Abstract

Inventia se refera la un dispozitiv de aschiere a pieselor profilate, în special a celor cu dublu profil axial, cum ar fi racordurile fixe de îmbinare a furtunelor de la instalatiile de prevenire si stingere a incendiilor (PSI) exploatabil pe masini-unelte mai ales pe cele de frezat. Dispozitivul este format dintr-un subansamblu portscule montat în axul principal al masinii, coroborat cu un subansamblu de prindere si manevrare a semifabricatului montat pe batiu în locul mesei. Subansamblul portscule este prevazut cu doua freze profilate coroborate cu un dorn central ce apasa asupra unui cep conic de presare asupra unor pene radiale de prindere a unui semifabricat de prelucrat rotit si deplasat axial printr-un ax vertical filetat superior legat de un arbore vertical inferior, coaxial cu primul, între care se afla un cuplaj filetat interior si un cuplaj cu bile coroborate cu un cuplaj unisens pentru a asigura sincronizarea miscarii semifabricatului pe unghiuri si înaltimi corespunzatoareunei came duble frontale, montata pe arborele aferent, în colaborare cu o roata compusa rotita secvential printr-o dantura dispusa pe un traseu compus de catre un lant cinematic interior antrenat la rîndul sau printr-o pereche de roti cilindrice sio pereche conica.The invention relates to a device for cutting profiled parts, especially those with double axial profile, such as the fixed hose couplings of the fire prevention and fire-extinguishing systems (PSI) operating on machine tools especially on the milling cutters. The device is made up of a subassembly mounted in the main shaft of the machine, coupled with a tool holder and handle assembly mounted on the stand in place of the table. The tooling assembly is provided with two profiled cutters coupled with a central mandrel that presses on a tapered pin on pressed radial feathers of a workpiece rotated and axially displaced by a vertically threaded upper shaft connected to a lower vertical shaft, coaxial with the first one, including an internal threaded coupling and a ball coupling coupled with a unisens coupling to ensure the timing of the movement of the blank on the angles and heights of the corresponding front double sprocket mounted on the associated shaft in conjunction with a sequentially rotatable composite wheel through a teeth disposed on a compound path by an internal cinematic chain trained in turn by a pair of cylindrical wheels and a conical pair.
