Abstract
An air cylinder that changes the posture of an automatic wet sanding unit main body having sandpaper mounted thereon is provided with a guide rod, and an outer circumferential surface of the guide rod has grooves that extend along a shaft centerline of the guide rod and have an arc-shaped cross-section. Balls are interposed between a bottom of each groove and an inner surface of a bush that is provided inside the air cylinder. Thus, it is possible to make two objects compatible with each other: to achieve high-accuracy automatic wet sanding by enhancing the adaptability of the sandpaper to the shape of a painted surface through a reduction of the diameter of the piston rod; and to enhance the durability of the automatic wet sanding apparatus.
Claims3
An automatic wet sanding apparatus that performs automatic wet sanding in which a sanding sliding body is pressed against a painted surface of a painted object that has been painted and the sanding sliding body is moved with water flowing between the sanding sliding body and the painted surface to sand down the painted surface,
- the automatic wet sanding apparatus comprising an automatic wet sanding unit main body on which the sanding sliding body is mounted, and a unit support mechanism that supports the automatic wet sanding unit main body and includes an air cylinder that changes a posture of the automatic wet sanding unit main body,
- the automatic wet sanding apparatus further comprising a guide rod that is slidably supported by a bush provided inside the air cylinder, extends toward the automatic wet sanding unit main body, and is coupled to the automatic wet sanding unit main body,
- wherein an outer surface of the guide rod has grooves that extend along a shaft centerline of the guide rod and have an arc-shaped cross-section in a direction orthogonal to the shaft centerline, and balls that allow the guide rod to slide along the bush are interposed between a bottom of each of the grooves and an inner surface of the bush.
