Description

Technical Field

[0001] The utility model relates to the technical field of numerical control machine tools, in particular to a metal cutting workbench of a numerical control machine tool. Background Art

[0002] CNC machine tool is the abbreviation of digital control machine tool. It is an automated machine tool equipped with a program control system. The control system can logically process programs specified by control codes or other symbolic instructions, decode them, express them in coded numbers, and input them into the CNC device through information carriers. After calculation and processing, the CNC device sends various control signals to control the movement of the machine tool and automatically processes the parts according to the shape and size required by the drawing. The CNC machine tool needs to place the workpiece on the workbench to process the workpiece, and the workbench supports the workpiece.

[0003] For example, the public document with application number 201922101773.X discloses a workbench for CNC machine tools that is convenient for unloading materials. The utility model can conveniently unload materials on the workbench. The operation is simple and no manual picking is required. At the same time, the device can flexibly adjust its own height. However, the workbench of the CNC machine tool is provided with a pushing mechanism at the lower inner side of the workbench. When the upper workpiece is being cut, a large amount of debris will be generated. The debris will fall and accumulate under the inside of the workbench. If it is not cleaned in time, it will not only affect the subsequent workpiece processing accuracy, but also affect the normal operation of the pushing mechanism set on the inside, thereby causing the entire workbench to be unable to be used for normal processing. Manual cleaning is time-consuming and labor-intensive, and the pushing mechanism will occupy a certain space under the workbench, resulting in many gaps under the workbench, which is even more inconvenient to clean the waste chips. That is, the pushing mechanism is not applicable here, but will affect the convenience of cleaning the waste chips on the workbench.

[0004] Therefore, in view of this, the existing structural deficiencies are studied and improved, and a metal cutting workbench for a CNC machine tool is proposed. Utility Model Content
