A small CNC milling and drilling machine and its corrected tool setting method

Abstract

The invention provides a small-scale numerically-controlled milling and drilling machine and a correction and tool replacement method thereof. The numerically-controlled milling and drilling machine comprises a correction and tool alignment device, wherein the correction and tool replacement device is arranged on a workbench and a drilling and milling head box and comprises three CCD (Charge Coupled Device) cameras and three laser diastimeters, and the CCD cameras are respectively and fixedly arranged on two ends of a Z-direction sliding table of the workbench and the front surface of a X-direction sliding table of the workbench; the laser diastimeters are respectively and fixedly arranged on the two side plates and a front panel of the drilling and milling head box, and the laser diastimeters are respectively connected with a numerical control computer. The small-scale numerically-controlled milling and drilling machine has the beneficial effects that distance parameters between the laser diastimeters and the tabletop of the workbench are collected and analyzed, the coordinate system of the milling and drilling machine can be timely corrected, and image parameters, which aim at to-be-processed workpieces tools, of the CCD cameras are collected and analyzed, so that the tool alignment precision and the tool alignment efficiency are effectively improved. The small-scale numerically-controlled milling and drilling machine is compact in structure, simple in operation, attractive and generous in appearance, and applicable to enterprises, schools, research institutions and the like.

Description

technical field [0001] The invention relates to the technical field of numerically controlled machine tools, in particular to a small numerically controlled milling and drilling machine and a correction tool setting method thereof. Background technique [0002] CNC milling machine is a machine tool that integrates a digital control system on an ordinary milling machine and can perform milling more accurately under the control of program codes. From the requirements of the development of manufacturing technology, with the emergence of new materials and new processes, and the low cost requirements of market competition, metal cutting is moving towards higher and higher cutting speed and precision, higher and higher production efficiency and system It is becoming more and more reliable, and the structural design and layout of each station is becoming more and more humanized. This requires that the CNC machine tools developed on the basis of traditional machine tools have higher...
