Description

手持式工具及其夹紧装置 技术领域
本发明涉及一种手持式工具及其夹紧装置。
背景技术
多功能机是业界常见的手持式工具,它的工作原理是输出轴围绕自身的轴心线做摆动运动。因此,当用户在输出轴的自由端上安装有不同的工作头后,如直锯片、圆锯片、三角形磨砂盘、铲型刮刀后,可以实现多种不同的操作功能,如锯、切、磨、刮等,以适应不同的工作需求。
中国公开专利申请第CN101780668A号,公开的一种多功能机,包括电机,电机的电机轴连接有偏心销,在偏心销上套设有轴承,从而构成一个偏心轮结构。当电机轴旋转时,偏心轮结构可以围绕电机轴的轴心线做偏心旋转运动。多功能机的输出轴是垂直于电机轴设置的,在输出轴上固定的连接有一个拨叉组件,拨叉组件形成有相对的两个延伸臂,将偏心轮结构包围,两个延伸臂的内侧均与偏心轮结构中的轴承紧密接触,从而当偏心轮做偏心旋转时,偏心轮结构会带动拨叉产生水平方向上的摆动运动,又借助拨叉与输出轴的固定连接,使输出轴围绕其轴心线做摆动。在输出轴的自由端安装不同的工作头后,多功能机即可以在高速的摆动运动下实现多种操作功能。
但是,目前的多功能机仍然采用较为原始的工作头安装方式,即通过扳手将紧固螺栓拧松,而后将紧固元件从输出轴上取下;同样的,在附件的安装和更换上,也是采用同样的方式,需要借助扳手将紧固螺栓拧松才能够更换工作头并拧紧安装,操作起来十分繁琐且费时费力。
对比,业界技术人员也做了很多改进,通过快速夹紧装置来解决不需要借助扳手来安装和更换工作头。但是,还是存在了很多问题,如操作不够舒适;或是结构复杂,可靠性差等等。因此,实有必要提供一种改进的手持式工具,以解决上述问题。

具体实施方式
下面结合附图及具体实施方式对本发明作进一步的详细说明。
本实施方式中涉及的手持式工具具体是一种摆动型手持式工具,又称多功能机。但是本发明并不限于摆动手持式工具,也可以是转动型研磨手持式工具,如砂光机或角向磨光机等。
具体实施方式一
图1所示为本实施方式中多功能机30。该多功能机30具有壳体32、自 壳体32的内部延伸出的输出轴34、安装在输出轴34末端的工作头36、用于将工作头36固定在输出轴34末端的夹紧装置38。夹紧装置38包括夹紧单元40和操作组件42,其中夹紧单元40用于在轴向41上夹紧工作头36,操作组件42用于驱动夹紧单元40。轴向41大致沿平行于输出轴34的轴线X1延伸。
多功能机30工作时,输出轴34围绕其自身轴线X1做旋转摆动运动,从而沿摆动的两个方向产生较大的突变扭矩。因此,需要非常大的轴向夹持力来确保在所有的工作条件下将上述工作头36保持在输出轴34上,并不会出现打滑而影响工作效率或无法工作。本实施方式所提供的多功能机30能够满足上述需求,可以提供足够的夹持力,并能快速夹紧和释放工作头36,而无需使用另外的辅助工具。
壳体32内还设置有电机33、电机33具有电机轴35、将电机轴35输出的旋转运动转变为输出轴34的摆动运动的偏心传动机构37。该偏心传动机构37包括安装在电机轴上的偏心件39及套设在输出轴34上的拨叉41,偏心件39被包围在拨叉41的两个滑动表面之间。偏心件39转动时,通过与拨叉41的配合,将其转动运动转化成输出轴34相对于其自身轴线X1的摆动运动,且摆动角在约0.5至10度之间,并且摆动频率范围可设置为约每分钟5000至30000次。本实施例中,电机轴的轴线大致垂直于输出轴34的轴线X1。优选的,电机轴的轴线与输出轴34的轴线X1共面,构成中心平面。
再参见图1,将输出轴34的轴线X1所在直线定义为纵向,与轴线X1垂直的方向定义为横向,纸面的底部为下,纸面的顶部为上。后文的描述均采用此处的定义。输出轴34为中空状,纵向支撑在壳体32内的两个滚动轴承44、46之间。输出轴34上端收容在壳体32内并设有腔体48;下端设有延伸出壳体32用于安装工作头36的法兰盘50。法兰盘50上还开设有轴向的通孔52,该通孔52连通上述腔体48。
工作头36为一种直锯片,对本领域技术人员来说,很容易想到,工作头36也可以是其它附件,如圆锯片、砂盘、刮刀等。该工作头36横向设置,其具有用于安装在输出轴34上的平板状安装部54以及用于切割的切割部56。
夹紧单元40包括围绕平行于轴向41的轴线可枢转地锁紧件58、与锁紧件58配合的锁定件60。
锁定件60用于将工作头36固定在输出轴34的法兰盘50上。锁定件60穿过工作头36的安装部54和通孔52,进而伸至输出轴34的腔体48内。锁定件60包括位于底部的环状压板62和自压板62的中部轴向向上延伸的杆部64,杆部64的末端设有外螺纹(图中未示),且杆部64穿过通孔52后,不能相对输出轴34转动。安装时,锁定件60的杆部64穿过输出轴34的腔体48,并与锁紧件58螺纹锁紧,从而将工作头36固定在输出轴34的法兰盘50上,并夹持在法兰盘50的底面和压板62的顶面之间。
锁紧件58围绕平行于轴向41的轴线可枢转地设置在壳体32上,位于输出轴34的上端。当然,如本领域技术人员所理解的,锁紧件58也可以旋转地设置在输出轴32的腔体48内。锁紧件58大致呈圆环状,能够在壳体32内自由旋转,其中部轴向开设有螺纹孔66。沿一个方向旋转操作组件42,带动锁紧件58相对轴线X1旋转,从而使锁紧件58的螺纹孔66与锁定件60的杆部64螺纹锁紧。在锁紧状态下,沿相反方向旋转操作组件42,则可驱动锁紧件58相对轴线X1反向旋转,从而使锁紧件58的螺纹孔66与锁定件60的杆部64松开。
需要指出,本实施方式中,锁定件60设有杆部,锁紧件58上开设螺纹孔,本发明并不限于这种结构。对本领域技术人员来说,很容易想到,也可以将杆部设置在锁紧件上,而将螺纹孔设置在锁定件上,此时同样需要将锁定件设置成不可相对输出轴转动。另外,本发明所指的螺纹配合锁紧,可以是普通单头螺纹配合,也可以是双头或多头;螺纹牙的大小也不限,可以是粗牙或细牙;螺纹牙型形状可以是三角形螺纹、矩形螺纹、梯形螺纹、锯齿形螺纹中的一种。
输出轴34摆动运动时,会带动工作头36、夹紧单元40一起摆动。本实施方式中的操作组件42的部分元件需要设置在壳体外部,便于使用者直接手动操作,而无需使用其它的辅助工具。而如果夹紧单元40摆动时同时带动操作组件42摆动,则会影响到使用者的操作手感,甚至在一些状况下会有安全方面的问题,因此需要在夹紧单元40将工作头36锁紧后,避免带动操作组件42同步摆动。
本实施方式中,操作组件42具有配合模式和脱开模式,从而实现操作组件42可选择地与夹紧单元40无相对转动地连接。需要将锁紧件58与锁定件60相对锁紧或松开时,可选择地将操作组件42处于配合模式,操作组件42 与夹紧单元40无相对转动地连接,然后可以直接驱动锁紧件58。在锁紧件58锁紧后需要工作时,可选择将操作组件42处于脱开模式,操作组件42则可以与夹紧单元40之间相对转动,从而操作组件42不会受到夹紧单元40摆动的影响。
参见图2和图3,操作组件42包括操作件68和驱动件70。操作件68可操作的带动驱动件70在与夹紧单元40配合和脱开的两个位置之间活动。驱动件70与夹紧单元40配合,操作件68与夹紧单元40无相对转动地连接。此时,操作组件42处于配合模式;驱动件70脱开与夹紧单元40的配合,操作件68与夹紧单元40可相对转动。此时,操作组件42处于脱开模式。在这里,定义驱动件70朝着与夹紧单元40配合的方向为配合方向(可参见图3中箭头E),与之相反的方向定义为脱开方向。
夹紧装置38包括围绕平行于轴向41的轴线可转动设置在壳体32上的安装座72。操作件68可活动安装在安装座72上,从而实现操作件68可同安装座72一起围绕围绕平行于轴向41的轴线转动。优选的,安装座72围绕轴线X1转动。操作件68还包括供操作者使用的操作部69。
安装座72上设有导向槽74,操作件68上设有导向件76。在这里,导向槽74具有纵长延伸的导向面,导向件76可沿导向面转动和滑动。从而,操作件68可围绕移动的转动轴线翻转设置在安装座72上,实现驱动件70与夹紧单元40配合和脱开。在这里,操作件68翻转设置,围绕移动的转动轴线,没有固定的转动轴线。移动的转动轴线垂直于输出轴34的轴线X1,即垂直于轴向。优选的,移动的转动轴线垂直于中心平面。移动的转动轴线在垂直于移动的转动轴线的平面内线性移动。线性移动的轨迹包括直线、曲线、折线、弧线或直线、曲线、折线和弧线其中至少两个的组合。而在本实施例中,线性移动的轨迹为折线。因此,操作件68即有转动又有线性移动,相对于安装座72复合运动。如此,即可以满足操作的舒适性,同时也可以节省零部件,使结构更加简单,可靠。复合运动也可以具有固定的运动轨迹,更加方便操作。
当然,如本领域技术人员所理解的,导向槽74和导向件76的位置也可以互换,如导向槽74设置在操作件68上;导向件76设置在安装座72上。如此,也可以实现本发明的创作构思。
驱动件70固定设置在操作件68上。当然,驱动件70也可与操作件68 一体成型。操作件68上设有凹槽78,驱动件70固定设置在凹槽78的内壁上。在这里,驱动件70包括设置在凹槽78内壁的凸台80。锁紧件58上设有与驱动件70配合的配合部82。图3所示,凸台80与锁紧件58上的配合部82在轴向41上错开,两者脱开配合,此时,操作组件42处于脱开模式,操作件68无法带动夹紧单元40转动;而当操作件68翻转后,使凸台80与锁紧件58上的配合部82配合,操作组件42处于配合模式,则驱动操作件68就可以带动锁紧件58围绕轴线X1转动。
参见图3和图4,凸台80包括与操作件68相连的两侧面84以及连接两侧面的连接面86,其中两侧面84可选择地与锁紧件58配合。配合部82包括与驱动件70可选择配合的两配合面88。其中,两配合面88相互平行设置,而两侧面84相互倾斜设置。当然,两配合面88也可以相互倾斜、两侧面84平行;或两配合面88、两侧面84均相互倾斜或相互平行设置。
在本实施方式中,驱动件70包括两对称设置在操作件68上的凸台80、锁紧件58上设有两对称设置的配合部82。当然,如本领域技术人员所理解的,凸台80和配合部82的个数可以是若干个,都可以实现本发明的创作构思。当然,驱动件70和配合部82的具体形式不局限于本实施方式,还可以是通过齿部与齿部的配合、凹槽与凸起的配合等,只要能使驱动件70与锁紧件58配合时可带动锁紧件58转动即可。
如图4所示,如若当操作件68翻转后,凸台80位于配合部82旁边,其任一侧面84均未与任一配合面88抵靠,此时,只需将操作件68旋转一定的角度,如图5所示,使凸台80的一侧面84与配合部82的一配合面88抵靠,使驱动件70与锁紧件58配合,从而驱动操作件68可带动锁紧件58围绕轴线X1转动。
再参见图2和图3,安装座72位于壳体32的上部,并可围绕轴线X1可转动设置地壳体32上。安装座72包括圆柱状的连接部90、与连接部90连接的安装盘92及连接在安装盘92上的支架94。
