Abstract: The traditional domestic automotive wheel hub production lines have many problems, such as low levels of intelligence, the need for a large number of workers to assist in multiple production links, and low production quality and efficiency. This article conducts an in-depth analysis of the traditional production process of automotive wheel hubs, applies the digital twin technology of industrial robots to the production of automotive wheel hubs, builds a digital twin model of the actual production line through the virtual debugging software PQFactory, and successively completes the definitions of each sensor and state machine variable. Through the commissioning and operation verification of the digital twin automotive wheel hub production line, the intelligent control and operation of the production line have been achieved, improving the quality and efficiency of automotive wheel hub production.
