Description
Technical field:
The present invention relates to be mainly used in a kind of ruler base that has bidirectional levelling instrument in the mechanical industry, particularly be applied in the heavy-duty machine form and position tolerance of products such as transit, spirit-leveling instrument measurement shield machine, bilateral scissors, vertical spindle coal pulveriser, military project and the measurement of absolute altitude.
Background technology:
At present, spirit-leveling instrument and transit are when measuring form and position tolerance or absolute altitude, must read the relative error of measured surface with the scale of good stability, also need scale that enough length is arranged sometimes, calculate morpheme error or absolute altitude by the relative error value of gathering each measurement point apart from optical reference plane.Can only cause image data accuracy and measuring speed all very low with the level of estimating the control scale or vertical before the present invention.Develop a kind of ruler base that has bidirectional levelling instrument is new problem anxious to be solved always.In order to improve scale bearing accuracy, measuring speed and expansion scale range, dwindle the uncertainty of measurement result, promptly solved the difficult problem of heavy workpiece form and position tolerance or level measurement, measured form and position tolerance, measured right alignment as transit and spirit-leveling instrument with the ruler base that has bidirectional levelling instrument; Transit survey linearity, flatness; Spirit-leveling instrument is measured linearity, flatness.The uncertainty of measurement result can both satisfy the measuring requirement of heavy workpiece form and position tolerance.Through measuring process practice and calculating, the uncertainty of its measurement result can be dwindled 30-80%, and has improved measuring speed.
Summary of the invention:
The purpose of this invention is to provide a kind of can all can the realization level accurately the location, increased substantially that heavy-duty machine, parts and workpiece form and position tolerance are measured or level measurement result's uncertainty, make the measuring method of spirit-leveling instrument and transit survey form and position tolerance more accurate, improve the standard and the bearing accuracy of vertical both direction, the ruler base that the assurance measurement result has bidirectional levelling instrument accurately different measured surfaces with vertical both direction.
The object of the present invention is achieved like this: the ruler base that has bidirectional levelling instrument, the principle of work of this device is the application level principle, the bidirectional levelling instrument ruler base of design in the horizontal direction, vertical direction all is provided with level, guarantees that horizontal direction, vertical direction image data are stable, accurately, fast.The designed product of principle of work that has the ruler base of bidirectional levelling instrument, three kinds of plane ruler bases, circular arc ruler base, V-type ruler base are arranged, plane ruler base measurement plane workpiece, the 2nd, circular arc ruler base measured hole class workpiece, the 3rd, the V-type ruler base is measured shaft-like workpiece; When the structure of design bidirectional levelling instrument ruler base, because scale folder in pedestal top is higher, be difficult in that the plane processes the groove that level is installed on the pedestal, therefore pedestal is divided into two parts, connect from the bottom with socket head cap screw, be convenient to adjust the level of level simultaneously; In order to guarantee the level installation accuracy, groove bottom is cast the arc identical with the level shape with gypsum, as fundamental plane is installed, puts into level then, and the adjustment level cements level admittedly with multi-purpose adhesive again, fills up the slit with gypsum at last; The design of the clamp groove of scale is installed, select slide calliper rule or pit gauge to make scale according to measuring needs as main scale, straight steel ruler etc., then, make the long limit of scale one side lean against one side of groove, to keep following measurement face or the slotted line place plane of scale perpendicular to pedestal; Then, with three pressing plates of six screw in compressions scale firmly is connected on the rear sight base and can measures; Because of the scale maximum length can reach 3000mm, can enlarge the range of scale again; Make measurement form and position tolerance kind more, the volume of measuring object is bigger; During measurement, adjust ruler base and make the bubble of level be positioned at the centre position, calculate morpheme error or absolute altitude according to the numerical value of gathering measurement point method in accordance with regulations.
Main points of the present invention are its principle of work and product design structure.Principle is used: its product structure is the application level principle design, and the bidirectional levelling instrument ruler base of design all is provided with level in level, vertical direction, guarantee horizontal direction, vertical direction image data accurately, fast, stable.Novel structure: the design of plane, circular arc and V-type ruler base and scale convertibility.Each ruler base all is with 3 little pressing plates, and the scale that will satisfy measurement requirement by screw is installed on the ruler base, can realize form and position tolerance and level measurement.The design and the manufacturing of the ruler base of band bidirectional levelling instrument, heavy workpiece form and position tolerance Measurement Uncertainty and measuring speed have been improved, and, also provide the reliable technique assurance for form and position tolerances such as the flatness of measuring large-scale workpiece with transit, spirit-leveling instrument, the depth of parallelism, right alignment, symmetries for the measurement of heavy workpiece form and position tolerance provides the auxiliary equipment of science.Band bidirectional levelling instrument ruler base has promotional value widely in industries such as heavy type, metallurgy, shipbuilding, motors.
Have the bidirectional levelling instrument ruler base compared with prior art, have good stability, simple in structure, the scope of application is extensive, workable, advantages such as technology good, low cost of manufacture, using method simple, high-level efficiency, will be widely used in the mechanical industry.
