Description

Technical Field

[0001] This utility model relates to the field of automatic welding machine technology, specifically a vertical circumferential seam automatic welding machine. Background Technology

[0002] An automatic circumferential welder is a general-purpose automatic welding device capable of completing various circular and circumferential welds. It can be used for high-quality welding of materials such as carbon steel, low-alloy steel, stainless steel, aluminum, and their alloys.

[0003] A search revealed that patent application number 202420480160.X discloses a vertical automatic circumferential seam welding machine, comprising a work platform, two mounting frames, an XZ linear dual-axis moving platform, and an electric welding machine. The mounting frames move along the Y-axis on the work platform, and the XZ linear dual-axis moving platform drives the electric welding machine to move along the X and Z axes. The design adds a long, narrow work platform to accommodate two mounting frames and their three-jaw chucks. After the three-jaw chucks hold the workpiece to be processed, the two mounting frames can alternately pass through the processing area of ​​the automatic welding gun to complete the processing. After welding, one mounting frame is moved to a safe position, allowing the processed workpiece to be removed or a new workpiece to be processed to be placed back in, resulting in high efficiency and safety in workpiece loading and unloading. Simultaneously, the other mounting frame, the three-jaw chuck, and the workpiece are moved to the processing area of ​​the automatic welding gun, significantly reducing the idle time of the automatic welding gun and improving welding efficiency.

[0004] The aforementioned application document uses a three-jaw chuck on the bottom side to limit the circular steel pipe on the top side, but it cannot perform corresponding welding between different steel pipe ends. How to limit different steel pipes to ensure subsequent automatic welding has become an urgent problem to be solved.

[0005] Therefore, we propose a vertical automatic circumferential welder. Utility Model Content

[0011] As a preferred embodiment of this utility model, a lead screw shaft is assembled on the inner side wall of the slide groove, and a lead screw cylinder fitted on the lead screw shaft is fixedly mounted in the middle of the slide block.

[0012] The lead screw cylinder is designed to facilitate the left and right movement of the lead screw shaft rotation adjustment limit assembly on the worktable, ensuring the adjustment effect.

[0014] The bearing ring is designed to allow the lead screw shaft to rotate freely under drive.

[0015] As a preferred embodiment of this utility model, the support piece is an arc-shaped piece, and the outer wall of the support piece is tightly attached to the inner wall of the pipe port;

[0016] The support plate is designed to provide external support and limit the pipe from the inside at the pipe end, ensuring the stability of the pipe body.

[0017] As a preferred embodiment of this utility model, four sets of L-shaped frames are fixedly installed at the four corners of the bottom of the workbench, and two sets of support seats located between two sets of limiting components are fixedly installed on the top of the workbench. The two sets of support seats are arranged on both sides of the automatic welding head, and the support seats include a vertical welding plate on the bottom side and an arc-shaped welding plate on the top.
