Pinion and rack type steering engine piston rolling rivet device

The invention discloses a pinion and rack type steering engine piston rolling rivet device. The pinion and rack type steering engine piston rolling rivet device comprises a rack shaft sleeved with a piston; a rack shaft comprises a supporting shaft, and a limiting base for limiting one end of the rack shaft, an automatic resetting device and a supporting base for supporting the rack shaft are arranged on the supporting shaft; the rack shaft is sleeved with a limiting sleeve attached to the end of the piston, extrusion wheels arranged on a rolling rivet machine are arranged on the two sides of the piston and the two sides of the limiting sleeve respectively, and extrusion grooves matched with the limiting sleeve and the piston are formed in the extrusion wheels. According to the pinion and rack type steering engine piston rolling rivet device, the automatic resetting device is adopted, when the rack shaft and a roller are not consistent in center height and the rolling rivet machine is used for piston rolling riveting, automatic adjustment of the center height and resetting can be carried out, and the maneuverability is good; meanwhile, the limiting sleeve is adopted for limiting, and the piston is accurately positioned.
