Description

Technical Field

[0001] The utility model relates to a numerical control device, in particular to a precision adjustment numerical control device for numerical control machine tools, belonging to the technical field of numerical control machine tools. 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, and express them in coded numbers. The information is input into the CNC device through the information carrier. After calculation and processing, the CNC device sends out various control signals to control the movement of the machine tool and automatically process parts according to the shape and size required by the drawing. CNC machine tools have better solved the problems of complex, precise, small batch and multi-variety parts processing. They are flexible and high-efficiency automated machine tools.

[0003] A precision adjustment CNC device for a CNC machine tool disclosed in Chinese patent announcement number CN211661148U adopts a second motor to rotate, and the second motor drives the second bevel gear to rotate through the first bevel gear, and the second bevel gear drives the first slider to move through the first threaded shaft, and the first slider drives the clamping plate to fix the workpiece, and adopts a third motor to rotate and drive the second threaded shaft to rotate, and the second threaded shaft rotates to drive the second slider to drive the dust cover to seal and dustproof the machine tool processing table. This scheme can play a good dust-proof role in the processing process, but because it adopts the first slider and clamping plate to clamp and fix the workpiece, it is difficult to achieve stable clamping when processing special-shaped workpieces, thereby affecting the processing of special-shaped workpieces. At the same time, because its dust cover is directly driven by the third motor, in order to ensure the sealing during the contact with the workbench, it will inevitably collide with the workbench. Due to the lack of buffering, the dust cover will be damaged due to long-term use. Utility Model Content
