Description

Technical Field

[0001] This invention relates to the technical field of vehicle engineering, and in particular to a vehicle steering axle welding device and welding process based on vehicle engineering. Background Technology

[0002] Vehicle engineering is a systems engineering discipline that designs, develops, manufactures, tests, and optimizes vehicles. When manufacturing vehicles, vehicle engineering typically uses welding equipment to weld the steering axle to increase the stability of the vehicle's steering process.

[0003] Existing welding equipment employs various methods to weld vehicle steering axle bodies. For example, a welding device and welding process for an industrial vehicle steering axle body is disclosed in CN104308385B. The welding device includes a stiffener and web positioning welding device, a kingpin seat axle plate positioning welding device, and a steering axle body positioning welding device. The welding process uses the aforementioned welding device to perform positioning welding of the steering axle body.

[0004] Existing welding equipment typically uses continuous welding to weld vehicle steering axle bodies. This welding method can cause localized overheating in the welding area of ​​the steering axle body, resulting in an overall temperature difference. This can easily lead to thermal deformation of the steering axle body, affecting welding accuracy. For example, in the aforementioned prior art, the equipment uses targeted welding to sequentially weld multiple components to the steering axle body. This welding method results in a longer welding time for each component to the steering axle body, causing the local welding area of ​​the steering axle body to heat up too quickly and create a temperature difference with other parts. Under the influence of this temperature difference, the steering axle body is prone to welding deformation, affecting welding accuracy. At the same time, the position of the steering axle body cannot be adjusted during welding, requiring continuous adjustment of the steering axle body position, resulting in low welding efficiency.

[0005] Therefore, it is urgent to design a vehicle steering axle welding device and welding process based on vehicle engineering to solve the above problems. Summary of the Invention

[0021] A vehicle steering axle welding process based on vehicle engineering, used in the aforementioned vehicle steering axle welding apparatus for vehicle engineering, includes the following steps:

[0022] S1. Place the main body of the steering axle to be welded into the welding box, and use the positioning components in the positioning unit to position the two ends of the steering axle main body.

[0023] S2. Start the welding gun to weld the main body of the steering axle. At the same time as welding, start the steering assembly to drive the main body of the steering axle to rotate, so as to achieve the rotating and circumferential welding of the main body of the steering axle.

[0024] S3. Simultaneously activate the displacement component to adjust the position of the welding gun, achieving multi-point welding;

[0026] This invention provides a welding device and welding process for vehicle steering axles based on vehicle engineering. It has the following beneficial effects:

[0027] 1. When welding the main body of the steering axle, this welding device can quickly fix both ends of the steering axle body by using hydraulic filling and expansion extrusion, which can effectively improve the welding stability of the steering axle body and avoid swaying or displacement during welding.

[0028] 2. When welding the main body of the steering axle, this welding device can adjust the angle of the steering axle body without changing its positioning during the welding process, thereby achieving rapid circumferential welding of the steering axle body. There is no need to adjust the positioning of the steering axle body during welding, resulting in higher welding efficiency.

[0029] 3. When welding the main body of the steering axle, this welding device can flexibly change the horizontal position and welding angle of the welding while welding, so that the main body of the steering axle can be welded comprehensively and in a multi-point interval. That is, after the initial point is welded, the next welding point at a long distance can be quickly welded. This not only makes the welding efficiency higher, but also prevents the local temperature on the main body of the steering axle from becoming too high, avoids welding thermal deformation, and effectively improves the welding accuracy.

[0030] 4. When welding the main body of the steering axle, this welding device can accelerate the airflow at the welding site by adsorption, thereby achieving rapid cooling of the welding site. At the same time, it can remove the waste generated during welding while adsorbing the air, thus preventing the accumulation of welding waste on the main body of the steering axle and affecting the welding quality.

[0031] In summary, this invention enables stable positioning and angle adjustment of the steering axle body, achieves multi-point circumferential welding, and allows for flexible changes in the position of welding points during welding. This not only improves welding efficiency through multi-point welding but also avoids mutual interference between closely spaced welding points, preventing localized overheating and thermal deformation of the steering axle body during welding. Furthermore, it enables segmented, intermittent welding with higher welding precision.

