The specific embodiment

The specific embodiment one: in conjunction with Fig. 1-Fig. 4 explanation, the eccentric arc turning clamp device of present embodiment is made up of two clamp bodies 1, front clamp 2, back acrosome 3 and eccentric top board 4; Front clamp 2 and the coaxial setting of back acrosome 3 along continuous straight runs, the profile of front clamp 2 and back acrosome 3 is cylinder, the external diameter of front clamp 2 and back acrosome 3 equates, the top and bottom of front clamp 2 and back acrosome 3 outer walls respectively are fixed with a clamp body 1, and (present embodiment adopts welding with front clamp 2, back acrosome 3 and two clamp bodies 1 are fixed together), two clamp bodies 1 are symmetrical arranged with respect to the central axis of front clamp 2 with back acrosome 3, be provided with cavity 7 between front clamp 2 and the back acrosome 3, eccentric top board 4 is packed on the outer face of back acrosome 3 (present embodiment adopts welding that eccentric top board 4 and back acrosome 3 are fixed together), be processed with one first hole 4-1 and two second hole 4-2 on the eccentric top board 4, the first hole 4-1 is positioned on the center of eccentric top board 4, two second hole 4-2 are symmetricly set on respect to the first hole 4-1 on longitudinal center's axis of eccentric top board 4, are processed with two connecting hole 1-1 with cavity 7 opposite position places on each clamp body 1.

In the present embodiment, two clamp bodies 1, front clamp 2, back acrosome 3 and eccentric top boards 4 require to select for use solderability good the material that intensity is high.

The specific embodiment two: in conjunction with Fig. 2 and Fig. 3 explanation, the madial wall of the clamp body 1 of present embodiment and front clamp 2 and back acrosome 3 adjacent parts are fitted on the outer wall of front clamp 2 and back acrosome 3, the longitudinal cross-section of the lateral wall of clamp body 1 is shaped as arc, help closely contacting, guarantee the stability of processing with processed eccentric arc part.Other is identical with the specific embodiment one.

The course of work: the tail top centre bore that the eccentric orfice that two second hole 4-2 use when being two clamp bodies 1 of anchor clamps processing, the first hole 4-1 use during for processing parts.The eccentric throw that figure paper size by part calculates two second hole 4-2 is e, and outer arc leaves surplus during clamp body 1 part processing.On engine lathe, use the front clamp 1 of four paws chuck clamping device, the processing first hole 4-1 on eccentric top board 4, and by two second hole 4-2 of eccentric throw processing; Utilize two second hole 4-2 to beat and show centering (guaranteeing eccentric arc part and grip device axiality and linearity requirement) and two clamp bodies 1 are carried out eccentric turning respectively, guarantee that the outer arc of two clamp bodies 1 is consistent with eccentric arc part inner arc; The eccentric arc part that is processed with four shoulder holes is loaded on two clamp bodies 1, four shoulder holes are corresponding one by one with four connecting hole 1-1 on two clamp bodies 1, four compress double-screw bolt 5 and pass the connecting hole 1-1 on eccentric arc part corresponding shoulder hole and the clamp body 1 one by one and use locking nut 6 lockings, part clamping.