安装盘92包括相对设置的上表面96和下表面98。安装盘92的上表面96上开设有轴向延伸的内孔100,该内孔100穿透连接部90,用于供锁紧件58穿过。安装时,锁紧件58穿过内孔100,并使配合部82至少部分位于安装盘92的上表面96的上方。
夹紧装置38还包括固定座102,固定座102通过螺钉104固定连接在壳 体32上。在这里,连接部90自下表面98轴向延伸,连接部90的外径基本等于固定座102上的连接孔106的内径,从而连接部90可以插入到固定座102内,使得安装座72可以相对于固定座102转动。而安装座72通过轴用挡圈108卡设有在固定座102内,阻止了其轴向移动。
在本实施方式中,两个导向槽74对称设置在支架94上。支架94包括两个独立设置在安装盘92上的侧板110,两个导向槽74分别设置在两个侧板110上。当然,两侧板110也可以连接在一起。
导向槽74包括相互连通的第一、第二槽112和114,而第一、第二槽112和114之间的夹角最好为钝角。第一槽、第二槽112和114至少其中之一相对于轴向倾斜设置。在本实施方式中,第一槽、第二槽112和114均相对于轴向41倾斜设置。
当然,导向槽74的具体形状并不仅限于本实施方式,如导向槽可以是一直线槽,该直线槽可以平行于轴向41设置;或相对于轴向41倾斜设置。
进一步,侧板110上还设有配合槽116和止挡槽118,操作件上68还设有止挡销120,当操作件68位于不同的位置时,止挡销120可选择与位于配合槽116或止挡槽118中。
在这里,止挡销120和止挡槽118组成了止挡机构,其作用在下面会详细阐述。当然,止挡机构也并仅局限于将止挡槽设置在侧板上,止挡销设置在操作件上。也可以将止挡槽设置在操作件上,止挡销设置在侧板上,在第二实施方式会详细阐述。
导向件76为圆柱销76,两个圆柱销76对称设置在操作件68上,且分别收容于导向槽74中。当然,两个圆柱销也可以连接成一个圆柱销,其两端分别在导向槽内转动和滑动。通过导向槽74和可在导向槽74中转动和滑动的圆柱销76,使得操作件68可相对于壳体32围绕移动的转动轴线转动。而圆柱销76在导向槽74中的运动轨迹可以是沿轴向41由上而下,或沿轴向41先向上运动,再由上向下运动。
在本实施方式中,导向件76与操作件68上的孔过盈配合。当然,如本领域技术人员所熟悉的,导向件76与操作件68的连接方式还有很多,如焊接、螺纹连接等。
如上所述,通过设置对称的导向件和导向槽,便于操作者操作操作件68。当然,如果仅在一侧设置相配合的导向件和导向槽也可以实现操作件68可相 对于壳体32复合运动。
而为了操作更顺畅,在操作件68上设有与安装座72配合的凸轮面122。凸轮面122包括两个不同直径的挤压面。通过凸轮面122与安装座的上表面96抵接,同时,圆柱销76在导向槽74内转动和滑动,操作件68可以顺畅地相对于壳体32翻转,从而,操作件68可带动凸台80在与锁紧件58配合和脱开与锁紧件58配合之间活动。
当然,凸轮面122的具体形状也不仅限于具有两个不同直径的挤压面,其还可以设置为其他圆滑曲面。
一并参考图1、图3和图6、图8,操作组件42由初始位置移动至张开位置。如图1和图3所示,在初始位置时,操作件68贴合在壳体32的顶部,此时,可通过卡合结构(未标号)将操作件68卡设在壳体32上。而此时,为了便于操作件68卡设在壳体32中,侧板110上开设的配合槽116用于容纳止挡销120。锁紧件58收容在安装座72上的内孔100内,并可轴向移动地支撑在输出轴34的顶端。在这里,锁紧件58收容在安装座72内,可以相对安装座72旋转,也可以或连同安装座72一起相对于固定座102旋转。进一步地,锁紧件58的底端与安装座72的内壁之间设有弹性件124,以提供锁紧件58朝着与锁定件60配合的弹簧力。进一步参考图3,当操作件68处于初始位置时,凸台80与锁紧件58上的配合部82在轴向41上错开,两者脱开配合,即处于非配合模式。此时,凸台80与安装座72的上表面96的距离相对较远。
这里,施力于操作部69,操作组件42通过凸轮面122与安装座72的上表面96抵接,即操作件68带动驱动件70沿配合方向E活动;同时,圆柱销76在导向槽74内转动和滑动,从而,操作件68翻转至张开位置,如图6和图8所示。这时,止挡销120与止挡槽118配合(未图示),可阻止操作件68进一步沿配合方向E活动,即阻止驱动件70脱开与锁紧件58配合。当然,也就阻止了操作部69朝着靠近工作头36的方向进一步活动。如此,避免驱动件70脱开与锁紧件58的配合,确保了工作头顺利完成拆装。
此时,凸台80相对于初始位置在轴向41向下移动,即凸台80与锁紧件58上的配合部82在轴向41上至少部分重叠,凸台80与安装座72的上表面96的距离相对较近。进一步参见图5,驱动件70可与锁紧件58上的配合部82配合,从而可带动锁紧件58一起转动,使锁紧件58和锁定件60螺纹锁 紧。显然,当锁紧件58和锁定件60锁紧后,再将操作组件42从张开位置扳回至初始位置,凸台80相对于张开位置在轴向41向上移动,使凸台80与锁紧件58上的配合部82脱离配合。可见,驱动件70在操作件68的翻转过程中,在轴向上有位移,同时,为了更好与锁紧件58配合,在径向上也可以有位移。
