Abstract

The invention discloses a method and device for measuring the size of an automobile aluminum hub finished product on line and relates to the field of automation measurement and control. The device for measuring the size of the automobile aluminum hub finished product on line comprises a detecting station, a pneumatic clamping device, two laser sensors, a PLC module which controls measuring motions and data processing software which is used for saving data and processing an industrial personal computer. The diameter and the depth of a finished cap buckling groove and the diameter of a cap rabbet can be measured simultaneously by means of centering of the hub and matching of primary scanning of a double laser. The device for measuring the size of the automobile aluminum hub finished product on line has the advantages of achieving full-automatic online measurement, being high in precision and rapid in measurement, causing no damage to the surface of the hub, being applicable to measurement of hubs with various sizes, and improving production efficiency of an enterprise. According to the method and the device for measuring the size of the automobile aluminum hub finished product on line, a measuring process can be automatically carried out, measurement is adapt to serious environment and can not be influenced by vibration, smog and humidity, the overall measuring time lasts for 10s, the measuring process is simple and fast, the measuring precision can reach 10 microns, and actual measuring requirements can be met.

Description

technical field [0001] The invention relates to the field of automatic measurement and control, in particular to an on-line size measurement system for finished automobile aluminum alloy wheel hubs. Background technique [0002] With the development of modern society, the automobile industry has gradually become one of the pillar industries in China. As one of the important components of automobiles, aluminum alloy wheels are widely used because of their advantages such as light weight, small deformation, environmental protection and energy saving. [0003] With the rapid development of the automobile market, the demand for fast and correct detection of the finished wheel hub size is becoming more and more urgent. Figure 1a , shown in 1b) as the installation position of the car decoration cover, its size is the key assembly size and an important indicator affecting the quality of the wheel hub. If the size of the buckle cap groove and the cap stop is out of tolerance, the ...
