Description

Technical Field

[0001] The utility model relates to the technical field of machining machine tools, in particular to a turning, milling and drilling integrated machine tool with a replaceable drill bit. Background Art

[0002] A lathe is a machine tool that uses a turning tool to perform turning processing on a rotating workpiece. A milling machine is a machine tool that uses a milling cutter to perform milling processing on a workpiece. It mainly processes planes and grooves through the rotation of the milling cutter, and can also process various curved surfaces, gears, etc.

[0003] For example, a Chinese patent with announcement number CN116787175A discloses a CNC machine tool, including a frame, a spindle, a left-right motion mechanism, an up-and-down motion mechanism, a rotating mechanism and a processing head (equivalent to a drill bit). The spindle is arranged on the frame, and the spindle is used to clamp and fix the workpiece and drive the workpiece to rotate. The axis of rotation of the spindle extends along the left-right direction. The left-and-right motion mechanism is arranged on the frame, and the up-and-down motion mechanism is arranged on the left-and-right motion mechanism. The left-and-right motion mechanism drives the up-and-down motion mechanism to reciprocate along the left-and-right direction. The rotating mechanism is arranged on the up-and-down motion mechanism, and the up-and-down motion mechanism drives the rotating mechanism to reciprocate along the up-and-down direction. The processing head is arranged on the rotating mechanism, and the rotating mechanism drives the processing head to rotate to adjust the direction of the processing head. The rotation axis of the rotating mechanism is arranged along the front-and-back direction, and the processing head is used to process the workpiece.
