Description

Technical Field

[0001] The present invention relates to the technical field of welding, and particularly to a welding device for processing the instrument panel crossbeam of a new energy vehicle. Background Art

[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 radios, CD players, air conditioning control modules, combination meters, etc.), the passenger-side airbag (PAB), the steering column (sometimes including chassis parts such as brake pedals, accelerator pedals, and clutch pedals), the air conditioning box, wiring harnesses, etc. At the same time, it is also a structural part for auxiliary jigs and positioning supports during the assembly of the modular instrument panel assembly.

[0003] Sheet metal welded crossbeams can be divided into box-shaped tube beams and pipe column-shaped tube beams according to the shape of the crossbeam end face. Compared with pipe column-shaped beams of the same material, box-shaped tube beams are inferior in terms of strength and stiffness. Due to their obvious price and performance advantages, pipe column-shaped crossbeams are widely used.

[0004] Pipe column-shaped crossbeams can be divided into straight pipe types and bent pipe types according to the shape of the pipes. The bent pipe type is relatively beneficial for the layout of the parts space of the cockpit system, but it will also weaken the structural and safety performance, be more complex to manufacture, have poor dimensional stability, and be more costly. The straight pipe type is very beneficial for structural and safety performance, and the production and manufacturing are relatively easy to control, so the cost is relatively low. In the production of straight pipe type crossbeams, the welding positions are relatively close, resulting in the accumulation of welding heat, causing local deformation of the tube beam and affecting the product quality.

[0005] In order to solve the above problems, we have made improvements and proposed a welding device for processing the instrument panel crossbeam of a new energy vehicle. Summary of the Invention

Detailed implementation manners

[0033] The following describes the preferred embodiments of the present invention with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are only for the purpose of illustrating and explaining the present invention, and are not used to limit the present invention.

[0034] Embodiment 1:

[0035] As Figure 1 - Figure 8As shown, a welding device for processing a cross beam of an instrument panel of a new energy vehicle comprises a support column 1, a rotating motor 15 is fixedly installed on the top of the support column 1, a load-bearing rod 7 is fixedly installed on the output end of the rotating motor 15, a pipe beam 8 is sleeved on the outer side of the load-bearing rod 7, a welding robot arm 2 and a feeding robot arm 3 are respectively installed on the front and rear sides of the load-bearing rod 7, a plurality of 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 plate 11 is in contact with the inner wall of the pipe beam 8, a supporting mechanism is arranged between the fixing plate 11 and the load-bearing rod 7, and a supporting mechanism is arranged on the left side of the load-bearing rod 7. Mechanism, a displacement mechanism is arranged at the bottom of the supporting mechanism, a plurality of springs 24 are arranged between the fixed plate 11 and the load-bearing rod 7, a disc 18 is fixedly connected to the right side of the load-bearing rod 7, a plurality of straight rods 19 are installed along the circumferential array on the left side of the disc 18, and the straight rods 19 coincide with the pipe wall of the pipe beam 8, a feeding device is arranged on the left side of the load-bearing rod 7, the pipe beam 8 is sent to the load-bearing rod 7 along the feeding device, and an avoidance mechanism is installed at the bottom of the feeding device, so that the feeding device can be displaced 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 cross beam welding is completed;

[0036] The pipe beam 8 is installed to the outside of the load-bearing rod 7 under the action of the feeding equipment. The displacement mechanism works to make the supporting mechanism support the left end of the load-bearing rod 7, and the propping mechanism pushes the propping mechanism and the pipe beam 8 to the right, until the propping mechanism on the right side of the load-bearing rod 7 and the right end of the pipe beam 8 are respectively against the disc 18 and the straight rod 19. As the supporting mechanism moves to the right, the propping mechanism opens, and then the fixing plate 11 is against the inner wall of the pipe beam 8, so that the pipe beam 8 is fixed on the outside of the load-bearing rod 7. During the welding process, the welding positions are close to each other, so that the welding heat accumulates. The propped fixing plate 11 acts on the inner wall of the pipe beam 8, supports the pipe wall of the pipe beam 8, fixes the shape of the pipe wall, and avoids deformation of the pipe beam 8 due to heat accumulation. After the welding is completed, under the action of the spring 24, the fixing plate 11 moves toward the load-bearing rod 7 to facilitate the unloading of the pipe beam 8.

[0037] For further reference, Figure 1 , Figure 4 and Figure 7 A chamber is provided inside the fixed plate 11, a partition 23 is provided inside the chamber, and a gap is left between the left end of the partition 23 and the inner wall of the chamber, a pair of connecting pipes 20 are installed at the right end of the chamber, and the pair of connecting pipes 20 are respectively connected to the input end and the output end of the cooling device. During the welding process, the cooling device transports coolant to the chamber in the fixed plate 11 through the connecting pipe 20, and the coolant flows in the chamber in a U-shaped path. The fixed plate 11 fits the inner wall of the tube beam 8, and the heat is transferred to the coolant in the chamber. The coolant takes away excess heat to avoid heat accumulation and deformation of the tube beam 8.

