为了清楚的说明本申请的技术方案,在说明书附图中定义上侧、下侧、左 侧、右侧、前侧和后侧。
如图1至图2所示的斜锯100,该斜锯100包括底座13、工作台12、切割机构11、延伸机构15以及第一锁定机构14。
底座13用于支撑工作台12,也即用于支撑整个斜锯100,斜锯100可以通过底座13平稳的放置于地面或者是操作平面上。具体的,底座13位于工作台12的下方,切割机构11位于工作台12的上方。
切割机构11包括切割组件111、机架113和导轨组件112。切割组件111包括切割件111b和电机。切割件111b用于实现斜锯100的切割功能,其具体为圆锯片。电机用于提供动力来源,能驱动切割件111b在一个切割平面S内旋转,从而实现切割件111b对放置于工作台12上的工件进行切割。
在本实施例中,切割组件111还包括一个连接切割组件111和导轨组件112的第一连接件111c,且切割组件111枢转连接至该第一连接件111c处。即切割组件111能绕工作轴线102转动,以使切割件111b逐渐靠近工件进行切割作业或在切割作业完成后逐渐远离工件。
在本实施例中,切割组件111还包括至少部分覆盖切割件111b的护罩111a。为满足安全需要,护罩111a还包括固定连接的第一护罩和相对于第一连接件111c转动的第二护罩。其中,第一护罩始终包围至少部分切割件111b,在未切割状态下,第二护罩能包围至少部分切割件111b并避免切割件111b暴露在使用者能直接触碰到的范围内。当使用者操作切割组件111围绕工作轴线102转动并逐渐靠近工件进行切割作业时,第二护罩可随使用者操作切割组件111而逐渐朝远离工作台或者远离切割件111b的方向转动,从而使得切割件111b能接触工件进行切割。可以理解的,护罩111a也可以固定连接至第一连接件111c。护罩111a下端与工作台12接触之处还设有行走轮,辅助护罩111a在工作台12的前后移动。
导轨组件112设置在机架113的上,导轨组件112包括滑轨1121。机架113形成有供导轨组件112穿过的通孔,通孔具有一定深度。滑轨1121穿过上述通孔1331设置。滑轨1121一端设有止挡件,防止导轨组件112脱离通孔,另一端固定连接第一连接件111c。具体的,导轨组件上还连接有可供滑轨1121复位的复位件,该复位件可以是弹簧。
如图1至图11所示,工作台12上还形成有一个贯穿自身的第一通道121,第一通道121在切割平面S内延伸。第一通道121的第一端位于工作台12的内部,第一通道121的第二端延伸至工作台12的外部,该外部即切割组件111的前端。该第一通道121可供切割件111b切破工件时通过并至少部分容纳至第一 通道121中部形成第一容纳腔122内。工作台12和第一通道121的第二端为护罩111a的行走轮提供支撑。行走轮在第一容纳腔122的两侧运动,在第一通道121上靠近第一容纳腔122的边缘处设有定位槽125。具体的,该定位槽125设于第一通道121的第二端,即设于第一通道121伸出工作台12的部分。定位槽125形状与行走轮形状一致,使得护罩111a上的行走轮在运动到该位置时恰好进入定位槽125,此时切割件111b位于第一通道121的中部,同时操作第二操作件112b锁紧导轨组件112。
在工作台12与第一通道121相反方向的一侧设有支撑座123,即该支撑座123设于切割组件111的后端。具体的,支撑座123连接机架113,且机架113能够支撑并带动切割机构相对于工作台12绕第一轴线101转动。在本实施例中,第一轴线101位于切割平面S内,工作台12、第一通道121以及支撑座123结构均相对于第一轴线101对称,第一通道121也沿该第一轴线101延伸。
机架113依次包括相互连续的第一枢转部113a、延伸部113b和第二连接件113c。第一枢转部113a与支撑座123枢转连接,用于传递机架113的转动。延伸部113b相对于工作台12向上方延伸,连接第一枢转部113a和第二连接件113c。第二连接件113c形成有通孔112a。在一些实施例中,第二连接件113c在前后方向的宽度大于延伸部113b的宽度,使得第二连接件113c的前端与支撑座的前端在前后方向大致位于同一竖直平面内。换句话说,第二连接件113c、延伸部113b和支撑座123可以围成一个容纳空间,第一锁定机构14大部分设于该容纳空间中。第二连接件113c的下方形成支架113d,支架113d位于该容纳空间内,第一锁定机构14大部分结构被安置在该支架113d内。
第一锁定机构14至少包括第一状态、第二状态和第三状态。第一锁定机构14为第一状态时,能锁定切割机构相对于工作台以第一轴线101为轴的转动,以使切割机构相对于支撑座123静止。第一锁定机构14为第二状态时,切割机构相对于工作台以第一轴线101为轴的转动,切割机构相对于支撑座123转动。第一锁定机构14为第三状态时,第一锁定机构14能与支撑座123配合以对切割机构的转动进行定位,换句话说,第一锁定机构14为第三状态时,切割机构能在设定位置停止沿一个方向的转动。具体的,切割机构可沿另一方向继续运动,该停止运动的点为定位点,或者切割机构可以在一定范围内活动,此时具有两个相接近的定位点。
第一锁定机构14包括第一操作件141、定位销142和传动轮143。第一操作件141传动连接传动轮143,传动轮143传动连接定位销142。第一操作件141通过第一转轴145传动连接传动轮143。第一操作件141和传动轮143均绕第一转轴145中心的第三轴线104旋转。第一操作件141通过第一转轴145将传动 轮143旋转所需的动力传递至传动轮143。第一操作件141在外力作用下在第一位置、第二位置和第三位置间运动,如图6、7、8所示。应当注意的是,上述第一位置、第二位置或第三位置并不一定仅限制为图中所示的位置,图中所示的位置为本实施例中实现第一锁定机构14状态的极限或临界位置,只要当第一锁定机构14能够实现上述状态所描述的功能时,即可认为其已经到达相应位置,该位置也可能为图中所示第一位置、第二位置或第三位置之间的位置。
第一操作件141位于第一位置时,第一锁定机构14为所述第一状态,如图6所示。传动轮143为异形凸轮结构,包括凸出的第一传动部143a和第二传动部143b。第一传动部143a和第二传动部143b在传动轮143上的位置不同,即第一传动部143a和第二传动部143b朝向不同的方向凸出。传动轮143后侧设有第一锁紧部115,即第一锁定机构14和机架113之间设有第一锁紧部115。第一锁紧部115为具有一定摩擦系数的摩擦片。在本实施例中,支撑座123和机架113之间还设有锁紧板114。锁紧板114上具有刻度,用于辅助切割机构的定位。当第一操作件141运动到第一位置时,第一操作件141沿第一方向106转动,带动传动轮143沿第一方向106运动。随着第一操作件141朝向接近第一位置的位置运动时,该第二传动部143b逐渐挤压第一锁紧部115,使第一锁紧部115逐渐贴紧锁紧板114,即是说使得锁紧板114贴紧机架113的内部结构,使得机架113与锁紧板114锁紧。当到达切割机构相对于支撑座123静止时,第一操作件141所在位置为第一位置,即第一锁定机构14处于第一状态。在本实施例中,机架113和锁紧板114之间还设有第二锁紧部116,第二锁紧部116同样为具有一定摩擦系数的摩擦片,通过分布在锁紧板114两侧的第一锁紧部115和第二锁紧部116,可进一步提高第一锁定机构14在第一状态下的锁定稳定性。
第一操作件141位于第二位置时,第一锁定机构14为所述第二状态,如图7所示。传动轮143下方间隔设置有定位销142,定位销142在定位位置和非定位位置之间运动。定位销142的上端包括与第一传动部143a形状和位置对应设置的从动部142b,在定位销142下端设有突出的定位部。定位销142中部贯穿有第二转轴146,定位销能绕第二转轴中心的第四轴线105转动。第一操作件141沿第二方向107转动,带动传动轮143沿第二方向107转动,第一传动部143a对从动部142b进行干涉,在第一传动部143a的干涉下,定位销142沿第一方向106绕第四轴线105转动,当第一操作件141运动到第二位置时,定位销142由定位位置运动到非定位位置。
