Detailed description of the invention:
A kind of high-accuracy water leveling ruler assay device based on sine, as it is shown in figure 1, by detection platform 1, pedestal 3, detection platform 1 is connected with pedestal at one end through rotary shaft 5, and below described pedestal, surrounding is four levelling foots 7, can be adjusted the levelness of detection platform 1 and pedestal 3.Detection platform 1 can be to rotate upwardly and downwardly by rotary shaft 5;The other end of detection platform 1 and pedestal 3 is connected by adjusting nut 6, rotates adjusting nut 6 and detection platform can be made to rotate upwardly and downwardly;In described detection platform, the side near adjusting nut is fixed with displacement transducer 2, the upper surface of the gauge head contact pedestal 3 of displacement transducer 2, the measuring staff axial line distance of the displacement transducer 2 axle center 1m away from rotary shaft 5.
As in figure 2 it is shown, have for fixing tested horizon rule pressing plate and support 4 in described detection platform 1, gauge 11 is fixed on detection platform 3 by screw, and having air level 10, described detection platform 3 in the middle part of described detection platform 3 is locating piece 8 near rotary shaft 5 side;
As shown in Figures 3 and 4, accessory has 45 ° of location bars and 90 ° of location-plates, has screw 13 in detection platform side, fixing for 45 ° of location bars 14, and there is screw 16 detection platform and pedestal side, fixing for 90 ° of location-plates 15.
As shown in Figure 6, displacement transducer 2 can be connected with computer 18 by data wire 17.
This utility model is as follows for the mode of horizon rule calibrating:
(1) leveling of the present utility model
Such as Fig. 3, during use, first regulation levelling foot 7, rotating adjusting nut 6 again, until the spirit bubble 10 in detection platform 1 is stable in center, it is ensured that the level of detection platform 1 self, then displacement transducer 2 is returned to zero, being placed on horizon rule assay device by tested horizon rule 12 afterwards, the side of horizon rule is critical by locating piece 8, is finally fixed with pressing plate 4.
