Middle and lower part horizontal segment A, two symmetrical and circular segment B upwarped and two symmetrical upper horizontal end C.Side wall double fastener
The curved surface of the upper and lower edge contour wire shaped of plate 1-2 and the curve form of curb girder upper cover plate 1-1 with curb girder lower cover plate 1-3
The corresponding matching of profile wire shaped.
Curb girder 1 further includes two spring base 1-4 and two axle free bearing 1-5, and two spring base 1-4 are symmetrically fixed on
The both side ends of load girder construction.As shown in Figure 4 and Figure 5, axle free bearing 1-5 includes welding junction arc plate 1-5-1 and U-shaped
Axle bed 1-5-2, the circular segment B's of the circular arc segment profile line and curb girder lower cover plate 1-3 of welding junction arc plate 1-5-1
Curved surface profile wire shaped matches.The axle bed 1-5-2 of U-shaped is gate arch type, mainly includes on rear side of gate arch front side wall a or gate arch
Wall a, door pillar upper surface b, U-shaped double-side straight-line section end face c and gate arch arc surface d.If by a long side midpoint perpendicular to rectangle
Plane normal be defined as the long side middle vertical plane or midline plane of the rectangle, then as shown in Figure 6 and Figure 7, side wall double plate 1-2
One of sidewall paneling length direction on middle vertical plane be equipped with vertical center pin mechanism 1-2-1, the center pin mechanism
1-2-1 includes centrepin 1-2-1-1 and two pieces of centrepin gusset 1-2-1-1, and centrepin gusset 1-2-1-1 is along parallel center
The direction of pin 1-2-1-1 axis is welded on the lateral wall of centrepin 1-2-1-1, two pieces of centrepin gusset 1-2-1-1 institute each other
The angle for being in is 80 degree.The axis drawing standard span value of left and right two groups of axle free bearings 1-5 is K, left and right two spring base 1-
The drawing standard span value of 4 cylinder axis is T.
According to the assembly welding technique requirement of curb girder 1, four axle free bearing 1-5 are needed in pairs when making, left and right two
Group axle free bearing 1-5 passes through its respective welding junction arc plate 1-5-1 respectively and is symmetrically welded on curb girder lower cover plate 1-3's
Below circular segment B, also, the axis of gate arch arc surface d must be perpendicular to side wall double plate 1-2, four axle free bearing 1-
5 respective door pillar upper surface b be both needed to it is coplanar, and be located at ipsilateral each gate arch front side wall a also need it is coplanar.
Due to the structure of curb girder upper cover plate 1-1, curb girder lower cover plate 1-3, its three's curve of side wall double plate 1-2 or curved surface
Particularity, it is relatively difficult and complicated to lead to carry out group load girder construction early period the Set and Positioning operation before weldering, load girder construction
Group postwelding, the welding deformation amount of the circular segment B of curb girder lower cover plate 1-3 is larger, and symmetry is poor, this further results in two
The positioning of group axle free bearing 1-5 and welding difficulty increase, and need largely to survey and draw scribing line operation, moreover, when welding cooling
Under metamorphosis, the welding posture of axle free bearing 1-5 and position are difficult to effectively keep, therefore deviation often occur, it is necessary to volume
Outer increase correction adjusting operation could guarantee welding quality reluctantly.
On the other hand, existing to determine two groups of axle free bearing 1-5 and two spring base 1-4 with when bearing beam structure welding
Position operation is all made of curb girder formal dress posture as shown in Figures 1 to 4, but axle free bearing 1-5 will receive certainly under the formal dress posture
The influence of body gravity and interfere the group of its welding junction arc plate 1-5-1 to positioning accuracy, meanwhile, the formal dress welding posture
It is unfavorable for brazing metal when melting to repeat among filling weld seam, and then influences welding quality.If curb girder is changed to shown in Fig. 8
Anti- dress posture, then reduce mapping dashing work, and can exempt gravity to weld seam group to and welding fluid filling influence, thus
Preferably solve foregoing problems.
For this purpose, a truck side sill welding assisted group fast positioned for axle free bearing of research and development exists to positioning tool gesture
It must go.

The both ends of locating rod 5-2 pass through the bolt top column hinged block 5-1 corresponding with one respectively and are connected, and point adjusting is left and right
Horizontal ends grease head highness adjustment bolt 2-2 in two horizontal ends grease head highness adjustment bolt groups, so that curb girder upper cover plate 1-1 meets
Group makes left and right two groups of axle free bearings 1-5 pass through its respective welding junction arc plate 1- respectively required horizontal attitude
5-1 is symmetrically aligned in below the circular segment B of curb girder lower cover plate 1-3.It is laterally fixed by each curb girder upper cover plate respectively again
Two curb girder upper cover plates in the mechanism of position laterally hold out against former and later two directions screw mechanism 2-1, and curb girder upper cover plate 1-1 is lateral
It holds out against, to complete to the group of the standard welding posture of load girder construction to positioning.Due to two axle free bearing gate arch locators
Axis standard span value of 5 distance values equal to left and right two groups of axle free bearings 1-5 is K, and therefore, above-mentioned positioning is to left and right two
The positioning operation of the axle bed 1-5-2 of group U-shaped also realizes the sizing for complying with drawing standard span K simultaneously.So far,
It can start to complete left and right two groups of axle free bearing 1-5 the weld job under anti-dress posture.Institute's group under the anti-dress posture
Pair axle free bearing 1-5 not will receive the influence of self gravity and interfere, therefore the group pair of its welding junction arc plate 1-5-1
Positioning accuracy can be improved, meanwhile, this instead fills the brazing metal that welding posture is also beneficial to when melting and repeats filling weld seam
Among, and then improve welding quality.
Using spring base hold-down mechanism 4 by corresponding spring base 1-4 with the anti-attitude orientation filled in its position
Curb girder upper cover plate 1-1 upper horizontal end C on, make spring base 1-4 cylinder periphery wall and side wall double plate 1-2
Two inner sidewall ends it is tangent respectively, flexible spring seat clamping pad block 4-5 and make thereafter through turning beam pivoted arm 4-3 band
Its top edge that its cylinder is pressed in along the diametrical direction of spring base 1-4, finally, making retaining mechanism screw rod 4-4-1 around rotational pin
The axis of axis 4-4-3 is rotated and is embedded in clamping screw card slot 4-3-1, and makes its lower end surface by rotating locking nut 4-4-2
It is pressed in the upper end of clamping screw card slot 4-3-1, can complete to make left and right two spring bases by crossbeam pivoted arm retaining mechanism 4-4
1-4 is completed with the standard welding posture group of load girder construction according to the drawing standard span value T of the cylinder axis of the two to fixed
Position operation, so far, it can start to complete left and right two spring base 1-4 the weld job under anti-dress posture.
