Description

台锯 技术领域

背景技术
对于脆性的工件, 传统的台锯通常只 能对其进行粗切割 , 切割完 成后, 工件的切割面的底端会有锯齿状崩边, 不能达到要求的精细加 工效果。
为解决上述问题, 通常的做法是再将经台锯粗加工过的工件用其 他工具进行二次加工, 使其切割面达到要求的平整和精确度, 然而, 这样做需要将工件反复移动, 尺寸需经过多 次对准, 操作繁瑣, 加工 时间也较长。 为克服这些不足, 该领域的技术人员 也做了其他的改进, 如在台锯的主圆锯片 的前端增加一组马达和较小的辅圆锯片 , 在工件 推向主圆锯片之前, 先由辅圆锯片 将工件的底部切割 出一条缝隙, 然 后再由主圆锯片 将其切断, 这样, 主圆锯片 的切割工作的作用底端上 移到 了 工件的较中 间的位置, 工件的底端就不会出现崩边。 然而该装 置也有明显的缺陷, 它较普通的 台锯增加了 一组马达和锯片 , 造成内 部结构复杂, 造价昂贵, 使用成本较高, 并且, 工件上的主圆锯片 和 辅圆锯片 的切割轨迹的交汇处依然会出现不平整的情况。

具体实施方式
下面结合图 1 至图 6 来描述本发明 的台锯的第一个优选方案, 以 说明本发明 的创作构思。
如图 1 , 台锯 1 包括工作台 10, 工作台 10 包括工作表面 11 和侧 沿 13。 工作表面 11 呈长方形 , 具有平行于其 自 身长边的轴线 X 和平 行于 自 身短边的轴线 Y , 还具有垂直于工作表面的轴线 Z。 从工作表 面 11 沿 Z 轴向上的方向定义为 台锯 1 的上方, 从工作表面 11 沿 Z 轴 向下的方向定义为 台锯 1 的下方, 沿 Y轴向 图左侧的方向定义为 台锯 1 的前方, 沿 Y轴向 图右侧的方向定义为 台锯 1 的后方。
工作台 10 的侧沿 13 上安装有外框 131 , 外框 131 包括固定连接 侧沿的 固定外框 133 和枢轴连接所述固定外框 133 的活动外框 135 , 固定外框 133 和活动外框 135 在水平方向上平齐, 活动外框 135 的大 部分在 Y轴方向上超出 工作台 10 , 起到延展的工作的表面的作用 , 所 述活动外框 135还可以朝向所述固定外框 133枢转并覆压在工作表面 11 上, 起到节省空间的作用 。 所述外框 131 上可滑移的安装有工件抵 靠装置 4 ,工件抵靠装置 4 包括两个可滑移的对应安装在固定外框 133 的两个侧边 134 上的滑架 43 和设置在两个滑架 43 之间的挡板 41 ,挡 板 4 1 平行于 X轴, 挡板 41 的前端面或后端面垂直于工作 10 , 形成 供工件抵靠的工件抵靠面; 工件抵靠装置 4 还包括设置在其中一个滑 架 4 3 上的锁定手柄 45 ,所述锁定手柄 45 用 于可选择的将工件抵靠装 置 4 锁定在合适的位置上, 或者解锁所述工件抵靠装置 4 使其可以 沿 Y轴方向在外框 131 上滑移, 其实现方式为业界所熟知的凸块压 1紧 结构 , 在此不进行详细描述。
优选的, 外框 131 上贴有标尺 ( 图 未示 ), 用 以标示工件的切割或 刨 削尺寸 , 确定工件抵靠装置 4 的位置, 以加工工件到合适的尺寸。
台锯 1 还包括位于工作台 10 下方的工作腔 15 , 工作腔 15 下方连 接有两组可折叠的支撑架 17 , 每组支撑架 17 包括两个支脚 171 和连 接两个支脚的连杆 173。 工作腔 15 的前端下方连接有两个滚轮 177 , 当 两组支撑架 17 折叠时, 可通过滚轮 177 方便移动台锯 1。
台锯 1 的工作腔 15 内安装有切割装置 3 (参见图 3) , 工作腔 15 的外壁上设有切割装置 3 的电源按钮 31。
