[0050] In addition, the technical features involved in different embodiments of this application described below can be combined with each other as long as they do not conflict with each other.

[0051] An embodiment of the present invention provides a pipe beam welding tooling. Refer to Figure 1 As shown, the pipe beam includes: a pipe beam body 100, and two trailer hook connecting plates 101 respectively provided at the left and right end portions of the pipe beam body 100. Refer to Figure 2 As shown, the pipe beam welding tooling includes:

[0052] The seat body 1;

[0053] The first clamping assembly 2, having two, and the two first clamping assemblies 2 are arranged at intervals left and right on the seat body 1 for clamping the pipe beam body 100 during welding;

[0054] The second clamping assembly 3, there are two of them, and the two second clamping assemblies 3 are arranged at intervals on the seat body 1 from left to right, and are used to clamp two trailer hook connection plates 101 during welding.

[0055] It should be noted that the pipe beam in the embodiment of the present invention can be the front anti-collision beam or the rear anti-collision beam of the vehicle. In some alternative embodiments, the pipe beam can also be a structural member additionally provided on the front anti-collision beam, or a structural member additionally provided on the rear anti-collision beam. In the above embodiments, the pipe beam body 100 plays the role of providing support force and providing anti-impact force to resist impact.

[0056] The trailer hook connection plate 101 can be used for the connection between the pipe beam body 100 and the vehicle frame. After the connection, a trailer hook is provided on the pipe beam body 100, which can ensure that the trailer hook bears high traction force. In some alternative embodiments, the vehicle frame may include: a left side beam provided on the left side and extending along the vehicle length direction, and a right side beam provided on the right side and extending along the vehicle length direction.

[0057] In the embodiment of the present invention, by arranging two first clamping assemblies 2 at intervals on the seat body 1 from left to right, the pipe beam body 100 can be firmly clamped during welding, avoiding the interference of the displacement of the pipe beam body 100 during welding on the welding. Further, by arranging two second clamping assemblies 3 at intervals on the seat body 1 from left to right, the two trailer hook connection plates 101 can be firmly clamped during welding. The combination of the first clamping assembly 2 and the second clamping assembly 3 can ensure the relative position of the two trailer hook connection plates 101 with respect to the pipe beam body 100 is fixed, ensuring that the welded finished pipe beam has high dimensional accuracy and improving the welding yield.

[0058] In some embodiments of the present invention, optionally, refer to Figure 2 as shown, the first clamping assembly 2 includes:

[0059] A base 21, fixedly arranged on the seat body 1, and an opening groove 21a with an upward opening is formed at the top of the base 21;

[0060] A clamping seat 22, the lower end of the clamping seat 22 is fixedly connected to the seat body 1;

[0061] A clamping member 23, rotatably arranged at the upper end of the clamping seat 22 around a rotation center line extending in the left-right direction, and the clamping member 23 has a limiting groove (not shown in the figure);

[0062] The clamping member 23 has a first state and a second state relative to the base 21;

[0063] In the first state, the clamping member 23 approaches the base 21, and the limiting groove (not shown in the figure) and the opening groove 21a enclose a receiving chamber for receiving the pipe beam body 100. The receiving chamber is used to limit the circumferential displacement of the pipe beam body 100 when receiving the pipe beam body 100.

[0064] In the second state, the clamping member 23 is disengaged from the base 21.

[0065] It should be noted that in the first state, the clamping member 23 approaches the base 21, and the limiting groove (not shown in the figure) and the opening groove 21a enclose a receiving chamber for receiving the pipe beam body 100, that is, the first clamping assembly 2 clamps the pipe beam body 100. In the second state, the clamping member 23 is disengaged from the base 21, that is, the first clamping assembly 2 releases the clamping of the pipe beam body 100.

[0066] The above structure is simple, highly reliable, and can meet the clamping requirements of the pipe beam body 100.

[0067] In some embodiments of the present invention, optionally, refer to Figure 2 As shown, the first clamping assembly 2 further includes:

[0068] The first cylinder 24 is disposed on the seat body 1. The telescopic arm of the first cylinder 24 is rotatably connected to the clamping member 23. The first cylinder 24 is used to drive the clamping member 23 to switch between the first state and the second state.

[0069] By driving the clamping member 23 to rotate around the rotation center line extending in the left - right direction by the first cylinder 24, the clamping member 23 can be switched between the first state and the second state. The above setting can effectively reduce the heavy operation of manually rotating the clamping member 23. Especially on the industrial production line, the above setting can improve the welding efficiency and the yield rate of the welded finished pipe beam.