第一操作件141位于第三位置时,第一锁定机构14为所述第三状态,如图8所示。第三位置在前后方向上介于第一位置和第二位置之间。当第一操作件141位于第三位置时,第一传动部143a不与从动部142b干涉,且第二传动部 143b不挤压第一锁紧部115和锁紧板114,使得定位部142a处于定位位置的同时,切割机构还能够相对于支撑座123转动,此即为第三状态。在本实施例中,第一锁定机构14为第三状态时,第一传动部143a的下边缘和从动部142b的上边缘具有一定间隙或刚刚接触,所述刚刚接触的情形为两表面相切但第一传动部143a不会对定位销142产生转动的作用力。同理的,第一锁定机构14为第三状态时,第二传动部143b的一侧表面和机架113内壁具有一定间隙或刚刚接触,所述刚刚接触的情形为两表面相切但第二传动部143b不会对机架113后方的第一锁紧部115产生挤压的作用力。
支撑座123上还设有与定位销142配合的若干定位块124。在本实施例中,定位块相对于支撑座123的表面向外凸出,由于切割机构需要转动,支撑座123的上表面被配置为圆弧形,表面的不同位置设有定位块124,以满足机架113转动到不同位置时,定位销142可以被不同位置的定位块124限位。在本实施例中,定位块124的左侧壁与定位销142接触,该定位销142的左侧壁(或定位块124的左侧壁)到支撑座中心所连直线与工作台所在平面形成夹角α,该夹角即为定位块124的安装角度,α也为切割机构的转动定位角度,α取值包括但不限于30°、45°、60°、90°、12°、135°、15°等常用切割角度。在其他实施例中,定位块124设为可拆卸或可转动调节的结构,根据使用者需求对定位角度进行调整。
如图9所示,第一转轴145的两端固定在支架113d上,其中一端部分伸出支架113d,伸出的部分固定连接第一操作件141,传递第一操作件141的运动。上述伸出部分包括第一固定部145a和第二固定部145b。第一操作件141包括操作部141a和固定孔141b。第二固定部145b对应连接固定孔141b,第一固定部145a在固定孔141a中穿过,与固定件147连接,使得第一操作件141和第一转轴145稳定连接。固定件147的外径大于固定孔141b的直径。固定孔141b和第二固定部145b的截面呈腰形或扁位形。
第一锁定机构14还包括偏压元件144,偏压元件144用于将定位销142由非定位位置复位至定位位置。具体的,偏压元件144为金属弹片,偏压元件144具有第一端和第二端,第一端越过传动轮143固定连接至机架113,第二端通过紧固件148与定位销142的上端固定。在一些实施例中,定位销142包括转动部142d和第三连接件142c。转动部142d套设在第二转轴146外,使得定位销142可以相对于支架113d转动。第三连接件142c连接转动部142d,并与从动部142b分别位于转动部142d的轴向上的不同位置,更利于传动轮143的传动部与从动部位置的设置,保证第一锁定机构的紧凑性。在一些实施例中,第三连接件142c和从动部142b在转动部142d的径向方向上也沿不同方向延伸。在本实施例中,第三连接件142c至少设有两个,上述第三连接件142c分别在第三轴线 104方向上位于从动部142b的两侧,保证复位的稳定性。在一些实施例中,两个第三连接件142c分别连接两个偏压元件144的第二端。在一些实施例中,两个偏压元件144的第一端呈一体结构。当定位销142在传动轮143作用下向上转动至非定位位置时,第三连接件142c挤压或扭转偏压元件144,当传动轮143的干涉作用力消失后,在偏压元件144的作用下定位销142回到定位位置。
如图11所示,切割机构还设有用于对工件进行导向的导向组件16,导向组件16设置在护罩111a上,并与切割件111b间隔设置。在其他实施例中,导向组件16可设置于靠栅或工作台等位置。导向组件16包括枢转连接的导向活动件161和导向固定件162。具体的,导向固定件162与护罩111a固定连接,导向固定件162包括枢接孔162a,导向活动件161包括第二枢转部161a。第二枢转部161a和枢接孔162a通过第三转轴163枢转连接,使得导向活动件161可绕第三转轴163相对于导向固定件162转动,导向活动件161具有第一位置和第二位置,如图11所示的为第一位置。导向组件16还包括第一弹性件164,第一弹性件164一端连接导向活动件164,用于提供使导向活动件164的复位的作用力。在第一弹性件164的自然状态下,导向活动件161位于第一位置。在本实施例中,导向活动件161的第一位置被配置为相对于水平面向下倾斜或者平行于水平面。导向活动件161的第二位置为导向活动件161挤压第一弹性件164而向上转动后的位置,第二位置的具体高度由工件的高度决定。在本实施例的斜锯100的使用过程中,对于高度较高的工件,作业时工件放置的稳定性较差,通过设置导向组件,当工件沿切割件111b运动时,工件的上表面接触导向活动件161,在操作人员的推力作用下,导向组件向上转动,被挤压的第一弹性件164使得导向活动件161始终具有一个向下的压紧力,保证工件稳定性。
在一些实施例中,导向活动件161包括一个与第二枢转部161a连接的平直面、L形台面或者阶梯形面,包括但不限于上述结构。上述结构使得导向活动件161至少具有与工件接触的一个平面或一条边。导向固定件162固定在第一护罩上。导向固定件162还具有调高装置,能够根据工件高度调整所在位置。
如图1所示,工作台12的外侧设有延伸机构15。具体的,延伸机构15大致地关于切割平面S对称设置。延伸机构15包括辅助支撑件152、第一滑轨151以及延伸台155。辅助支撑件152与第一滑轨151连接,并沿滑轨运动。第一滑轨151由连续的横向滑轨151a和纵向滑轨151b连接形成。具体的,横向滑轨151a和纵向滑轨151b沿不同方向延伸,并在一点连接成L形。为了保证辅助支撑件152滑动的顺畅,连接成L形的连接处成弧形。辅助支撑件152至少具有第一支撑面和第二支撑面,上述支撑面能给超出工作台尺寸的工件提供支撑。具体的,辅助支撑件152运动到纵向滑轨151b上时,其第一支撑面与横向滑轨151a的表面平齐,辅助支撑件152为滑轨表面的延伸面提供支撑。辅助支撑件 152运动到横向滑轨151a上时,其第一支撑面与靠栅相配合,为工件提供倾斜等姿态的支撑,如图14所示。在一些实施例中,辅助支撑件152还包括不同于第一支撑面的第二支撑面,该第二支撑面用于对待切割工件进行限位,可将工件切割成固定长度(约为工作台直径的二分之一)。当辅助支撑件152位于工作台12左侧时,第二支撑面为辅助支撑件152右侧端面,工件从右侧进入工作台12,在工件端部抵达辅助支撑件152的第二支撑面时,运行切割机构完成切割,则工件可切割为给定长度。基于此,该辅助支撑件152还可从第一滑轨151上拆卸下来,作为延伸组件的第三状态,安装至靠栅126前侧,在靠栅126前侧完成上述限位定位的功能,进一步将工件的设定切割长度缩短。在其他实施例中,辅助支撑件152还可以自转,将辅助支撑件152的第二支撑面旋转到抵靠工件的一侧,该第二支撑面的曲率、斜率或者表面形状不同于第一支撑面,以使支撑件对于工件具有不同的支撑方式。
辅助支撑件152包括与第一滑轨151连接的滑杆157、第一支撑部154a以及第一把手154b,滑杆157包括滑动端157b和固定端157a,滑动端157b直径大于固定端157a直径,滑动端157b嵌入至第一滑轨151内,固定端157a连接支撑座154a。滑杆157主体呈圆柱形,以保证辅助支撑件152在第一滑轨151上的自转。第一支撑部154a构成辅助支撑件152的主体部分,具有第一支撑面和第二支撑面。第一支撑部154a与固定端157a固定连接,第一支撑部154a在上述连接处相反的一侧设有第一把手154b,用于操纵辅助支撑件152的运动。
辅助支撑件152和第一滑轨151的组合结构被安置在延伸台155上,延伸台155通过伸缩装置156与底座13连接,使得延伸台155能够调整整体宽度以适应工件的需求。延伸台155还包括第二滑轨158,第二滑轨158内设有第二把手153,第二把手153的一端穿过第二滑轨158连接到第一滑轨151,通过操纵第二把手153可使得第一滑轨151的整体在延伸台155的一个平面上滑动,可以延伸支撑的范围。
在相关技术的斜锯中,切割件连接有传动装置,切割件通过传动装置与电机传动,该传动装置部分与切割件同心设置。传动装置中包含有解锁装置,用于接触切割件与切割机构或与传动装置的连接,然后使用人员对切割件进行更换。相关技术中该解锁装置的按键通常包括设于传动装置机壳172上的解锁按键17和弹性体171。一般弹性体171仅提供解锁按键17的复原力,即当操作人员按下时,内部的解锁装置才会处于解锁状态,为了机构配置的简便性,及不影响传动装置的布局,内部一般不会配置有按压的卡和结构,需要使用者长时间保持按压状态以配合解锁。
