[0002] After an automatic feeding device is added to an automatic machine tool or a semi-automatic machine tool, the processing cycle can be continuously and automatically carried out, turning it into an automatic machine tool. The loading and unloading device of the machine tool is used for semi-automatic machine tools with high efficiency, short machine operation time, and frequent workpiece loading and unloading, which can significantly improve production efficiency and reduce physical labor. The loading and unloading device of the machine tool is also an essential auxiliary device for forming an automatic production line. However, when the automatic machine tool is loading and unloading materials, there will be a phenomenon of material clamping due to unstable materials.

[0003] At present, when most automatic machine tools on the market encounter the phenomenon of material clamping during production, manual labor is required to reach into the mechanical working area to remove the clamped material, which not only wastes a large amount of production time but also poses certain safety hazards, bringing inconvenience to normal production.

[0006] Preferably, the base includes a base plate, two limit blocks and a baffle plate. The top of the base plate is respectively fixedly connected to the bottoms of the two limit blocks, and the two limit blocks are symmetrically distributed about the center of the base plate.

A feeding through hole is provided in the middle of the feeding bottom plate, and the outer wall of the feeding through hole is movably sleeved with the outer wall of the lifting top plate.

[0011] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0012] In the present utility model, when the device jams the material, when the next workpiece is fed, it pushes the feeding bottom plate to move linearly. The linear movement of the feeding bottom plate drives the lifting top plate to move linearly. The linear movement of the lifting top plate drives the lifting threaded rod to move linearly.
