Description

TECHNICAL FIELD

[0001] The utility model relates to a vertical flange welding processing device and belongs to the technical field of welding processing equipment. BACKGROUND

[0002] At present, when carrying out pipeline and flange plate welding operation, the axes of the flange and the pipeline are usually in parallel with the horizontal plane for welding. The current welding technology, equipment and tooling equipment can all meet the needs of welding operation, but in the welding operation, on the one hand, due to the weight of the pipeline and the flange equipment, it is difficult to position the flange and the pipeline before welding, and the positioning accuracy is also easily affected. In addition, during the welding operation, high temperature easily causes the metal structure between the flange and the pipeline to deform, and the gravity further reduces the processing accuracy of the welding operation and increases the difficulty of the welding operation. On the other hand, during the welding operation, the axes of the flange and the pipeline are parallel to the horizontal plane, which leads to the need for multiple welding processes such as flat welding, overhead welding and inclined welding when rotating around the pipeline axis for 360° range welding, resulting in high welding difficulty, low welding efficiency and serious impact on welding accuracy.

The positioning frame 41 and the bracket 42 are both circular arc shaped groove frame structures. The lower end surface of the positioning frame 41 is connected with the horizontal drive guide rail 2, and its axis is parallel to the axis of the bearing base 1. The outer side surface of the bracket 42 is hinged with the positioning frame 41 through the turnover mechanism 45, and the bracket 42 is rotated through the turnover mechanism 45 within the range of 0°-90°. The upper end surface of the bracket 42 is connected with a plurality of positioning clamps 44 distributed along its axis, and the axis of the positioning clamp 44 is parallel to the axis of the bracket 42. The laser light source 43 is connected with the bracket 42 through the adjusting mechanism 8. The laser light source 43 is parallel to the axis of the bracket 42, and when the bracket 42 is perpendicular to the axis of the positioning frame 41, the optical axis of the laser light source 43 is coaxial with the photosensitive sensor 5. The photosensitive sensor 5 is connected with the flange positioning table 3 and coaxially distributed;

[0022] In this embodiment, the drive circuit 6 is connected with the outer side surface of the bearing base 1, and is electrically connected with the horizontal drive guide rail 2, the flange positioning table 3, the photosensitive sensor 5, the turnover mechanism 45 of the bearing clamping groove 4 and the laser light source 43, respectively.

[0023] The flange positioning table 3 comprises a bracket 31, a bearing column 32, horizontal telescopic columns 33, pressure sensors 34, elastic pads 35 and a rotary drive mechanism 36. The bracket 31 is a plate-shaped structure with a rectangular cross section, and its outer side is connected to the inner side of the bearing base 1 through horizontal drive guide rails 2. The bracket 31 is provided with a guide hole 37 coaxially distributed therewith. The lower half of the bearing column 32 is embedded in the guide hole 37 and is coaxially distributed between the bearing column 32 and the guide hole 37. The lower end surface of the bearing column 32 is connected to the rotary drive mechanism 36, and the rotary drive mechanism 36 is connected to the lower end surface of the bracket 31. The upper end surface of the bearing column 32 is connected to the photosensitive sensor 5 and is coaxially distributed. There are at least three horizontal telescopic columns 33, which are evenly distributed around the axis of the bearing column 32 and are located above the upper end surface of the bracket 31. The rear end surface of each horizontal telescopic column 33 is connected to the outer side of the bearing column 32, and the axis of the horizontal telescopic column 33 is perpendicular to the axis of the bearing column 32.

The horizontal telescopic column, the pressure sensor and the rotary drive mechanism are electrically connected to the drive circuit.

[0024] The rotary drive mechanism can drive the bearing column and the horizontal telescopic columns connected to the bearing to rotate and adjust within a range of 360° during welding operation, thereby synchronously adjusting the position of the welding operation surface according to the needs of the welding operation, ensuring the control accuracy of the adjustment speed of the welding operation surface, effectively keeping the welding operation surface in the same stable horizontal plane, achieving welding process stability, improving welding efficiency and welding quality, and effectively reducing the difficulty of welding operation.

[0025] Meanwhile, the telescopic length of each horizontal telescopic column can be adjusted so that the elastic pad directly abuts against the inner surface of the flange to be welded, effectively meeting the needs of positioning flanges of different structures. During welding operation with the pipeline to be welded, the elastic pad also abuts against the inner surface of the pipeline to be welded to clamp and position the pipeline to be welded. The pressure between each horizontal telescopic column and the flange can be detected by the pressure sensor, thereby ensuring the stability and uniformity of the force of the flange positioning. When the flange and the pipeline to be welded are deformed due to high temperature during welding, the horizontal telescopic column and the elastic pad can be used to forcibly position the flange to overcome the decrease in welding precision caused by deformation.

At the same time, a positioning pin 444 is provided on the slider 443, and the slider 443 is connected to the bracket 42 through the positioning pin 444.

[0027] During welding operations, each positioning fixture first adjusts the working position of the overall equipment by using a slider. Then, the telescopic drive column adjusts the distance between the left and right halves of the clamp to effectively clamp the pipe and position it. At the same time, the telescopic drive column provides auxiliary clamping and positioning force to the clamp, improving the stability of the pipe positioning.

[0028] In a further optimized configuration, the horizontal telescopic column 33 and the telescopic drive column 441 are either electric telescopic columns, hydraulic telescopic columns, or pneumatic telescopic columns.

One connecting base 83 covers the slide bar 7 and is slidably connected to the slide bar 7 through the elastic clamp 84. The other connecting base 83 is covered by the laser light source 43 through the elastic clamp 84. The two connecting bases 43 are connected to each other by the scissor telescopic arm 81. The axis of the scissor telescopic arm 81 is perpendicular to and intersects the axis of the support groove 42. A level 82 is also provided on the scissor telescopic arm 81. In addition, the scissor telescopic arm 81 and the level 82 are electrically connected to the drive circuit 6.

[0031] Through the slide, the distance between the adjusting mechanism, the laser light source connected with the adjusting mechanism and the pipeline to be welded can be flexibly adjusted, and the laser light source, the pipeline to be welded and the photosensitive sensor are simultaneously arranged in a coaxial distribution state through the setting of the scissor telescopic arm, so that the workpiece welding positioning adjustment is achieved.

[0032] In addition, a welding machine 9 and a flow guide fan 10 are additionally arranged in the bearing base 1, and the welding machine 9 and the flow guide fan 10 are slidably connected with the bottom of the bearing base 1 through slide rails 11, and the welding machine 9 and the flow guide fan 10 are arranged on both sides of the flange positioning table 3, and the flow guide fan 10 is additionally provided with a flow guide air pipe 12 outside, the axis of the flow guide air pipe 12 is at an angle of 0°-60° with the axis of the bearing base 1, and the flow guide fan 10 is connected with the flange positioning table 3 through the flow guide air pipe 12, and the axis of the flow guide fan 10 is located 1-20 cm below the upper end surface of the flange positioning table 3 and intersects with the axis of the flange positioning table 3, and the welding machine 9 and the flow guide fan 10 are electrically connected with the driving circuit 6.

[0033] The setting of the welding machine can be directly used for welding operation, and the smoke generated in the welding process is collected and recycled through the flow guide fan and the flow guide air pipe, so as to reduce the pollution caused by welding smoke.
