Description

Technical Field

[0001] The utility model relates to the technical field of automobile welding, in particular to an automobile intake pipe welding device. Background Art

[0002] Automobile intake pipes need to be seamlessly welded during the manufacturing process. Pipe fittings produced by seamless welding have the advantages of small deformation, strong crack resistance and good weld quality. The existing welding of automobile intake pipes mainly relies on manually prefabricated elbows and straight pipe sections, and then butt welding the pipelines on the work platform.

[0003] In the existing butt welding process of automobile intake pipes, the line arrangement and welding are mostly done manually according to the direction of the intake pipe to the engine. Therefore, the operation is cumbersome and requires high technical skills of the workers. In addition, the direction of the pipe needs to be constantly changed to align with the weld during welding, so the welding position is prone to unevenness. At the same time, since it is impossible to accurately simulate the direction from the intake port to one side of the engine during welding, the direction of the pipe after welding is prone to slight skew, which is not convenient for assembly. In view of this, in-depth research was conducted on the above-mentioned problems, and this case was created. Utility Model Content

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] See also Figure 1-3 The utility model provides an implementation scheme: in the welding process of modern automobile intake pipes, workers often connect multiple component pipes of the intake pipe by butt welding on a workbench. This method cannot determine the direction of the intake pipe, which is prone to welding deviation and requires fine-tuning during installation. Secondly, during the welding process, workers are required to flip the fixed base of the intake manifold back and forth, which makes the welding operation complicated and has high technical requirements.

[0021] In view of the above problems, the present application discloses an automobile intake pipe welding device, comprising a pair of L-shaped side frames 1, the pair of L-shaped side frames 1 are arranged opposite to each other, the corresponding points between the pair of L-shaped side frames 1 are welded together by at least one pair of cross-linking rods 2, and the pair of L-shaped side frames 1 and the cross-linking rods 2 are connected to the L-shaped side frames 1 to form a complete support frame structure, and the support frame is placed on a work surface when in use;

[0022] Furthermore, a pair of arc-shaped slideways 3 are welded on both side end points of a pair of L-shaped side frames 1, respectively. The pair of arc-shaped slideways 3 are arranged opposite to each other, and a pair of sliding blocks 4 are mounted on the pair of arc-shaped slideways 3. The pair of sliding blocks 4 slide along the pair of arc-shaped slideways 3, and the pair of sliding blocks 4 are limited by the pair of arc-shaped slideways 3. By adjusting the position of the sliding blocks 4, the position of the positioning plate 8 connected thereto is driven, and the position of the positioning plate 8 is adjusted. A plurality of positioning holes 9 are provided on the positioning plate 8, and the plurality of positioning holes 9 on the positioning plate 8 are used to fix the welding plate surface of the intake manifold pipe. When welding, first adjust the position of the positioning plate 8 so that the positioning plate 8 matches the installation position of one end of the intake manifold, and fix the base plate welded at one end of the intake manifold to the positioning plate 8 by bolts. A fixing plate 10 is connected between the opposite points at the bottom ends of a pair of L-shaped side frames 1. Both sides of the fixing plate 10 are separately connected to the pair of L-shaped side frames 1. The welded base plate at the other end of the intake manifold is fixed to the fixing plate 10 at the bottom end of the pair of L-shaped side frames 1. In this way, both sides of the intake pipeline are fixed according to the installation position. When welding, the pipe fittings of the intake manifold are butt-welded in sequence to complete the connection.

[0023] Furthermore, a pair of limiting grooves 5 are arranged along the direction of the slides on the pair of arc-shaped slides 3, and a pair of limiting bolts 6 are threadedly connected to the pair of sliding blocks 4. The pair of limiting bolts 6 pass through one side of the pair of limiting grooves 5. By rotating the pair of limiting bolts 6, the pair of limiting bolts 6 can move relative to the pair of sliding blocks 4, so that the pair of limiting bolts 6 are clamped on the outer side of the limiting grooves 5, so that the sliding blocks 4 and the limiting bolts 6 are relatively clamped and fixed on both sides of the limiting grooves 5, thereby fixing the position of the positioning plate 8. At the same time, a pair of rotating shafts 7 are arranged at the opposite ends of the pair of sliding blocks 4, and the positioning plate 8 is symmetrically connected between the pair of rotating shafts 7, so that the angle of the positioning plate 8 can be adjusted by the rotating shafts 7.

[0024] As a preferred solution, further, the pair of L-shaped side frames 1 are a pair of L-shaped steel plates, and a pair of placement plates 11 are arranged on the bottom edges of the pair of L-shaped side frames 1. The pair of placement plates 11 contact the work surface to support and stabilize the pair of L-shaped side frames 1.

[0025] As a preferred solution, further, the positioning plate 8 is a plate with a rectangular structure, and the two ends of the positioning plate 8 are respectively welded to the ends of a pair of rotating shafts 7, so that the positioning plate 8 and the pair of rotating shafts 7 become an integral plate.

[0026] As a preferred solution, further, a pair of positioning bolts are provided on one side of the rotating shaft 7 on the pair of sliding blocks 4, and the pair of positioning bolts are used to fix the angle of the pair of rotating shafts 7 and lock the angle of the positioning plate 8 after the adjustment of the positioning plate 8 is completed.

[0027] As a preferred solution, further, the pair of arc-shaped slideways 3 is a pair of arc-less plates with a rectangular cross-section.

[0028] As a preferred solution, further, at least one pair of fixing holes are symmetrically opened at both ends of the fixing plate 10, and locking holes are opened on the L-shaped side frame 1 corresponding to the fixing holes. Locking bolts 12 are installed through the locking holes and connected to the fixing holes, and the position of the fixing plate 10 is fixed by installing the locking holes and the locking bolts 12.

[0029] From the above, it can be generally known that the automobile intake pipe welding device movably installs the positioning plate 8 through the arc slide 3 on the L-shaped frame, and the position and angle of the positioning plate 8 can be adjusted. The positioning plate 8 and the fixing plate 10 respectively determine the two end positions of the automobile intake manifold, so that the pipe fittings are connected and welded in sequence, which not only facilitates the docking of the pipe fittings during welding, but also ensures that after the intake pipe welding is completed, the two ends of the intake pipe can accurately correspond to the installation position of the automobile engine.