再参见图2和图3,在安装座72和操作件68之间设有弹性元件126,弹性元件126提供促使操作件68位于张开位置的弹簧力。如此,便于操作者将操作件68翻转至张开位置。具体的,操作件68上设有定位销128,安装座72上设有定位块130,弹性元件126套设在定位销128上,且一端卡设在定位块130上,另一端卡设在操作件68的卡槽132内。当然,也可以将设置两个弹性元件126,且分别安装在两个侧板110的外侧,或是在任一侧板110的外侧设置弹性元件126,都可以提供促使操作件68位于张开位置的弹簧力,便于操作者沿配合方向E移动操作件68。
请参考图1、图6、图8至图9,结合多功能机30的四个位置示意图,具体描述多功能机30安装工作头36的具体操作方法。图1中,多功能机30处于第一位置,此时操作件68处于初始位置,锁定件60插入输出轴34内,但是还未插入锁紧件58中。图6中,多功能机30处于第二位置,此时操作件68翻转至张开位置,驱动件70可与锁紧件58配合;此时锁定件60刚插入锁紧件58内,但是锁紧件58未开始拧紧。图8中,多功能机30处于第三位置,此时操作件68旋转若干圈后,锁紧件58和锁定件60轴向锁紧。图9中,多功能机30处于第四位置,此时操作件68回复至初始位置,驱动件70与锁紧件58脱开配合。下面详细介绍具体操作过程。
图1所示,首先将工作头36安装在输出轴34的法兰盘50与锁定件60之间,并将锁定件60插入至输出轴34的内腔44中。如若工作头36的安装部54上的开口为封闭的,需要将锁紧件58与锁定件60完全脱离开,以将其从输出轴34上取下,再将锁定件60穿过工作头36的开口后安装至输出轴34内。如若工作头的开口加工成非封闭的,留有可穿过锁定件的杆部的缺口。此种情况无需将锁定件完全从锁紧件上拆下,只需拧松锁紧件,使锁定件与输出轴的承接部之间留出可供工作头的安装部穿过的间隙即可。
如图6所示,将锁定件60插入锁紧件58的螺纹孔66中,使其杆部64的顶端外螺纹与锁紧件58的螺纹孔66接触,并推动锁紧件58轴向移动一定 距离,直到锁定件60的压板62抵靠到工作头36的安装部54的下表面,且工作头36的安装部54的上表面抵靠在输出轴34的法兰盘52的下表面。
沿配合方向移动操作部69,使操作件68由初始位置操作至张开位置。再参见图7,凸台80正好位于配合部82旁边,旋转操作件68则可以使凸台80与配合部82配合(可参见图5),进而操作件68就可以带动锁紧件58相对锁定件60转动。由于锁紧件58的螺纹孔66与锁定件60的杆部是螺纹配合,在螺纹旋紧力的作用下,锁紧件58在转动的同时轴向下移。
而如果操作件68翻转过程中,还未运动至完全的张开位置,凸台80正好位于配合部82上方并被配合部82止挡,阻止了操作件68的进一步运动,这时,只需旋转操作件68,使凸台80让开配合部82,使其位于配合部82的旁边,再重复上述步骤。
如图8所示,继续旋转操作件68,通过驱动件70带动锁紧件58进一步下移,并消除工作头36与锁定件60和输出轴34的法兰盘52之间的轴向间隙,直到感觉到操作件68旋转困难,此时工作头36、锁定件58以及法兰盘52三者彼此之间分别具有非常大的轴向正压力,相应具有非常大的摩擦力,从而可传递足够的扭矩以防止工作头36与锁定件60以及输出轴34的法兰盘52之间出现相对滑动,而影响工作效率。
操作件68处于张开位置,驱动件70与锁紧件58配合,凸台80的纵长延伸方向与轴向41平行。也就是说,凸台80的两侧面84的延伸方向与轴向41平行,从而在围绕轴线X1转动过程中,凸台80也可以很好与锁紧件58上的配合部82配合。
如图9所示,待锁紧件58与锁定件60完全锁紧后,沿脱开方向移动操作部69,使操作件68回复至初始位置。此时,驱动件70脱开与锁紧件58的配合,进而防止锁紧件58带动操作组件42一起摆动。
通过上文对安装工作头36的操作步骤的介绍,很容易理解,拆卸工作头36时执行相反的操作即可。需要拆卸工作头36时,只需将操作组件42转动至张开位置,并使驱动件70与锁紧件58配合;然后逆时针旋转操作组件42,通过驱动件70带动锁紧件58与锁定件60相对转动而松开螺纹连接,使锁定件60轴向下移一定距离;最后,操作组件42继续旋转,直到锁紧件58与锁定件60完全脱开螺纹连接,此时可将锁定件60从输出轴34中拆下,取出工作头36。
具体实施方式二
如图10图所示,本发明的第二实施方式,提供一种多功能机200,与第一实施方式中的多功能机30相同,包括壳体32、自壳体32的内部延伸出的输出轴34、安装在输出轴34末端的工作头36、用于将工作头36固定在输出轴34末端的夹紧装置238。夹紧装置238包括夹紧单元40和操作组件242,其中夹紧单元40和操作组件242的具体结构、原理基本同第一实施方式,下面主要针对与第一实施方式的区别的结构进行描述。
请参见图11,本实施方式与第一实施方式的不同之处有,设置在安装座272和操作件268之间的弹性元件226的安装位置。在本实施方式中,在每个侧板210的外侧均设有盖板221。每个盖板221上设有第一定位柱222和第二定位柱223。每个侧板210上设有第一定位孔212和第二定位孔213。其中,第一定位柱222与第一定位孔212配合,第二定位柱223与第二定位孔213配合,从而将盖板221安装在侧板上。当然,还可以在侧板210上设有与盖板221的侧壁相卡设的弹性块214,更好的固定盖板221。
侧板210上还设有定位销215(对称设置,图中显示了一个),盖板221上设有收容定位销215的收容槽225(对称设置,图中显示了一个)。弹性元件226套设在定位销215上,且一端通过侧板210上的孔卡设在侧板210上;另一端卡设在导向件276上。如此,弹性元件226提供促使操作件268位于张开位置的弹簧力,便于操作者将操作件268翻转至张开位置。
