Piston machining center

A piston machining center belongs to the technical field of machining centers and comprises a workbench and a machining tool body arranged on one side of the top of the workbench, a bearing plate is fixedly mounted on the other side of the top of the workbench, a conveying frame is fixedly mounted on the top of the bearing plate, and a guide assembly is mounted at the bottom of the conveying frame. A guide plate is arranged to play a role in guiding a piston in the conveying frame, the situation that the piston inclines in the downward sliding process is avoided, and in addition, a hydraulic cylinder A, a push plate, a hinge rod, a sliding plate and an adjusting rod are arranged to adjust the position of a wire guide plate; according to the piston feeding device, the inclined L-shaped feeding plate is arranged, so that the pistons with different lengths can be guided and limited, the application range is large, feeding work is facilitated, the piston machining efficiency is improved, and the pistons falling o