[0070] In some embodiments of the present invention, optionally, refer to Figure 2 As shown, the second clamping assembly 3 includes:

[0071] The first connecting seats 31 have two groups, which are fixedly arranged on the seat body 1, one on the left and one on the right;

[0072] The second connecting seats 32 have two groups, which are fixedly arranged on the seat body 1, one on the left and one on the right;

[0073] The second cylinder 33 is fixedly arranged on the second connecting seat 32;

[0074] On either side in the left - right direction, the telescopic arm of the second cylinder 33 can extend towards the direction close to the first connecting seat 31. The telescopic arm of the second cylinder 33 and the first connecting seat 31 form a clamping portion 34 for clamping the trailer hook connecting plate 101. When the telescopic arm of the second cylinder 33 extends, it abuts against the trailer hook connecting plate 101. The clamping portion 34 clamps the trailer hook connecting plate 101 to limit the displacement of the trailer hook connecting plate 101.

[0075] It should be noted that on either side in the left - right direction, the gap between the first connecting seat 31 and the second connecting seat 32 corresponds to the position of the trailer hook connecting plate 101 on the same side. That is to say, when welding is required, after the pipe beam is placed on the pipe beam welding tooling of the embodiment of the present utility model, the two trailer hook connecting plates 101 are respectively located in the gaps between the first connecting seat 31 and the second connecting seat 32 on the same side, that is, the two trailer hook connecting plates 101 are respectively located in the clamping portions on the same side. During welding, the user can operate the telescopic arm of the second cylinder 33 to extend. When the telescopic arm of the second cylinder 33 extends, it abuts against the trailer hook connecting plate 101 and clamps the trailer hook connecting plate 101, so that the positions of the two trailer hook connecting plates 101 relative to the pipe beam body 100 are fixed during welding, ensuring that the welded finished pipe beam has high dimensional accuracy and improving the welding qualified rate.

[0076] In some embodiments of the present utility model, optionally, refer to Figure 2 As shown, on one side of the upper end of the first connecting seat 31 close to the second cylinder 33, there is a limit seat 31a;

[0077] The limit seat 31a and the telescopic arm of the second cylinder 33 form the clamping portion 34.

[0078] In the embodiment of the present utility model, since the limit seat 31a is arranged on one side of the upper end of the first connecting seat 31 close to the second cylinder 33, when operating the clamping portion to clamp the trailer hook connecting plate 101, the stroke required for the telescopic arm of the second cylinder 33 to extend can be reduced. A short stroke is beneficial to improving the clamping execution efficiency and the welding efficiency.

[0079] In some embodiments of the present utility model, optionally, the pipe beam further includes:

[0080] Buffer beams 102, there are two of them, and the two buffer beams 102 are arranged at intervals left and right on the pipe beam body 100;

[0081] The upper end of the first connecting seat 31 further has a bearing seat 31b for receiving the buffer beam 102 during welding.

[0082] In the embodiments of the present utility model, the buffer beam 102 is used to offset part of the impact force through its own deformation when being impacted, avoiding the impact force directly acting on the pipe beam body 100, and effectively improving the structural strength of the pipe beam body 100. Thus, in practical applications, the buffer beam 102 often protrudes circumferentially from the pipe beam body 100. When welding the pipe beam using the embodiments of the present utility model, the buffer beam 102 is likely to interfere with the structural members on the pipe beam welding fixture. Since the upper end portion of the first connecting seat 31 further has a bearing seat 31b for accommodating the buffer beam 102 during welding, it can avoid the interference between the buffer beam 102 and the structural members on the pipe beam welding fixture, improve the welding success rate, and ensure the high dimensional accuracy of the pipe beam after welding.

[0083] In some embodiments of the present utility model, optionally, the pipe beam further includes:

[0084] Two guard plate brackets (not shown in the figure), which are arranged at intervals, one on the left and one on the right, on the pipe beam body 100;

[0085] See Figure 2 As shown, the pipe beam welding fixture includes:

[0086] Two support seats 4, which are arranged at intervals, one on the left and one on the right, on the seat body 1, and are used to support the guard plate brackets (not shown in the figure) during welding.

[0087] In some embodiments of the present utility model, optionally, see Figure 2 As shown, the seat body 1 has a plurality of lifting rings 5. Through the above arrangement, the user can use a lifting device to lift the pipe beam welding fixture of the embodiments of the present utility model, which is convenient for the transportation of the pipe beam welding fixture of the embodiments of the present utility model.

[0088] In some embodiments of the present utility model, optionally, see Figure 2 As shown, the bottom of the seat body 1 has a plurality of wheel assemblies 6 arranged at intervals. Through the above arrangement, the user can manually push or use a traction device to tow the pipe beam welding fixture of the embodiments of the present utility model for transportation on the ground, which is convenient for the transportation of the pipe beam welding fixture of the embodiments of the present utility model.

[0089] In some embodiments of the present utility model, optionally, the wheel assembly 6 is a universal wheel assembly. Through the above arrangement, the transportation convenience can be further improved.

[0090] The embodiments of the present utility model have been described above in conjunction with the accompanying drawings. However, the present utility model is not limited to the above specific embodiments. The above specific embodiments are merely illustrative and not restrictive. Under the inspiration of the present utility model, those of ordinary skill in the art can also make many forms without departing from the spirit and scope protected by the claims of the present utility model, and all of them fall within the protection scope of the present utility model.
