具体实施方式
本发明公开了一种斜断锯, 现以具体实施例进行说明。
如图 1 和 2所示, 斜断锯 200 包括基座 1、 用来支撑被切割工件 (未图 示) 的工作台 3、 配接在工作台 3上的第一支撑件 5、 与第一支撑件 5配接的 第二支撑件 7、 及与第二支撑件 7配接的锯机构 9。 其中锯机构 9通过第一枢 转轴 11可枢转的连接在第二支撑件 7上, 这样锯机构 9就可以相对于基座 1 上、 下枢转来竖直切割工件。 在本发明的描述中, 除非另外指出, 如左、 右、 前、 后、 上和下等的方向术语, 都是正常使用该斜断锯所定义的相对方向, 如定义靠近操作者的方向为斜断锯的前侧, 远离操作者的方向为斜断锯的后 侧。
第一支撑件 5可相对于工作台 3在顺时针和逆时针两个方向转动来倾斜
一定角度, 从而对工件进行倾斜切割, 另外在第一支撑件 5和工作台 3之间 设有将第一支撑件 5锁紧在工作台 3上的倾斜锁紧机构 15 ,倾斜锁紧机构 15 可把第一支撑件 5锁紧于不同的倾斜位置, 从而对工件进行不同倾斜角度的 切割。
第一支撑件 5和第二支撑件 7均可由钢铁制成, 如此可以增加刚性, 当 然也可以釆用铝合金等轻质材料, 如此还可减轻整机重量。
基座 1具有在水平方向上支撑工件的基座支撑面 19。 在基座 1上设有护 栏 21 , 该护栏 21具有与基座支撑面 19垂直设置的竖直抵靠面 23 , 竖直抵靠 面 23用于在竖直方向上抵靠工件, 对工件进行定位, 方便进行切割操作。
工作台 3 同样具有用于在水平方向上支撑工件的工作台支撑面 25 , 该工 作台支撑面 25基本与基座支撑面 19相平齐,工作台支撑面 25与基座支撑面 19相配合用于共同支撑工件。 工作台 3上设有纵长方向延伸的切割槽 27。
锯机构 9 包括马达 29、 由马达 29驱动的圆锯片 31、 定护罩 33和活动护 罩 35 , 其中圆锯片 31绕着其旋转轴线 37旋转, 从而切割工件; 在锯机构 9 上还设有操作手柄 39和搬运把手 41 , 操作手柄 39用于操作者握持锯机构 9 进行切割工作, 在操作手柄 39上还设有开关 (未图示), 用来启动和关闭马 达 29 ; 搬运把手 41用于方便操作者搬运斜断锯 200 ; 定护罩 33通常与马达 29 固定连接, 用以遮盖住部分圆锯片 31 ; 活动护罩 35铰接在定护罩 33上, 用于在斜断锯 200处于非切割位置时, 遮盖住剩余的圆锯片 31 , 而且活动护 罩 35 可以相对定护罩 33旋转, 以暴露圆锯片 3 1 用来切割工件。 活动护罩 35 连接有活动护罩驱动装置 43 , 用来快速打开和关上活动护罩 35 , 此处的 活动护罩驱动装置 43为连杆, 当然, 也可以设计成其它结构。
锯机构 9与第二支撑件 7通过第一枢转轴 1 1连接, 从而, 按压操作手柄 39就可以使锯机构 9枢转来执行切割工作。 当切割工件时, 圆锯片 3 1 至少 部分伸入切割槽 27 内。
工作台 3可旋转的设置在基座 1上, 使得该工作台 3可带动锯机构 9相 对于基座 1转动, 便于进行水平的斜向切割的调整, 也就是本领域技术人员 所称的对斜切角度进行调整。 工作台 3 的转动改变圆锯片 3 1相对于护栏 21 的角度, 但始终保持圆锯片 3 1与工作台 3相垂直。
如图 3、 4和 5所示, 斜断锯 200上还设有将工作台 3锁定在基座 1上的 斜切锁紧机构 45。 斜切锁紧机构 45设置在基座 1 与工作台 3之间, 且斜切
锁紧机构 45可在释放位置和锁紧位置之间移动,用于将工作台 3相对于基座 1释放和锁紧。 当斜切锁紧机构 45处于释放位置时, 工作台 3相对于基座 1 可自 由转动。 如图 6和 7所示, 当工作台 3相对于基座 1旋转到一定位置时, 操作斜切锁紧机构 45使其移动到锁紧位置, 此时斜切锁紧机构 45使得工作 台 3不能相对于基座 1转动, 然后就可操作锯机构 9对工件进行切割。
