本发明由于采用以上技术方案, 使之与现有技术相比, 通过滑块和回转架 相配合的机械转动动作, 使控制的准确性和可靠性都得到了提高。 附图概述
本发明的特征、 性能由以下的实施例及其附图进一步描述。
图 1是根据本发明的一种阀芯控制装置的内部结构侧视图。
图 2是根据本发明的一种阀芯控制装置的内部结构主视图。
图 3是根据本发明的一种阀芯控制装置的部分组件分解图。 本发明的最佳实施方式
请参照图 1所示, 阀门的阀芯 (图未示) 的动作依靠马达 1来驱动, 马达 1 输出的转动经过减速箱齿轮组件 2减速后传递给驱动凸轮 3 (图 2中可见) , 再经 驱动凸轮 3驱动输出凸轮 4作上下运动,亦即图中的轴向运动 A, 以此驱动阀芯在
第一位置(以最大位置为例)和第二位置(以最小位置为例)之间运动。 当阀芯运 动到最大位置时, 需要使马达断开电源来停止转动, 以使阀芯保持在最大位置; 同 样地, 当阀芯运动到最小位置时, 也需要使马达断开电源来停止转动, 以使阀芯保 持在最小位置。为此,本发明的下述实施例即是提供进行上述控制的位置控制装置。
请参照图 2所示, 本发明一个实例的位置控制装置包括一支撑板 10, 其上设 有驱动凸轮 3, 驱动凸轮 3具有圆形的控制轮廓 30, 并且控制轮廓 30中具有至少 一个凹坑 (图 2中示出 2个 31a、 31b) 。 在驱动凸轮 3的下方左右两侧, 各设有 一个通断控制部件,分别是第一通断控制部件 5和第二通断控制部件 6。举例来说, 第一通断控制部件 5是在阀芯运动到最大位置时使马达断开, 第二通断控制部件 6 是在阀芯运动到最小位置时使马达断开。
请结合参照图 3所示, 第一通断控制部件 5包括一第一滑块 51、 一第一压力 弹簧 52、 一第一回转架 53、 一第一金属触片 54、 一第一导电片 55以及一第一导 电弹簧 56。 其中, 第一回转架 53可绕支点 530枢转, 第一回转架 53具有一受力 侧 531和一压力侧 532。第一滑块 51设于该受力侧 531且第一滑块 51与受力侧 531 之间设置第一压力弹簧 52。 此外, 第一滑块 51的圆形触头可在驱动凸轮 3的控制 轮廓 30中滑动并可落入凹坑 31中。 第一金属触片 54的一端设于该压力侧 531, 第一金属触片 54之下通过第一导电弹簧 56连接一接插片 71, 此接插片 71对应于 第一电源端(图未示) 。 而第一金属触片 54的另一端与第一导电片 55相对, 此第 一导电片 55电连接至马达 1的第一电源输入端。
第二通断控制部件 6包括一第二滑块 61、 一第二压力弹簧 62、 一第二回转架
63、一第二金属触片 64、一第二导电片 65以及一第二导电弹簧 66。其结构与第一 通断控制部件 5类似, 在此不再赘述。
另外, 在图 2所示的三个接插片中, 接插片 72是公共接插片, 与马达 1保持 电连接, 接插片 71通电时例如是使马达 (进而驱动凸轮 3 ) 顺时针旋转, 接插片 73通电时例如是使马达 (进而驱动凸轮 3 ) 逆时针旋转。
下面以图 2所示实施例为例说明本发明的控制装置的工作原理。
当第二滑块 61处在驱动凸轮的凹坑 31b中时, 输出凸轮 4使阀芯 (图未示) 处于最小位置, 接插片 71不通电而接插片 73通电, 但是第二金属接触片 64未第 一导电片 65与接触, 马达不转动, 阀芯保持在最小位置。
之后, 使接插片 71通电而接插片 73不通电。 由于第一滑块 51未在控制轮廓 30的任一个凹坑中,其提供的压力通过回转架 53传递到第一金属接触片 54,使之 与第一导电片 55接触。 这样, 马达 1的两个电源输入端分别连接接触片 71和 72, 致使马达顺时针旋转, 直至第一滑块 51落入凹坑 31a中, 驱动凸轮 3带动阀芯运 动至最大位置。 此时第一回转架 53受导电弹簧和压力弹簧弹力回转, 带动第一金 属接触片 54与第一导电片 55分离, 因而马达 1停止转动, 阀芯保持在最大位置。
此后, 使接插片 71不通电而接插片 73通电, 由于第二滑块 61未在控制轮廓 30的任一个凹坑中, 其提供的压力通过第二回转架 63传递到第二金属接触片 64, 使之与第二导电片 65接触。 这样, 马达 1 的两个电源输入端分别连接接触片 72 和 73, 致使马达逆时针旋转, 直至第二滑块 61落入凹坑 31b中, 亦即回到图 2所 示的状态, 如此反复循环。
应当指出的是, 上面的实施例虽然是以具有两个凹坑的控制轮廓并配合特定 的接插片通电控制机制为例进行描述,但这并非作为本发明的限制。本发明的特点 在于对通断控制部件的改进设计以增进准确性和可靠性,在此基础上所作出的任何 控制轮廓或者通断模式的改变, 也应包含在本发明的范围内。 工业应用性
本发明的阀芯位置控制装置通过电源的通断实现位置控制开闭的目的, 同比 现有的产品,本发明通过滑块和回转架相配合的机械转动动作,使响应准确可靠, 滑块的实际行程大于金属触片的有效行程,产生弹力缓冲作用,保证装置的可靠性。
