Description
台式工具 技术领域
本发明涉及一种台式工具, 尤其是一种斜断锯。
背景技术
台式工具是一种利用电机驱动锯片旋转, 从而用于锯切工件的机械, 其 一般包括斜断锯、 台锯等等。 传统的斜断锯包括用来放置工件的底座、 配接 在底座上的支撑架、 配接在支撑架上的锯机构, 其中支撑架带动锯机构可以 相对于垂直位置做倾斜切割, 而由于传统的斜断锯中马达水平设置, 这样支 撑架只能相对于垂直位置向一侧倾斜运动, 否则会使得马达壳体与护栏或底 座产生干涉, 所以传统的斜断锯一般只能向左倾斜来切割工件, 其最大的倾 斜角在 45度左右。 而这种斜断锯由于只能实现单向左侧倾斜切割, 所以在需 要向右侧倾斜切割时, 只能将工件翻转过来, 利用左侧摆动来实现, 使用起 来非常不方便, 从而大大限制了斜断锯的使用范围, 无法满足不同使用者的 要求。 在实际操作过程中, 也增加了操作者的劳动强度, 同时降低了工作效 率。
对此, 业界技术人员做了相应的改进, 如美国专利申请 US 2006/01 01 967 号揭示了一种斜断锯, 该斜断锯包括工作台、枢转连接在工作台上的锯机构, 其中锯机构包括马达和由马达旋转驱动的锯片, 且马达竖直设置在锯片 的右 侧, 以减少马达壳体与护栏或底座产生干涉, 从而实现双摆切割。 而马达设 置在锯片 的右侧, 会遮盖住锯片右侧的部分工件, 从而影响了操作者的观察 视野; 而由于锯机构中的马达重量最大, 所以整个锯机构的重心靠近马达, 而该斜断锯中马达靠近锯片轴设置, 如此就使得锯机构的重心靠前, 也就是 说锯机构的重心与锯机构的枢转轴之间的垂直距离较远, 这样力臂增加, 影 响了锯机构的复位。

具体实施方式
下面就以最佳实施例, 来说明本发明的创作构思。
台式工具一般包括了斜断锯、 滑动斜断锯、 台锯等等, 下面结合台式工 具中的典型产品, 斜断锯来阐述本发明的创作构思及优点。
通常斜断锯有一个工作位置, 如图 1 所示; 相应地, 斜断锯还有一个休 止位置, 如图 2所示。 斜断锯包括底座 1、 枢转配接在底座 1 上的工作台 2、 枢转配接在工作台 2上的支撑架 4、枢转配接在支撑架 4上的锯机构 3, 其中 支撑架 4通过枢轴 41 可枢转的设置在工作台 2上, 锯机构 3通过枢转轴 30 可枢转的设置在支撑架 4上,从而使得锯机 3 能绕着枢转轴 30在工作位置和 休止位置之间枢转。枢转轴 30作为锯机构 3的枢转轴,其上还套设有扭簧(未 图示), 这样操作者下压锯机构 3使其枢转, 则压縮扭簧切割工件, 而当切割 好工件后, 锯机构 3在扭簧的作用下快速复位。 在描述中, 除非另外指出, 方向术语, 如左、 右、 前、 后、 上和下等, 都是相对于正常使用该斜断锯的 方向。
底座 1 具有靠近操作者操作的前侧、 与前侧相对设置的后侧, 且该底座 1 上对称设有护栏 1 1, 该护栏 1 1 主要用于在竖直方向上抵靠工件, 便于切割 工件。 工作台 2可旋转的设置在底座 1 上, 在工作台 2和底座 1 之间设有将 工作台 2锁紧在底座 1 上的锁紧机构 20。 工作台 20 具有水平方向上支撑工 件的支撑平面 21。
支撑架 4通过枢轴 41 可枢转的连接在工作台 2上, 从而使得该支撑架 4 可带动锯組件 3围绕该枢轴 41相对于工作台 2在顺时针和逆时针两个方向转 动来倾斜一定角度切割工件, 也就是说锯組件 3可相对于工作台 2 向左、 右 两侧倾斜来实现双摆切割,操作者可以根据需要自行调整该锯組件 3的角度, 进而以不同的角度倾斜切割工件。
锯机构 3包括锯片 31、 驱动锯片 3 1 旋转的马达 33、 固定护罩 34和活动 护罩 35, 其中马达 33 可旋转设置在马达壳体 32 中, 固定护罩 34与马达壳 体 32 固连, 用以遮盖住部分锯片 31, 且固定护罩 34还设有收容马达壳体 32 的收容腔 341 ; 活动护罩 35铰接在固定护罩 34上, 用来在非切割位置, 遮 盖住剩余的锯片 31, 而且活动护罩 35 可以相对固定护罩 34旋转, 以暴露锯
