Description

Technical Field

[0001] The utility model relates to the technical field of machine tools, in particular to a horizontal machine tool propulsion mechanism. Background Art

[0002] A horizontal lathe is mainly a machine tool that uses a turning tool to perform turning processing on a rotating workpiece. Drills, reamers, reamers, taps, dies and knurling tools can also be used on the lathe for corresponding processing. When the horizontal machine tool is processing, a propulsion mechanism is usually used to push the workpiece so as to perform drilling and other processing operations on the workpiece. However, during use, the existing propulsion mechanism has a relatively fixed structure.
