[0021] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0022] As Figure 1 and Figure 2 shown, a welded structure of a slide carriage assembly includes a slide carriage plate 1, welded slide carriage side plates 2, a perforated positioning shaft 3, triangular ribs 4, and a hanging link plate 5. The slide carriage plate 1 is the base plate of the entire structure. The welded slide carriage side plates 2 are composed of two parts and are arranged on the slide carriage plate 1. The perforated positioning shaft 3 is located in the middle of the slide carriage plate 1 and passes through the welded slide carriage side plates 2. Two triangular ribs 4 are respectively arranged on both sides of the middle of the slide carriage plate 1 and are connected to the welded slide carriage side plates 2. The hanging link plate 5 is arranged at the bottom of the slide carriage plate 1 and is used to connect other components.

[0023] The welded structure of the slide carriage assembly provides basic support through the slide carriage plate 1. The main components of the slide carriage plate 1 are designed as an integrated structure. By optimizing the shape and position of the welding joints, the number and size of the welding joints are reduced, and the welding stress and deformation are reduced. This design makes the slide carriage structure more compact and stable, and improves the overall strength. The welded slide carriage side plates 2 provide guarantee for lateral stability. Perforated positioning shafts 3 for welding are added at key parts of the slide carriage plate 1. These perforated positioning shafts 3 for welding are used as positioning references during the welding process. The various components of the slide carriage are pre-positioned through two perforated shafts 3, and rapid and accurate welding alignment can be achieved without additional tooling. According to the characteristics of the slide carriage assembly structure and the requirements of the welding process, a reasonable welding sequence is formulated. First, welding with low stress and low deformation is carried out, and then welding with high stress and high deformation is carried out. At the same time, appropriate welding process parameters, such as welding current, welding speed, etc., are selected to ensure welding quality and efficiency. The design of the perforated positioning shaft 3 ensures the precise alignment of the position of the welded slide carriage side plates 2 and increases the overall structural strength. The triangular ribs 4 further enhance the connection strength between the welded slide carriage side plates 2 and the slide carriage plate 1, preventing lateral displacement or deformation. The hanging link plate 5 is located at the bottom of the slide carriage plate 1 and can be used to hang or connect other components, making the entire structure more stable and reliable.

[0024] This welding structure provides stable support and positioning, ensuring the stability and reliability of the carriage assembly under various stress conditions. The use of the perforated positioning shaft 3 effectively reduces welding errors and improves manufacturing accuracy. The addition of the triangular ribs 4 increases the shear strength of the welding structure, enhances the connection strength between the side plate and the bottom plate, and extends the service life of the structure. The design of the hanging chain plate 5 increases the versatility of the structure, making it more widely applicable in different application scenarios. The precise configuration of the triangular ribs and the hanging chain plate enables self-positioning welding without special tooling. This design reduces the cost of tooling design and manufacturing, simplifies the production process, and significantly reduces the manufacturing cost. Through the design of the perforated positioning shaft, precise positioning between the carriage side plate weldment and the carriage plate is ensured, avoiding welding position deviation problems caused by tooling wear and error accumulation. During the welding process, each component can maintain a stable relative position, thus ensuring high-precision welding and reliable connection, improving the accuracy and efficiency of welding positioning, reducing errors and deviations during the welding process, reducing welding deformation and welding stress, improving the overall accuracy and stability of the carriage, and reducing the time for installing and disassembling the tooling. The self-positioning characteristics between the components of the carriage assembly greatly shorten the production preparation time, improve production efficiency, and avoid production pauses caused by tooling adjustment in traditional processes. Through the design of the triangular ribs, the connection strength between the carriage side plate weldment and the carriage plate is enhanced, and the stability of the overall structure is improved. The reasonable layout of the hanging chain plate further enhances the load-bearing capacity of the carriage assembly, ensuring the service life and safety of the product.

