[0019] The technical solution of the utility model is further explained below with reference to the accompanying drawings and through specific implementation methods.

[0020] A micrometer for measuring the outer diameter of a large rolling mill roll comprises a ruler body 1, a knob measuring end 2 and a fixed measuring end are mounted on the end of the ruler body 1, the knob measuring end 2 is used to measure the outer diameter of the rolling mill roll, and a symmetrical mounting column 3 is fixedly connected to the ruler body 1, and an auxiliary support plate 4 is arranged on the mounting column 3, and the auxiliary support plate 4 is used to consolidate the position of the ruler body 1 on the rolling mill roll.

[0021] like Figure 1-3 As shown, the ruler body 1 is set to be semi-circular in shape, and the knob measuring end 2 and the fixed measuring end are respectively arranged at both ends of the ruler body 1, wherein the knob measuring end 2 and the fixed measuring end have the same working principle as those on the traditional micrometer, and the specific process is not repeated in detail here, and the symmetrical mounting posts 3 are respectively fixed on the side of the ruler body 1, and the auxiliary support plate 4 is installed on the end of the mounting post 3;

[0022] When measuring, place the ruler body 1 on the roller so that the end of the auxiliary support plate 4 contacts the roller surface, so that the auxiliary support plate 4 supports the side of the ruler body 1 through the mounting column 3, and forms a three-contact stability frame with the fixed measuring end, so that the operator does not need to hold the micrometer by hand. After the operator determines the measuring position, the outer diameter of the roller is measured by turning the knob measuring end 2;

[0023] Compared with the existing micrometer, the utility model enables the micrometer to be stably placed on the roller surface, and through the three-contact frame structure, a single person can perform the measurement operation, reducing the time required for micrometer measurement, which is conducive to improving the efficiency of micrometer measurement and the accuracy of measurement.

[0024] As a possible implementation mode of the present scheme, preferably, the mounting column 3 is rotatably connected to the auxiliary support plate 4; this is beneficial for the auxiliary support plate 4 to be able to support rollers of different sizes, thereby improving the applicability range of the micrometer and improving the practicality of the micrometer.

[0025] As a possible implementation manner of the present scheme, preferably, a torsion spring is provided at the rotating portion of the mounting column 3; when the ruler body 1 is mounted on the rolling roller, the auxiliary support plate 4 rotates clockwise, wherein the reaction force of the torsion spring on the auxiliary support plate 4 causes the end of the auxiliary support plate 4 to maintain contact with the roller surface, thereby allowing the micrometer to be placed on the rolling roller in a perpendicular state to the horizontal axis of the rolling roller, which is beneficial to improving the accuracy of the micrometer measurement and maintaining a distance between the ruler body 1 and the roller surface, which is beneficial to the normal measurement work of the knob measuring end 2.

[0026] As a possible implementation of this solution, preferably, Figure 1-2 As shown, the end of the auxiliary support plate 4 is rotatably connected with a universal ball 5; the universal ball 5 is embedded in the bottom surface of the front end of the auxiliary support plate 4, so as to reduce the friction between the auxiliary support plate 4 and the roller surface, making it easier for the micrometer to move on the roller, thereby helping the operator to find the accurate measuring point faster and further improving the measurement efficiency of the micrometer.

[0027] As a possible implementation of this solution, preferably, Figure 3 As shown, a bending portion 6 is provided on the auxiliary support plate 4; the surface of the bending portion 6 is flush with the tangent of the roller, and the universal wheel is installed at the head end of the auxiliary support plate 4. The bending portion 6 makes the head end of the auxiliary support plate 4 perpendicular to the roller surface, so that the lowest point of the universal wheel maintains a contact state with the roller surface, which is beneficial to improve the supporting effect of the auxiliary support plate 4 on the side of the ruler body 1, thereby helping to improve the stability of the micrometer on the roller, thereby helping to improve the accuracy of micrometer measurement.

[0028] As a possible implementation of this solution, preferably, Figure 1As shown, a plurality of circular holes 7 are formed on the ruler body 1; the circular holes 7 are evenly distributed on the ruler body 1, and an operator can hold the ruler body 1 through the circular holes 7, so as to facilitate the ruler body 1 to move on the roller and find an accurate measurement position, which is also beneficial to reducing the processing materials and cost of the ruler body 1.

[0029] The present invention is described by preferred embodiments, and those skilled in the art will appreciate that various changes or equivalent substitutions may be made to these features and embodiments without departing from the spirit and scope of the present invention. The present invention is not limited to the specific embodiments disclosed herein, and other embodiments falling within the claims of this application are within the scope of protection of the present invention.