为了解决上述问题,在本实施例中,按键机壳173上形成有异形槽175,按 键机壳173内设有解锁销174,解锁销174上设有凸出的卡接部174a。异形槽175至少包括朝向不同的两段槽,卡接部174a可以沿异形槽175运动,当其由异形槽175的末尾沿第一段槽运动直到第一段槽和第二段槽交接处时,解锁装置由锁定变为解锁,卡接部174a进入第二段槽后,卡接部174a与第二段槽配合,使得解锁装置维持解锁状态,此时操作者可双手操作拆装切割件。
如图18至图24所示,本实施例公开了一种斜锯,其中与实施例一相同或相应的零部件采用与实施例一相应的附图标记或名称。为简便起见,仅描述实施例二与实施例一的区别点。本实施例的斜锯200与实施例一不同的是第一锁定机构21的结构及位置等。
第一锁定机构21的主体沿第一通道241设置,并在第一通道241的第二端242处露出有第一锁定机构21的第三操作件221和第四操作件231。第一锁定机构21由锁定组件22和止动组件23组成,锁定组件22和止动组件23分别连接第三操作件221和第四操作件231。
如图19所示,锁定组件22包括与第三操作件221连接的传动杆222,使用者操纵第三操作件221的转动,带动传动杆222绕第一直线201转动。传动杆222的第一端连接第三操作件221,传动杆222的第二端设于支撑座内并连接锁紧件。锁紧件包括第一固定件224、锁紧片226、第一弹性件225以及第二固定件227。传动杆222的第二端即远离第三操作件221的一端具有驱动段。在本实施例中,驱动段为螺纹段,该端通过螺纹段依次贯穿并连接第一固定件224、锁紧片226、第一弹性件225以及第二固定件227。具体的,第一固定件224及锁紧片226与支撑座的壳体连接。锁紧片226还与机架连接,锁紧片226上开设有滑槽226a,使得切割机构的转动时传动杆222可以在滑槽226a内滑动。第二固定件227与传动杆222的第二端末端连接,第一弹性件225设于第二固定件225和锁紧片226之间,支撑座的部分壳体设于第一固定件224和锁紧片226之间。当传动杆222沿第一方向202绕第一直线201转动时,在螺纹段的作用下,传动杆222沿第一直线201向斜锯200的前方运动,第二固定件227挤压第一弹性件225,第一弹性件225继续挤压锁紧片225,锁紧片225挤压支撑座壳体至第一固定件224,达到压紧机架和支撑座的目的,使其不能发生相对运动,使得第一锁定机构锁定机架的转动,切割机构达到第一状态。当传动杆222沿与第一方向202相反的方向绕第一直线201转动时,传动杆222沿第一直线201向斜锯200的后方运动,在第一弹性件225的复原力作用下传动杆222更快速的带动第二固定件227远离锁紧片226,完成切割机构的转动运动的解锁,此时切割机构可进入第二状态或第三状态。
锁定组件22还包括设于定位杆222上的离合结构223,用于限制传动杆222 沿第一直线201方向向斜锯200后方的运动,即限制解锁过程的进一步运动。如图21所示,离合结构223包括第一离合件223a和第二离合件223b,第一离合件223a和第二离合件223b分别具有一个相互啮合的表面。具体的,第一离合件223a固定在工作台24下方的壳体上,第二离合件223b与传动杆222固定连接,第一离合件223a和第二离合件223b均具有供传动杆222贯穿的通孔。在一些实施例中,第一离合件223a朝向第二离合件223b的表面设有阶梯状的台阶223c,台阶223c沿第一方向202依次增高,达到一定高度后,形成一个断面223d。第二离合件223b朝向第一离合件233a的表面上也具有与第一离合件233a相啮合的形状。上述两表面至少具有两个台阶223c结构。第二离合件223b中心设有异形孔223e,该异形孔223e是不同于圆孔的通孔,相应的传动杆222上设有凸块,能够卡合至该异形孔223e中,完成第二离合件223b和传动杆222的固定连接。具体的,当第一离合件223a和第二离合件223b啮合后,由于两断面223d的限制,传动杆222沿第一方向202的反方向的转动被离合结构所限制。
锁定组件22还包括设于第二离合件223b前方的连接件229,连接件229和第二离合件223b之间设有第二弹性件228。第二弹性件228的两端分别连接连接件229和第二离合件223b。连接件229套设在传动杆222上,并与传动杆222活动连接,传动杆222可在连接件229之中运动。连接件229还与工作台24的壳体固定连接。当传动杆222沿第一方向202绕第一直线201转动时,传动杆222沿第一直线201向斜锯200的前方运动,锁定组件完成锁紧的同时,第二离合件223b在传动杆222的带动下沿台阶223c运动,直至在第二弹性件228的带动下第二离合件223b与第一离合件223a相互分离。当传动杆222沿与第一方向202相反的方向绕第一直线201转动时,传动杆222沿第一直线201向斜锯200的后方运动,第二离合件223b在传动杆22的带动下与第一离合件223a相互接近,当接近到两表面相啮合并挤压第二弹性件228时,两表面的断面223d相卡和,使得第二离合件223b不能进一步运动,从而限制传动杆222进一步运动,此时到达解锁后的临界状态,保证解锁后切割机构可以停止运动。支撑座的后侧还设有阻尼件,用于给转动的机架提供缓冲。
止动组件23包括与第四操作件231连接的传动件234,在本实施例中传动件234为柔性传动结构,在其他实施例中,也可以为刚性结构。传动件234通过连接杆232和转换部连接到第四操作件231。在本实施例中,转换部为凸轮233,连接杆232和凸轮233用于改变第四操作件231的传动方式和传动方向,使得第四操作件231和第三操作件221可设置在第一通道241的同侧。在其他可替换实施例中,转换部可以为连杆传动结构。
由于第一通道241中间设有第一容纳空间,第一通道241的壳体被分割为 左右两部分,止动组件23和锁定组件22的主体可分别设于两部分内,第四操作件231和第三操作件221设于第一通道241的侧部,连接杆232横向的设置于第一通道241的端部。传动件234主体沿第一通道241延伸,即沿平行于第一直线201的方向延伸。具体的,连接杆232一端连接第四操作件231,连接杆232另一端连接凸轮233。凸轮233能在第四操作件231的带动下绕连接杆232的中轴线即第二直线203转动。传动件234的运动方向与凸轮233的转动所在的平面平行,在本实施例中,传动件234的运动方向与第一直线201平行但相反。传动件234的末端连接有定位销235,定位销235至少部分与支撑座壳体相连,使定位销235只能沿与第一直线201平行的方向运动。定位销235处设有定位块236,定位块236设于机架内,定位块236上设有若干定位孔236a,每一定位孔236a的位置对应机架旋转到不同角度。当第一锁定机构21处于第二状态时,切割机构可以相对于支撑座转动,此时凸轮233向前侧运动时,带动传动件234向前侧运动,进而带动定位销235向前运动,定位销235从定位孔236a中分离,在锁定组件解除对切割机构的转动运动的锁定时,切割机构可以相对于支撑座转动。当第一锁定机构21处于第三状态时,切割机构暂时相对于支撑座静止,不论锁定组件解锁还是锁紧切割机构以第一轴线为轴的转动运动,切割机构均保持静止,此时凸轮233向后侧运动时,带动传动件234向前侧运动,进而带动定位销235向前运动,定位销235进入定位块236上一个定位孔236a内,由于定位销235至少部分与支撑座连接,则可通过定位销将切割机构限位至预定位置,此时只需要操纵第三操作件221锁紧切割机构,即可实现锁切割机构的锁定。
在本实施例中,定位孔236a的形状与定位销235末端的形状一致,使得第一锁定机构为第三状态时,定位后的切割机构基本与第一状态类似。在其他实施例中,定位孔236a可以为弧形孔等异形长孔,该孔的两端分别对应特定的切割角度,使得定位销235能够在一定设定范围内转动,即使得切割机构能够在一定设定范围内转动,在转动到两端部时,分别对应两个设定角度,操作者不需要去斜锯200后方确认刻度即可快速确定所需求的角度范围,结合设于斜锯200前侧的操作件。
斜锯200除了切割机构能够相对于支撑座转动外,其工作台24也能相对于底座25旋转,此结构不限于本实施例。为了便于操作工作台24的旋转,本实施例还包括定位机构26,定位机构26设于工作台24下方,用于操作者转动工作台24,并对工作台24在底座25上的位置进行调整、定位等。定位机构26包括锁紧位置与解锁位置,分别对应工作台24相对于底座25转动的锁紧与解锁。定位机构26包括连接于第一通道241的第二端处的第五操作件261,使用者可以通过第五操作件261带动工作台24运动,并通过第五操作件261带动定位机 构26在锁紧位置与解锁位置之间的运动。
