1 Large-scale bolt fastening robot system for flexible assembly of wind turbine
In the wind turbine manufacturing process, manual hydraulic wrench operation was originally used. 6 workers in each production base can only produce 2 wind turbine products every day; after a leading enterprise in the wind power industry used a large-scale bolt tightening robot system manufactured by Aerospace Intelligence , It can realize the output of 6 sets by one person, which greatly improves the production efficiency and reduces the product failure rate; realizes the storage of production and processing product data, which is of great help to the later product upgrade and optimization.
2 Large-scale bolt tightening and tensioning robot system for wind turbines
In the manufacturing process of offshore wind turbines, manual hydraulic tensioners were previously used. Basically, a team of6 peoplecan only produce; 1 wind turbine per day；a large wind power enterprise is using a robot bolt tensioner provided by Aerospace Intelligence. After the system and the bolt tension analysis software for supporting operations, at least2units are offline every day, and at the same time, the original manual blind drawing method and the unstable bolt data value are reduced.
Analysis of bolt tightening method
In the current industrial production, there are several methods for joining two parts together, such as welding, strapping, riveting, and screwing. This article mainly analyzes the applicationand solution of the screw connection method. The screw connection method is divided into the tightening screw connection method and the tensile screw connection method. Tightening screw connection method is commonly used on most bolts, but the tension method is more advantageous in the fastening method of large bolts.
The tightening methods developed by Aerospace Intelligence include high-precision intelligent hydraulic wrench tightening method and intelligent electric wrench tightening method.

The new technology high-precision intelligent floating bolt tensioner robot system developed by Aerospace Intelligence is currently at the international leading level; it completely solves the problems of short life of manual tensioners, low stretching accuracy, and unreliable stretching quality; Large bolts use the torque damage caused by the tightening method, and the tension method does not damage the bolt itself. At the same time, the bolts are extended and tightened more firmly.
Product features of intelligent hydraulic stretching system assembly
1. For the fastening of bolts above M36, the discrete torque of the bolt itself is smaller, and it is more in line with the Six Sigma standard;
2. The bolt extension can be recorded, and the tightening torque can be recorded and analyzed;
3. At present, the life of the stretch rod can be more than 15,000 times, and the life of the body is more than 50,000 times;
4. Sequential operations can be carried out in full accordance with the design process;
5. Mainly used in applications such as offshore wind turbine manufacturing, offshore equipment, nuclear power equipment, and petroleum pipelines.
