Description

Technical Field

[0001] The utility model relates to a dotting tool for the turntable of an articulated vehicle, belonging to the technical field of dotting tools for articulated vehicles. Background Technique

[0002] The turntable of an articulated vehicle plays a crucial role in modern manufacturing. However, the technical defects and challenges in its production process not only affect production efficiency but also bring high costs. The traditional manual dotting process is particularly cumbersome and time-consuming due to the large size and heavy parts of the turntable.

[0003] First of all, the turntable of an articulated vehicle is usually large in size, resulting in a large number of parts to be processed and heavy weight during the assembly process. The traditional manual dotting process becomes particularly laborious in this case. Workers need to manually splice and align each part, which is not only time-consuming but also has a high safety hazard during the operation. When dealing with heavy parts, workers are prone to the risk of mechanical injuries, especially in the case of long-term operation and repetitive labor, the probability of safety accidents increases significantly. In addition, manual dotting is also likely to cause a decrease in the accuracy of the vehicle frame due to improper operation, thus affecting the final quality of the turntable.

[0004] Secondly, during the traditional manual dotting process, it is necessary to ensure the perpendicularity of the side plates on both sides of the turntable. In actual operation, due to the weight and volume of the parts, it is particularly difficult to maintain the perpendicularity of the side plates. Even if workers try their best to adjust during the dotting process, a small offset of the side plates will affect the final splicing effect, thus making it difficult to guarantee the assembly accuracy of the overall turntable. The limitations of this manual adjustment make the errors during the splicing process inevitable, ultimately affecting the performance and reliability of the turntable.

[0005] Furthermore, it is also very difficult to effectively guarantee the neatness of the docking joints during manual dotting. The docking of joints requires high precision and consistency, especially in the manufacturing process of large turntables. If the joints are not docked neatly, it will lead to structural instability, further affecting the use effect of the turntable. Due to the lack of precision docking tools and equipment in manual dotting, workers can only rely on experience and manual adjustment, and this method often makes it difficult to achieve precise docking of the joints. Summary of the Invention

[0006] Object of the Invention: To solve the above technical problems, the utility model provides a dotting tool for the turntable of an articulated vehicle. By setting a turntable side plate reference support and a turntable side plate installation support perpendicular to the bottom template assembly, and a side plate installation device for vertically pushing out the turntable side plate, the perpendicularity of the turntable side plate is guaranteed, and the assembly accuracy is improved.

[0007] Technical solution: An articulating boom turntable alignment tooling, comprising a controller and a bottom template assembly, a turntable side plate reference support, and a turntable side plate mounting support installed on a base. The turntable side plate reference support and the turntable side plate mounting support are respectively arranged on both sides of the bottom template assembly. The turntable side plate reference support and the turntable side plate mounting support are respectively perpendicular to the bottom template assembly and are respectively fixedly connected to the base. A side plate mounting device is arranged on the side of the turntable side plate mounting support close to the turntable. The side plate mounting device is signal-connected to the controller, and the controller controls the side plate mounting device to expand and contract along the direction perpendicular to the turntable side plate mounting support.

[0008] By providing a bottom template assembly, a turntable side plate reference support, and a turntable side plate mounting support corresponding to the turntable bottom plate and the two side plates of the turntable respectively, during alignment, first install the turntable bottom plate on the bottom template assembly, and then install a single turntable side plate on the turntable side plate reference support. Since the turntable side plate reference support is perpendicular to the bottom template assembly, the perpendicularity between the turntable side plate and the turntable bottom plate can be ensured. Then install the turntable intermediate partition, and then install the other turntable side plate on the turntable side plate mounting support. The side plate mounting device pushes the turntable side plate to abut and position against the intermediate partition. Since the side plate mounting device and the turntable side plate mounting support are perpendicular to each other, and the turntable side plate mounting support is perpendicular to the bottom template assembly, the perpendicularity between this turntable side plate and the turntable bottom plate can be guaranteed. Moreover, this tooling adopts a positioning mode of fixed on one side and movable on the other side on both the left and right sides, with a simple structure and accurate positioning.

[0009] Preferred option: In order to improve the stability during the welding of the turntable side plates, the turntable side plate reference supports and the turntable side plate mounting supports are arranged in pairs.

[0010] Preferred option: In order to accurately position and install the turntable straight side plates and the turntable bent side plates respectively, the turntable side plate reference support includes a first side plate reference support and a second side plate reference support. At least two groups of the first side plate reference support and the second side plate reference support are respectively provided. The first side plate reference support and the second side plate reference support are arranged front and back along the direction perpendicular to the turntable side plate.

[0011] Since the turntable bent side plates present an outward-expanded shape relative to the turntable straight side plates, it is necessary to arrange the first side plate reference support and the second side plate reference support front and back along the direction perpendicular to the turntable side plate to meet the corresponding arrangement of the first side plate reference support and the turntable straight side plates, and the corresponding arrangement of the second side plate reference support and the turntable bent side plates, so as to achieve the accurate positioning and installation of the turntable straight side plates and the turntable bent side plates.

[0012] Preferred option: To accurately position and install the flat side plate and the bent side plate of the turntable respectively, the turntable side plate mounting support includes a first side plate mounting support and a second side plate mounting support. At least two groups of the first side plate mounting support and the second side plate mounting support are respectively provided, and the first side plate mounting support and the second side plate mounting support are arranged front and back along the direction perpendicular to the turntable side plate.

[0013] Since the bent side plate of the turntable presents an outward-expanded shape relative to the flat side plate of the turntable, it is necessary to arrange the first side plate mounting support and the second side plate mounting support front and back along the direction perpendicular to the turntable side plate, so as to satisfy the corresponding setting of the first side plate mounting support and the flat side plate of the turntable, and the corresponding setting of the second side plate mounting support and the bent side plate of the turntable, and realize the accurate positioning and installation of the flat side plate and the bent side plate of the turntable.

The first straight part is arranged at the same height as the bottom straight plate, and the second straight part is lower than the first straight part.

[0016] Since the turntable side plate is composed of a flat side plate and a bent side plate of the turntable, the first straight part, the bent part and the second straight part are arranged to fit and install with it. The connection and assembly of the first straight part and the bottom straight plate improve the adaptability of this tooling to the bottom of the bent side plate of the turntable.

[0017] Preferred option: To ensure the perpendicularity of the turntable side plate, the side plate installation device includes a support plate and a hydraulic telescopic rod and a guide rod arranged in the same direction.
