Problems solved by technology
After welding, the barrel section has large deformation and poor roundness. The turning process is complicated to adjust the roundness, and there is still unevenness of the turning bevel. After turning, it needs to be further polished manually. Therefore, the barrel section bevel is made manually
[0004] When the diameter of the barrel section is larger than 2000mm, the stroke of the existing manual beveling tool cannot meet the requirements
Considering the quality and safety factors, it can only be done manually with a small grinding gun
Manual beveling depends on the workers' processing experience, so the requirements for workers' skills are particularly high; during the process of beveling, the angle and depth need to be measured repeatedly, and the size of the barrel section is large, resulting in a long processing cycle; the fitter needs to manually grind the bevel after beveling mouth to ensure surface quality

The invention discloses a large deformed cylinder section manual rapid reverse welding groove device. The device comprises a handle and a connecting plate which are fixedly connected, the connecting plate is provided with an end face supporting plate, the end face supporting plate is fixedly connected with an arc-shaped supporting plate, the arc-shaped supporting plate is provided with rollers, the arc-shaped supporting plate is connected with an adjusting rod through a connecting bearing, and a guide support and an auxiliary guide support are arranged on the adjusting rod. The device replaces the operation that a worker holds a tool in a suspended mode, after the device and a manual tool are clamped, groove welding operation can be completed by rotating the device along a part by a circle, the problem that the surface quality is poor due to shaking is solved, and the labor intensity of the worker is reduced.
Description
technical field [0001] The invention relates to a large-scale deformed cylinder section manual rapid reverse welding groove device. Background technique [0002] Welding is an important method in the field of aerospace and aviation to connect the cylindrical parts of multiple parts. Before welding, welding grooves need to be made to ensure effective welding between the two parts. [0003] Inverted beveling can be performed by turning and manual methods. Inverting the welded bevel by turning is fast and efficient, and the surface quality of the bevel is good, but the turning method requires high roundness of the processed parts. After welding, the barrel section has large deformation and poor roundness. The turning process is complicated to adjust the roundness, and there is still uneven turning bevel. [0004] When the diameter of the barrel section is larger than 2000mm, the stroke of the existing manual beveling tool cannot meet the requirements. Considering quality and ...
