The loading device body includes a support frame, and an outer frame is arranged on the surface of the support frame. A second motor is arranged on the left side of the inner part of the outer frame, and a third motor is arranged on the right side of the inner part of the outer frame. The utility model cooperates with the gripper, cylinder, gear and tooth block. The cylinder drives the gripper to move up and down to realize the work of picking up materials. The third motor drives the gear to rotate, thereby driving the tooth block to move and realize the translation of the raw material. It solves the problem that the CNC machine tool needs to load materials when processing workpieces. Manual loading is not only time-consuming and labor-intensive, but also easy to be installed and offset, resulting in reduced equipment utilization efficiency and reduced practicality, thereby achieving the effect of improving the equipment utilization efficiency and practicality. In the process of realizing the utility model, the inventors found that the prior art had the following problems: 1. The traditional loading device of CNC machine tools cannot adjust the direction of the manipulator. When the manipulator grabs the material, it can only place the workpiece in the specified material grabbing direction and cannot grab the workpiece in other directions, thereby greatly reducing the work efficiency; 2. The traditional loading device of CNC machine tools is mostly a fixed structure, and the distance between the manipulators cannot be adjusted according to the size of the workpiece. When the workpiece size is different, different manipulators need to be replaced to clamp the workpiece, thereby greatly reducing the practicability of the equipment. Utility Model Content
