Description

Technical Field

[0001] The utility model belongs to the technical field of flange welding, and in particular relates to a magnetic suction type flange welding limiting correction tool. Background Art

[0002] In daily pipeline flange welding work, the flange welding angle is often incorrect or skewed, which directly affects the flange welding quality and the next step of pipeline installation. The reasons for this phenomenon are:

[0003] 1. Although the flange installation angle is adjusted with a square before welding, the flange angle changes again due to the tensile force of spot welding during positioning spot welding;

[0004] Second, the quality cannot be guaranteed if the spot welding is directly positioned by eyesight. Once it deviates, it needs to be aligned with hammer, which is time-consuming and laborious.

[0005] Therefore, based on long-term work experience and lessons, in order to avoid poor quality caused by angle deviation of flange during welding and reduce production costs and labor burden, after many tests and improvements, a magnetic flange welding limit correction tool was produced to pre-fix the flange during welding. Utility Model Content

[0006] The utility model aims to provide a magnetic flange welding limit correction tool to solve the problems of unstable welding and easy deviation of welding when the flange is welded on the pipeline proposed in the background technology.

[0011] Preferably, the outer surface of the thread sleeve is connected with a connecting plate, and at the same time, a plug-in component is provided through one end of the surface of the connecting plate.

[0012] Preferably, an auxiliary adjustment component is arranged on the left side of the back plate, and the auxiliary adjustment component includes a sleeve plate, and the sleeve plate is movably sleeved on the surface of the positioning pin, wherein an arc plate is arranged at one end of the sleeve plate.

[0013] Preferably, a limiting groove is provided at one end of the sleeve away from the arc plate, and a slide plate is connected to one end of the arc plate, wherein the inner surface of the slide plate is in sliding contact with the outer surface of the sleeve, and an abutment is provided through the surface of the slide plate.

[0014] Preferably, a stabilization component is arranged on the right side of the surface of the assembly shell, wherein the stabilization component includes stabilization arc plates symmetrically arranged at the front and rear ends of the assembly shell.

[0017] The utility model provides a magnetic suction flange welding limit correction tool with the following advantages:

[0018] The magnetic suction type flange welding limit correction tool is designed to be adsorbed and fixed at any position on the surface of the pipe body through the magnetism of the magnetic seat. The flange is against the pipe body and against the matching component connected to the magnetic seat. After three-point positioning by spot welding, the magnetic switch of the magnetic seat is turned off. After the tool is removed, the flange can be welded normally.
