[0026] The working principle of the indicating guide rail straightness detector provided by the utility model is as follows: Figure 5 To measure the straightness of the guide rail 16, first install the left bracket 14 and the right bracket 19 at both ends of the guide rail 16, and tighten the left bracket 14 and the right bracket 19 with the fixing screws. Then hang the thin steel wire 18 on the left bracket 14 and the right bracket 19, and hang the left weight 15 and the right weight 17 at both ends of the thin steel wire to straighten the thin steel wire 18; finally, place the indicating guide rail straightness tester on the guide rail 16, rotate the differential cylinder 10 of the inner diameter micrometer 9, so that the measuring head of the differential cylinder 10 just touches the thin steel wire 18 to stop measuring, and at this time, observe the scale value on the fixed sleeve and the differential cylinder 10, which is the height value of the guide rail relative to the thin steel wire 18 at this point. Use the same method to move the guide rail straightness tester to measure the value again, and then measure the height value of each point of the guide rail by analogy, and finally connect the values ​​of all the measured points to detect the guide rail straightness curve.

[0027] The electrical principle of the utility model for measuring the straightness of the guide rail is to refer to Figure 1-5First, place the indicating guide rail measuring instrument on the guide rail 16, rotate the differential cylinder 10 of the inside micrometer 9 so that the measuring head of the differential cylinder 10 approaches and touches the thin steel wire 18. At this time, since the thin steel wire connects the circuit, the indicator light 11 lights up, and the rotation of the differential cylinder 10 is stopped. At this time, the scale values ​​observed on the fixed sleeve and the differential cylinder 10 are the height values ​​of the guide rail relative to the thin steel wire 18 at this point.

At this time, the scale values ​​on the fixed sleeve and the differential cylinder 10 are the height values ​​of the guide rail relative to the thin steel wire 18 at this point. Use this method to measure successively and thus the guide rail straightness curve can be measured.

[0030] Reference Figure 1-4 When measuring, rotate the differential cylinder 10 of the inside micrometer 9 so that the measuring head of the differential cylinder 10 approaches and touches the thin steel wire 18.
