Specific embodiment
The polishing fixture of the utility model including clamp body 1 and is arranged on the locating piece 2 at 1 both ends of clamp body and positions
Pressing plate 4.The L-shaped positioning surface 10 that the upper surface of clamp body 1 is made of horizontal location face and vertically locating surface, horizontal location are set on face
There are positioning runner 9, centre position to be equipped with central recess 6, the positioning key 3 of internal thread through hole 13 is provided in central recess 6；Folder
Specific 1 both ends are equipped with positioning groove 7, fasten screw hole 11, and positioning screw hole 8 is equipped in positioning groove 7.Locating piece 2 be equipped with
Positioning convex platform 17 that the positioning groove 7 of clamp body 1 matches, positioning screw hole 16 and stepped hole 15 is fastened, on positioning convex platform 17
Equipped with positioning step hole 14；Positioning screw 5 equipped with rotation in positioning screw hole 16, positioning screw 5 and 16 spiral shell of positioning screw hole
