Description

The porous boring machine

Technical field

The utility model belongs to the machining equipment technical field, relates to a kind of boring machine of once processing a plurality of holes on workpiece.

Background technology

In the prior art, boring machine is used for processing circular hole at workpiece, only be designed with a main shaft on the common boring machine, when the processing circular hole, to a drill bit be installed in the termination of main shaft first and hole, will change cutter after the boring, carry out bore hole with hole boring cutter, hole of every processing will repeat repeatedly tool changing operation, and operating efficiency is lower.

The utility model content

The utility model is in the prior art, common boring machine is once only processed a hole, when machining hole, need to repeatedly change process tool, affect the problem of production efficiency, a kind of porous boring machine is provided, its technical scheme is: the head of a bed and the tailstock two ends of this porous boring machine lathe bed are installed on the base, be processed with chute at lathe bed, one end mounted motor of the head of a bed, motor connects rotation gearbox and the moving speed-change box of the head of a bed with belt, at tailstock the axle holder is installed, the chute upper end of lathe bed is equipped with travelling table, the side of travelling table is equipped with mobile handwheel and square rotating shaft clutch handle, and the move speed regulation handle is installed on the moving speed-change box, and fixed axis and square rotating shaft are installed on the moving speed-change box, fixed axis and square rotating shaft and workbench are flexibly connected, and end is fixed on the axle holder, rotates on the gearbox rotation speed-regulating hand wheel is installed, and rotates gearbox one side and is rotationally connected head; At chute the hole boring cutter holder is installed, gear-box and fixed mount are installed on the holder, main shaft one end be rotationally connected the head be fixedly connected with, the other end is fixed in the gear-box, be processed with tooth bar on the axle, many group driven shafts are installed in gear-box, be fixed with driven gear on the driven shaft, driven gear meshes with tooth bar respectively, the other end of driven shaft rotates and is fixed on the fixed case, it stretches out on the outer spindle nose end of fixed case installs hole boring cutter, and the center of circle in the axis of hole boring cutter hole to be processed on the workpiece is equipped with work piece positioning on the workbench.

Adopt technical solutions of the utility model, when being processed with the fixation workpiece in a plurality of holes, the hole boring cutter design can be fixed on the home position of circular hole on the workpiece, work together with a plurality of hole boring cutters, disposable a plurality of holes are shaped.
