As further improvement of the utility model, described top stop and be along the reference seat structure being positioned in reference seat of radially can sliding in the z-direction, be provided with a cover plate, described cover plate is fixedly connected with reference seat, top is closely located between cover plate and reference seat, cover plate is provided with hollow hole, top top just and this hollow hole position just right.
As further improvement of the utility model, on described cover plate, hollow hole is that top one end opening diameter is greater than the bellmouth orifice towards top one end opening diameter dorsad, and the hollow hole top diameter that is greater than top towards top one end opening diameter.
As further improvement of the utility model, the quantity of described jacking block is two groups, is symmetrically distributed in respectively top surrounding, and four jacking blocks are tight against respectively top surrounding sidewall.
As further improvement of the utility model, described top contacts by the inclined-plane mutually mating with jacking block.
As further improvement of the utility model, the inclined-plane of described jacking block is pressed on top inclined-plane reference seat one side dorsad.
As further improvement of the utility model, be also provided with drive unit, described drive unit is positioned on the sidewall of reference seat, and each drive unit is corresponding with each jacking block position respectively, and drive unit can drive respectively each jacking block to slide.
As further improvement of the utility model, described drive unit is the one in pin and double-screw bolt.
Useful technique effect of the present utility model is: the utility model heads on top by jacking block and move along two orthogonal directions the fine setting of carrying out top shaft core position in reference seat, and then realize top with main shaft two bearings shelves cylindrical concentricity up to standard, it is simple in structure, easy to operate, can be used for emery wheel reference for installation: 1:5 on two bearings shelves cylindrical on grinding spindle, emery wheel reference for installation 1:30 cone cylindrical, bistrique tapered sleeve and bore cylindrical etc., highly versatile, is convenient to processing and manufacturing.
