Problems solved by technology

[0003] Due to the lack of relevant standards, the current marking methods used by major domestic laboratories in seat adjustment and 3D-H dummy placement are relatively extensive, mainly by finding a surface parallel to the centerline of the car body, and then adjusting the marking device to be parallel to it. Mark distances and reference points by sliding T-shaped slide rails; the current marking device is mainly composed of linear slide rails and aluminum brackets, the overall rigidity is not enough, and the chassis is not flexible enough, which makes parallel adjustment very inconvenient

Abstract

The invention provides a rotational two-dimensional laser measuring instrument and a measuring method thereof. The rotational two-dimensional laser measuring instrument and the measuring method are used for distance measurement and marking in seat adjusting and 3D-H dummy placement processes, and therefore test efficiency is improved. The rotational two-dimensional laser measuring instrument is composed of a car head laser device and a car side laser device, wherein the car head laser device comprises a horizontally-arranged Y-axis guide rail, the Y-axis guide rail is provided with a first base capable of sliding, a vertical Z-oriented guide rail is fixed to the first base and provided with a first sliding block, and the first sliding block is provided with a first laser transmitter capable of horizontally rotating; the car side laser device comprises an X-oriented guide rail horizontally arranged and capable of horizontally rotating, a second base capable of sliding is installed on the X-oriented guide rail and provided with a vertical second Z-oriented guide rail, and a second sliding block is installed on the second Z-oriented guide rail and provided with a second laser transmitter.

Description

technical field [0001] The invention belongs to the technical field of automobile testing, and in particular relates to a rotary two-dimensional laser measuring instrument and a measuring method thereof. Background technique [0002] As consumers pay more and more attention to automobile safety, domestic automobile safety standards are gradually improving, which also puts forward higher requirements for the test methods and equipment precision used in various automobile tests. [0003] Due to the lack of relevant standards, the marking methods used by major domestic laboratories in seat adjustment and 3D-H dummy placement are relatively extensive, mainly by finding a surface parallel to the center line of the car body, and then adjusting the marking device to be parallel to it. The distance and reference points are marked by sliding the T-shaped slide rail; the current marking device is mainly composed of a linear slide rail and an aluminum bracket, the overall rigidity is ...