Detailed Implementation

[0050] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0051] Example 1: Refer to Figures 1-3 A vehicle steering axle welding device based on vehicle engineering includes a welding box 1, which is used to weld the steering axle body 11 in the field of vehicle engineering. The steering axle body 11 is the part to be welded on the vehicle steering axle. The welding device is used to achieve multi-point welding positioning of the steering axle body 11.

[0052] This welding apparatus also includes:

[0053] A welding platform 4 is set inside the welding box 1, and a servo motor 13 for driving is set at the lower part of the welding platform 4. The servo motor 13 plays a driving role and is used to assist the welding process of the steering axle body 11.

[0054] The positioning unit, set on the welding platform 4, is used to position the steering axle body 11 and adjust its steering position during welding. It enables rapid positioning of the steering axle body 11, improves the stability of its welding, and can adjust the angle of the steering axle body 11 without changing its positioning. This enables rapid circumferential welding of the steering axle body 11, without needing to adjust the positioning of the steering axle body 11 during welding, resulting in higher welding efficiency.

[0055] The welding unit equipped with welding gun 35 is set on welding platform 4 to realize multi-point and multi-position welding on the steering axle body 11. While welding, the horizontal position and welding angle of the welding can be flexibly changed, so that the steering axle body 11 can be comprehensively and intermittently welded, avoiding excessive local temperature of the steering axle body 11 during welding, avoiding welding thermal deformation, and effectively improving welding accuracy.

[0056] A shielding cover 2 is slidably installed on the welding box 1. The shielding cover 2 is used to shield the welding part and realize closed welding. The shielding cover 2 is provided with an observation window for observing the welding situation.

[0057] The welding box 1 is equipped with a control panel 3, which is used to control the opening and closing and operation status of the positioning unit and the welding unit, so as to realize the automated welding of the steering bridge body 11.

[0058] Example 2: Refer to Figures 1-3 The difference between this embodiment and embodiment one is that the positioning unit includes a positioning component and a steering component. The positioning component is used to achieve rapid positioning of the steering axle body 11, and the steering component operates under the drive of the servo motor 13 to achieve overall steering of the steering axle body 11.

[0059] The positioning assembly includes a side platform 6 and a side platform 8 set on the welding platform 4. Both the side platform 6 and the side platform 8 are rotatably mounted with linkage rollers 19, and both linkage rollers 19 are fixedly mounted with positioning collars 17 that cooperate with the end of the steering axle body 11.

[0060] Two linkage rollers 19 can rotate on side platform 6 and side platform 8 respectively, thereby driving the positioning rings 17 on the linkage rollers 19 to rotate. The two positioning rings 17 are used to fix the two ends of the steering axle body 11, so that the rotation of the linkage rollers 19 drives the positioning rings 17 to rotate, thereby driving the rotation of the steering axle body 11, and realizing the overall rotation of the steering axle body 11.

[0061] The welding platform 4 is equipped with a storage box 7 and a hydraulic push rod 9. A pusher plate 22 is slidably installed between the hydraulic push rod 9 and the storage box 7. The storage box 7 is filled with hydraulic oil. When the hydraulic push rod 9 is activated, it will drive the pusher plate 22 to move. When the pusher plate 22 moves forward, it will push the hydraulic oil out of the storage box 7. When the pusher plate 22 moves in the opposite direction, it will draw the external hydraulic oil back into the storage box 7 to complete the back suction.

[0062] In a further embodiment, a fastening mechanism is provided inside the positioning collar 17. The fastening mechanism includes an elastic wrapping ring 23 fixedly installed inside the positioning collar 17. A liquid guide pipe 10 for conducting hydraulic oil is fixedly connected to the storage tank 7, and a control valve is provided on the liquid guide pipe 10. An inlet ring 21 is fixedly connected to the end of the liquid guide pipe 10, and the inlet ring 21 is sleeved on the outside of the linkage roller 19. A liquid guide ring 24 is rotatably installed on the linkage roller 19, and the liquid guide ring 24 is connected to the inlet ring 21. Multiple filling pipes are fixedly connected between the liquid guide ring 24 and the elastic wrapping ring 23.

