A slight deviation will cause dimensional errors in subsequent CNC machining and the vehicle cannot be assembled, resulting in the scrapping of the workpiece and delaying the construction period. Moreover, the consistency of manual marking is also difficult to guarantee. Utility Model Content

[0025] The utility model relates to an assembling device for a stabilizer wheel mounting seat of a railway passenger car bogie, which comprises: a bracket 2;

[0026] The bracket 2 is constructed in a toroidal structure. A central positioning and stopping structure 5 is formed on the inner ring surface of the bracket 2, which can extend into a cylinder 8 of the stabilizer wheel 1 and fit with the inner wall of the cylinder 8. Through the central positioning and stopping structure 5, the bracket 2 is concentric with the cylinder 8, ensuring the accurate position of the bracket 2 on the stabilizer wheel 1;

[0027] A side positioning and stopping structure 6 is formed on the outer ring surface of the bracket 2 and extends downward to fit with the vertical plate of the outer convex section of the stabilizer wheel 1. Through the side positioning and stopping structure 6, the rotation of the bracket 2 around the vertical axis of the cylinder 8 is stopped, thereby restricting the rotational displacement of the bracket 2;

[0028] A through hole is provided in the bracket 2 corresponding to the position of the mounting seat 4 of the stabilizer wheel 1; A connecting member 3 is inserted into the through hole. The connecting member 3 is a hexagon head bolt or a pin shaft with an external thread. The connecting member 3 passes through the through hole and is connected to the threaded hole of the mounting seat 4;

[0029] In this structure, the bracket 2 is connected to the mounting seat 4 through the connecting member 3, so that the mounting seat 4 and the bracket 2 form an integral body, which not only realizes the synchronous positioning of eight mounting seats 4 at one time, improves the positioning efficiency, but also ensures the dimensional consistency of the mounting seats 4 during mass production;

[0030] In a preferred embodiment, the central positioning and stopping structure 5 is a positioning plate constructed in an L-shaped structure and evenly distributed circumferentially along the inner ring surface of the bracket 2.

[0031] In a preferred embodiment, the side positioning and stopping structure 6 includes a first plate body fixedly connected to the bracket 2. A second plate body 7 is fixedly connected to one side of the first plate body 7. The second plate body 7 extends towards the vertical plate of the convex section of the stabilizer wheel 1. During use, the rotation displacement of the bracket 2 is stopped by the end of the second plate body 7 abutting against the vertical plate of the convex section of the stabilizer wheel 1;

[0032] In a preferred embodiment, the bracket 2 further includes a first extension section and a second extension section;

[0033] The inner ring surface of the bracket is formed with a first extension section extending towards the central axis of the cylinder 8, and the outer ring surface of the bracket is formed with a second extension section extending away from the central axis of the cylinder 8. A central positioning and stopping structure 5 is fixedly connected to the first extension section, and a side positioning and stopping structure 6 is fixedly connected to the second extension section, thereby facilitating the lightweight design of the device.

[0034] Preferably, one side of the bracket 2 is formed with a notch capable of accommodating a hand, and the bottom of the notch is connected with a linear connecting section 9. During use, the hand can hold the connecting section 9 to pick up the bracket 2, which is convenient to use.

[0035] In the above technical solution, for the device for assembling the mounting seats of the stabilizer wheels of the railway passenger car bogie provided by the utility model, the using method is as follows:

[0036] Figure 1 as shown:

[0037] During operation, first, the mounting seats 4 to be assembled are tightened on the connecting members 3 of the bracket 2 one by one, so that the mounting seats 4 and the assembling device form a whole, and then the whole of the bracket 2 and the mounting seats 4 is placed at the upper cover plate of the stabilizer wheel 1;

[0038] The four positioning and stopping structures 5 of the bracket 2 are clamped into the inner wall of the cylinder 8 of the stabilizer wheel, and the side positioning and stopping structure 6 is attached to the vertical plate of the stabilizer wheel 1 to form positioning. At this time, the position where the mounting seat 4 is located is exactly at the set position and its welding point is fixed. After spot welding, the connecting member 3 is rotated to disengage it from the mounting seat 4 and the assembling device is removed, thus completing the assembling process.
