The CNC machine tool loading device includes a feeder, the inner wall of the feeder is welded with a groove, the groove is located in the center of the feeder, a blank is placed inside the groove, the outer walls on both sides of the groove are respectively welded with slopes, the outer wall at the top of the slope is welded with a protective cover, the top of the protective cover is fixed with a mechanical arm by bolts, and the outer wall at the top of the mechanical arm is welded with a clip, the fixing mechanism includes a fixed plate, a second telescopic rod and a second motor, the second induction device is fixed to the outer wall of one side of the fixed plate by screws, the second telescopic rod is welded to the outer wall of one side of the fixed plate, the second telescopic rod is connected to the output end of the second motor by a coupling, and the second motor is fixed to the inner wall of one side of the feeder by screws. The utility model can autonomously feed the feeder by setting a material placement table to place the blank and the mechanical arm, and no manual material change is required.

[0004] However, the device often lacks the function of adjusting the angle of the clamping structure. When in use, the clamping structure cannot move within a certain range of angles, and cannot adjust the angle according to actual conditions to clamp materials placed in different positions. It is necessary to additionally install a structure that can correspond to the needs to complete the loading process, resulting in the inability to adjust the clamping structure to adapt to the requirements of clamping operations at different angles, and the inability to ensure work efficiency. Not only that, the device also lacks the function of quick installation and disassembly. When in use, the parts of the loading device that operates for a long time are prone to damage, and the required materials cannot be clamped and moved, resulting in the inability to quickly maintain the damaged structure, the loading process is interrupted, and the entire device needs to be replaced to maintain operation. The operation reliability of the device is not high, and the maintenance cost is increased. Utility Model Content
