In the cleaning zone Z _W , an outer surface cleaning nozzle 16,
A cleaning liquid is blown onto the workpiece 9 from 16..., and the outer surface of the workpiece 9 is thoroughly cleaned as the workpiece 9 rotates, and the cleaning liquid is injected into the machining hole of the workpiece 9 from the inner surface nozzles 19, 19... to clean the machining hole. Thereafter, when the rotary body 2 further indexes and rotates and the workpiece 9 comes out of the cleaning zone _ZW , the supply of the cleaning liquid to both nozzles 16, 16, . . . , 19, 19, .

After that, the rotary body 2 further indexes and rotates _, and the workpiece 9 enters the draining/drying zone _ZD , where the outer air blow nozzles 18, 18
Compressed air is blown from ... to the workpiece 9, and the workpiece 9
The outer surface is evenly blown with air due to the rotation. During this time, the article holder 10 is rotated at an angle θ.
Air supply device 3 when positioned at 270 degrees
8 is activated, compressed air is blown into the machining hole of the workpiece 9 from the internal nozzles 19, 19, _. When the drying process is completed, the machine returns to its original set position. Then, the shutter 47 is opened, the clamp member 12 is unclamped, and the washed, drained and dried workpiece 9 is taken out of the casing 1 through the access port 46, and the work is completed.

Therefore, in the above embodiment, the rotating body 2
Since the indexing rotation and the rotation of the article auxiliary jig 10 are driven by a single geared motor 7 with a clutch, the structure of the cleaning apparatus can be simplified.

In addition, since the predetermined rotation angle zones when the rotating body 2 rotates are the cleaning zone _ZW and the draining/drying zone _ZD , the cleaning device is not housed in a vertical plane and becomes elongated, and the space it occupies is eliminated. can be narrowed down as much as possible.

Furthermore, since the cleaning nozzles 16, 16 _, . 1
The cleaning liquid sprayed from 6 is continuously applied to the rotating work 9, and the outer surface of the work 9 is
Cleans evenly and reliably.

Moreover, since the cleaning liquid is injected into the machining hole of the workpiece 9 from the inner surface nozzles 19, 19, . . . , the machining hole can be cleaned well.

(Effects of the Invention) As explained above, according to the present invention, by rotating the rotating body and rotating the article holder using a single drive device, the workpiece is rotated and removed from the cleaning zone within a vertical plane. The workpiece is conveyed circularly to the drying zone, and in between, it is cleaned in the cleaning zone and drained and dried in the draining and drying zone, so the outer surface of the workpiece is thoroughly and reliably cleaned. The structure of the cleaning apparatus can be simplified, and the workpiece can be transported in a vertical plane, so that the space occupied by the cleaning apparatus can be reduced as much as possible.
