Description

Technical Field

[0001] This invention relates to the field of welding technology, specifically a welding device for processing the crossbeam of a dashboard in a new energy vehicle. Background Technology

[0002] The instrument panel crossbeam assembly is located inside the instrument panel and provides support for the instrument panel trim assembly and its accessories (such as radio, CD player, air conditioning control module, instrument cluster, etc.), passenger side airbag (PAB), steering column (sometimes including chassis parts such as brake pedal, accelerator pedal, clutch pedal, etc.), air conditioning box, wiring harness and other parts. It also serves as an auxiliary fixture and positioning support structure during the assembly process of the modular instrument panel assembly.

[0003] Sheet metal welded beams can be divided into box-type tube beams and column-type tube beams according to the shape of the beam end face. Box-type tube beams are inferior in strength and rigidity compared to column-type beams of the same material, while column-type beams are widely used due to their obvious price and performance advantages.

[0004] Based on the shape of the tubes, tubular crossbeams can be divided into straight tubes and bent tubes. Bent tubes are relatively advantageous for the spatial arrangement of cockpit system components, but they also weaken the structure and safety performance, are more complex to manufacture, have poorer dimensional stability, and are more expensive. Straight tubes, on the other hand, are very advantageous for structure and safety performance, and their production and manufacturing are relatively easier to control, thus their cost is relatively lower. In the production of straight tube crossbeams, the welding positions are close together, which causes the welding heat to accumulate, resulting in local deformation of the tube beam and affecting the quality of the product.

[0005] To address the aforementioned issues, we have made improvements by proposing a welding device for processing the crossbeam of a new energy vehicle dashboard. Summary of the Invention

Detailed Implementation

[0033] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0034] Example 1:

[0035] like Figure 1 - Figure 8As shown, a welding device for processing the crossbeam of a new energy vehicle dashboard includes a support column 1. A rotary motor 15 is fixedly installed on the top of the support column 1. A load-bearing rod 7 is fixedly installed at the output end of the rotary motor 15. A pipe beam 8 is sleeved on the outer side of the load-bearing rod 7. A welding robotic arm 2 and a feeding robotic arm 3 are respectively installed on the front and rear sides of the load-bearing rod 7. Multiple fixing plates 11 are arranged in a circumferential array on the outer side of the load-bearing rod 7, and the outer wall of the fixing plates 11 is in contact with the inner wall of the pipe beam 8. A supporting mechanism is provided between the fixing plates 11 and the load-bearing rod 7. A support is provided on the left side of the load-bearing rod 7. The mechanism includes a displacement mechanism at the bottom of the support mechanism, multiple springs 24 between the fixed plate 11 and the load-bearing rod 7, a disc 18 fixedly connected to the right side of the load-bearing rod 7, multiple straight rods 19 arranged in a circumferential array on the left side of the disc 18, and the straight rods 19 overlap with the pipe wall of the pipe beam 8. A feeding device is provided on the left side of the load-bearing rod 7, and the pipe beam 8 is fed onto the load-bearing rod 7 along the feeding device. An avoidance mechanism is installed at the bottom of the feeding device to allow the feeding device to be misaligned with the load-bearing rod 7, so as to avoid interference between the pipe beam 8 and the feeding device during the unloading process after the crossbeam is welded.

[0036] Under the action of the feeding equipment, the pipe beam 8 is installed on the outside of the load-bearing rod 7. The displacement mechanism works to support the left end of the load-bearing rod 7 and push the supporting mechanism and the pipe beam 8 to the right until the right end of the supporting mechanism on the right side of the load-bearing rod 7 and the right end of the pipe beam 8 abut against the disc 18 and the straight rod 19 respectively. As the supporting mechanism moves to the right, the supporting mechanism opens, and the fixing plate 11 abuts against the inner wall of the pipe beam 8, fixing the pipe beam 8 on the outside of the load-bearing rod 7. During the welding process, the welding positions are close together, which causes the welding heat to accumulate. The supporting fixing plate 11 acts on the inner wall of the pipe beam 8 to support the pipe wall of the pipe beam 8 and fix the shape of the pipe wall to prevent the pipe beam 8 from deforming due to heat accumulation. After the welding is completed, under the action of the spring 24, the fixing plate 11 moves towards the load-bearing rod 7 to facilitate the unloading of the pipe beam 8.

