Technical Field
[0001] This utility model relates to the field of rail passenger vehicle manufacturing technology, and in particular to a tooling for assembling end beams on a frame. Background Technology
[0002] In the past, bogie frames were mostly H-shaped structures. These frames were relatively easy to assemble as they did not have end beams. However, when assembling frames with end beams, the side beams were prone to twisting, and the end beam tubes were easily rotated, making it difficult to position the components in space, thus hindering the achievement of the required assembly precision. Therefore, those skilled in the art need to develop a tooling for assembling end beams on the bogie frame. Utility Model Content
[0003] The purpose of this invention is to provide a tooling for assembling end beams on a frame. This tooling can meet the accuracy requirements for assembling end beams, reduce the number of disassembly and assembly operations, and utilizes a sliding track design to achieve flexible assembly between end beams and between end beam components. Furthermore, it relies on the machining holes of the brake hanger and the positioning pins on the tooling to ensure the dimensional accuracy of the end beams. This tooling can prevent the problem of the end beams and their components being asymmetrical, which would lead to the end beams not meeting the dimensional accuracy requirements for assembly, thereby improving labor efficiency and reducing repetitive labor such as disassembly and assembly operations.

[0047] See Figures 1 to 4 As shown;
[0048] This embodiment provides a tooling for assembling end beams on a frame. This tooling is applicable to the assembly process of the H-shaped frame 10. The tooling includes:
[0049] Tooling base 1;
[0050] A beam positioning fixture assembly is integrated in the middle area of the tooling base 1. The beam 11 of the H-shaped frame 10 is placed and positioned and fixed in the middle area of the tooling base 1 through the beam positioning fixture assembly.
[0051] A left-side end beam assembly slide rail 201 extends along the length of the tooling base 1 and is located on the left side of the tooling base 1; a right-side end beam assembly slide rail 202 extends along the length of the tooling base 1 and is located on the right side of the tooling base 1; a left-side end beam positioning clamp assembly 3 is slidably connected to the left-side end beam assembly slide rail 201, and a right-side end beam positioning clamp assembly 4 is slidably connected to the right-side end beam assembly slide rail 202; and

A left beam positioning clamp assembly 6 is slidably connected to the left beam pairing slide rail, and a right beam positioning clamp assembly 7 is slidably connected to the right beam pairing slide rail 203.
[0053] When assembling the end beams of the H-shaped frame 10, the corresponding end beam positioning fixture assembly and the position of the end beam relative to the side beam are adjusted by the slide rail through the corresponding end beam assembly.
[0054] When assembling the side beams of the H-shaped frame 10, the corresponding side beam positioning fixture assembly and the position of the side beam relative to the crossbeam 11 are adjusted by the corresponding side beam assembly slide rail.
[0055] Specifically, this embodiment discloses a tooling for facilitating the assembly of end beams. Its bottom is a tooling base 1, on which slide rails are arranged along the X and Y directions, respectively, to correspondingly adjust the positions of the side beams, end beams, and corresponding clamps. In this embodiment, the left and right sides are defined based on the X and Y directions. That is, along the Y direction, it is divided into a left end beam 12 and a right end beam 13; similarly, along the X direction, it is divided into a left beam 14 and a right beam 15. The structure of the tooling in this application is further explained according to this division standard. The tooling base 1 of this embodiment integrates a slide rail 201 for assembling the left end beam, a slide rail 202 for assembling the right end beam, a slide rail for assembling the left beam, and a slide rail 203 for assembling the right beam. Simultaneously, corresponding positioning clamping assemblies are slidably engaged with the corresponding slide rails. These positioning clamping assemblies are positioned and clamped at corresponding positions on the H-shaped frame 10 for assembly operations.
[0056] Preferably, the tooling base 1 in this embodiment includes a base body 101 and a support leg 102 supported on the bottom of the base body 101; the left end beam pairing slide rail 201, the right end beam pairing slide rail 202, the left beam pairing slide rail and the right beam pairing slide rail 203 are all assembled and fixed to the corresponding positions of the base body 101 by fasteners.
[0057] Preferably, the left end beam positioning fixture assembly 3 of this embodiment includes a left end beam positioning reference plate 301 slidably connected to the left end beam assembly slide rail 201; and a left end beam end positioning fixture 302 arranged at both ends of the left end beam positioning reference plate 301; and a brake hanger positioning structure is provided at the position where the left end beam positioning reference plate 301 and the brake hanger 16 of the left end beam 12 cooperate.
[0058] Secondly, the right end beam positioning fixture assembly 4 of this embodiment includes a right end beam positioning reference plate 401 that is slidably connected to the right end beam assembly slide rail 202; and right end beam end positioning fixtures 402 arranged at both ends of the right end beam positioning reference plate 401; and a brake hanger positioning structure is provided at the position where the right end beam positioning reference plate 401 and the brake hanger 16 of the right end beam 13 are engaged.
[0059] To further enhance the positioning reference and improve assembly accuracy, this embodiment designs a brake hanger positioning structure that mates with the brake hanger 16. Specifically, the brake hanger positioning structure of this embodiment includes:
[0060] Brake hanger limit seats 501 are arranged at intervals, and the space between two adjacent brake hanger limit seats 501 is the passage space for the brake hanger 16 of the end beam. The brake hanger 16 extends to the inner side of the upper end of the brake hanger limit seat 501, and the brake hanger hole 1602 of the brake hanger 16 is connected to the corresponding brake hanger limit seat 501 through the brake hanger hole positioning pin 502.

[0062] Secondly, the right beam positioning fixture assembly 7 of this embodiment includes a right beam positioning reference plate 701 that is slidably connected to the right beam assembly slide rail 203; and right beam end positioning fixtures 702 arranged at both ends of the right beam positioning reference plate 701.
[0063] Taking the end beam as an example, the Z-axis can be positioned using the end beam positioning reference plate and the end beam positioning fixture. Simultaneously, the Y-axis dimension of the end beam is positioned using the holes on the brake hanger 16, and the X-axis dimension is positioned using the brake hanger positioning seat. The connection between the end beam and the side beam ends is achieved using the corresponding slide rail interface. The adjustment of the side beam follows the same principle. This completes the end beam assembly process.
[0064] In the above technical solution, the tooling for assembling end beams on a frame provided by this utility model has the following beneficial effects:
[0065] The tooling of this utility model can meet the accuracy requirements of the frame end beam assembly, reduce the number of disassembly and assembly, and realize flexible assembly between frame end beams and between the frame and the various components of the end beam by utilizing the slide rail design. Furthermore, it relies on the cooperation between the machining hole of the brake hanger and the positioning pin on the tooling to ensure the dimensional accuracy of the end beam. This tooling can prevent the problem of the end beam and its components being asymmetrical, which would cause the dimensional accuracy of the end beam assembly to fail to meet the usage requirements, improve labor efficiency, and reduce repetitive labor such as disassembly and assembly.
[0066] The tooling of this utility model utilizes the precision-machined holes and machined surfaces of the end beams as positioning references, resulting in more accurate dimensions. During the assembly of the end beams, the ingenious design of the slide rail allows for the separation of the end beams from the side beams at any time on the slide rail if interference occurs in individual parts, affecting the assembly dimensions. This reduces repetitive labor such as multiple hoisting and disassembly, as well as repeated positioning, and prevents the end beams from tipping over due to their asymmetrical structure. This significantly reduces labor intensity and improves production efficiency.
[0067] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
