Description

Technical Field

[0001] This utility model belongs to the technical field of welding equipment, and specifically relates to an automotive axle welding device. Background Technology

[0002] A car axle is connected to the chassis or monocoque body via the suspension system. Wheels are mounted at both ends of the axle. The axle's function is to bear the load of the car and maintain its normal driving on the road. The axle can be a solid piece, like a giant barbell, with both ends supporting the body through the suspension system. Therefore, solid axles are usually used with non-independent suspensions. Axles can also be split, like two umbrellas inserted on both sides of the body, each supporting the body through its own suspension system. Therefore, split axles are used with independent suspensions. During the production of car axles, welding equipment is required to weld them together.

[0003] However, existing welding workbenches are not convenient for flexibly adjusting the width between the support platforms of the front and rear axles. This results in poor adaptability for welding axles with different spans. Furthermore, since the span of axle welding is relatively large, the adjustment process involves moving and adjusting the positions of the support platforms at both ends sequentially during the welding process, making the adjustment steps cumbersome and accurate positioning difficult. Therefore, an automotive axle welding device is needed to solve the problems existing in the prior art. Utility Model Content

[0004] The purpose of this invention is to provide an automotive axle welding device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an automobile axle welding device, including a middle axle support platform, a rear axle support platform on one side of the middle axle support platform, and a front axle support platform on the other side of the middle axle support platform. A synchronous adjustment mechanism is provided inside the middle axle support platform. The synchronous adjustment mechanism includes a first toothed plate, a second toothed plate, a first adjustment wheel, a second adjustment wheel, and a synchronous belt. The first toothed plate is fixed to one end of the front axle support platform, and the second toothed plate is fixed to one end of the rear axle support platform. The first adjustment wheel and the second adjustment wheel are rotatably connected inside the middle axle support platform, and the synchronous belt is disposed between the first adjustment wheel and the second adjustment wheel.

[0006] It should be noted in the scheme that both the first adjusting wheel and the second adjusting wheel include a fixed-point turntable, an upper meshing tooth, and a lower meshing tooth. The fixed-point turntable is disposed in the inner cavity of the middle bridge lifting platform. The upper meshing tooth is disposed on the upper part of the side surface of the fixed-point turntable, and the lower meshing tooth is disposed on the lower part of the side surface of the fixed-point turntable.

[0007] It is further worth noting that the synchronous belt is engaged with the lower meshing teeth of the fixed-point turntable, the first toothed plate is engaged with the upper meshing teeth on the first adjusting wheel, and the second toothed plate is engaged with the upper meshing teeth on the second adjusting wheel.

[0008] Furthermore, it should be noted that a rotating shaft is fixed at the center of both the upper and lower end faces of the fixed-point turntable, and the rotating shaft is rotatably connected to the inner wall of the middle bridge lifting platform.

[0009] In a preferred embodiment, adjustable guide rods are provided between the middle axle lifting platform and the front axle lifting platform, and between the rear axle lifting platform and the middle axle lifting platform, and the adjustable guide rods are slidably connected to the middle axle lifting platform.

[0010] In a preferred embodiment, both the front axle lifting platform and the rear axle lifting platform are fixed with lifting cylinders. The output end of the lifting cylinder is fixed with a lifting pressure plate. A horizontal sliding frame is fixed on one side of the lifting pressure plate. An adjustment port is opened on the upper end face of the horizontal sliding frame. A welding gun is slidably connected in the adjustment port of the horizontal sliding frame.

[0011] Compared with the prior art, the automobile axle welding device provided by this utility model has at least the following beneficial effects:

[0012] With the addition of a front axle support platform, a rear axle support platform, and lifting pressure plates, the two lifting pressure plates can restrict the docking and assembly of the two ends of the middle axle housing with the front axle assembly and the rear axle assembly, thereby reducing the displacement of the middle axle housing during welding and affecting the welding quality.

[0013] With the set synchronous adjustment mechanism, the rear axle lifting platform and the front axle lifting platform can move closer or further away from the two ends of the middle axle lifting platform in a synchronous control manner. In conjunction with the adjustment function of the front axle lifting platform and the rear axle lifting platform, it can adapt to welding operations on middle axle shells of different lengths.

[0019] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. The components of the embodiments of this utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0020] Please see Figure 1-4 This utility model provides an automobile axle welding device, including a middle axle support platform 1, a rear axle support platform 3 on one side of the middle axle support platform 1, and a front axle support platform 2 on the other side of the middle axle support platform 1. A synchronous adjustment mechanism is provided inside the middle axle support platform 1. The synchronous adjustment mechanism includes a first toothed plate 5, a second toothed plate 6, a first adjustment wheel 7, a second adjustment wheel 8, and a synchronous belt 9. The first toothed plate 5 is fixed to one end of the front axle support platform 2, the second toothed plate 6 is fixed to one end of the rear axle support platform 3, the first adjustment wheel 7 and the second adjustment wheel 8 are both rotatably connected inside the middle axle support platform 1, and the synchronous belt 9 is located between the first adjustment wheel 7 and the second adjustment wheel 8.

