This invention discloses a pneumatically protected electric chuck structure, comprising a fixed end and a rotating unit. The rotating unit includes a rotating base, an inner ring chamber, and an outer disk. The inner ring chamber is fixed to the rotating base and the outer disk on both sides, respectively. An electric power source assembly is installed in the fixed end, driving the rotating base to rotate on one side of the fixed end. A pneumatic control mechanism is fixed in the fixed end. An actuator is slidably installed in the inner ring chamber, comprising an actuator body and three sets of sliding blocks. The pneumatic control mechanism drives the actuator body to move laterally within the inner ring chamber. The actuator body, through the three sets of sliding blocks, drives three sets of jaw arms to move centered on the front side of the outer disk to clamp materials. This invention effectively utilizes pneumatic protection to improve the safety of electric chuck operation, significantly increases the upper limit of electric chuck rotation speed, and assists in achieving pneumatic emergency stop, effectively protecting the use of the electric power source.
