Apparatus with the multi-stage power shifting means applied to a machine tool
An apparatus with the multi-stage power shifting means applied to a machine tool includes a housing body, a first transmission device and a second transmission device disposed in the housing body, a coupling device connected to the transmission devices and a controller controlling the gear shifting motion of the transmission devices. The controller includes two control units pivotally connected to respective engaging parts of the transmission devices and a driving system capable of moving the control units. When a power is sequentially transmitted from an external power source to the first transmission device, the coupling device, the second transmission device and then to a power transmission mechanism, the controller adjusts the mode of meshing the engaging parts with other correlated elements in the transmission devices to attain different output torque and speed values, the multi-stage shifting effect and the torque multiplying effect without increasing the bulk.