[0021] Further as Figure 1 , Figure 2 and Figure 3 As shown, it is worth noting that both the first adjusting wheel 7 and the second adjusting wheel 8 include a fixed-point turntable 15, an upper meshing tooth 16, and a lower meshing tooth 17. The fixed-point turntable 15 is located in the inner cavity of the middle bridge lifting platform 1. The upper meshing tooth 16 is located on the upper part of the side surface of the fixed-point turntable 15, and the lower meshing tooth 17 is located on the lower part of the side surface of the fixed-point turntable 15.

[0022] Further as Figure 3 As shown, it is worth noting that the synchronous belt 9 is engaged with the lower meshing tooth 17 of the fixed-point turntable 15, the first tooth plate 5 is engaged with the upper meshing tooth 16 on the first adjusting wheel 7, and the second tooth plate 6 is engaged with the upper meshing tooth 16 on the second adjusting wheel 8.

[0023] The solution has the following working process: Before use, the front axle assembly and the rear axle assembly of the car are placed on the front axle support platform 2 and the rear axle support platform 3, respectively, while the middle axle housing is placed on the middle axle support platform 1 and its two ends overlap the front axle assembly and the rear axle assembly. Then, the lifting cylinder 12 is activated, which drives the lifting pressure plate 10 to descend and press and limit the middle axle housing. In this way, the two lifting pressure plates 10 can restrict the docking and combination of the two ends of the middle axle housing with the front axle assembly and the rear axle assembly, thereby reducing the displacement of the middle axle housing during welding and affecting the welding quality.

[0024] As can be seen from the above working process, the two lifting pressure plates 10 can restrict the docking and assembly of the two ends of the middle bridge housing with the front axle assembly and the rear axle assembly, thereby reducing the displacement of the middle bridge housing during welding and affecting the welding quality.

[0025] Further as Figure 1 , Figure 2 and Figure 4 As shown, it is worth noting that a rotating shaft 18 is fixed at the center of both the upper and lower end faces of the fixed-point turntable 15, and the rotating shaft 18 is rotatably connected to the inner wall of the middle bridge lifting platform 1.

[0026] Further as Figure 4 As shown, it is worth noting that adjustable guide rods 4 are provided between the middle axle lifting platform 1 and the front axle lifting platform 2, and between the rear axle lifting platform 3 and the middle axle lifting platform 1. The adjustable guide rods 4 are slidably connected to the middle axle lifting platform 1. Before placing the welding object, the rear axle lifting platform 3 at one end of the middle axle lifting platform 1 is moved, which drives the second toothed plate 6 to control the rotation of the second adjustable wheel 8. Since the synchronous belt 9 is engaged between the first adjustable wheel 7 and the second adjustable wheel 8, the first adjustable wheel 7 rotates accordingly. The rotation of the first adjustable wheel 7 will drive the first toothed plate 5 to extend outward. In this way, the rear axle lifting platform 3 and the front axle lifting platform 2 can be synchronously controlled to move closer or further away from the two ends of the middle axle lifting platform 1. With the adjustable function of the front axle lifting platform 2 and the rear axle lifting platform 3, welding operations can be carried out on middle axle shells of different lengths.

[0027] Further as Figure 1 As shown, it is worth noting that both the front axle lifting platform 2 and the rear axle lifting platform 3 are fixed with lifting cylinders 12. The output end of the lifting cylinder 12 is fixed with a lifting pressure plate 10. A horizontal sliding frame 11 is fixed on one side of the lifting pressure plate 10. An adjustment port 13 is opened on the upper end face of the horizontal sliding frame 11. A welding gun 14 is slidably connected in the adjustment port 13 of the horizontal sliding frame 11.

[0028] In summary: the two lifting pressure plates 10 can restrict the docking and assembly of the two ends of the middle axle housing with the front axle assembly and the rear axle assembly, thereby reducing the displacement of the middle axle housing during welding and affecting the welding quality; the rear axle lifting platform 3 and the front axle lifting platform 2 can be controlled to move closer or further away from the two ends of the middle axle lifting platform 1 simultaneously, and with the distance adjustment function of the front axle lifting platform 2 and the rear axle lifting platform 3, they can adapt to welding operations for middle axle housings of different lengths.
