Description

锯
技术领域
本发明总体上涉及滑动斜角锯，尤其涉及用于滑动斜角锯的防护栏结构。
背景技术
由于滑动斜角锯可提供比非滑动钭角锯的更大锯割范围而为本领域人所熟知。参看图1-2，一般的现有技术滑动斜角锯有一个底座11，一个连接于此底座11上的可转动工作台12，以及一个锯组件，锯组件具有一个突耳16，一个以枢轴方式与突耳连接的枢转臂17A，一个马达20，一个由该马达20驱动的刀片19，一个覆盖此刀片19上部分的上刀片防护器17，及一个以枢轴方式连接于上刀片防护器17、用于覆盖刀片下部的刀片下防护器18。马达20通常连接于上刀片防护器17。
该滑动斜角锯通常有一个连接于底座11的可动防护栏组件20。组件20沿横向延伸越过工作台12，工件则被面对着此组件安置和支承以便进行锯切作业。可动防护栏组件20包括一个连接于底座11上的固定防护栏21，一个连接于固定防护栏上的可动防护栏22。可动防护栏22通常以可滑动方式连接于固定防护栏21。
此外，滑动斜角锯还有一个使用户能沿工作台12水平地移动锯组件的机构。参看图1，绝大多数滑动斜角锯是通过将锯组件与至少一个导轨15连接来实现水平移动的，导轨以可滑动方式连接于与工作台相连的支承托架14(请参看美国专利US6067885)。
作为一种替换，至少一个导轨15可以如图2所示那样以可滑动方式与工作台12相连。然后支承托架14与该导轨固定连接。此外，支承托架14可如美国专利US5054352所示那样与一个突耳16连接。
在美国专利US5862732中公开了另一种结构，该专利在这里作为一个整体引入参考，其中的导轨15被固定连接于工作台12，支承托架14则(与锯组件)沿导轨15滑动。
采用这类结构，用户就可以朝前推动锯组件，使之朝下运动，然后向后推动锯组件以便切割工件。
发明内容
本发明采用了一种改进了的斜角锯。此锯包括一个底座，一个以可转动方式连接于此底座的工作台，一个可在前、后位置间移动的锯组件，锯组件有一个突耳，一个以枢转方式与突耳连接的枢转臂，一个连接于枢转臂的上刀片防护器(guard)，一个连接于上刀片防护器上的马达及一个由马达驱动的刀片，此锯还有连接于工作台和锯组件中的一个上的支承托架，至少一个以可滑动方式连接于工作台和支承托架中的一个上的导轨，一个连接于底座上的防护栏(fence)组件，此防护栏组件具有一个固定连接于底座上的固定防护栏、一个以可动方式连接于固定防护栏上的可动防护栏，及一个至少被置于固定、可动防护栏两者之一后面的辅助防护栏，可动防护栏确定一个第一支承平面，辅助防护栏则确定一个大体上平行于第一支承平面的第二支承平面。
在下面的附图及详细说明中，将介绍并展现出本发明的其它特点及优点。
附图说明
附图根据本发明的基本原则的具体应用表达最佳实施例，其中：
图1是第一滑动斜角锯的侧视图；
图2是第二滑动斜角锯的侧视图；
图3是本发明的防护器结构的侧视图；和
图4是带有图3所示防护器的滑动斜角锯的部分侧视图。
具体实施方式
现在参照附图详细地介绍本发明，图中相同的数字标注相同的零件。本发明可以安置于任何种类的滑动斜角锯，例如安装在US6067885、5862732或5054352或如图1、2所示的那种滑动斜角锯上。美国专利US6067885、5662732及5054352中的启示均可用作本申请的参考文献。
参看图1-3，滑动斜角锯10也可以有一个连接于底座11上的可动防护栏组件20。组件20最好沿横向延伸过工作台12，工件对着此组件安置和支承以便进行切割作业，组件20可以具有一个连接于底座11上的固定防护栏21，一个连接于固定防护栏上的可动防护栏。可动防护栏22最好以可滑动方式连接于该固定防护栏21上。本领域的熟练人员可以参看美国专利US5297463、5947931，它们均被用作本申请的参考文献。
固定、可动防护栏21、22确定用于支承工件的平面FP，而且固定、可动防护栏最好大体上是共面的。防护栏平面FP最好大体上是垂直的。
此外，底座11和/或工作台12确定一个用于支承工件的平面HP。底座11和工作台12最好大体上是共面的。
固定防护栏21可以有彼此大体上共面的上表面21S。上表面21S最好平行于水平面HP。
在固定、可动防护栏21、22后面配置一个辅助防护栏23是有优点的。辅助防护栏23最好有大体上平行和/或垂直于防护栏平面FP的表面23S。
就此方案来说，用户可以如图4所示那样，取下可动防护栏22，并在底座11和/或工作台12上安置一个垫块24。垫块24最好有与固定防护栏21同样的高度。工件w可以放置于固定防护栏21和垫块24上。工件w也可以靠贴辅助防护栏23放置。
这种结构无需要求附加锯组件行程和/或更长的导轨就可以有效地扩大切割能力。如图4所示，滑动斜角锯10的切割能力大体上为距离CC，也就是在刀片最前端处(点19F)的刀片19与工作台12间的交点和防护栏平面FP之向的距离。
通过在工作台12和/或底座11上放置一个垫块24并将工件W安置在垫块24和固定防护栏21上，工件W被升高到水平面HP之上。由于现在刀片19可以在位置19P处进行切割，这就有效地增大了切割能力，此位置与防护栏平面FP间的距离比刀片19和工作台12间的交点与平面FP间的距离更大。
切割能力也因为工件W的部分被置于防护栏平面FP后面而增大。最好，通过保证在刀片19被置于其行程最后位置(位置19R)时工件W仍能被完全切割，使表面23S被放置得使切割能力最大。
例如在12英寸滑动斜角锯中，切割距离CC可以为14英寸左右。如果固定防护栏和垫块的高度为1.5英寸左右，而且表面23S被置于防护栏平面FP后1.65英寸左右处，此12英寸斜角锯的最终切割距离CC就可约为16.5英寸。
本领域的熟练人员可以认识到可对本申请公开的结构做出其它附加和替换。但是，所有这些附加和替换均被看作是本发明的等同物。
