Engine cylinder body simulation process cylinder cover circulation method

The invention discloses an engine cylinder block simulation process cylinder cover circulation method, which comprises a transfer robot and a horizontal machining station which are sequentially arranged along a cylinder block feeding direction, and the horizontal machining station comprises a first horizontal machining center and a second horizontal machining center. The transfer robot is used for grabbing the cylinder body from the upstream roller line to the first horizontal machining center and the second horizontal machining center and grabbing the cylinder body machined by the first horizontal machining center and the second horizontal machining center to the downstream roller line. In the invention, the transfer robot only needs to grab the workpiece in the process of finely boring the cylinder hole and the gear train hole, so that the situation of station sharing in the prior art is avoided, the production cycle is shortened, and the production efficiency is improved; the original cylinder cover surfac
