[Problem that the invention attempts to solve]

However, in conventional equipment, the workpiece cleaning equipment, workpiece indexing equipment, etc. were independent for each cleaning room, and each cleaning room independently indexed and cleaned the workpieces. It has the disadvantage of being relatively complex and expensive, and this tendency becomes more pronounced as the number of cleaning steps increases.

The present invention has been made in view of the above points, and aims to provide an inexpensive cleaning device with a relatively simple configuration.

are simultaneously moved in the X and Y directions to face the machining holes to be cleaned in the workpieces 21 and 21, and cleaning the machining holes with the injection nozzles 5 and 6 are performed alternately to sequentially clean the machining holes on one machining surface. To go. When cleaning of one machining surface is completed, one horizontal support member lifting mechanism 13 lifts the horizontal support member 12 and the support shafts 10, 1.
1. Workpiece 21, via workpiece pallet 9,
21 is lifted up and the support shafts 10 and 11 are collectively rotated by a predetermined rotation angle by one rotational drive mechanism 14, and the workpieces 21 and 21 are placed on the workpiece conveyance line 1 by the lowering movement of the horizontal support material lifting mechanism 13.
The machining hole of the new machining surface thus determined is cleaned by the injection nozzles 5 and 6 as described above. When the workpiece cleaning in each cleaning chamber 7, 8 is completed by alternately indexing the workpiece and cleaning the machined surface of the indexed workpiece, the doors 2, 3, 4 are opened, and the cleaning chamber 7, Workpiece 2 of the previous process is placed in the cleaning position of 8.
1 and 21, and the above-described operation is repeated.
