Description

Six-axis rotary milling machine tool

technical field

Background technique

In the existing centering machine market, there has been research on the technology of machine tool motion axes, and the most widely used is the three-axis centering machine with positive axis structure consisting of X1 axis group, Y1 axis group, and Z1 axis group. The Z1-axis slide plate of the three-axis centering machine has a machine tool main shaft. The machine tool main shaft is a through hole. The tail end of the machine tool main shaft is connected to the feeder. The workpiece material is placed on the feeder. After the worker edits the program, the feeder Continuously and uninterruptedly feed the material into the main spindle of the machine tool in sequence. The positive spindle of the machine tool clamps the bar and moves back and forth on the Z axis, and cooperates with the guide sleeve structure of the machine tool (the guide sleeve can be interchanged with the synchronous electric guide sleeve and the linkage guide sleeve, etc.) or The structure without guide sleeve cooperates with the knife row on the slide plate of the Y1 axis group to realize the processing and shaping of the workpiece. If the workpiece is too complicated and the three axis groups of the positive axis structure of the machine tool cannot be formed at one time, the Z2 axis group can be added to the sub-axis of the machine tool to cooperate with the three-axis centering machine to form a four-axis centering machine; or add the Z2 axis group and X2 axis Group, cooperate with the three-axis centering machine to form a five-axis centering machine; or add Z2 axis group, X2 axis group, Y2 axis group, and form a six-axis centering machine after cooperating with the three-axis centering machine. After such cooperation, it is convenient for the workpiece to be formed at one time, and the processes such as turning, milling, drilling, tapping, engraving, inclined hole forming, and eccentric hole forming are completed.

However, the tool installation slide plate is the same part, although multiple rows of tools can be installed, and the tools can be replaced at will, but since multiple rows of tools are installed on the same slide plate, the slide plate can only produce work benefits with a single tool on the screw at the same time , that is, multiple rows of tools can only move synchronously, and all the processes of the positive axis can only be carried out step by step.
