A driven gear 29 is provided integrally with the driven pulley 23 via a connecting cylinder 27, and is rotatable with respect to the output shaft 9. As shown in FIG. 4, driven gears 31A, 31B, and 31C mesh with the drive gear 29, and the driven gears 31A, 31B, and 31C are integrally connected to the vertical drive shafts 17A, 17B, and 17C. ing.

At the lower ends of the vertical drive shafts 17A, 17B, 17C rotatably mounted through the revolution turret 11, a support block 35 having a drive bevel gear 33 is integrally provided. Are provided with a plurality of support shafts 37 extending radially. More specifically, referring also to FIG. 3, the vertical drive shafts 17A, 1
A support block 35 is integrally provided at the lower ends of 7B and 17C, and a drive bevel gear 33 is integrally fixed to the support block 35.

An abrasive roller 15 is rotatably mounted on a plurality of support shafts 37 extending radially from the support block 35, and a driven bevel gear 39 is integrally provided with one end of the abrasive roller 15. The driven bevel gear 39 is meshed with the drive bevel gear 33. Further, the abrasive roller 15 is provided with a washer 41 at the tip of the support shaft 37.
The movement in the horizontal direction is stopped by, for example, a bolt as the fastening member 43 via.

A member denoted by reference numeral 45 in the drawing of FIG. 1 is a belt conveyor (not shown) for conveying the work W.
Of the conveyor belt.

With the above structure, as the operation, as shown in FIGS. 1, 2 and 4, when the first drive member 5 is driven, the revolution turret 11 rotates and the abrasive material mounted on the revolution turret 11 is rotated. Roller groups 13A, 13B, 13
C rotates (revolves) in the direction indicated by Z in the drawing of FIG. When the second driving member 7 is driven, the driving gear 29 rotates via the driving pulley 21, the timing belt 25, and the driven pulley 23, and as shown in FIG.
The rotation is transmitted to the driven gears 31A, 31B, and 31c, and the abrasive roller groups 13A, 13B, and 13C rotate (rotate) in the direction indicated by Y in FIG.

Further, each driven gear 31A, 31B, 31
Vertical drive shafts 17A, 17B, 17C provided integrally with C
The abrasive roller 15 rotates (rolls) as indicated by X in the drawing of FIG. 2 through the driven bevel gear 33 and the driven bevel gear 39 by the rotation of.

Thus, the abrasive roller 15 moves in the Z direction, in the Y direction.
In the direction X and the X direction, and can perform three-axis rotation including revolving, rotation, and rolling, and the polishing material is lowered by the lowering of the machine base 3 to the upper surface of the workpiece W placed and transported on the transport belt 45. By bringing the roller 15 into contact, burrs generated in the workpiece processing portion can be uniformly removed in all directions. Further, uneven wear of the abrasive roller 15 can be eliminated.
Further, when replacing the abrasive roller 15, the fastening member 43
By removing the, replacement can be easily performed.

The present invention is not limited to the embodiment described above, but can be embodied in other modes by making appropriate changes.

[0019]

As will be understood from the above description of the embodiment, in short, in the present invention, the vertical drive shaft 1 is provided at a plurality of eccentric portions of the revolving turret 11 which is horizontally rotated.
7A, 17B, and 17C are provided vertically and rotatably. Each support shaft 37 horizontally supported by each of the vertical drive shafts 17A, 17B, and 17C is rotatable about the support shaft 37. An abrasive roller 15 is provided.

Therefore, according to the present invention, by rotating the revolution turret 11, each of the vertical drive shafts 17A, 17A is rotated.
B, 17C, and each vertical drive shaft 17A, 17
B, 17C are rotated to form vertical drive shafts 17A, 17B, 1
When the respective support shafts 37 horizontally supported by 7C are rotated, the abrasive roller 15 supported by the respective support shafts 37 revolves and rotates according to the revolutions and rotations of the vertical drive shafts 17A, 17B, 17C, and the support shaft 37. (Rotation in the X direction) around the center to deburr the upper surface of the work.

Therefore, according to the present invention, a motion combining three revolutions of revolution, rotation and rolling is performed. When a work has a round hole, a square hole, or the like, for example, the abrasive roller 15 is Deburring generated at the periphery of a hole or the like is performed not only in one direction but also in multiple directions, and deburring can be performed effectively.
