SPECIAL MACHINE TOOL FOR WORKING OF LATERAL FRAME OF BOGIE BOLSTER OF FREIGHT CARS

摘要

A special machine tool for working of lateral frame of bogie bolster of freight cars contains a bed with tool units located on it and equipped with independent drive which include tool heads fixed on the mobile power tables and made with possibility of operational replacement of installed on them finishing tool, means of control of the drives of tool units and hydraulic drives of fastening of workpiece in the position of working, means of oil supply to the rotary kinematic pairs of tool units and pairs of slipping of power tables, means for fastening of component in the position of working, which include the rise-and-fall limiters of the lower position of component, moved by hydraulic cylinder, located symmetrically relative to the longitudinal axis of component a support of its transverse fastening and symmetrically located relative to transverse axis of symmetry, equipped with supportsand connected with the drive the levers for fastening of component on top on the limiters of its lower position in the position of working. It additionally contains an intermediate equal-arm lever which arms with the aid of a rod are connected with the levers of centering and fixation of component in its longitudinal direction. The drive of levers is made in the form of hydraulic cylinder which housing through the attenuator is movably fastened to one of the levers of centering, and its stock isconnected to one of the arms of intermediate lever.