片 31 用来切割工件, 活动护罩 35连接有活动护罩驱动装置 (未图示), 用来 快速打开和关上活动护罩。 在锯机构 3上还设有手柄 36, 该手柄 36 用于操 作者握持锯机构 3进行工作, 在手柄 36上设有开关 (未图示), 用来启动和 关闭马达 33。 固定护罩 34通过枢转轴 30与支撑架 4旋转连接, 从而, 操作 手柄 36就可以使锯机构 3上、 下枢转来切割工作。
如图 3 所示, 锯片 31 具有锯片平面且配接在锯片轴 31 1 上, 由于锯片 31 有一定的厚度, 因此把锯片 31 理想化认为其厚度极小时, 锯片 31 所在的 平面即是锯片平面,锯片轴 31 1 具有锯片轴轴线 31 2;马达 33前后方向设置, 且马达壳体 32 与锯片平面相交, 由马达 33驱动的马达轴 331 具有马达轴轴 线 332。 斜断锯还界定了一个穿过锯片轴 31 1 且与支撑平面 21 平行的中间平 面 (未图示), 参见图 1 所示, 斜断锯处于工作位置, 马达 33相对于中间平 面向上倾斜设置, 当然, 该马达 33 也可以相对于底座 1 垂直设置。 如图 2 所示, 斜断锯处于休止位置, 马达 33相对于中间平面向下倾斜设置。
再参见图 3所示, 锯机构 3还包括设置在锯片轴 31 1 和马达轴 331 之间 传动机构 5, 马达 33 通过该传动机构 5 来驱动锯片 31 旋转。 该传动机构 5 包括第一级减速机构 51、 第二级减速机构 52 以及用于连接该第一、 第二级 减速机构 51、 52的中间轴 53, 其中中间轴 53具有与马达轴 331 配接的第一 端、 与锯片轴 31 1 配接的第二端, 且具有中间轴轴线 531。 该斜断锯还界定 了一个垂直于锯片平面的基准平面, 中间轴轴线 531 位于的基准平面内。 在 基准平面上, 而马达轴 31 1 和锯片 31 位于中间轴 53的同侧。 如此, 马达 32 更靠近锯片 31 使得结构比较紧凑, 为操作者提供了更好的观察视野。
在本实施例中, 第一级减速机构 51 是圓柱齿轮組, 包括设置在马达轴 331 上的第一齿轮 51 1、 与第一齿轮 51 1 啮合的第二齿轮 51 2, 其中第二齿轮 51 2设置在中间轴 53 的第一端, 且第一、 第二齿轮 51 1、 51 2是圓柱齿轮。 如此, 中间轴 53和马达轴 331 与锯片平面平行, 且马达轴 331 到锯片平面的 距离不大于中间轴 53到锯片平面的距离,也就是说马达轴轴线 332到锯片平 面的距离小于或等于中间轴轴线 531 到锯片平面的距离,在这里, 马达轴 331 和中间轴 53 到锯片平面的距离都是其实际长度中的轴线与锯片平面之间的 距离。 如此, 马达壳体 32 与锯片平面相交, 使得马达 33 与马达壳体 32更靠 近锯片 31, 从而使得结构比较紧凑。
设置在马达轴 331 上的第一齿轮 51 1 远离锯片轴 331 设置,第一齿轮 51 1 具有靠近马达 33 的第一端面和相对设置的第二端面,其中第二端面到锯片轴 31 1 的锯片轴轴线 31 2 的最小距离不小于锯片 的半径。 同时, 中间轴 53的长 度 (指的是中间轴实际长度) 不小于锯片 31 的半径, 如此使得马达壳体 32 可以远离底座 1 设置 (如图 1 和图 2所示), 增大了马达壳体 32 与底座 1 之 间的空间, 如此可以很方便地设置集尘装置, 从而提高集尘效率。 而且也使 得马达 33 向后靠近锯机构 3的枢转轴 30设置, 如此锯机构 3的重心与枢转 轴 30之间的垂直距离縮短, 这样力臂縮短, 提高了锯机构 3的复位能力。
第二级减速机构 52 是圓锥齿轮組, 包括设置在锯片轴 31 1 上的第三齿 轮 521、 与第三齿轮 521 啮合的第四齿轮 522, 其中第四齿轮 522设置在中间 轴 53 的另一端, 第三、 第四齿轮 521、 522是圓锥齿轮且是 90度圓锥齿轮, 如此中间轴 53垂直锯片轴 31 1 设置。当然,如本领域普通技术人员所熟知的, 可以利用圓锥齿轮的锥度来改变中间轴 53 与锯片轴 31 1 之间的夹角。
