Embodiment
Below in conjunction with drawings and Examples, embodiment of the present utility model is described in further detail.Following examples are used for illustrating the utility model, but are not used for limiting scope of the present utility model.
As shown in Figure 1-2, cross slide way 2 is slidably connected in the pilot hole 4 on V-type bracing frame 5 tops, and cross slide way 2 one end are connected with measures indicator 1, measures indicator 1 and is removably connected with digital display meter head 3, measures the vertical setting of indicator 1 and measuring junction downward; In the time that measurement indicator 1 is worn, only need to change and measure indicator 1, digital display meter head 3 still can continue use, cost-saving.V-type bracing frame 5 bottoms are arranged with at least two supporting legs 6 about measuring indicator 1, have certain angle between supporting leg 6, whole measurement mechanism can be fixed to axletree to be measured surface.Whole V-type bracing frame 5 has certain width along pilot hole 4 length directions, can fully ensure stability when measurement mechanism is fixing on axletree to be measured surface, ensures that the center line of measurement indicator 1, through the center of circle of axletree to be measured, ensures to measure accurately.
As in Figure 3-5, pilot hole 4 one sides have width measure groove, and the length direction of width measure groove is identical with the length direction of pilot hole 4, and width measure groove is communicated with pilot hole 4, the convenient displacement of cross slide way 2 in pilot hole 4 of observing from the side; When production, should on cross slide way 2, print scale mark, and in the edge of width measure groove, suitable scale mark is set, conveniently read the transverse shifting distance of cross slide way 2.Supporting leg 6 inner sides and axletree solution of contiguity to be measured are fluted, are provided with copper billet 7 in groove, softer because of the quality of copper, in measuring process, can avoid axletree by supporting leg 6 scratches.
As shown in Fig. 6-7, cross slide way 2 one end are connected with contiguous block 8, and contiguous block 8 middle parts are provided with the mounting hole 9 vertically running through, and mounting hole 9 one side at right angle setting hole 9 directions are provided with fixed orifice 10, and fixed orifice 10 is communicated with mounting hole 9; Measure indicator 1 and be connected on contiguous block 8 by mounting hole 9, thereby realize and being connected of cross slide way 2, in fixed orifice 10, be connected with bolt, the height and position for fixation measuring indicator 1 in mounting hole 9, ensures the true, accurate of measurement data.
Angle between supporting leg 6 is preferably 90 degree, and copper sheet width is tried one's best wider, makes V-type bracing frame 5 can realize the measurement to different-diameter axletree.
When production and processing, measure indicator 1 and adopt slim-lined construction, indicator material adopts tool steel, and carries out Quenching Treatment; After each parts machining completes, each corner angle are carried out to round and smooth processing, avoid in measuring process as far as possible, survey instrument causes scratch again or damage to axletree; Cross slide way 2 and pilot hole 4 clearance fit, require cross slide way 2 to slide in the interior gapless of pilot hole 4, and cross slide way 2 is in moving process, and connecting one end of measuring indicator 1 can not rock, in order to avoid affect measurement data.
When measurement, measurement mechanism is placed on axletree to be measured, makes axletree to be measured be stuck in supporting leg 6 inner sides, now axletree to be measured surface only contacts with the copper billet 7 of supporting leg 6 inner sides, can be by supporting leg 6 scratches; The height of adjustment measurement indicator 1, makes to measure the measuring junction of indicator 1 and the not blemish surface of axletree contacts, and tightens the bolt in fixed orifice 10, then by digital display meter head 3 zero clearings; Along slowly traverse measurement indicator 1 of pilot hole 4 length directions, the degree of depth of recording defect and width.In the time that the demonstration of digital display meter head 3 starts to change, record cross slide way 2 scale values corresponding to scale mark on width measure groove; In the time that the displayed value of digital display meter head 3 recovers normal, again record cross slide way 2 scale values corresponding to scale mark on width measure groove, the difference of twice scale value is the width of defect part, and the maximal value of digital display meter head 3 is the depth value of defect.
As can be seen from the above embodiments, the utility model, by adopting V-type bracing frame 5, can be realized the fixing fast of measurement mechanism, ensures the accuracy of measurement data; Measure indicator 1 and can realize the measurement to depth of defect with the combination of digital display meter head 3; Cross slide way 2 is provided with scale value, and width measure groove is convenient to observe and record the scale value on cross slide way 2, can realize the measurement to defect width.Measure indicator 1 by utilization and contact with fault location, then traverse measurement indicator 1, by the displacement of digital display meter head 3 numerical value change and cross slide way 2, obtains depth of defect and width numerical value.
Axletree surface tear defectoscopy apparatus structure described in the utility model embodiment is simple, cost is low, volume is little, can carry out portable operation, improve axle of motor train unit surface imperfection measuring accuracy and in, improved overhaul efficiency.Measure indicator 1 and removably connect with digital display meter head 3, when measuring after indicator 1 wearing and tearing, can change in time, without changing together with digital display meter head, cost-saving.Supporting leg 6 inner sides are equipped with copper billet 7, can ensure that in measuring process, axletree can not scratch or scratch by measured instrument.
The above is only preferred implementation of the present utility model; should be understood that; for those skilled in the art; do not departing under the prerequisite of the utility model know-why; can also make some improvement and replacement, these improvement and replacement also should be considered as protection domain of the present utility model.
