Description

A heavy-duty turning and milling compound machine tool

technical field

The utility model relates to the technical field of machine tools, in particular to a heavy-duty turning and milling compound machine tool.

Background technique

A milling machine refers to a machine tool that mainly uses a milling cutter to process various surfaces on a workpiece. Usually, the rotation of the milling cutter is the main movement, and the plane movement of the workpiece is the feed movement. The object of the milling machine is fixed at a certain position on the machine tool. The milling cutter is in the fixture Under the clamping of the machine, it can rotate at a high speed. When it touches the workpiece, it can process planes and grooves on its surface, and can also process various curved surfaces and gears. A lathe is a machine tool that mainly uses a turning tool to turn a rotating workpiece. Generally, the turning tool is fixed at a certain position on the machine tool, and the workpiece rotates along the axis under the grip of the fixture, and is cut when it is close to the knife edge, so it is mainly suitable for machining shafts, disks, sleeves and other workpieces with rotating surfaces. , is the most widely used type of machine tool in machinery manufacturing and repair factories.

In the current technology, the milling function is generally set on the lathe, but when the workpiece is milled on the lathe, only small parts can be processed, but when the heavy workpiece is turned and milled, it cannot be turned on the lathe. Therefore, the lathes in the prior art have low versatility, and the precision of the workpieces processed by milling on the lathes is not high, which cannot reach the precision of the milling machines, and the clamping is also very inconvenient. Because the lathes are horizontal What’s more, when the workpiece is milled, the workpiece needs to be clamped vertically on the workbench. In this way, the workpiece is easy to loose during processing. If the workpiece is loose, the precision of the processed workpiece will be greatly reduced.
