Abstract

Inventia se refera la un procedeu si la un dispozitiv pentru compresarea automata a uzurii sculei, folosit la operatiile de prelucrare a alezajelor la unitati de lucru care au posibilitatea de retragere a vîrfului cutitului dupa fiecare trecere. procedeul pentru compensarea automata a uzurii sculei la operatiile de prelicrare a alezajelor, în scopul cresterii preciziei dimensionale si a îmbunatatiri calitatii suprafetelor prelucrate, prevede aplicarea unor impulsuri unui motor electric, impulsuri care condul la deformarea eleastica a suportului unei scule de taiere în conditiile în care deformarea elsastica este rezultatul deplasarii laterale a suportului cutitului provocata pe de o parte de alunecarea pe suprafata în panta a capului uneei tije prin care sînt transmise impuilsurile si pe de alta parte de sectionarea partiala printr-o fanta a suportului sculei. Dispozitivul pentru aplicarea procedeului include un reductor ce este actionat de un motor electric prin impulsuri. Roata dintata finala a reductorului are practicata pe alezajul interior un filet pentru montarea unui surub care face legatura, prin intermediul unui cilindru hidraulic cu o tija ce trece prin interiorul arborelui principal si al barei de prelucrare. Tija este prevazuta la capat cu o suprafata plana înclinata. Sub impulsurile primite de la motor, capul tijei aluneca pe suprafata încvlinata si asigura deformarea elastica a suportului sculei prin deplasarea laterala a sa.The invention relates to a process and a device for automatically compressing tool wear, used in bore machining operations at work units which have the possibility to retract the knife tip after each passage. the process for automatically compensating tool wear for bore-bore operations in order to increase dimensional precision and improve the quality of the processed surfaces provides for the application of pulses to an electric motor impulses which cause the elec- tric deformation of the support of a cutting tool in the conditions elsastic deformation is the result of the lateral displacement of the knife holder caused on the one hand by sliding on the surface of the head of the rod rod through which the impulses are transmitted and partly by the partial section through a tool holder slit. The device for applying the process includes a reducer driven by a pulse electric motor. The gear end gear gear has a thread on the inner bore for mounting a screw that connects by means of a hydraulic cylinder with a rod passing through the inside of the main shaft and the processing bar. The stem is provided at the end with a flat planar surface. Under the impulses received from the motor, the rod head slides over the twisted surface and ensures the elastic deformation of the tool holder by its lateral displacement.