如上所述,两个弹性元件226对称设置,便于施力均衡,当然,如果仅在安装座272的一侧设有一弹性元件226也可。
同第一实施方式,本实施方式中安装座272上设有导向槽74,操作件268上设有导向件276,导向件276可沿导向槽74转动和滑动。从而操作件268可翻转设置地设置在安装座272上,实现驱动件70与夹紧单元40配合和脱开。请参见图11,本实施方式与第一实施方式的不同之处有,导向件276与操作件268的安装方式。在本实施方式中,操作件268上设有螺纹孔,导向件276穿过导向槽74与螺纹孔配合。
同第一实施方式,本实施方式中的夹紧装置238也包括设置在安装座272和操作件268之间的止挡机构,当驱动件70与夹紧单元40配合时,止挡机构用于限制操作件268沿配合方向进一步活动,也就是限制驱动件70脱开与夹紧单元40的配合。而不同之处还在于:请继续参见图11,本实施方式中, 止挡机构包括设置在操作件268上的止挡槽218、设置在安装座272上的止挡销220。
具体的,止挡销220固定安装在安装座272上的侧板210上。止挡销220可以是圆柱销,与侧板210上的孔216过盈配合。当然,如本领域技术人员所熟悉的,止挡销220的截面形状不限,且与侧板210的连接方式也有很多种,如焊接、螺纹连接等。
在本实施方式中,止挡槽218是一端开口、另一端封闭的槽,且并非通槽。也就是说该止挡槽218并没有贯通凹槽78的内壁。止挡槽218包括容纳止挡销220的容纳部230,在操作件268相对安装座272的翻转过程中,止挡销220可在容纳部230内自由活动。
参见图10,沿配合方向移动操作部269,使操作件268由初始位置操作至张开位置。再参见图12,凸台80正好位于配合部82旁边,旋转操作部269则可以使凸台80与配合部82配合,进而操作件268就可以带动锁紧件58相对锁定件60转动。由于锁紧件58的螺纹孔66与锁定件60的杆部是螺纹配合,在螺纹旋紧力的作用下,实现安装或拆卸工作头36。
而在此时,可参见图13,止挡槽218包括与容纳部230连通的临界止挡部232,当驱动件70与夹紧单元40配合时,止挡销220被临界止挡部232止挡,用于阻止操作件268进一步沿配合方向E活动,即阻止驱动件70脱开与锁紧件58配合。当然,也就阻止了操作部269朝着靠近工作头36的方向进一步活动。如此,避免驱动件70脱开与锁紧件58的配合,确保了工作头顺利完成拆装。
而如若操作件268在沿配合方向E运动过程中,还未运动至完全的张开位置,则发现驱动件70受阻未能与锁紧件58上的配合部82配合。具体可参见图14和图15,凸台80正好位于配合部82上方并被配合部82止挡,阻止了操作件268的进一步沿配合方向E运动。遇到这样情况,在第一实施方式中,需要旋转操作件68,使凸台80让开配合部82,使其位于配合部82的旁边,但是在操作过程中,操作者经常不会注意,而会继续以配合部82止挡凸台80的部分为支点,继续沿配合方向E运动,造成误操作。
因此,在本实施方式中,请参见图16,止挡槽218还包括设置在止挡槽218的槽底的中间止挡部234,操作件268在沿配合方向E运动过程中,当驱动件70受阻未能与锁紧件58配合时,止挡销220被中间止挡部234止挡, 用于阻止操作件268进一步沿配合方向E活动。当然,也就阻止了操作部269朝着靠近工作头36的方向进一步活动。如此,操作者也就会及时发现,此时需要旋转操作件268,使凸台80让开配合部82,使其位于配合部82的旁边,再继续旋转操作件268,则可以使凸台80与配合部82配合,进而操作件268就可以带动锁紧件58相对锁定件60转动,从而实现安装或拆卸工作头36。
在本实施方式中,中间止挡部234和临界止挡部232相邻设置。
通过上文描述,本发明的多功能机30和200通过采用安装在壳体32上的夹紧装置38和238,在不采用其它辅助工具的情况下,快速驱动锁紧件58与锁定件60锁紧或脱开,实现工作头36的快速安装或拆卸。
另外,夹紧装置38进一步地设置止挡机构,避免了当驱动件与夹紧单元配合,操作件驱动夹紧单元时,操作件进一步沿配合方向活动,使得驱动件与夹紧单元脱开配合,从而无法进行正常工作。同时,止挡机构也可以及时提醒驱动件在朝着与锁紧件配合过程中,被配合部阻止,进而无法带动锁紧件运动,防止误操作。
具体实施方式三
图17至图20为本发明的第三实施方式。请参见图17和图18,第三实施方式提供一种多功能机300,基本与第一实施方式中的多功能机30相同,包括壳体32、自壳体32的内部延伸出的输出轴34、安装在输出轴34末端的工作头36、用于将工作头36固定在输出轴34末端的夹紧装置338。
在本实施方式中,参见图17和图18,夹紧装置338包括夹紧单元340和操作组件342,其中夹紧单元340和操作组件342的基本原理同第一实施方式,但在具体结构上与第一实施方式有区别。
操作组件342包括操作件368和驱动件370。操作件368可操作的带动驱动件370在与夹紧单元340配合和脱开的两个位置之间活动。驱动件370与夹紧单元340配合,操作件368与夹紧单元340无相对转动地连接。此时,操作组件342处于配合模式,操作件368旋转可带动夹紧单元340锁紧或释放工作头36;驱动件370脱开与夹紧单元340的配合,操作件368与夹紧单元340可相对转动。此时,操作组件342处于脱开模式。在这里,定义驱动件370朝着与夹紧单元340配合的方向为配合方向(可参见图17中箭头E),与之相反的方向定义为脱开方向。
