具体实施方式
图 1为一种与手持式切割机 1配合的工作台 10, 工作台 10可以支撑被切 割工件和导向手持式切割机 1的切割。
工作台 10包括底座 11, 可旋转的连接底座 11的转臂 50 , 由转臂 50支撑 的导轨 80。 底座 11的第一支撑平面 17和转臂 50上的第二支撑平面 51共同支 撑待切割的工件,导轨 80和手持式切割机 1的底板 7相配以引导手持式切割机 1沿着预定的轨迹切割工件, 预定的轨迹通常为直线。
图 2为工作台 10和相配合的手持式切割机 1的分解示意图。
如图 2, 手持式切割机 1 包括用于加工工件的工作头 3 ; 用于驱动该工作头 3旋转以加工工件的马达(图未示);用于收容马达和至少部分工作头 3的壳体 6 ; 抵靠于工件或导轨 80、 支撑手持式切割机 1进行切割等加工工作的底板 7 ; 安 装于壳体 6前部的护罩 9 , 护罩 9设有开口, 工作头 3可选的从该开口露出以 加工工件。 在本实施方案中, 护罩 9的底部形成前述的底板 7 , 并具有开口。 护罩 9可相对于壳体 6前部在两个位置之间移动, 当护罩 9位于第一位置时, 工作头 3未露出于开口; 当护罩 9位于第二位置时, 工作头 3至少部分的露出 于开口。 如此通过护罩 9相对于壳体 6前部的移动来调节工作头 3露出护罩 9 的深度, 从而可以设定切割工件的深度。
在本实施例中, 手持式切割机 1为一种电圓锯, 工作头 3具体为一个圆形 的锯片。
继续参照图 2, 导轨 80具有沿纵长方向延伸的导向平面 81 , 导向平面 81 上具有沿纵长方向延伸的切割槽 89 , 手持式切割机 1的底板 7可以直接接触该 导向平面 8 1并可相对该导向平面 81沿纵长方向滑动, 手持式切割机 1的工作 头 3从切割槽 89中穿过并可沿切割槽 89的纵长方向移动。导向平面 8 1的两侧 设有垂直于导向平面 81向上延伸的侧挡板 87 , 两个侧挡板 87相互平行、 并平 行于切割槽 89。 两个侧挡板 87之间的宽度和手持式切割机 1的底板 Ί的宽度 相当,以结合导向平面 81 引导手持式切割机 1的底板 Ί和工作头 3沿纵长方向 直线移动。 在本实施方式中, 本实施方式中的手持式切割机 1的工作头 3并非 位于底板 7的中间位置, 因而, 导向平面 8 1上的切割槽 89也并非位于导向平 面 81的横向方向的中间位置, 而是更靠近其中一侧的侧挡板 87, 以和手持式 切割机 1相配。本领域技术人员可以合乎实际的更改切割槽 89的位置以和各种 手持式切割机 1的底板 7和工作头 3相配。
导轨 80纵长方向上的两端边缘向上凸起,限制手持式切割机 1的轴向移动, 进一步地,一端形成一个弧形凸块 83, 另一端形成一个线形凸块 85。 弧形凸块 83和线形凸块 85中空, 在导轨 80的底部对应的形成一个弧形 W槽和一个线形 凹槽。 弧形凹槽和线形凹槽配接于转臂 50上的相应的弧形配接部 53和线形配 接部 55 , 以将导轨 80可移除的安置在转臂 50上。
导轨 80的背面两侧分别设有一个沿纵长方向延伸的阻尼条(图未示), 阻尼 条用于增加导轨 80安放于工件上时的摩擦力, 以利于稳定的切割。 导轨 80也 可以脱离工作台 10单独安放在工件上使用。