当然, 该第二级减速机构 52也可以是准双曲面齿轮組, 也就是说第三、 第四齿轮 521、 522是准双曲面齿轮。 由于利用准双曲面齿轮作为传动机构, 使得在进行切割工作时可以很好的减小噪音, 而且传动平稳, 可以提高切割 精度。
再参见图 3, 设置在马达轴 331 上的第一齿轮 51 1 和设置在锯片轴 331 上的第三齿轮 521 在基准平面的投影位于中间轴轴线 531 的同一侧, 且位于 中间轴轴线 531 靠近锯片平面的同一侧。 如此使得马达轴 331 到锯片平面的 距离小于或等于中间轴 53到锯片平面的距离, 马达壳体 32可以与锯片平面 相交, 从而使得马达 33与马达壳体 32更靠近锯片 31, 这样, 可以减少马达 壳体 32和固定护罩 34在左、 右方向上的整体宽度, 防止了马达壳体 32与护 栏 1 1 或底座 1 产生干涉。 从而锯机构 3可以实现左、 右 45度双侧摆动, 甚 至摆动范围可以到达 50度左右。 而且马达 33 与马达壳体 32更靠近锯片 31 可以使得结构比较紧凑, 如此为操作者提供了更好的观察视野。
如图 4至图 5所示, 本发明中第一级减速机构 51 也可以是圓锥齿轮組, 其同样可以实现本发明的发明 目的。 该第一级减速机构 51 中安装在马达轴 331 上第一齿轮 51 1、与第一齿轮 51 1 啮合的第二齿轮 51 2是圓锥齿轮。如此, 利用圓锥齿轮的锥度可以改变中间轴 53 和马达轴 331 相对于锯片平面的夹 角。
如图 4所示, 中间轴 53 相对于锯片平面倾斜设置, 而马达轴 331 平行 于锯片平面, 也就是中间轴 53与马达轴 331 具有一定的夹角, 而该夹角是锐 角。 同样该马达轴 331 靠近锯片设置, 其与锯片平面之间的距离不大于中间 轴 53到锯片平面的最小距离, 在这里, 马达轴 331 和中间轴 53到锯片平面 的距离都是其实际长度中的轴线与锯片平面之间的距离。
而第二级减速机构 52是圓锥齿轮組, 其中第三、 第四齿轮 521、 522并 不是 90度圓锥齿轮, 中间轴 53 与锯片轴 31 1 并非垂直设置。
如图 5所示, 中间轴 53相对于锯片平面平行设置, 而马达轴 331 相对于 锯片平面倾斜设置, 也就是中间轴 53与马达轴 331 具有一定的夹角, 而该夹 角是锐角。 同样该马达轴 331 靠近锯片设置, 其与锯片平面之间的最小距离 不大于中间轴 53到锯片平面的距离, 在这里, 马达轴 331 和中间轴 53到锯 片平面的距离都是其实际长度中的轴线与锯片平面之间的距离。
而第二级减速机构 52是圓锥齿轮組, 其中第三、 第四齿轮 521、 522是 90度圓锥齿轮, 中间轴 53 与锯片轴 31 1 垂直设置。
当然, 还可以根据传动机构 5 中不同锥度的圓锥齿轮, 使马达轴 331 与 中间轴 53平行设置, 但相对于锯片平面倾斜设置, 或是马达轴 331 与中间轴 53 不平行, 也均相对于锯片平面倾斜设置。 但是, 不管第一级减速机构 51 是圓柱齿轮级或圓锥齿轮組,第二级减速机构 52是圓锥齿轮組或准双曲面齿 轮级, 其中设置在马达轴 331 上的第一齿轮 51 1 与设置在锯片轴 331 上的第 三齿轮 521 在基准平面上的投影均位于中间轴轴线 531 的同一侧, 且为靠近 锯片平面的同一侧。 而且马达轴 331 与锯片平面之间的距离小于中间轴 53 到锯片平面之间的距离, 如此使得马达壳体与锯片平面相交, 且使马达 33 与马达壳体 32更靠近锯片 31, 减少马达壳体 32和固定护罩 34的整体宽度, 防止了马达壳体 32 与护栏 1 1 或底座 1 产生干涉。从而锯机构 3可以实现左、 右 45度双侧摆动, 甚至摆动范围可以到达 50度左右。 而且马达与马达壳体 32 更靠近锯片 31 可以使得结构比较紧凑, 如此为操作者提供了更好的观察 视野。
再参见图 3、 图 4和图 5所示, 工作时, 通过开关启动马达 33, 马达 33 带动设置在马达轴 331 上的第一齿轮 51 1 旋转, 第一齿轮 51 1 啮合第二齿轮 51 2旋转从而驱动中间轴 53 带动第四齿轮 522—起旋转, 而第四齿轮 522啮 合第三齿轮 521 旋转, 从而驱动锯片轴 31 1 带动锯片 31 旋转进行切割工作。