参照图 3至图 5 ,斜切锁紧机构 45 包括用于释放或锁紧基座 3的夹具 47 和用于操作夹具的致动机构 49 , 夹具 47设置于工作台 3上, 致动机构 49可 被操作地使夹具 47将工作台 3相对于基座 1释放,从而使工作台 3可相对于 基座 1 自 由转动, 调节工作台 3相对于基座 1 的角度, 当调节到所需要角度 时, 操作致动机构 49 , 使夹具 47锁紧基座 1 , 从而把工作台 3锁紧于基座 1 上, 对工件进行斜切。
夹具 47 包括第一夹爪 50和第二夹爪 5 1。 第一夹爪 50上设置有第一夹 持面 52 , 第二夹爪 51上设置有第二夹持面 53 , 其中第二夹持面 53与第一夹 持面 52相面对设置, 且第一夹持面 52 和第二夹持面 53 定义了可与基座 1 配接的第一钳口 55。 致动机构 49可被操作地使第一夹持面 52和第二夹持面 53作相对移动, 从而使第一钳口 55变大或变小, 用于释放或锁紧基座 1。
本优选实施例中, 第一夹爪 50和第二夹爪 5 1通过转轴 57旋转连接。 当 然, 第一夹爪 50和第二夹爪 51也可以釆用其他的连接的方式, 如第二夹爪 51 相对于第一夹爪 50可滑移地设置, 只要第一夹持面 52和第二夹持面 53 能作相对移动, 使第一夹持面 52和第二夹持面 53之间的距离变大或缩小, 从而使第一夹持面 52和第二夹持面 53所定义的第一钳口 55将工作台 3相对 于基座 1释放或锁紧。
第一夹爪 50 相对于第二夹爪 5 1 旋转的转轴 57 的轴线相对于工作台 3 的位置恒定。 从而使得斜切锁紧机构 45稳定, 而且结构简单。
本优选实施例中, 转轴 57设置于工作台 3上, 使得该斜切锁紧机构 45 结构简单。
用户操作致动机构 49 , 驱使夹具 47将工作台 3锁紧于基座 1 上时, 致 动机构 49在夹具 47上的施力点至转轴 57的距离大于夹具 47在基座 1上的 施力点至转轴 57的距离,即致动机构 49作用于夹具 47的施力力臂大于夹具 47作用于基座 1 的施力力臂, 根据能量守恒原理, 致动机构 49作用于夹具 47 的力小于夹具 47作用于基座 1 的力, 因此该机构操作起来非常省力, 致
动机构 49只要作用于夹具 47较小的力,就可驱使夹具 47作用于基座 1较大 的力, 因此不但操作省力, 而且夹具能可靠地将工作台锁紧于基座。
夹具 47还具有与第一钳口 55相背对设置且与致动机构 49配接的第二钳 π 59。
另外, 如图 6和 7所示, 当致动机构 49驱使第二钳口 59变大时, 第一 钳口 55相应地变小以锁紧基座 1 , 从而将工作台 3可靠地锁紧于基座 1上。 如图 4和图 5所示, 第二钳口 59变小时, 第一钳口 55相应地变大以释放基 座。 使工作台 3相对于基座 1 可自 由转动, 从而调节工作台 3相对于基座 1 的位置, 对工件进行不同角度的斜切。
本优选实施例中, 致动机构 49 包括通过第一枢轴 6 1枢转设置于工作台 3上的操作件 63 , 及通过第二枢轴 65枢转设置于操作件 63的推进件 67。 第 一枢轴 61 与第二枢轴 65 间隔一段距离设置。推进件 67位于第二钳口 59中。 当操作件 63被操作地促动推进件 67枢转。 操作件 63相对于推进件 67的枢 转使推进件 67在切割槽 27的纵长延伸方向上产生一定的位移量, 上述位移 量足以使夹具 47释放或锁紧基座 1。
推进件 67在切割槽 27的纵长延伸方向上远离夹具 47产生的位移量,用 于使夹具 47释放基座 1。 相应地, 推进件 67在切割槽 27的纵长延伸方向上 靠近夹具 47产生的位移量, 用于使夹具 47锁紧基座 1 。
