Axial swing mechanism for in-situ roller coping arrangement

The utility model relates to an axial tilting mechanism of a roller on-line thinning device, comprising a drive motor, a gear, a rack, a sleeve, a guide beam, a moveable guide roll and a roll shaft of guide roll; wherein, an output shaft of the drive motor is connected with the gear and the gear is meshed with the rack; the guide beam is a shape like a Chinese character ''gong'', which is provided with a slot on an upper part. The rack and the gear meshed with the rack are arranged in the slot. The moveable guide rolls are positioned in the two slots at left and right sides of the guide beam; the sleeve is composed of a front sleeve and a back sleeve, which are arranged at the two sides of the guide beam and respectively cut with mounting holes for holding the roll shaft of the guide roll. An end of the roll shaft of the guide roll is positioned on the sleeve through an eccentric gear fixedly connected with the guide roll and the other end is connected with the moveable guide roll. When the gear is rotated by the driving of the motor, the gear and the drive motor can move axially along the rack shaft during the meshing, for driving the sleeve move axially along the guide beam, so that a holding frame of a grinding wheel head and the grinding wheel head can do the axial movement. The utility model has the advantages of simple and compact structure, small space usage, stable operation and strong reliability.