[0063] After the steering axle body 11 is installed, its end will be located in the elastic wrapping ring 23 inside the positioning collar 17. At this time, the hydraulic push rod 9 is activated to drive the push plate 22 to move forward and open the control valve in the guide pipe 10. At this time, the hydraulic oil in the storage tank 7 will enter the inlet ring 21 through the guide pipe 10.

[0064] Since the inlet ring 21 is connected to the guide ring 24, the hydraulic oil in the inlet ring 21 will enter the guide ring 24 and will be replenished to the elastic wrapping ring 23 through multiple filling pipes. At this time, the hydraulic oil in the elastic wrapping ring 23 will increase and expand, thereby wrapping and binding the steering axle body 11 of its inner ring for positioning. Then, the control valve is closed to cut off the backflow of hydraulic oil in the guide pipe 10, so that the hydraulic oil in the elastic wrapping ring 23 is always fully filled, thus achieving stable positioning of the steering axle body 11.

[0065] The liquid guiding ring 24 is rotatably connected to the liquid inlet ring 21, so that when the elastic wrapping ring 23 rotates with the positioning sleeve 17, the rotation of the positioning sleeve 17 will drive the liquid guiding ring 24 to rotate through multiple filling pipes. The rotation of the liquid guiding ring 24 will not affect the liquid inlet ring 21, that is, the liquid inlet ring 21 will not rotate, and will not affect the rotation of the steering axle body 11.

[0066] In a further embodiment, the steering assembly includes a drive roller 15 fixedly mounted on the drive end of the servo motor 13, a reduction roller 18 rotatably mounted on the drive roller 15 through the cooperation of the reducer 16, and the reduction roller 18 rotatably mounted in the welding box 1. The reduction roller 18 is provided with an electric self-locking ring, and a transmission belt 20 is sleeved between the electric self-locking ring and the linkage roller 19.

[0067] When the servo motor 13 starts, it drives the drive roller 15 to rotate. The rotation of the drive roller 15, after being decelerated by the reducer 16, drives the deceleration roller 18 to rotate. That is, the speed of the deceleration roller 18 is much less than the speed of the drive roller 15. When the deceleration roller 18 rotates, it will cooperate with the transmission belt 20 under the action of the electric self-locking ring to drive the linkage roller 19 to rotate. The rotation of the linkage roller 19 will drive the positioning collar 17 to rotate, thereby realizing the overall rotation of the steering axle body 11. The rotation of the steering axle body 11 will not affect its positioning state, thus enabling the circumferential welding of the steering axle body 11 and improving the welding range.

[0068] The electric self-locking ring is a commonly used structure for automatic locking in the prior art. When it is started, it can automatically lock onto the reduction roller 18. At this time, the rotation of the reduction roller 18 will drive the electric self-locking ring to rotate, which in turn drives the transmission belt 20 to transmit power. When the electric self-locking ring is not locked onto the reduction roller 18, the rotation of the reduction roller 18 will not drive the reduction roller 18 to rotate, so that the rotation of the drive roller 15 will not drive the rotation of the steering axle body 11, so as to facilitate welding in various states. The locking technology of the electric self-locking ring is existing technology and will not be elaborated on here.

[0069] Example 3: Refer to Figures 1-3 The difference between this embodiment and embodiment two is that the welding unit includes a displacement component, an angle adjustment component and an adsorption component. The displacement component is used to adjust the relative position of the welding gun 35 to achieve multi-position welding. The angle adjustment component is driven by the displacement component to adjust the welding angle of the welding gun 35, thereby achieving segmented and intermittent welding of the steering bridge body 11.

