The present invention discloses an machining device based on a portable 5-DOF parallel module. The machining device based on a portable 5-DOF parallel module comprises: a table for moving a parallel module to increase the stroke of the machine tool such that the machine tool can machine large components and can also simultaneously conduct the mounting and the machining of workpieces at different stations; a CNC rotary table; and a portable 5-DOF parallel module. The portable parallel module has a large swing angle range, can conduct the conversion between vertical and horizontal machining modes and can achieve five-face machining in one setup in cooperation with the CNC rotary table. The parallel module can move flexibly, and can machine large and complex components after mounted on the sliding table. After the machining of the workpiece is completed, the parallel module can move to the position of a mounted component through the table to conduct the machining of the next component. Thus, the mounting and the machining of the workpiece are simultaneously conducted at different stations, and the utilization rate and the production efficiency of the portable parallel module are improved.
