Linkage transmission device

The invention relates to the technical field of machining devices, in particular to a linkage transmission device. The linkage transmission device comprises a drive motor, a reduction gear, a plurality of spiral transmission mechanisms, actuators and an electric control unit. The drive motor is connected with the reduction gear and provides drive power for the reduction gear. The reduction gear is connected with the spiral transmission mechanisms which can conduct spiral transmission under the drive of the reduction gear. The spiral transmission mechanisms are in serial connection with one another, and each spiral transmission mechanism is provided with one actuator. The electric control unit is used for controlling operation of each actuator. By adoption of the linkage transmission device provided by the invention, multiple working procedures can be conducted at the same time, the machining efficiency can be improved, and waste of manpower resources is reduced. 本发明涉及加工设备的技术领域，具体涉及种联机传动装置，包括：驱动电机、减速机、螺旋传动机构、执
