Abstract

Inventia se refera la o masina de polizat alezaje lungi, în special pentru finisarea interiorului tevilor. Masina conform inventiei este formata dintr-o platforma deplasabila pe sine, ce sustine o platforma intermediara reglabila în plan vertical, depurtare a unui subansamblu portscula. Masina este prevazuta cu o platforma intermediara, deplasabila plan paralel fata de platforma deplasabila prin intermediul unui grup motor de actionare, ce asigura reglarea pozitiei de lucru a unui ax principalp ortscula sustinut de un cadru purtator mobil legat la platforma intermediara printr-o articulatie coroborata cu un subansamblu elastic de asigurare a unei presiuni de lucru la care actionarea axului principal este asigurata de un grup motor amplasat pe platforma intermediara.The invention relates to a long boring polishing machine, especially for finishing the interior of the pipes. According to the invention, the machine consists of a self-propelled platform which supports a vertically adjustable intermediate platform for the removal of a sub-assembly. The machine is provided with an intermediate platform, displaceable parallel to the platform by means of a drive motor drive, which regulates the working position of an ortscula main shaft supported by a mobile carrier frame connected to the intermediate platform by a hinged joint an elastic subassembly for providing a working pressure at which the drive of the main shaft is provided by an engine group disposed on the intermediate platform.
