Double-end CNC (numerical control) deep hole drilling machine

Abstract

The invention discloses a double-head numerical control deep hole drilling machine, which comprises a workpiece moving module, a gun drill feed module and a bed, the workpiece moving module includes a Y-axis lifting slide table, an X-axis workbench and a workpiece fixture, and a Y-axis lifting slide table The movable setting is on one side of the bed, the X-axis table is movable on the Y-axis lifting slide table, and the workpiece fixture is fixed on the X-axis worktable; the gun drilling feed module includes two parallel guide rails, two The guide rails are arranged on the top of the bed relative to the workpiece fixture. Each guide rail is provided with a guide slide and several support protection sleeves in turn. The gun drilling feed module also includes a spindle fixing seat, which is also connected to a servo motor. , the servo motor can drive the main shaft fixed seat to move along the two guide rails. The double-head numerically controlled deep-hole drilling machine of the present invention has the advantages of high machining efficiency, high rigidity, good stability, convenient use, long service life and wide application range.

Description

technical field [0001] The invention relates to the technical field of deep hole drilling machines, in particular to a double-head numerical control deep hole drilling machine. Background technique [0002] Deep hole drilling machine, which is different from the traditional hole processing method, mainly relies on specific drilling technology (such as gun drilling, BTA drilling, ejector drilling, etc.) Special machine tools for drilling are collectively referred to as deep hole drilling machines. The deep hole drilling machine can obtain precise processing effect through one pass, and the processed hole position is accurate, the dimensional accuracy is good; the straightness and coaxiality are high, and it has high surface finish and repeatability. It can process various forms of deep holes conveniently, and it can also solve various special forms of deep holes, such as cross holes, oblique holes, blind holes and flat bottom blind holes. During the processing, the workpiec...

Problems solved by technology

[0003] However, the existing deep hole drilling machines usually only have one drill bit, which can only process one workpiece at the same time, and the processing efficiency is low; the gun drilling tool is prone to bending during rotation, and the stability is not high; in addition, the drill bit The pressure instability of the high-pressure oil accumulated at the backlog will lead to the instability of the processing state. After the drill bit is broken, the operator cannot find it immediately, which will cause unnecessary losses.
