[0011] In order to make the purpose, technical solution and advantages of the utility model clearer, the utility model is further described in detail below in combination with specific implementation methods and with reference to the accompanying drawings. It should be understood that these descriptions are only exemplary and are not intended to limit the scope of the utility model. In addition, in the following description, the description of well-known structures and technologies is omitted to avoid unnecessary confusion of the concept of the utility model.
[0012] Specific implementation method: Combination Figure 1-2 As shown, a height measuring instrument comprises two identical cylinders 4, wherein the upper part of the cylinder 4 is open and the lower part is closed, a movable ruler 2 is slidably connected inside the cylinder 4, a vertical transparent plane 6 is arranged on one side of the cylinder 4, the transparent plane 6 can be formed on the outside of the transparent cylinder 4 in an integrated manner, or a notch can be arranged on one side of the opaque cylinder 4, and then a transparent plate is sealed and connected at the notch to form the transparent plane 6, a transparent fixing plate 7 is arranged on the outside of the transparent plane 6, the transparent fixing plate 7 is fixedly connected to the transparent plane 6 or the cylinder 4, a static ruler 1 that can move up and down is arranged between the transparent plane 6 and the transparent fixing plate 7, a bolt 8 is threadedly connected on the transparent fixing plate 7, and the bolt 8 can tighten the static ruler 1 on the transparent plane 6, both the movable ruler 2 and the static ruler 1 are provided with uniform scales, and the unit scale on the movable ruler 2 is smaller than the unit scale on the static ruler 1 by a set value, similar to a vernier caliper, and the two ends of the hose 5 are respectively connected to the inside of the two cylinders 4. When in use, a certain amount of water is poured into the cylinder 4, and the hose 5 is filled with water. The overall density of the movable ruler 2 is less than the density of water, so that it can float.
[0013] Specifically, a vertical guide column 3 is provided in the cylinder 4, a guide bar is provided on the guide column 3, a guide hole penetrating the upper and lower surfaces and coaxial with the movable ruler 2 is provided, a guide groove is provided in the guide hole, and the movable ruler 2 is slidably connected to the guide column 3. The movable ruler 2 does not rotate.
[0014] Furthermore, the unit scale length of the static ruler 1 is 1 mm, and the unit scale length of the moving ruler 2 is 0.98 mm. The moving ruler 2 is provided with 50 unit scales, and the number of unit scales on the static ruler 1 is not less than the number of unit scales on the moving ruler 2.
[0015] When in use, first put the two cylinders 4 together, add water, and after the water surface stabilizes, observe the moving ruler 2, loosen the bolts 8, adjust the positions of the two static rulers 1, so that the same size of the two static rulers 1 is aligned with the zero point of the moving ruler 2 (for example, the zero point of the moving ruler 2 is at 30mm of the net ruler), and then tighten the bolts 8 to fix the static ruler 1. Then place the two cylinders 4 on two measured positions respectively (such as the two ends of the lathe guide rail), observe the relative positions of the static ruler 1 and the moving ruler 2 respectively, and record the values in millimeters. The integer part is read based on the position of the zero point of the moving ruler 2 on the static ruler 1, and the decimal part is read on the moving ruler 2 (find the two most aligned grids, and the reading of this grid on the moving ruler is the decimal part). The comparison difference is the height difference between the two measured positions (for example, the two readings are 3.24 and 2.76 respectively, and the height difference is 3.24-2.76=0.48mm). Adjust the height of the measured part and observe the readings so that the two differences are zero. At this time, the height difference between the two positions is less than 0.02mm.
