Description
定位装置和移动定位方法 技术领域 本发明涉及工艺装备领域, 具体而言, 涉及一种定位装置和移动定位方法。 背景技术 目前, 有些工件 (比如定位工装) 需要初次定位, 同时, 在使用过程中需要前后 沿直线移动, 并且, 需要保证工件移位之后可以准确的复位 (即回到初次定位位置)。 一般情况下, 需要使用定位装置使得工件初次定位、 移位以及复位。 现有技术中 的定位装置分为两种: 第一种是在平台上安装有直线导轨, 在工件底面安装有和导轨 适配的结构, 利用定位块使得工件初次定位, 移位时工件沿直线导轨方向移动, 可以 保证移动过程中没有偏离预定轨迹, 同时复位准确。 第二种结构结合参见图 1至图 3, 首先在平台 Γ上安装第一限位件 10'和第二限位件 30', 初次定位时, 利用千斤顶推动 被定位工件 3'贴紧第二限位件 30', 利用千斤顶再推动被定位工件 3'使其同时贴紧第 一限位件 10', 以完成初次定位。 当被定位工件 3'需要移动时, 利用千斤顶推动被定 位工件 3', 并使被定位工件 3'的其中一个侧面贴紧第二限位件 30'即可, 图 3, M'为 被定位工件 3'的移动方向。 第一种结构需在平台上安装导轨, 并在工件底面安装有和导轨适配的结构, 结构 复杂, 成本较高。 第二种结构定位精度差, 初次定位过程中, 利用千斤顶推动被定位工件 3'朝向第 一限位件 10'移动时, 很容易出现偏斜, 这样, 难以保证初次定位位置的准确。 另外, 在被定位工件 3'移位和复位过程中,被定位工件 3'仅其中一个侧面受到第二限位件 30' 的约束, 另一个侧面没有约束, 在移动过程中容易偏离预定轨迹。 发明内容 本发明旨在提供一种定位装置和移动定位方法, 以解决现有技术中定位装置结构 复杂或定位精度差的问题。 为了实现上述目的, 根据本发明的一个方面, 提供了一种定位装置, 包括: 第一 限位件, 设置在平台上, 与被定位工件的第一侧面相对; 第二限位件, 设置在平台上, 与被定位工件的第二侧面相对, 并限定被定位工件的移动方向, 定位装置还包括: 第
三限位件,可拆卸地设置在平台上, 与被定位工件的平行于第二侧面的第三侧面相对, 并限定被定位工件的移动方向; 其中, 第二限位件与第三限位件之间所限定的距离等 于被定位工件的第二侧面和第三侧面之间的距离。 进一步地, 第三限位件为多个, 沿被定位工件的移动方向分布。 进一步地, 第三限位件为两个, 两个第三限位件均呈长方形, 并且, 两个第三限 位件的长边垂直于被定位工件的移动方向。 进一步地, 第三限位件呈长条状, 第三限位件的长度方向沿被定位工件的移动方 向延伸。 进一步地, 第二限位件呈长条状, 第二限位件的长度方向沿被定位工件的移动方 向延伸。 进一步地, 本发明的定位装置还包括: 设置在被定位工件的第三侧面的第一千斤 顶。 进一步地, 还包括: 设置在被定位工件的平行于第一侧面的第四侧面的第二千斤 顶。 进一步地, 第一千斤顶和第二千斤顶均为两个。 根据本发明的另一方面, 提供了一种移动定位方法, 使用上述的定位装置进行被 定位工件的定位, 包括以下步骤: 在平台上设置第一限位件和第二限位件; 将被定位 工件移动至第一预定位置, 使被定位工件的第二侧面与第二限位件贴合; 在平台上安 装第三限位件, 使第三限位件与被定位工件的平行于第二侧面的第三侧面贴合; 将被 定位工件移动至第二预定位置, 使定位工件的第一侧面与第一限位件贴合以完成被定 位工件的定位。 进一步地, 将被定位工件安装至第一预定位置的步骤中进一步包括: 利用设置在 定位工件的第三侧面的第一千斤顶将被定位工件顶至第一预定位置。 进一步地, 将被定位工件安装至第二预定位置的步骤中进一步包括: 利用设置在 定位工件的平行于第一侧面的第四侧面的第二千斤顶将被定位工件顶至第二预定位 置。 进一步地, 第一限位件、 第二限位件和第三限位件的底面及与被定位工件的接触 面均需金加工。
