Title:
駆動軸とバフホイールとの連結構造及び該連結構造を有する研磨装置
Document Type and Number:
Japanese Patent JP7432912
Kind Code:
B2
Abstract:
To achieve down-sizing of a polishing device while enabling easy replacement of a buff wheel in the polishing device.SOLUTION: In a connection structure of a buff wheel 12 and a drive shaft 11 for rotating the buff wheel, the buff wheel has a coupling 24, which fits to the drive shaft, at a central part. The coupling 24 has a fitting hole fitting to the drive shaft 11, and a connection pin 29 which traverses the fitting hole and is orthogonal to an axis of the fitting hole. A slit 22, which can fit to the connection pin 29, is formed at a tip of the drive shaft 11. A groove is provided at an end position of the slit 22. By fitting of the drive shaft 11 and the coupling 24, the connection pin 29 is inserted in the slit 22, and by relative rotation of the drive shaft 11 and the coupling 24, the connection pin 29 fits in the groove, and the buff wheel 12 and the drive shaft 11 are connected.SELECTED DRAWING: Figure 3
