Technical Field
[0001] This utility model relates to the field of anti-collision beam production technology, specifically to an automatic welding robot device for automobile anti-collision beam production. Background Technology
[0002] The continuous advancement of automotive engineering technology, especially the development of materials science and collision mechanics, has made it possible to diversify the design of crash beams. Engineers have begun to design crash beams of different shapes, sizes, and structures according to the characteristics and needs of different vehicle models. For example, in small cars, due to limited space, the design of crash beams focuses on minimizing volume and weight while ensuring energy absorption. Some small car crash beams use a hollow structure filled with energy-absorbing materials, such as foam plastic, which can effectively absorb and disperse energy during a collision. In contrast, the design of crash beams in large SUVs and off-road vehicles emphasizes strength and rigidity to cope with possible high-intensity collisions, and usually uses thicker high-strength steel or multi-layered crash beams.
[0003] In existing technologies, automated welding robots are one of the key pieces of equipment in the main production line of automobile manufacturing. They are used to weld various components of crash beams, such as welding the main steel beam of the crash beam to the reinforcing structure and connecting brackets. During the welding process, a large amount of radiation and spatter are generated. Without protection, this will affect the safety of workers. Moreover, crash beams come in different models, and the clamping device cannot automatically adapt to clamping different models and sizes of crash beams, which reduces the positional stability of the crash beam during the welding process.
[0004] Therefore, an automated welding robot device for the production of automotive anti-collision beams is proposed. Utility Model Content

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.
[0025] Example 1:
[0026] A preferred embodiment of the automatic welding robot device for producing automobile crash beams provided by this utility model is, for example... Figure 1-5 As shown: An automatic welding robot device for producing automotive anti-collision beams includes a frame 1, with legs 2 fixedly installed at equal intervals on both sides of the bottom of the frame 1, a protective component 3 provided at the bottom of the frame 1, an adaptive clamping component 4 provided on the surface of the protective component 3, a robotic arm 5 provided on the surface of the adaptive clamping component 4, and a welding head 6 fixedly installed on the surface of the robotic arm 5.
[0027] The protective component 3 specifically includes: a concave rod 311, which is fixedly installed at equal intervals on both sides of the bottom of the frame 1; a support platform 312, which is fixedly installed on the top of the concave rod 311; a threaded rod 313, which is rotatably connected to the bottom of the support platform 312; a motor 315, which is fixedly installed on the bottom of the frame 1; and a hollowed-out stabilizing plate 316, which is fixedly installed on the bottom of the frame 1.
[0028] The top of the support platform 312 is fixedly connected to the bottom of the robotic arm 5. The top of the support platform 312 extends into the interior of the frame 1. A pulley 314 is fixedly installed at the bottom of the threaded rod 313. A rotating rod 317 is rotatably connected to the inner wall of the hollow stabilizing plate 316. One end of the rotating rod 317 is fixedly connected to the output end of the motor 315. A pulley 318 is fixedly installed at the other end of the rotating rod 317.

[0031] In this example, the protective component 3 can be set up to protect the surroundings. The motor 315 is started to drive the rotating rod 317 and the second pulley 318 to rotate.

