Embodiment
Below in conjunction with drawings and Examples, the technical solution of the utility model is described in detail.
With reference to Fig. 1, before by 1 installation of centering equipment, first utilize ordinary level 2 on its levelness installed surface, to select four or more measurement point, then utilize micron micrometer measurer 3 of the present utility model to measure the actual elevation of each measurement point, and the equipment that calculates install after the difference of actual elevation and designed elevation, and ensure that this difference is within the code requirement of design standards and equipment installation.
With reference to Fig. 2, the utility model is for the micron micrometer measurer 3 of large-scale precision equipment centering, and its component parts comprises with the special Sopwith staff 32 of millimeter scale and is arranged on described special Sopwith staff 32 and forms the milscale head 31 of sliding motion pair with described special Sopwith staff 32.
With reference to Fig. 3, Fig. 4, described milscale head 31 is the positive hollow cylinder that has window 311, described window 311 places are set to the down scale chi 312 that scale value is 0.99mm, described milscale head 31 is symmetrical in the upper of its radial center both sides, a pair of dog screw 313 is equipped with respectively in lower end, described dog screw 313 is for ensureing that described milscale head 31 is with respect to described special Sopwith staff 32, when lower slider, do not produce and rotate, and make its accurate positioning, described milscale head 31 1 sides upper, between lower two dog screws 313, gib screw 314 is housed, described gib screw 314 is fixed on described milscale head 31 on described special Sopwith staff 32 and is convenient to reading when measuring.
With reference to Fig. 5, Fig. 6, described special Sopwith staff 32 is for being provided with the hollow cylinder of millimeter scale on it, the radial center symmetria bilateralis of described hollow cylinder is processed with sliding channel 321, on the width of described sliding channel 321 and described milscale head 31, the diameter of dog screw 313 agrees with mutually, so that described milscale head 31 forms sliding motion pair by the mating reaction of described dog screw 313 and described sliding channel 321 and described special Sopwith staff 32, and on described special Sopwith staff 32, realize position by described gib screw 314 and fix.
For the ease of installed height mark and the levelness centering of main equipment, the measurement length that the utility model arranges described special Sopwith staff 32 is 1500mm.
The measuring method that the utility model coordinates ordinary level to carry out main equipment installation level centering comprises the steps:
