AI Technical Summary
The current intercooler tube welding requires two people to work together, which leads to wasted manpower and low work efficiency, and manual operation affects the welding quality.
Design a welding fixture for intercooler tubes, including a welding worktable, an internal clamping device, and an elbow fixing bracket. The internal clamping device is rotated by a ball screw transmission mechanism and a rotating shaft to achieve 360° welding of straight tubes, reducing manual operation and improving welding quality and efficiency.
It enables efficient welding by a single operator, improves welding quality and output, saves labor costs, and ensures a stable and smooth welding process.