操作件 63设置在工作台 3的前端, 这样便于使用者操作, 上述的前端为 通常定义的操作者操作的方向。
如图 3所示, 操作件 63 与工作台 3之间设置有弹性件 69 , 当斜切锁紧 机构 45处于释放位置时, 弹性件 69用于使工作台 3相对于基座 1处于可转 动状态, 这样可更方便地操作工作台 3的转动。 本优选实施例中, 弹性件 69 设置为压簧。当然,弹性件 69也可以设置为扭簧或拉簧等其它类型的弹性件。
斜切锁紧机构 45 还进一步包括可部分容纳夹具 47 的座体 73 , 座体 73 通过螺栓 75 固定设置于工作台 3上, 转轴 57也可设置于座体 73上。
座体 73具有收容部 77 , 收容部 77用于收容第一夹爪 50 , 使夹具 47更 力口 t、定。
基座 1具有与第一夹持面 52和第二夹持面 53配接的凸缘 79 ,当夹具 47 可被操作地将工作台 3锁紧于基座 1上时, 第一夹持面 52和第二夹持面 53 与凸缘 79 匹配。 这样大大增加了配接面积, 将工作台 3更可靠地锁紧于基座
1 .
本优选实施例中, 第一枢轴 61设置于工作台 3上, 工作台 3上设置有通 孔 81 , 第一枢轴 61 穿设于通孔 81 中。 第二枢轴 65可转动地设置于操作件 63上, 推进件 67设置于第二枢轴 65上。
另外, 第一枢轴 61与第二枢轴 65平行, 这样当旋转操作件 63 , 从而促 动推进件 67时, 由于增长了操作操作件 63的力臂, 使得操作起来非常省力, 更力口方便操作。
本优选实施例中, 推进件 67 固定设置于第二枢轴 65上。 当然, 推进件 67也可活动设置于第二枢轴 65上。
如图 4和 5所示, 当向上转动操作件 63时, 推进件 67被促动, 从而使 夹具释放基座 1。 具体为推进件 67沿第二枢轴 65相对于操作件 63枢转, 上 述枢转使推进件 67在切割槽 27的纵长延伸方向上远离夹具 47产生一定的位 移量, 上述位移量足以使夹具释放基座 1 , 从而使工作台 3相对于基座 1 可 自 由转动。
进一步参照图 6和 7 , 当把工作台 3转动到所需要的斜切角度时, 向下 转动操作件 63 , 此时推进件 67被促动, 从而使夹具锁紧基座 1。 具体为推进 件 67沿第二枢轴 65相对于操作件 63枢转, 该枢转使推进件 67在切割槽 27 的纵长延伸方向上靠近夹具 47 产生一定的位移量, 该位移量足以使夹具 47 锁紧基座 1 , 从而把工作台 3锁紧于基座 1上, 然后可对工件进行斜切。
如图 3所示, 操作件 63上设置有配接孔 82 , 第一枢轴 61 穿设于配接孔 82中, 推进件 67纵长延伸的方向与第二枢轴 65的轴线相垂直。
另外为使斜切锁紧机构 45操作更加省力, 转轴 57设置成与第一枢轴 61 平行。 进一步的, 转轴 57也与第二枢轴 65平行。
斜断锯上还进一步设置有斜角定位机构 83 , 斜角定位机构 83 用于实现 工作台 3 与基座 1 之间的快速定位。 斜角定位机构 83 包括枢转设置于座体 77的定位件 85 , 定位件 85与座体 77之间设置有压簧 87 , 定位件 85上设置 有与基座 1上的凹口 89配接的突起部 91 ,压簧 87用于使突起部 91 与基座 1 上的凹口 89保持配接。
进一步参照图 8 , 本优选实施例中, 斜断锯包括可操作地驱动第二支撑 件 7相对于第一支撑件 5 沿切割槽 27 的延伸方向移动的驱动机构 93。 该驱 动机构 93 包括活动配接于第一支撑件 7和第二支撑件 5上的主驱动件 95。
操作者可直接操作主驱动件 95 , 从而使第二支撑件 7相对于第一支撑件 5沿 切割槽 27的延伸方向移动, 以进行不同规格工件的切割。 本发明的斜断锯具 有较高的切割能力, 且操作方便。