[0070] The displacement assembly includes a translational liquid storage box 25 fixedly installed on the welding platform 4, and a through conduction pipe 28 for guiding liquid is fixedly connected between the translational liquid storage box 25 and the storage tank 7, and a control valve is provided on the through conduction pipe 28. A translational support frame 26 is slidably installed inside the translational liquid storage box 25.

[0071] Open the control valve on the through-conduction pipe 28 to make the through-conduction pipe 28 connected. At this time, start the hydraulic push rod 9 to drive the push plate 22 to move forward and push out the hydraulic oil in the storage tank 7. At this time, the guide pipe 10 is closed, so that the hydraulic oil will only enter the through-conduction pipe 28. The hydraulic oil in the through-conduction pipe 28 will enter the translational storage box 25. At this time, the increase of hydraulic oil in the translational storage box 25 will push the translational support frame 26 to move forward.

[0072] When the push plate 22 moves in the reverse direction, the hydraulic oil in the translation reservoir 25 will be drawn back into the storage tank 7 through the through conduction pipe 28 under the action of negative pressure, which will drive the translation support frame 26 to move in the reverse direction. By repeating this process, the forward and reverse reciprocating movement of the translation support frame 26 can be achieved.

[0073] The translational storage box 25 has a translational groove that cooperates with the translational support frame 26. There are two mutually pressing sealing strips in the translational groove, and the translational support frame 26 is located between the two sealing strips. The two sealing strips do not affect the normal sliding of the translational support frame 26, and can seal the translational groove, thereby improving the overall sealing performance of the translational support frame 26.

[0074] In a further embodiment, the angle adjustment component includes an external support ring 12 fixedly installed in the translation support frame 26, a dust collection opening 5 is provided on the welding platform 4, and the external support ring 12 is located in the dust collection opening 5. An internal steering ring 29 is rotatably installed in the external support ring 12.

[0075] When the translation support frame 26 moves horizontally, it will drive the outer support ring 12 to move horizontally, thereby changing the relative position of the outer support ring 12 and the steering axle body 11, and realizing multi-position welding.

[0076] Two electric telescopic rods 34 are symmetrically arranged inside the built-in steering ring 29, and the ends of the two electric telescopic rods 34 are equipped with welding guns 35 for welding the steering axle body 11. After the position of the external support ring 12 is adjusted, the welding guns 35 can be started to quickly weld the steering axle body 11. At the same time, the rotation angle of the steering axle body 11 can be adjusted by cooperating with the steering components, thereby realizing the circumferential welding.

[0077] Furthermore, during welding, the electric telescopic rod 34 at the corresponding position can be activated to adjust the contact position between the welding gun 35 and the steering axle body 11 according to the height or depth of the protrusion at the welding position on the steering axle body 11, thereby achieving targeted welding at multiple positions and improving the welding effect.

[0078] In a further embodiment, the built-in steering ring 29 is provided with a rotation mechanism for adjusting the angle. The rotation mechanism includes a threaded limiting rod 27 fixedly installed on the inner wall of the ash discharge opening 5, a limiting frame 31 fixedly installed on the outside of the external support ring 12, and a threaded sleeve 33 that cooperates with the threaded limiting rod 27 is rotatably installed inside the limiting frame 31. A drive gear 32 is fixedly installed on the threaded sleeve 33 through an electric self-locking wheel, and a driven gear ring 30 that meshes with the drive gear 32 is fixedly installed on the built-in steering ring 29.

[0079] When the external support ring 12 moves horizontally, it will drive the limit frame 31 on it to move horizontally. When the limit frame 31 moves horizontally, it will drive the threaded sleeve 33 inside it to move horizontally. Since the threaded sleeve 33 is threadedly engaged with the threaded limit rod 27, the threaded sleeve 33 will rotate under the threaded engagement with the threaded limit rod 27 when it moves horizontally. That is, while the external support ring 12 moves horizontally, the threaded sleeve 33 moves synchronously and rotates.

