Abstract

The invention discloses a laser measurement device for the thickness of a plate, and relates to a laser measurement device. In order to the solve the problems that as for a conventional laser measurement method, continuous measurement for the thickness of the plate can not be carried out, the technical scheme I is adopted as follows: an upper arm and a lower arm are arranged in parallel; the upper arm is connected with a side arm; the lower arm is connected with a lateral wall of a U-shaped slide rail; the side arm is connected with chutes in a sliding manner; a horizontal gear on the side arm is meshed with a gear wheel; an upper and a lower laser displacement sensors are respectively fixed on the upper and the lower arms; a long-arm clamp is fixed on a support which is fixed on one group of rollers; two groups of rollers roll along a guidance groove of a guidance rail; each group of rollers are limited through two limiting mechanisms; the side wall is fixed on a working table; the guidance rail is fixed on an upper installation base of an upper motion platform; an upper bracket of the upper motion platform is fixed on a lower installation base of a lower motion platform; and the lower motion platform is arranged in the working table. The technical scheme II is different from the technical scheme I, the side wall is fixed on the upper installation base of the upper motion platform. Due to the adoption of the device provided by the invention, continuous measurement for the thickness of the plate can be carried out.

Description

technical field [0001] The invention relates to a laser measuring device, in particular to a laser measuring device for plate thickness. Background technique [0002] In the industrial production process, the thickness uniformity of the plate is a key factor affecting the later forming, and it is one of the important signs to measure whether the plate is qualified or not. Quickly and effectively measure the plate thickness distribution in the plane of the plate before forming, which can provide a basis for the analysis of the later forming effect. In high-precision fields such as aviation, aerospace, and deep-sea exploration, the requirements for plate thickness distribution before forming plate parts are more stringent. [0003] There are two main types of existing thickness measurement methods, one is contact thickness measurement methods, such as micrometer and ultrasonic thickness measurement, the measurement points need to be marked before measurement, and manual measu...
