Abstract

1. Portautensile per un apparecchio di preimpostazione o simili.2.1 L'invenzione riguarda un portautensile per un apparecchio di preimpostazione o simili, costituito da una bussola conica alloggiante il gambo conico di un utensile, bussola che è trattenuta girevolmente in un cannotto fisso alla scatola ed è supportata da supporti, assiale e radiale. La combinazione di supporti assiale e radiale, o anche l'impiego di un cuscinetto combinato assiale/radiale, è tecnicamente dispendiosa e quindi impegnativa come costi. Nonostante il dispendio tecnico non è garantita una sufficiente assenza di gioco.2.2 Per ottenere un supporto di alta precisione per la bussola conica nel cannotto, è previsto secondo l'invenzione che almeno il supporto radiale sia formato con una resina da getto iniettata in una cavità delimitata dal cannotto e dalla bussola conica in esso inserita.2.3 Supporto di alta precisione per le parti rotanti.(Figura 1).1. Tool holder for a presetting device or similar. 2.1 The invention relates to a tool holder for a presetting device or similar, consisting of a conical bush housing the conical shank of a tool, a compass which is rotatably held in a sleeve fixed to the box. and it is supported by supports, axial and radial. The combination of axial and radial bearings, or even the use of a combined axial / radial bearing, is technically expensive and therefore demanding as costs. Despite the technical expenditure, a sufficient absence of play is not guaranteed.2.2 To obtain a high precision support for the tapered bush in the quill, it is foreseen according to the invention that at least the radial support is formed with a casting resin injected into a cavity delimited by the quill and the conical bush inserted in it.2.3 High precision support for the rotating parts (Figure 1).
