Then, the material bar is loaded into the loading box 2. The lifting cylinder 3 drives the loading box 2 to move up and down, so that the loading box 2 moves downward to the position of the fixture axis and stops. At the same time, the push cylinder 4, together with the push column 5, pushes the material bar inside the loading box 2 into the fixture. Then, the fixture of the CNC machine tool holds the material bar. After that, the push cylinder 4 retracts, and at the same time, the lifting cylinder 3 drives the loading box 2 to move upward. If workers need to process more material bars, a guide rail 6 can be installed. The guide rail 6 is aligned with the feeding port 21.

After the pusher column 5 pushes the material bars inside the feeding box 2 into the clamp, space is freed up inside the feeding box 2. After the feeding box 2 resets, the feeding port 21 is aligned with the guide rail 6. At this time, the material bars inside the guide rail 6 will enter the space inside the feeding box 2 to achieve the purpose of feeding. After installing the guide rail 6, in order to prevent the material bars from being squeezed into the feeding box 2, a baffle can be installed on the inner side of the feeding box 2 above the feeding port 21.

[0047] In summary, compared with the prior art, this application provides an installation plate 1 above the fixture of the data machine tool, on which a feeding box 2 is provided. The lifting cylinder 3 can drive the feeding box 2 to move up and down. During feeding, the lifting cylinder 3 pushes the feeding box 2 down so that the bottom of the feeding box 2 is aligned with the fixture. Then, the push cylinder 4 pushes the material bar into the fixture, which facilitates the fixture to clamp the material bar. This achieves the purpose of automatic feeding and clamping, thereby achieving the purpose of efficient material processing.

[0048] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art.
