。
本发明的第二个目的是:提供一种紧固用螺旋装置,该螺旋装置的法兰环与被紧固件靠接、转动即被固定,此时旋转环或操作环的转动即成为螺旋构件的转动,因此可以快速装卸紧固用螺旋而不必费时。
本发明的第三个目的是:提供一种紧固用螺旋装置,该螺旋装置因在旋转环与被紧固件之间夹装有可保持相对转动的法兰环,旋转环不会与被紧固件共转,因此可防止在被紧固件工作旋转时紧固用螺旋装置被过份地紧固。
本发明的第四个目的是:提供一种紧固用螺旋装置,该螺旋装置因在以被安装螺杆为轴心的圆周上均匀配置有多个螺旋构件,可均匀分配各螺旋构件的可变载荷,使紧固用螺旋装置能圆滑转动操作,紧固时能有效增大扭矩。
附图的简单说明
图1为紧固用螺旋装置的剖视图。
图2为紧固用螺旋装置的分解剖视图。
图3所示为螺母环的偏心状态说明图。
实施例
以下,根据附图详述本发明的一个实施例。
附图表示了紧固用螺旋装置,在图1、图2中,该紧固用螺旋装置10由法兰环11、旋转环12、作为螺旋构件的第一个螺母环13、第二个螺母环14和操作环15构成。在上述法兰环11、旋转环12、操作环15的各中心部位,形成有通孔18、19、20,以便***安装用螺杆17,该螺杆17位于如手提式砂轮机那样的电动工具的转动轴16上。另外,在上述转轴16上形成有凸缘21,作为被紧固件的旋转工具22、例如手提式砂轮机的砂轮即插装于上述的安装用螺杆17上,被安装、紧固于凸缘21和紧固用螺旋装置10之间。
在上述法兰环11上,旋转环12通过轴承23保持在可转动状态,同时,在旋转环12上,上述螺母环13、14分别通过轴承24、25保持在可转动状态。上述的旋转环12被压入上述操作环15而被固定成一体,此外,在操作环15的外周刻有便于转动操作的滚花15a,26为密封间隙用的○形垫圈。
上述螺母环13、14上的内螺纹27、28,其螺距与上述安装用螺杆17的外螺纹29的螺距相同。内螺纹27、28的螺纹直径比外螺纹29的大,而且,其内螺纹27、28各有一部分与安装用螺杆17的外螺纹29成为偏心螺旋配合。各螺母环13、14保持于旋转环12上。此外,第一个螺母环13和第二个螺母环14的相对偏心位置如图3所示,为在安装用螺杆17(外螺纹29)的轴心29a的圆周上,隔180度均等配置。再有,图3分别显示了内螺纹27、28,外螺纹29的各自有效直径,27a表示内螺纹27的中心,28a表示了内螺纹28的中心,图上示出各中心27a、28a相对外螺纹29的中心29a相隔180度。
用这一结构的紧固用螺旋装置10将前述的旋转工具22安装、固定于转轴16的安装用螺杆17上时,用手直接转动操作紧固用螺旋装置10的操作环15,将两个螺母环13、14的内螺纹27、28以螺旋配合旋着于该安装用螺杆17的外螺纹29上。在这旋紧过程中,当法兰环11未与旋转工具22接触时,操作环15、凸缘环11、旋转环12和两个螺母环13、14作为装配负载而作整体转动,由两个螺母环13、14的各内螺纹27、28的接触部分与安装用螺杆17的外螺纹29的螺纹配合旋进紧固用螺栓10。
接着,法兰环11与旋转工具22接触,使其转动增加了载荷,该载荷终止了法兰环11的转动。由此通过操作环15传给旋转环12的旋转力传至两个螺母环13、14,使这两个螺母环13、14产生公转,各螺母环13、14各自的内螺纹27、28沿安装用螺杆17的外螺纹29的周边作滚动。而且,由于内螺纹27、28的周长稍长于外螺纹29,因上述滚动运动而使各螺母环13、14产生自转。又因这一自转减小了旋转环12的沿螺纹螺距的送进速度,由此在各螺母环13、14上的扭距增大,扭矩增大的自转使各螺母环13、14以螺纹配合旋紧于安装用螺杆17上,将前述旋转工具22以提高了扭矩的紧固力紧固、固定于安装用螺杆17上。
再有,如上所述,两个螺母环13、14作均等对称配置时,因各螺母环13、14的扭矩增大,导致的单边负载均匀对称地作用于安装用螺杆17的周围,因此可进行圆滑平顺的紧固。
又,当直径相对较大的螺纹27、28的螺纹直径越是接近于安装用螺杆17的直径相对较小的外螺纹29的螺纹直径,则螺母环13、14的扭矩增高率越大,反之,则螺母环13、14的扭矩增高率就越小。换言之,当内螺纹27、28的周长越接近外螺纹29的周长,则扭矩增高率越大。
此外,在旋松紧固用螺栓10时,由于法兰环11已经接触到如旋转工具22等被紧固件,转动受阻,螺母环13、14处于可公转的状态,旋转环12的松释方向和转动操作使得螺母环13、14发生自转,由此,作用与前述同样的增高扭矩的力,该螺母环13、14即沿松释方向转动。
接着,螺母环13、14被松释,法兰环11离开旋转工具等被紧固件,产生这个转动后,整个紧固用螺旋装置10成为一体转动,旋转环12的转动即成如螺母环13、14的转动而能很快松释。
在上述实施例中显示了使用2个螺母环13、14的例子,但也有使用1个螺母环的结构,也有使用3个以上螺母环的结构。在用多个螺母环结构时,最好是这些螺母环与安装用螺杆的螺旋配合的位置对等地配置,以使载荷相对安装用螺杆均匀地分配。另外,本实施例中,虽然是以手动转动操作紧固用螺旋装置10,也可以使用扳手等增力工具。这样,可更轻松地进行紧固操作。
