Description

Slitting and sliding center turning and milling machine tool with five-axis structure on the positive axis

technical field

The utility model relates to a slitting and sliding type turning and milling machine tool with a positive axis and a five-axis structure.

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 main shaft of the machine tool is a through hole. The tail end of the machine tool main shaft is connected to the feeder. The raw material of the workpiece is placed on the feeder. After the worker edits the program, the feeder Continuously feed materials into the positive spindle of the machine tool in sequence, and the machine tool spindle clamps the bar to move back and forth on the Y-axis, and cooperates with the guide sleeve structure of the machine tool (the guide sleeve can be interchanged with synchronous electric guide sleeves, linkage guide sleeves, etc.) or without The guide sleeve structure 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.

The Y1-axis slide plate in the Y1-axis group in the positive axis structure can be installed with two rows of tools, and the two rows of tools face each other in the X direction. Since the Y1-axis slide plate is a complete part, all the tools move in the X, Y, and Z directions. When it is a synchronous action, the process to be processed can only be processed by the next tool after one tool completes the stroke. This causes the machine tool to have disadvantages in the positive axis of the machine tool when processing the workpiece, and the mutual limitation of the tools leads to the poor optimization of the workpiece forming time, which affects the forming efficiency of the workpiece.