[0037] Further reference Figure 1 , Figure 4 and Figure 7 The fixed plate 11 has a cavity inside, and a partition 23 is installed inside the cavity. There is a gap between the left end of the partition 23 and the inner wall of the cavity. A pair of connecting pipes 20 are installed at the right end of the cavity. The pair of connecting pipes 20 are connected to the input end and the output end of the cooling equipment, respectively. During the welding process, the cooling equipment delivers coolant to the cavity inside the fixed plate 11 through the connecting pipes 20. The coolant flows in the cavity in a U-shaped path. The fixed plate 11 is in contact with the inner wall of the pipe beam 8. Heat is transferred to the coolant in the cavity. The coolant carries away excess heat to avoid heat accumulation and deformation of the pipe beam 8.

[0038] Furthermore, such as Figure 8As shown, the end face of the fixing plate 11 has several stepped holes 25. A heat-conducting block 26 is movably disposed inside each stepped hole 25. A connecting rubber 27 is fixedly connected to the bottom end of the heat-conducting block 26, and the connecting rubber 27 is fixedly connected to the inner wall of the chamber. The connecting rubber 27 has a deformation allowance, and the connecting rubber 27 is sealed to both the heat-conducting block 26 and the inner wall of the chamber. The surface material of the fixing plate 11 at the positions offset from the stepped holes 25 is rough, and these surfaces are coated with a wear-resistant coating. Of the two connecting pipes 20, the inner diameter of the connecting pipe 20 entering the chamber is greater than... As the coolant flows into the chamber, the inner diameter of the connecting pipe 20 output from the chamber causes the pressure inside the chamber to gradually increase. This increased pressure pushes the heat-conducting block 26 upward along the stepped hole 25, causing the heat-conducting block 26 to protrude from the fixing plate 11 and fit against the inner wall of the pipe beam 8. Using different materials on the surface of the fixing plate 11 increases the friction between the fixing plate 11 and the inner wall of the pipe beam 8, making the pipe beam 8 more firmly fixed on the load-bearing rod 7. It also allows the heat-conducting block 26 to retract into the stepped hole 25, reducing wear on the heat-conducting block 26 and extending the service life of the device.

[0039] Specifically, such as Figure 1 and Figure 2 As shown, there are two supporting mechanisms, which are respectively set on the left and right sides of the load-bearing rod 7. Each supporting mechanism includes a connecting sleeve 9, which is slidably connected to the outside of the load-bearing rod 7. Multiple push rods 10 are arranged in a circumferential array on the outside of the connecting sleeve 9, and the ends of the push rods 10 are hinged to the fixed plate 11. Two connecting sleeves 9 are set in one supporting mechanism, which are arranged laterally along the load-bearing rod 7. The two connecting sleeves 9 are connected by a connecting rod 22. The supporting mechanism and the disc 18 cooperate to make the connecting sleeves 9 on both sides move towards each other, thereby increasing the angle between the push rod 10 and the horizontal plane, and thus making the fixed plate 11 move away from the load-bearing rod 7 until it fits against the inner wall of the pipe beam 8. Two connecting sleeves 9 are set on each side and are connected by a connecting rod 22 to support the fixed plate 11 from multiple positions, thereby improving the stability of the fixed plate 11.

[0040] Specifically, such as Figure 1 , Figure 2 and Figure 5As shown, the support mechanism includes a mounting block 5. A first telescopic electric cylinder 6 is fixedly connected to the top of the mounting block 5. A U-shaped plate 12 is fixedly connected to the top of the first telescopic electric cylinder 6. A semi-circular tube 13 is provided inside the U-shaped plate 12, and the end of the semi-circular tube 13 is sleeved on the outside of the connecting sleeve 9. The semi-circular tube 13 cooperates with the load-bearing rod 7. A plurality of guide posts 14 are fixedly connected to the right end of the semi-circular tube 13, and the guide posts 14 penetrate to the left side of the U-shaped plate 12. A second telescopic electric cylinder 21 is fixedly installed at the bottom left side of the U-shaped plate 12, and the output end of the second telescopic electric cylinder 21 is fixedly connected to the semi-circular tube 13. The semi-circular tube 13 supports the load-bearing rod 7, and the semi-circular tube 13 is fixedly connected to the bottom left side of the U-shaped plate 12. The connecting sleeve 9 at the left end abuts against the second telescopic electric cylinder 21, which pushes the semi-circular tube 13 so that the semi-circular tube 13 acts on the connecting sleeve 9, thereby causing the fixing plate 11 to abut against the inner wall of the pipe beam 8. The upper part of the U-shaped plate 12 expands outward. When the pipe beam 8 is installed on the load-bearing rod 7, the U-shaped plate 12 moves to the lower middle part of the load-bearing rod 7 to support the pipe beam 8, reduce the friction between the inner wall of the pipe beam 8 and the fixing plate 11, and extend the service life of the fixing plate 11. The inner wall of the U-shaped plate 12 is provided with a rubber pad so that the U-shaped plate 12 can clamp the outer wall of the pipe beam 8. The U-shaped plate 12 can act on the outside of the pipe beam 8 and drag the pipe beam 8 to assist in feeding.

