[0028] 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.

[0029] See also Figure 1-3 As shown;

[0030] The utility model discloses an adjustable beam assembly supporting device, comprising:

[0031] A support 10 and an axial slide plate 20 mounted on the upper portion of the support 10;

[0032] The axial slide plate 20 includes a horizontal section 21 and a vertical section 22;

[0033] The upper surface of the horizontal section 21 is a bearing surface for supporting the crossbeam;

[0034] The horizontal section 21 overlaps with the upper surface of the support 10, and the bottom end surface of the vertical section 22 is coplanar with the lower surface of the support 10, so that the axial slide 20 is displaced along the axis of the beam, the horizontal section 21 remains in contact with the upper surface of the support 10, and the vertical section 22 is supported on one end of the horizontal section 21 to keep the horizontal section 21 parallel to the horizontal plane.

[0035] For details, see Figure 4 As shown, in this structure, the support 10 can be fixedly connected to the base plate of the beam assembly tooling. Of course, the beam assembly support device can also be installed on other tooling through the support 10. This embodiment only takes the beam assembly tooling as an example. An axial slide plate 20 is installed on the upper part of the support 10 to support the beam.

[0036] See also Figure 1 , 2As shown, the structure of the axial slide plate 20 is an inverted L-shaped structure, and the angle between the horizontal section 21 and the vertical section 22 is 90°. The upper surface of the horizontal section 21 of the axial slide plate 20 is a bearing surface, and the crossbeam is supported by the bearing surface. When in use, the horizontal section 21 overlaps the upper surface of the support 10, and the vertical section 22 is fixedly connected to one end of the horizontal section 21. The bottom end surface of the vertical section 22 and the lower surface of the support 10 can synchronously support the horizontal section 21. Therefore, when the axial slide plate 20 is displaced along the axis of the crossbeam, the horizontal section 21 always keeps in contact with the upper surface of the support 10 and keeps parallel to the horizontal plane, thereby increasing the axial support stroke of the assembly support device. The operator can achieve the purpose of assembling and welding crossbeams of different lengths on the same tooling through simple axial adjustment.

[0037] See also Figure 2 As shown:

[0038] Preferably, the pair support device further includes a fixing assembly 30 for fixing and connecting the horizontal section 21 and the support 10 at any position, so as to further ensure the supporting stability of the pair support device.

[0039] The fixing assembly 30 includes a bolt 31 and a nut 32 connected to the bolt 31 . The horizontal section 21 and the support 10 are both provided with a long hole connected to the bolt 31 . The long hole on the horizontal section 21 is a countersunk hole.

[0040] See also Figure 1 As shown:

[0041] Preferably, a pad 23 is fixedly connected to the upper surface of the horizontal section 21, and a protrusion 24 is provided on one side of the pad 23. When in use, the protrusion 24 contacts the side wall of the beam to prevent the beam from detaching from the surface of the axial slide plate 20 when the tooling clamps the beam.

[0042] Preferably, a reinforcing plate 25 is fixedly connected to the side of the vertical section 22 away from the support 10, and the lower surface of the reinforcing plate 25 is coplanar with the support 10. In this structure, the overall structural strength of the axial slide plate 20 is improved by the reinforcing plate. At the same time, by setting the lower surface of the reinforcing plate 25 coplanar with the support 10, the contact area between the vertical section 22 and the tooling substrate can be increased, thereby improving the support reliability.

[0043] See also Figure 1 Shown

[0044] Preferably, the support 10 includes a bottom plate 11, a seat plate, and a vertical plate 12;

[0045] The seat plate is arranged parallel to the base plate 11, and the two ends of the lower part of the seat plate are fixedly connected to the base plate 11 through the vertical plates 12, wherein the projection area of ​​the base plate 11 on the horizontal plane is larger than the projection area of ​​the seat plate, and a mounting hole 13 is opened at the edge of the base plate 11, and bolts are installed through the mounting hole for fixed connection with the base plate of the tooling, and the mounting hole 13 is a U-shaped hole for easy assembly.

[0046] In the above technical solution, the utility model provides an adjustable beam assembly supporting device, and the method of use is:

[0047] When in use, the pair of support devices is fixedly connected to the tooling base plate through the bottom plate 11 of the support 10, so that the position of the pair of support devices is fixed.

[0048] When assembling beams of different lengths, the axial slide plate 20 is slid along the axial direction of the beam to change the initial support position of the assembly support device, and the axial stroke of the assembly support device is increased by axially adjusting the axial slide plate 20;

[0049] After the position of the axial slide plate 20 is adjusted, the horizontal section 21 of the axial slide plate 20 and the seat plate of the support 10 are fixedly connected by the fixing assembly 30, so that the axial slide plate 20 and the support 10 become one body;

[0050] Finally, after the cross beam is placed on the bearing surface of the axial slide plate 20 , one side of the cross beam abuts against the protrusion 24 on one side of the axial slide plate 20 .

[0051] The adjustable crossbeam pairing support device effectively eliminates the drawbacks of fixed axial dimensions, and realizes that the same tooling can be integrated and used in the crossbeam pairing of the AS series bogies of urban railway vehicles. The operator can use the axial dimension adjustment function of the crossbeam pairing device to meet the needs of various crossbeam pairings of the AS bogie platform. It has the advantages of compact structure, low cost, small operation space, simple and fast operation, strong environmental adaptability, and can improve production efficiency and quality.

[0052] Through the use of the support device by this group, the number of times the beam group has to modify and re-make the tooling can be greatly reduced. According to the cost of the new and modified system, the direct economic benefit of avoiding the new system is 40,000 yuan per time. The indirect economic benefit of avoiding the modification = direct economic benefit * number of projects per year (calculated based on 10 new urban rail projects per year) + single tooling production cost = 4*10+10000 = 410,000 yuan.

[0053] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
