Description

Technical Field

[0001] The utility model relates to the field of welding clamping auxiliary equipment, in particular to a horizontal directional drilling and riveting welding device. Background Art

[0002] Drill pipes, drive sleeves, connector plates, and baffles in horizontal directional drilling often require riveting. Riveting is a type of electric welding. The typical welding method involves penetrating the object with a welding rod. It is generally used to weld relatively thick metals. Riveting can be categorized into cold riveting and hot riveting. Cold riveting involves connecting with rivets, while hot riveting involves welding, which involves melting the two metals at high temperatures.

[0003] The welding of the drive sleeve and connecting plate in a drilling rig requires precise dimensional control and coaxial alignment to prevent deformation and other issues during the welding process. Currently, robotic welding is increasingly being used instead of manual welding. However, due to its structural characteristics, robotic arms are prone to tool chatter, making it difficult to ensure accurate welding. Maintaining workpiece stability is one way to mitigate tool chatter. To better apply mechanized welding to drilling rig welding, our company designed a specialized fixture for horizontal directional drilling riveting, improving welding efficiency and addressing these issues.
