Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Application Field) This invention relates to the improvement of a multi-purpose machine, and more specifically, the present invention relates to an improvement of a multi-purpose machine, and more specifically, a plurality of planetary gears each meshing with a fixed sun gear are mounted on a turntable directly connected to a megatorque motor. This rotary compound machine is equipped with a jig unit and rotates the turntable intermittently, so that when the turntable is stopped, multi-face simultaneous machining of a large number of workpieces can be sequentially performed by each processing machine at the station of each jig unit. .

(Conventional technology) In recent years, individualization and diversification have been exemplified by the automobile industry.

The demand for higher performance has reached a major turning point.

Conventionally, for example, a complex processed product with many processes and processing parts was divided into several processes, and the processing parts were divided to the extent that they could be processed simultaneously, and a dedicated machine was used to process each division. , the workpieces are arranged at regular intervals according to the processing order, and the workpieces are placed one at a time when all the processing at each station is completed.
So-called transfer machines that move only the station and clamp it to complete all machining one after another, and the movement and positioning of various parts to process machines such as chamfering, boring, drilling, tapping, etc., are eliminated as much as possible. Complex machine tools that can perform these processes with just one installation have become widely prized for the purpose of streamlining production. (Problem that the invention aims to solve) However, the former transfer machine However, the latter has drawbacks such as increased initial investment during installation, restrictions and inconvenience in changing the design of processed products, increased installation floor space, and increased complexity of failures due to the complexity of the overall function. This also increases the floor space for multi-tasking machine tools.

In addition to the complicated functions, since the machine was specially designed for a specific workpiece, there were drawbacks such as the inability to flexibly deal with changes in the shape and two dimensions of the workpiece. Conventional production equipment machines including these machines also have problems in terms of rationalization of multi-face processing, sharing of processes, consolidation, compounding, and functionality.
