[0020] A dial indicator arm sealing plate structure 13 is provided on the inner side of one of the circular through hole structures 9, and a dial indicator mounting arm structure 14 is installed on the inner side of the dial indicator arm sealing plate structure 13. The dial indicator mounting arm structure 14 is connected to the mounting plate 21 on the dial indicator 15. The dial indicator mounting arm structure 14 includes a mounting arm fixing plate structure 16 and a dial indicator connecting plate 17. The upper part of the mounting arm fixing plate structure 16 passes through the upper end cover 7, and the lower part passes through the lower end cover 8. An open groove structure 18 is provided on both the upper end cover 7 and the lower end cover 8. The dial indicator connecting plate 17 includes a left connecting plate 19 and a right connecting plate 20. The mounting plate 21 is arranged between the left connecting plate 19 and the right connecting plate 20, and is connected by bolts.

[0021] The dial indicator 15 is installed on the bottom surface of the angle gauge seat body structure 6 through a bottom baffle structure 28, and an angle gauge spring plate structure 22 is installed and connected to the bottom of the angle gauge seat 5 through an elastic structure, and the elastic structure includes an angle gauge spring guide column structure 23, and a flat gasket structure 24 is arranged above the angle gauge spring guide column structure 23, and an angle gauge spring structure 26 is arranged between the flat gasket structure 24 and the upper end surface of the angle gauge seat base 25, and the angle gauge spring plate structure 22 and the angle gauge seat 5 are both provided with a through hole structure 27 that allows the dial indicator head 29 to pass through.

[0022] Simulate the torque generated by the actual specimen during the test:

[0023] Test requirements:

[0024] In the test mold, the actual sample height is simulated to produce an internal deflection angle. We designed it as follows: the internal rotation angle measuring device is made of hard cylindrical material with the same diameter as the sample. It does not deform under pressure. There are protruding cylindrical tables on the top and bottom (as shown in the figure above). The table height is the standard sample height and the table diameter is 44mm, which meets the 22mm center eccentricity requirement. Because it does not deform under normal load. When the test mold barrel is tilted, the upper and lower pressure plates receive the applied load, and the internal rotation angle measuring device simulates the change in the inclination of the sample in the test mold barrel. The angle between the pressure plate and the table is the test mold inclination angle.

[0025] Angle measurement method:

[0026] The angle between the pressure plate and the table is the inclination angle of the test mold. The test principle of the internal rotation angle measuring device: as shown in the figure, in the test device, the dial indicator is fixed together with the test frame, the test frame can slide up and down, and the measuring point A is in contact with the pressure plate. When the test mold rotates, the test point B will produce an up and down position change. The distance between the test point A and the test point B is fixed, and it can be calculated based on the displacement of point B.

[0027] The beneficial effects of the present invention are:

[0028] The dynamic internal rotation angle measuring device of the present invention can make the SGC pressure plate generate a tilting torque when rotating in the SGC test mold, and simultaneously measure the internal rotation angle and rotation speed, thereby calibrating the internal deflection angle of the rotary compactor. Such a design has strong practicality and broad market application prospects.