继续参照图 2 , 转臂 50具有沿转臂 50 自身的纵长方向延伸的第二支撑平 面 51 , 第二支撑平面 5 1用于支撑待加工工件, 它的两端分别设有前述的弧形 配接部 53和线形配接部 55, 弧形配接部 53和线形配接部 55阶梯状向上凸起, 分别具有第一级凸台 57和从第一级凸台 57的中间向上凸起, 可相配的容纳于 弧形凹槽和线形凹槽的第二级凸台 59, 弧形配接部 53和线形配接部 55的两个 第一级凸台 57高度相同、 两个第二级凸台 59高度也相同。 这样, 导轨 80的弧 形凹槽和线形凹槽分别盖在弧形配接部 53和线形配接部 55的第二级凸台 59 上, 弧形凹槽和线形凹槽的边缘端面并被第一级凸台 57支撑, 形成和转臂 50 接触的接触面, 将导轨 80中间悬空的架在转臂 50上。该接触面和导轨 80的底 面是平齐的。 通过以上的方式的设置, 导轨 80可操作的相对于转臂 50在第一位置和第 二位置间移动, 在第一位置, 导轨 80与转臂 50连接, 弧形凹槽和弧形配接部 53配接, 线形凹槽和线形配接部 55配接, 前述的接触面被支撑在弧形配接部 53和线形配接部 55的第一級凸台 57上,在导轨 80的底面和转臂 50的第二支 撑平面 51之间形成一个高度恒定的间隙,待加工的工件放置于该间隙中, 被支 撑于第二支撑平面 51上, 位于导轨 80底面下。 间隙的高度等于第一级凸台 57 的高度。 在第一位置, 导轨 80导向手持式切割机 1轴向移动以加工工件。 在第 二位置, 导轨 80与转臂 50脱开连接。 在本实施方案中, 操作者只需简单的向 上拿起导轨 80 , 就可以将导轨 80从第一位置移动到第二位置。 这样的设置提 供了工作台 10的一种简单方便的使用方法, 第一步, 将导轨 80从第一位置移 动到第二位置; 第二步, 将工件放置到第二支撑平面 51上; 第三步, 将导轨 80从第二位置移动到第一位置; 第四步, 将手持式切割机 1沿导轨 80移动加 工工件。 整个操作方法不需额外的工具和导轨 80的调高过程。
在本实施方式中, 待加工的工件的高度优选的不高于间隙的高度, 然而可 以低于间隙的高度。 为了防止加工过程中工件受到工作头 3的大的向上提拉工 件的力, 使工件不稳、 操作困难, 本实施方式优选的使用电圆锯, 其工作头 3 为圓形的锯片, 其加工工件时主要是由环形连接多个锯齿周而复始的向下切割 工件, 向上提拉工件的力相对很小, 只需施加一个扶持的力即可稳定工件。 然 而, 本领域技术人员所习知的, 手持式切割机 1也可以为角磨等。
转臂 50的第二支撑平面 51上和切割槽 89对应的设置有纵长方向延伸的长 槽 63 , 工作头 3可穿过切割槽 89切割工件后进入到长槽 63中, 长槽 63的深 度设置得略深于工作头 3可以达到的最低位置, 以避免手持式切割机 1加工工 件时切伤转臂 50。 由于导轨 80的切割槽 89偏向一侧的设置在导向平面 81上, 因此长槽 63也偏向一侧的设置于转臂 50的主体上。 长槽 63从线形配接部 55 一侧起始, 向弧形配接部 53—侧延伸, 末端连通到一个枢转孔 61。 该枢转孔 61的枢转轴线垂直于第二支撑平面 51 ,枢转孔 61枢转连接设置于底座 11上的 枢转轴 35 , 通过枢转孔 61和枢转轴 35的配合, 底座 11和转臂 50结合形成一 个类似钟摆的结构, 转臂 50的纵长部分绕垂直于第二支撑平面 51的枢转轴 35 相对于底座 11摆动。 转臂 50上靠近弧形配接部 53的一侧以枢转孔 61为圆心 形成一个转盘 65 , 转盘 65容纳于底座 11下方空间, 枢转轴 35的周围。
转臂 11的末端, 弧形配接部 53的靠近底座的端面上设有角度确定件, 具 体为一个略突出于弧形配接部 53端面的钢球。 底座的与弧形配接部 53对接的 内侧面上的数个特定位置设有凹槽, 这样, 当转臂 11转动到特定的位置, 钢球 落入凹槽, 操作者可以感知到定位。 凹槽的位置经过特别的设定, 使得当转臂 和挡板的夹角到达 45度, 90度, 135度时, 钢球落入凹槽。 这样的设置可以使 操作者更直观的确定转臂到达了需要的角度, 也增加了转臂定位的准确性。
