Abstract
The utility model provides a prism centering rod calibrator, including the annular clamped board and the tripod of fixing terminal surface under the fixed plate, being provided with bearing frame and bearing on the fixed plate, the bearing frame is fixed on the fixed plate through three evenly distributed's adjusting bolt, and the bearing internal fixation has the hollow shaft. The beneficial effects of the utility model are that: the utility model has the advantages of simply, easy operation, the calibration is quick, the calibration accuracy is high.
Description
Technical field
The invention belongs to ergonomic measuring tool field, particularly relate to a kind of prism centering rod aligner。
Background technology
Along with Modern Surveying & Mapping scientific technological advance, micrometer instrument is replaced by electronic total station (total powerstation) gradually, with the matching used prism centering rod of total powerstation because the features such as its light practicality obtain extremely using widely。But centering rod whether tilt relationship is to the precision of measurement result, traditional calibration steps needs collocation total powerstation, operate very loaded down with trivial details, not easily operates, and the many people of need have coordinated out of doors。
Utility model content
The purpose of this utility model be in that to provide a kind of simple, easily operation, calibration quickly, calibration accuracy height only need 1 people, the prism centering rod calibrator (-ter) unit that indoor and outdoor all can carry out。
This utility model is realized by following measure: a kind of prism centering rod aligner, including ring-type fixing plate and the spider being fixed on described fixing plate lower surface, described fixing plate is fixed with bearing block and bearing by three equally distributed adjusting bolts, in described bearing, is fixed with hollow axle。
Wherein, between the peripheral described bearing block of described adjusting bolt and described fixing plate, it is provided with spring。
Described hollow axle sidewall is provided with at least 3 bolts hole, is equipped with fixing bolt in described bolt hole。
The upper surface of described fixing plate is provided with a blind hole, installs circle blister in described blind hole。
The beneficial effects of the utility model are: the advantage that this utility model has operation simple, easy, calibration is quick, calibration accuracy is high, wherein, bearing block is movably fixed on fixing plate through circular hole conveniently regulates prism centering rod by the adjusting bolt mated with bolt hole is kept plumbness, makes operation quickly and easily change；During calibration, prism centering rod is fixed on hollow axle by fixing bolt, it is ensured that during calibration, centering rod is followed hollow axle and rotated together, need not individually rotate centering rod, and influencing each other when reducing calibration operation increases calibration accuracy；The arrangement of circle blister on fixing plate, is conducive to observing and adjust spider in time and is in level, make calibration operation more quick, owing to not needing total powerstation, only need one man operation, therefore indoor also can be calibrated work。

Detailed description of the invention
For the technical characterstic that this programme is described can be known, below by detailed description of the invention, this programme is illustrated。
Referring to Fig. 1, Fig. 2 and Fig. 3, this utility model is a kind of prism centering rod aligner, including ring-type fixing plate 1 and the spider being fixed on fixing plate 1 lower surface, fixing plate 1 is provided with bearing block 2 and bearing 3, bearing block 2 is fixed on fixing plate 1 by three equally distributed adjusting bolts 5, hollow axle 4 it is fixed with in bearing 3, it is provided with spring 8 between the peripheral bearing block 2 of adjusting bolt 5 and fixing plate 1, hollow axle 4 sidewall is provided with at least 3 bolts hole, fixing bolt 6 it is equipped with in bolt hole, the upper surface of fixing plate 1 is provided with a blind hole, circle blister 7 is installed in blind hole。Spider 1.2 meters that diameter can be adopted to be 10mm and each 3 of 1.5m round bar make, during making, one end of 3 1.2 meters of round bars every is uniformly fixed on fixing seat, forming three frame lower limbs of spider, 3 1.5 meters round bar every all transverse horizontal are fixed between the every two frame lower limbs of spider。
When prism centering rod is calibrated, spider is maintained static, observe circle blister 7, when spider level, after prism centering rod is inserted down from hollow axle 4, tighten fixing bolt 6, prism centering rod is fixed, adjust adjusting bolt 5, make circle level(l)ing bubble placed in the middle, then rotate hollow axle 4 and drive centering rod to rotate 180 °, if bubble is not placed in the middle, then the calibration screw adjusted bottom circular bubble makes bubble move the half of offset distance to middle position。This method should be repeatedly performed 2～3 times, until centering rod forwards any position to, till bubble is all placed in the middle。All must first adjust adjusting bolt 5 before it should be noted that calibration every time makes circle level(l)ing bubble placed in the middle, observes the position of bubble after then again centering rod being rotated 180 °。
This device does not need total powerstation, and flexible operation is simple, time-consuming few, it is only necessary to 1 people, and indoor and outdoor all can carry out, and is particularly suitable for the calibration not having the single pair of king-rod of leg。
This utility model can pass through without the technical characteristic described or adopt existing techniques in realizing; do not repeat them here; certainly; described above is not to restriction of the present utility model; this utility model is also not limited to the example above; the change made in essential scope of the present utility model of those skilled in the art, remodeling, interpolation or replacement, also should belong to protection domain of the present utility model。
