Description

Technical Field

[0001] This utility model relates to the field of automatic welding equipment technology, specifically to an automatic circumferential welder. Background Technology

[0002] The automatic circumferential welder is an advanced automated device designed for efficient and precise welding of circumferential welds on circular workpieces such as pipes and containers. This equipment integrates precision mechanical transmission, an intelligent control system, and high-performance welding technology, automatically completing workpiece clamping and positioning, rotation drive, and welding process control. Through preset welding parameters and programs, the automatic circumferential welder ensures uniform welds, effectively improving weld quality and reducing errors caused by human factors. Its high operating speed significantly improves production efficiency and reduces labor intensity, making it an indispensable piece of equipment in modern manufacturing.

[0003] The publication number CN211680636U discloses an automatic welding machine for circumferential and longitudinal seams of a water tank. It includes a power assembly, a moving clamping assembly, a lifting assembly, and an X-beam assembly and a Y-beam assembly mounted on a base. The X-beam assembly includes a guide rail 1 arranged along the axial direction of the water tank. The Y-beam assembly can move automatically along the guide rail 1. The Y-beam assembly includes a slide assembly and a guide rail 2 arranged radially along the water tank. The slide assembly can slide and adjust along the guide rail 2. The slide assembly includes a rocker arm for switching between circumferential and longitudinal seams, a rotary table for adjusting the tilt angle of the welding torch, a horizontal swing mechanism for driving the welding torch to reciprocate along the weld width direction, and a vertical adjustment mechanism for adjusting the vertical position of the welding torch. It offers good stability and convenient operation. However, this technology only has a single welding head. When double-sided welding is required, the single welding head needs to complete welding at one end before moving to the other end, resulting in low production efficiency. Therefore, this technology still has room for improvement. Summary of the Invention

[0004] The technical problem to be solved by this utility model is to provide an automatic circumferential seam welding machine to address the shortcomings of the prior art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an automatic circumferential seam welding machine, comprising a frame, the frame including a table, a crossbar provided on the table, a welding torch slidably connected to the crossbar, and a movable rotating head assembly capable of adjusting the relative position on the table.
