  • Apparatus for abrasive machining of workpieces
    Patent number: 4453348
    Abstract: An apparatus for abrasive machining of workpieces comprises a base in the form of a carriage, a tool head having a spindle with an abrasive tool fastened thereto, an articulated four-bar linkage, a drive for rotating the abrasive tool and an actuating cylinder for urging the abrasive tool to a workpiece, the actuating cylinder being pivotally mounted on the base and a movable link thereof being pivotally connected to one link of the articulated four-bar linkage. The spindle of the tool head is arranged in a plane of the articulated four-bar linkage and connected to the drive for rotating the abrasive tool through a telescoping cardan shaft to thereby considerably reduce the bulk of the tool head movable parts and improve the tracing of the tool over the surface of the workpiece being machined.

  • Device for abrasive cleaning of blanks shaped as bodies of revolution
    Patent number: 4407095
    Abstract: A device for abrasive cleaning of blanks shaped as bodies of revolution is intended to be used in the shops of metallurgical and engineering works for rough grinding of external surface of blanks. The device comprises two wheelheads with rotating tools (7), a movable table (2), a headstock (3) and a footstock (4), carrying centers (5) for the blank, and a blank rotation drive (17). On the table (2) there are mounted a stand (13) and the footstock (4) interconnected by two guides (15) disposed in a vertical plane passing through the line of the centers (5). The headstock (3) is mounted on the guides (15) to be displaced along them.

  • Thrower of transported materials
    Patent number: 4202439
    Abstract: A thrower constructed for the mining industry and comprises a rotatable rotor pivotally connected by means of at least one connecting rod with a bucket adapted to receive and unload material. The spacing of the axis of rotation of the rotor from the axis of rotation of the adjacent pivot of the connecting rod is twice the spacing between the axes of rotation of the two pivots of the connecting rod, parallel with the axis of rotation of the rotor. In operation, the drive of the thrower effects rotation of the rotor and of the connecting rod in the same direction at the same speed, as well as rotation of the bucket in the same direction at a speed which is twice the rotation speed of the rotor. The material is loaded into the bucket in the lower portion of the rotor, since the absolute speed equals zero at this point of its path.