[0041] Furthermore, such as Figure 1 and Figure 3 As shown, the displacement mechanism includes a guide rail 16, which is slidably mounted on the bottom of the mounting block 5. The guide rail 16 extends toward the support column 1. A drive motor 17 is fixedly mounted on the left end of the guide rail 16. A threaded rod 4 is fixedly connected to the output end of the drive motor 17, and the outer side of the threaded rod 4 is threadedly connected to the mounting block 5. When the drive motor 17 works, it drives the threaded rod 4 to rotate. The rotating threaded rod 4 drives the mounting block 5 through the thread, thereby causing the first telescopic electric cylinder 6 and the U-shaped plate 12 to move left and right.

[0042] Example 2:

[0043] The difference from Embodiment 1 is that, as Figure 9 and Figure 10 As shown, the outer diameter of the load-bearing rod 7 increases from left to right. The fixing plate 11 is stepped, so that the distance from the outer surface of the load-bearing rod 7 to the bottom surface of the fixing plate 11 is constant. The U-shaped plate 12 is stepped, and the inner diameter of the U-shaped plate 12 increases from bottom to top. Straight pipe beams are divided into two types: constant diameter and variable diameter. The advantage of variable diameter straight pipes is that they reduce the weight of the parts and increase the arrangement space on the passenger side. When welding the variable diameter pipe beam 8, the load-bearing rod 7 is set as a variable diameter load-bearing rod 7 that changes with the variable diameter pipe beam 8, and the fixing plate 11 is set as stepped to fit the inner wall of the variable diameter pipe beam 8, so that the welding device can weld the variable diameter pipe beam 8. The stepped U-shaped plate 12 can act on the non-passage position of the variable diameter pipe beam 8 and support it.

[0044] Working principle: The pipe beam 8 moves along the feeding equipment towards the load-bearing rod 7. When the pipe beam 8 partially overlaps with the load-bearing rod 7, the first telescopic electric cylinder 6 operates, causing the U-shaped plate 12 to cover the outside of the pipe beam 8 and lift it. The pipe beam 8 continues to move to the right. At this time, the drive motor 17 operates, driving the threaded rod 4 to rotate. The rotating threaded rod 4 causes the mounting block 5 to move to the right, thereby causing the U-shaped plate 12 to drag the pipe beam 8, assisting in feeding, until the right end of the pipe beam 8 abuts against the straight rod 19. The first telescopic electric cylinder 6 retracts, causing the U-shaped plate 12 to pull the pipe beam 8. When plate 12 separates from tube beam 8, U-shaped plate 12 returns to the left end of load-bearing rod 7 under the action of displacement mechanism. First telescopic electric cylinder 6 extends, so that semi-circular tube 13 supports the left end of load-bearing rod 7. Then, displacement mechanism works to make U-shaped plate 12 move to the right until it abuts against the left end of tube beam 8. At this time, second telescopic electric cylinder 21 works to make semi-circular tube 13 move to the right and push connecting sleeve 9, so that push rod 10 acts on fixed plate 11, so that fixed plate 11 fits against the inner wall of tube beam 8 and fixes tube beam 8.

[0045] At this time, the feeding robotic arm 3 and the welding robotic arm 2 are working, and the rotating motor 15 is working to adjust the position of the pipe beam 8 and weld the parts onto the surface of the pipe beam 8.

[0046] During the welding process, the cooling equipment inputs coolant into the chamber inside the fixed plate 11. The coolant flows along the chamber. Due to the different diameters of the two connecting pipes 20, the pressure inside the chamber increases, pushing the heat-conducting block 26 out of the stepped hole 25, so that the heat-conducting block 26 contacts the inner wall of the tube beam 8. The flowing coolant carries away the excess heat during welding, preventing heat accumulation from causing deformation of the tube beam 8. Furthermore, when the fixed plate 11 supports the tube beam 8, it maintains the shape of the tube beam 8, further preventing deformation of the tube beam 8.

[0047] After welding is completed, the U-shaped plate 12 retracts, and the spring 24 causes the fixing plate 11 to move towards the load-bearing rod 7, thus losing its fixing effect on the pipe beam 8, and the welded pipe beam 8 can be removed.

[0048] Finally, it should be noted that the above descriptions are merely preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention 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 the present invention should be included within the protection scope of the present invention.
