Digital controlled drill for machining PCBs (Printed Circuit Boards) and tool changing method of digital controlled drill

Abstract

The invention relates to the technical field of PCB machining, in particular to a digital controlled drill for machining PCBs (Printed Circuit Boards) and a tool changing method of the digital controlled drill. The digital controlled drill comprises a base, a workbench, a drill bit assembly and a tool changing assembly, wherein the workbench is movably arranged on the base; the drill bit assemblycan move relative to the workbench; and the tool changing assembly is arranged on one side of the workbench. According to the digital controlled drill disclosed by the invention, one side of a tool apron is provided with a clamping assembly for transferring a drilling tool, the clamping assembly can transfer a new drilling tool from a new tool magazine to one of tool holders along with the tool apron, a drilling tool to be replaced on the tool apron is placed on the other tool holder, and the clamping assembly transfers the replaced drilling tool into a used tool magazine after the tool apronclamps the new drilling tool, so that automatic tool changing is realized; manual operation is not required; and the tool changing efficiency is improved. According to the tool changing method disclosed by the invention, a tool setting operation is performed before and after tool changing, so that the relative position accuracy of the drilling tool relative to the tool apron and / or the workbench is ensured; size error after replacement of the drilling tool is reduced; and the drilling accuracy is improved.

Description

technical field [0001] The invention relates to the technical field of PCB board processing, in particular to a numerical control drilling machine used for processing PCB boards and a tool changing method of the numerical control drilling machine. Background technique [0002] With the development of electronic industry technology, the market has higher and higher requirements for the drilling quality of PCB boards. At present, the drills dedicated to drilling PCB boards have a short service life. In order to ensure the drilling quality, the drills are used continuously for a long time. Afterwards, the tool must be changed, but most of the CNC machine tools on the market currently use manual tool change, the tool change efficiency is slow, and it is difficult to set the tool after the tool change, resulting in large processing errors and reducing the quality of drilling. Contents of the invention [0003] In order to overcome the above-mentioned deficiencies in the prior a...
