Problems solved by technology

[0003] In addition, the vernier scale of the traditional vernier caliper is very large and the width is large, especially the vernier scale with 50 divisions, which limits the moving range of the vernier caliper, which also limits the measuring range of the vernier caliper

Embodiment 1

[0025] On the one hand, the embodiment of the present invention provides a vernier caliper, such as figure 1 As shown, it includes a main ruler 1 arranged horizontally. In this embodiment, the main ruler 1 is rectangular in shape, and a vernier ruler 3 is arranged vertically. The vernier ruler 3 is slidably connected to the main ruler 1; A plurality of first scale lines 2 are uniformly distributed, and the length of the first scale lines 2 extends to the bottom of the main scale 1. In this implementation, the length of the first scale lines 2 occupies 10% of the width of the main scale 1. Two-thirds, the distance between the first scale marks 2 is 1mm;

[0026] Described vernier scale 3 is provided with transparent scale plate 4, and described transparent scale plate 4 is located at the area that vernier scale 3 overlaps with main chi; Described scale plate 4 is set to be transparent and reads measured value for convenient observation, and described The inner surface of the t...

Embodiment 2

[0030] On the other hand, the embodiment of the present invention also provides a kind of vernier caliper measurement method, and described method comprises the following steps:

[0031] Attach one end of the part to be measured to the claw of the main ruler 1; the vernier 3 moves laterally along the main ruler, and fit the claw of the vernier 3 to the part to be measured; when the first scale line 2 on the main ruler 1 When coincident with the second scale line 5, read the reading above the millimeter according to the scale of the first scale line 2 that overlaps; read the reading below the millimeter according to the scale of the second scale line 5 that overlaps;

[0032] When the first scale line 2 was between the two second scale lines 5, the reading above the millimeter was read according to the scale of the first scale line 2; the second scale line 5 close to the first scale line 2 was selected, According to its scale, read the reading below millimeter;

Abstract

The invention discloses a vernier caliper and a measuring method, and belongs to the technical field of measurement, the vernier caliper comprises a transversely arranged main scale and a longitudinally arranged vernier scale, and the vernier scale is slidably connected to the main scale; a plurality of first scale marks are uniformly distributed on the main ruler; the vernier scale is provided with a transparent scale plate, the inner surface of the transparent scale plate is attached to the main scale, the transparent scale plate is provided with a plurality of second scale marks which are obliquely distributed along the transparent scale plate, and the second scale marks are uniformly distributed within the scale mark range of the main scale; the vernier scale transversely moves along the main scale, the second scale mark on the vernier scale coincides with the first scale mark on the main scale, and the measurement value on the second scale mark and the measurement value on the first scale mark are added to form a measurement result. The width of the second scale line is set to be 1 mm, and the scale lines which are too close in the transverse direction are separated in the height direction by expanding in the height direction, so that observation is facilitated, and the measurement precision is improved.

Description

technical field [0001] The invention discloses a vernier caliper and a measuring method, belonging to the technical field of measuring. Background technique [0002] In daily or industrial fields, when more precise size measurement is required, conventional measurement tools include vernier calipers, screw micrometers, digital calipers, etc. The vernier caliper is a commonly used instrument for measuring length in industry. It consists of a main ruler and a vernier that can slide on the main ruler. When measuring, first read the scale of the main ruler to obtain a reading of more than millimeters, and then find the Scale aligned with the scale on the main scale for readings down to millimeters. To achieve the reading, you need to read the tick marks in two different places. [0003] In addition, the traditional vernier caliper has many scales and a large width, especially the vernier with 50 divisions, which limits the moving range of the vernier and also limits the measur...