应用本发明的技术方案, 在平台上预设有第一限位件和第二限位件, 将被定位工 件移动至第一预定位置, 此时, 被定位工件的第二侧面与第二限位件贴合, 再安装第 三限位件, 并且, 第二限位件与第三限位件之间所限定的距离等于被定位工件的第二 侧面和第三侧面之间的距离, 再将被定位工件移动至第二预定位置, 使定位工件的第 一侧面与第一限位件贴合, 这时, 完成了被定位工件的初次定位。 当被定位工件使用 过程中需要移动时,可以沿着第二限位件与第三限位件之间所限定的 "轨道 "进行移动, 这样, 保证了被定位工件移动过程中的沿移动方向的中心线重合。 另外, 如果需要将 被定位工件复位 (移动至第二预定位置) 时, 需要沿 "轨道 "移动被定位工件, 直至定 位工件的第一侧面与第一限位件贴合为止。 本发明的技术方案结构简单并且定位精度 高, 从而有效解决现有技术中定位装置结构复杂或定位精度差的问题。 附图说明 构成本申请的一部分的说明书附图用来提供对本发明的进一步理解, 本发明的示 意性实施例及其说明用于解释本发明, 并不构成对本发明的不当限定。 在附图中: 图 1示出了现有技术的定位装置的主视示意图; 图 2示出了图 1中的定位装置的左视示意图; 图 3示出了图 1中的定位装置的俯视示意图; 图 4示出了根据本发明的定位装置的实施例一的主视示意图; 图 5示出了图 4中的实施例一的定位装置的左视示意图; 图 6示出了图 4中的实施例一的定位装置的俯视示意图; 图 7示出了根据本发明的移动定位方法的实施例的第二步骤的操作示意图; 图 8示出了根据本发明的移动定位方法的实施例的第三步骤的操作示意图; 图 9示出了根据本发明的移动定位方法的实施例的第四步骤的操作示意图; 图 10 示出了根据本发明的移动定位方法的实施例的初次定位后再移动的操作示 意图; 以及 图 11示出了根据本发明的定位装置的实施例二的俯视示意图。
具体实施方式 需要说明的是, 在不冲突的情况下, 本申请中的实施例及实施例中的特征可以相 互组合。 下面将参考附图并结合实施例来详细说明本发明。 图 4示出了根据本发明的定位装置的实施例一的主视示意图; 图 5示出了图 4中 的实施例一的定位装置的左视示意图; 图 6示出了图 4中的实施例一的定位装置的俯 视示意图。 结合参见 4至图 6, 从图中可以看出, 实施例一的定位装置包括: 第一限 位件 10、 第二限位件 30和第三限位件 50。 其中, 第一限位件 10设置在平台 1上, 可 以与平台 1固定连接, 比如焊接, 也可以与平台 1可拆卸的连接, 比如利用螺栓连接, 同时, 第一限位件 10与被定位工件 3的第一侧面相对。 第二限位件 30设置在平台 1 上, 可以与平台 1固定连接, 比如焊接, 也可以与平台 1可拆卸的连接, 比如利用螺 栓连接,第二限位件 30与被定位工件 3的第二侧面相对, 并限定被定位工件 3的移动 方向。 第三限位件 50, 可拆卸地设置在平台 1上, 与被定位工件 3的平行于第二侧面 的第三侧面相对, 并限定被定位工件 3的移动方向。 同时, 第二限位件 30与第三限位 件 50之间所限定的距离等于被定位工件 3的第二侧面和第三侧面之间的距离。 这样, 第二限位件与第三限位件之间限定为一个平行的 "轨道", 被定位工件 3的初次定位和 沿 M方向移动均受到该"轨道"的导向, 保证了被定位工件 3移动或复位过程中的沿移 动方向的中心线重合, 从而保证了定位精度。 平台 1是为了方便操作的工作台, 要求其具有一定的平整度。 平台 1可以单独设 置在地面上, 或者, 也可以是预埋至地下, 使平台 1的上平面与地面向平行。 在实施例一中, 第三限位件 50 的结构的实施方式可以有多种, 优选地, 如图 8 所示, 第三限位件 50为多个, 多个第三限位件 50沿被定位工件 3的移动方向分布, 本图中示出了优选的方式: 设置有两个第三限位件 50, 两个第三限位件 50均为长方 形, 同时, 两个第三限位件 50的长边垂直于被定位工件 3的移动方向。