Description

Welding fixture for welding type shovel blade support

Technical Field

Background

The shovel blade of the land leveler is connected with the shovel blade and the land leveler through the supporting structure of the casting, most of the existing supporting structures are made of steel castings, but the steel castings are easy to go out of air hole defects, poor in angle positioning precision and the like in the casting process, so that the production cost of the steel castings is high, the strength of the steel castings is high, but the fatigue resistance effect is poor, and the phenomenon of supporting structure fracture is most likely to occur in long-term use. In order to solve this problem, it is necessary to manufacture a supporting structure from a steel sheet having excellent strength and fatigue resistance to reduce the production cost. However, the support structure made of steel plates has poor anti-winding effect, the structural strength of the support structure needs to be improved by using reinforcing ribs, the traditional reinforcing ribs are realized by means of bolts, riveting and the like, but a certain gap exists between the reinforcing ribs and the steel plates by adopting the connecting mode, and the gap can generate larger abrasion in the supporting process so as to reduce the service life, so the reinforcing ribs are preferably formed with the steel plates by adopting a welding mode, and the steel plates are plate-shaped, so the reinforcing ribs need to be formed on the side walls on two sides of the steel plates for ensuring the structural strength, and therefore welding work is required for ensuring the welding precision.
