Problems solved by technology

However, the length of the extension rod of the existing height measuring instrument is fixed, and the direction of its extension is also fixed, so that it is impossible to conveniently measure the heights of multiple surface positions with different height differences on the same element to be measured. Measurement efficiency is greatly limited

Embodiment Construction

[0015] The height measuring instrument of the technical solution will be described in further detail below in conjunction with the accompanying drawings.

[0016] see figure 1 , The height measuring instrument 100 provided by the embodiment of the technical solution includes a base 10 , a guide rod 20 , an extension rod 30 and a height gauge 40 .

[0017] The base 10 has a first surface 12 and a second surface 14 . The first surface 12 is parallel to the second surface 14 . The first surface 12 is a plane, which is used to carry the element to be measured.

[0018] The guiding rod 20 is fixed on the base 10 and is perpendicular to the base 10 , that is, perpendicular to the first surface 12 . The guide rod 20 is approximately a cylinder.

[0019] The extension rod 30 includes a sliding part 31 , a first extension part 32 , a second extension part 33 , a fixing screw 34 , a connection part 35 and a horizontal bubble gauge 36 . The end of the first extension 32 and the seco...

Abstract

The invention provides a height measuring instrument which comprises a base, a guide rod, an extension rod and a height gage, wherein the guide rod is fixed on the base; the extension rod comprises a slide part which can be slidably sleeved on the guide rod and used for the axially moving along the guide rod; the height gage is arranged at one end of the extension rod away from the guide rod; theextension rod is provided with a first extension part and a second extension part parallel to the first extension part; one ends of the first extension part and the second extension part, which are away from the guide rod, are respectively provided with a connecting part used for connecting the first extension part and the second extension part; and the second extension part can slide and rotate relative to the connecting part. The invention also provides a height measuring method utilizing the height measuring instrument to measure.

Description

technical field [0001] The invention relates to measurement technology, in particular to a height measuring instrument. Background technique [0002] As an important aspect of measurement technology, height measurement requires a height measuring instrument suitable for various measurement situations. For example, in the paper A Novel Optical Method of Dimension Measurement of Objects with Circular Cross-section published by Tomas Fischer et al. method. [0003] At present, a height measuring instrument is mainly composed of a base, a guide rod, an extension rod and a height gauge. The base is mainly used for fixing and supporting components such as guide rods. When measuring, first place the element to be measured on the base, then adjust the height of the extension rod along the axial direction of the guide rod, so that the height gauge sleeved in the extension rod moves with the extension rod, and then fine-tune the height gauge to make the measurement of the height ga...
