下面对本实施方式的电动执行器的实现细节进行具体的说明,以下内容仅为方便理解提供的实现细节,并非实施本方案的必须。
请参考图1至图9,为本申请的一些实施例的电动执行器,用于机器人上,尤其是智能机器人如工业机器人、医疗机器人以及仿生机器人等等。该电动执行器包括传动模块10及驱动模块60,驱动模块60包括电机62及电机安装主体61,电机62固定在电机安装主体61内;传动模块10包括传动组件(图未标)及连接传动组件的输出件50;传动组件包括与电机安装主体61固定连接的传动外壳(图未标);输出件50设有中心通孔54以供导线穿过;所述传动外壳上设有连通所述中心通孔54并贯穿至所述电动执行器侧面的第一导线槽。
在一些实施例中,所述驱动模块60还包括连接端子630,所述电机安装主体设有连通所述第一导线槽的第二导线槽610,所述驱动模块60中的连接端子630露出在所述第二导线槽630中。(图5中箭头显示了导线在中心通孔、第一导线槽、第二导线槽的位置)。
在本申请一些实施例中,连接端子630的数量为多个,第二导线槽610包括竖向部分及横向部分,所述连接端子630分别外露在第二导线槽610内;所述第二导线槽610的横向部分连接在若干竖向部分之间,而若干竖向部分分别有所述连接端子630外露于其中。
在本申请一些实施例中,输出件50与电机62同轴设置,因此该电动执行器也称为H型执行器。
请重点参阅图4至图6,传动外壳包括与电机安装主体61固定连接的内齿圈20、与该内齿圈20固定连接的双联齿保持架30及与双联齿保持架30固定连接的输出固定盖40。输出件50包括输出齿圈51、与输出齿圈51固定连接的输出法兰52及与所述输出法兰52固定的输出安装件53。
电机62的输出轴固定的主驱动件70,传动组件还包括一级行星架31、枢接在该一级行星架31上的一级行星齿轮32、与一级行星架31固定连接的二级太阳齿轮33;一级行星齿轮32与主驱动件70及内齿圈20啮合,二级太阳齿轮33与输出件50传动连接。
在本申请一些实施例中,一级行星齿轮32的数量为三个,一级行星齿轮32围绕主驱动件70均匀设置,各一级行星齿轮32同时与主驱动件70及内齿圈20的内齿啮合。在本申请一些实施例中,主驱动件70为齿轮,相当于一级太阳齿轮。
在本申请一些实施例中,一级行星架31通过二级太阳齿轮33枢接在该双联齿保持架30的中心轴上,从而一级行星架31与双联齿保持架30枢接;传动组件还包括至二级行星齿轮34及三级行星齿41;二级行星齿轮34与二级太阳齿轮33啮合;三级行星齿41与二级行星齿轮34固定连接并分别枢接设置在双联齿保持架30的上端与下端;三级行星齿41与输出齿圈51啮合。
在本申请一些实施例中,三级行星齿41与二级行星齿轮34的数量均为四个。三级行星齿41与输出齿圈51的内齿啮合,从而带动输出齿圈51转动。在本申请一些实施例中,各二级行星齿轮34的中部朝向双联齿保持架30延伸有转动轴,各三级行星齿41与对应的二级行星齿轮34的转动轴穿过双联齿保持架30的一端过盈配合。
所述输出法兰52固定于所述输出齿圈51之内。所述输出法兰52枢接在所述输出固定盖40内,所述输出法兰52的中间开设所述中心通孔54。输出齿圈51枢接在输出固定盖40内。

第一导线槽包括设置在双联齿保持架30的第一槽部35及内齿圈20上的第二槽部25;该第一槽部35连通双联齿保持架30的中部及侧壁,所述第一槽部35的一端连通至所述中空通孔54的下端,另一端连通所述第二槽部25。输出齿圈51为空心结构因此有中心通孔54同样延伸到输出齿圈51中心,该中心通孔54连通第一导线槽的第一槽部35。可以理解地,中心通孔54贯穿所述输出齿圈51、输出法兰52、输出安装件53及输出固定盖40。
当主驱动件70转动,利用啮合关系驱使一级行星齿轮32自转,而由于与内齿圈20啮合,一级行星齿轮32在自转的同时也会沿内齿圈20移动,即绕主驱动件70公转,这一公转就带动了一级行星架31转动,从而驱动二级太阳齿轮33转动。二级太阳齿轮33的转动,通过啮合关系驱使二级行星齿轮34自转,由于三级行星齿41与二级行星齿轮34固定连接并分别枢接设置在所述双联齿保持30的上端与下端,从而带动三级行星齿41的自转。而三级行星齿41通过又通过与输出齿圈51的啮合关系实现输出齿圈51转动,从而实现输出齿圈51、输出法兰52、输出安装件53即输出件50的转动。
