Description

复合锯台切式台面防护罩 技术领域
本实用新型涉及复合锯技术领域，尤其是涉及一种复合锯台切式台面防护罩。
背景技术
现有的复合锯台切式台面防护罩，一种是被动的，在工作时按照工件的高度先把台切式防护罩升起到对应的高度再进行切割。还有一种是自动的，台切式防护罩是一体的，台切式防护罩的前面是一个工件导向面，该导向面是向上延伸的弧形面前面很长，工件进入时由工件把它顶起来，该台切式防护罩体积较长，这样就把工件预置的工作台面都占用了。工件无法直接摆放到工作台面上操作非常不便。还有就是防护罩自动打开灵敏度低。因此有必要予以改进。
实用新型内容
针对现有技术存在的不足，本实用新型的目的是提供一种新的复合锯台切式台面防护罩，它即可以防止锯片外露，确保复合锯的安全性，而且操作非常方便，占用空间小，防护罩打开更加灵活，更重要的是为进行加工的工件在台面上预留了摆放空间，使工件可以直接摆放在工作台面上进行操作。
为了实现上述目的，本实用新型所采用的技术方案是：复合锯台切式台面防护罩，它包括有跟刀板、左右辅助罩板和活动罩体，跟刀板和活动罩体分别铰接于左右辅助罩板的两端。
作为上述技术方案的优选，所述左右辅助罩板包括左罩板和右罩板，左罩板和右罩板拼接成左右辅助罩板。
作为上述技术方案的优选，所述左右辅助罩板与活动罩体的铰接处设置有用于驱动活动罩体自动复位的扭簧。
作为上述技术方案的优选，所述左右辅助罩板的底部设置有支撑部。
作为上述技术方案的优选，所述活动罩体的顶部铰接于左右辅助罩板，活动罩体的底部设置有支撑面，活动罩体的外侧设置有工件抵顶面。
采用上述结构后，本实用新型和现有技术相比所具有的优点是：台切式防护罩可以防止锯片外露，增加复合锯的安全性，而且结构简单，成本低，安装和拆卸方便快捷，占用空间小，更加灵活，为进行加工的工件提供更大的预留安置空间，防护罩打开更加灵活，更重要的是为进行加工的工件在台面上预留了摆放空间使工件可以直接摆放在工作台面上进行操作。
附图说明
本实用新型涉及复合锯技术领域，尤其是涉及一种复合锯台切式台面防护罩。
下面结合附图和实施例对本实用新型进一步说明。
图 1 是本实用新型的使用状态示意图之一；
图 2 是本实用新型的使用状态示意图之二。
图中： 1 、面板组件； 2 、框架； 3 、锯片； 4 、跟刀板； 5 、左右辅助罩板； 6 、活动罩体； 7 、支撑部； 8 、工件抵顶面； 9 、支撑面； 10 、机座。
具体实施方式
本实用新型涉及复合锯技术领域，尤其是涉及一种复合锯台切式台面防护罩。
以下所述仅为本实用新型的较佳实施例，并不因此而限定本实用新型的保护范围。
见图 1 和图 2 所示：复合锯台切式台面防护罩，它包括有跟刀板 4 、左右辅助罩板 5 和活动罩体 6 ，跟刀板 4 和活动罩体 6 分别铰接于左右辅助罩板 5 的两端。
左右辅助罩板 5 包括左罩板和右罩板，左罩板和右罩板拼接成左右辅助罩板 5 。
左右辅助罩板 5 与活动罩体 6 的铰接处设置有用于驱动活动罩体 6 自动复位的扭簧。
左右辅助罩板 5 的底部设置有支撑部 7 。
活动罩体 6 的顶部铰接于左右辅助罩板 5 ，活动罩体 6 的底部设置有支撑面，活动罩体 6 的外侧设置有工件抵顶面 9 。
台切式防护罩可以防止锯片外露，增加复合锯的安全性，而且结构简单，成本低，安装和拆卸方便快捷，占用空间小，更加灵活，为进行加工的工件提供更大的预留安置空间，防护罩打开更加灵活，更重要的是为进行加工的工件在台面上预留了摆放空间使工件可以直接摆放在工作台面上进行操作。
下面以本实用新型安装到复合锯上后的使用过程来进一步说明其工作原理：带台切式防护罩的复合锯包括机座 10 、面板组件 1 、框架 2 、锯片 3 和台切式防护罩，框架 2 固定或铰接于机座 10 ，框架 2 相对机座 10 的角度能够调节和改变，面板组件 1 固定于框架 2 ，锯片 3 通过轴承座固定于框架 2 ，锯片 3 由动力装置带动而旋转，面板组件 1 开设有锯片缝，锯片 3 的上半部从面板组件 1 的锯片缝中伸出到面板组件 1 的上表面，台切式防护罩设置在面板组件 1 的上表面。锯片 3 的下半部露出在面板组件 1 的下表面，复合锯通过切换使用状态而分别使用锯片 3 的上半部或下半部。
在使用时，工件置于面板组件 1 的上表面，向锯片 3 所在方向推动工件，（图 2 所示，向左侧推进工件），工件的前端抵顶活动罩体 6 的抵顶面，工件推动活动罩体 6 ，使活动罩体 6 绕第一端的铰接处旋转，进而使活动罩体 6 向左右辅助罩板 5 的内腔旋转，随着工件继续向前推进，活动防护罩 6 推开左右辅助罩板 5 ，使左右辅助罩板 5 绕第一端的铰接处旋转，随着工件的继续推进，工件接触锯片 3 而被锯片 3 切割。
在退出工件后，左右辅助罩板 5 自由落下，活动罩体 6 在扭簧的作用下复位。
面板组件 1 、框架 2 、锯片 3 目前已广泛使用，其它结构和原理与现有技术相同，这里不再赘述。
