Detailed description of the invention
Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is described further:
Conventional hydraulic tongs ramp is divided into two kinds, and one is thinner, offers unthreaded hole 13 for being connected and fixed (hereinafter referred to as ramp part one) at end face; One is thicker, arc surface is offered screwed hole 14 for being connected and fixed (hereinafter referred to as ramp part two).Seeing Fig. 1 a-Fig. 1 b, is the structural representation of ramp part one; Fig. 1 c-Fig. 1 d is the structural representation of ramp part two.The contour structures of two kinds of ramp parts is substantially identical, all has external arc surface 11 that radius is R and radius is the Inner arc surface 12 of r, and the center of circle on external arc surface 11 is O
1, the center of circle on Inner arc surface is O
2, namely there is eccentric structure.
Seeing Fig. 2-Fig. 3, is structural representation of the present utility model.A kind of turning attachment for processing the eccentric inner arc surface of ramp of the utility model, comprise sleeve shaped clamp body 2, locating piece 3 and hold-down screw 4,5, described locating piece 3 is several, radially uniform in clamp body 2, and hold-down screw 4,5 radially or axial restraint ramp 1.
Seeing Fig. 4 a-Fig. 4 b, is the structural representation of clamp body 2 described in the utility model.
In described clamp body 2, one end is provided with ring-shaped step 21, for ramp 1 axial location.
Described clamp body 2 inner surface establishes detent, and by screw 6 stationary positioned block 3, locating piece 3 is wedge shape, the anchor point for radial location that adjacent 2 locating pieces 3 are formed is positioned at circumferentially same, and its center of circle and clamp body 2 center of circle bias, the offset of offset and the corresponding ramp 1 of angle inner arc surface 12 to be processed and location exterior arc surface 11 and angle.
Described radial hold-down screw 4 is arranged between adjacent positioned block 3, correspondingly with ramp cambered surface hole 14 to arrange, its the distribute round heart and clamp body 2 center of circle bias, and the offset of offset and the corresponding ramp of angle inner arc surface 12 to be processed and location exterior arc surface 11 and angle.
Described axial restraint screw 5 is arranged between adjacent positioned block 3, and is fixed in the end face fixing hole 22 on clamp body ring-shaped step 21, correspondingly with ramp end-face hole 13 arranges.
The using method of a kind of turning attachment for processing the eccentric inner arc surface of ramp of the utility model is as follows:
