Embodiment Construction

[0005] Specific implementation

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

[0007] Its working principle is: the main ruler is engraved with a scale in millimeters as the unit and marked with numbers, and the sub ruler is evenly engraved with 100 lines, the width between each line is 0.99 mm, and the total length of the scale on the sub ruler It is 99 mm and marked with numbers. When the micrometer caliper is closed, the first line on the m...

Description

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