Abstract

The invention relates to the field of machinery, in particular to a drilling and milling dual-purpose machine and a method for calibrating distances between shafts of the drilling and milling dual-purpose machine. The drilling and milling dual-purpose machine comprises a bed body, a beam arranged on the bed body, a work bench, a drilling shaft, a milling shaft and a vision system, wherein the drilling shaft and the milling shaft are located on a bottom plate; and the vision system is located on the bottom plate. The method for calibrating the distances between the shafts of the drilling and milling dual-purpose machine comprises the following steps of (a) drilling holes on a circuit board by adopting the drilling shaft and the milling shaft of the drilling and milling dual-purpose machine respectively; (b) locating the two holes by using the vision system to obtain machine coordinates of the two holes; and (c) calculating the distances between physical positions, in X and Y coordinate directions, of the milling shaft and the drilling shaft, namely the distances between the two shafts according to machine coordinate values of the two holes. According to the method for calibrating the distances between the shafts, the problem of machining precision caused by deformation due to thermal expansion of a mechanical structure and a workpiece is solved and the machining property of equipment is improved.

Description

Technical field [0001] The invention relates to the field of machinery, in particular to a dual-purpose machine for drilling and gongs and a method for calibrating the distance between shafts. Background technique [0002] Since circuit board manufacturers need proofing, proofing needs to use a drilling machine and a gong machine for drilling and forming. In order to save time for proofing, dual-purpose machines for drilling and forming on the same machine came into being. The use of drilling and gong dual-purpose machines for proofing can not only reduce the time for plate installation, disassembly and repositioning, but also save equipment investment. In addition, as the volume of electronic products is getting smaller and smaller, circuit boards are becoming lighter, thinner, and smaller, requiring higher and higher processing accuracy of circuits. Because PCB board materials and structures, and processing procedures are relatively complicated, the processing process is pron...
