Description
技术领域technical field

背景技术Background technique
目前实验条件下轮轨力应变片的定位主要依靠尺子铅笔等简易工具进行手工定位，由于测试轮轨力的应变片对位置精度要求较高，而手工粘贴需要用直尺测量距离，画出粘贴位置等步骤，在此过程中难免出现位置误差，导致最终测试结果不准，在此背景下设计出了这一轮轨力应变片快速精准定位装置。Under the current experimental conditions, the positioning of wheel-rail force strain gauges mainly relies on simple tools such as rulers and pencils for manual positioning. Since the strain gauges for testing wheel-rail force have high requirements for position accuracy, and manual pasting requires a ruler to measure the distance and draw a paste Positioning and other steps, position errors will inevitably occur during the process, resulting in inaccurate final test results. Under this background, this fast and accurate positioning device for wheel-rail force strain gauges is designed.
传统应变片粘贴过程粘贴效率低下，步骤繁琐，精度较低，对于应变片的精准定位粘贴并无特别的设计。因此，传统过程需要耗费更多的人力和时间，得到的测试结果却并不一定准确。The pasting process of traditional strain gauges is inefficient, with cumbersome steps and low precision. There is no special design for the precise positioning and pasting of strain gauges. Therefore, the traditional process requires more manpower and time, but the test results obtained are not necessarily accurate.
本发明就是针对此问题对轮轨力应变片的快速精准定位设计了特殊装置。因而能保证应变片的快速、高效、准确地粘贴在钢轨上，从而提高测试精度，减少工作时间。The present invention designs a special device for fast and accurate positioning of the wheel-rail force strain gauges for this problem. Therefore, it can ensure that the strain gauges are pasted on the rail quickly, efficiently and accurately, thereby improving test accuracy and reducing working time.

The calibration plate has a shape structure consistent with the rail waist and rail bottom of the tested wheel and rail. The calibration plate is consistent with the tested wheel and rail. Calibration holes are provided at the corresponding positions of the rail waist and rail bottom items; centering holes 13 are provided in the middle of the bottom surface of the calibration plate for observation and positioning to realize the correct placement of the calibration plate; Snap-on mechanism 30 for plate coupling.
卡扣机构位于轨头正上方，实际使用时，将本装置安置于需要标定的钢轨上，通过对中孔找到两扣件间中心位置后，沿标定孔轮廓画出定位框，沿画线槽口画出应变片位置线，完后取下装置，轮轨上留下精准的粘贴位置指示。The buckle mechanism is located directly above the rail head. In actual use, place the device on the rail to be calibrated. After finding the center position between the two fasteners through the centering hole, draw a positioning frame along the outline of the calibration hole, and draw a line along the groove. Draw the position line of the strain gauge, and then remove the device, and leave a precise sticking position indicator on the wheel rail.
