UNIVERSAL WOOD-WORKING MACHINE Russian patent published in 1995 - IPC

FIELD: wood-working industry. SUBSTANCE: proposed machine has a housing, a working table, an engine, and an instrumental shaft placed on the turn plate and connected with the engine by the belt transmission. The machine is equipped with the lifting drive of the instrumental shaft. The housing has a longitudinal window or feeding workpieces along the inner surface of the working table. The engine is placed on the turn plate. The lifting drive of the instrumental shaft is equipped with the helical gear and the friction fixing arm. The nut of the helical gear is hinged with the turn plate. The screw is connected with the machine housing through a spherical hinge including the split spherical bushing mounted in the cone cradle of the housing and in the screw groove. The fixing arm has a rotary shaft with a cam mounted in the housing and a yoke one end of which interacts with the cam and the other one interacts with the split spherical bushing through the inner cone. The machine is equipped with a dismountable square including a thrust gage, a shoe and the fixing arm. The corresponding longitudinal and transverse guideways interacting with the reciprocal parts of the shoe are made on the housing and on the working table. The instrumental shaft has two cantilevered stems. The pulley of the belt transmission and the disk saw are mounted on one of them. The milling cutter, for example, is set up on the second. The machine is equipped with a detachable fixture including a guideway fastened on the machine housing. A tailstock and a carriage are set up on the guideway. A cantilever is mounted on the carriage for the transverse displacement and rotating. A prop and exchangeable articles for fixing the blanks or the cutting tool mounted on the instrumental shaft are fixed on the cantilever. EFFECT: enhanced technological opportunities, enhanced efficiency and quality of processing, decreased vertical dimension of the machine. 4 cl, 13 dwg