驱动机构 93还包括从动件 97 , 主驱动件 95枢转设置于第一支撑件 5和 第二支撑件 7 之一上, 从动件 97 枢转连接于第一支撑件 5 和第二支撑件 7 另一个上, 且从动件 97活动连接于主驱动件 95上。 如此设置, 第二支撑件
7相对于第一支撑件 5的移动更稳定可靠。
在本实施例中, 主驱动件 95通过销轴 98枢转设置于第一支撑件 5上, 从动件 97的通过销轴 99枢转连接于第二支撑件 7上,且主驱动件 95还通过 销轴 101与从动件 97枢转连接。
当然, 该主驱动件 95与从动件 97还可以通过其它的活动连接方式, 如 销和滑槽的配合等。
当要移动第二支撑件 7 时, 扳动主驱动件 95 , 主驱动件 95相对于第一 支撑件 5枢转, 进而通过从动件 97带动第二支撑件 7移动, 从而使第二支撑 件在切割槽 27的延伸方向上移动一定距离, 以切割不同规格的工件。 因此, 该斜断锯非常方便调节。
为了使该驱动机构 93更加稳定、可靠的驱动第二支撑件 7相对于第一支 撑件 5移动,该驱动机构 93在设置主驱动件 95和从动件 97的另一侧还设有 第一连接件 103和第二连接件 105。
其中第一连接件 103的第一端枢转连接于第一支撑件 5上, 第二连接件 105 的第一端枢转连接于第二支撑件 7上, 且第一连接件 103 的第二端与第 二连接件 105的第二端活动连接。
在本实施例中,第一连接件 103和第二连接件 105与主驱动件 95和从动 件 97分别对称设置于第二支撑件 7的两个相背离的侧面上。 如此, 第二支撑 件 7相对于第一支撑件 5的移动更平稳。 当然, 第一连接件 103和第二连接 件 105与主驱动件 95和从动件 97也可以不对称设置。
在本实施例中,第一连接件 103的第一端与主驱动件 95 同轴枢转连接于 第一支撑件 5 上。 在本实施例中, 第一连接件 103 的第一端与主驱动件 95 的第一端通过销轴 98枢转连接于第一支撑件 5上。
第二连接件 105的第一端与从动件 97的第一端同轴枢转连接于第二支撑
件 7上。
第一连接件 103的第二端与第二连接件 105的第二端通过销轴 107枢转 连接, 该销轴 107与销轴 101 同轴设置。
第二支撑件 7相对于第一支撑件 5沿切割槽 27的延伸方向可移动地设置 在第一支撑件 5上。 在本实施例中, 第二支撑件 7通过配合机构 109设置于 第一支撑件 5上, 并在到达至少两个预先确定的工作位置后进行切割工作, 而在移动过程中无法进行工作。
预先确定的工作位置与可容许的最大切割工件规格相对应。 可容许的工 件的最大切割规格包括可容许的工件在纵轴 13方向上的最大尺寸,也就是工 件的宽度、 或是在垂直于纵轴 13方向上的最大尺寸, 也就是工件的高度。
配合机构 109包括设置在第一支撑件 5上的沿纵轴 13方向延伸的导引块 111、 设置在第二支撑件 7上的与导引块 111配合的导引槽 113 , 当然, 导引 块 111也可以设置在第二支撑件 7上, 而与其相配合的导引槽 113设置在第 一支撑件 5上。
如此, 通过导引块 111相对于导引槽 113之间的滑动磨擦配合, 第二支 撑件 7相对于第一支撑件 5可沿着纵轴 13的方向前、 后移动, 且纵轴 13垂 直于第一枢转轴 11。
而导引块 111和第一支撑件 5可以一体成形; 导引槽 113和第二支撑件 7 也可以一体成形。 如此, 该斜断锯无需借助于其它媒介就可以实现第二支 撑件 7相对于第一支撑件 5的滑动, 所以使得该斜断锯的结构紧凑、 成本较 低。
而且由于该斜断锯只有在预先确定的几个工作位置之间进行滑动, 所以 不会经常滑动, 如此也会减少导引块 111和导引槽 113之间的磨损。 当然, 为了减少磨损, 也可以在导引槽 113和导引块 111之间设置磨擦垫。
