The specific embodiment
Embodiment one
The accurate screw mandrel grinding machine of present embodiment as shown in Figure 1, its basic structure is: vertically an end of lathe bed main body 1 is settled the headstock 2, the other end is settled tailstock 3.Vertically be mounted with bistrique 4 on the horizontal lathe bed planker of lathe bed main body middle part one side.Main motor 5 and main shaft 6 are equipped with in the headstock 2 places.Vertically on the lathe bed main body 1 drive lead screw 7 that is used to realize grinding screwfeed campaign is housed.Bistrique 2 contains the emery wheel that grinding motor 8 drives.Main motor 5 adopts servomotor, this servomotor is placed on the headstock 2, its output shaft is connected with main shaft 6 transmissions in being supported on the headstock by meshed transmission gear, vertically drive lead screw 7 one ends of lathe bed main body are settled coaxial transmission servomotor 9, and this transmission servomotor connects with drive lead screw 7 by shaft joint 10.
Concrete structure is described below:
1, headstock part---move by AC servo motor 5 after 1: 10 planet-gear speed reducer output, by a pair of gear 13 and headstock spindle 6 direct connections.Headstock dial 11 is fixed on headstock spindle 6 front end faces, rotates (referring to Fig. 4) with headstock spindle.Rear-end of spindle and encoder direct connection.
2, tailstock part---top 14 are contained in the barrel of tail stock, rotate the band reticulate pattern handle 12 of tailstock 3 rear ends, can change the reduction length of sleeve inner spring, to regulate top pressure to the workpiece center hole.Rotate the handle 15 above the tailstock body, shifting block is rotated, can realize the fast advance and retreat of barrel of tail stock.In addition, rotate the square toes handle on the tailstock base front end face, tailstock body is moved along fore-and-aft direction, so just can adjust tailstock centre cover taper hole center line with respect to the concentricity of headstock spindle taper hole center line in the vertical plane that is parallel to the grinding carriage moving direction.Clamping screw below the rotation tailstock base can be fixed on tailstock body and tailstock base on the guide rail of workbench together.
3, traverse feed---vertically lathe bed main body 1 middle part one side is fixed with horizontal lathe bed 18, the cross slide 17 of carrying bistrique 4 is housed on the guide rail of this horizontal lathe bed, drives cross slide 17 motions (referring to Fig. 3) through high accuracy shaft coupling transmission ball-screw and nut by AC servo motor 16.
4, length feed---by the planet-gear speed reducer of AC servo motor 9, connect with ball-screw 7, drive the ball-screw rotation, make table longitudinal movement (referring to Fig. 2) through shaft coupling 10 through 1: 10.
