CNC Machine Tool with High Precision Positioning Function

Abstract

The invention discloses a numerically controlled machine tool with a high-precision positioning function, comprising: a workbench, a positioning fixture is arranged at the top; a lifting device is arranged at the bottom of the workbench; a human-computer interaction interface includes a virtual setting module; a virtual setting module Including: an ultrasonic acquisition module, which collects the size information of the workpiece to be processed through real scene scanning, generates 3D model information, transmits and stores it to the image storage module; a positioning scheme generation module, which generates multiple positioning schemes of the workpiece to be processed; and a coordinate generation module , its coordinate generation module generates the NC program information of the workpiece to be processed according to the 3D model information and the positioning scheme and transmits it to the processor; the present invention provides different positioning schemes according to the different positioning surfaces through the human-computer interaction interface, avoiding artificial selection of positioning The problem of unsatisfactory machining accuracy caused by the surface, and the 3D model information is obtained through the physical object, and the NC program is automatically generated, which not only ensures the machining quality of the workpiece, but also ensures the processing time.

Description

technical field [0001] The invention relates to the technical field of numerical control machine tools, in particular to a numerical control machine tool with a high-precision positioning function. Background technique [0002] CNC machine tool is the abbreviation of Computer numerical control machine tools, which is an automatic machine tool equipped with a program control system. The control system can logically process programs with control codes or other symbolic instructions, decode them, express them in coded numbers, and input them into the numerical control device through the information carrier. After calculation and processing, various control signals are sent by the numerical control device to control the movement of the machine tool, and the parts are automatically processed according to the shape and size required by the drawing. The processing of parts on CNC machine tools mainly depends on the processing program. Unlike ordinary machine tools, it does not nee...

Problems solved by technology

Therefore, CNC machine tools are suitable for occasions where the processed parts are frequently replaced, that is, suitable for single-piece, small-batch production and new product development, thereby shortening the production preparation cycle and saving a lot of process equipment costs. Whether the accuracy can be controlled depends on the selection of the positioning surface, and whether it can achieve high-precision positioning is the key. When workers control the CNC machine tool for processing, they need to manually select the positioning surface for positioning. The selection of the positioning surface is unreasonable.
