Description
Technical field
The utility model relates to metering field, particularly relates to a kind of inner diameter measuring device for measuring workpieces internal diameter.
Background technology
Inner diameter measurement instrument is widely used in field of machining, and existing inner diameter measurement instrument is all hand-held, and the meter that namely needs gauger hand-held carries out the inner diameter measurement of the objects such as workpiece, and therefore, traditional inner diameter measurement instrument also exists following defect:
1, metric data accuracy is low: during measurement, the gimmick of different measuring person is different, and measuring the data obtained also can be inconsistent;
2, metric data poor stability: data-bias is comparatively large, and meter corrected value is easily run away, and needs again to make zero and remeasure;
3, operation is very inconvenient: need to measure by platform or fixed part, easily cause erroneous judgement.
Utility model content
The technical problems to be solved in the utility model, provides a kind of inner diameter measuring device, for improving the accuracy of operating inner diameter measurement and measuring simple operation.
The utility model is achieved in that
A kind of inner diameter measuring device, comprise percentile scale, described percentile scale comprises rotating scale dial plate, push rod, fixed bar and gage button, described push rod and fixed bar are arranged at the two ends of the axis of symmetry of rotating scale dial plate, pointer interlock on push rod and rotating scale table, described inner diameter measuring device also comprises scale base;
The bottom of described scale base is provided with support column, the upper surface of scale base offer with described rotating scale dial plate bottom suitable scale fixed groove, the bottom of described rotating scale dial plate is embedded in described scale fixed groove, push rod and gage button are placed in the upper surface of scale base, and the periphery of described scale holder is provided with the placement platform for placing determinand.
Wherein, the bottom of described scale base offers screw, and described support column is the bolt suitable with described screw, and the height of described bolt is greater than the degree of depth of screw.
Wherein, support column described at least one is arranged with square weightening finish block.
Wherein, hold-down nut is provided with between the lower surface of described scale base and described bolt.
Wherein, the bottom supported described in is provided with rubber mat.
The utility model tool has the following advantages: the placement platform that workpiece to be measured can be positioned over scale base by this inner diameter measuring device is measured, therefore can measure under same benchmark, avoid the error caused because of the angle difference of the hand-held meter of operator, improve the consistance of measurement, and, workpiece only need be positioned on placement platform and can measure when measuring by this measurement mechanism, practicality is high, in workshop etc. without can operate when platform in the same old way, this measurement mechanism can be used for the workpiece measuring different-thickness, and measurement range is wide.

Embodiment
By describing technology contents of the present utility model, structural attitude in detail, realized object and effect, accompanying drawing is coordinated to be explained in detail below in conjunction with embodiment.
Refer to Fig. 1 and Fig. 2, this inner diameter measuring device comprises percentile scale, described percentile scale comprises rotating scale dial plate 21, push rod 23, fixed bar 22 and gage button 24, described push rod 23 and fixed bar 22 are arranged at the two ends of the axis of symmetry of rotating scale dial plate 21 respectively, the pointer interlock on push rod 23 and rotating scale table 21.Push rod described in present embodiment (or being called motion bar), fixed bar and gage button are identical with the functions and principles of the motion bar in existing inner diameter measurement dial indicator, fixed bar and gage button, and described inner diameter measuring device also comprises scale base in the present embodiment;
The bottom of described scale base is provided with support column 34, the upper surface of scale base offer with described rotating scale dial plate bottom suitable scale fixed groove 32, the bottom of described rotating scale dial plate 21 is embedded in described scale fixed groove 32, push rod 23 and gage button put 24 in the upper surface of scale base, and the periphery of described scale holder is provided with the placement platform 31 for placing determinand.
In this inner diameter measuring device push rod 23 and the position arranged described in fixed bar 22 and existing dial bore gage different, in this inner diameter measuring device, push rod and fixed bar are arranged at the two ends of the axis of symmetry of rotating scale dial plate respectively, and the bottom of described rotating scale dial plate is embedded in described scale fixed groove, the periphery of scale holder is provided with the placement platform for placing determinand, therefore, only workpiece to be measured need be positioned on described rotation platform, then can the internal diameter of workpiece be measured by the flexible length of adjustment push rod.With compared with the dial bore gage had, this inner diameter measuring device not only maintains the measuring accuracy of existing dial bore gage, and this inner diameter measuring device measure time without the need to hand-held measuring equipment and workpiece for measurement, all workpiece are all based on same benchmark when measuring, measurement mechanism is consistent with the relative position relation of measuring workpieces, there is high measurement consistance, simultaneously, this inner diameter measuring device is simple to operate, workpiece only need be buckled and be put on placement platform by operating personnel, and this device practicality is high, in workshop etc. without can operate when platform in the same old way, popularization is good, no matter workpiece thickness size can be suitable for.
Further, the bottom of described scale base offers screw 33, and described support column 34 is the bolt suitable with described screw, and the height of described bolt is greater than the degree of depth of screw.
Therefore, not only can be adjusted the height of scale base by described bolt, meanwhile, also the levelness ground of adjustable scale base, ensures inner diameter measurement precision.
Certainly, this inner diameter measuring device also can adopt and be fixed on support column, and namely support column is the bottom being directly welded in scale base.
Further, in order to reduce the center of gravity of this inner diameter measuring device, this device being placed there is higher stability, support column described at least one being arranged with square weightening finish block 36.
In one embodiment, in order to improve the connective stability between described bolt and scale base, between the lower surface of described scale base and described bolt, be provided with hold-down nut 35.
In one embodiment, in order to eliminate the impulsive force produced when workpiece is positioned over placement platform, described in the bottom that supports be provided with rubber mat 37.
The foregoing is only embodiment of the present utility model; not thereby the scope of the claims of the present utility model is limited; every utilize the utility model instructions and accompanying drawing content to do equivalent shapes or Structural Transformation; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present utility model.
