Description

Technical Field

[0001] This application relates to the technical field of welding process equipment for railway products, specifically to a tooling assembly for welding box bodies. Background Technology

[0002] In the field of rail transit vehicles, in order to increase the usable space for passengers, various functional equipment is installed in the undercarriage equipment compartment as much as possible. As the speed of rail transit vehicles increases, the requirements for the safety and reliability of the undercarriage equipment installation become increasingly stringent. The installation structure between the undercarriage equipment and the car body of rail transit vehicles mainly adopts two connection structure types: "suspension" and "lifting". The main load-bearing components of the car body and the undercarriage equipment are welded structural components.

[0003] In existing technologies, the assembly and welding process involves manual measurement and assembly of each component, requiring manual measurement, assembly, and riveting of each component.

[0004] However, traditional manual measurement, grinding, and welding of parts is slow, and the dimensional tolerances of manually measured, ground, and welded parts are unstable when mass-producing products, resulting in a decline in the average quality of the products. Utility Model Content

[0005] To address the problems mentioned in the background art and improve the assembly efficiency and quality of the enclosure, this application provides a tooling assembly for enclosure welding. This tooling assembly includes lifting lug assemblies disposed on both sides of the enclosure, and auxiliary lifting lug assemblies and positioning assemblies disposed at the bottom of the enclosure. The lifting lug assemblies and auxiliary lifting lug assemblies form a frame structure for placing the enclosure. The positioning assembly includes at least two positioning rods extending in a first direction for pre-positioning the enclosure. The lifting lug assemblies include a first plate, and the auxiliary lifting lug assemblies include a second plate. Holes are formed on the surfaces of the first and second plates, and partial structures on each surface of the enclosure connect to these holes to fix the enclosure's position.

[0006] In this application, the container is a waste bin for high-speed trains. The upper surface of the waste bin is evenly provided with four connecting plates, which are used to connect the first plates on the lifting lug assembly. The bottom of the waste bin is also provided with a bent plate corresponding to the second plate. Before welding, the various components on the waste bin are aligned with the holes opened on the first and second plates. At the same time, the positioning rod provided below can also be used to position the installation position of the waste bin through the positioning groove at the bottom of the waste bin. This avoids the need for manual measurement and fitting before welding and improves the efficiency of waste bin installation.

[0007] According to one embodiment provided in this application, the lifting lug assembly further includes a first frame and at least two support rods inclined on the same side. One end of the support rod is connected to the edge of the first frame, and the other end of the support rod is connected to a first crossbar. The lifting lug assemblies on both sides of the box share at least two first crossbars.

[0008] With this configuration, the lifting lug assembly is shaped like a gantry frame. Two fixed ribs are provided at the corners of the first frame. Two support rods are fixedly connected to the same side surface of the first frame. The two sides of the first frame share two first horizontal bars that are perpendicular to the surface of the first frame to form a lifting shape. The purpose of this is to improve the supporting force of the first frame and prevent the first frame from being damaged during the installation and welding of the waste bin to the first frame.

[0009] According to one embodiment provided in this application, at least three third crossbars are provided below the first crossbar, and both ends of the third crossbars are fixedly connected to the first frame.

[0010] According to one embodiment provided in this application, a reinforcing beam is installed on the middle third crossbar, and the two ends of the reinforcing beam are fixedly connected to the other two third crossbars to improve the tightness of the tooling assembly.

[0011] With this configuration, the bottom of the first frame is fixedly connected to the third crossbar. The two sides of the first frame share three third crossbars. The middle section of each third crossbar also features multiple symmetrical reinforcing beams perpendicular to the third crossbars to improve the stability of the tooling assembly and further enhance its overall load-bearing capacity. Furthermore, since the waste bin needs to be disassembled, reinforcing the bottom of the first frame also improves the overall stability of the assembly.

[0012] According to one embodiment provided in this application, a first plate is disposed at the end of the first frame away from the third crossbar, and the first plate is in the shape of a "C".

[0013] With this configuration, the first plate is made of "C" shaped steel and is framed on the upper part of the first frame. The part where the first frame connects to the first plate has a through hole. During the welding process of the waste bin, the through hole at the upper part of the first frame reduces the force on the side of the internal rivets, improves the reliability of the waste bin installation, and reduces the welding deformation of the lifting lug assembly.

[0014] According to one embodiment of this application, the positioning component further includes multiple second crossbars, with the two ends of the second crossbars connected to the first crossbars, and the positioning rods are evenly distributed on the second crossbars.

[0015] With this setup, four positioning rods are symmetrically distributed on the second crossbar. These rods are mainly aligned with the four holes at the bottom of the waste bin. This not only speeds up the positioning process and improves welding efficiency, but also secures the waste bin to prevent it from shifting during the welding process.

[0016] According to one embodiment provided in this application, the auxiliary lug assembly further includes a first base disposed in the same direction as the first crossbar, and a groove extending through the length of the first base is provided on the first base, and a second plate is disposed in the groove.

[0017] According to one embodiment of this application, a fixing plate is connected to the bottom of the second plate, and the other end of the fixing plate is connected to the surface of the first base.

[0018] With this configuration, the tooling assembly has 10 second plates, each with two through holes for connection. These through holes are located above the grooves to facilitate processing by workers. Due to the location of the through holes, the center of the second plate is not on the centerline of the first base. Therefore, a fixing plate is provided at the bottom of the second plate to strengthen the connection between the second plate and the first base.

[0019] According to one embodiment of this application, the first substrate has symmetrical auxiliary substrates at its ends, and fixing components are provided on the auxiliary substrates.

[0020] According to one embodiment of this application, the fixing component includes a grooved plate and a support plate, wherein the support plate is disposed perpendicular to the grooved plate and fixedly connected to the auxiliary substrate.

[0021] With this configuration, the fixing components are located at both ends of the first base, and the grooved plates on the fixing components are used for positioning and fixing other types of waste bins. The purpose of setting the fixing components is to enable the tooling components to meet the needs of various types of waste bins and reduce the cost of producing additional tooling components.

[0022] This application provides a tooling assembly for welding a container, wherein the container is a waste bin. The upper surface of the waste bin is evenly provided with four connecting plates, which are used to connect the first plates on the lifting lug assembly. The bottom of the waste bin is also provided with a bent plate corresponding to the second plate. Before welding, the various components on the waste bin are aligned with the holes opened on the first and second plates. At the same time, the positioning rod provided below can also be used to position the installation position of the waste bin through the positioning groove at the bottom of the waste bin, avoiding the need for manual measurement and fitting before welding, and improving the efficiency of waste bin installation.

[0034] In the field of rail transit vehicles, in order to increase the usable space for passengers, various functional equipment is installed in the undercarriage equipment compartment as much as possible. As the speed of rail transit vehicles increases, the requirements for the safety and reliability of the undercarriage equipment installation become increasingly stringent. The installation structure between the undercarriage equipment and the car body of rail transit vehicles mainly adopts two connection structure types: "suspension" and "lifting".
