Description

Technical Field

[0001] The utility model relates to the technical field of numerical control machine tools, in particular to a feeding mechanism for numerical control machine tool processing. Background Art

[0002] CNC lathe is one of the most widely used CNC machine tools. CNC machine tools automatically process the parts to be processed according to the pre-compiled processing program. We compile the processing route, process parameters, tool movement trajectory, displacement, cutting parameters and auxiliary functions of the parts into a processing program sheet according to the instruction code and program format specified by the CNC machine tool, and then record the contents of this program sheet on the control medium, and then input it into the CNC device of the CNC machine tool to command the machine tool to process parts. During the CNC machine tool processing process, the raw materials need to be transported to the CNC machine tool for processing, and the CNC machine tool feeding device is needed to transport the raw materials;

[0003] A Chinese patent publication (publication number: CN218904509U) discloses a feeding device for a CNC machine tool, which includes a base, a moving groove is arranged on the upper surface of the base, a moving block is slidably connected to the bottom of the moving groove, two fixing rings are arranged above the moving block, a support rod is arranged above the base, a support ring is fixedly connected to the upper end of the support rod, a clamping mechanism for clamping raw materials is arranged on the side of the base, a moving mechanism for moving raw materials is arranged on the side of the moving groove, and a cleaning mechanism for cleaning raw materials is arranged on the upper surface of the base. Through the clamping mechanism, it is beneficial to move the raw materials without using bolts. The raw materials are fixed so that their positions will not shift during transportation. The moving mechanism can automatically transport the raw materials to the inside of the CNC machine tool for processing without manually pushing the raw materials. The cleaning mechanism can clean the dust on the surface of the transported raw materials. However, in actual use, the height of the materials cannot be adjusted according to the height of the CNC machine tool feed port. When materials of different specifications are supported, they cannot be adjusted and fixed. The limitation is high. When the length of the materials is long, there is a lack of support for the materials, and the materials are easily offset, which reduces the feeding effect of the materials. Therefore, a feeding mechanism for CNC machine tool processing is proposed. Utility Model Content
