The utility model limits the position of thumb wheel on the one hand by upper cover, avoid thumb wheel axially moving at support bar, upper cover also has protective action in addition, prevents the chip in process from entering in overcoat, affects the flexibility ratio of thumb wheel.
Preferably, be provided with in described centre bore for the spacing convex key of support bar circumference, support bar is provided with the groove coordinated with described convex key.
Because upper cover and overcoat keep fixing, keep support bar and upper cover to fix in circumferential, the circumference that can realize support bar and overcoat is spacing; Axial limiting in the utility model is realized by " sunk key cooperation ", and in centre bore, arrange convex key, such as, in circular port, arrange D type key, support bar cuts out a plane, to adapt to described D type key, the part reamed is the groove coordinated with convex key.
Preferably, described support bar comprises the body of rod inserted in overcoat, and is positioned at the supporting disk at described body of rod top; The described body of rod has the thread segment coordinated with thumb wheel.
The binding face of supporting disk and workpiece, much larger than shank portion, by increasing supporting surface, is more conducive to horizontal support and calibration.
Preferably, the position that the outer wall of described overcoat is corresponding with thumb wheel is provided with the circumferential handle hole extended, and by handle hole, the thumb wheel in rotatable overcoat, drives support bar lifting.
Preferably, the periphery calibration of described thumb wheel is provided with spliced eye, and described spliced eye is for plugging through handle hole to drive the driving lever of thumb wheel.
The utility model adopts driving lever to provoke thumb wheel, force of being more convenient for, simple to operate, by multiple spliced eye, realizes 360 ° of rotations of thumb wheel, and is not limited only to radian corresponding to described handle hole, to possess larger height adjustment range.
Preferably, the insertion end of described driving lever is thin bar body, and the one end for gripping is thick bar body.Thin bar body is adapted to the miniaturization of whole device, and thick bar body is more convenient for gripping force.
Preferably, the locating hole axially run through is provided with in described support bar.
By the bolt through workpiece and locating hole, by workpiece and flexible levelling device fixing on the table, make device of the present utility model realize the integrated of adjustment means and fixture, without the need to coordinating workpiece making special tooling again.
The utility model has following advantageous feature:
1, structure is simple, and compact is easy to operate;
2, without the need to coordinating each production special tooling to fix workpiece again;
3, large cutting force can be born, directly on former process program basis, after padded smoothing, directly can carry out Milling Process;
4, the locating hole at center is through hole, can double as fixture and use.