台锯 1 的工作表面 11 上安装有电刨 2 , 电刨 2 具有壳体 21 和刀 轴 23 ( 参见图 6 )。 安装后, 电 2 相对于工作台 10 的位置是固定的 , 在电刨 2 工作时, 刀轴 23 旋转形成一个位置 固定的刨 削线, 该刨 削 线平行于 Z 轴, 如业内 所公知的, 刀轴 23 的刃部较突出 于其他部分, 所以刨 削线即为刀轴 23 的刃部在旋转时形成的远离 电刨 2 的壳体 21 的最外端。 在电刨 2 工作时, 工件沿着平行于 X轴的方向被推进, 所 以刨 削线与 X轴相交形成电刨 2 工作时的工作面, 工件超出 于工作面 的部分被刨 削 , 而 不超出 于工作面的部分被保留。
如图 2 , 工作台上设有第一安装机构 19 , 在本实施例中具体为 两 个螺孔 19 , 两个螺孔 19 连接而成的直线位于 X 轴方向上; 电刨 2 上 对应的设置有第二安装机构 29 , 在本实施例 中具体为设置在壳体 21 上的两个通孔 291 和适宜于穿过所述通孔 291 安装在所述螺孔 19 中 的两个螺柱 292。 通过上述相配的螺孔 19 和螺柱 292 , 电刨 2 可拆卸 的安装在工作台 10 上。 第一安装机构 19 和第二安装机构 29 具有有 多种可选的具体实施方式, 如: 第一安装机构 19 可以为 凹槽, 第二 安装机构 29 则为对应设置的凸块, 在此不再——描述。 工作表面 1 Q 上设有一个长槽 191 和一个短槽 192 , 长槽 191 和短 槽 192 相连通, 长槽 191 是一个连通工作腔 15 的通孔, 短槽 192 是 设于工作台 10 上的一个凹台 , 其形状和电刨 2 的壳体 21 的下方的凸 台 214 (参见图 5 )形状相配。 一个长板 193 和一个短板 194 的形状分 别和长槽 191和短槽 192 的形状相配,适宜于盖在长槽 191和短槽 192 上。 当切割装置 3 工作时, 长板 193 移开以露出长槽 191、 短板 194 盖上短槽 192 ; 当 电刨 2 工作时, 长板 193 盖上长槽 191 , 短板 194 移开以露出短槽 192。
如图 3 , 切割装置 3 包括第一马达 ( 图 未示 ), 和被第一马达驱动 进行切割动作的锯片 33 , 在本实施例中具体为一种圆锯片 33 , 圆锯 片 33 大致平行于 X轴, 且可以在 Z 轴方向上上下移动; 向上移动后, 可穿过长槽 191 部分位于工作表面 11 上, 向下移动后, 可位于工作 表面 11 下。 其上下移动的实现方式为本领域技术人员 所熟知的, 在 此不再详细描述。 在切割装置 3 工作时, 圆锯片 33 旋转切割工件, 由于圆锯片 33 本身的厚度, 圆锯片 33 切割形成前后两个切割面, 圆 锯片 33 靠近工作台 10 前端的一侧为前切割面, 靠近工作台 10 后端 的一侧为后切割面。 前切割面和后切割面均平行于 X轴与 Z 轴相交形 成的平面, 并垂直于工作台 10。 如业内 所公知的, 切割装置 3 工作时 工件位于前切割面和后切割 面之外的部分被切割下来, 而依据实际的 工作情况, 前切割 面和后切割面中较非近工件抵靠装置 4 , 也就是工 件的起始位置的一个切割面是圆锯片 3 3 的工作面 , 工件超过该工作 面的部分被切割掉, 而不超过该工作面的部分被保留。
优选的, 电刨 2 的刀轴 23 的位置和安装位置经过预设, 使得刨 削 线基本上位于前切割 面上。 由于制造和装配误差的存在, 实际上不可 能做到刨 削线完全准确的位于前切割面上, 然而, 其误差是在加工需 要的允许误差范围之内 的, 即刨 削线基本上位于前切割面上。 这样, 电刨 2 安装在工作表面 11 并工作时, 若工件抵靠装置 4 位置 固定, 刀轴 23 到工件抵靠装置 4 的最短距离 即为刨 削线到工件抵靠装置 4 的距离 , 该距离和圆锯片 33 部分位于工作表面上方并工作时到工件 抵靠装置 4 的距离相等。 这样可以使得分别切割和刨 削工件时, 圆锯 片 33 和刀轴 23 的工作面基本位于同一个平面上。 在切割完成后, 微 调工件抵靠装置 4 , 即可进行刨 削工作, 并且, 工件抵靠装置的位移 量即为刨 削量。