具体的,第五操作件261通过枢接杆262与工作台24壳体连接,使得枢接杆262能够绕一点转动。枢接杆262上连接有第一运动件263,能够在枢接杆262带动下朝同一个方向运动。第一运动件263的第一端设于第五操作件261处,第一运动件263的第二端抵靠于第二运动件264。当第一运动件263转动时,第二运动件264能在其作用下,朝与第一运动件263相反的方向运动,即,当第一运动件263的第二端相对于原始位置向下转动时,第二运动件264远离第一运动件263的一端向上转动。具体的,第二运动件264第一端抵靠在第一运动件263的下方,第二运动件264的第二端连接第一调节件266。第一调节件266为弹性结构,设于第二运动件264的下方,第一调节件266至少部分与第二运动件264的下侧连接。第一调节件266的第一端通过固定件265和工作台24的壳体连接,使其可以以固定件265的连接处作为弹性变形运动的参考点。第一调节件266的第二端位于底座25的第二调节件252的上方,该第二调节件252设有调节工作台在水平方向转动所需的刻度。在一些实施例中,第一调节件266的第二端设有定位部266a,在第二调节件252上设有若干定位槽251,若干定位槽251对应不同的工作台24的旋转角度。具体的,定位部266a向下侧凸起,凸起的形状与定位槽251的形状一致。第一运动件263还包括套设在枢接杆262上的第三弹性件263a,第三弹性件263a的上端在第一通道241的第二端242的附近。当定位机构26位于锁紧位置时,第三弹性件263a的上端和第一通道241的第二端242具有一定间距,当第五操作件261向上运动时,第三弹性件263a的上端逐渐接近第一通道241的第二端242,当定位机构26位于锁紧位置时,第三弹性件263a的上端和第一通道241的第二端242接触并相互挤压,使得第三弹性件263a发生一定形变。当需要解锁时,使用者操作第五操作件261向上运动时,第一运动件263的第二端向下运动,第二运动件264的第二端相应向上运动,带动第一调节件266的第二端向上发生形变,定位部266a离开定位槽252,进而定位机构26离开底座25,此时进入解锁状态,工作台24可相对于底座25旋转,反之则为锁定状态。在其他实施方式中,也可以只设有一个运动件完成上述传动。在其他实施方式中,定位部也可以设置在调解部上,而在第一调节件的末端设置定位槽。
在本实施例中,斜锯200的一侧还设有副台面组件27,副台面组件27与实施例一中的延伸组件类似,可以起到辅助和延伸工作台的支撑功能,本实施例的副台面组件27还具有收纳工件、废料的作用。副台面组件27包括支撑件272、第七操作件271、延伸座273以及伸缩装置。伸缩装置设于支撑件272的下方,连接底座25,使得副台面组件27能够相对于工作台24进行远离或靠近运动。延伸座273设于伸缩装置的导轨上方,在副台面组件27位于原始位置时,延伸 座273一端低靠底座25,一端连接在支撑件272下方。支撑件272的上表面和工作台的上表面位于同一平面内。使得工作台24、延伸座273和支撑件272三者形成凹形结构,即工作台24和延伸座273之间具有间距。该间距内可放置工件,支撑件272的上表面也可作为工件多余出工作台部分的放置面。第七操作件271能够将运动后的副台面组件27锁紧在伸缩装置的导轨上到某一位置。
如图26~28所示,斜锯200包括第二锁定机构28,第二锁定机构28至少部分结构与工作台24固定连接,第二锁定机构28至少部分结构设于工作台24下方,尤其是,部分第二锁定机构28沿第一通道241设置。第二锁定机构28用于对转动后的工作台24锁定,并与定位机构26共同完成对工作台旋转角度的定位。第二锁定机构28包括供使用者操作的第六操作件281,使用者操作第六操作件281运动到第六操作件281的第一位置时,第二锁定机构28完成对工作台24的锁定。使用者操作第六操作件281运动到第六操作件281的第二位置时,第二锁定机构28完成对工作台24的解锁。上述的锁定是指工作台24通过第二锁定机构28实现与底座25的固定,此时工作台24与底座25无法完成相对运动。上述的解锁是指工作台24与底座25无固定连接,工作台24在使用者的作用下可以相对于底座25运动。可以理解的,定位机构26提供的限制力不足以保证工作台24与底座25在切割工作时不发生相对运动,即是说,定位机构26锁紧位置时,可以限制工作台24与底座25之间的相对运动,但当进行切割工作时,容易将定位机构26的锁紧状态破坏。而第二锁定机构28可以提供一种锁定力足够使工作台24与底座25在切割工作稳定保持相对锁定状态。
第二锁定机构28包括制动块282。第六操作件281和制动块282传动连接,制动块282随着第六操作件281的动作而运动。当工作台24和底座25锁定时,制动块282的一个表面与底座25的一个表面紧密接触,并在摩擦力的作用下通过该制动块282将工作台24与底座25锁定。具体的,底座25在工作台24的下方形成一个容纳槽253,容纳槽253具有与制动块282接触的表面,记为第一制动面,对应制动块282的接触面记为第二制动面。容纳槽253设于第二调节件252所在圆周的内侧,且与制动块282接触的表面位于容纳槽253远离第二调节件252的一侧。第一制动面或第二制动面与工作台24所在平面具有夹角β,5°≤β≤90°,在一些实施例中,为15°≤β≤70°。
制动块282与通过传动组件283与第六操作件281连接,传动组件283包括第二传动件283b和第一传动件283a。第二传动件283b一端与第六操作件281连接,另一端连接第一传动件283a。第一传动件283a沿第三直线204延伸,并能在第三直线204的延伸方向上进行运动。在本实施例中,第一传动件283a可以为刚性的杆状结构,也可以是其他结构或组件。该第一传动件283a设于工作台24和底座25之间,一端连接第二传动件283b,另一端连接制动块282。当 第一传动件283a在第三直线204方向上进行运动时,制动块282跟随第一传动件283a在平行或重合于第三直线204方向上运动。尤其是,工作台24和底座25的上表面平行于或大致平行于第三直线204,使得工作台24的主体、第一传动件283a和底座25的上表面相互平行,或者,上述三者两两之间的夹角不超过10°。当第六操作件281在第一位置和第二位置之间运动,其运动路径与第三直线204不平行也不重合时,第二传动件283b用于将第六操作件281对第二传动件283b的作用力方向转换成沿第三直线204的方向,若第六操作件281在第一位置和第二位置之间运动,其运动路径与第三直线204平行或重合时,传动组件283也可以不包含第二传动件283b。
第一传动件283a与工作台24底部的固定结构连接,该固定结构限制第一传动件283a在径向方向上的运动,使得其基本沿轴向方向运动,即沿第三直线204方向运动。在固定结构之间还设有偏压元件284,偏压元件284用于对第一传动件283a的运动提供复位的作用力。
第二锁定机构28包括指针285,指针285跟随工作台24在第二调节件252刻度上运动。具体的,第一传动件283a靠近制动块的一端设有指针285,指针285随第二锁定机构28运动,也即随工作台24转动。指针285末端位于第二调节件252附近,指示于第二调节件252的刻度。由于第二锁定机构285被安装在工作台24壳体的内部,指针285在工作台24中露出。
如图29至图51所示,本实施例公开了一种斜锯,其中与实施例二相同或相应的零部件采用与实施例二相应的附图标记或名称。为简便起见,仅描述实施例三与实施例二的区别点。本实施例的斜锯300与实施例二不同的是控制切割机构相对于工作台旋转和控制工作台相对于底座旋转的结构等。
在本实施例中,斜锯300包括底座31、工作台32、切割机构33、支撑机构34和电源机构70。
支撑机构34包括机架341和导轨组件。电源机构70用于为斜锯300提供电能。在本实施例中,电源机构70为电池包。可以理解的,电源机构70的安装位置并不影响本申请的方案的保护范围,其他替换实施中,在没有其他创造性劳动时,采用等同替换或等效变换的方式所获得的技术方案,均落在本申请的保护范围。电池包配合相应的电源电路,为斜锯300内的相应部件供电。本领域技术人员应当理解,电源机构70并不限于使用电池包的场景,还可通过市电、交流电源,配合相应的整流、滤波和调压电路,实现对斜锯300内的相应部件供电。
