Feeding tool rest for non-circular and eccentric circular turning of numerically controlled lathe

The invention discloses a feeding tool rest for non-circular and eccentric circular turning of a numerical control lathe, and relates to the technical field of lathe tool rests. The device comprises a mounting cover, a linear motor is mounted in the mounting cover, a connecting plate is mounted on the linear motor, a grating ruler is mounted in the mounting cover, the grating ruler is connected with the connecting plate, and a mounting rod with one end located outside is mounted on the connecting plate. Compared with the mode that a motor drives a lead screw to drive, the linear motor is matched with the grating ruler, the precision is higher, errors are reduced, the positioning rods on the mounting plate can move at the same time through the driving mechanism, the positioning rods can rapidly abut against the tool, screws do not need to be screwed one by one, use is more convenient, and the machining efficiency is improved. Time is saved, the situation that the positioning rod abuts against the cutter to cau