[0025] In this embodiment, different welding processes or materials can be used for the carriage side plate weldment 2, such as laser welding or high-strength steel, to adapt to different manufacturing requirements and usage environments. The size and material of the perforated positioning shaft 3 can be adjusted according to needs to improve the load-bearing capacity or adapt to different load conditions. The shape and position of the triangular ribs 4 can be optimized according to specific application requirements to improve the connection strength or reduce the material usage. The design of the hanging chain plate 5 can also be adjusted according to actual needs, such as adding more mounting holes or changing its size, to adapt to different connection requirements.

[0026] The carriage side plate weldment 2 includes a left carriage side plate weldment 21 and a right carriage side plate weldment 22. The left carriage side plate weldment 21 and the right carriage side plate weldment 22 are respectively fixedly connected to the carriage plate 1 through welding joints. The welding joints adopt the form of fillet welds. The left carriage side plate weldment 21 and the right carriage side plate weldment 22 are symmetrical and parallel to each other.

[0027] The left carriage side plate weldment 21 and the right carriage side plate weldment 22 are connected to the carriage plate 1 by fillet welds. The design of the fillet welds not only improves the strength of the welded joint but also reduces stress concentration, thereby reducing the risk of fracture at the welded joints. The symmetrical design of the two side plate weldments ensures the balance and symmetry of the entire carriage, guaranteeing the overall stability of the structure.

[0028] The connection method using fillet welds effectively improves the fatigue strength and impact resistance of the welded joint, extending the service life of the structure. The symmetrical design of the left carriage side plate weldment 21 and the right carriage side plate weldment 22 reduces the offset and distortion of the structure, ensuring the stability and reliability of the carriage during use.

[0029] In different application scenarios, different metal alloys can be selected for the material of the carriage side plate weldment 2 to improve corrosion resistance or reduce weight. The shape and size of the welded joint can also be optimized according to specific force requirements, such as using a larger radius fillet or adding additional reinforcement to improve the connection strength. In addition, the relative positions of the left carriage side plate weldment 21 and the right carriage side plate weldment 22 can be finely adjusted to adapt to different installation requirements or special structural requirements.

[0030] The perforated positioning shaft 3 passes through the perforations on the carriage plate 1, the left carriage side plate weldment 21, and the right carriage side plate weldment 22, and the perforated positioning shaft 3 is perpendicular to the left carriage side plate weldment 21 and the right carriage side plate weldment 22. Through the design of the perforated positioning shaft 3, it ensures the precise positioning of the left and right carriage side plate weldments 21 and 22 with respect to the carriage plate 1 during the welding process, thereby achieving high-precision welding.

[0031] The perforated positioning shaft 3 provides a self-positioning structure that passes through the positioning holes of the carriage plate 1 and the two side plate weldments, enabling the left carriage side plate weldment 21 and the right carriage side plate weldment 22 to achieve precise alignment without additional tooling. Through its own positioning function, the perforated positioning shaft 3 ensures the accurate alignment of the carriage side plates and the carriage plate during the welding process, reducing the accumulation of errors during welding and preventing the offset of the welding position. This self-positioning design reduces the dependence on special tooling, lowers production costs, and reduces error problems caused by tooling wear.

[0032] The use of the perforated positioning shaft 3 reduces errors and deviations during the welding process, ensuring precise positioning between the carriage side plates and the carriage plate, thereby improving the welding precision and connection reliability. The self-positioning structure not only reduces the tooling design and manufacturing costs but also simplifies the production process, improving the accuracy and efficiency of welding positioning. By reducing welding deformation and welding stress during the welding process, it further improves the overall precision and stability of the carriage assembly, while reducing the time required for installing and disassembling the tooling, thus significantly enhancing production efficiency.

[0033] Under different manufacturing conditions, the material and dimensions of the perforation positioning shaft 3 can be adjusted as needed to adapt to different load requirements or machining accuracy requirements. In addition, different surface treatment technologies, such as hardening or plating, can be considered to improve the wear resistance and service life of the perforation positioning shaft. For specific applications, the number and layout of the perforation positioning shafts 3 can also be optimized to further improve the positioning accuracy or meet special welding requirements.

