下面结合附图和具体实施例对本发明的技术方案作进一步地说明:
图 1为本发明的结构示意图。 如图 1所示, 本发明提供一种定子加工设备, 包括定 位夹紧装置 10和冲孔装置 20, 定位夹紧装置 10提供径向涨紧力使套设在其上的定子 100被支撑固定。
图 2为本发明中定位夹紧机构的总成结构示意图。 如图 2所示, 所述的定位夹紧 装置 10包括定位体 12, 定位滑块 13, 定位体 12上至少均匀设有二个通槽 121用来容 纳与之配合的定位滑块 13, 定位体 12的内部设有推力机构斜楔块 15, 推力机构斜楔 块 15提供推力使定位滑块 13在通槽 121 内沿径向向外推动, 定位体 12和定位滑块 13之间还设有回位机构弹簧 14,回位机构弹簧 14提供弹性回縮力使定位体 12和定位 滑块 13处于初始状态。
图 3为定位体的主视图; 图 4为图 3的俯视图; 图 5为图 4的 A-A剖视图。 如图 3、 图 4、 图 5所示, 所述的定位体 12呈圆柱状, 其中部设有空腔 124, 空腔 124的上 部设有台阶孔 123, 定位体 12沿其圆周方向均匀设有四个通槽 121, 定位体 12的下方 连有底座 11, 底座 11与定位体 12焊接后整体加工成形, 底座 11呈方形, 四角处有 倒角, 底座 11的中部设有通孔 111, 通孔 111与定位体 12的空腔 124连通。
作为本发明的优选方案, 由于定子 100内筒壁在通常情况下都是圆柱形的, 所以 将定位体 12设置成圆柱状, 这样方便定子 100的套取, 定位体 12对定子 100的定位 主要依赖于定位体 12上的定位滑块 13产生的推力,所以将定位体 12设置成别的形状 也是可行的。
图 9为斜楔块的主视图, 图 10为图 9的 B-B剖视图, 图 11为斜楔块的立体示意 图。 如图 2并结合图 9、 图 10和图 11所示, 所述的推力机构主要包括设置在定位体 12空腔内的斜楔块 15, 斜楔块 15包括圆柱段 151和圆柱段下方设置的锥台段 152, 圆柱段 151包括大、 小直径段, 小直径段的下部设有锥台段 152, 圆柱段 151 的大、 小直径段与定位体 12空腔内设有的台阶孔 123相配合, 如图 2所示。
作为本发明的优选方案, 将斜楔块 15的上段设置成圆柱段 151, 该圆柱段 151设 置为台阶状, 即分为大、 小直径段, 用大、 小直径段与定位体 12空腔内的台阶孔 123 相配合, 这样斜楔块 15 在动力机构的作用力下, 沿铅垂方向向下运动, 这时圆柱段 151与台阶孔 123相抵靠, 起到一个很好的定位作用。
图 6为定位滑块的结构示意图, 图 7A、 图 7B分别为定位滑块的立体示意图, 图 8为定位滑块的俯视图。 如图 6、 图 7 A、 图 7B、 图 8所示, 定位滑块 13的外表面 133 呈弧形, 与待加工定子 100的内壁弧度相吻合, 定位滑块 13位于定位体 12空腔内的 内表面 132为一斜面, 该斜面 132与斜楔块 15的锥台段 152的斜面相配合, 斜楔块 15在动力机构的作用力下使定位滑块 13在通槽 121内沿径向向外推动。
作为本发明的优选方案, 斜楔块 15的锥台段 152设置为圆锥状, 这是为了方便加 工, 而且与定位滑块 13的斜面 132好配合, 设置成四棱锥等形状也是可行的, 只需保 证锥面与定位滑块 13的斜面相配合即可。
如图 8所示, 定位滑块 13上设有翻边 130, 该翻边 130与定位体 12上的通槽 121 槽口构成定位配合 A, 四个定位滑块 13围成的外直径大于定位体 12本身的外直径。 作为本发明的优选方案,选择在定位滑块 13上设有翻边 130与通槽 121的槽口构成定 位配合 A, 主要也是起到一个定位作用, 当斜楔块 15在撤去载荷时, 弹簧 14在弹力 作用下回縮, 定位滑块 13弹回, 如果没有设置定位滑块 13与通槽 121的定位 A , 定 位滑块 13有可能会沿通槽 121滑落到定位体 12中部的空腔 124中。
