Title:
回転工具用形直し装置
Document Type and Number:
Japanese Patent JP7202403
Kind Code:
B2
Abstract:
A truing device includes a housing and a truing mandrel (1) with a shaft (10) used to mount a circular tool having a concentric opening, in particular a grinding disc (3), and with a first bearing (11) fixed on the housing (4) and located in a first end region of the truing mandrel (1) The shaft (10) includes a hydraulic clamping device (20) having a chamber (21) containing hydraulic medium, to which a pre-clamping pressure can be applied with a preclamping element (23) The hydraulic clamping device is formed from a clamping section (22) lying above the chamber (21) in the radial direction and held in the shaft on both sides. The outer surface of the clamping section forms the clamping surface and which, when the hydraulic pressure in the chamber (21) increases, can be reversibly moved or bent outwards in the radial direction such that a radial clamping force can be exerted on the inner surface of the concentric opening of the circular tool penetrated by the clamping section (22). A method provides for mounting and removing a circular tool on the truing mandrel of a truing device of this kind.
