Description

往复切割工具 技术领域
本发明涉及一种往复切割工具, 特别是涉及一种曲线锯的往复机构。 背景技术
在日本专利 JP45480 1 中揭示有一种曲线锯的往复机构。 请参阅图 3 , 该 曲线锯的往复机构以可枢转的方式连接设置在减速箱 ( 图未示) 内, 其包括 一个可以绕枢转轴 440枢转地的悬架 400 , 该悬架 400 包括顶板 410、 底板 420以及连接顶板 410和底板 420的侧臂, 并且在顶板 410和底板 420上分 别设置有通孔 430、 450 , 用于对设置在通孔 430、 450 内的往复杆 50进行导 向定位。 该往复杆 50上还连接有一个驱动滑块 460 , 该驱动滑块 460位于悬 架 400的顶板 410和底板 420之间, 在受到减速箱内的齿轮组 ( 图未示) 驱 动后, 可以驱动往复杆 50产生如图中竖直方向上的往复运动。
在往复运动过程中, 往复杆 50—直借助悬架 400上的通孔 430、 450导 向定位。 但是, 这种往复机构中, 往复杆 50 的往复移动距离较大。 当滑块 460移动到悬架 400顶端时, 即滑块 460与顶板 410接触, 往复杆 50将从顶 板 41 0上的通孔 430中伸出一段距离,从而影响了整个往复机构的竖直高度, 使得该曲线锯的整体高度较高, 应用性降低。
美国专利 US6625892揭示了另一种曲线锯的往复机构, 其在减速箱内固 定连接有一个悬架, 该悬架包括两个相对地沿垂直方向设置的滑轨, 并且在 两个滑轨上连接有一个滑块。 当滑块受到驱动, 会沿着滑轨而产生垂直方向 上的滑动。 在滑块的底部, 枢转地连接有往复杆, 从而当滑块产生滑动时, 会带动往复杆产生垂直方向上的往复运动。 但是, 由于往复杆缺少悬架的导 向作用, 在使用过程中容易产生振动。
因此, 实有必要对上述往复机构进行改进。
发明内容
本发明的目的在于提供一种结构紧凑, 竖直高度较小的往复切割工具。 为实现上述目的, 本发明提供了一种往复切割工具, 包括马达壳体和与 马达壳体连接的减速箱, 该马达壳体内设置有马达, 该减速箱内设置有往复 机构, 该往复机构包括悬架和通过减速齿轮以及偏心轴与马达连接且受马达 驱动的往复杆, 该悬架包括顶板和底板, 所述往复杆仅与该底板活动连接, 且沿着往复运动的方向上不会超出顶板。
作为对上述方案的进一步改进, 所述底板上设有通孔, 往复杆穿设在该 通孔中; 在往复杆与通孔之间还设置有球轴承。
作为对上述方案的进一步改进, 所述往复杆的自由端连接有滑块, 该滑 块上朝向减速齿轮的一侧,形成有沿着垂直正交于往复运动方向延伸的凹槽, 该凹槽与偏心轴活动配接; 所述悬架还包括连接在顶板与底板之间的滑轨, 所述滑块与该滑轨活动配接, 该滑块可以沿着滑轨滑动。
作为对上述方案的进一步改进, 所述顶板位于减速箱的顶部, 而所述底 板位于减速箱的底部。
作为对上述方案的进一步改进, 所述顶板上设有枢转轴, 所述悬架可围 绕该枢转轴枢转。
由于本发明中的往复杆不再依靠悬架的顶板进行导向定位, 因此在往复 杆的往复运动过程中, 往复杆不会延伸超出悬架的顶板, 可以大大地降低减 速箱的竖直高度, 从而使该往复切割工具的竖直高度减小, 便于应用。

具体实施方式
下面结合附图及具体实施例对本发明作进一步详细说明。
请参阅图 1 , 本发明公开了一种往复切割工具, 在优选的实施方式中, 该往复切割工具为曲线锯。 该曲线锯包括沿水平方向设置的马达壳体 1、 连 接在马达壳体 1 的一端、 呈竖直方向上设置的减速箱 2 以及位于马达壳体 1 下方起支撑作用的支撑板 3。 其中, 马达壳体 1 内设置有马达 1 1 , 该马达 1 1 的马达轴 12与设置在减速箱 2 内的减速齿轮 21啮合配接, 并驱动减速齿轮 21旋转。 在该减速齿轮 21上, 偏心地连接有一个偏心轴 22 , 并且, 该偏心 轴 22 的另一端与竖直设置在减速箱 2 内的往复机构 4 配接。 该往复机构 4 包括往复杆 5 , 当该减速齿轮 21 进行旋转时, 该偏心轴 22将随之做偏心旋 转, 进而驱动往复杆 5沿竖直方向做往复运动。 并进一步地带动安装在往复 杆 5上的锯条 6进行往复切割工作。
另外, 位于减速箱 2下方, 同样受减速齿轮 2 1驱动的一个滚轮 7与锯条 6的背端接触, 当锯条 6做往复运动的同时, 滚轮 7将推动锯条 6向垂直于 锯条 6的往复运动方向移动, 以对锯条 6产生抬刀作用。
请参阅图 2 , 该往复机构 4还包括一个悬架 40 , 该悬架 40包括顶板 41、 底板 42以及相对地连接在顶板 4 1 与底板 42之间的两个滑轨 43。 请一并参 阅图 1 , 该悬架 40的顶板 41位于减速箱 2 内的顶部, 在顶板 41上设有枢转 轴 44 , 从而使该悬架 40可以在减速箱 2 内绕枢转轴 44枢转。 该悬架 40的 底板 42位于减速箱 2 内的底部, 因此, 整个减速箱 2的竖直高度大致上等于 悬架 40的竖直高度。
请继续参阅图 2 , 在悬架 40的底板 42上设有通孔 45 , 往复杆 5穿设在 该通孔 5 中, 并且对往复杆 5起导向定位作用。 为了便于往复杆 5的滑动, 在往复杆 5与通孔 45之间还设置有球轴承 48。 该往复杆 5位于悬架 4的顶 板 41 和底板 42之间的部分, 其自由端还连接有一个滑块 46 , 该滑块 46与 滑轨 43滑动配接, 从而可以沿着滑轨 43上下滑动, 而且, 在该滑块 46朝向 减速齿轮 21 的一侧, 还形成有沿垂直正交于往复运动方向延伸的凹槽 47 , 供连接减速齿轮 21 的偏心轴 22插入配接, 从而使该滑块 46 受减速齿轮组 21 的偏心旋转驱动, 而沿着滑轨 43 上下往复滑动, 并进一步带动往复杆 5 和安装在往复杆 5末端的锯条 6往复运动以进行切割操作。
需要说明的是, 该滑块 46的移动被限制在悬架 40的顶板 41 和底板 42 之间。 因此, 当滑块 46滑动至接触底板 42时, 往复杆 5带动锯条 6相对于 减速箱 2产生最大的垂直距离。 此时, 往复杆 5超出悬架 40的底板 42的部 分接近于零; 而当滑块 46滑动至接触顶板 4 1 时, 往复杆 5带动锯条 6则相 对于减速箱 2产生最小的垂直距离。 此时, 往复杆 5 虽然超出悬架 40的底板 42 , 但是仍然不会超出悬架 40的顶板 41 , 从而在竖直方向上减小了减速箱 2 的高度, 便于操作者应用。
