Problems solved by technology

In terms of wheel hub blank measurement, the application of laser on-line measurement has just emerged. Due to the extremely irregular shape of the blank, there are relatively few reports on its deformation measurement.
The Austrian MNI company has developed the MEAS DIS Serie300 series laser on-line measurement device, which measures the deformation of the wheel hub blank at different positions by selecting 6-8 points, but this system has few measurement positions and measurement points, and cannot accurately measure the deformation of the rim surface

Abstract

The invention discloses an on-line automobile aluminium alloy hub blank deformation measurement method and a measurement device which relate to the field of automated measurement. The measurement device comprises a test table, a pneumatic clamping mechanism, an air cylinder lifting mechanism, a hub-rotating mechanism, two laser sensors, a motion control module, an industrial personal computer for storing and processing data, and data processing software. By scanning a hub blank in all directions, the measurement device can simultaneously measure the wheel rim deformation and the center axial deformation of the hub blank, thus achieving the effects of high measurement accuracy, more measurement points, high speed and high reliability, automatically measuring the hub blank on line, and increasing the production efficiency of enterprises. The process of measurement is automatic, measurement can be adapted to harsh environments, and cannot be affected by vibration, smoke or humidity, the total measurement time is 30 seconds, the measurement precision is 0.02mm, and the actual demand on measurement can be satisfied.

Description

technical field [0001] The invention relates to the field of automatic measurement and control, in particular to an on-line deformation measurement system of an automobile aluminum alloy wheel hub blank, which realizes on-line measurement of the deformation of the rim surface of the wheel hub blank and the axial deformation of the center of the wheel hub. 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] In the production process of aluminum alloy wheels, due to the influence of factors such as the size of the abrasive tool, casting method, thermal deformation of the blank, heat treatment, etc., the actual shape of the wheel hub blank will have a certain deviation f...
