【Example】

 Hereinafter, an illustrated embodiment of the present invention will be described. In the present embodiment shown in FIGS. 1 to 4, reference numeral 2 denotes a polishing belt device, which is formed by winding a polishing belt 23 around a driving roller 21 and a driven roller 22 in an endless manner. The drive roller 21 is one in which a sponge drum 25 is attached to a rotary shaft 24 attached to the front side of one side of the mounting body 1, and the driven roller 22 on the other side is a long hole 11 formed through the rear side of one side of the mounting body 1. The shaft pin 26 is fastened with a screw 27 and the free drum 28 is rotatably mounted on the shaft pin 26.

Reference numeral 3 denotes an air motor, which encloses the blades 31 which are rotated by press-fitting compressed air to rotate the shaft 32. The motor 3 is provided with a cover body 33 thereof fixed to a mounting upright piece 12 vertically protruding from the mounting body 1, and is arranged vertically above the drive roller 21.

Further, a pulley 34 is attached to the shaft 32 of the motor 3 protruding laterally from the mounting upright piece 12, and a pulley 29 is attached to the rotary shaft 24 of the drive roller 21 protruding laterally from the mounting body 1. Are connected to each other by a pulley 34 and a belt 35. The transmission mechanism is covered with a cover 36 at the side portions of the mounting body 1 and the mounting upright piece 12.

Further, the cover body 33 of the motor 3 is provided with a rearward facing gripping member 4, and a hose from a compressor (not shown) is connected to the inside of the gripping member 4 to connect the motor 3 to the inside of the motor 3. An air passage 41 that is in conduction is arranged. An operation lever 5 is attached to the upper surface of the grip member 4 so as to be vertically rotatable by connecting a pin 51, and a vertically movable pin 52 pressed by the operation lever 5 is arranged below the operation lever 5. ing. The movable pin 52 is fixed to a movable member 53 that divides the air passage 41 by moving up and down in the gripping member 4, and in the lowered state, a conduction passage 54 communicating with the air passage 41 is provided in the front-rear direction. . The movable member 53 is constantly urged to rise by the spring 55.

A guide holding portion 13 having a bolt 14 projecting forward is provided at the front end portion of the mounting body 1 to hold the guide member 6. Since the guide member 6 is bent downward from the end of the mounting portion having the horizontally elongated hole 61 formed therein and has the guide surface 62 in the front-rear direction at the lower end, the horizontally elongated hole 61 is inserted into the bolt 14 and the knob nut is inserted. The guide member 6 is fixed by screwing with 63.

Further, as shown in FIG. 5, a pad 7 is composed of a standing piece 71 and a horizontal pad surface 72, and a bolt hole 73 provided in the standing piece 71 is attached to the bolt hole 1 of the mounting body 1. The bolt surface 74 is pressed between the drive roller 21 and the driven roller 22 by pressing the pad surface portion 72 from the upper side to the lower side of the polishing belt 23 on the lower surface side so that the polishing contact surface of the polishing belt 23 is enlarged. There is.

A support roller 8 is rotatably attached to a lower portion of the rear end of the attachment body 1 at a position below the driven roller 22. Reference numeral 16 is a hole for attaching a suction hose.

Next, the operation of this example will be described. When the compressor is turned on and the grip member 4 is gripped with one hand, the operation lever 5 pivots downward with the pin 51 as a fulcrum. As a result, the movable pin 52 is pushed down, the movable member 53 descends against the spring 55, the conduction path 54 communicates with the air path 41, and compressed air is forced into the motor 3 to rotate the motor 3.

The rotation of the motor 3 causes the drive roller 21 to rotate via the pulley 34, the belt 35, and the pulley 29, and the polishing belt 23 to rotate. It suffices to hold this state and apply it to the material to be polished for polishing. When it is desired to stop the polishing, it is sufficient to loosen the grip of the grip member 4, and the restoring force of the spring 55 causes the movable member 53 to rise and return, thereby blocking the air passage 41 and returning the operation lever 5 to the upper rotation return position. To do.

The feature of this example is that the motor 3 is located vertically above the drive roller 21 and rotates in the same direction, so that the belt transmission mechanism can be easily connected, thus making the compact and lightweight. It is possible to operate with one hand because switching can be linked with gripping.

Further, as shown in FIG. 3, by applying the guide surface portion 62 to the side end surface of the material 9 to be polished by the guide member 6 to perform polishing, the polishing can be guided and smooth straight polishing can be performed. Hairline processing can be performed on the material 9 to be polished. The guide member 6 can change the lateral protruding position by loosening the knob nut 63 and changing the mounting position in the laterally long hole 61. If unnecessary, the guide member 6 may be removed, or the guide surface portion 62 may be placed upward so as not to disturb the user.

Further, since the pad surface portion 72 of the attached pad 7 presses the polishing belt 23 on the lower surface side from top to bottom, the horizontal polishing contact surface of the polishing belt 23 can be expanded to the length of the pad surface portion 72. The polishing surface of can be enlarged and quick polishing can be achieved. If unnecessary, the pad 7 may be removed.

Although the present example is configured as described above, the present invention is not limited to this. For example, the structure of the rotary polishing body formed by endlessly winding the polishing belt around the driving roller and the driven roller, and the mounting means with the mounting body are not limited. The configuration of the rotating device arranged vertically above the drive roller is not limited, and may be an electric motor. A transmission mechanism for transmitting the rotation of the rotating device to the drive roller is also appropriate. Further, the shape of the gripping member is not limited, and the configuration of the operating lever that is connected to the rotating device and controls switching of the rotating device is arbitrary. When the rotating device is an electric motor, switching can be performed so that electric power can be transmitted by pressing the operating lever.

When a guide member that comes into contact with the side surface of the material to be polished and slides is provided, the shape, the mounting position, and the mounting configuration do not matter. Further, when a pad for enlarging the polishing contact surface by the polishing belt is provided, its shape, mounting position and mounting structure are also suitable.
