Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to a multi-purpose machine tool capable of performing cutting as well as assembly of workpieces necessary for cutting.

[Technical background of the invention and its problems]

With the recent trend toward FMS (Flexible Manufacturing Systems), machine tools are required to become more versatile, and in order to expand the machining functions of machine tools such as cutting and grinding, the machining spindle has been made into a unit. , a technology has been developed to detachably attach it to a saddle that moves along the column of a machine tool (for example, Japanese Patent Application No. 55-106459,
JP-A-57-114337).

When cutting workpieces, multiple workpieces are combined,
There are cases where this is attached to a machine tool and machining is performed. In such cases, conventionally, the workpieces that had already been machined were removed from the machine tool, the workers assembled them using dowel pins, bolts, etc., and then reinstalled them on the machine tool for machining. . For this reason, operations such as workpiece removal, assembly, and centering after installation on a machine tool are required, which increases processing time and poses a bottleneck in efforts to automate processing.

[Purpose of the invention]

The present invention has been made in consideration of these points,
The object of the present invention is to provide a multi-purpose machine tool that can perform cutting as well as assembling workpieces necessary for cutting.

[Summary of the invention]

The compound machine tool according to the present invention has two or more groups of processing machines arranged adjacently each other, each consisting of a combination of a processing cell to which a workpiece cutting tool and a workpiece assembly tool can be attached, and a workpiece chuck function. However, each processing machine group has a small number of processing cells equipped with a workpiece chuck function (one of which can face one of the other groups).

According to the present invention, each workpiece is processed using a plurality of processing cells in each processing machine group, and -
One of the next processed workpieces is automatically assembled and fixed to the other workpiece, allowing multiple workpieces to be processed together.