下面结合附图 6-8所示详细说明传动机构 5a 的另一个实施例。本实施方 式中传动机构 5a基本与第一实施例相同, 包括第一级减速机构 51 a、 第二级 减速机构 52a、 用于连接该第一、 第二级减速机构 51a、 52a 的中间轴 53a, 在基准平面上, 马达轴 311 和锯片 31 位于中间轴 53a 的同侧, 所不同的是该 传动机构 5a进一步包括设置在第二级减速机构 52a和锯片轴 311之间的传动 組件 54a。 该传动組件 54a包括设置在锯片轴 311 的第五齿轮 541 a和与第五 齿轮 541a啮合的第六齿轮 542a, 该第六齿轮 542设置在传动副轴 56a上。 其中传动副轴 56a与锯片轴 311 平行,且传动副轴 56a 与支撑平面 21 之间的 距离不小于锯片轴 311 与支撑平面 21 之间的距离。如此抬高了传动副轴 56a, 使之远离支撑平面 21。
第五齿轮 541 a和第六齿轮 542a的直径可以相等,也就是说传动組件 54a 可以只传输动力而不改变传输的速度。当然第五齿轮 541 a的直径也可以小于 第六齿轮 542a 的直径, 从而起到减速的作用。
第一级减速机构 51a包括设置在马达轴上 331 上的第一齿轮 511a、 与第 一齿轮 511a啮合的第二齿轮 512a, 其中第二齿轮 512a设置在中间轴 53a 的 第一端。 中间轴 53和马达轴 331 与锯片平面平行, 且马达轴 331 到锯片平面 的距离不大于中间轴 53到锯片平面的距离。 如此, 使得马达 33 与马达壳体 32更靠近锯片 31, 从而使得结构比较紧凑。
第二减速机构 52a 包括设置在传动副轴 56a 的第三齿轮 521 a、 与第三齿 轮 521a啮合的第四齿轮 522a, 第四齿轮 522a设置在所述中间轴 53a 的第二 二 马达 33和第一级减速机构 51a 的第一、 第二齿轮 511 a、 512a均可旋转 设置在马达壳体 32 中, 第二级减速机构 52a 的第三、 第四齿轮 521a、 522a 和传动組件 54a的第五、 第六齿轮 541 a、 542a 以及传动副轴 56a幸免可旋转 的设置在齿轮箱壳体 55a 内。其中马达壳体 32和齿轮箱壳体 55a 间隔一段距 离, 且分別与固定护罩 34连接。
传动副轴 56a的两端分別通过轴承 58a可旋转的设置在马达壳体 32和齿 轮箱壳体 55a, 其位于马达壳体 32和齿轮箱壳体 55a的中间端上设有保护罩 57a, 该保护罩 57a设置在马达壳体 32和齿轮箱壳体 55a之间且通过两端与 马达壳体 32和齿轮箱壳体 55a 固定连接。
保护罩 57a 遮盖住传动副轴 56a, 该保护罩 57a 可以是完全遮盖住传动 副轴 56a。 但为了安装方便, 在本实施方式中, 该保护罩 57a在靠近锯片 31 的一侧开口, 且保护罩 57a在锯片轴 31 1 的轴向方向上的距离略大于传动副 轴 56a的直径。 在所述中间轴靠近工作台的一侧, 马达壳体 32与中间轴 53 a 的最远距离和齿轮箱壳体 55a 与中间轴 53 a的最远距离均大于保护罩 57a 与 中间轴 53 a的最远距离。 也就是说保护罩 57a所占空间很小, 加上抬高了传 动副轴 56a, 使之远离支撑平面 21。 从而可以防止了传动副轴 56a与护栏 1 1 或底座 1 产生干涉。 从而可以加大了锯机构 3的摆动范围, 同时也为操作者 提供了更好的观察视野。
再参见图 7和图 8所示, 工作时, 通过开关启动马达 33, 马达 33 带动 设置在马达轴 331 a 上的第一齿轮 51 1 a 旋转, 第一齿轮 51 1 a 啮合第二齿轮 51 2a旋转从而驱动中间轴 53a带动第四齿轮 522a—起旋转,而第四齿轮 522 a 啮合第三齿轮 521 旋转, 从而驱动传动副轴 56a 带动第六齿轮 542 a旋转, 而 第六齿轮 542a 与第五齿轮 541 a啮合,从而驱动锯片轴 31 1 带动锯片 31 旋转 进行切割工作。
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。
