Abstract
The invention relates to a leveling machine. The leveling machine is provided with a base provided with a lower idler wheel set and a first support fixed to the base. A second support is fixedly spliced between the first support and the base. Idler wheel supports provided with an upper idler wheel set are arranged between the first support and the second support. An adjusting device for controlling the interval between the upper idler wheel set and the lower idler wheel set by adjusting the positions of the idler wheel supports is fixed between the idler wheel supports. An eccentric volume measuring device is adopted, through the simple and reasonable design, the eccentric volume generated by rotation of an eccentric shaft is converted into linear displacement, and the phenomenon that when an encoder is adopted for measuring the eccentric volume, due to machine vibration, reading jumps and is instable in the prior art is effectively avoided.