底座 11呈台阶状, 具有高台面 15和低台面 13。 高台面 15的纵向延伸的 一侧壁中间向外拱起形成换形部, 另一侧壁形成一个护栏 19。 低台面 13的表 面形成与转臂 50的第二支撑平面 51平齐的第一支撑平面 17 , 高台面 15和低 台面 13之间的阶梯连接部形成前述的高台面 15的护栏 19 , 护栏 19的表面形 成供工件抵靠定位的工件抵靠面。 第一支撑平面 17中间断开形成一个断口, 以 容纳转臂 50在其中转动。 断口的两个边缘对称, 均垂直于第一支撑平面 17 , 且均相对于护栏成 45度角, 形成两个相互垂直的角度限位壁 25。 转臂 50上长 槽 63的两側, 转臂 50的两个侧壁 69的邻接转盘 65的部分相对应的设置的到 长槽 63的距离相等。 两个侧壁 69的邻接转盘 65的部分的间距设置得使转臂 50恰好可以在缺口中具有 90度的转动范围, 在一个极限位置一个侧壁 69抵靠 在一个角度限位壁 25上, 在另一个极限位置另一个侧壁 69抵靠在另一个角度 限位壁 25上, 且长槽 63相应的平行于側壁 69抵靠的角度限位壁 25 , 与护栏 成 45度角, 在两个极限位置的中间位置, 长槽 63与护栏 19成 90度角。 众所 周知的, 45度角和 90度角是最经常切割的角度。 而这样的设置使得当工件抵 靠在护栏 19上时, 通过将转臂 50转动到极限位置和中间位置, 可以方便的以 45度角或 90度角切割工件。
转臂 50安装于底座 11后, 枢转轴 35的枢转轴线位于护栏 19的工件抵靠 面和转臂 50的长槽 63的交线上。
底座 11的高台面 15上, 枢转轴 35的上方还设有一个扇形槽 23 , 扇形槽 23位于导轨 80上的切割槽 89的下方, 保证转臂 50旋转的任意角度, 手持式 切割机 1的工作头 3均不会切割到底座 11 , 而只会落到扇形槽 23中。
工作台 10还包括设于底座 11和转臂 50之间的指示装置 100 , 该指示装置 100用于指示手持式切割机 1的切割轨迹和第一支撑平面 51上护栏 19的垂线 之间的夹角。 这个夹角等于转臂 50和底座 11之间的夹角减 90度。 如图 2 , 转 臂 50上弧形配接部 53的一侧还设有一个和枢转孔 61和长槽 63连通的指针安 装槽 67 , 指针安装槽 67和长槽 63同向, 一直延伸到转臂 50的末端, 将弧形 配接部 53断为两个部分。 指针安装槽 67和枢转孔 61 内安装一个定位件 101, 定位件 101 包括弧形的定位部 107和从弧形的定位部 107的中间点向该弧形的 圆心延伸的连接部 103, 连接部 103的末端为一个圆环 105, 圆环 105安放在枢 转孔 61中, 连接部 103的主体安装在指针安装槽 67中, 定位部 107延伸出指 针安装槽 67外, 靠着弧形配接部 53和转盘 65。 连接部 103上通过螺柱螺孔结 构安装有一个指针座 111, 指针座 111的主体从弧形配接部 53的断口中向上延 伸到弧形配接部 53的顶部, 其上安装有一个指针 113。 指针座 111和弧形配接 部 53容纳于设置在底座 11的高台面 15上的弧形通槽 21 中, 和角度限位壁 25 类似的, 弧形通槽 21的两个末端限制弧形配接部 53的移动范围, 使转臂 50 的长槽 63在相对于前述的护栏 19垂线正负 45度的角度范围内转动。