Detailed description of the invention:
Below in conjunction with accompanying drawing, the utility model is described in further detail:
By Fig. 1 in conjunction with shown in Fig. 2, this kind of screw pump rotor abrasive band shaping grinding device, comprise a gripper shoe 1, its unique distinction is: described device also comprises base 3, buncher 13, enclosed abrasive band 4, driving wheel 2, regulating wheel 5, two support wheels 12, the contact wheel 11 with contact wheel bracing frame 10 and cylinders 7.
Wherein, in gripper shoe 1, have recess, described recess is for being fixedly connected with the cross connecting plate 8 of cylinder 7; Together with base 3 is bolted with gripper shoe 1, the other end of base 3 has the hole being connected with lathe guide rail connector, drives whole shaping grinding device together to move in grinding, completes the processing of whole screw rod; Buncher 13 is fixed on the dorsal part of gripper shoe 1 by connecting plate for electric motor 14.
Above described gripper shoe inner recess, the axle of driving wheel 2 does coaxial connection through gripper shoe 1 with the driving shaft of buncher 13; Regulating wheel 5 is positioned on same level line with driving wheel 2, and the axle of regulating wheel 5 is connected with the baffle ring of its dorsal part through gripper shoe 1.In addition, in described gripper shoe, started by the axis hole place of regulating wheel 5, have chute, described chute is embedded in spring 6, and the movable end of spring 6 touches mutually with regulating wheel 5, and the other end of spring 6 is fixed in described gripper shoe.Like this, regulating wheel can only slide under the effect of spring force in chute, plays the effect in pretension abrasive band.
Be fixed with respectively the support wheel 12 of buried bearing in the arranged on left and right sides of described gripper shoe inner recess; Cylinder 7 is fixed on cross connecting plate 8 by vertical connecting plate 9, the piston rod external part of cylinder 7 is connected with contact wheel bracing frame 10, contact wheel 11 contains bearing, is fixed in contact wheel bracing frame 10 by axle, plays the motion of transmitting abrasive band and the effect that meets driving wheel cornerite.The most important thing is, as shown in Figure 2, the cross section contour in helical pitch of axial cross section that the cross section molded line 15 of contact wheel 11 is screw pump rotor.
