图 1为本发明提供的键帽的结构示意图， 为了清楚描述其结构， 图中 还示出与键帽相连的键柱。
图 2为本发明工件制作机一实施例结构示意图。 具体实施方式
现通过实施例并结合附图对本发明作进一步说明。
如图 1所示， 本发明提供的键帽包括由竹材制成的竹制帽体 24, 竹制 帽体 24的底壁上设有连接部， 连接部为下大上小的子母式圆形沉孔 22。 竹制帽体 24通过子母式圆形沉孔 22与键柱 21上的圆柱形连接部 23配合， 与键柱 21连接构成按键； 连接部的具体结构可以根据实际需要及键柱 21 上部结构的不同设置为其他具体结构， 比如说： 可以是单独的圆形沉孔。 竹制帽体 24 其四方侧面中的连续三方侧壁的上部向上内侧方向倒角形成 倾斜面 25 , 也可以通过倒角形成弧面。 竹制帽体 24其上表面形状与人手 指的预定部位的形状相对应， 所述预定部位可以为手指指肚。
本发明键帽的制作方法是： 先制作其宽度、 厚度为分别与需要加工制 作的竹制帽体的相应宽度和厚度相当、 相对两侧边分别倒角成与竹制帽体 的相应两侧边形状相同、 长度为需要加工制作的竹制帽体的长度或宽度的 若干倍的坯件。 再将坯件底面向上置于工件制作机的工作台面上， 由工件 制作机的预定刀刃具自坯件一端起依次对坯件进行横向倒角、 竖向钻孔、 横向切割等加工处理工序制得竹制帽体， 重复此操作， 直至将所制作的坯 件逐个地加工成多个键帽。
本发明提供的工件制作机如图 2所示。 两工作台 la、 lb呈一前一后相 互对应设于机架 11上， 后工作台 lb台面上呈前后方向设有一条贯通式凹 槽 13 , 前工作台 la台面上对应于凹槽 13设有一凸块 12。压轮 4对应于凹 槽 13通过由套筒 5和设于套筒 5内的压缩弹簧连接于机架 11。 其钻头为 子母式的钻具 8, 钻具 8位于前工作台 la上方， 且对应于凹槽 13连接于 机架 11。 限位开关 7连接于机架 11 , 并对应于其钻头为子母式的钻具 8。 一左一右相互对应的两个盘式齿形刀 2和 3位于两工作台 la、lb之间， 两个盘式齿形刀 2和 3通过刀架 9活动连接于导轨 10上， 导轨 10连接于 机架 11。右方盘式齿形刀 3盘面垂直于工作台 lb台面，左方盘式齿形刀 2 盘面相对于右方盘式齿形刀 3盘面向上前方倾斜一角度。 其倾斜的角度即 为工件端面倒角的角度。
工作时，通过凹槽 13和压轮 4将作为工件的竹材坯件 6稳定于工作台 lb上； 坯件 6前进至其一端端面处于左方盘式齿形刀 2处时， 刀架 9起动 右行， 由左方盘式齿形刀 2右进刀实现坯件 6的横向倒角； 坯件 6继续前 进至凸块 12处时，其钻头为子母式的钻具 8为坯件 6进行竖向钻孔，其钻 具 8的行程及形成孔的深度由限位开关 7控制。 钻孔完毕后刀架 9起动左 行， 由右方盘式齿形刀 3左进刀切割坯件 6, 进行横向切割， 即完成一个 键帽的加工制作。 如此重复上述动作实现键帽的自动连续生产。 所需切割 的键帽长度由凸块 12的设置的位置确定。上述横向倒角、竖向钻孔及横向 切割仅是对于上述实施例的说明， 本领域技术人员还可以根据实际需要， 进行倒角、 钻孔和切割； 另外， 还可以根据实际生产需要， 对盘式齿形刀、 钻具等刀刃具以其他方式进行布置。
本发明的另一实施例提供的工件制作机中， 位于两相对应的工作台之 间的两刀刃具分别通过相应的刀架连接于相互独立的两导轨上。
本发明的再一实施例提供的工件制作机中， 两相对应的工作台分别连 接于两个相互独立的机架上。 工作时， 合并两机架使两工作台相互对应。 该实施例提供的工件制作机使用、 保管极为方便。
