Roll grinder with chock support - has vertically movable pins and horizontally movable wedges for position control

摘要

The roll grinding device for a roll supported by chocks, comprises vertically movable pins for supporting the chocks each pin having a slope at its lower end, and horizontally movable wedge members, each having a slope at its upper end adapted to be mated with the slope of pin, for controlling the vertical positions of the pins. An assembly is provided for moving the wedge members horizontally, and the moving force is limited to a value less than that which can lift the total weight of the roll and the chocks at the supporting pins. An assembly is also provided for engaging the peripheral face of the roll near the chocks and for moving the roll from a non-grinding to a fixed grinding position in the chocks.
