For achieving the above object, the technical solution used in the present invention is: numerical control four-axis piston external-diameter finishing lathe comprises bed piece and is installed in bed piece four direction of principal axis, accurate main shaft facing each other and servo tailstock barrel system, servo imitative type car unit and double-deck servo anti-cutter unit, accurate main shaft connects actuating unit, accurate main shaft is provided with tool, pattern is fixed on the tool, piston blank is set in the clutch end of tool, tailstock barrel by servo tailstock barrel system compresses, the pressure that compresses is set by digital control system, be fixed with cutter on servo imitative type car unit and the double-deck servo anti-cutter unit, the cutter of servo imitative type car unit prolongs the main shaft axial feed, and cutter withstands on the pattern.
The feed mechanism of above-mentioned servo tailstock barrel system, servo imitative type car unit is the ball lead screw drive mechanism of servo-control system.
Above-mentioned servo imitative type car unit is provided with the fine tuning tool rest fixed cutting tool.
The feed mechanism of above-mentioned double-deck servo anti-cutter unit is that two covers are independent, the ball lead screw drive mechanism of the servo-control system of square crossing.
Above-mentioned double-deck servo anti-cutter unit is fixed with two to fix a cutting tool.
Above-mentioned servo tailstock barrel system comprises servomotor, and ball-screw is connected with servomotor by elastomeric connector, and pilot sleeve mechanism is set in the output of ball-screw, and pilot sleeve mechanism front end is provided with thimble.
Above-mentioned pattern outer contour shape is the shape that piston blank machines, and namely is the model of piston blank machine-shaping.
The present invention adopts above technical scheme; utilize tool and tailstock barrel system tailstock barrel under numerical control is set, to be fixed piston blank; and adopt servo imitative type car unit to fix a cutting tool to compress the mode of pattern; for the cutter of the servo anti-cutter of bilayer unit provides the accurate tool sharpening amount of feeding, guarantee the machining accuracy of piston outer profile size.So only need to just can carry out just processing to the outer chamfering of piston external diameter, piston channel and end face simultaneously to the piston blank clamped one time, operate easy to adjustly, improve machining accuracy and working (machining) efficiency.
Description of drawings now is further described the present invention by reference to the accompanying drawings:
Fig. 1 is the structural representation that numerical control four-axis piston external-diameter finishing lathe of the present invention is clipped servo imitative type car unit;
