Zusammenfassung: | To provide a hub type blade fitting structure which enables easy fitting of a hub type blade to a rotary drive shaft with a simple structure, and a substrate cutting device.SOLUTION: A hub type blade fitting structure comprises: a rotary drive shaft which is rotated around an axis, and on a tip side of which a blade fitting shaft, to which a hub type blade is attached, is formed; and a blade fitting member which fixes the hub type blade attached to the rotary drive shaft on the tip side of the blade fitting shaft. The fitting structure has blade pressing means which is located on a base end side of the blade fitting shaft, to which the hub type blade is attached, in the rotary drive shaft, and presses an area including a circumference with the axis as a center that is corresponding to an outer peripheral edge part of a hub of the hub type blade in a radial direction. The blade pressing means is formed integrally with the rotary drive shaft, and a blade body of the hub type blade is pressed by the blade pressing means.SELECTED DRAWING: Figure 1
【課題】簡単な構造によりハブ型ブレードを容易に回転駆動軸に取付けることが可能とされるハブ型ブレード取付け構造及び基板切断装置を提供すること。【解決手段】本発明の一態様に係るハブ型ブレード取付け構造は、軸線回りに回転され先端側にハブ型ブレードが装着されるブレード取付け軸が形成された回転駆動軸と、前記回転駆動軸に装着されたハブ型ブレードを前記ブレード取付け軸の先端側で固定するブレード取付け部材と、を備え、前記回転駆動軸において前記ハブ型ブレードが装着されるブレード取付け軸の基端側に配置され、前記軸線を中心とし径方向においてハブ型ブレードのハブの外周縁部と対応する円周を含む領域を押圧するブレード押圧手段を有し、前記ブレード押圧手段は、前記回転駆動軸と一体に形成され、前記ブレード押圧手段によって前記ハブ型ブレードのブレード本体を押圧するように構成されていることを特徴とする。【選択図】図1 |
