[0026] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0027] See also Figure 1 As shown;

[0028] The utility model discloses a tool suitable for assembling an axle box of a city railway vehicle bogie, comprising: a bracket body 1, a support 2, and a positioning structure 3;

[0029] The bottom of the bracket body 1 is in contact with the ground, and the upper part of the bracket body 1 is provided with branch pipes extending upward and of different heights. The top end of the branch pipe can be fixedly connected to the support 2 at any height through the positioning structure 3. The top end of the support 2 has a limiting platform 21 extending radially along the branch pipe, and is in contact with the axle box body through the limiting platform 21.

[0030] For details, see Figure 2 , 3 As shown, the support 2 includes a limiting platform 21 and a connecting rod, the connecting rod is a stud, the limiting platform 21 is made of a steel plate, the lower part of the limiting platform 21 is welded with a stud, and a cube that cooperates with a wrench is processed on the top of the stud. The stud of the support 2 is connected to the branch pipe on the bracket body 1 through a positioning structure 3;

[0031] The positioning structure 3 includes a locking piece and a threaded tube 32. The locking piece is a locking nut 31 in the prior art. The threaded tube 32 is fixedly connected to the top of the branch pipe. The limiting platform 21 is threadedly connected to the threaded tube 8 through a connecting rod, so that the lifting and lowering adjustment can be achieved. After the support 2 is adjusted to the appropriate size, it is fixed using the locking nut 31.
