Abstract
The utility model discloses a guide rail dovetail face parallel degree measuring apparatus. The apparatus comprises an L type support, a guiding shaft, a supporting rod, a steel ball and a dial gauge. The guiding shaft is fixed on one side of the support. The axial direction of the guiding shaft is parallel to a measured guide rail dovetail face. The supporting rod is connected with one end of the support. The other end of the supporting rod is connected with the steel ball. The dial gauge is fixed on the supporting rod. The end face of the measuring rod of the dial gauge is a spherical face. The apparatus can detect the guide rail dovetail face in a rapid and accurate way.
Description
Technical field
The utility model relates to field of measuring technique, is specifically related to a kind of measurement mechanism of the guide rail dovetail face depth of parallelism.
Background technology
Fig. 1 is the check rod mensuration of a dovetail guide and the depth of parallelism thereof, the long 800mm of dovetail guide, and the depth of parallelism of dovetail face requires to be less than 0.03mm in total length.Check rod mensuration is to be placed on dovetail both sides with the pole of two equal diameters, with miking size L, and mobile check rod in guide rail total length, a plurality of values that can L, its maximal value and minimum difference on duty are the parallelism error of dovetail face.Although this measuring method is simple, is subject to not affecting on an equal basis of check rod circularity and straightness error and ergometry, measuring accuracy is not high.
Summary of the invention
For above-mentioned technical matters, the purpose of this utility model is to provide a kind of measurement mechanism of the guide rail dovetail face depth of parallelism, and the utility model can detect guide rail dovetail face fast and exactly.
The technical scheme that realizes above-mentioned purpose is as follows:
The measurement mechanism of the guide rail dovetail face depth of parallelism, comprise the support, the axis of guide, cramp bar, steel ball and the clock gauge that are L-type, the axis of guide is fixed on a side of support, the axis of guide axially parallel with tested guide rail dovetail face, cramp bar is connected with one end of support, the other end of cramp bar is connected with steel ball, and clock gauge is fixed on cramp bar, and the end face of the measuring staff of clock gauge is sphere.
Adopted such scheme, while using the utility model to measure dovetail face, the axis of guide has been leaned against on a side rails, adjusted clock gauge, made it there is suitable ergometry, and adjusted dial plate and make pointer nulling.Then enforce lightly cubing and move along a side rails, and keep steel ball to contact with guide rail surface level, observe noon submeter indicating value and change, the maximum algebraic difference of indicating value is parallelism error.The utility model can quick, conveniently also detect guide rail dovetail face exactly.
Described cramp bar is provided with the regulating tank along its short transverse, and the measuring staff of clock gauge is through this regulating tank.By regulating tank, can make the measuring staff of clock gauge along regulating tank upper and lower displacement, guarantee that measuring staff contacts with guide rail dovetail face.
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Accompanying drawing explanation
Fig. 1 measures the schematic diagram of dovetail guide in prior art;
Fig. 2 is structural representation of the present utility model;
In accompanying drawing, 1 is that support, 2 is that the axis of guide, 3 is that cramp bar, 4 is that steel ball, 5 is clock gauge.
Embodiment
With reference to Fig. 2, the measurement mechanism of the guide rail dovetail face depth of parallelism of the present utility model, the measurement mechanism of the guide rail dovetail face depth of parallelism, comprise the support 1, the axis of guide 2, cramp bar 3, steel ball 4 and the clock gauge 5 that are L-type, the axis of guide 2 is fixed on a side of support, the axis of guide 2 axially parallel with tested guide rail dovetail face, cramp bar 3 is connected with one end of support 1, the other end of cramp bar 3 is connected with steel ball 4, and clock gauge is fixed on cramp bar, and the end face of the measuring staff of clock gauge is sphere.Described cramp bar is provided with the regulating tank along its short transverse, and the measuring staff of clock gauge 5 is through this regulating tank, and clock gauge 5 is along this regulating tank energy upper and lower displacement.