在本优选实施例中, 导引槽 113为燕尾槽, 当然, 导引槽 105还可以是 T型槽、 V型槽等其它形式的配合槽。 而导引块 111设置成与导引槽 113相 匹配的形状。
第二支撑件 7相对于第一支撑件 5仅在至少两个预定工作位置进行切割 工作。 斜断锯 200还包括支撑件锁紧机构 115。 支撑件锁紧机构 115 用于提 供第二支撑件 7相对于第一支撑件 5在预定的工作位置的锁紧固定, 也就是 用于将第二支撑件 7与第一支撑件 5的相对位置固定, 从而实现稳定切割。
支撑件锁紧机构 115 包括设置于第一支撑件 5或者第二支撑件 7上的配 合件 117以及设置于主驱动件 95上与配合件 117配合的锁紧件 119。 如此, 用户操作主驱动件 95 既可使第二支撑件 7相对于第一支撑件移动,也可把第 二支撑件 7锁定于预定的工作位置, 从而实现单手操作, 非常方便用户使用。
为了与斜断锯的预定的工作位置相匹配, 配合件 117为至少两个间隔设 置的凹槽。 在本实施例中, 配合件 117是三个间隔设置的凹槽。 当然, 根据 使用的需要, 凹槽的个数可以是 2个, 4个或者更多。
主驱动件 95通过销轴 98枢转连接于第一支撑件 5或者第二支撑件 7上, 凹槽围绕销轴 98周向间隔设置。
主驱动件 95上沿主驱动件 95的纵长延伸方向延伸设置有与锁紧件 119 配接的长孔 121。
锁紧件 119上设置有供操作者操作的操作把手 123。 操作把手 123可以 方便操作者控制锁紧件 119的位置。 在不同的支撑件锁紧机构实施方式中, 操作把手控制锁紧件 119位置的结构形式也不同。
支撑件锁紧机构 115还包括促使锁紧件 119始终与配合件保持配合的弹 性件 125。 由于设置了弹性件 125 , 可以使支撑件锁紧机构 115在锁紧件 119 到达与配合件 117配合的位置后,保持锁紧件 119与配合件 117的配合状态, 操作者不需施加额外的保持力, 操作方便, 舒适。 在本实施例中, 弹性件 125 为压簧。 当然, 本领域技术人员容易知道, 弹性件 125还可以釆用其它结构 形式, 比如拉簧, 扭簧或者其它能够对锁紧件 119产生偏压抵靠力的弹性结 构。
支撑件锁紧机构 115还包括固定设置于主驱动件 95上的盖体 127。 弹性 件 125设置于锁紧件 119与盖体 127之间。盖体 127相对于主驱动件 95 固定 设置, 止挡弹性件 125从主驱动件 95上脱出。
在本实施例中, 操作把手 123上设置有用于收容弹性件 125的收容腔。 弹性件 125位于盖体 127与操作把手 123之间。 这样, 可以充分利用操作把 手 123与盖体 127之间的空间, 既可以实现操作把手 123对锁紧件 119位置 的控制, 又可以以最紧凑的结构放置弹性件 125。 达到了各种功能结构的最 佳配合。
在具体的实施方式中, 斜断锯具有三个预先确定的工作位置。 相应的,
在第二支撑件 7上设有与预先确定的三个工作位置相对应配合件, 即第一、 第二、 第三收容槽 129、 131、 133。 在主驱动件 111 上设置有与上述收容槽 129、 131、 133相配合的锁紧件 119。 本实施例中, 锁紧件是销钉。 当然, 本 领域技术人员也可以将锁紧件 119设置为其它结构形式, 比如螺钉或者凸轮 等。 在本实施例中, 锁紧件 119可滑移地设置于主驱动件 95上。 优选的, 锁 紧件沿着垂直于销轴 98 的方向移动, 也就是说, 主驱动件 95上的长孔 121 的延伸方向垂直于销轴 98。