在本实施例中 , 仅有一组位于圆锯片 3 3 后方的第一安装机构 1 9 , 这使得电刨 1 刨 削工件时, 工件抵靠装置 4 相对于刀轴 2 3 位于工作 台 1 0 的前端, 圆锯片 3 3 到工件抵靠装置 4 的距离 即为前切割面到工 件抵靠装置 4 的距离 ; 然而可选的 , 第一安装机构 1 9 也可位于圆锯 片 3 3 的前方, 使电 2 刨 削工件时, 工件抵靠装置 4 相对于刀轴 2 3 位于工作台 1 0 的后方, 此时刀轴 2 3 的刨 削线须位于圆锯片 3 3 后切 割 面上, 这样, 电刨 4 和圆锯片 3 3 分别工作时, 若工件抵靠装置 4 位置固定, 刀轴 2 3 到工件抵靠装置 4 的最短距离和圆锯片 3 3 到供工 件抵靠的工件抵靠装置 4 的距离依然是相等的; 工作台 1 0 也可同 时 具有上述两种位置的两组第一安装机构 1 9 , 然而, 其设置方式需使得 电刨 2 安装在任一组第一安装机构 1 9 上时, 刀轴 2 3 工作时的刨 削线 基本位于圆锯片 3 3 工作时的切割面所在的平面中 , 即若工件抵靠装 置 4 位置固定, 刀轴 2 3 到工件抵靠装置 4 的最短距离和圆锯片 3 3 到 工件抵靠装置 4 的距离是相等的。
通过上述优选的电刨 2 安装方式, 台锯 1 可以拥有一种优化的工 作流程, 其具有粗加工阶段和精加工阶段, 在粗加工阶段, 操作者首 先确定长板 1 9 3 离开长槽 1 9 3 , 短板 1 9 4 盖上短槽 1 9 2 , 上移圆锯片 3 3 到工作表面 1 1 以上合适位置, 然后参照标尺调节工件抵靠装置 4 到合适的位置, 再将工件的一端抵靠在工件抵靠装置 4 上并沿工件抵 靠装置 4 向 圆锯片 3 3 滑移, 使圆锯片 3 3 旋转切割工件。 工件被切断 后, 断面若是粗糙的 , 可以进一步进入精加工阶段进行加工, 此时, 下移圆锯片 3 3 到工作表面 1 1 以 下 , 用长板 1 9 3 盖上长槽 1 9 1 , 从短 槽 1 9 2 上将短板 1 9 4 移开, 通过螺柱 2 9 2、 螺孔 1 9 安装好电刨 2 , 然 后根据情况滑移工件抵靠装置 4 , 使其向 电刨 1 方向进行微调 , 然后 开启 电刨 2 , 再将工件的一端抵靠在工件抵靠装置 4 上并沿工件抵靠 装置 4 向刀轴 2 3 滑移, 使刀轴 2 3 对工件进行刨 削加工, 由于刨 削线 位于前切割 面上, 工件抵靠装置 4 向 电刨 1 移动的距离就是刨 削力口工 的尺寸 这样, 经过粗力口工和精力口工, 可以得到断面平整, 尺寸精确 的工件。 切割装置 3 和电刨 2 也可各 自 独立的进行工作, 然而它们不可以 同 时工作。
下面具体描述本发明 中 的电刨 2 的结构。
如图 4 和图 5 所示 , 电刨 2 的壳体 21 由上而下 包括马达罩 213 , 上壳体 211 , 下壳体 212 , 它们通过螺钉螺孔装置依次连接在一起。 下壳体 212 的底部设有一个向下凸 出 的凸台 214 , 在电刨 2 安装在工 作台 10 上时, 凸台 214 安放于工作台 10 的短槽 192 中 , 刀轴 23 安 装在上壳体 211 的顶部和下壳体 212 底部的凸台 214 之间 , 在电刨 1 安装在工作台 10 上时, 刀轴 23 的底端略低于工作台 10 的工作表面, 这样, 刀轴 23 可以无死角 的刨销到工件的底部, 避免了 由刀轴 23 和 工作表面 10之间存在缝隙而导致的工件底部刨 削 不完全的现象。