工作台32上还形成有一个沿上下方向贯穿自身的第一通道321,第一通道321在前后方向延伸。第一通道的第一端321a位于工作台32的内部,第一通道 的第二端321b延伸至工作台32的外部,该外部即切割机构33的前端。
工作台32位于第一通道的第一端321a的之后的一端为工作台的第一端32a。支撑座35设置在工作台的第一端32a,即该支撑座35设于切割机构33的后端。具体的,支撑座35枢转连接机架341,且机架341能够支撑并带动切割机构33相对于工作台32绕第一轴线301转动。当切割机构33以第一轴线301为轴相对于工作台32进行转动时,可以实现对工件在竖直方向上的倾斜切割。即是说,切割机构33以第一轴线301为轴相对于工作台32进行转动时,切割件131形成的切割平面S与上下方向形成的平面倾斜。
在一些实施例中,第一轴线301位于切割平面S内,切割平面S也以第一轴线301为轴转动。工作台32、第一通道321以及支撑座35结构均相对于第一轴线301基本对称。在本实施例中,第一通道321也沿该第一轴线301方向延伸。
如图29至图41所示,斜锯300还包括第一锁定机构36。第一锁定机构36至少包括:第一状态、第二状态和第三状态。第一锁定机构36处于第一状态时,第一锁定机构36锁紧切割机构33相对于工作台32以第一轴线301为轴的转动;第一锁定机构36处于第二状态时,第一锁定机构36允许切割机构33相对于工作台32的转动;第一锁定机构36处于第三状态时,第一锁定机构36允许切割机构33沿一个预设方向转动至一个设定位置。而当第一锁定机构36离开第三状态时,切割机构33沿一个预设方向转动至该设定位置后所述第一锁定机构36限制切割机构33继续沿预设方向运动而超过设定位置。即是说,第一锁定机构36为第三状态时,能对切割机构33的转动进行定位。换句话说,第一锁定机构36为第三状态时,切割机构33与支撑座35为自由旋转状态,操作者可以操作切割机构33至一个设定位置后,操作第一锁定机构36离开第三状态,第一锁定机构36对切割机构33的转动定位完成。在本实施例中,切割机构33能在设定位置被限位不能沿另一方向转动。在其他可替换实施例中,可沿另一方向继续运动,具体与第一锁定机构36的结构有关。该被限位的“设定位置”可以为点即定位点,或者切割机构33可以在一定范围内活动,此时具有两个相接近的定位点,设定位置即在两个定位点之间。“预设方向”根据操作者的实际需求可以是以第一轴线301轴顺时针旋转,也可以是以第一轴线301的逆时针旋转。
第一锁定机构36包括:操作手柄360,其设置在工作台的第二端32b,用于供操作以切换第一锁定机构36的状态。可以理解的,“工作台的第二端32b”是指与工作台的第一端32a不相同或不同侧的一端,并不限定“工作台的第二端32b”为与“工作台的第一端32a”正相对的一端。在本实施例中,为了方便操作者进行操作,操作手柄360设置在工作台的第二端的一个侧面32b2。在本实施例 中,第一锁定机构36整体基本沿第一轴线301延伸。
操作手柄360至少包括对应第一状态的第一位置、所述第二状态的第二位置和对应第三状态的第三位置;操作手柄360通过沿第一方向F1做往复运动以在第一位置、第二位置和第三位置间切换。在本实施例中,操作手柄360以第二直线302为轴沿第一方向F1进行往复转动以切换第一锁定机构36的状态。其中,在本实施例中,第二直线302与第一轴线301平行或重合。当然,第二直线302与第一轴线301也可以相交。在其他替换实施例中,操作手柄360也可以沿第一方向F1进行直线往复移动,即平移滑动。将操作手柄360在切换第一锁定机构36的至少三个工作状态的运动限制在一个方向内,方便操作者的操作,切换动作更加连续和简单。另一方面,可以实现一个操作手柄360进行三个状态的切换,更加有利于操作者单手操作。为了提高操作者的切换的舒适性,操作手柄360在三个位置切换时,操作手柄360的边缘不超过底座31的底面。这样使得操作者在使用操作手柄360时不会与放置面或地面发生干涉碰撞。
操作手柄360在外力作用下在第一位置、第二位置和第三位置间运动,如图35至图40所示。其中,第二位置位于第一位置和第三位置之间,而且第二位置为初始位置。应当注意的是,上述第一位置、第二位置或第三位置并不一定仅限制为图中所示的位置,图中所示的位置为本实施例中实现第一锁定机构36状态的极限或临界位置,只要当第一锁定机构36能够实现上述状态所描述的功能时,即可认为其已经到达相应位置,该位置也可能为图中所示第一位置、第二位置或第三位置之间的位置。
第一锁定机构36,还包括:锁定组件361和止动组件363。其中,锁定组件361提供锁定切割机构33和工作台32以第一轴线101为轴相对转动的锁紧力。锁定组件361包括提供锁定切割机构33和工作台32相对转动的锁紧力的工作状态和释放锁定切割机构33和工作台32相对转动的锁紧力的释放状态。其中,第一锁定机构36的第一状态即是操作手柄360在第一位置时,锁定组件361处于工作状态。第一锁定机构36的第二状态或第三状态即是操作手柄360在第二位置或第三位置时,锁定组件361处于释放状态。止动组件363,提供多个预设位置并通过操作手柄360选择设定位置后限制切割机构33继续沿预设方向运动。止动组件363包括可以在多个预设位置中进行选择的定位状态,此时切割机构33可以旋转,以及限制切割机构33继续沿预设方向运动超过选择的设定位置的限制状态。第一锁定机构36的第三状态即是操作手柄360在第三位置时,止动组件363为定位状态。在第一锁定机构36离开第三状态即是操作手柄360离开第三位置时,止动组件363限制切割机构33继续沿预设方向运动,止动组件为限制状态。
第一锁定机构36,还包括:驱动组件362,形成或连接于操作手柄360,驱动组件362分别连接锁定组件361和止动组件363。
其中,驱动组件362包括,连接或形成于操作手柄360的第一驱动杆3621、连接锁定组件361的第二驱动杆3622和连接止动组件363的第一传动部3623,其中,第二驱动杆3622连接或形成于第一驱动杆3621,在本实施例中,第二驱动杆3622形成于第一驱动杆3621,第一传动部3623连接或形成于第一驱动杆3621。实现一个操作手柄360进行三个状态的切换,更加有利于操作者单手操作。可以理解的,一个操作手柄360驱动第一驱动杆3621,而第一驱动杆3621分别通过第二驱动杆3622和第一传动部3623对锁定组件361和止动组件363进行控制。
在本实施例中,第一驱动杆3621与操作手柄360直接连接,进而第一驱动杆3621与操作手柄360均以第二直线302为轴进行转动。当然可以理解的,第一驱动杆3621可以与操作手柄360为同一部件。在本实施例中,第一驱动杆3621与第二驱动杆3622也均第二直线302为轴进行转动。
支撑座35与工作台32固定连接,机架341与支撑座35枢转连接。其中,机架341包括枢转部3411,枢转部3411与支撑座35枢接并传递机架341的转动,枢转部3411和支撑座35可以连通以形成一个容纳空间,在本实施例中,此容纳空间为第二容纳空间34a。可以理解的,切割机构33相对于工作台32绕第一轴线301的转动,是通过机架341相对支撑座35绕第一轴线301的转动而实现的。同时,锁定组件361与止动组件363基本设置在第二容纳空间34a内。
如图36至图42所示,锁定组件361包括:第一固定件3611,其与第二驱动杆3622活动连接,且第一固定件3611与支撑座35固定连接。第二固定件3612,与第二驱动杆3622的末端连接。锁紧片3613被第二驱动杆3622贯穿,且设于第一固定件3611和第二固定件3612之间。第一弹性件3614,设置在所述锁紧片3613与所述第二固定件3612之间。在一些实施例中,第二驱动杆3622远离第一驱动杆3621的末端为第二端3622b,第二端3622b具有驱动段。在本实施例中,第二端3622b设置有螺纹段。第一固定件3611及锁紧片3613与支撑座35的壳体固定连接,锁紧片3613还与机架连接,锁紧片3613上开设有滑槽,使得切割机构在转动时第二驱动杆3622可以在滑槽内滑动。第二固定件3612与第二驱动杆3622的第二端3622b固定连接,第一弹性件3614设于第二固定件3612和锁紧片3613之间,支撑座35的部分壳体设于第一固定件3611和锁紧片3613之间。当第二驱动杆3622被操作手柄360带动以第二直线302为轴转动,即是操作手柄360由第二位置转动至第一位置时,在螺纹段的作用下第二驱动杆3622沿第二直线302向斜锯300的前方运动,第二固定件3612挤压 第一弹性件3614并进而挤压锁紧片3613和支撑座35壳体至第一固定件3611,使得锁定组件361锁定支撑座35和机架341的转动,锁定组件361处于工作状态,第一锁定机构36达到第一状态。当第二驱动杆3622被操作手柄360带动以第二直线302为轴沿相反的方向转动时,即是操作手柄360由第一位置转动至第二位置时,第二驱动杆3622沿第二直线302向斜锯300的后方运动,在第一弹性件3614的复原力作用下第二驱动杆3622更快速的带动第二固定件3612远离锁紧片3613,完成对锁定组件361的解锁,锁定组件361处于释放状态,切割机构33的转动运动的释放,此时第一锁定机构36可进入第二状态或第三状态。
