Description

Technical Field

[0001] This utility model relates to the field of wind turbine support welding equipment, and in particular to a wind turbine support welding fixture. Background Technology

[0002] A fan is a machine that uses input mechanical energy to increase gas pressure and expel gas. Fans are widely used in factories, mines, tunnels, cooling towers, vehicles, ships, and buildings for ventilation, dust removal, and cooling; in boilers and industrial furnaces for ventilation and induced draft; in air conditioning equipment and household appliances for cooling and ventilation; in grain drying and conveying; as a wind source for wind tunnels; and for inflating and propelling hovercraft. A fan generally consists of a fan casing, an impeller, and a motor. The motor is located outside the fan casing, and the impeller is located inside. The motor's output shaft is driven by the impeller's rotating shaft. When the motor drives the impeller to rotate at high speed, it draws air from outside the fan casing into the fan casing and expels air from inside the fan casing, thus achieving air delivery.

[0003] Existing fan casings typically have a fan bracket for mounting the impeller. The bracket generally includes a central shaft and three legs, with one end of each leg fixedly connected to the outer wall of the central shaft via welding. The three legs are evenly distributed on the outer wall of the central shaft. However, due to the lack of corresponding welding fixtures, misalignment can easily occur during welding, affecting the product yield. Furthermore, the welding operation is difficult and inefficient.
