Description

Technical Field

[0001] This utility model relates to the field of auxiliary tooling technology for assembling bogie components of rail vehicles, and in particular to a bogie mounting device for rail passenger cars. Background Technology

[0002] like Figure 1 As shown, the bogie bracket of the rail passenger car is composed of frame side beam 1-1, bracket 1-2, bracket 1-3, bracket 1-4, bracket 1-5, bracket 1-6, bracket 1-7, and bracket 1-8. Each bracket has a different shape and is located in a different position on the frame side beam, which brings difficulties to the assembly process.

[0003] The current assembly method involves operators drawing multiple auxiliary lines on the bogie side beams according to the design drawings before assembly. The mounting brackets are then assembled one by one according to these auxiliary lines. After assembly, each bracket is re-measured to confirm that the dimensions in each direction meet the drawing requirements. Because the assembly process demands zero tolerance for error, manual assembly in batch production often leads to errors in the operator's measuring and marking, resulting in inconsistent final assembly accuracy. This leads to poor consistency, an extremely high rework rate, increased production costs, increased operator workload, low production efficiency, and severely restricts production. Utility Model Content

[0004] The purpose of this utility model is to overcome the defects of the existing technology and provide a bogie seat assembly device for railway passenger cars. This device solves the technical problems of the existing technology, which uses manual assembly to assemble bogie seats, resulting in unreliable assembly accuracy, extremely high rework rate, and low production efficiency.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] The present invention discloses a bogie mounting device for railway passenger cars, comprising:

[0007] The crossbeam has positioning pins fixed at both ends of its lower surface, which mate with the round holes on the upper end face of the side beam of the frame, to position the crossbeam on the frame. The crossbeam has multiple downwardly extending positioning rods fixed on one side to provide a positioning surface for the card holder, so that the card holder abuts against the positioning surface to determine its position on the frame.

[0008] Furthermore, the positioning rods comprise four.

[0009] Furthermore, one end of the positioning rod is fixedly connected to the crossbeam, while the other end is a free end.

[0010] Furthermore, the positioning rod has a plate-like structure, and its side surface forms the positioning surface of the card seat.

[0011] The bogie mounting device for rail passenger cars provided by this utility model has the following advantages in the above technical solution:

[0012] This device, firstly, uses the positioning pins on the crossbeam to engage with the round holes 1-9 on the upper end face of the side beam of the frame to position the crossbeam 2-1 on the frame. Secondly, multiple positioning rods are fixedly connected to the corresponding card slot positions on one side of the crossbeam to provide a positioning surface for the card slot to abut. The use of this device replaces the manual marking and assembly of the card slots, ensuring the stability and reliability of the card slots during assembly, ensuring the assembly accuracy each time, zero rework rate, not only ensuring consistency during mass production, but also improving production efficiency by 5 to 10 times, reducing the labor intensity of operators, and saving labor and production costs.

The top of the first positioning rod 2-2 is integrally formed with a diagonal rib on the side of the card seat 1-2, and the end of the diagonal rib is fixedly connected to the crossbeam 2-1.

[0030] A protrusion is formed on one side of the second positioning rod 2-3. The side surface of the second positioning rod 2-3 and the lower surface of the protrusion form an L-shaped positioning surface c for positioning the card holder 1-4, as shown in Figure 3.

[0031] The free end face of the third positioning rod 2-4 is the fourth positioning surface d, which is used to position the card holder 1-5;

[0032] The fourth positioning rod 2-5 has a fifth positioning surface e on one side for positioning the positioning bracket 1-6, and a sixth positioning surface f on the other side for positioning the positioning brackets 1-7 and 1-8.
