2. Description of the Related Art A long work piece such as a chassis frame of a vehicle, particularly a large vehicle such as a truck, has a length that greatly exceeds the processing range of a processing machine, for example, 6 to 12 times, and is therefore small. It cannot be processed by attaching it to the processing jig once like parts. Therefore, conventionally, for processing the long work piece, a plurality of single-axis drilling machines are arranged along a roller conveyor, and a cutting tool such as a drill is used with a guide bush of a split-type jig attached to the single-axis drilling machine. Drilling was performed while guiding, and after processing, the workpiece was manually fed and conveyed on the roller conveyor.

However, according to the conventional processing method, the split-type jig has to be reassembled each time the type of the work is changed, and the split-type jig has a large work piece. The larger and heavier it is, the more the assembling work is not only a heavy burden on the worker, but also the work efficiency is lowered. Further, it is a difficult task to manually feed a heavy work piece while positioning it on a roller conveyor, and there is a drawback in that the processing accuracy also varies due to operator fatigue.

SUMMARY OF THE INVENTION The present invention has been made to eliminate the above-mentioned drawbacks of the prior art. The purpose of the present invention is to cut a long workpiece with a machining machine such as a machining center. By dividing into multiple processing sections within the processable range and performing processing sequentially for each processing section, it is possible to process all the processing points of the workpiece with one processing machine with a relatively small processing range. There is also a need for a split-type jig, thereby reducing the burden on the workers and reducing the number of workers, thus achieving a significant labor saving.

As described above, according to the present invention, a long work piece is divided into a plurality of processing sections within a range that can be processed by a processing machine such as a machining center, and processing is sequentially performed for each processing section. As a result, processing machine 1 with a relatively small processing range
There is an effect that all parts of the workpiece can be processed by the table, and as a result, the split type jig is unnecessary, the burden on the workers can be reduced and the number of workers can be reduced, which is a great labor saving. There is an effect that can be achieved.

A plurality of positioning devices are arranged in the feed direction of the workpiece, and the positioning devices are sequentially engaged with a positioning jig mounted on the tip of the workpiece conveyed by the chain conveyor for positioning. Since the processing is performed sequentially for each processing section, it is possible to position and process the workpiece with high accuracy regardless of the expansion and contraction of the chain conveyor, and as a result, the processing quality of long workpieces can be obtained. There is an effect that can be improved.
