Embodiment 1

[0035] Such as Figure 4 , Figure 5 As shown, the present invention provides a positioning tool for rail vehicle frame side beams, the tool has:

[0036] Bearing beam 1, such as Figure 6 As shown, there is a beam body 11 in the shape of a quadrangular column and mounting plates 12 fixed at both ends of the beam body 11. The beam body 11 consists of two spaced end plates 111 and two side plates 112 crossing the end plates 111 respectively. Enclosed, two T-shaped grooves 13 are provided on the side plate 112 along its length direction;

[0037] A plurality of U-shaped basic units 2, each of which has a vertical plate 21 and two hanging plates 22, the ends of the two hanging plates 22 are respectively connected to the two ends of the vertical plate 21 to form a U shape, the vertical plate 21 is installed on the load beam 1 through two sets of bolts 23 placed in the T-shaped groove 13;

[0038] At least two cover plate positioning units 3, each of which is T-shaped and has a...

Embodiment 2

[0052] On the basis of Embodiment 1, in order to further increase the stability of the upper cover plate, the inner vertical plate, the outer vertical plate, and the two end plates, two second pressing units 8 are added to the inner vertical plate, the outer vertical plate and the upper cover The plate is pressed, such as Figure 4 , 5 , 17; the second compression unit has two supporting columns 81, two ends are respectively fixed on the cross beam 82 at the top of the two supporting columns 81 and at least one third compression screw on the span beam 82 Column 83, such as Figure 18 As shown, the span beam 82 can rotate 360 ​​degrees around any supporting column 81, which is convenient for installation. During installation, at first the bottoms of the two support columns 81 can be fixed on the suspension plates 22 of the U-shaped foundation unit 2 on both sides of the load beam by bolts, and then the third compression studs 83 can be made by rotating the top of the third co...

Abstract

The invention relates to a positioning tool for railway vehicle framework side frames. The positioning tool consists of a carrier bar, multiple U-shaped base units installed on a side plate of the carrier bar, at least two cover plate positioning units for positioning upper cover plates and lower cover plates of the side frames, an end plate positioning unit for positioning the lower cover plate and an end plate, multiple clapboard positioning units for positioning clapboards, multiple first and second pressing units for pressing the side frames, multiple first compressing units for pressing the side frames, and multiple pressing plate units for pressing the lower cover plates of the side frames, wherein the cover plate positioning units, the clapboard positioning units and the pressing units can be installed on the U-shaped base units, and the first pressing units can be installed on the U-shaped base units or the pressing units; and the end plate positioning unit and the pressing plate units are all installed on the end plate of the carrier bar. As the positioning tool adopts a turnover structure, compared with the prior art in which the assembly of the side frame is completed by means of multiple platform tools, the positioning tool can be used for completing the assembly of the two side frames at a time, and meanwhile, a welding operation can be carried out.
