Description

Compact actuating mechanism of square sword tower

Technical Field

The invention relates to the technical field of numerical control machine tools, in particular to a compact driving mechanism of a square turret.

Background

The traditional machine tool can only finish one or a certain type of machining, such as turning by a lathe, milling by a milling machine and the like, and some machining, even rough machining and finish machining, can be finished on different machine tools respectively. In order to reduce the auxiliary time and improve the processing precision and efficiency, the development trend of the process and function compound of the numerical control machine tool is increasingly obvious, and novel machine tools for multi-process and multifunctional compound processing are continuously emerging. Among them, the development of the turning center is the most prominent, and it can not only finish the turning of the excircle and the end face. For example, two main shafts capable of rotating synchronously are oppositely arranged on the same axis of a machine tool, and a second tool turret is added, so that multi-tool simultaneous machining can be performed without stopping the machine and clamping a workpiece again, such as front and back continuous machining, plane milling, center hole drilling, side groove opening, inclined hole and inclined plane machining at any angle and the like.

Since numerically controlled machine tools are developed in a direction of smaller size and more functions, first, the driving mechanism must be more compact, smaller, and more stable.
