Specific embodiment
Below in conjunction with Figure of description, the utility model is further described.
As Figure 1-Figure 4, a kind of accurate eccentric processing turning clamping jaw, the disk 1 including center opening, the disk 1
Surface be provided with three groups of pushing blocks 2 that can be mobile to aperture center position, the pushing block 2 is solid close to the end surface of the aperture
Surely be provided with eccentric fixture block 3, and the eccentric fixture block 3 on three groups of pushing blocks 2 be stitched together after its be centrally formed one and be used for
The circle of clamping workpiece, and the distance between the center of circle of the circle and the center of circle of 1 aperture of disk are the inclined of workpiece to be processed inner circle
The heart away from.
After workpiece to be processed is clamped by three eccentric fixture blocks 3, disk 1 is fixed on turning equipment, to workpiece
Inner circle carry out turnery processing, due to the axis B in the center of circle of three eccentric 3 inner walls of fixture block compositions and the circle of 1 center opening of disk
The distance between mandrel line A H is the eccentricity of inner circle to be processed, therefore the workpiece inner circle after turning is eccentric structure, and partially
The heart is away from for H.
It is provided with locating piece 4 on one of bias fixture block 3, the surface of the locating piece 4 is provided with for being caught in workpiece
In positioning protrusion be caught in the groove of workpiece in workpiece fixation procedure using positioning protrusion, so that it will not axial rotation,
Convenient for improving machining accuracy.In the present embodiment, the surface for being fixed with the eccentric fixture block 3 of locating piece 4 is provided with the card that section is T-type
Slot 22, the locating piece 4 are installed in the card slot 22, and the positioning protrusion is extend out to outside the card slot 22, the positioning