进一步参照图 9和 10 , 在本实施例中, 弹性件 125为压簧。 支撑件锁紧 机构 115还包括通过螺栓 129 固定设置于主驱动件 111 上的盖体 127 , 弹性 件 125设置于锁紧件 119与盖体 127之间。 由于受弹性件 125的压迫, 在没 有外力作用的情况下, 锁紧件 119始终保持与第一、 第二、 第三收容槽 129、 131、 133 中的一个配合。 这样在工作位置时, 锁紧件 119与相应收容槽配合, 可以实现对第二支撑件 7的可靠锁紧。
主驱动件 95上设置有与锁紧件 119配接的长孔 121 , 长孔 121 沿驱动件 111 的纵长延伸方向延伸。 操作把手 123套设于主驱动件 95的一端。 本实施 例中, 锁紧件 119是圆柱形销钉, 穿设于操作把手 123上。 锁紧件 119相对 于操作把手 123 不可线性移动, 但是可以沿长孔 121 线性移动。 锁紧件 111 的轴线垂直于主驱动件 95的纵长延伸方向。操作把手 123 内设置有用于收容 弹性件 125 的收容腔 134。 盖体 127位于操作把手 123远离锁紧件 119 的一 端。操作把手 123 内具有用于抵靠弹性件的抵靠面。弹性件 125位于盖体 127 和操作把手 123之间。 本实施例中, 弹性件 125 —端抵靠于盖体 127 , 另一 端抵靠于操作把手 123的抵靠面上。
在弹性件 125的弹力作用下, 操作把手 123远离盖体 127 , 操作把手 123 带动锁紧件 119与第二支撑件 7上的相应收容槽配接, 从而第二支撑件 7被 可靠锁紧。
进一步参照图 11 , 操作操作把手 123 , 使操作把手 123克服弹性件 125 的弹力, 向靠近盖体 127的方向移动, 操作把手 123带动锁紧件 119与第二 支撑件 7上的相应收容槽脱开, 从而第二支撑件 7被释放, 第二支撑件 7相 对于第一支撑件 5可移动。
当锁紧件 119与第二支撑件 7上的相应收容槽脱开, 第二支撑件 7被释 放时, 扳动操作把手 123 , 带动主驱动件 95运动, 第一连接件 113被联动,
从而带动第二支撑件 7相对于第一支撑件 5移动。当移动到预定工作位置时, 释放操作把手 123 , 在弹性件 125 的弹力作用下, 操作把手 123 带动锁紧件 119 自动与第二支撑件 7上的相应收容槽配接, 从而第二支撑件 7被可靠锁 紧。
本优选实施例中, 斜断锯 200设置有三个工作位置。 进一步参照图 12 , 锁紧件 119与第一收容槽 129配接, 把第二支撑件 7锁紧在第一工作位置。
如图 13所示, 锁紧件 119与第二收容槽 131 配接, 把第二支撑件 7锁紧 在第二工作位置。
如图 14所示, 锁紧件 119与第三收容槽 133配接, 把第二支撑件 7锁紧 在第三工作位置。
该斜断锯 200还包括用于指示预先确定的工作位置的指示机构 139。 指 示机构 139 包括设置在第一支撑件 5上的工作位置标记 141和设置在第二支 撑件 7上的指示标记 143。 当第二支撑件 7运动到相应工作位置时, 指示标 记 143与工作位置标记 141正对。 当然, 工作位置标记也可以设置在第二支 撑件 5上, 而与其相配合的指示标记设置在第一支撑件 4上。 与预定的工作 位置数量相对应, 如图 12至 15所示, 工作位置标记 139 包括第一、 第二、 第三工作位置标记 145、 147、 149。 当然, 工作位置标记 139 最好是使用最 大切割工件的规格做标记, 方便操作者使用。
另外为更方便操作者观察, 工作位置标记 139设置于靠近第一、 第二、 第三收容槽 129、 131、 133的位置, 相应地, 第一、 第二、 第三工作位置标 记 141、 143、 145与第一、 第二、 第三收容槽 129、 131、 133相对应设置, 用于指示斜断锯的不同切割位置, 此时可不用另外设置指示标记。 当然, 工 作位置标记 139最好是使用最大切割工件的规格做标记。