锁定组件361还包括,连接第一驱动杆3621和第二驱动杆3622的离合部3615,离合部3615进一步用于限制第一驱动杆3621沿第二直线302方向向斜锯300后方的运动,即限制释放过程的进一步运动。离合部3615与第二实施例中的离合结构223基本相同。
锁定组件361还包括设于离合部3615前方的第二连接件3616,第二连接件3616和离合部3615之间设有第二弹性件3617,第二弹性件3617的两端分别连接第二连接件3616和离合部3615。第二连接件3616套设在第一驱动杆3621上,并与第一驱动杆3621活动连接,第一驱动杆3621可在第二连接件3616内滑动及转动。第二连接件3616与第二弹性件3617的结构与第二实施例中连接件229和第二弹性件228基本相同。
止动组件363包括:定位块3631和定位销3632。其中,定位块3631设于机架341内即是间接与切割机构33连接,可以理解,定位块3631可以直接连接在切割机构33上。定位块3631上设置有多个配合部3631a,在本实施例中,配合部3631a为若干个定位孔,每一个定位孔的位置对应机架341旋转到不同角度。定位销3632连接第一传动部3623,定位销3632基本沿平行于第二直线302的方向往复运动,定位销3632与任一配合部3631a连接后,限制切割机构33继续旋转运动。定位销3632至少部分与支撑座35的壳体相连,使定位销3632只能沿与第二直线302平行的方向运动。
第一传动部3623包括偏心块3623a、柔性连接件3624和第一传动块3626。其中,偏心块3623a连接第一传动块3626和柔性连接件3624。第一传动块3626连接在第一驱动杆3621上,具体的,第一传动块3626套设在第一驱动杆3621上,当第一驱动杆3621旋转时,第一传动块3626与第一驱动杆3621同步旋转。第一传动块3626沿径向延长设置有第一延长部3626a。偏心块3623a的旋转轴3623b连接在工作台32上,以使偏心块3623a的旋转轴3623b只能以偏心轴线3623c为轴摆动,其中,偏心轴线3623c平行于第二直线302。偏心块3623a的 旋转轴3623b的两侧分别设置有第一偏心部3623d和第二偏心部3623e的长度方向是在左右方向的平面内的。其中,第一偏心部3623d和第二偏心部3623e均沿垂直于第二直线302的方向延伸,即是说,第一偏心部3623d与第二偏心部3623e的夹角大于90°小于380°。第二偏心部3623e连接柔性连接件3624,在本实施例中,柔性连接件3624为钢丝绳。第一偏心部3623d与第一延长部3626a选择性连接。第一延长部3626a与偏心块3623a改变第一驱动杆3621的传动方向。柔性连接件3624通过多个第一固定结构3625将其滑动连接在工作台32上,具体的安装在第一通道321的一侧。柔性连接件3624的一端连接第二偏心部3623e,另一端连接定位销3632。
当第一锁定机构36的第三状态即是操作手柄360在第三位置时,止动组件363处于定位状态,如图41-42所示。第一驱动杆3621旋转使第一传动块3626与第一驱动杆3621同步旋转。第一延长部3626a下压第一偏心部3623d使偏心块3623a旋转。进而第二偏心部3623e向上转动,第二偏心部3623e带动柔性连接件3624向后滑动,柔性连接件3624带动定位销3632沿第二直线302平行的方向向后运动,定位销3632与定位块3631脱离。此时,操作切割机构33运动,即是操作定位块3631旋转。当操作切割机构33旋转至所需角度时,使操作手柄360反向运动到第二位置时,第一延长部3626a反向运动进而不再下压第一偏心部3623d,偏心块3623a复位旋转,第二偏心部3623e向下转动,定位销3632沿第二直线302平行的方向向前运动,定位销3632与定位块3631连接,从而定位销3632进入定位块3631上之一的定位孔内,由于定位销3632至少部分与支撑座35连接,则可通过定位销3632将切割机构33定位至设定位置。
在其他实施例中,定位孔可以为弧形孔等异形长孔,该孔的两端分别对应特定的切割角度,使得定位销3632能够在一定设定范围内转动,即使得切割机构33能够在一定设定范围内转动,在转动到两端部时,分别对应两个设定角度,操作者不需要去斜锯300后方确认刻度即可快速确定所需求的角度范围。
因此,在控制切割机构相对于工作台旋转时过程为:操作手柄360处于第二位置时即初始位置时,锁定组件361处于释放状态,此时,止动组件363中的定位销3632插入定位块3631内。将操作手柄360运动到第三位置,锁定组件361处于释放状态,止动组件363中的定位销3632脱离定位块3631,即是说,止动组件363处于定位状态。此时,切割机构33被操作可以相对于工作台32绕第一轴线301的自由转动。当操作切割机构33旋转至所需角度时,使操作手柄360反向运动离开第三位置,在本实施例中,为到达第二位置时,止动组件363中的定位销3632插入定位块3631内,切割机构33的转动即被限制在旋转至所需角度的设定位置。在本实施例中为切割机构33无法再转动,在其他实施例中,也可以为切割机构33在原旋转方向上,超过设定位置继续运动,也就是 说设定位置为切割机构在原旋转方向上运动的极限位置。当操作手柄360继续运动至第一位置时,锁定组件361处于锁定状态,切割机构33相对于工作台32绕第一轴线301的转动被稳定锁定。切割机构33可以进行切割工作。
如图29至图30和图43至图51所示,斜锯300除了切割机构33能够相对于工作台32转动外,其工作台32也能相对于底座31旋转,其目的是为在工件上形成斜切口。工作台32相对于底座31的旋转轴线为斜切轴线303,在本实施例中,斜切轴线303沿上下方向延伸,具体的,斜切轴线303垂直于第一轴线301。
如图43至图51所示,斜锯300还包括:斜切角的锁定机构、定位机构38和操作机构39。其中,斜切角的锁定机构,提供锁定底座31和工作台32相对转动的锁紧力,在本实施例中,为方便区分,设定斜切角的锁定机构为第二锁定机构37。定位机构38,提供多个预设位置并可选择的将工作台32相对于底座31限制在所选择的预设位置。操作机构39,供握持及操作以使工作台32相对于底座31转动。其中,操作机构39包括:第一操作部39a,通过第一传动组件392驱动第二锁定机构37提供锁紧力。第一操作部39a,包括:对应锁定底座31和工作台32相对转动的第一位置和对应释放底座31和工作台32相对转动的第二位置。第二操作部39b,位于与第一操作部39a可单手同时操作的范围内;通过第二传动组件394驱动定位机构38,以释放工作台32与底座31之间在预设位置的限制。第二操作部39b相对于第一操作部39a包括:对应将工作台32与底座31限制在预设位置的第三位置和对应释放定位机构38对工作台32与底座31限制的第四位置。其中,“可单手同时操作的范围”为:操作者握持并可以向第一操作部39a施加操作力时或后,第二操作部39b在同一只手的至少手指可以触及到并施加操作力的范围。如此,将第一操作部39a和第二操作部39b均设于单手可操作范围内后,便可通过握持操作机构39的单手触及并操作操作机构39上的第一操作部39a和第二操作部39b,不需要通过另一只手配合,可以实现单手即可以控制工作台32相对于底座31的旋转,操作较为便捷。
在本实施例中,第一操作部39a和第二操作部39b连接为一个整体部件,但第一操作部39a和第二操作部39b通过两个传动组件控制第二锁定机构37和定位机构38,传动组件不相互干扰,通过相互独立的两个传动组件分别控制工作台32与底座31转动的锁定和定位,控制更加准确。