操作件368上设有圆孔,在本实施方式中,驱动件370为圆销。驱动件 370与圆孔过盈配合,从而将驱动件370相对固定的安装在操作件368上,使操作件368可带动驱动件370一起活动。
夹紧装置338包括围绕平行于轴向41的轴线可转动设置在壳体32上的安装座372。操作件368可活动安装在安装座372上,从而实现操作件368可同安装座372一起围绕轴线X1转动。
安装座372上设有导向槽374,操作件368上设有导向件,在这里,导向件和驱动件370固定连接。进一步的,导向件和驱动件370可以一体成型设置。安装时,导向件(驱动件370)穿过导向槽374后与操作件368上的圆孔配合。
在本实施方式中,导向槽374为直线槽,具有纵长延伸的导向面,导向件370沿导向面转动和滑动。从而使操作件368可围绕移动的转动轴线翻转设置地设置在安装座372上,实现驱动件370与夹紧单元340配合和脱开。在这里,操作件368翻转设置,围绕移动的转动轴线,没有固定的转动轴线。移动的转动轴线垂直于输出轴34的轴线X1,即垂直于轴向。优选的,移动的转动轴线垂直于中心平面。移动的转动轴线在垂直于移动的转动轴线的平面内线性移动。在本实施例中,线性移动的轨迹为直线。因此,操作件368即有转动又有线性移动,相对于安装座372复合运动。如此,即可以满足操作的舒适性,同时也可以节省零部件,使结构更加简单,可靠。
为了操作更顺畅,在操作件368上设有与安装座372配合的凸轮面322。通过凸轮面322与安装座372的上表面抵接,同时,导向件370在导向槽374内转动和滑动,操作件368可以顺畅地相对于壳体32翻转,实现操作组件342在配合模式和脱开模式之间转换。
在安装座372和操作件368之间设有弹性元件326,弹性元件326提供促使操作件368位于张开位置的弹簧力。如此,便于操作者将操作件368翻转至张开位置。具体的,安装座372上设有定位销328,弹性元件126套设在定位销328上,且一端穿过安装座372上的孔卡设在操作件368上,另一端卡设在安装座372上。
夹紧单元340包括围绕平行于轴向41的轴线可枢转地锁紧件358、与锁紧件358螺纹配合的锁定件360。锁紧件358上设置有与驱动件370配合的配合部382。与第一实施方式所不同的是,在本实施方式中,配合部382为设置在锁紧件358周向上的四个配合凹槽。当然,配合凹槽的个数可以N个, 并不局限于本实施方式中的四个,只需可供驱动件370插入即可。
具体操作,请参考图17,操作组件342位于初始位置。操作件368贴合在壳体32的顶部,此时,可通过卡合结构(未标号)将操作件368卡设在壳体32上。操作件368处于初始位置时,锁紧件358上的配合部382虽然突伸出安装座372的上表面,但与驱动件370在轴向41上错开,两者脱开配合,操作组件342处于脱开模式。
施力于操作件368,操作组件342通过凸轮面322与安装座372的上表面96抵接,即操作件368带动驱动件370沿配合方向E活动;同时,导向件370在导向槽374内转动和滑动,从而,操作件368翻转至张开位置,如图19和图20所示。此时,驱动件370相对于初始位置在轴向41向下移动,使驱动件370与锁紧件358上的配合部382在轴向41上至少部分重叠。从而驱动件370插入在配合部282中,可带动锁紧件358一起转动,使锁紧件358和锁定件360螺纹锁紧或松开。从而实现安装或更换工作头36。显然,当安装或更换工作头36完成后,再将操作组件342从张开位置扳回至初始位置,驱动件370相对于张开位置在轴向41向上移动,使驱动件370与配合部382脱离配合。
具体实施方式四
图21至图23为本发明的第四实施方式。具体请参见图21,第四实施方式提供一种多功能机400,基本与第一实施方式中的多功能机30相同,包括壳体32、自壳体32的内部延伸出的输出轴34、安装在输出轴34末端的工作头(未图示)、用于将工作头固定在输出轴34末端的夹紧装置438。
在本实施方式中,夹紧装置438包括夹紧单元440和操作组件442,其中夹紧单元440和操作组件442的基本原理同第一实施方式,但在具体结构上与第一实施方式有区别。
操作组件442包括操作件468和驱动件470。操作件468可操作的带动驱动件470在与夹紧单元440配合和脱开的两个位置之间活动。驱动件470与夹紧单元440配合,操作件468与夹紧单元440无相对转动地连接。此时,操作组件442处于配合模式,操作件468旋转可带动夹紧单元440锁紧或释放工作头;驱动件470脱开与夹紧单元440的配合,操作件468与夹紧单元440可相对转动,此时,操作组件442处于脱开模式。
在本实施方式中,驱动件470固定设置在操作件468上。操作件468上 设有凹槽478,驱动件470设置在凹槽478的内壁上。在这里,驱动件470包括设置在凹槽478内壁上的第一、第二驱动面471和473。第一、第二驱动面471和473平行于操作件468的延伸方向。
如图21所示,第一、第二驱动面471和473与夹紧单元440在轴向41上错开,两者脱开配合,此时,操作组件442处于脱开模式,操作件468无法带动夹紧单元440转动;而当操作件468翻转后,如图22所示,第一、第二驱动面471和473与夹紧单元440配合,操作组件442处于配合模式。