如图 12所示, 在第一工作位置, 这时斜断锯 200的最大切割工件规格是 最大宽度是 6英寸的工件 400最高可切 2英寸; 或是最大高度是 4英寸的工 件 400最高可切 4英寸。 也就是说在这一位置, 只要小于该最大切割工件规 格的工件, 即在平行于纵轴方向上小于等于 6英寸, 以及在垂直于纵轴方向 上小于等于 2英寸, 则该斜断锯都可以完成。
如图 13所示, 在第二工作位置, 这时斜断锯 200的最大切割规格是两个 最大宽度是 6英寸的, 最高可切 2英寸的工件 400。 也就是说在这一位置, 只要小于该最大切割工件规格的工件, 该斜断锯都可以完成。 另外, 也可同
时切割几个工件, 只需确保几个工件叠加后的尺寸仍在斜断锯的最大切割范 围内即可。
如图 14所示, 在第三工作位置, 这时斜断锯 200的最大切割规格是最大 宽度是 8英寸的工件 400最高可切 2英寸。 也就是说在这一位置, 只要小于 该最大切割工件规格的工件, 该斜断锯都可以完成。
本发明的构思同样适合于第一支撑件 5和第二支撑件 7之间的配合表面 并不是平行于纵轴 13方向,也就是说第二支撑件 7相对于第一支撑件 5移动 方向并不需要总是沿着纵轴 13方向。 如此, 有利于提高斜断锯的切割能力。 而且该配合表面还可以不是平面, 可以是曲面等其它形状的表面。
这时, 若干预先确定的工作位置在纵轴 13方向上的投影依次排列。 也就 是说, 虽然第二支撑件相对于第一支撑件实际的运动方向不一定是平行于纵 轴方向, 但该实际运动方向在平行于纵轴方向上有分量。
当然, 第二支撑件也可以不通过滑动的方式来实现其相对于第一支撑件 前、 后移动 0
如图 15至 17所示, 本发明的第二实施方式, 与第一实施方式相同, 斜 断锯 400 包括基座 147、 用来支撑被切割工件 (未图示) 的工作台 149、 配接 在工作台 149上的第一支撑件 151、与第一支撑件 151配接的第二支撑件 153、 及与第二支撑件 153 配接的锯机构 155。 其中锯机构 155通过枢转轴 157可 枢转的连接在第二支撑件 153上。 工作台 149上设有纵长方向延伸的切割槽 150。 斜断锯 400还包括设置于基座 147上用于抵靠工件的护栏 159。
锯机构 155 包括马达 (未图示)、 由马达驱动的锯片 163。 工作台 149可 旋转的设置在基座 147上, 使得该工作台 149可带动锯机构 155相对于基座 147 转动, 便于进行水平的斜向切割的调整, 也就是本领域技术人员所称的 对斜切角度进行调整。 工作台 149的转动改变圆锯片 163相对于护栏 159的 角度, 但始终保持圆锯片 163与工作台 149相垂直。
斜断锯还包括可操作地驱动第二支撑件 153相对于第一支撑件 151 沿切 割槽 150 的延伸方向移动的驱动机构 165。 该驱动机构 165 包括配接于第一 支撑件 7和第二支撑件 5上的主驱动件 167。
第二实施方式与第一实施方式所不同的是, 主驱动件 167第一端枢转连 接于第一支撑件 151和第二支撑件 153之一上, 主驱动件 167第二端活动连 接于第一支撑件 151和第二支撑件 153另一个上。
在本实施例中, 主驱动件 167第一端枢转连接在第一支撑件 151上, 主 驱动件 167第二端枢转连接在第二支撑件 153上。 当然, 主驱动件 167第二 端也可以通过其它活动连接方式连接在第二支撑件 153上, 如通过销和槽的 配合等。
驱动机构 165还包括从动件 169 , 从动件 169 的两端均枢转连接于第一 支撑件 151和第二支撑件 153上。 在本实施例中, 从动件 169分别通过销轴 170和 172枢转设置在第一支撑件 151和第二支撑件 153上。
主驱动件 167和从动件 169平行设置。第一支撑件 151和第二支撑件 153 并不直接接触, 且第一支撑件 151和第二支撑件 153与主驱动件 167和从动 件 169形成平行四连杆机构。