请参阅图5、图8及图9,所述传动模块10还包括输出轴编码器,所述输出轴编码包括枢接在所述传动外壳上的第一磁铁36以及与所述第一磁铁36相对的第一芯片37,所述第一磁铁36由所述传动组件驱使转动。在本申请一些实施例中,所述输出齿圈51的中心端部外周固定有第一计数齿轮38;所述双联齿保持架30上安装有与所述第一计数齿轮38啮合的第二计数齿轮39;所述第一磁铁36安装在第二计数齿轮39中心,所述第一芯片37安装在双联齿保持架30上。如图8所示,双联齿保持架30呈圆盘状设置,双联齿保持架30的顶部设有环槽301、多个均匀分布的齿轮槽302及位于中部的所述第一槽部35;各齿轮槽302与所述环槽301连通。环槽301用于配合安装所述输出齿圈51,齿轮槽302用于安装所述三级行星齿41。第一槽部35的外端连通至双联齿保持架30的外侧壁,第一槽部35的内端用于安装第二计数齿轮39。
请一并参阅图7,驱动模块60还包括驱动板63,第二导线槽610用于容置连接电机62及驱动板63的导线。在本申请一些实施例中,第二导线槽610分别连通至电机62及驱动板63的连接端子630;即第二导线槽610用于容置分别连接电机62及驱动板63的导线。驱动模块60还包括电机尾盖64及导线盖板65,电机尾盖64安装在电机安装主体61的底部并对驱动板63进行保护。导线盖板65对应安装盖设在第二导线槽610及第一导线槽的部分上。电机尾盖64呈异形结构设置,电机尾盖具有凹陷弧面,以方便与其他执行器对接。
第二导线槽610包括交错连通的竖向部分及横向部分,连接端子分别外露在第二导线槽610内,以供导线连接所述连接端子630后埋设在第二导线槽610中。第二导线槽610的横向部分连接在若干竖向部分之间,而若干竖向部分则分别有连接端子外露于其中。
所述驱动模块60的上端具有开口,所述主驱动件70从所述开口露出。
所述驱动模块60还包括电机轴编码器;电机62包括电机轴620,该电机轴620贯穿电机62。所述电机轴编码器包括固定于所述电机轴620末端的第二磁铁621以及固定于所述驱动板63并与所述第二磁铁621相对的第二芯片;电机轴620靠近传动模块10的一端安装所述主驱动件70,所述电机轴620的另一端固定有所述第二磁铁621并靠近驱动板63设置,以供驱动板63上的第二芯片记录电机轴620转动的圈数。在本申请一些实施例中,电机轴编码器通过记录第二磁铁621转动使磁场改变的次数,从而记录电机62转动的圈数。
驱动模块60还包括安装在电机安装主体61内的抱闸66及抱闸锁定片67,抱闸锁定片67与电机轴620固定连接,通过抱闸66对抱闸锁定片67的作用以限制电机轴620的转动。在本申请一些实施例中,电机轴620穿过电机62及抱闸66后轴体尾部与抱闸锁定片67固定,通过卡簧将抱闸锁定片67轴向限制在抱闸66中。抱闸包括一摩擦片,抱闸锁定片67与摩擦片周向定位实现同步转动或止动。当抱闸66通电时,摩擦片被放开因而电机轴620可以自由转动,当抱闸66断电时,抱闸66内部磁力消失而将摩擦片夹持并施加摩擦力,限制抱闸锁定片67的转动从而限制住电机轴620的转动。
所述电动执行器还包括若干顶丝90,顶丝90连接电机安装主体61与所述内齿圈20,以使电机安装主体61与内齿圈20锁紧。在本申请一些实施例中,电机安装主体61与所述内齿圈20轴向配合,通过顶丝90锁紧,通过拆卸顶丝90,可以快速的更换传动模块10。
本申请电动执行器,通过传动外壳的第一导线槽连通输出件50的中心通孔54及电机安装主体61的第二导线槽610,方便导线可以顺利分别连接电机62、驱动板63及外部的执行器,避免了导线在工作过程中出现缠绕或者破损的问题。而驱动模块60的主驱动件70与传动模块10的传动组件及输出件50的紧密配合,紧凑小巧。
本申请的主驱动件70与一级行星齿轮32啮合,通过一级行星架31传递至二级太阳齿轮33实现减速比为9:1的减速;而二级行星齿轮34带动三级行星齿41转动后,三级行星齿41通过输出齿圈51传递至输出件50的传动比均为4.5:1,因此主驱动件70最终传递至输出件50的减速比为9×4.5=40.5;从而实现了较大的减速,达到柔性执行的需求。
本领域的普通技术人员可以理解,上述各实施方式是实现本申请的具体实施例,而在实际应用中,可以在形式上和细节上对其作各种改变,而不偏离本申请的精神和范围。