在本实施例中,第二锁定机构37、定位机构38和操作机构39也均基本沿第一通道321的长度方向延伸。具体的,沿平行于第一轴线301方向延伸。第二锁定机构37、定位机构38、第一传动组件392和第二传动组件394的大部分均设置在工作台32的下方。第一操作部39a和第二操作部39b连接在工作台的 第二端32b的前侧32b2,即是说,第一操作部39a和第二操作部39b与操作手柄相对于工作台32设置在同一端。而为了方便使用者操作,第一操作部39a和第二操作部39b与操作手柄相对于工作台32设置在同一端的不同位置。
在本实施例中,第一操作部39a,包括:第一板柄391,在具体操作时,操作者握持第一板柄391,并使第一板柄391在在第一位置和第二位置间运动。第二操作部39b,包括:第二板柄393,设置在第一板柄391上,在具体操作时,操作者握持第二板柄393并使第二板柄393在第三位置和第四位置间运动。具体的,第一板柄391以第三直线305为转轴旋转连接在工作台的第二端32b的壳体上。在本实施例中,第三直线305与第一轴线301垂直或相交。第一板柄391整体呈偏平板状,其尺寸适合成年人单手握持。第一板柄391中部形成第三容纳空间391a,第二板柄393设置在第三容纳空间391a中。第二板柄393以平行于第三直线305的第四直线306为转轴旋转。第二板柄393设置在第一板柄391手掌相对的面上,可以理解的,当操作者握持第一板柄391时,第二板柄393同时被操作者握持在手中。所以,第一板柄391被操作在第一位置和第二位置间切换时,第二板柄393由于在第一板柄391上,所以也会与第一板柄391共同在运动。也可以理解为,第一板柄391运动时必然会带动第二板柄393一同运动。第二板柄393可以相对于第一板柄391运动,即第二板柄393以第四直线306为轴运动,以使第二板柄393相对于第一板柄391在第三位置与第四位置间切换。
如图48所示,当第一板柄391在第二位置时,第一板柄391为初始位置。此时,第二锁定机构37释放底座31和工作台32相对转动的第二位置。第二板柄393的初始位置为第三位置,具体的,第二板柄393相对第一板柄391的第三位置为第二板柄393超出第一板柄391,即是说,第二板柄393更靠近操作者手的握持位置。第二板柄393的第四位置相对于第三位置,第二板柄393更靠近第一板柄391。为方便操作者操作,第四位置是第二板柄393与第一板柄391相对手握持的面平齐,此时释放定位机构38对工作台32与底座31相对旋转的限制。
所以当操作者握持操作机构39时,即握持第一板柄391时,会先将第二板柄393由第三位置切换至第四位置。如图49所示,此时第一板柄391处于第二位置,第二板柄393处于第四位置,那么对应第二锁定机构37处于释放锁紧力同时定位机构38处于释放定位限制的状态。操作者即可以通过操作机构39旋转工作台32,使工作台32相对于底座31旋转。当旋转至适当位置时进而需要将工作台32和底座31在此位置进行限制,操作者在握持动作时稍微放松握持以释放第二板柄393,以使第二板柄393超出第一板柄391,此时第二板柄393处于第三位置,定位机构38将工作台32与底座31限制在预设位置。可以理解 的,定位机构38提供的限制力不足以保证工作台32与底座31在切割工作时不发生相对运动。当需要将工作台32与底座31的相对旋转锁紧时,操作第一板柄391使其运动到第一位置,如图50所示。第二锁定机构37提供锁紧力,将工作台32和底座31的相对旋转锁紧。此时第二板柄393处于的位置并不影响第二锁定机构37提供锁紧力。
为使第一板柄391能够保持在第一位置,第一操作部39a还包括形成或连接在所述第一板柄391上的第一限位结构3912。第一限位结构3912为凸轮结构,设置在第一板柄旋转轴3911的后方。此凸轮结构一方面利用凸轮结构上最远端向近端运动时需要外力作用而可以形成止点D进行限位,另一方面利用凸轮可以将旋转运动转化为直线往复运动进而带动第一传动组件392控制第二锁定机构37。可以理解的,此结构不限于本实施例,具体结构只要可以实现必须在外力作用在可以将第一板柄391从第一位置运动至第二位置,将第一板柄391的旋转运动转换为直线往复运动皆可以理解为与本申请相似的实施方式。同时,以上两种功能可以由一个部件实现也可以由两个部件分别实现。
第一传动组件392包括第一驱动部3921和第一传动杆3922。其中,第一驱动部3921与第一限位结构3912可选择性接触,第一传动杆3922连接在第一驱动部3921上。第一驱动部3921将第一板柄391的旋转运动转化为第一传动杆3922的往复移动。第一传动杆3922连接第二锁定机构37,第一传动杆3922为刚性结构并能在第一操作部39a和第二锁定机构37之间往复移动,进而驱动第二锁定机构37提供锁定力。第一驱动部3921为弹性变形部件,具体的,第一驱动部3921为弹性片体。第一驱动部3921沿垂直与第一轴线301方向安装在第一板柄391后侧。第一驱动部3921安装在工作台32上,其安装点可以作为其弹性形变的参考点。当第一板柄391由第二位置切换至第一位置时,第一限位结构3912的凸轮结构与第一驱动部3921的接触由小直径位置变为大直径位置,第一驱动部3921沿第一轴线301向后变形,带动第一传动杆3922向后移动。当第一板柄391至第一位置时,凸轮结构的最远端与第一驱动部3921接触且接触面更靠近位于最远端运动下游侧的小直径面。即是说,当第一板柄391至第一位置时,凸轮结构与第一驱动部3921的接触在凸轮结构的止点D的后方,所以第一板柄391保持在第一位置,持续使第一驱动部3921保持在沿第一轴线301向后变形的状态,所以第二锁定机构37持续提供锁紧工作台32和底座31的锁紧力。当第一板柄391由第一位置向第二位置切换时,第一限位结构3912的凸轮结构与第一驱动部3921的接触由大直径位置变为小直径位置,或由接触变为不接触,此时第一驱动部3921弹性复位,向前复位运动,带动第一传动杆3922向前移动。第二锁定机构37释放锁紧工作台32和底座31的锁紧力,进而解锁工作台32与底座31的旋转。
在本实施例中,第一传动杆3922沿第一轴线301方向往复运动。第一传动杆3922连接在工作台32上,进而限制第一传动杆3922沿上下方向的运动,减少第一传动杆3922的运动分力。在本实施例中,第二锁定机构37由第一传动杆3922与底座31组成。第二锁定机构37需要提供锁紧力时,第一传动杆3922沿第一轴线301方向抵紧底座31,通过二者之间的摩擦力限制底座31。在其他替换实例中,可以通过与第二锁定机构37连接以及底座31连接的两个部件组成第二锁紧机构。由于第二锁紧机构属于相关技术,在其他实施例中均有揭示,本实施例中只揭示其中一种,在此不再赘述。
第二传动组件394包括第二传动部3941,第二操作部39b的驱动力通过第二传动部3941带动定位机构38发生形变。第二传动部3941至少部分包括柔性结构,以使第二传动部3941在外力作用下发生形变。在本实施例中,第二传动部3941为钢丝绳,或第二传动部3941的部分由钢丝绳组成。使用柔性结构使得第二传动部3941在连接第二操作部39b和定位机构38时装配不受限制。柔性结构可以根据装配路径进行形变对装配的精度要求降低。第二传动部3941的一端连接在第二板柄393的后端。具体的,钢丝绳的一端穿过第二板柄393的后端之后固定。第二传动部3941的另一端连接定位机构38。
定位机构38包括第一调节件381。第一调节件381为弹性结构,第一调节件381连接在第二传动部3941的另一端,具体的,设于第二传动部3941的下方。第一调节件的第一端381a通过第二固定结构383和工作台32的壳体连接,使其可以将第二固定结构383的连接处作为弹性变形运动的参考点。第一调节件的第二端381b位于底座31的第二调节件311的上方,该第二调节件311设有调节工作台32在水平方向转动所需的刻度。进一步的,第一调节件的第二端381b设有定位件382,在第二调节件311上设有若干定位槽3112,若干定位槽3112对应不同的工作台32和切割机构33的旋转角度。具体的,定位件382向下侧凸起,凸起的形状与定位槽3112的形状一致。
