A well-known Volkswagen parts supplier needs to perform three-dimensional inspection of Volkswagen molds to obtain high-precision three-dimensional data, and build three-dimensional digital model files (CAD drawings) of automobile molds from three-dimensional data to provide structural design, modification design and subsequent quality inspection of automobile molds data support.
Practical problems
1. The volume of Volkswagen's mold is large and the surface shows dark black reflective surface, which increases the difficulty of scanning. The products produced are prone to deformation, so the quality control of automobile molds is particularly important, and there are very high precision requirements for the three-dimensional data of automobile molds.
2. Simply using traditional inspection methods (such as inspection tools, jigs, three-coordinates, etc.) is difficult and takes a long time. The process is cumbersome and time-consuming, and it is not easy to accurately and quickly measure and inspect the structure of automobile molds.
Holon solutions
Because the Volkswagen mold is about 3 meters long, it is large and heavy, and the mold surface presents a dark black reflective surface, which is not easy to scan, and the local contour requires high precision. Our colleagues use traditional detection methods to measure, not only need to spray imaging agent, but also the scanning speed is slow, the work flow is complicated, it takes a long time to complete the scan and it takes about 2 hours to complete the scan, and many size and shape features cannot be effectively measured. , It is easy to produce secondary errors and affect the production efficiency of the product.
In response to the problems faced by customers, Hualang 3D technical engineers used our newly developed photographic 3D scanner W3000 to quickly and accurately obtain 3D data of automobile molds, and it is convenient and quick to scan without spraying developer. The entire scanning process is less than 30%. Minutes, the scanning accuracy is extremely high. Successfully solved the problems faced by customers.
Scanning device:
Hualang newly developed 3D scanner HL-W3000
Applicable fields:
Automobiles and parts, molds, large castings, aircraft parts, boats, large blades, construction machinery, etc.
Features:
● Convenient operation: no need to spray developer, easy to scan
● Portable design: The hardware system is small in size, occupies a small area, no noise, easy to disassemble and assemble, convenient to bring to the measurement site
● The scanning speed is extremely fast: millions of data points can be obtained within ≤3-5 seconds, and the efficiency is extremely high
● High precision: single scan accuracy can reach 0.02mm, compatible with photogrammetry system, photography makes the scanning speed faster and higher precision, ±0.04mm/4m
● Patented design: Eliminates the problem that common 3D scanners cannot be spliced in multi-angle scanning. The cumulative scanning accuracy is extremely high. A single machine can scan workpieces of more than 4m. The data has no steps, deformations, stripes, etc., and it is suitable for a variety of workpiece requirements.