[0034] The two triangular ribs 4 are fixedly connected to both sides of the middle part of the carriage plate 1. One of the triangular ribs 4 is fixedly connected to the welded joint 21 of the left carriage side plate, and the other triangular rib 4 is fixedly connected to the welded joint 22 of the right carriage side plate. The connection between the triangular rib 4 and the carriage plate 1 and the carriage side plate weld is achieved by welding to increase the rigidity and stability of the overall structure.

[0035] The design of the triangular rib 4 makes the connection between the welded joint 21 of the carriage side plate and the welded joint 22 of the right carriage side plate and the carriage plate 1 more stable. By arranging the triangular ribs 4 on both sides of the middle part of the carriage plate 1, the load can be effectively dispersed, the connection strength between the carriage side plate and the carriage plate can be improved, and the offset or deformation of the side plate under the action of force can be prevented. This layout ensures the overall stability and durability of the welded structure when bearing external forces.

[0036] The addition of the triangular rib 4 significantly improves the shear strength and overall rigidity of the carriage assembly, enhances the connection between the side plate and the carriage plate, and prevents the displacement of the side plate or the cracking of the welded joint. At the same time, this structural design also effectively reduces the deformation of the carriage assembly during use and extends the service life of the product. In addition, the reasonable layout of the triangular rib 4 reduces the welding stress concentration and further improves the welding quality.

[0037] According to different usage requirements, the shape and dimensions of the triangular rib 4 can be adjusted, such as increasing the height of the triangular rib or changing its thickness, to enhance the connection strength between the carriage side plate and the carriage plate. Triangular ribs made of different materials, such as high-strength alloys or composite materials, can also be selected to further improve the strength and durability of the overall structure. In addition, the welding method and position of the triangular rib can be optimized according to specific force analysis to adapt to different load conditions and application scenarios.

[0038] The hanging chain plate 5 is connected to the bottom of the carriage plate 1. The hanging chain plate 5 is fixedly connected to the bottom of the carriage plate 1 by means of welding or bolt connection to ensure sufficient support and fixation when carrying heavy objects.

[0039] The hanging link plate 5 is arranged at the bottom of the carriage plate 1. Through reasonable layout and connection methods, it provides a support structure for hanging or connecting other components. The design of the hanging link plate 5 not only enhances the load-bearing capacity of the carriage assembly but also ensures the stability and safety of the overall structure through its connection with the carriage plate 1.

[0040] The reasonable layout and connection methods of the hanging link plate 5 improve the load-bearing capacity of the carriage assembly, ensuring that when carrying heavy objects or other connecting components, the carriage assembly can remain stable without displacement or detachment, extending the service life of the product and improving the usage safety. In addition, through welding or bolt connection methods, the connection between the hanging link plate 5 and the carriage plate 1 is firm and reliable, capable of withstanding large loads without deformation.

[0041] The size and thickness of the hanging link plate 5 can be adjusted according to actual load-bearing requirements, such as increasing the thickness of the hanging link plate or using high-strength materials to improve its load-bearing capacity. The connection method of the hanging link plate 5 can also adopt other mechanical connection methods, such as snap connection or quick-disassembly connection, for easy quick installation and disassembly in different application scenarios. In addition, according to different application requirements, more mounting holes can be added or their positions can be adjusted on the hanging link plate to meet various connection requirements.

[0042] A plurality of mounting holes are provided on the hanging link plate 5, which are used for installing and connecting other components and can provide flexible connection methods.

[0043] The multiple mounting holes on the hanging link plate 5 enable this component to be easily connected to other structures or components, providing a variety of possible connection methods and increasing the adaptability and versatility of the carriage assembly. The positions and quantities of the mounting holes are optimized to adapt to different installation requirements and usage scenarios.

[0044] By providing a plurality of mounting holes on the hanging link plate 5, the carriage assembly can adapt to various different installation and connection requirements, improving its applicability and flexibility in different scenarios. The design of multiple mounting holes enables the hanging link plate 5 to cooperate with various different types of connectors or suspension devices, increasing the versatility of the carriage assembly, while also simplifying the installation process and improving the production and assembly efficiency.
