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 mechanical field, in particular to a method for calibrating the distance between axes of a drilling and gong dual-purpose machine. Background technique [0002] Since circuit board manufacturers need proofing, proofing requires the use of drilling rigs and gong machines for drilling and forming respectively. In order to save time for proofing, a dual-purpose drilling and gong machine that can complete 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 panel installation, disassembly and repositioning, but also save equipment investment. In addition, as the volume of electronic products becomes smaller and smaller, and the circuit board develops in the direction of lightness, thinness, and smallness, the processing precision of the circuit is required to be higher and higher. Due to the complexity of the PCB board materi...