如图43至图44和如图48所示,当第二板柄393处于第三位置时,定位件382连接至定位槽3112中,或定位件382接触第二调节件311而在定位槽3112附近,继续旋转工作台32,定位件382即可进入定位槽3112中。当第二板柄393处于第三位置时,第一调节件381不发生弹性形变或即是发生弹性形变但形变量不足以使定位件382离开定位槽3112。如图49所示,当第二板柄393由第三位置向第四位置切换时,第二板柄393以第四直线106为转轴旋转,进而带动第二传动部3941向远离底座31的方向运动。在本实施例中,第二板柄393的在连接第二传动部3941的位置设置有凸轮结构,进而在第二板柄393的旋转运动转化为第二传动部3941的直线往复运动。通过第二固定结构383的引导,第二传动部3941连接第一调节件的第二端381b的部分基本垂直于第一调节件 的第二端381b,并位于第一调节件的第二端381b的上方。第二传动部3941向远离底座31方向运动时,第二传动部3941连接第一调节件的第二端381b的部分向上运动,带动第一调节件的第二端381b向上发生形变,定位件382离开定位槽3112,进而调节组件离开底座31,此时进入释放状态,工作台32可相对于底座31旋转。当操作者释放对第二板柄393的握持时,为使第二板柄393能从第四位置自动复位到第三位置,第二操作部39b设置有偏压元件,向第二板柄393提供从第四位置复位至第三位置的偏压力。在本实施例中,偏压元件(图中未示出)为连接第一板柄391和第二板柄393上的扭簧。在其他可替换实施例中,也可以不设置偏压元件,靠第一调节件381的弹性复位力将第二板柄393驱动由第四位置回到第三位置。
操作机构39,还包括:限位组件395,用于使第二板柄393保持在第四位置。可以理解的,在实际操作时需要将定位机构38的限制功能暂时取消的情况。此时,使用限位组件395将第二板柄393保持在第四位置,就可以使定位机构38的限制被保持释放。限位组件395包括,设置在第二操作部39b上的第一限位部3951和与第一限位部3951配合设置在所述第一操作部39a的第二限位部3952。在本实施例中,第一限位部3951为设置在第二板柄393上侧壁上的槽或者卡扣,第二限位部3952为设置第一板柄391侧壁上与卡扣相配合的槽或者卡扣。当需要将第二板柄393保持在第四位置时,就继续按压第二板柄393,第一限位部3951与第二限位部3952相互卡合,将第二板柄393锁定。此时第二板柄393位于低于第四位置的第五位置。当需要解除限位时,反向拨动第二板柄393,第一限位部3951与第二限位部3952的卡合松开,限位解除。在其他实施例中,第一限位部3951与第二限位部3952的具体结构不限于卡扣限位,只要可以相互配合从而限制相对运动并可通过外力解除即可。
为了使第二传动部3941更方便安装,选取第二传动部3941的长度时,第二传动部3941连接第二板柄393与第一调节件381所用的长度大于第二板柄393与第一调节件381之间的实际长度。通过设置在第二传动部3941一端的张紧第二调节件396来调节第二传动部3941位于第二板柄393与第一调节件381之间的长度。可以理解的,张紧第二调节件396通过调节第二传动部3941用于连接第二板柄393与第一调节件381的长度,进而调节第二传动部3941的张紧程度,进而可以调节第二板柄393驱动定位机构38的难易程度。另一方面,有利于第二传动部3941的使用寿命的延长。在本实施例中,张紧第二调节件396设置在第二板柄393侧。在其他可替换实施例中,可以设置在第一调节件381侧。张紧第二调节件396设置在第一板柄391上,包括设置有两个通孔3962主体件3961和设置在两个通孔3962之间的可拆卸的紧固件3963。第二传动部3941从一个通孔3962中穿入,从另一个通孔3962穿出主体件3961。紧固件3963旋入主体 件3961后顶端抵压住第二传动部3941,将第二传动部3941固定在主体件3961上。当需要调节时,旋松紧固件3963,紧固件3963不再抵压第二传动部3941,即可调节第二传动部3941的张紧程度。
如图52至图56所示,本实施例公开了一种斜锯,其中与实施例三相同或相应的零部件采用与实施例三相应的附图标记或名称。为简便起见,仅描述实施例四与实施例三的区别点。本实施例的斜锯与实施例三不同的是不同的第一操作部49a和第二操作部49b的具体结构等。
在本实施例中,第一操作部49a,包括:第一板柄491,在具体操作时,操作者握持第一板柄491,并使第一板柄491在在第一位置和第二位置间运动。第一板柄491以第三直线405为转轴旋转连接在工作台的第二端的壳体上。第一板柄491整体呈偏平板状,其尺寸适合成年人单手握持。
第二操作部49b,包括:第二板柄493,设置在第一板柄491上。第二板柄493在第一板柄491上以第四直线406为轴往复摆动。第四直线406垂直于第三直线405。具体的,第四直线406沿上下方向延伸。在具体操作时,操作者握持第一板柄491并用拇指拨动第二板柄493在第三和第四位置间运动。可以理解的,当操作者握持第一板柄491时,第二板柄493在第一板柄491上同时被操作者握持在手中。所以,第一板柄491被操作在第一位置和第二位置间切换时,第二板柄493由于在第一板柄491上,所以也会与第一板柄491共同在运动。也可以理解为,第一板柄491运动时必然会带动第二板柄493一同运动。第二板柄493可以相对于第一板柄491运动,即第二板柄493以第四直线406为轴运动,以使第二板柄493相对于第一板柄491在第三位置与第四位置间切换。
第一板柄491中部形成第三容纳空间491a,第二传动部3941穿入第三容纳空间491a中。第一板柄491设置有一个滑槽4913,通过滑槽4913将第三容纳空间491a与外界连通。在本实施例中,第二板柄493与第二传动部3941之间设置有第三传动部4942,第三传动部4942至少部分设置在第三容纳空间491a内。第三传动部4942的通过滑槽4913形成或连接于第二板柄493,第二传动部3941连接在第三传动部4942上。其中,第三传动部4942通过旋转轴4943连接在第一板柄491上,第三传动部4942以第四直线406为轴转动。第二传动部3941连接在第三传动部4942的偏心部分4944上。第二传动部3941进入第三容纳空间491a部分被第三固定结构4945连接在第一板柄491上。第三固定结构4945将第二传动部3941以第四直线406为圆心线设置成圆弧形。圆弧形的一端连接在第三传动部4942上,另一端伸出第三容纳空间491a。滑槽4913的为圆弧形,滑槽4913上依次设置有第三位置、第四位置和第五位置。在本实施例中,限位组件495为一个台阶限位面。从第三位置到第四位置之间的第一板柄491,其在 第三容纳空间491a内设置凸起部4951,凸起部4951在第三传动部4942和第一板柄491之间。在第四位置至第五位置时,凸起部4951结束,所以此部分与凸起部4951形成了一个凹槽4952。第二板柄493运动超过第四位置向第五位置时,第三传动部4942进入凹槽4952,即被限位在凹槽4952中,无法复位至第四位置。需要操作者按压第二板柄493使第三传动部4942脱离凹槽4952后继续向第四位置拨动第二板柄493,使第二板柄493复位至第四位置。在本实施例中,张紧调节部496设置在第三传动部4942上。其具体结构与实施例三相同。
如图57至图58所示,本实施例公开了一种斜锯,其中与实施例四相同或相应的零部件采用与实施例四相应的附图标记或名称。为简便起见,仅描述实施例五与实施例四的区别点。本实施例的斜锯与实施例四不同的第一板柄591与第二操作部59b的具体结构等。

限位组件包括第一限位部6951和第二限位部6952。其中,第一限位部6951为设置在第二板柄693上底部的槽,第二限位部6952为设置第一板柄691上侧臂的卡扣。
如图62至图63所示,本实施例公开了一种斜锯,其中与实施例三相同或相应的零部件采用与实施例三相应的附图标记或名称。为简便起见,仅描述实施例其与实施例三的区别点。本实施例的斜锯与实施例三不同的第一操作部79a与第二操作部79b的具体结构等。
在本实施例中,第一操作部79a包括第一板柄791、第一限位结构7912和第一连接部792。其中,第一连接部792设置在第一板柄791和第一限位结构7912之间,第一连接部792可以为单独的部件,连接在第一板柄791和第一限位结构7912之间。在其他可替换实施例中,第一连接部792与第一板柄791或第一连接部792与第一限位结构7912形成一个部件后进行连接。
第一板柄791以第三直线705为轴旋转。在本实施例中,第三直线705与第一轴线垂直或相交。
第二操作部79b包括第二套筒794和第一拨杆795。第二套筒794套设在第一连接部792外侧,第二套筒794以第四直线706为转轴旋转,且第一板柄791以第四直线706基本对称设置。在本实施例中,第四直线706垂直于第三直线705,第四直线706平行于第一轴线。可以理解的,当操作者握持第一板柄791时,拇指或拇指和食指可以对第二套筒794进行旋拨操作。
