The cost of small lot and single-piece work to be greatly improved.Traditional processing method during single-piece work, cylindrical
Although size can reach tolerance, but piece lower mold after combination circumference circularity it is difficult to ensure that, respectively
Between individual piece, easily there is deviation in concentricity.
Utility model content
In order to solve piece part outer fixture of the prior art, use stationary fixture, fixture when grinding only
Can clamp a workpiece, the small batch caused adds the high problem of fixture cost in man-hour, and this utility model provides
A kind of piece cylindrical batch grinding precise clamp, it is possible to achieve the grinding of circular assembled piece type lower mold cylindrical, and this folder
Tool can also realize batch grinding.
To achieve these goals, this utility model adopts the following technical scheme that

Entering centralized positioning block, right fixed plate is inserted centralized positioning block by right side；Pressing plate inserts left fixed plate respectively and the right side is solid
Determine in the notch of plate；Left fixed plate, right fixed plate and centralized positioning block enclose and connect formation fluting with grafting workpiece.
Further, described piece cylindrical batch grinding precise clamp also includes left plate squeezing and right plate squeezing, described
Left plate squeezing be connected with the left side threaded engagement of centralized positioning block, the right side of described right plate squeezing and centralized positioning block
Threaded engagement connects.
Further, described centralized positioning block is regular hexagon.
Further, the described pressing plate inserted respectively in left fixed plate and right fixed plate notch is tight by trip bolt
Gu.
Further, described workpiece has both-side opening, and workpiece is plugged on left fixed plate, right fixed plate and center
Locating piece encloses in the fluting connecing formation, and the bottom surface of this workpiece contacts with centralized positioning block, and pressing plate is crimped on workpiece
Opening in.
Further, described workpiece inserts described fluting according to circumferential arrangement, forms circular assembled piece type work
Part, is crimped adjacent two workpiece by pressing plate.
Further, described workpiece is circular assembled piece type lower mold.
Beneficial effect: piece cylindrical described in the utility model batch grinding precise clamp, due to centralized positioning block
For regular polygon, left fixed plate, right fixed plate shape suitable with centralized positioning block respectively, left fixed plate by
Centralized positioning block is inserted in left side, and right fixed plate is inserted centralized positioning block by right side so that left fixed plate, the right side are fixed
Plate and centralized positioning block enclose the fluting connecing formation, can the shape of adaptive centralized positioning block, form multiple fluting,
Clamp multiple workpiece, it is possible to achieve grinding in batches simultaneously.
