Abstract
The utility model relates to a sensitive luminous measuring rod, which comprises a measuring base rod, a measuring head, a measuring rod, a differential measuring head, a battery and a light emitting diode. The sensitive luminous measuring rod can be used for precision distance measurement on various occasions, and is particularly suitable for point-contracting measurement. For example, the centre lines of bearing holes of a low-pressure cylinder and a bearing box must be in the same line during the assembling process of the turbine low-pressure cylinder and the corresponding bearing box. Fine steel wires are used as auxiliary lines of the centre lines generally, and the positions of the low-pressure cylinder and the bearing box are adjusted based on the auxiliary lines so as to ensure the assembling accuracy. The sensitive luminous measuring rod can measure the distance between the circumference of each bearing hole and each fine steel wire accurately and conveniently.
Description
Technical field the utility model belongs to the auxiliary mould device in equipment manufacturing field, relates to a kind of auxiliary mould device that is used for to rat holing in the equipment manufacturing specifically.
Background technology needs accurately to measure a line or some distance somewhither in equipment manufacturing field sometimes, and traditional method typically uses micrometer inside caliper and measures.The advantage of this measurement is to use easier instrument to carry out very accurate measurement, the distance that can two planes of fine measurement or the internal diameter in hole.But when the place in tested two places or two places were line or some, there was a very big defective in this method.Because measuring head and tested point are all very little, are difficult to whether contact with measuring point, thereby have reduced measuring accuracy by the visual determination sounding rod.
In order to address the above problem, the utility model utilizes light emitting diode to judge the survey instrument whether sounding rod has contacted with measuring point.Thereby well solved this problem when not having undue increase cost again.When using micrometer inside caliper or sounding rod in some cases in order to remedy, summary of the invention the utility model is difficult for judging that whether milscale contacts with measuring point develops.
Concrete technical scheme of the present utility model is:
The utility model is to comprise that by sounding rod measuring head, sounding rod A, sounding rod B etc. are (according to different situations, select different sounding rods, not necessarily two), measure basic bar, light emitting diode, battery, differential measurement head, finer wire, sounding rod, bearing housing, low pressure (LP) cylinder, bearing housing and form, it is characterized in that: as required, use different sounding rods to plug into and become to be slightly less than measurement of length bar to be measured; Use the differential measurement head that the length of sounding rod is finely tuned during measurement; When on the sounding rod during lumination of light emitting diode, stop the adjusting of differential measurement head, be normal measurement state this moment, and reading at this moment is the size of measuring.
Need to prove: the principle of this sounding rod utilization is the principle that electric current makes led lighting, requiring sounding rod all is to make of conductor, and to be measured also must be that (overwhelming majority in the equipment manufacture needs the workpiece of precision measurement all to be made of metal to conductor.) when sounding rod two ends measuring head contacted with workpiece, battery, diode, sounding rod, workpiece constituted the loop, have electric current to pass through led lighting in the circuit thereby make.
The utility model makes measuring process more simplify, and has improved the precision of measuring greatly.
Description of drawings
Fig. 1 is the sounding rod wiring layout;
Fig. 2 is the sounding rod part drawing;
Fig. 3 is sounding rod operation instruction figure;
Fig. 4 is the dead eye enlarged drawing.
Embodiment as the utility model as described in Fig. 1, Fig. 2, Fig. 3, Fig. 4 by the measuring head 1 of plugging into, the sounding rod A2 that plugs into, measure basic bar 3, light emitting diode 4, battery 5, the sounding rod B6 that plugs into, the differential measurement bar 7 of plugging into, finer wire 8, sounding rod 9, bearing housing 10, low pressure (LP) cylinder 11, bearing housing 12 and form, its essential characteristic is: Fig. 1 is the sounding rod wiring layout, light emitting diode 4 is placed the groove of measuring basic bar 3, make the good two ends of being fixed in groove of two-stage contact of diode; Battery 5 is placed in the basic bar 3 of measurement; The sounding rod 2,6 etc. of plugging into as required; Termination at sounding rod is refuted measuring head 1; At the other end differential measurement bar 7 of plugging into.
Fig. 3 is used for the key diagram of steam turbine mesolow cylinder and bearing housing assembling process for this sounding rod.The matching requirements of low pressure (LP) cylinder 11 and bearing housing 10,12 are: three's center line must be at same straight line.Now done a boost line of representing center line with finer wire 8.Measure the distance of the circumference of each dead eye with sounding rod 9, adjust the relative position of low pressure (LP) cylinder, bearing housing and steel wire then according to the result, up to reaching matching requirements to center line.
