Extension bar 7, the extension bar 7 are fixed on the top surface of cam 2.
The distance of the bottom surface of the cam 2 to through-hole 21 is greater than the side of cam 2 the distance between to through-hole 21；
The groove 11 is U-type groove, and the both ends of the lifting shaft 3 can only move up and down in U-type groove；
The lifting shaft 3 is fixedly connected with mode for welding, key connection or interference fit, in the present embodiment with through-hole 21
Lifting shaft 3 is fixed with the mode that is fixedly connected of through-hole 21 using welding manner；
4 inner ring of bearing is fixedly connected with lifting shaft 3, and 4 outer ring of bearing and roller 5 are rolled and connected；
Equipped with long rod set 8,8 sets of the long rod set can more laborsaving, side by lever principle in 7 outside of extension bar
Just rotation cam 2；
The clamping sleeve 6 is arranged between bearing 4 and cam 2, prevents bearing 4 from deviating outward, is detached from roller 5；
The another side and bottom surface of the cam 2 are plane, the distance of through-hole 21 to planar side and general workpiece
9 reach height on 5 surface of roller, and unanimously, the distance of through-hole 21 to bottom surface is the common height of required lifting workpieces 9, is more held
It is fixed easily working standard height；
The mechanical elevating of double flat table top curved cam 2 described in a kind of and the application method of positioning device,
A, using the mechanical elevating and positioning device of more than two above-mentioned double flat table top curved cams 2, according to processing institute
The distance that through-hole 21 arrives 2 planar side of cam to the distance and through-hole 21 of 2 bottom surface of cam need to be set, through-hole 21 arrives cam 2
The distance of bottom surface is the common height of required lifting workpieces 9, and the distance of through-hole 21 to 2 planar side of cam is that workpiece 9 reaches roller
Height on cylinder 5；
B, by 7 rotation cam 2 of extension bar, making cam 2 not is that the side of arc surface turns to the upper surface of bracket 1,
So that through-hole 21 is reached the height on roller 5 to the distance workpiece 9 of 2 planar side of cam, the workpiece 9 that need to be processed is placed in roller
On cylinder 5；
