Description
Technical field
The present invention relates to field of measuring technique, especially relate to a kind of level meter.
Background technology
Level meter is the low-angle conventional measurer of a kind of measurement.In machinery industry and instrument manufacture, for measuring the horizontal level installed relative to the pitch angle of horizontal level, the flatness of lathe kind equipment guide rail and linearity, equipment and upright position etc.Can be divided into by the profile difference of level meter: Universal level-metre, cylinder level meter, integrated water level, mini level meter, camera level meter, frame level, chi formula level meter; Can be divided into again by the fixed form of level: adjustable water level and can not mode level meter.
The level tube of level meter is made up of glass, and level tube inwall is a curved surface with certain curvature radius, and pipe is built with liquid, and when level meter run-off the straight, one end that in level tube, bubble just raises to level meter is moved, thus determines the position of surface level.Level tube inwall radius-of-curvature is larger, and resolution is higher, and radius-of-curvature is less, and resolution is lower, and therefore level tube radius-of-curvature determines the precision of level meter.Level meter is mainly used in the horizontal level etc. checking the flatness of various lathe and workpiece, linearity, verticality and equipment to install.Particularly survey verticality time, magnetic water level can absorption on vertical operation face, manually need not help, alleviate labour intensity, avoid human heat's radiation belt to the measuring error of level meter.
Level meter is mainly used in the linearity of the various lathe of inspection and other type equipment guide rail and the horizontal level of equipment installation, upright position.It also can be applied to low-angle measurement and the workplace with V-type groove, also can measure the installation depth of parallelism of cylindrical workpiece, and install horizontal level and upright position.
Present level meter does not carry out the function of range observation; A lot of place all needs the measurement carrying out distance; Such as in Railway System: train manufacture, auto-control improve, detect rail levelness etc.; Water conservancy system: dam detection etc.; Automobile industry: four-wheel aligner, road surface control, engineering truck leveling etc.; The level condition of mechanical scanning, lathe and skiver's station and position; The angle of pitch of building engineering equipment, roll angle and pitch angle, road administration bridge slope detection etc.
Angularity, for stating plane degree of crook in space, is numerically defined as warpage plane in the height direction apart from the distance of point-to-point transmission farthest.The angularity of fully-flattened is 0.
Buckling deformation is one of important indicator of evaluation product quality.In existing appraisement system, buckling deformation evaluation is all undertaken by amount of warpage, generally evaluate by the buckling deformation amount of maximum buckling deformation amount or specific part.When present employing injection moulding CAE carries out designing quality prediction, undertaken by maximum buckling deformation amount the evaluation of buckling deformation analog result is generally direct, sometimes also using the index of the statistics such as the average amount of warpage of overall average buckling deformation amount, 10% maximum buckling deformation node as evaluation buckling deformation.
During identical product for identical Warping Effect pattern, these indexs can describe the size degree of the buckling deformation of different designs.But for the factor that different materials, mould structure etc. cause the Effect Mode of buckling deformation to change, under different designs, the buckling deformation order of severity of each several part also changes thereupon.Now evaluate buckling deformation by maximum buckling deformation amount or other relative statistic amount and there is larger limitation, the users satisfaction degree of product buckling deformation when better can not embody different designs.Particularly for complex parts, there is significant limitation in the buckling deformation characterizing goods by maximum buckling deformation or other statistic.
Now neither be very convenient for the measurement of angularity; General employing angularity measuring instrument, realizes the measurement to angularity; Angularity measuring instrument carries inconvenience, and expensive price; Be inconvenient to carry with use; General is all that angularity measuring instrument of being taken by the article that band is measured is measured; Mode is single, and inconvenience very in operation.
