Description

Technical Field

[0001] This utility model belongs to the field of manufacturing, and specifically relates to a height difference measuring ruler. Background Technology

[0002] In the manufacturing process of composite material parts, vertical height is often used to determine whether the relative positions of components such as honeycomb, ribs, and beams meet the theoretical numerical requirements of drawings and digital models. Since the components themselves have a certain height, there are situations where it is necessary to ensure that both the upper and lower boundaries of the components meet the theoretical vertical height. The accuracy of the measured position is related to important properties of the parts, such as bonding quality, strength, and electrical properties.

[0003] Currently, in the manufacturing process of composite material parts, the vertical height of components is usually determined by first measuring with a height gauge to determine the lower boundary, then adjusting the gauge's tip to determine the upper boundary, or by using two height gauges together and subtracting the upper and lower boundaries to obtain the component's vertical height. This measurement method is cumbersome, time-consuming, and labor-intensive, and cannot provide a direct and quick reading of the upper and lower boundaries and the height difference between them. Furthermore, there is an accumulation of errors from the two measurements. Utility Model Content

The first vertical ruler is vertically mounted on the base. The first horizontal ruler is vertically fitted onto the first vertical ruler and can move up and down. The first horizontal ruler has a first downward protrusion at its end that overlaps the lower measuring surface. The second vertical ruler is vertically fitted onto the first horizontal ruler and can move horizontally. The zero-position scale line of the second vertical ruler is aligned with the upper edge of the profile of the first horizontal ruler. The second horizontal ruler is vertically fitted onto the second vertical ruler and can move up and down. The second horizontal ruler has a second downward protrusion at one end that overlaps the upper measuring surface, and a pointer at the other end. The pointer is coplanar with the lower edge of the profile of the second horizontal ruler. The base, the first downward protrusion, and the second downward protrusion are all the same height.

[0006] Advantageously, the zero mark of the first vertical ruler is aligned with the upper surface of the base.

[0018] See Figure 1 The height difference measuring ruler shown in the embodiment includes: a base 2, a first vertical ruler 3, a first horizontal ruler 4, a second vertical ruler 5, a second horizontal ruler 6, a ruler head 7, and several fastening screws (including a first fastening screw 8, a second fastening screw 9, and a third fastening screw 10).

[0019] The first vertical ruler 3 is vertically installed on the base 2, and the thickness of the base 2 is a. The first vertical ruler 3 is provided with a first scale for reading the height h1 of the lower measuring surface relative to the reference surface and the height h2 of the upper measuring surface relative to the reference surface.

[0020] The first horizontal ruler 4 has a vertical through hole at one end. The first horizontal ruler 4 is fitted onto the first vertical ruler 3 through the through hole, allowing it to move up and down along the first vertical ruler 3 and be positioned by the first fastening screw 8. The first horizontal ruler 4 is perpendicular to the first vertical ruler 3. At the other end, the first horizontal ruler 4 has a first downward protrusion that overlaps the lower measuring surface. The height of the first downward protrusion is 'a'. The lower edge of the first horizontal ruler 4 is indicated on the scale of the first vertical ruler 3 as the height h1 of the lower measuring surface relative to the reference surface.

[0021] The second vertical ruler 5 has a second horizontal through hole at its lower end. The second vertical ruler 5 is fitted onto the first horizontal ruler 4 through the second through hole, allowing it to move laterally along the first horizontal ruler 4 and be positioned by the third fastening screw 10. The second vertical ruler 5 is perpendicular to the first horizontal ruler 4. The second vertical ruler 5 is equipped with a second scale, the 0 mark of which is flush with the upper edge of the profile of the first horizontal ruler 4, for directly reading the height difference Δh between the lower and upper measuring surfaces.

[0022] The second horizontal ruler 6 has a vertical third through hole at one end. The second horizontal ruler 6 is fitted onto the second vertical ruler 5 through the third through hole, allowing it to move up and down along the second vertical ruler 5 and be positioned by the second fastening screw 9. The second horizontal ruler 6 is perpendicular to the second vertical ruler 5. The second horizontal ruler 6 also has a scale head 7 on its outer end face. The scale head 7 is coplanar with the lower edge of the profile of the second horizontal ruler 6 and points towards the scale of the first vertical ruler 3. The second horizontal ruler 6 has a second downward protrusion at its other end, which overlaps the upper measuring surface. The height of the second downward protrusion is 'a'. The indication scale of the scale head 7 on the first vertical ruler 3 is the height h2 of the upper measuring surface relative to the reference surface.

[0023] In another embodiment, the head 7 is a sleeve-type telescopic structure. When the distance between the second vertical ruler 5 and the first vertical ruler 3 changes, the length of the sleeve can be adjusted to read the height h2 of the upper measuring surface relative to the reference surface.

[0024] In another embodiment, the first downward protrusion of the first horizontal ruler 4 and the second downward protrusion of the second horizontal ruler 6 are hemispherical.

[0026] The first vertical ruler 3 and the second vertical ruler 5 are provided with limiting structures at their ends. The limiting structure of the first vertical ruler 3 is used to prevent the first horizontal ruler 4 from slipping off, and the limiting structure of the second vertical ruler 5 is used to prevent the second horizontal ruler 6 from slipping off.

[0027] The measuring ranges of the first vertical ruler 3, the second vertical ruler 5, the first horizontal ruler 4, and the second horizontal ruler 6 can be customized according to measurement needs.

[0028] During measurement, adjust the first downward protrusion of the first horizontal ruler 4 to overlap the lower measuring surface and tighten the first fastening screw 8; next, adjust the lateral position of the second vertical ruler 5 on the first horizontal ruler 4 so that the second downward protrusion of the second horizontal ruler 6 can overlap the upper measuring surface and tighten the third fastening screw 10; then, adjust the second downward protrusion of the second horizontal ruler 6 to overlap the upper measuring surface and tighten the second fastening screw 9; then, pull out the sleeve of the pointer 7 so that it points to the first scale of the first vertical ruler 3; by reading the scale through the line of sight, the lower edge of the profile of the first horizontal ruler 4 on the scale of the first vertical ruler 3 is the height h1 of the lower measuring surface relative to the reference surface, the pointer 7 on the scale of the first vertical ruler 3 is the height h2 of the upper measuring surface relative to the reference surface, and the upper edge of the profile of the second horizontal ruler 6 on the scale of the second vertical ruler 5 is the height difference Δh between the upper and lower measuring surfaces.
