The multi-station and multi-parameter vision measuring system comprises a Y-shaped feeding mechanism, a multi-station chain type feeding mechanism, a radial parameter measuring device, an axial parameter measuring device, a warehousing type three-dimensional sorting mechanism, a PLC (Programmable Logic Controller) control module, a human-machine interaction interface and an upper computer control system. The invention can provide geometrical quantity precision measuring equipment for the quality control of processing of the rotary parts on industrial field. The geometrical quantity precision measuring equipment can be used for detecting the geometric dimension error, shape error and position error and counting and analyzing the detection result of the same batch of parts to grasp the fluctuation condition of the batch quality of products. Meanwhile, the equipment has functions of automatically feeding parts and automatically sorting according to the measuring result and can be directly connected in series to the production line in series for on-line and full-detection of the parts.

Description

technical field [0001] The invention relates to the field of measurement and testing, in particular to a visual measurement and automatic sorting system for geometric dimensions, shapes and position errors of rotary parts. Background technique [0002] The measurement of the geometric size, shape and position error of mechanical parts is an important link to ensure the accuracy and quality of products. Due to the diversity and complexity of mechanical parts, the measurement methods for the geometric quantities of different parts are also different. Usually, the geometric quantity measurement method mainly uses workers to measure parts by using mechanical, electronic, pneumatic and optical measurement tools, but most of them have shortcomings such as being affected by human factors, low degree of automation, and low measurement efficiency. , it is difficult to meet the quality control requirements of large batches of parts. [0003] With the standardization and legalization...