[0038] Further, such as Figure 8As shown, the end surface of the fixed plate 11 is provided with a plurality of stepped holes 25, and a heat conducting block 26 is movably arranged inside the 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, and the connecting rubber 27 is provided with a deformation margin, and the connecting rubber 27 is sealedly connected to the heat conducting block 26 and the inner wall of the chamber. The surface material of the position of the fixed plate 11 staggered from the stepped hole 25 is rough, and the surface of these positions is provided with a wear-resistant coating. Among the two connecting pipes 20, the inner diameter of the connecting pipe 20 input into the chamber is greater than The inner diameter of the connecting pipe 20 output from the chamber, when the coolant flows into the chamber, due to the difference in pipe diameters, the pressure in the chamber will gradually increase, and the increased pressure will push the heat conductive block 26 upward along the stepped hole 25, so that the heat conductive block 26 protrudes from the fixed plate 11 and fits against the inner wall of the pipe beam 8, and the surface of the fixed plate 11 is made of different materials, which increases the friction between the fixed plate 11 and the inner wall of the pipe beam 8, so that the pipe beam 8 is more firmly fixed on the load-bearing rod 7, and the heat conductive block 26 can be retracted into the stepped hole 25, thereby reducing the wear of the heat conductive block 26 and extending the service life of the device.

[0039] Specifically, Figure 1 and Figure 2 As shown, there are two supporting mechanisms, which are respectively arranged on the left and right sides of the load-bearing rod 7. The supporting mechanism includes a connecting sleeve 9, and the connecting sleeve 9 is slidably connected to the outside of the load-bearing rod 7. A plurality of push rods 10 are arranged along 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 arranged in one supporting mechanism, and the two connecting sleeves 9 are arranged horizontally 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 thereby making the fixed plate 11 move away from the load-bearing rod 7 until it fits with the inner wall of the pipe beam 8. Two connecting sleeves 9 are arranged on each side and are connected by a connecting rod 22, so as to support the fixed plate 11 from multiple positions and improve the stability of the fixed plate 11.

[0040] Specifically, Figure 1 , Figure 2 and Figure 5As shown in the figure, the support mechanism includes a mounting block 5. A first telescopic electric cylinder 6 is fixedly connected to the top end of the mounting block 5. A U-shaped plate 12 is fixedly connected to the top end of the first telescopic electric cylinder 6. A semi-circular tube 13 is arranged 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 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 abuts against the leftmost connecting sleeve 9. When the second telescopic electric cylinder 21 works to push the semi-circular tube 13, the semi-circular tube 13 acts on the connecting sleeve 9, so that the fixing plate 11 abuts against the inner wall of the pipe beam 8, and the upper half 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 part of the middle 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. A rubber pad is arranged on the inner wall of the U-shaped plate 12, so that the U-shaped plate 12 can clamp the outer wall of the pipe beam 8, and 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] Further, as Figure 1 and Figure 3 shown, the displacement mechanism includes a guide rail 16, and the guide rail 16 is slidably installed at the bottom of the mounting block 5. The guide rail 16 extends towards the support column 1. A driving motor 17 is fixedly installed at the left end of the guide rail 16. The output end of the driving motor 17 is fixedly connected to a threaded rod 4, and the outside of the threaded rod 4 is threadedly connected to the mounting block 5. When the driving motor 17 works to drive the threaded rod 4 to rotate, the rotating threaded rod 4 drives the mounting block 5 through the thread, so that the first telescopic electric cylinder 6 and the U-shaped plate 12 move left and right.

[0042] Embodiment 2:

[0043] The difference from Embodiment 1 is that, as Figure 9 and Figure 10 shown, the outer diameter of the load-bearing rod 7 gradually 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 gradually increases from bottom to top. The straight pipe-shaped pipe beam is divided into two types: equal diameter and variable diameter. The advantage of the variable diameter straight pipe is that it reduces the weight of the parts and increases some layout space on the occupant side at the same time. When welding the variable diameter pipe beam 8, by setting the load-bearing rod 7 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 adapt to 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 different positions of the variable diameter pipe beam 8 and support it.

[0044] Working principle: The pipe beam 8 moves along the feeding equipment toward the load-bearing rod 7. When the pipe beam 8 partially overlaps with the load-bearing rod 7, the first telescopic electric cylinder 6 works to make the U-shaped plate 12 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 driving motor 17 works to drive the threaded rod 4 to rotate. The rotating threaded rod 4 makes the mounting block 5 move to the right, thereby making the U-shaped plate 12 drag the pipe beam 8 to assist in feeding, until the right end of the pipe beam 8 abuts against the straight rod 19, and the first telescopic electric cylinder 6 contracts to make the U-shaped The plate 12 is separated from the tube beam 8. At this time, the U-shaped plate 12 returns to the left end of the load-bearing rod 7 under the action of the displacement mechanism. The first telescopic electric cylinder 6 extends to make the semicircular tube 13 support the left end of the load-bearing rod 7. Then the displacement mechanism works to make the U-shaped plate 12 move rightward until it abuts against the left end of the tube beam 8. At this time, the second telescopic electric cylinder 21 works to make the semicircular tube 13 move rightward and push the connecting sleeve 9, thereby making the push rod 10 act on the fixing plate 11, so that the fixing plate 11 fits the inner wall of the tube beam 8 and fixes the tube beam 8.

[0045] At this time, the feeding robot arm 3 and the welding robot arm 2 work, and the rotating motor 15 works to adjust the position of the pipe beam 8 and weld the parts on the surface of the pipe beam 8;

[0046] During the welding process of parts, the cooling device inputs coolant into the chamber in the fixing plate 11, and the coolant flows along the chamber. Due to the different diameters of the two connecting pipes 20, the pressure in the chamber increases, and the heat conducting block 26 is pushed 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 takes away the excess heat during welding, avoiding the deformation of the tube beam 8 caused by the accumulation of heat. When the fixing plate 11 supports the tube beam 8, the shape of the tube beam 8 is maintained, further avoiding the deformation of the tube beam 8.

[0047] After welding is completed, the U-shaped plate 12 retreats, and the spring 24 causes the fixing plate 11 to move toward the load-bearing rod 7, thereby losing the 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 description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
