On April 10th, with the first batch of 50 heavy-duty engines smoothly off the assembly line, it was announced that the current domestic heavy-duty diesel engine test line with world advanced level was officially completed and put into production in Yuchai.
This heavy-duty diesel engine test line with an investment of 220 million yuan covers an area of ​​more than 16,000 square meters. It costs only 140 million yuan to import equipment. The major equipments are imported from Europe. The production line adopts on-line measurement, on-line collection, dynamic information management system, PMS (production management system), QDM (quality management), and PMS system to realize the whole process monitoring from production to production.
The test line innovatively uses a number of advanced process designs and has introduced four advanced assembly lines from Germany. It adopts the currently popular internal and external assembly lines and is equipped with advanced on-line inspection, semi-automatic assembly equipment, quality and production management systems, and advanced semi-finished products. Spray painting process, ABB robot automatic painting, not only to improve the working environment of the operator, but also to improve the appearance of the product quality; AGV trolleys for the first time to transport, improve safety and save equipment space, but also greatly improve the transport efficiency. The pre-assembly line of the test machine is responsible for the installation and inspection of the relevant tooling and auxiliary parts before the test machine, to achieve centralized management, reduce the auxiliary time on the bench, and increase the utilization rate of the bench up to 30%.
In addition, in every post of the assembly, the system automatically presents the station information, such as the online detection of the protruding height of the cylinder sleeve, the accurate positioning and measurement of the crankshaft, the automatic reversal, the automatic camshaft, the automatic tightening, and the on-line measurement integration. The stability of parts and quality is controlled. The automatic and semi-automatic degree of the entire production line has reached more than 50%, which will greatly reduce the labor intensity of workers and increase the production efficiency. It is currently the most advanced heavy-duty diesel engine test production line in China. Its successful production has accelerated Yuchai's determination to lead the development of heavy machinery and is a new growth point for Yuchai to accelerate its development.
