The invention discloses an automatic overturning gear shifting device which comprises a lower fixing base, an upper fixing base, a lower reset machine, a gear ratchet wheel, an upper separating machine, a limiting ratchet wheel, a deflection cam, a reset machine and a main shaft adjusting component. The center of the lower fixing base is fixedly connected with the lower reset machine, and the center of the lower fixing base is rotationally connected with the upper fixing base; a protruding gear ratchet wheel integrally connected with the lower fixing seat is arranged at the position, connected with the lower resetting machine, of the lower fixing seat, a deflection cam and a limiting ratchet wheel are rotationally connected to the side face of the upper fixing seat, the head of the limiting ratchet wheel is connected with the resetting machine in an inserted mode, and a protruding upper separating machine is arranged on the edge of the gear ratchet wheel. When the reset machine makes contact with the lower reset machine, the lower reset machine pushes the reset machine to move inwards, the deflection cam achieves deflection, at the moment, the limiting ratchet wheel reaches the working position, the upper fixing base rotates reversely and is locked, then the upper fixing base rotates clockwise, and gear shifting work starts. And overturning and gear shifting of the table plate are realized. The device is convenient and practical.
本发明公开了一种自动翻转调档器,包括下固定座、上固定座、下复位机、档位棘轮、上分离机、限位棘轮、偏转凸轮、复位机、主轴调节部件,所述下固定座的中心固定连接下复位机,所述下固定座的中心旋转连接上固定座,所述下固定座连接下复位机的位置为与下固定座一体连接的凸起的档位棘轮,所述上固定座的侧面旋转连接偏转凸轮、限位棘轮,所述限位棘轮头部插接连接复位机,所述档位棘轮边缘设置有凸起的上分离机。复位机与下复位机接触时,下复位机推动复位机向内运动,偏转凸轮实现偏转,此时限位棘轮达到工作位置,上固定座逆向旋转锁定,之后上固定座顺时定旋转、换档工作开始。实现对桌板的翻转和换档。具有方便实用的特点。
