[0035] 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 with reference to the accompanying drawings.

[0036] See also Figures 1 to 3 As shown;

[0037] This embodiment provides a universal tool for welding, grinding, and steel grade engraving of an auxiliary mounting seat for an EMU, the tool comprising:

[0038] Work surface 1; and

[0039] A support structure integrated into one side of the worktop 1;

[0040] One end of the support structure is a mounting portion that cooperates with the EMU auxiliary mounting seat 10, and the other end is an operating portion;

[0041] The operating part can drive the mounting part to rotate so as to drive the EMU auxiliary mounting seat 10 fixed thereon to rotate;

[0042] The operating portion can be locked by a lock nut 5 to lock the mounting portion.

[0043] Specifically, this embodiment discloses a universal tooling for welding, grinding, and steel grade marking of EMU auxiliary mounting seats. This tooling primarily meets the requirements for rotating the EMU auxiliary mounting seat 10 during welding and grinding, as well as maintaining the EMU auxiliary mounting seat in a locked state to facilitate forceful hammering during steel grade marking. Therefore, the tooling of this embodiment includes a tooling table 1 and a support structure integrated with the tooling table 1. The support structure includes a mounting portion that cooperates with the EMU auxiliary mounting seat 10, and an operating portion that drives the mounting portion to rotate.

[0044] Preferably, the support structure of this embodiment is fixed to the side of the workbench 1 through a vertical rod 2; an adjusting nut 4 is fixed to the vertical rod 2;

[0045] The adjusting nut 4 is rotatably connected to a transverse adjusting screw 3, which extends to the outside of the tooling table 1 and is integrated with a mounting portion at one end.

[0046] The lateral adjustment screw 3 extends to one end inside the tooling table 1 as the operating part;

[0047] A locking nut 5 is mounted on the transverse adjustment screw 3 .

[0048] First, this embodiment further defines the overall structural composition of the support structure, which is fixed to the side of the tooling table 1 through the vertical rod 2, and an adjustment nut 4 is fixed to the upper end of the vertical rod 2. The adjustment nut 4 of this embodiment can be two nuts welded together, and at the same time, the transverse adjustment screw 3 is rotatably connected to the adjustment nut 4. In order to achieve the locking of the transverse adjustment screw 3 when the steel grade is engraved, a locking nut 5 is threadedly connected to the transverse adjustment screw 3. By tightening the locking nut 5 to a position against the adjustment nut 4, the transverse adjustment screw 3 can be locked, thereby maintaining the position of the mounting portion and ultimately maintaining the position of the EMU auxiliary mounting seat 10, that is, the locking nut 5 is threadedly connected to the transverse adjustment screw 3. When the locking nut 5 is against the adjustment nut 4, the transverse adjustment screw 3 is locked to lock the transverse adjustment screw 3 and the adjustment nut 4. In addition, the locking structure of this embodiment is not unique. As long as it is a structure that can limit the rotation of the transverse adjustment screw 3, it meets the use requirements of the tooling of this application and will not be repeated here.

[0049] Preferably, the mounting portion of this embodiment includes a mounting plate 601 connected to the end of the transverse adjustment screw 3; and a pressing plate 602 connected to the mounting plate 601 via two adjustment bolts 603;

[0050] The space between the pressing plate 602 and the mounting plate 601 is used to clamp the corresponding position of the EMU auxiliary mounting seat 10, and the pressing plate 602 can pass through the hollow portion 11 in the middle of the EMU auxiliary mounting seat 10 and extend to the outside of the EMU auxiliary mounting seat 10;

[0051] The relative position of the pressing plate 602 and the mounting plate 601 is adjusted by adjusting bolts 603 .

[0052] In this embodiment, the pressure plate 602 is provided with open insertion grooves 604 at both ends;

[0053] The adjusting bolt 603 extends into the slot from the open embedding slot 604 and connects the pressing plate 602 and the mounting plate 601 .

[0054] This embodiment further defines the structure of the mounting portion, which includes a mounting plate 601 and a pressure plate 602. Two adjusting bolts 603 are provided in the pressure plate 602. The relative positions of the pressure plate 602 and the mounting plate 601 can be adjusted by adjusting the bolts 603 to achieve clamping and fixation of the EMU auxiliary mounting seat 10.

[0055] In the above technical solution, the utility model provides a universal tool for welding, grinding, and steel grade engraving of the auxiliary mounting seat of an EMU, which has the following beneficial effects:

[0056] The universal tooling of the utility model can adjust the welding position to the optimum by using a screw as an adjusting component, thereby realizing continuous welding, reducing joints, and lowering the workload of post-weld grinding. The steel number is placed firmly when being engraved, which is conducive to exerting force to hammer the steel number.

It goes without saying that those skilled in the art will be able to modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