此时在保证定 位精度的前提下, 与被定位工件 3之间的摩擦力最小,但本发明的第三限位件 50并不 限于两个。 或者优选地, 第三限位件 50呈长条状, 长条状的第三限位件 50的长度方 向沿被定位工件 3的移动方向延伸, 从而限定被定位工件 3的移动方向。 在实施例一中, 如图 6所示, 优选地, 第二限位件 30呈长条状, 长条状的第二限 位件 30的长度方向沿被定位工件 3的移动方向延伸,从而限定被定位工件 3的移动方 向。 优选地, 在一种优选的实施例中, 定位装置还包括: 设置在被定位工件 3的第三 侧面的第一千斤顶 71, 以及设置在被定位工件 3的平行于第一侧面的第四侧面的第二
千斤顶 73。 优选地, 第一千斤顶 71和第二千斤顶 73均为两个。 第一千斤顶 71和第 二千斤顶 73可以与设置在平台 1上的固定块配合,移动被定位工件 3,第一千斤顶 71 和第二千斤顶 73结构简单并且操作方便。 上述实施例中的千斤顶也可以有其他施力机构代替, 比如, 气动夹紧装置、 液压 夹紧装置或其它施力机构。 在进行被定位工件 3的定位时, 使用了本发明的移动定位方法, 结合参见图 7至 图 10, 从图中可以看出, 具体包括以下步骤: 步骤一: 在平台 1上预先根据被定位工件 3的初次定位位置设置有第一限位件 10 和第二限位件 30 (未图示), 第一限位件 10和第二限位件 30可以焊接在平台 1上, 也可以与平台 1为可拆卸连接。 步骤二:将设置在被定位工件 3的第三侧面的第一千斤顶 71的底部靠住固定块 5, 将被定位工件 3顶至第一预定位置,使被定位工件 3的第二侧面与第二限位件 30贴合, 如图 7所示; 步骤三: 在平台 1上安装第三限位件 50, 使第三限位件 50与被定位工件 3的平 行于第二侧面的第三侧面贴合, 如图 8所示。 步骤四: 将设置在被定位工件 3 的平行于第一侧面的第四侧面的第二千斤顶 73 的底部靠住固定块 7, 将被定位工件 3顶至第二预定位置, 使被定位工件 3的第一侧 面与第一限位件 10贴合以完成被定位工件 3的初次定位,如图 9所示。根据实际需要, 可将被定位工件 3的四周紧固在平台 1上。 为了进一步保证定位精度, 第一限位件 10、 第二限位件 30和第三限位件 50的底 面及与被定位工件 3的接触面均需金加工。 如图 11所示,本发明的定位装置的实施例二的结构与定位装置的实施例一的区别 在于, 在被定位工件 3的第一侧面安装有沿第一侧面向外延伸的两个定位板。 利用实 施例二的定位装置进行被定位工件 3的定位过程中,步骤一至步骤三与实施例一相同, 步骤四的区别在于, 实施例二的定位装置利用两个千斤顶的底部分别靠住固定块 5和 第二限位件 30, 将被定位工件 3顶至第二预定位置, 使被定位工件 3的第一侧面与第 一限位件 10贴合以完成被定位工件 3的初次定位。 当被定位工件 3使用过程中需要移动时, 可以沿着第二限位件 30与第三限位件 50之间所限定的 "轨道 "进行移动, 利用千斤顶将被定位工件 3定至所需位置, 如图 10
所示, 这样, 保证了被定位工件 3移动过程中的沿移动方向的中心线重合。 另外, 如 果需要将被定位工件 3复位 (移动至第二预定位置) 时, 需要沿"轨道"移动被定位工 件 3, 直至定位工件的第一侧面与第一限位件 10贴合为止。 本发明的技术方案结构简 单并且定位精度高,从而有效解决现有技术中定位装置结构复杂或定位精度差的问题。 以上所述仅为本发明的优选实施例而已, 并不用于限制本发明, 对于本领域的技 术人员来说, 本发明可以有各种更改和变化。 凡在本发明的精神和原则之内, 所作的 任何修改、 等同替换、 改进等, 均应包含在本发明的保护范围之内。
