Novel boring drilling machine
The utility model relates to a kind of boring drilling machine, is specifically related to the novel boring drilling machine that a kind of porous processing is used, and belongs to mechanical skilled worker's technical field.
Desk-top boring drilling machine mainly is to hole processing, and the drilling machine that uses in the enterprise now when on same workpiece, carrying out porous processing, machines through position, hole one by one, and production efficiency is lower like this, and labour cost is than higher.
The utility model content
The purpose of the utility model is to provide a kind of can realize that same workpiece porous processes simultaneously, saves production cost and the time, enhances productivity and simple in structure, easy to operate novel drilling machine.
The technical scheme of the utility model employing is for this reason: comprise the boring drilling machine; Said boring drill press spindle lower end is provided with a gear shift case; Said gear shift case comprises a driving gear shaft and some driven gear shafts that are connected with driving gear shaft; The said driving gear shaft other end is connected with main shaft, and said gear shift case lower end is provided with the drill bit that is connected with driven gear shaft.
The utility model has the advantages that: because the utility model increased gear shift punch-out equipment structure, can realize that same workpiece porous processes simultaneously, practice thrift production cost and time, improve production efficiency, the utility model is simple in structure, easy to operate simultaneously.
