Cradle type machining platform of five-axis linkage numerically-controlled machine tool

The invention relates to a cradle type machining platform of a five-axis linkage numerically-controlled machine tool. The machining platform comprises a rack, an A-axis movement device and a C-axis movement device. The A-axis movement device comprises two A-axis racks, a polishing shaft, a turnover fixed plate and an A-axis stepping motor. The C-axis movement device comprises a C-axis stepping motor, a C-axis motor seat and a rotary disc. A rotary opening is formed in the middle of the turnover fixed plate, the rotary disc is movably arranged in the rotary opening, the C-axis motor seat is fixedly arranged below the turnover fixed plate, the C-axis stepping motor is fixedly arranged on the C-axis motor seat, and the C-axis stepping motor is connected with the rotary disc. According to the technical scheme, the cradle type machining platform has the advantages of being simple in structure, good in stability and fast in movement.