The working conditions can be observed through the radiation-proof glass 3113, and radiation can be protected at the same time, thereby achieving the protective function.
[0032] Example 2:
[0033] Based on Embodiment 1, a preferred embodiment of the automatic welding robot device for producing automotive anti-collision beams provided by this utility model is as follows: Figure 1-5As shown: The adaptive clamping assembly 4 specifically includes: a concave plate 411, fixedly installed on the top of the support platform 312; a groove 412, equidistantly opened on the top of the inner wall of the concave plate 411; a T-shaped groove 413, equidistantly opened on the top of the inner wall of the concave plate 411; a sliding groove 414, equidistantly connected on the top of the concave plate 411; an I-shaped block 415, slidably connected to the inner wall of the sliding groove 414; a clamping plate 4111, fixedly installed on the top of the I-shaped block 415; and U-shaped oil pipes 4112, equidistantly and evenly arranged on one side of the clamping plate 4111.
[0034] An electric push rod 416 is fixedly installed on the inner wall surface of the groove 412. A connecting block 417 is fixedly installed on the telescopic end of the electric push rod 416. A T-shaped block 418 is fixedly installed on the top of the connecting block 417. The outer wall of the T-shaped block 418 is slidably connected to the inner wall of the T-shaped groove 413. A connecting rod 419 is equidistantly connected to the bottom of the connecting block 417. The other end of the connecting rod 419 is movably connected to the bottom of the I-shaped block 415.
[0035] One side of the U-shaped oil pipe 4112 is connected to one side of the clamping plate 4111 and extends to the other side of the clamping plate 4111. Sealing gaskets 4113 are fixedly installed on the inner wall surface of the U-shaped oil pipe 4112. Pushing plates 4114 are fixedly installed between the inner walls of the U-shaped oil pipe 4112. Push rods 4115 are fixedly installed on one side of the pushing plates 4114. The other end of the push rods 4115 moves through the inside of the U-shaped oil pipe 4112 and the inside of the sealing gaskets 4113 and extends to the outside of the U-shaped oil pipe 4112. A positioning plate 4116 is fixedly installed on the other end of the push rods 4115. A rubber pad 4117 is fixedly installed on the other side of the positioning plate 4116.
[0036] In this example, different models of anti-collision beams are fixed by setting an adaptive clamping component 4. The electric push rod 416 is activated to drive the connecting block 417 to retract. The connecting block 417 drives one end of the connecting rod 419 to move. The other end of the connecting rod 419 will drive the I-shaped block 418 to move. Under the limiting action of the slide groove 414, the I-shaped block 418 moves inward, which further drives the clamping plate 4111, U-shaped oil pipe 4112, and positioning plate 4116 to fix the anti-collision beam. When encountering a curved surface, the corresponding positioning plate 4116 is pushed to retract. The positioning plate 4116 drives the pushing plate 4114 through the push rod 4115 to move, which pushes the hydraulic oil inside. The hydraulic oil will then drive another pushing plate 4114 to move, thereby achieving the effect of adaptive clamping.
[0037] Working principle: First, the anti-collision beam is placed between the positioning plates 4116. The electric push rod 416 is activated, causing the connecting block 417 to retract. The connecting block 417 slides stably within the T-slot 418 via the T-block 415. The connecting block 417 moves one end of the connecting rod 419, which in turn moves the I-block 418. Limited by the sliding groove 414, the I-block 418 moves inward, further driving the clamping plate. 4111, U-shaped oil pipe 4112, and positioning plate 4116 fix the anti-collision beam. The U-shaped oil pipe 4112 contains hydraulic oil. When it encounters a curved surface, it pushes the corresponding positioning plate 4116 to retract. Sealing gasket 4113 seals the pushing plate 4114. The positioning plate 4116, via push rod 4115, drives the pushing plate 4114, which in turn pushes the hydraulic oil inside. The hydraulic oil then drives another pushing plate 4114 to move. The anti-collision beam is fixed by the positioning plate 4116 driven by the push rod 4115. The rubber pad 4117 can buffer and protect the surface of the anti-collision beam. When it is necessary to protect the welding of the anti-collision beam, the motor 315 is started to drive the rotating rod 317 and the second pulley 318 to rotate. The hollow stabilizing plate 316 ensures the stable rotation of the rotating rod 317. The belt drives the first pulley 314 and the threaded rod 313 to rotate. The rotation of the threaded rod 313 further drives the cross thread block 319 and the protective frame 3111 to rise, protecting the area around the work area. The working situation can be observed through the radiation-proof glass 3113, and radiation protection can be provided at the same time. When the radiation-proof glass 3113 is damaged, a small gap is reserved between the two sides of the radiation-proof glass 3113 and the two sides of the inner wall of the convex groove 3112. The operator pushes the L-shaped positioning plate 3114 to move the two sides, and then the radiation-proof glass 3113 can be removed and replaced, thereby achieving the functions of protection and self-adaptive clamping.
[0038] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
