Compensation method for positioning error of center-driven dual-mode disc casting machine

The invention discloses a method for compensating the positioning error of a center-driven dual-mode disc casting machine, which comprises the following steps of: performing equal-precision direct measurement on the position of a disc, obtaining a reasonable measurement result, analyzing and processing the error, judging whether the measurement result has a system error or not, and eliminating the error deviation by adopting a correction method. In consideration of the factor of a wear clearance of meshing of a driving gear and a driven gear, the position error generated each time is offset to the minimum value by accurately calculating the transmission ratio of a speed reducer, and the position offset generated by a disc casting machine when a furnace of copper liquid is cast by an anode furnace each time is eliminated, so that accurate disc positioning and zero plate taking error are realized, and the normal production order is ensured. 本发明公开了一种中心驱动的双模圆盘浇铸机定位误差的补偿方法，通过对圆盘位置经行等精度直接测量，为得到合理的测量结果，对误差进行分析处理，判断测
