Deep hole drilling machine capable of automatically replacing gun drill and control method

Abstract

The invention discloses a deep hole drilling machine capable of automatically replacing a gun drill. The deep hole drilling machine comprises a machine tool, a sliding plate arranged on the machine tool, and a replacing device. Sliding plate guide rails are arranged on the sliding plate. A front guide box, a supporting frame and a spindle box are sequentially and slidably arranged on each sliding plate guide rail from left to right. The replacing device is arranged beside the machine tool and comprises a base, a sliding seat, a guide rail, a lead screw, a mechanical arm and a gun drill clamping mechanism, the sliding seat is slidably connected with the base through the guide rail; the lead screw drives the sliding seat to move along the guide rail through a motor; the mechanical arm is arranged on the sliding seat; and the gun drill clamping mechanism is arranged on the mechanical arm and used for clamping the gun drill. A drill bit of the gun drill can be replaced automatically on the deep hole drilling machine, the problem that a long gun drill is difficult to replace is solved, the current situation that a drill bit of a gun drill of an existing machine tool is replaced manually is broken through, the Z-axis structure mode of an existing deep hole drilling machine is broken through, and a foundation is laid for a deep hole machining center and an automatic deep hole machining machine tool.

Description

Technical field [0001] The invention relates to the field of machine tools, in particular to a deep hole drilling machine capable of automatically changing gun drills. Background technique [0002] In the existing deep hole drilling machine, due to the long length of the gun drill, the longest is generally more than 2 meters, and the rod diameter is very thin, generally the smallest is 3 mm. When replacing it, a guide sleeve and support must be installed on the gun drill. The gun drill is very weak in strength and has no rigidity at this time. It is easy to bend during the mobile installation process, causing damage to the gun drill, and the manual replacement of the gun drill is cumbersome, there are many precautions, and the replacement efficiency is low. ,low quality. [0003] Due to the rapid development of the modern manufacturing industry, manual gun drill replacement is far from meeting the needs of production. Therefore, it is urgent to invent a device that can automatical...

Problems solved by technology

[0002] In the existing deep hole drilling machines, due to the long length of the gun drill, the longest one is generally more than 2 meters, and the diameter of the rod is very thin, generally the smallest is 3 mm. When replacing it, it is necessary to install a guide sleeve on the gun drill to support At this time, the gun drill has poor strength and no rigidity. It is easy to bend during the mobile installation process, causing damage to the gun drill. The manual replacement of the gun drill is cumbersome, with many precautions and low replacement efficiency. ,low quality

[0003] Due to the rapid development of modern manufacturing industry, manual replacement of gun drills is far from meeting the needs of production. Therefore, it is urgent to invent a device that can automatically replace gun drills
