Automatic scanning detection device and method for large-scale engineering mechanical structures

Abstract

The invention provides an automatic scanning detection device for large-scale engineering mechanical structures, and relates to the field of engineering mechanical structure detection. The device comprises a three-axis feeding mechanism, a scanner clamping mechanism, a swing mechanism and a sliding table mechanism, wherein the sliding table mechanism comprises a base and a sliding plate. Accordingto the device, a scanner can move according to control tracks described by a numerical-control program, so that the useless tracks are decreased; the scanning process is stable and free of shake, sothat the scanning efficiency is improved and the labor intensity is reduced; the feeding motion of each axis does not need linkage; compared with the existing scanning robots, the device is simple instructure, convenient to operate and relatively low in cost; the special swing mechanism and a positioning mechanism are arranged, so that the device can be adapted to different types of large-scale engineering structures with different sizes; and meanwhile, the scanner clamping mechanism can complete pitching and rotary motions, and adopts flexible clamping, so that the device is suitable for most of the 3D scanners on the market.

Description

technical field [0001] The invention relates to the field of detection of construction machinery structural parts, in particular to an automatic scanning detection device and method for large construction machinery structural parts. Background technique [0002] A 3D scanner is a scientific instrument used to detect and analyze shape and appearance data of objects or environments in the real world. The collected data is often used to perform 3D reconstruction calculations, creating digital models of actual objects in the virtual world. These models have a wide range of uses, such as industrial design, defect detection, reverse engineering, robot guidance, landform measurement, medical information, biological information, criminal identification, digital cultural relic collection, film production, game creation materials, etc. application. The production of 3D scanners does not rely on a single technology. Various reconstruction technologies have their advantages and disadv...

AI Technical Summary

Problems solved by technology

At present, the 3D scanners on the market for scanning large-scale construction machinery structural parts are mainly hand-held scanners, which are light and flexible. However, for large-scale engineering structural parts, the scanning time is long and labor-intensive. Shaking will affect the scanning quality, and the operator needs to pay attention to the scanning results on the display screen when scanning, which is less efficient

Existing inspection robots are expensive and are not suitable for scanning and inspection of single-piece and small-batch products in small and medium-sized enterprises
