[0042] At least two positioning templates 6 are provided, with a through hole in the middle of the positioning template 6 and an annular positioning groove 7 on the top and outside of the positioning template 6. The at least two positioning templates 6 are stacked on top of the platform 3. The rotating mechanism can pass through the through hole. Adjacent positioning templates 6 are detachably connected. The outer diameter of the at least two positioning templates 6 gradually increases from bottom to top, and the inner diameter of the positioning groove 7 of the at least two positioning templates 6 gradually increases from bottom to top, so that an annular brake disc 1 of a certain size can be embedded inside the annular positioning groove 7 of each positioning template 6.

[0043] Specifically, to address the problem that existing assembly platforms have small brake disc support surfaces, making it prone to tipping over and unable to accurately position larger brake discs during assembly, necessitating the fabrication of the entire assembly platform and increasing assembly costs, this invention provides an assembly platform for electric locomotives. This platform has at least two positioning templates 6 stacked sequentially on top of the platform body 3. Adjacent positioning templates 6 are detachably connected. The outer diameters of the at least two positioning templates 6 gradually increase from bottom to top, and the inner diameters of the positioning grooves 7 of the at least two positioning templates 6 also gradually increase from bottom to top. When assembling the brake disc 1 and wheel 2 of a specific type of electric locomotive, the positioning template 6 corresponding to that type of electric locomotive can be placed on top, and then the brake disc 1 and wheel 2 of that type of electric locomotive can be assembled. The brake disc 1 is embedded in the positioning groove 7 of the positioning template. Then, the center hole of the wheel 2 is fitted onto the positioning post 5 and placed on the rotating end of the rotating mechanism. The wheel 2 can be rotated so that the indexing hole of the wheel 2 corresponds to the indexing hole of the brake disc 1. Then, the lifting mechanism is operated to lower the wheel 2 and fit it against the positioning template 6. At this time, the wheel 2 and the brake disc 1 can be assembled together by the locking device. The assembly table is designed with positioning templates 6 of various sizes. For the assembly of brake discs 1 of different sizes, the corresponding positioning template 6 can be found, which is not easy to tip over and can achieve precise positioning. The assembly of annular brake discs 1 of various sizes can be solved by one assembly table, which reduces the cost of remaking the assembly table and ensures that the assembly of brake disc 1 is completed efficiently and with high quality.

[0050] Bearing 11 is installed in the mounting slot;

[0051] Support plate 12 is disposed above the base 10 and connected to the rotating part of bearing 11. Support plate 12 is the rotating end of the rotating mechanism.

[0052] Specifically, the bearing 11 enables the wheel 2 on the support plate 12 to rotate so that the indexing hole of the wheel 2 corresponds to the indexing hole of the brake disc 1.

[0053] Preferably, the assembly platform for assembling electric locomotives further includes a limiting sleeve 13, the outer side of the limiting sleeve 13 being connected to the inner side of the cavity 4, and the outer side of the seat 10 being slidably connected to the inner side of the limiting sleeve 13.

[0054] Specifically, the limiting sleeve 13 is used to limit the seat 10 and prevent the seat 10 from shifting.

[0055] Preferably, the top of the limiting sleeve 13 and the top of the platform 3 are located on the same plane, and the positioning template 6 connected to the top of the platform 3 is also set on the top of the limiting sleeve 13.

[0056] Specifically, the top of the limiting sleeve 13 is also used to support the positioning template 6, thereby increasing the support strength of the positioning template 6.

[0057] like Figures 4-6 As shown, preferably, each positioning template 6 has a plurality of mounting holes 14 distributed in a circular pattern. The mounting holes 14 are used to pass through the locking member and connect at least two positioning templates 6 together.

[0058] Specifically, at least two positioning templates 6 can be fixedly connected by hexagon socket screws. Using hexagon socket screws for connection ensures connection strength while facilitating disassembly.

[0059] Preferably, the upper positioning template 6 of two adjacent positioning templates 6 has an annular mounting groove 15 at its bottom and on its inner side. When the two adjacent positioning templates 6 are fitted together, the annular mounting groove 15 of the upper positioning template 6 can fit with the top of the lower positioning template 6, and the annular positioning groove 7 of the lower positioning template 6 can fit with the bottom of the upper positioning template 6.

[0060] Specifically, the annular mounting groove 15 and the annular positioning groove 7 work together to achieve complete fit between two adjacent positioning templates 6, thus ensuring the stability of the connection between the two adjacent positioning templates 6.

[0066] Specifically, in order to ensure the assembly of brake disc 1 suitable for HXD3D electric locomotives, and to enable rapid conversion between brake disc 1 and HXD3 and HXD3C electric locomotives while maintaining center stability, the outer diameter of the positioning template 6 used to support the brake disc 1 of the HXD3D electric locomotive was calculated based on the drawings. Considering the space design of the torque wrench

[0067] To ensure proper positioning with the brake disc 1 of the HXD3D electric locomotive, the inner diameter of the annular positioning groove 7 was calculated by measuring the actual object. Considering the margin design is

[0068] In summary, the assembly platform for electric locomotive assembly provided by this utility model allows for the assembly of brake discs 1 and wheels 2 of a specific type of electric locomotive. A positioning template 6 corresponding to this type of electric locomotive can be placed at the top. The brake disc 1 of this type of electric locomotive is then embedded into the positioning groove 7 of the positioning template 6. The center hole of the wheel 2 is then fitted onto the positioning post 5 and placed on the rotating end of the rotating mechanism. The wheel can be rotated so that the indexing hole of the wheel 2 aligns with the indexing hole of the brake disc 1. The lifting mechanism is then operated to lower the wheel 2 and allow it to fit against the positioning template 6. At this point, the wheel 2 and brake disc 1 can be assembled together using locking components. This assembly platform is designed with positioning templates 6 of various sizes, ensuring that a corresponding positioning template 6 can be found for assembling brake discs 1 of different sizes. This prevents tipping and enables precise positioning. One assembly platform can solve the assembly of various sizes of annular brake discs 1.

[0069] This assembly station breaks away from the single function of existing assembly stations, achieving high efficiency in brake disc assembly and rapid conversion between brake disc assembly for different vehicle models. The dual positioning of the positioning pin 5 and the positioning groove 7 ensures the high-efficiency completion of the process.

[0070] Each positioning template 6 of the assembly station can stably support and precisely position a brake disc 1, making it convenient for operators to complete the assembly process of the brake disc 1, facilitating management, preventing personnel from being injured due to unstable support of the workpiece during operation, further ensuring the safe and efficient operation of the process, and saving assembly costs.

[0071] The various embodiments of the present invention have been described above. These descriptions are exemplary and not exhaustive, nor are they limited to the disclosed embodiments. Many modifications and variations will be apparent to those skilled in the art without departing from the scope and spirit of the described embodiments.
