Problems solved by technology

This measurement method is time-consuming and labor-intensive, and the work efficiency is extremely low. It is often necessary to measure the thickness value of hundreds of points for each steel plate. Moreover, it is still the measurement of each intermittent point rather than the measurement of continuous plate shape, so it is impossible to obtain accurate points. thickness value

Embodiment Construction

[0019] based on the following Figure 1 ~ Figure 2 , illustrating a preferred embodiment of the present invention.

[0020] Such as figure 1 As shown, the measured plate 3 advances along the upper and lower symmetrical measuring wheels 11, 11', and the measuring wheels 11, 11' receive the plate thickness change of the section of the measured plate 3, and make up and down displacements, thus driving the transmission The rod 12 and the transmission rod 12 are vertically inserted in the guide linear bearing 13 to form a mechanical transmission structure. The guide linear bearing 13 is displaced up and down; a measurement reference plate 14 is set above the guide linear bearing 13, and the measurement reference plate The horizontal plane where 14 is located is perpendicular to the upper and lower displacement movement planes of the guide linear bearing 13, and the guide linear bearing 13 drives the measurement reference plate 14 to move up and down, and a high-precision eddy curr...

Abstract

The cross section contour detecting method for steel plate and steel belt includes the following steps: guiding the measured body into the measuring instrument and making the measured body move relatively to the instrument; measuring the varying thickness of the measured body with the instrument and converting the thickness variation into electric signal; and collecting the displacement signal with computer to obtain the cross section contour curve of the measured body. The measurement method is continuous, precise, simple and low in cost.

Description

technical field [0001] The invention relates to a mechanical measurement method, in particular to a high-precision detection method for the cross-sectional profile shape of a strip steel sheet. Background technique [0002] As one of the most important products of the iron and steel industry, strip steel plays a very important role in the development of the national economy. It is widely used in industry, agriculture, national defense and daily life. With the rapid development of modern industry and science and technology, the vast number of users of industrial enterprises have put forward more and more strict requirements on the quality of strip steel. One of the most important quality indicators is the shape of steel. Technicians in steel mills need to detect the shape quality of a large number of incoming materials and finished strips every day. The current detection methods mainly include contact and non-contact detection. The non-contact type usually uses a ray thickn...