[0080] When the threaded sleeve 33 rotates, it drives the drive gear 32 to rotate under the action of the electric self-locking wheel. When the drive gear 32 rotates, it drives the driven gear ring 30 that meshes with it to rotate. The rotation of the driven gear ring 30 drives the built-in steering ring 29 on it to rotate, which in turn drives the welding gun 35 inside the built-in steering ring 29 to rotate. This allows the relative welding points to be changed while moving, thereby avoiding welding in the same area for a long time. This avoids local overheating caused by excessive welding time in some areas of the steering axle body 11, and avoids thermal stress deformation. By using multi-point welding, the stability and smoothness of each area and point on the steering axle body 11 are achieved, avoiding large internal temperature differences during welding of the steering axle body 11, thus avoiding welding deformation and improving welding accuracy.

[0081] The electric self-locking wheel is used to control the locking relationship between the threaded sleeve 33 and the drive gear 32. Its basic principle is the same as that of the electric self-locking ring mentioned above, and will not be elaborated on here. When the electric self-locking ring is activated, the threaded sleeve 33 and the drive gear 32 are locked together. At this time, the movement of the outer support ring 12 will drive the drive gear 32 to rotate, which in turn drives the inner steering ring 29 to rotate, realizing the alternating welding of multiple welding points. When the threaded sleeve 33 is not locked with the drive gear 32, the movement of the outer support ring 12 will not cause the inner steering ring 29 to rotate, thereby realizing the horizontal linear welding on the steering axle body 11.

[0082] In a further embodiment, the adsorption assembly includes a wind box 14 fixedly installed at the lower part of the welding platform 4, and the wind box 14 is rotatably connected to the drive roller 15. A wind impeller 38 is fixedly installed on the drive roller 15, and the wind impeller 38 is located inside the wind box 14. A filter screen 39 for blocking welding waste is fixedly installed inside the wind box 14.

[0083] While welding, the servo motor 13 is started to drive the drive roller 15 to rotate, and the rotation of the drive roller 15 drives the impeller 38 to rotate.

[0084] A limiting rotating ring is rotatably installed on the built-in steering ring 29, and the limiting rotating ring is connected to the built-in steering ring 29. An adsorption telescopic tube 37 for adsorbing air and welding waste is fixedly connected between the limiting rotating ring and the air box 14. Multiple adsorption holes 36 for air intake are opened on the built-in steering ring 29.

[0085] When the impeller 38 rotates, it generates a negative pressure suction force through the suction telescopic tube 37. This suction force draws welding waste generated during welding into the built-in steering ring 29 through multiple suction holes 36. The welding waste is then drawn into the air box 14 through the limiting rotating ring and the suction telescopic tube 37, thus completing the removal of welding waste. At the same time, the air near the welding gun 35 is also drawn out, thereby accelerating the airflow speed at the welding part of the steering axle body 11. This helps to cool the welding part, accelerates the cooling rate, further prevents overheating, and improves the welding effect.

[0086] When implemented, this invention can achieve multi-position circumferential welding of the steering axle body 11 according to the specific welding requirements of the steering axle body 11, as well as linear welding and multi-point, intermittent spiral welding on the steering axle body 11, resulting in stronger welding functionality and better welding effect.

[0087] This invention also provides a vehicle steering axle welding process based on vehicle engineering, using the aforementioned vehicle steering axle welding device for vehicle engineering, comprising the following steps:

[0088] S1. Place the steering axle body 11 to be welded into the welding box 1, and use the positioning components in the positioning unit to position the steering axle body 11 at both ends.

[0089] S2. Start the welding gun 35 to weld the steering axle body 11. At the same time as welding, start the steering assembly to drive the steering axle body 11 to rotate, so as to achieve the rotational and circumferential welding of the steering axle body 11.

[0090] S3. Simultaneously with welding, the displacement component is activated to adjust the position of the welding gun 35, achieving multi-point welding;

[0091] S4. While performing multi-point welding, the welding gun 35 will rotate under the drive of the angle adjustment component, thereby changing the welding angle of the welding gun 35 to achieve segmented and intermittent welding, avoiding localized heating and deformation of the steering bridge body 11.

[0092] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