请参见图23,夹紧装置438包括围绕平行于轴向41的轴线可转动设置在壳体32上的安装座472。操作件468可活动安装在安装座472上,从而实现操作件468可同安装座472一起围绕轴线X1转动。
安装座472上设有导向槽474,操作件468上设有导向件476。在本实施方式中,导向槽474包括分开设置的第一、第二导槽412和414。第一、第二导槽412和414相互不连通。第一、第二导槽412和414至少其中之一可以是弧形槽。而在本实施例中,第一导槽412为腰形槽;第二导槽414为弧形槽。优选的,第二导槽414为半圆形槽。
导向件476包括收容在第一导槽412中的第一导件477、收容在第二导槽414中的第二导件479。安装时,第一导件477穿过第一导槽412连接到操作件468上;第二导件479穿过第二导槽414连接到操作件468上。第一、第二导槽412和414均具有纵长延伸的导向面,如此,第一导件477可在第一导槽412中转动和滑动;第二导件479可在第二导槽414中转动和滑动,从而使操作件468可围绕移动的转动轴线翻转设置在安装座472上,实现驱动件470与夹紧单元440配合和脱开。移动的转动轴线垂直于输出轴34的轴线X1,即垂直于轴向。优选的,移动的转动轴线垂直于中心平面。移动的转动轴线在垂直于移动的转动轴线的平面内线性移动。在本实施例中,线性移动的轨迹为曲线。因此,操作件468即有转动又有线性移动,相对于安装座472复合运动。如此,即可以满足操作的舒适性,同时也可以节省零部件,使结构更加简单,可靠。
为了操作更顺畅,在操作件468上设有与安装座472配合的凸轮面422。通过凸轮面422与安装座472的上表面抵接,同时,第一导件477在第一导槽412内转动和滑动,第二导件479在第二导槽414内转动和滑动,操作件468可以顺畅地相对于壳体32翻转,实现操作组件442在配合模式和脱开模 式之间转换。
在安装座472和操作件468之间设有弹性元件426,弹性元件426提供促使操作件468位于张开位置的弹簧力。如此,便于操作者将操作件468翻转至张开位置。在本实施方式中,弹性元件426套设第一导件477上,且一端卡设在安装座472上,另一端卡设在第一导件477上。
夹紧单元440包括围绕平行于轴向41的轴线可枢转地锁紧件458、与锁紧件458螺纹配合的锁定件460。锁紧件458上设置有与驱动件470配合的配合部482。与第一实施方式所不同的是,配合部482包括设置在锁紧件458周向上的若干对称设置的配合面。优选的,与驱动件470配合的配合面的个数为偶数,且相正对的两配合面之间的距离等于第一、第二驱动面471和473之间的距离。且这些若干配合面在垂直于轴向41的平面内的投影形成边数为偶数的正多边形。优选的,配合面的个数为6个或8个等。如此,第一、第二驱动面471和473可卡设两相正对的配合面,带动锁紧件458一起围绕轴线X1转动。在本实施方式中,配合面的个数为6个。也就是说,锁紧件458为加长的六角螺母,与锁定件460(螺栓)螺纹连接。
具体操作,请参考图21,操作组件442位于初始位置。操作件468贴合在壳体32的顶部,此时,可通过卡合结构(未标号)将操作件468卡设在壳体32上。操作件468处于初始位置时,锁紧件358上的配合部482虽然突伸出安装座472的上表面,但与驱动件470在轴向41上错开,两者脱开配合,操作组件442处于脱开模式。
施力于操作件468,操作组件442通过凸轮面422与安装座472的上表面96抵接,即操作件468带动驱动件470活动;同时,第一导件477在第一导槽412内转动和滑动,第二导件479在第二导槽414内转动和滑动,从而,操作件468翻转至张开位置,如图22所示。此时,驱动件470相对于初始位置在轴向41向下移动,使驱动件470与锁紧件358上的配合部482在轴向41上至少部分重叠。从而第一、第二驱动面471和473卡设配合部482的两相正对的配合面,可带动锁紧件458一起转动,使锁紧件458和锁定件460螺纹锁紧或松开。从而实现安装或更换工作头。显然,当安装或更换工作头完成后,再将操作组件442从张开位置扳回至初始位置,驱动件470相对于张开位置在轴向41向上移动,使驱动件470与配合部482脱离配合。
在本实施例中,第一、第二驱动面471和473可以对称设置。但优选的, 是不完全对称设置,其中至少一个驱动面的延伸长度大于另一个的延伸长度。如此设置,在操作件468翻转的过程中,延伸长度较长(实施方式中的第一驱动面471)首先与配合部482的一个配合面相接触,随着操作件468的翻转,可以调整锁紧件458的位置,方便延伸长度较短(实施方式中的第二驱动面473)更好的与正对的配合面相接触,而无需旋转操作件468,非常方便。
具体实施方式五
图24至图27为本发明的第五实施方式。具体可参见图24,第五实施方式提供一种多功能机500,基本与第四实施方式中的多功能机30相同,包括壳体32、自壳体32的内部延伸出的输出轴34、安装在输出轴34末端的工作头(未图示)、用于将工作头固定在输出轴34末端的夹紧装置538。请结合图24和图26,夹紧装置538包括夹紧单元540和操作组件542。其中夹紧单元540的结构基本同第四实施方式,但操作组件542的安装方式和操作方法与上述实施方式有区别。