定位滑块 13上设有落料孔 131, 落料孔 131 自外向内, 自高向低的斜向布置, 倾 斜角度无严格要求, 方便废料落下即可。 落料孔 131 的出口与定位体 12 的空腔 124 相通, 且出口与斜楔块 15在空腔 124内的位置相避让。
作为本发明的优选方案, 选择将落料孔 131直接设置成自外向内, 自高向低的斜 向布置, 即设置成一个斜向的滑道形式, 这样废料可以方便的进入定位体 12 的空腔 124, 由于定位体 12的空腔 124与底座 11的通孔 111是相连通的, 所以废料再经通孔 111排出, 不会造成废料在定位体 12中的堆积。 落料孔 131 的出口与斜楔块 15在空 腔内的位置相避让,这里斜楔块 15在空腔中的位置主要是指斜楔块在动力机构的作用 力下, 向下运动, 与定位滑块 13的斜面 132相抵靠, 定位滑块 13向外产生推力将待 加工定子 100涨紧时的斜楔块 15的位置, 或是说斜楔块 15的大、 小圆柱段与定位体 12中的台阶孔 123构成定位配合时, 这时斜楔块 15的位置应与落料孔 131处于相避 让的位置, 才可以方便废料的排出。
再如图 3所示, 结合图 2, 所述的回位机构包括弹簧 14, 弹簧 14为开口式弹簧, 整体呈环形, 定位体 12与定位滑块 13相配合的部位分别设有弹簧安装槽 122, 弹簧 安装槽 122的槽深略大于弹簧 14自身的直径, 所述的弹簧安装槽 122沿定位体 12的 周向上、 下设置为二条。
作为本发明的优选方案, 将弹簧 14设置成开口式的环形弹簧, 是为了方便安装, 弹簧 14卡合在弹簧安装槽 122中,定位滑块 13在斜楔块 15的作用力下沿径向向外推 动, 这时弹簧 14产生弹性变形, 当撤去载荷时, 弹簧 14在弹力的作用下回縮, 定位 滑块 13弹回, 保持初始状态。
图 12为冲孔装置的结构示意图, 图 13为图 12的俯视图。 如图 12、 图 13所示, 结合图 1, 所述的冲孔装置 20包括用来容纳底座 11的冲模体 21, 冲模体 21上设有引 导钻头动作的引导套 22, 引导套 22的轴线垂直于定位体 12的外表面, 钻头 23通过 连接件与油缸 24的活塞杆相连。 具体地说就是冲模体 21的中部设有方形通孔, 该方 形通孔为台阶孔 211, 台阶孔 211 的大方形段位于冲模体 21 的下部且与底座 11的外 形相吻合, 用来与底座 11相配合, 防止底座 11在冲模体 21中转动, 底座 11的四角 处设有倒角为工艺倒角; 冲模体 21上还设有引导钻头 23动作的引导套 22, 这样可以 很好地保证钻头 23的运动精度, 从而间接保证了孔的位置精度, 冲出的废料通过定位 滑块 13上的落料孔 131排出。
具体工作过程如下:
图 14为定子 100与定位体和斜楔块的位置关系示意图。 如图 14所示, 先将待加 工定子 100套设在定位体 12上, 此时斜楔块 15在液压油缸 24的驱动下向下运动, 通 过斜楔块 15的锥面 152与定位滑块 13的斜面 132相接触, 促使定位滑块 13在通槽 121内沿径向向外推动, 这时四个定位滑块 13接触待加工定子 100的内壁, 并将其自 定心涨紧, 这时, 钻头 23在液压油缸 24液压力的作用下经冲模体 21冲孔, 冲出的废 料经定位滑块 13上的落料孔 131排出。 当需要取出定子 100时, 撤去斜楔块 15上的 压力, 这时定位滑块 13在弹簧 14的弹力作用下自动回縮, 将定位滑块 13弹回, 从而 松开定子 100, 这时定位滑块 13位于初始状态。
综上所述, 本发明采用定位夹紧机构 10对定子 100实施准确定位, 压紧可靠, 在冲孔时, 在引导套 22的引导下, 可以很好地保证冲头的运动精度, 间接保证了孔的 位置精度, 本发明结构简单, 操作方便, 生产效率高。
