Abstract

Inventia se refera la o masina de gaurire adînc destinata realizarii alezajelor lungi, în special, la piesele cu configuratie neregulata utilizate în ramura constructiilor de masini. Masina este formata din batiu stabil eschipat cu un grup de actionare, pentru lantul cinematic de antrenare, al tevii portscula, aflat în carcasa fixata pe batiu coroborata cu o sanie principala de avans condusa pe ghidajele batiului ce poarta subansamblul de ghidatre si etansare a tevii portscula coroborat cu menghina de prindere a piesei ssi dispozitivul de rezemare frontala. Masina este prevazuta cu un dispozitiv de prindere a unei tevi portscula cu niste elemente intermediare de prindere cum ar fi o piesa inelara cu cale de rulare conjugata cu niste corpuride rulare, un dispozitiv de alimentare cu fluid si ghidare fiind prevazut cu o sanie intermediara de deplasare relativa, manevrata de un subansamblu cu elemente de siguranta fixarea saniei intermediare pe sania principala fiind asigurata de un dispo zitiv de blocare cu componente mecano-hidraulice, o menghina de prindere a piesei de preclucrat pe sania principlaa fiind asigurata de aceasta cu un subansamblu de piesa dintata cremaliera surub piulita.The invention relates to a deep hole drilling machine for long bore drilling, in particular for irregularly configured parts used in the machine construction branch. The machine consists of a stable shaft with a drive group for the drive kinematics of the hub, located in the casing fixed to the frame, coupled with a main slide running on the guides of the frame bearing the guiding and sealing of the pipe in conjunction with the clamping pin of the workpiece and the front support device. The machine is provided with a clamping device for a pipework with intermediate clamping elements such as an annular track part coupled to some rolling bodies, a fluid supply and guidance device being provided with an intermediate travel sleeve relative to one of the sub-assemblies with safety elements securing the intermediate sleeve to the main sleeve being provided by a locking device with mechanical-hydraulic components, a clamp for clamping the workpiece on the main sleeve being provided by it with a piece subassembly toothed nut screw bolt.