在本实施例中, 主驱动件 167设置于从动件 169和锯片 163之间。 如此 主驱动件 167更靠近操作者方便操作。
在主驱动件 167上设置有供用户操作的操作部 171。用户操作操作部 171 , 因第一支撑件 151和第二支撑件 153与主驱动件 167和从动件 169形成了平 行四连杆机构, 从而使得主驱动件 167和从动件 169带动第二支撑件 153相 对于第一支撑件 151平动。 操作者可以根据不同规格的工件需要, 在不同的 切割位置切割工件, 因此该斜断锯非常方便操作。 当然,操作部 171也可以设 置在从动件 169上。
从动件 169为塑料件, 这样可减轻斜断锯的整机重量, 且可降低制造成 本。
第二支撑件 153具有位于锯片 163相对两侧的第一侧部 173和第二侧部 175。 优选的, 从动件 169设置于第一侧部 173和第二侧部 175之间。 且从动 件 169与锯片 163所在的平面相交。 如此, 可大大提高第二支撑件 153相对 于第一支撑件 151 的稳定性。
进一步参照图 18 , 从动件 169上设置有枢转孔 177 , 为了增加强度, 提 高第二支撑件 153相对于第一支撑件 151的稳定性,从动件 169沿枢转孔 177 的轴线延伸一定厚度, 优选的, 该厚度足以使从动件 169 贴合第一侧部 173 和第二侧部 175 , 如此设置可更进一步提高第二支撑件 153的稳定性。
在从动件 169上朝向圆锯片 163 的一侧设置有若干个孔 179 , 更进一步 降低了斜断锯的重量及制造成本。 优选的, 孔 179设置为三角形, 三角形设 置可提高从动件 169的刚度和强度, 进而提高第二支撑件 153的稳定性。
进一步参照图 19至图 21 , 当操作操作部 171 , 使主驱动件 167和从动件 169分别围绕各自的销轴的轴线方向旋转, 从而带动第二支撑机构 153相对 于第一支撑件 151 沿着切割槽 150的延伸方向移动到不同的工作位置。
本实施例中, 为提供第二支撑件 153相对于第一支撑件 151在相应的工 作位置的锁紧, 从而使斜断锯可在不同的工作位置切割不同规格的工件。 设 置有与第一实施方式相同的支撑件锁紧机构, 且相应地设置有三个预先确定 的工作位置, 在此不再做详细赘述。
为使第二支撑件 153 在移动过程中或处于锁紧状态的切割位置时更稳 定, 再参见图 18 , 驱动机构 155还进一步包括枢转连接于第一支撑件 151和 第二支撑件 153上的第一连杆 189 , 第一连杆 189与主驱动件 167分别设置 于第一侧部 173和第二侧部 175 两个相背离的侧面上。
本优选实施例中, 第一连 4干 189一端与主驱动件 167通过枢轴 191 同轴 枢转设置于第一支撑件 151上, 且第一连杆 189另一端与主驱动件 167通过 枢轴 193 同轴枢转设置于第二支撑件 153上。 如此设置, 方便装配, 而且可 降低制造成本。
驱动机构 155还包括第二连杆 191 , 第二连杆 191 与主驱动件 167设置 于第二支撑件 153的同侧。第二连杆 191的一端与主驱动件 167通过枢轴 191 同轴枢转设置于第一支撑件 151 上; 第二连杆 191 的另一端与主驱动件 167 通过枢轴 193 同轴枢转设置于第二支撑件 153上。 本优选实施例中, 第二连 杆 191设置于主驱动件 167与第二支撑件 153之间。
螺母 195与枢轴 191、 193配合, 从而固定主驱动件 167、 第一连杆 189 及第二连杆 191。
上述的实施例仅仅是为了让本领域技术人员理解本发明而提供的最优选 的实施方式。 本发明并不仅限于上述具体的实施例。 任何本领域技术人员所 易于思及的改进均在本发明的发明构思之内。