由于本实 施例的长槽 63并非位于转臂 50的中轴线上, 而是偏向一侧, 所以弧形配接部 53的断口也不位于弧形配接部 53的中心位置而是偏向一侧, 所以为了使指针 113对称的指示正负 45度的范围, 弧形通槽 21的轴心虽位于枢转轴 35上, 但 弧形通槽 21相对于穿过枢转轴 35的垂直于护栏 19的工件 4&靠面的轴线不对称 的设置, 以使得弧形配接部 53的两端分别抵靠弧形通槽 21的两端时, 长槽 63 和护栏 19的夹角分别为正负 45度。 弧形通槽 21的外边缘, 即高台面 15的拱 形部上表面上设有角度指示盘 27, 其上标有指示角度的刻度值。 指针 113略高 于弧形通槽 21, 指示角度指示盘 27上的角度刻度值。 由于指针 113位于转臂 50的长槽 63的纵向轴线, 也就是导轨 80的切割槽 89的纵向轴线上, 因此指 针 113指示的角度刻度值就是手持式切割工 1具的切割轨迹和护栏 19垂直线之 间的夹角, 该角度介于正负 45度之间。 角度指示盘 27上的角度刻度值可以有 多种设置方式, 喷漆, 贴标帖或与底座一体成型均是可行的。
一套相配的螺栓 39、 螺母 41, 垫片 43和旋钮 45通过转臂 50上的枢转孔 61和定位件 101上的圆环 105, 将转臂 50和定位件 101轴向固定于底座 11。 其配合形式为业界人员所习知的, 在此不再赘述。
定位件 101 的定位部 107 中设有弧形的定位槽 109, 一个定位螺栓 115 穿 过定位槽 109和设于底座 11上高台 15上的通孔 33,和一个定位螺母 117配接, 定位螺母 117安装于定位锁钮 118并可被其带动旋转。 通过定位锁钮 118带动 定位螺母 117 进行松紧调节, 可以选择性的锁定定位件 101, 禁止定位件 101 相对于底座 11的枢转轴 35枢转, 进而锁定转臂 50和底座 11的夹角; 或松开 定位件 101, 允许定位件 101相对于底座 11 的枢转轴 35枢转, 进而可自由调 节转臂 50和底座 11之间的夹角。 相应的, 也就是锁定或调节手持式切割机 1 的切割轨迹和护栏 19垂线之间的夹角。
参见图 3至图 5,工作台 10还包括模块化的辅助支撑臂 130和延长臂 140, 它们通过规格统一的燕尾槽 29 和燕尾块 31 相互连接在一起, 扩大工作台 10 对工件的支撑范围。
如图 3和图 4,辅助支撑臂 130垂直于护栏 19安装,其一端具有燕尾块 31, 燕尾块 31可连接到底座 11纵长方向上转臂 50—侧的侧壁上垂直于第一支撑平 面 17延伸的燕尾槽 29。 连接到底座 11 的辅助支撑臂 130垂直于护栏 19并与 转臂 50间隔开,辅助支撑臂 130具有一个安装座 131,上面可以安装支撑件 133, 具体为标准规格的木条,安装好的木条的上表面和第一支撑平面 17和第二支撑 平面 51平齐, 以协助第一支撑平面 17和第二支撑平面 51支撑工件。 标准规格 的木条是容易获得且廉价的, 使用木条而非一体成型的辅助支撑臂 130使得辅 助支撑臂 130整体更加便宜和耐用, 当木条被切割到损坏到无法继续使用, 只 需简单的更换木条, 而不必丢弃整个辅助支撑臂 130。
优选的, 安装座 131可以制造为可沿自身的纵向轴线伸縮的结构, 以安装 不同长度的木条, 适应不同的工件加工需要。
工作台 10上具有多个安装辅助支撑臂 130 的燕尾槽 31, 辅助支撑臂 130 的数量也可以是多个, 通过辅助支撑臂 130的安装位置和数量的组合, 可以形 成多种不同的工件支撑方式, 满足不同加工需求。
