The special equipment for welding the inner corners of the U-shaped ribs is complex in structure, a welding gun tracking mechanism needs to be accurately aligned to a welding seam before welding, part of the mechanism is located at the front end of the welding gun, and at the beginning of welding, part of the mechanism suspends out of a panel, so that if no support is provided, the position deviation, tracking dislocation and welding gun deviation of the welding seam of the welding gun can be caused, and the welding quality is further influenced; if the support is provided, but the height difference exists between the support plate and the orthotropic bridge deck plate, the accuracy of the alignment position of the welding gun is also influenced, and the welding seam tracking dislocation is caused.
SUMMERY OF THE UTILITY MODEL
To prior art carrying out the problem of the welding seam tracking dislocation that exists among the U-shaped rib inside fillet weld welding process utilizing the special equipment of U-shaped rib inside fillet weld, the utility model provides a U-shaped rib inside fillet weld welding auxiliary device.
An auxiliary device for welding an inner side fillet weld of a U-shaped rib comprises a horizontal plate, two side plates oppositely fixed on the horizontal plate and a lapping piece fixed on the horizontal plate and extending to the side of a plate unit, wherein the flatness of the upper surface of the horizontal plate is less than 1mm/m, the upper sides of the side plates incline inwards, and the angles of the side plates are kept consistent with the angles of two side edges of the U-shaped rib;
when welding auxiliary device cooperation internal welding machine carries out the inboard fillet weld welding of U-shaped rib, attaching plate unit one side is placed, the horizontal plate upper surface flushes with the decking upper surface, curb plate laminating U-shaped rib both sides limit, overlap joint spare one side is fixed on the horizontal plate, and the overlap joint of the other side is on the decking.
Furthermore, one side of the horizontal plate, which is far away from the plate unit, is provided with a leveling mechanism, and the leveling mechanism can be bolts symmetrically arranged on the outer sides of the two side plates and penetrating through the horizontal plate.
Furthermore, the lap joint piece is provided with a semicircular notch near the contact surface of the horizontal plate and the bridge deck.
The utility model has the advantages that the installation is rapid and simple, the function of supporting the inner welding machine is realized, the welding gun can extend out of the U-shaped rib, the welding direction and angle of the welding gun can be adjusted by the operator outside the U-shaped rib, and a platform for the inner welding machine head to walk stably is provided at the beginning of welding, which is beneficial to improving the operation efficiency and the welding quality of the fillet weld at the inner side of the end part of the U-shaped rib; the semicircular notch can avoid the influence of the irregular edge of the bridge deck on the leveling effect of the horizontal plate.
Drawings
FIG. 1 is a schematic structural view of a fillet welding auxiliary device for the inner side of a U-shaped rib.
Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings and specific embodiments, and it is to be understood that the described embodiments are only some embodiments, but not all embodiments, of the present invention. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art all belong to the protection scope of the present invention.
Example 1
An auxiliary device for welding an inner side fillet weld of a U-shaped rib comprises a horizontal plate 1, two side plates 2 relatively fixed on the horizontal plate and a bridging piece 3 fixed on the horizontal plate and extending towards the plate unit side, wherein the upper sides of the side plates incline inwards and keep the same angle with the two side edges of the U-shaped rib, as shown in figure 1.
The horizontal plate, the side plate and the lap joint piece are all blanked from the steel plate and then machined, so that local materials are obtained, the structure is simple and practical, and the lap joint piece is easy to realize. The flatness of the upper surface of the horizontal plate is less than 1 mm/m.
When the auxiliary welding device is matched with an internal welding machine to weld the fillet weld on the inner side of the U-shaped rib, the auxiliary welding device and the plate unit are both placed on the workbench; welding auxiliary device attaching plate unit 4 one side is placed, 1 upper surface of horizontal plate flushes with the decking upper surface, 2 laminating U-shaped rib both sides limits of curb plate, 3 one side of overlap joint are fixed on horizontal plate 1, and the overlap joint of the other side is on the decking.
Whole welding auxiliary device installation is quick simple and convenient, plays the effect of supporting interior welding machine for welder can stretch out the U-shaped rib, and operating personnel can carry out the adjustment of welder welding direction and angle outside the U-shaped rib, and provides the platform that the welding machine aircraft nose steadily walked in supplying in the welding start phase, is favorable to improving the welding quality of operating efficiency and the inboard fillet weld of U-shaped rib tip.
In order to ensure that the upper surface of the horizontal plate is flush with the upper surface of the bridge deck, a leveling mechanism is arranged on one side, away from the plate unit, of the horizontal plate 1. One side of the horizontal plate is hung on the bridge deck, one side of the horizontal plate is supported by the leveling mechanism, and the side plate and two side edges of the U-shaped rib are always in a fit state, so that good stability can be guaranteed.
In this embodiment, the leveling mechanism is the bolts 5 symmetrically arranged on the outer sides of the two side plates and penetrating through the horizontal plate, and the bolts are threaded into the horizontal plate after tapping.
Because the bridge deck edge may be uneven, in this embodiment, the bridge deck has a semicircular notch near the contact surface between the horizontal plate and the bridge deck, as shown in fig. 1. The semicircular notch can avoid the influence of the irregular edge of the bridge deck on the leveling effect of the horizontal plate.
Finally, it should also be noted that the above list is only one specific embodiment of the present invention. Obviously, the present invention is not limited to the above embodiments, and many modifications are possible. All modifications which can be derived or suggested by a person skilled in the art from the disclosure of the invention should be considered as within the scope of the invention.
