[0042] Tooling base 1;

[0043] A screw clamp 2 integrated at one end of the tooling base 1, the screw clamp 2 is used to clamp the tail of the brake beam; and

[0044] A plurality of groups of supporting cylinders are integrated at the other end of the tooling base 1, and the supporting cylinders are used to support the lower surface of the head of the brake beam.

[0045] Specifically, this embodiment discloses a tooling for welding the brake beam connecting arm of a CRH5 EMU, which includes a tooling base 1, a screw clamp 2, and multiple groups of support cylinders; the tooling is mainly used to adapt to the requirements of the tail clamping and positioning of the new brake beam and the head bending bottom surface support. Therefore, after the brake beam is placed on the tooling, the screw clamp 2 is used to position and fix the tail of the brake beam, and because the head of the brake beam extends forward in a curved manner, multiple groups of support cylinders are used to support different positions of the head of the brake beam to meet the support requirements, which fully meets the positioning and support requirements of the new brake cylinder.

[0046] Preferably, the tooling base 1 of this embodiment includes:

[0047] a bottom plate 101; and

[0048] A tooling plate 102 connected to the upper portion of the bottom plate 101 through a vertical plate 103;

[0049] The lead screw fixture 2 and the supporting cylinder are both arranged on the tooling plate 102 .

[0050] First, this embodiment further defines the composition of the tooling base 1, which includes a bottom plate 101 and a tooling plate 102, and the bottom plate 101 and the tooling plate 102 are welded together through the vertical plates 103 on both sides to form a support frame, the upper end of which is a tooling plate that integrates the above-mentioned screw clamp 2 and multiple support cylinders.

[0051] Preferably, the lead screw clamp 2 of this embodiment is assembled and fixed to one end of the tooling plate 102;

[0052] The lead screw clamp 2 includes:

[0055] A lead screw 204 is installed at one end of the clamp arm 203 away from the assembly plate 201 , and the lower end of the lead screw 204 is a pressing end. The lead screw 204 is threadedly connected to the clamp arm 203 to adjust the height of the pressing end.

[0056] In this embodiment, long holes 202 are opened on both sides of the assembly plate 201 , and the assembly plate 201 is assembled and fixed to the tooling plate 102 by fastening bolts installed in the long holes 202 .

[0057] This embodiment further defines the structure of the lead screw clamp 2, which is assembled and fixed with the tooling plate 102 through the assembly plate 201. Specifically, long holes 202 are opened on both sides of the assembly plate 201 as mounting holes, and the assembly position can be adjusted by the cooperation of the fastening bolts and the long holes 202. The clamp arm 203 is an L-shaped structure, extending toward one side of the supporting cylinder, and the end of the clamp arm 203 is threadedly connected with a lead screw 204, and the end of the lead screw 204 is a pressing end that contacts the upper surface of the rear end of the brake beam and presses the rear end of the brake beam.

[0058] Preferably, the tooling plate 102 of this embodiment is provided with two supporting cylinders on the side away from the screw clamp 2;

[0059] The two supporting cylinders are divided into a first supporting cylinder 301 and a second supporting cylinder 302;

[0066] Since the new brake beam is a curved structure as a whole, and one end of its head is bent and extended upward, the distance between the head of the brake beam and the tooling plate 102 gradually increases. Therefore, this embodiment designs two support cylinders with different diameters to support different positions of the brake beam.
