After more than three months of research and exploration, the first paving machine complete electrical system vibration test platform in China was successfully trial-produced in Shaanxi Machinery. The operation of this equipment will greatly improve the pass rate of the company's leading product paver. .
On September 6th, the chief engineer Si Xiaozhu, the research institute, the quality assurance department and the relevant personnel of the Anhuan Ministry of Construction witnessed the on-site test of the DVT01 electrical vibration test platform in the company's electro-hydraulic workshop. The platform tests the two assembled electrical circuits that are randomly sampled. As a result, a group of alarms in the sample line is detected, and the display data does not match. After the electrical assembly workers checked, they found that there was a virtual connection, and they immediately repaired them. The process is simple and clear, fast and efficient, and effectively avoids the problem that the electrical system flows down to the process to ensure product stability.
The test bench mainly consists of a bracket, a table top, a vibration mechanism and a shock absorbing mechanism. It completely simulates the actual vibration situation. Under the driving of the vibration mechanism, the three vertical axes of the horizontal, vertical and upper and lower directions are sequentially vibrated, and the random vibration is selected. It is the easiest to expose the axis of the sample defect and verify that the electrical products processed in the workshop meet the technical requirements.
The test platform was designed and developed by Wang Dong, a young engineer of the company's Electro-hydraulic Research Institute. The equipment was designed for the first time in China. The research team of the institute relied on the design experience of the paver for many years, carefully conceived, carefully designed and carefully selected various accessories. With the full cooperation of the electro-hydraulic workshop, it took more than 100 days before and after. Time, and finally successfully produced this test platform. This is also a masterpiece of the company's product process and quality improvement.
