Abstract
The utility model relates to the manufacture of mechanical instrument, in particular to an omnibearing digital electric gradienter applied to measure the gradient of the plane relative to the level at any direction. The top of the gradienter frame is provided evenly with three or more non-contact displacement sensors; a level induction plate is hung at the center of the frame, a hanging weight is hung below the level induction plate so as to keep the level induction plate in the natural level; the utility model is also provided with a data processing and display system to process the electric signal sent out by the sensor. The three displacement sensors can detect the obliquity of the frame relative to the level induction plate and the azimuth angle; thus the obliquity and the azimuth angle of the component relative to the level surface is detected. After the processing of level switch, A/D switch and optoelectronic insulation, the electric signal sent out by the non-contact displacement sensors can be delivered to the micro-processor to process the digital signal; thus, the micro-processor displays the obliquity and the azimuth angle in the form of digital.
Description
Affiliated technical field
The utility model relates to machinery instrument and manufacturing, refers in particular to be used for measurement plane in any direction with respect to a kind of comprehensive digital electronic level meter of inclined degree.
Background technology
Traditional level meter kind has frame level, pincers worker level meter and image bonding level, they all with level as measuring and the reading element.Level is a sealed glass pipe, and the less liquid of the coefficient of viscosity is housed in the pipe, does not have the part of liquid, is called leveling bubble; We claim that traditional level meter is a bubble type level meter.The unevenness that bubble type level meter mainly relies on the side-play amount in bubble skew level centre position to come a certain zone, measuring workpieces surface.Its defective is: bubble type level meter is very sensitive to temperature, and along with the rising of temperature, bubble length changes, and the size of bubbler tube inner chamber also changes, and causes the apparatus measures error to increase; Secondly, whether each workplace of bubble type level meter will will come the zero-bit of determined level instrument accurate according to the position of bubble before use, and can only measure the horizontality of limited direction; Moreover whether tested planar horizontal obtains by eyes observation leveling bubble departure degree relative and zero-bit, has ambiguity.From the patent retrieval situation, still there is not the report of this kind patent at present.
Summary of the invention
In order to overcome the deficiency that traditional bubble type level measurement is coarse and zeroing is loaded down with trivial details, the utility model provides a kind of comprehensive digital electronic level meter, this level meter has overcome the deficiency of traditional level meter, directly read the orientation at definite pitch angle of measurand and place on the Displaying Meter of can be directly joining from electrolevel, and simplified the zeroing process greatly.
The technical scheme that the above-mentioned technical matters that realizes the utility model adopts is: at the even non-contact displacement transducer that distributes more than three or three in the top of level meter framework, horizontal tablet of framework central mounting, it is heavy that an extension is hung in horizontal tablet below, to guarantee horizontal tablet nature level, simultaneously, data processing and display system is set, the electric signal that processes sensor is sent.
During measurement, level meter is placed on the surface of measured workpiece, because the out-of-level degree on measured workpiece surface makes framework produce, inclination angle between horizontal tablet and the framework also changes, can measure framework with respect to the inclination angle of horizontal tablet and the position angle of inclination by three displacement transducers, thereby measure measured workpiece inclination angle and well azimuth with respect to the horizontal plane.The electric signal that non-contact displacement sensor can be induced for supplying the digital signal of microprocessor processes, provide the position angle of angle of inclination and inclination by treatment conversion such as level conversion, A/D conversion, photoelectricity isolation with the form of numeral demonstration by microprocessor processes.
