The invention discloses a CNC automatic material loading and taking device, CNC
machining equipment and a working method of the CNC automatic material loading and taking device. The material loading and taking device comprises a material taking mechanism, a clamping mechanism and a
material storage mechanism. The
material storage mechanism comprises a material table and a material disc placed on the material table. The material taking mechanism comprises a mechanical clamping jaw, an X-axis driving part and a Z-axis driving part, the mechanical clamping jaw is fixedly connected with one side of the X-axis driving part, and the other side of the X-axis driving part is fixedly connected with the Z-axis driving part; the clamping mechanism comprises a double-layer
workbench, a pressing plate and a clamping
assembly, the clamping
assembly comprises an X-axis clamping piece and a Z-axis clamping piece, and an L-shaped fixing table matched with a workpiece is arranged on the side face of the pressing plate; a workpiece is clamped between the clamping plane of the X-axis clamping piece and the side face of the L-shaped fixing table and between the clamping plane of the Z-axis clamping piece and the bottom face of the L-shaped fixing table. Automatic material loading and taking can be achieved, manual operation of operators is not needed, the production efficiency is improved, and potential safety hazards in the clamping and taking process are eliminated.
