Definitions
- the present invention relates to a device arranged so as to ensure, automatically and continuously, the adjustment of the position of the centers of oscillation of the pendulum movement rods which support the blade-holder frame of a machine for sawing marbles, granites and other hard stones.
- Fig. 1 is a side view very schematically showing the general arrangement of a sawing machine equipped with a rotary eccentric device according to the invention.
- Fig. 2 shows in the same way, but on a larger scale, the detail of the control mechanism of the envisaged device.
- Fig. 3 is a detail view in elevation from the front.
- Fig. 4 is a geometric diagram illustrating the operation of the device.
- the axes or pivots 1 and 2 on which the rods 3 and 4 of the pendular blade-holder frame 5 of a machine for sawing marble, granite and other hard stones are articulated, are supported by discs or eccentrics 6 and 7 which are regularly driven in rotation during the downward movement of said frame 5 following the advance of the cutting work, in order to continuously compensate for the variation which affects the position of the small end 8 as and when that the actuating rod 9 set in motion by the rotation of the flywheel 10 moves vertically downwards.
- each link 4 is in the form of a gantry in order to support the two opposite sides of the blade holder frame 5.
- Fig. 4 shows that the discs or eccentrics 6 and 7 which support the rods 3 and 4 rotate so as to bring the pivots 1 and 2 on the opposite side of said eccentric