如图 5, 延长臂 140沿底座 11的纵向轴线安装, 即其自身的纵向轴线和底 座 11 的纵向轴线平行或共线。 延长臂 140的一端设有燕尾槽 31, —端设有燕 尾块 29, 底座 11的纵长方向上的一端设有燕尾槽 31, 另一端设有燕尾块 29。 这样的设置使得多个延长臂 140和底座 11可以自由的首尾依次连接, 即, 使用 者可以根据情况在底座 11的两端分别安装延长臂 140, 以切割较长的工件的中 间部分, 也可以在底座 11的一端依次安装多个延长臂 140, 以切割较长的工件 的边部。 和底座 11类似, 延长臂 140呈台阶状, 具有高台面, 低台面, 低台面 的表面形成支撑工件的辅助支撑平面 141, 高台面和低台面之间的阶梯形成供 工件抵靠的护栏 143, 延长臂 140安装于底座 11后护栏 143和护栏 19平齐, 形成更长的工件抵靠面。 延长臂 140的低台面一侧的侧壁上同样设有多个燕尾 槽 31, 以垂直于护栏 19的安装辅助支撑臂 130。
使用者可以根据需求, 使用延长臂 140和辅助支撑臂 130灵活的组装自己 需要的工作台 10, 以支撑各种工件。
参照图 6至图 9, 工作台 10还包括用于切割工件形成斜坡面的斜切支撑臂
150。
如图 6、 图 7, 斜切支撑臂 150由作为主体的斜切座和安装在斜切座上的斜 导轨 157组成。斜切座沿自身纵长方向延伸,包括沿纵长方向延伸的支撑部 151, 支撑部 151上表面形成和前述的第一支撑平面 17和第二支撑平面 51平齐的上 表面 153; 以及沿纵长方向延伸、 邻接支撑部 151 的斜坡部 155, 斜坡部 155 上安装有与上表面 153成 45度夹角的斜导轨 157。斜导轨 157的结构和导轨 80 类似, 其上设有供工作头 3通过的斜切槽 165、 与上表面成 45度角的导向手持 式切割机 1 的导向平面、 引导手持式切割机 1 滑动的两个侧挡板 163、 位于斜 导轨 157两端的止挡块等。其中斜切槽 165位于上表面 153的上方。斜坡部 155 的较高的一侧边高于上表面 153, 且斜坡部 155和上表面 153之间的阶梯连接 部形成中间断开的护栏 161, 护栏 161 的表面形成工件斜切抵靠面。 护栏 161 中间断开部分允许待加工的工件的端部伸入到斜坡部 155 下供手持式切割机 1 加工, 将端部切割出 45度角的斜面。
如图 7、 图 8, 为了精确的加工工件, 从工件端部的顶角处切割进入工件, 斜切支撑臂 150上设有校准装置 180。校准装置 180包括一个止挡座 183, 止挡 座 183的主体呈片状, 一侧具有垂直于主体向下延伸的安装部 185, 安装部 185 上设有安装孔 187,与斜导轨 157相对的第一侧壁 167上设有对应的安装孔 168, 相配的校准螺柱 189和校准螺母 191 穿过安装孔 187和安装孔 168, 将止挡座 183安装在斜切支撑臂 150 内部。且校准螺柱 189上、止挡座 183的安装部 185 和第一侧壁 167 的内侧之间设有一弹性件, 具体为弹簧 195, 弹簧 195—端抵 靠在止挡座 183的安装部 185上, 一端抵靠在斜切座的第一侧壁的内表面。 弹 簧 195推动止挡座 183沿校准螺柱 189的轴向方向, 也就是垂直于护栏 161平 面的方向远离第一侧壁 167。带动安装好的止挡座 183的主体平行于上表面 153。 止挡座 183 的另一侧设有两个垂直于主体向上延伸的止挡块 181, 止挡块 181 向上延伸到高于上表面 153 的位置, 垂直于上表面 153, 以限制工件端部伸入 斜坡部 155下的长度。 两个止挡块 181各自具有一个止挡面, 两个止挡面共面、 间隔设置且平行于护栏 161平面。 间隔设置可以使两个止挡面分别止挡工件的 端部的两侧, 更加稳定。 第一侧壁 167外的校准螺母 191上套有一个调节旋钮 193,调节旋钮 193可以旋转带动校准螺柱 189在垂直于护栏 167的方向上前后 移动, 进而带动止挡座 183和其上的止挡块 181克服弹簧 195的力沿靠近第一 侧壁 167 的方向移动; 或松开止挡座 183, 由弹簧 195推动止挡座 183和其上 的止挡块 181沿远离第一侧壁 167的方向移动。 止挡座 183的主体上还安装有 指针 197, 斜切支撑臂 150 的上表面 153上设有对应的刻度槽 154, 指针 197 跟随止挡座 183移动, 指示刻度槽上 154的不同刻度, 以供操作者读取止挡块 181的位置或其他与止挡块 181的位置相关的物理量。
