The nozzle is rotated at high speed, and the rotating nozzle is gradually moved along the surface of the object at a speed of about 3 meters per minute. As described above, the processing of the object surface is continuously performed.
- the reason why the nozzle is rotated at a low speed is that the diameter of the nozzle is very small (0.1 to 5 millimeters), and thus the processing width is also small.

- the other end of the holding portion 122 is integrated with the center of the holding portion 124 extending in the left-right direction and parallel to the surface F in FIG. It is connected.
- One end of the holding portion 124 (the left end in FIGS. 1 and 3) extends toward the surface F and has one end formed between the funnel-shaped portion 6 and the annular portion 8 in the case 4.
- the cross sections of the holding portions 122 and 124 and the legs 120, 126 and 128 are substantially channel-shaped.
- One end of the shaft 1 16 of the main bevel gear 1 18 is fixed to a shaft holding section 130 formed on the holding section 124 so that it cannot be rotated by a nut 132, and the other end is a holding section. It is positioned to protrude from 1 2 4 toward surface F.
- the main bevel gear 1 18 is fixed to this other end.
- the driven shaft 104 of the main crank 106 is rotatably supported on the shaft 111 of the main bevel gear 118 via a ball bearing 134.
- the rotating shaft 108 of the slave crank 110 is rotatably supported by the main crank 106 via a ball bearing 135.
- One end of the spherical joint 112 is fixed to the slave crank 110, and a ball 138 is formed at the other end.
- the ball 138 is rotatably connected to a suitable ball receiving means provided on the other end side of the swinging cylinder 62.
- a sprocket 140 is fixed to the driven shaft 104 of the main crank 106.
- On one foot 120 a geared motor 102 is mounted.
- a sprocket 144 is fixed to the output shaft of the geared motor 102.
- a mouthpiece 144 is wound between the sprockets 140 and 142. Therefore, when the geared motor 102 is energized (operated), the main crank 106 is driven through the sprocket 144, the roller chain 144, the sprocket 140, and the driven shaft 104. It is driven to rotate.
- one end of the above-mentioned spherical joint 1 12 is fixed to the other end side of the swinging cylinder 62, and the ball 1 3 8 is relatively positioned with respect to an appropriate ball receiving means provided on the slave crank 110.
- a configuration for rotatably connecting is also theoretically possible.
- the operation of the universal bearing mechanism 60 will be described with reference to FIGS.
- the main oscillating body 66 is rotatable around the main oscillating axis L1
- the sub oscillating body 68 is rotatable about the sub oscillating axis L2. Therefore, the swing cylinder 62 and the nozzle 64 supported by the driven swing body 68 can freely rotate around the axis P1 of the universal bearing mechanism 60. However, the swing cylinder 62 itself does not rotate around one axis.
- the power is transmitted to the other end of the oscillating cylinder 62 via a spherical joint 112 provided at a portion eccentric from the 10 axis L4.
- the swing cylinder 62 is a universal bearing mechanism.
- the moving cylinder 62 and the nozzle 64 perform rotation and orbital movement around the axis P1 of the universal bearing mechanism 60. .
- the abrasive grains together with the ultra-high-pressure water are supplied from the nozzles 64 rotating and revolving. Fired toward object surface F. After the ultra-high pressure water and the abrasive grains collide with the surface F, they are sucked and collected by the decompression means 22 through the suction hose 20 together with the foreign matter contaminated from the surface F.
- FIGS. 8 and 9 a description will be given of a rotation revolution mechanism 200 partially provided with another embodiment. 8 and 9, the same parts as those in FIGS. 1 to 7 are denoted by the same reference numerals.
- the main bevel gear 118 is fixed to the shaft holding portion 130 of the holding portion 124, but the rotation in FIGS. 8 and 9 is performed.
- the main bevel gear 1 18 rotates 0, that is, the shaft 202 of the main bevel gear 118 is mounted on the shaft holding portion 204 of the holding portion 124 in a ball bearing 200. It is rotatably mounted via the.
- the shaft 202 is further inserted into a hollow shaft (not shown) of a hollow shaft type geared motor 210 fixed to a flange 208 provided on a shaft holding portion 204. It is fixed to the hollow shaft.
- the geared motor 210 when the geared motor 210 is energized to rotate the main bevel gear 118 in a direction opposite to the revolving direction of the main crank 106, the slave crank 110 and the bevel gear 1 are rotated.
- the rotation speed of 14 can be further increased. If the geared motor 210 is configured so as not to be rotated by an appropriate braking means, the main bevel gear 118 can be held in a fixed state.
- the oblique shaft rotation transmission mechanism in the rotation revolving mechanism 100 is composed of a main bevel gear 118 and a bevel gear 114, but is not limited to this configuration. It is not something to be done.
- an oblique shaft rotation transmission mechanism can be constituted by a main roller and a sub-roller having substantially the same shape.
- Each of the main roller and the slave roller has a conical circumferential portion.
- Rotation is transmitted by contact friction generated when the conical surfaces are pressed against each other.
- This configuration is also included in the scope of the present invention.
- the description of the embodiment of the device of the present invention has been made assuming that the device 2 is on the surface in the atmosphere, the device of the present invention can be applied to underwater. In this case, an ice pump or a water-driven ejector can be used as the pressure reducing means 22 instead of the vacuum pump.