操作组件542包括操作件568和驱动件570(参见图27)。操作件568可操作的带动驱动件570在与夹紧单元540配合和脱开的两个位置之间活动。驱动件570与夹紧单元540配合,操作件568与夹紧单元540无相对转动地连接。此时,操作组件542处于配合模式,操作件568旋转可带动夹紧单元540锁紧或释放工作头;驱动件570脱开与夹紧单元540的配合,操作件568与夹紧单元540可相对转动。此时,操作组件542处于脱开模式。
夹紧装置538包括围绕平行于轴向41的轴线可转动设置在壳体32上的安装座572。操作件568可活动安装在安装座572上,从而实现操作件568可同安装座572一起围绕轴线X1转动。
安装座572上设有导向槽574,操作件568上设有导向件576。在本实施方式中,导向槽574包括分开设置的第一、第二导槽512和514。第一、第二导槽512和514相互不连通,第一、第二导槽512和514至少其中之一可以是弧形槽。而在本实施例中,第一导槽512为弧形槽;第二导槽514为直槽。优选的,第二导槽514的延伸方向大致与轴线X1垂直。更优选的,第一、第二导槽512和514的两个延伸方向之间的夹角为锐角。
导向件576包括收容在第一导槽512中的第一导件577、收容在第二导槽514中的第二导件579。安装时,第一导件577穿过第一导槽512连接到操作件568上;第二导件579穿过第二导槽514连接到操作件568上。第一、 第二导槽512和514均具有纵长延伸的导向面,如此,第一导件577可在第一导槽512中转动和滑动;第二导件579可在第二导槽514中转动和滑动。如此,操作件568可围绕移动的转动轴线转动。在这里,移动的转动轴线垂直于输出轴34的轴线X1,即垂直于轴向。优选的,移动的转动轴线垂直于中心平面。移动的转动轴线在垂直于移动的转动轴线的平面内线性移动。在本实施例中,线性移动的轨迹为弧线。因此,操作件568即有转动又有线性移动,相对于安装座572复合运动。但在本实施方式中,操作件568并非通过翻转运动实现驱动件570与夹紧单元540配合和脱开。而是仅需要倾斜一定的角度就可以实现驱动件570与夹紧单元540配合和脱开(可参见图24和图25)。
在操作件568和壳体32之间设有保持机构580。保持机构580包括设置在操作件568上的第一保持件581、设置在壳体32上的第二保持件583。第一保持件581和第二保持件583相互配合,可将操作件568相对壳体32保持在初始位置。具体操作时,只需抬起操作件568,使进而带动驱动件570与夹紧单元540配合。
在安装座572和操作件568之间设有弹性元件526,弹性元件526提供促使操作件568带动驱动件570朝着与夹紧单元540配合的位置的运动弹簧力。如此,在需要更换工作头时,只需操作者抬起操作件568,使第一保持件581脱开第二保持件583的配合,操作件568在弹性元件的作用下,可自动朝着与夹紧单元540配合的位置的运动。具体的,安装座572上设有定位销528,弹性元件526一端卡设在定位销528上,另一端卡设在第二导件579上。
在本实施方式中,夹紧单元540的结构基本同第四实施方式,包括围绕平行于轴向41的轴线可枢转地锁紧件558、与锁紧件558螺纹配合的锁定件560。锁紧件558上设置有与驱动件570配合的配合部582。配合部582包括设置在锁紧件558周向上的若干对称设置的配合面。优选的,与驱动件570配合的配合面的个数为偶数。且这些若干配合面在垂直于轴向41的平面内的投影形成边数为偶数的正多边形。优选的,配合面的个数为6个或8个等。在本实施方式中,配合面的个数为6个。也就是说,锁紧件558为加长的六角螺母,与锁定件560(螺栓)螺纹连接。
而在本实施方式中,驱动件570的具体的结构与第四实施方式有所区别。 具体可参见图27,操作件568设有内腔,驱动件570固定设置在操作件568的内腔内。驱动件570包括设置在操作件568内腔内的若干个驱动面。正对两个驱动面之间的距离与正对两个配合面之间的距离相等,如此,驱动件570就可以带动锁紧件458一起围绕轴线X1转动。优选的,配合面的个数为偶数。优选的,配合面的个数为2个或4个等。在本实施方式中,配合面的个数为2个。
具体操作,请参考图24,操作组件542位于初始位置。操作件568贴合在壳体32的顶部,此时,保持机构580将操作件568相对壳体32保持在初始位置。操作件568处于初始位置时,锁紧件558上的配合部582虽然突伸出安装座572的上表面,但与驱动件570在轴向41上错开,两者脱开配合,操作组件542处于脱开模式。
抬起操作件568,使第一保持件581脱开第二保持件583的配合,操作件568在弹性元件的作用下,可自动朝着与夹紧单元540配合的位置的运动。同时,第一导件577在第一导槽512内转动和滑动,第二导件579在第二导槽514内转动和滑动,从而,操作件468运动至配合位置,如图25和图27所示。此时,驱动件570的两个正对的驱动面卡设在配合部482的两正对的配合面,可带动锁紧件558一起转动,使锁紧件558和锁定件560螺纹锁紧或松开。从而实现安装或更换工作头。显然,当安装或更换工作头完成后,再推动操作件568,压缩弹性元件526,并使第一保持件581与第二保持件583配合,使操作件568扳回并保持在初始位置。
尽管发明人已经对本发明的技术方案做了较详细的阐述和列举,应当理解,对于本领域技术人员来说,对上述实施方式作出修改和/或变通或者采用等同的替代方案是显然的,都不能脱离本发明精神的实质,本发明中出现的术语用于对本发明技术方案的阐述和理解,并不能构成对本发明的限制。