通过上述的方式, 操作者可以方便并准确的调节止挡块 181在垂直于护栏 167 的方向上的位置。 并通过准确调节止挡块 181 的位置精确的切割不同厚度 的工件的顶角。 参见图 8, 首先, 斜导轨 157和斜导轨 157上的斜切槽 165 的 位置是固定的, 斜导轨 157倾斜 45度设置, 所以工作头 3在 45度的切入角上 的轨迹是固定的,在该固定轨迹与斜切座的相交处,设有倾斜 45度角向斜切座 内侧凹陷、 具有设定好的深度的工作头收容槽, 以使得工作头切断工件后落到 该工作头收容槽内, 不会切割到斜切座。 若要始终切割各种不同厚度的工件的 端部的顶角, 只需移动工件的位置, 使得该顶角位于工作头 3的切割轨迹上。 又因为两个小角为 45度的直角三角形的两垂直边的边长相等,因此当工件顶角 位于工作头 3 切入轨迹, 那么当厚度减少 a, 只需将工件朝靠近第一侧壁 167 的方向上移动同样的距离 a, 就可以保证厚度减少 a后的工件的顶角同样位于 工作头 3的切入轨迹上。 通过上述的原理, 操作者只需根据工件的厚度调节止 挡块 181的位置, 限制工件在垂直于护栏 167的方向上的位置, 即可以方便准 确的切割工件的顶角。 当工件厚度减小 a, 就相应的将止挡块 181 向第一侧壁 167滑动距离 a。优选的, 直接在前述的刻度槽 154上标示出和止挡块 181的位 置对应的工件的厚度, 即可以达到直观的根据工件厚度选择止挡块 181位置, 保证工作头 3切割工件的端部的顶角的目的。
由于底座 11的纵向上的首尾两端分别设一个燕尾槽 31和一个燕尾块 29, 因此, 斜切支撑臂 150的第一侧壁 167上设有一个燕尾槽 31和一个燕尾块 29, 这样, 斜切支撑臂 150的第一侧壁 167上通过相配的燕尾槽 31燕尾块 29和底 座 11的纵向方向上的两端连接, 并保证斜切支撑臂 150的主体向转臂 50所在 的一侧垂直于护栏 19 延伸, 由转臂 50 的第二支撑平面 51 和斜切支撑臂 150 的上表面 153共同支撑工件。 如图 6和图 9, 斜切支撑臂 150位于底座 11的右 侧和左侧,斜切支撑臂 150的主体均向转臂 50所在的一侧垂直于护栏 19延伸。
斜切支撑臂 150 的主体的纵长方向上的两端具有两个第二側壁 169。 靠近 第一側壁 167 的燕尾槽 31 的第二侧壁 169上设有一个燕尾槽 31, 靠近第一侧 167壁的燕尾块 29的一侧设有一个燕尾块 29。这样斜切支撑臂 150除了可以作 为切工件端部斜面的斜切支撑臂 150使用, 也可以作为一个延长臂使用, 其使 用方式及组合方式和普通延长臂 140—样,将第二侧壁 169上的燕尾槽 31或燕 尾块 29和底座 11的纵长方向的端部的燕尾块 29或燕尾槽 31连接即可, 在此 不再赘述。
参见图 10、 图 11, 工作台 10还包括定宽调节装置 200。
