MACHINE-TOOL FOR CALIBRATING THE BEAM MADE OF NATURAL STONE Russian patent published in 1995 - IPC

FIELD: manufacture of building materials. SUBSTANCE: machine-tool for calibrating the beam made of natural stone has a bedplate, a continuous action conveyer, two working bodies, clamping rollers and fixtures for centering the beam before and after its calibration, correspondingly, located symmetrically to the longitudinal axis of the conveyer. The working bodies are disposed symmetrically to the longitudinal axis of the conveyer. Each working body is made in the form of the side milling cutter mounted on the free end of the cantilevered shaft and the motor kinematically connected with the latter. The longitudinal axes of the cantilevered shafts are located on one straight line which is oriented perpendicular to the vertical plane passing through the longitudinal axis of the conveyer. Each fixture for centering the beam after its calibration has a centering roller mounted for rotating around its longitudinal axis. The bedplate has supports for placing the clamping rollers and fixtures for centering the beam before and after its calibration, correspondingly. The clamping rollers are spring-loaded relative to the corresponding support. The longitudinal axis of each centering roller is located parallel to the plane of the corresponding side milling cutter. The longitudinal axis of one of the clamping rolls and the longitudinal axes of the centering rollers are located in one plane perpendicular to the longitudinal axis of the conveyer. EFFECT: enhanced quality. 5 cl, 3 dwg
