Problems solved by technology

[0002] At present, vernier calipers are used in domestic and foreign industries to measure the size of parts or objects, but the highest accuracy of vernier calipers is 0.02 mm. Although the accuracy of micrometers is 0.01 mm, it is necessary to achieve this accuracy in practical applications. , requires the operator to have a certain degree of proficiency, and it is not very convenient to use, and it can only measure the outer diameter

Embodiment Construction

[0005] specific implementation

[0006] The structure of the high-precision vernier caliper is shown in the figure. It consists of the main ruler 7, the auxiliary ruler 11, the magnifying lens 10, the outer diameter measuring end wall of the main ruler 8, the outer diameter measuring end wall 9 of the auxiliary ruler, the main ruler scale 6, and the auxiliary ruler scale 12. Main ruler inner diameter measuring end wall 1, auxiliary ruler inner diameter measuring end wall 2, auxiliary ruler anti-displacement fixing screw 3, auxiliary ruler fixing screw 4, chute 5, auxiliary ruler pushing pulley 13, magnifying lens fixing screw 14 .

[0007] Its working principle is: the main ruler is engraved with a scale in millimeters and marked with numbers, and the auxiliary ruler is evenly engraved with 100 lines. The width between each line is 0.99 mm. The total length of the scale on the auxiliary ruler 99 mm and marked with numbers. When the high-precision vernier caliper is closed, t...

The high-precision vernier caliper comprises a main scale 7, an adding tape 11, a magnifying glass lens 10, a main scale outer diameter measuring end wall 8, an adding tape outer diameter measuring end wall 9, a main scale graduation 6, an adding tape graduation 12, a main scale inner diameter measuring end wall 1, an adding tape inner diameter measuring end wall 2, an adding tape anti-displacement fastening screw 3, an adding tape retaining screw 4, a chute 5, an adding tape propelling sheave 13 and a magnifying glass lens retaining screw 14. The invention has the advantages that the accuracy is very accurate; the use is convenient and durable; the popularization and the application are easy; and the market prospect is wide.

Description

technical field [0001] The invention relates to a vernier caliper for measuring length and inner and outer diameters. Background technique [0002] At present, vernier calipers are used in domestic and foreign industries to measure the size of parts or objects, but the highest accuracy of vernier calipers is 0.02 mm. Although the accuracy of micrometers is 0.01 mm, it is necessary to achieve this accuracy in practical applications. , requires the operator to have a certain degree of proficiency, and it is not very convenient to use, and it can only measure the outer diameter. The precision of the high-precision vernier caliper is 0.01 mm, and it is easy to use and durable. The accuracy of the vernier caliper is 0.01 mm, which has not been seen at home and abroad, so the market prospect is broad. Contents of the invention [0003] The object of the present invention is to provide a high-precision vernier caliper with an accuracy of 0.01 mm, which is convenient and durable ...
