Description

Technical Field

[0001] This utility model relates to the field of tube sheet welding machine technology, specifically to an operating frame for a tube sheet welding machine head. Background Technology

[0002] The tube sheet welding head operating frame is a key piece of equipment used to fix and adjust the position of the welding torch for tube sheet welding. It mainly includes the head body, operating frame structure, control system, and cooling system. The operating frame for tube sheet welding heads is typically a rigid support, allowing for three-dimensional adjustment. Traditional tube sheet welding head operating frames have a large base and a stable chassis. To move and fix the operating frame, wheels and fixed feet are usually installed at the bottom. However, once the feet are fixed to the ground, it becomes inconvenient to move the operating frame. Therefore, adjusting the rotation of the operating frame is inconvenient during use. Adjustable and fixed rotation of the operating frame improves operational flexibility and convenience, meeting more operational needs when welding tube sheets in different positions and orientations. Therefore, we have further improved the operating frame, providing a tube sheet welding head operating frame. Utility Model Content
