A well-known concrete mixing equipment company in order to test the concentricity (ie, the degree of deformation) of the horizontal shaft hole of the concrete mixer after the work, to improve the quality of the product and increase the company's competitiveness

Practical problems

1. The concrete mixer is huge (4 meters * 3 meters * 2.8 meters) and complex in shape, which requires very high requirements for the three-dimensional scanner

2. The scanning shaft hole needs to be scanned inside the concrete mixer. The internal space is narrow and the machine does not rotate well.

3. The bad weather in Xinjiang, the temperature is as low as 20 degrees below zero, which also causes difficulties for the operation of the machine

Concrete mixer appearance

1. Preliminary preparations

Spray developer: improve the contrast of the background color on the surface of the sample and obtain better scan data.

Paste the mark point: make the acquired data be positioned and spliced in the scanning software.

2. Three-dimensional scanning

A well-known concrete mixing equipment company is to test the concentricity (deformation) of the horizontal shaft hole of the concrete mixer after working. The traditional solution is repeated debugging by manual measurement and rough calculation, that is, there is no efficiency and no precision, which can not meet the requirements of the market at all, so new solutions have to be sought. Hualang 3D technical engineers use Hualang 3D scanner HL-3DS+ to scan it. The machine is very suitable for scanning large objects. The machine is very stable. The entire scanning process takes only one hour and the accuracy reaches 0.05mm, which is far beyond customer expectations. Accuracy not only saves time and manpower, but the most important thing is to help customers earn a place in the market.

3D data of horizontal axis hole of concrete mixer

3. Three-dimensional inspection

Import the acquired three-dimensional data of the horizontal shaft hole of the concrete mixer into the inspection software Geomagic Qualify, which can quickly detect the difference between the horizontal shaft hole (CAD) model of the concrete mixer and the manufactured parts of the product. Geomagic Qualify can use intuitive and easy-to-understand graphics Comparing the results to show the difference between the two, it is possible to carry out detailed analysis of the characteristics of the horizontal axis of the concrete mixer, and at the same time to capture and reflect the shape and position deviation of the section.