如图 4 和图 5 所示, 壳体 21 具有一个上壳体 211 的顶端形成上表 面 215 和一个适宜于面向并抵接工件的刨 削表面 217。 马达罩 213 设 于上表面 215 上, 其中安装有第二马达 ( 图 未示 )。 上表面 215 上还 设有带轮罩 216 和前述的两个通孔 291 , 所述通孔 291 可容纳所述的 两个螺柱 292。
优选的, 通孔 291 设置为在 Y 轴方向上略长的腰形孔, 这样, 电 刨 2 安装后可以在 Y 轴方向上小幅的移动, 以调节刀轴 23 , 使其刨 削 线精确的位于圆锯片 33 的切割面上。 为 了精确的调节电刨 2 位置, 电刨 2 和工作台 10之间设有一个校准装置 293 (参见图 6 ) , 校准装置 293 包括与工作台 10相对固定的底座 294和与 电刨 2相对固定的调节 螺杆 295 , 调节螺杆 295 以螺紋螺杆配合的形式安装在底座 294 上, 可以通过旋转调节螺杆 295 进行轴向的移动并带动电刨 2在 Y轴上小 幅的移动,校准刀轴 23。该校准装置 293 是本领域技术人员 所熟知的 , 其进一步的细节在此不再赘述。
刨 削表面 217 上间 隔排布了 三个沿 Z 轴方向设置的狭槽, 依次为 安装第一导轮 251 的第一导轮槽 252 , 安装刀轴 23 的刀轴槽 231 , 安 装第二导轮 253 的第二导轮槽 254。所述刀轴 23 径向略突出 于刨 削表 面 217。 所述的第一导轮 251 和第二导轮 253 为 大小和形状相同 的 圆 柱体, 径向可伸缩的安装在壳体 21 中 , 其直径大于第一导轮槽 252 和第二导轮槽 254 的宽度。 第一导轮 251 和第二导轮 253 可绕其 自 身
8 纵向轴线枢转。 所述第一导轮 251 和第二导轮 253 完全伸出 时, 其在 Y轴方向上突出 于刨 削表面 217外的长度不小于刀轴 23在 Y轴方向上 突出 于刨 削表面 217 外的长度; 第一导轮 251 和第二导轮 253 受到压 迫时可完全缩回到刨 削表面 217 内 。 在刨 削工件时, 工件压迫第一导 轮 251 和第二导轮 253 缩回到刨 削表面 217, 第一导轮 251 和第二导 轮 253 也施加给工件一个反作用 力 , 使工件紧贴向工件抵靠装置 (4) , 以提高刨 削过程中 的准确度和稳定度。 进一步的 , 在本优选实施例中 , 第一导轮 251 和第二导轮 253 均采用摩擦力较大的橡胶材料, 这样工 件在刨 削推进过程中会带动第一导轮 251 和第二导轮 253绕其 自 身纵 轴线枢转, 使进料过程更加平滑稳定。
刨 削表面 217 上还安装有一个安全护罩 26, 所述安全护罩 26 通 过销轴 261 安装在刨 削表面 217 —侧, 可绕该销轴 261 在一个打开位 置和一个关闭位置间转动, 在所述的关闭位置安全护罩 26 遮盖住所 述的刀轴槽 231 ,所述的打开位置安全护罩 26 离开所述的刀轴槽 231。 无论电刨 2 是否启动, 所述的第一导轮 251 和第二导轮 253 均伸出 刨 削表面 217 外, 安全护罩 26 位于关闭位置, 以起到安全防护的作用 ; 仅当工件从销轴 26 所在的一侧贴紧刨 削表面 217 向另 一侧推进时, 安全护罩 26 会被推到打开位置, 第一导轮 251 和第二导轮 253 会被 工件压迫缩回到刨 削表面 217 内 , 刀轴 23 刨 削工件。 在刨 削过程中 , 工件本身形成了对刀轴 23 的遮盖, 而刨 削完成后, 第一导轮 251 , 第 二导轮 253 , 安全护罩 26 回复到原位, 这样, 在从刨 削的准备到完成 的过程中 , 操作者始终是安全的。