底座 11的高台面 15上靠近护栏 19的位置纵向间隔设有两个定宽尺槽 201, 定宽尺槽 201是一个垂直于护栏 19方向延伸的通孔。两个定宽尺槽 201 内分别 设有一个定宽尺 202, 定宽尺 202垂直于护栏 19延伸。 定宽尺 202的一端具有 作为抵靠部的尺头 203 , 尺头 203 为一个球形端, 然而圆柱形端或其他适于滑 动的端部均是可行的。 尺头 203和定宽尺 202的主体部分之间通过切口隔开。 导轨 80 的一侧具有两个垂直于第一支撑平面 17设置的的竖槽 207。 竖槽 207 为和抵靠部相配的配合部。 竖槽 207可视为为一个球形凹槽, 也可视为一个沿 垂直于第一支撑平面的方向设置的、 供尺头 203滑动的滑轨。 两个定宽尺 202 的尺头 203可以分别安装在相对应的竖槽 207中,竖槽 207的开口和定宽尺 202 的切口相配,使得尺头 203和竖槽 207可相对上下移动,但不能直接轴向脱开, 即定宽尺 202的抵靠部和导轨 80的配合部相配的连接, 使得导轨 80在定宽尺 202的釉向滑动的方向上固定。这样的设置方式使得导轨 80可相对于定宽尺 202 上下移动以切割不同厚度的工件。 工件可由安装于底座 11 的辅助支撑臂 130 辅助支撑。 这样,操作者可以松开定宽尺锁钮 205沿垂直于护栏 19方向前后移 动定宽尺 202并带动导轨 80移动, 以选择导轨 80的切割槽 89距离护栏 19的 距离, 进而选择切割宽度, 选择后锁紧定宽尺锁钮 205后即可稳定的进行定宽 切割。
参照图 11, 定宽调节装置 200进一步包括固定装置, 即定宽尺锁钮 205、 定宽尺套 209、 螺母 215和螺柱 219。 固定装置将定宽尺 202可选的固定在定宽 尺槽 201 中。 定宽尺套 209具有两个平行的 D形环 211, 两个 D形环 211之间 通过带有螺孔的连接片 213连接, 定宽尺 202穿过 D形环 211 中间的定宽尺穿 孔、 和 D形环 211—起安放在定宽尺槽 201 中, 定宽尺 202和连接片 213之间 装有螺柱 219, 螺柱 219 穿过定宽尺槽 201 的上表面的安装孔与带有螺母 215 结构的定宽尺锁钮 205 配接。 定宽尺槽 201 的上方向上凸起形成凸台 217, 定 宽尺锁钮 205可以旋转以带动螺柱 219、定宽尺套 209、和定宽尺 202—起上下 移动。 向上移动时, 定宽尺套 209的连接片 213和部分 D形环 211可以容纳于 凸台 217 内部的收容槽中, 而定宽尺 202 由于长度大于凸台 217的长度, 会抵 靠在凸台 217的底面边缘、 或者说定宽尺槽的端壁上, 被夹紧而锁定; 向下移 动时, 定宽尺 202可被松开以允许定宽尺 202前后移动调节切割宽度。
通过上述的结构, 在需要定宽切割工件时, 第一, 取下转臂 50, 将两个或 更多的辅助支撑臂 130间隔的安装于底座 11的第一支撑平面 17—侧; 第二, 将待切割的工件安放在第一支撑平面 17和辅助支撑臂 130组成的支撑平面上; 第三,将导轨 8G的两个竖槽 207分别配接于两个定宽尺 202的尺头 203;第四, 松开定宽尺锁钮 205, 沿垂直于护栏 19的工件抵靠面的方向滑动导轨 80, 观察 定宽尺 202的刻度值使导轨 80定位到切割预设宽度的位置; 第五, 锁紧定宽尺 锁钮 205, 固定导轨 80位置; 第六, 使用手持式切割机 1 沿导轨 80的导向平 面 81滑动切割工件, 直至切割工作完成。
在不使用定宽调节装置 200时, 只需将定宽尺 202在定宽齿槽 201 中朝远 离护栏 19的方向移动到极限位置。在该极限位置定宽尺 202的尺头 203顶端与 护栏 19表面平齐或深入到护栏 19的后方, 以避免凸出于护栏 9表面, 干扰工 件抵靠于护栏 19。
可选的, 定宽尺 202也可以和导轨 80—体设置, 不使用定宽功能时与导轨 80—起抽出定宽尺槽 201即可, 结构更加简单。
