结合图6、7、9所示,所述连动板61沿其侧面向内开设有滑动开口611,该滑动开口611呈U字形,所述连动杆5后端设置有轴体51,该轴体51置于该滑动开口611中,其为开放式装配结构,其装配起来更加方便。
结合图10、11所示,所述外壳1内壁设置有限定所述连动杆5摆动幅度的第一限位块102和第二限位块103,该第一限位块102和第二限位块103之间形成有限定连动杆5摆动幅度的摆幅间隔,该连动杆5置于该摆幅间隔中,以此通过第一限位块102和第二限位块103限定该连动杆5的摆动幅度,即可实现控制输出轴4往返转动的幅度为正10度至负10度。
结合图3、10、11所示,所述外壳1包括有相互卡合固定在一起的左壳体11和右壳体12,该右壳体12前端一体固定有一端盖部13,该左壳体11后端一体固定有一底盖部14,该底盖部14与右壳体12后端对接,该左壳体11还包盖于该端盖部13侧边,所述轴孔101设置于该端盖部13内侧;所述输出轴4穿设于该端盖部13中心。由于右壳体12前端 一体固定有一端盖部13,该左壳体11后端一体固定有一底盖部14,左壳体11和右壳体12相互卡合固定后,组成完整的外壳1,其无需额外装配端盖和底盖,可减少零件,提高装配效率。
结合图10、11所示,所述右壳体12边缘设置有第一沉槽121,并与该第一沉槽121底部设置有卡槽122,所述端盖部13边缘设置有与第一沉槽121连通的第二沉槽131;所述左壳体11边缘安装于该第一沉槽121及第二沉槽131中,且该左壳体11边缘成型的卡缘111与卡槽122卡合固定,以此保证左壳体11和右壳体12装配的稳定性。
综上所述,本发明工作时,马达2启动,并由该马达2的转轴21驱动凸轮3沿一个方向旋转,该凸轮3旋转时通过凸轮轨迹滑槽31驱使该杠杆6以轴孔101为轴心往返转动,且该杠杆6在往返转动的同时通过连动杆5驱使该输出轴4往返转动,达到驱动输出轴4往返转动的目的,其中,该输出轴4往返转动的幅度为正10度至负10度。本发明采用马达2配合凸轮3和杠杆6、连动杆5驱动该输出轴4往返转动,不仅简化了结构,使结构变得更加简单,组装更加方便,并且能够保证运行的稳定性,噪音小;再者,凸轮3是采用其前端设置的凸轮轨迹滑槽31驱使该杠杆6以轴孔101为轴心往返转动,其结构稳定,承载能力强,且该凸轮3与杠杆6在运行过程中不会意外脱离,保证工作质量,该凸轮3旋转一圈时,该杠杆6至少进行两次往返转动,达到变速输出的目的,如需改变输出轴4往返转动的速度,可更换具有不同造型的凸轮轨迹滑槽31的凸轮3,使用起来极为灵活,且方便,可满足不同用户对产品性能的要求。
当然,以上所述仅为本发明的具体实施例而已,并非来限制本发明实施范围,凡依本发明申请专利范围所述构造、特征及原理所做的等效变化或修饰,均应包括于本发明申请专利范围内。