下面参照图 6 描述电刨 2 的具体结构。 马达罩 213 内 的第二马达 具有马达输出轴 ( 图未示 ), 马达输出轴上套装有一条皮带 22, 皮带 22 还套接一个带轮 232 , 所述带轮 232 位于电刨 2 的上表面 215 上, 并安装在刀轴 23 的穿过上壳体 211 的刀轴上端 233 上, 所述刀轴 23 还具有一个安装在下壳体 212 底部的刀轴下端 234。通过上述的结构, 第二马达的旋转输出通过皮带 22 和带轮 232 传递到刀轴 23 上, 使刀 轴 23 进行旋转的刨 削运动。 所述上表面 215 上还安装有遮盖所述皮 带 22 和带轮 232 的带轮罩 216。
所述的第一导轮 251 和第二导轮 253 安装在上壳体 211 和下壳体 212 之间 , 刀轴 23 的两侧, 它们的结构和安装方式相同 , 下面以第一 滚轮 251 为例进行描述,第一导轮 251可枢转的安装在第一导轮架 241 上, 第一导轮架 241 具有第一主轴 242, 第一主轴 242 上可枢转的安 装在上壳体 211 和下壳体 212 之间 , 下壳体 212 上设有一个第一凸壁 244 , 第一凸壁 244 和第一主轴 242 之间设有第一弹簧 243, 第一弹簧 243 设置的可推动所述第一主轴 242 枢转并进一步推动所述第一导轮 251 突出 于刨 削表面 217 外。 电 2 还具有相对于刀轴 23 对称安装的 第二导轮架 281 , 第二主轴 282 , 第二凸壁 284 , 第二弹簧 ( 图未示 )。
所述安全护罩 26通过销轴 261安装在上壳体 211部分的刨 削表面 217 —侧, 安全护罩 217 和上壳体 211 之间安装有一个扭簧 262 , 所 述扭簧 262 压迫安全护罩 26 位于关闭位置。
上壳体 211 和下壳体 212 之间还安装有集尘装置 219 , 其具体结 构与本发明 的主要 目 的无关, 在此不作进一步的描述。
下面结合图 7、 图 8 来描述本发明 的台锯的第二个优选方案, 以 进一步说明本发明 的创作构思。
如图 7 , 电刨 2 安装在远离长槽 191 的后方, 电刨 2 的切割线与 圆锯片 33 的切割面不再位于同一个平面上。 此时, 外框 131 上设有 可沿 Y 轴滑移并可在预设的位置 固定的标尺 5。 标尺 5 可在设于外框 上的凹槽 ( 图未示 ) 中滑动, 其固定方式为业界所熟知的螺栓压紧结 构 ( 图未示 ), 在此不再赘述。 标尺 5 具有至少一个 0 刻度线, 作为 度里工件尺寸的基准刻度。 在电刨 2 工作时, 操作者可移动标尺 5 使 其基准刻度 0 刻度线与 电刨 2 的切割线, 即刀轴 23 工作时靠近工件 抵非装置 4 的最外侧对齐。
如图 8 , 电刨 2 脱离工作台 10。 标尺 5 的基准刻度 0 刻度线对齐 切割装置的切割面, 即对准圆锯片 33 靠近工件抵靠装置 4 的最外侧。
本实施方式具有一种优选的工作流程, 即: 首先, 将切割装置 3 置于工作状态, 操作者调节标尺 5 位置使标尺 5 的基准刻度 0 刻度线 对准圆锯片 33 的切割面, 然后根据工件的切割需要调节工件抵靠装 置 4 到合适的位置并切割工件, 该位置会具有一个标尺 5 上的标示刻 度; 随后, 将电刨 2 置于工作状态, 调节标尺 5 使其 0 刻度线对准电 刨 2 的刨 削线, 然后根据标示刻度调节工件抵靠装置 4 到合适位置并 刨 削工件。
本实施方式的刨 削线与切割 面虽然不在同 一个平面上, 然而通过 设置位置可调节的标尺 5 , 使得台锯 1 在切割工件和刨 削工件时标尺 5 的 0 刻度线分别与切割面和刨 削线平齐, 具有相同 的基准刻度, 进 而在刨 削时可以参考切割时的标示刻度。
本发明 尚有多种具体的实施方式。 凡采用等同替换或者等效变换 而形成的所有技术方案, 均落在本发明要求保护的范围之内 。
