As explained above, the present invention is arranged and held around a disc-shaped Chiaria plate whose rotation center is located outside the outer diameter of the grinding wheel and which is arranged so that a portion of the periphery overlaps with the grinding wheel. This method uses intermittent indexing motions of the Chiaria plate to sequentially transport a plurality of workpieces between two grinding wheels whose grinding surfaces are placed opposite each other, grind both sides of the workpieces at the same time, and transport them sequentially. A grinding device includes a rotating shaft that has a grinding wheel at one end and is connected to a rotating means to rotate the grinding wheel, and a rotating shaft that is rotatably supported so as to be movable integrally in all directions. The cylindrical body is provided with a threaded portion on a part of its outer periphery, and the cylindrical body is supported so as to be slidable in the direction of the ball, and a worm wheel screwed onto the threaded portion of the cylindrical body is rotatably mounted on the shaft. One side of the grinding wheel head is composed of a casing that is immovably supported in the direction, and a cutting feed mechanism of the grinding wheel equipped with a worm gear that meshes with the worm wheel of the casing. A hollow shaft that rotatably supports the plate shaft is supported on a fixed substrate so as to be able to reciprocate in a direction perpendicular to the grinding wheel axis, and a driving shaft is rotatable in the hollow shaft perpendicular to the reciprocating direction. A worm gear and an eccentric cam ring are mounted on the neck protector drive shaft via a continuation device such as a clutch, and the worm gear is meshed with a worm wheel integrated with the plate shaft. A core cam ring is inserted between the two crotches of a locking arm fixed to the fixed base plate, and the drive shaft can be controlled and driven from an end on the eccentric cam ring side by an external drive device,
Since the disconnection device such as the clutch is controlled to be connected during indexing and disconnected during grinding, only the work carried between the grinding wheels while the carrier plate is stopped at the index position during grinding, both sides of the workpiece. The grinding process is performed by the rotation of the grinding wheel and the reciprocating movement of the workpiece in a direction orthogonal to the axis of the grinding wheel.The grinding process allows the ejection of ground workpieces at positions other than the index position and the replenishment of unground workpieces during the grinding process, allowing continuous grinding work. It can be implemented in

目して上記構成としているのである。
In particular, by driving the drive shaft from the end on the eccentric cam ring side, the overall structure can be further simplified. That is, while the indexing operation must be paused during the grinding process, the reciprocating movement is designed with the focus on the fact that there is no problem even if it is activated during the indexing process.

1 A plurality of workpieces placed and held around a disc-shaped carrier plate whose rotation center is placed outside the outer diameter of the grinding wheel and whose peripheral edge partially overlaps the grinding wheel are placed on the carrier plate. In a grinding device that uses intermittent indexing operations, the grinding surface is sequentially carried between two grinding wheels arranged opposite each other, both sides of the workpiece are simultaneously ground, and the workpiece is carried out sequentially. a rotating shaft that is connected to a rotating means to rotate the grindstone; and a cylinder that supports the rotating shaft so as to be rotatable and movable integrally in the axial direction, and that has a threaded portion on a part of its outer periphery. a casing that supports the cylindrical body so as to be slidable in the axial direction and supports a worm wheel that is rotatably but not movable in the axial direction and that is screwed into the threaded portion of the cylindrical body; and a worm of the casing. One side of the grinding wheel head is composed of a cutting feed mechanism of the grinding wheel equipped with a worm gear that meshes with the wheel, and a plate shaft is fixed at the rotation center of the carrier plate, and a hollow shaft rotatably supports the plate shaft. A fixed substrate is supported so as to be able to reciprocate in a direction perpendicular to the grinding wheel axis, and a drive shaft is rotatably supported on the hollow shaft in a direction orthogonal to the reciprocating direction.
A worm gear and an eccentric cam ring are mounted on the drive shaft via an intermittent device such as a clutch, the worm gear is meshed with the worm wheel integrated with the plate shaft, and the eccentric cam ring is fixed as described above. It is inserted between the two crotches of a locking arm fixed to the base plate, and the drive shaft can be controlled and driven from the end on the eccentric cam ring side by an external drive device, and the disconnection device such as the clutch can be driven by an external drive device. A grinding device characterized in that it is controlled to be connected during indexing and disconnected during grinding.
