Embodiment one
Fig. 1 is the front view when group of industrial-mineral electric locomotive axle box square hole that the utility model embodiment provides works to tooling
And vertical view, Fig. 2 is the front view and vertical view of the vehicle frame of industrial-mineral electric locomotive that the utility model embodiment provides, with reference to figure 1
Shown in Fig. 2, the group of industrial-mineral electric locomotive axle box square hole provided by the utility model is to tooling, for assembling the vehicle of industrial-mineral electric locomotive
Frame 200, vehicle frame 200 include the left plate 21 being oppositely arranged and right plate 22, front axle 23 are corresponded on left plate 21 and right plate 22
With two axle box square holes 25 are respectively arranged at rear axle 24,
Group includes tooling 100：Positioned at the lower section of vehicle frame 200 tooling platform 10 and be detachably arranged in tooling platform 20
Top surface two positioning components 11, two positioning components 11 are correspondingly arranged at the axle box square hole 25 of front axle 23 and rear axle 24 respectively
Axle box square hole 25 in, each positioning component 11 includes the fixture block 12 that can be fitted into axle box square hole 25 and is detachably arranged in
Multiple adjusting blocks 13 on fixture block 12, adjusting block 13 are mounted on the one side towards 25 lateral margin of axle box square hole of fixture block 12, wherein, card
Block 12 is more than the distance between left plate 21 and right plate 22, positioning component in the length on 200 length direction of vehicle frame
The gap for positioning axle box riser 26 is formed between 12 and corresponding axle box square hole 25.
It is to be appreciated that the vehicle frame 200 of industrial-mineral electric locomotive includes the left plate 21 being oppositely arranged and right plate 22, left side
Front end-plate, end plate and each crossbeam (not shown) are welded between plate 21 and right plate 22.In the prior art, industrial and mineral electricity
The group of the vehicle frame 200 of locomotive is that riveter crosses according to drawing to mode, first erects left plate 21 and right plate 22 in tooling
On platform, welder welds block to the layout line, the front end-plate that then connects and welds, end plate and each crossbeam.Next by vehicle frame
200 rollovers so that upward, riveter corresponds to front axle 23 to side plate on left plate 21 and right plate 22 and the position of rear axle 24 is enterprising
The scribing line of row axle box square hole 25, and cut axle box square hole 25.After completing cutting, it is close to the 25 edge welding spindle of axle box square hole of cutting
Case riser 26.
In the present embodiment, before cutting axle box square hole 25 the step of and method are identical with the above-mentioned prior art.Axle box side
After cutting is completed in hole 25, need the entire card of vehicle frame 200 and group using overhead traveling crane in tooling 100 so that positioning component 11
In in axle box square hole 25.And need the position using the tools such as jack adjustment vehicle frame 200 so that 200 length direction of vehicle frame
On central axes the central axes of tooling 100 are overlapped with group.Next, it needs axle box riser 26 being caught in axle box square hole 25 and group
Between tooling 100, i.e., between axle box square hole 25 and positioning component 11, axle box riser 26 is close to positioning component 11, and axle box is stood
Plate 26 is welded on the edge of axle box square hole 25.If the gap between axle box square hole 25 and positioning component 11 is excessive, need at it
In sheet metal of jumping a queue weld again；If positioning component 12 is close in gap within claimed range, in guarantee axle box riser 26
In the case of directly weld.
Specifically, positioning component 11 includes fixture block 12 and the multiple adjusting blocks 13 being detachably arranged on fixture block 12, i.e.,

It disturbs, so as to promote assembling precision.Further, fixture block 12 along the size on length over ends of body direction is being less than axle box square hole 25
Width so that fixture block 12 can be completely accommodated in axle box square hole 25, the gap of fixture block 12 and axle box square hole 25, for accommodating axle box
Riser 26 is close to fixture block 12 and welds axle box riser 26, it is ensured that the depth of parallelism and dimensional accuracy of axle box riser 26.
In the present embodiment, the quantity of the adjusting block 13 in every one side towards 25 lateral margin of axle box square hole of fixture block 12 is at least
Two, and at least two adjusting blocks 13 are arranged along the short transverse of fixture block 12.Specifically, the effect of adjusting block 13 is to adjust positioning
Component 11 makes positioning component 11 be adapted to various sizes of axle box square hole 25 along the size on 200 length direction of car body.It is welding
During axle box riser 26, need axle box riser 26 being close to adjusting block 13, therefore, the adjusting block 13 in the short transverse of fixture block 12
Quantity at least two, stability and precision during ensureing that axle box riser 26 is tightly attached on adjusting block 13.
In addition, adjusting block 13 is in length phase of the length perpendicular to 200 length direction of vehicle frame with fixture block 12 in this direction
Together.Specifically, adjusting block 13 is string configuration, simple in structure when length is consistent with fixture block 12, easy to implement.Optionally,
Adjusting block 13 is on 200 length direction of vehicle frame, or two strip arrangements separated by a distance, it is each to adjust
13 length of block is all higher than the length of axle box riser 26, in order to which axle box riser 26 is close to adjusting block 13 and is welded, this
Kind setting, under the premise of 13 function of adjusting block is ensured, volume reduces, and saves material.
Optionally, it is both provided with adjusting block 13 on the two sides towards 25 lateral margin of axle box square hole of fixture block 12.It should be evident that
Due to being required to welding axle box riser 26 on the lateral margin of 25 both sides of axle box square hole, adjusting block is respectively provided on the two sides of fixture block 12
13 so that the symmetrical configuration of positioning component 11, group to tooling 100 in actual use, the central shaft of positioning component 11 with
Front axle 23 and rear axle 24 where axle box square hole 25 overlap, and can improve the assembling precision of axle box square hole 25.
Axle box riser is close to positioning component weldering by the group of industrial-mineral electric locomotive axle box square hole provided in this embodiment to tooling
It connects, ensure that the assembling precision of axle box square hole, so as to ensure that the two axis depth of parallelisms of industrial-mineral electric locomotive EEF bogie, avoid wheel pair
With the generation of the serious safeties accident such as brake fade caused by brake shoe partial wear and vehicle derailing, the quality of vehicle release ensure that.
The size of positioning component can be changed by changing adjusting block, meet the group of different automobile types and axle box square hole size to requiring, be applicable in
Range is wide.Meanwhile the setting of fixture block and adjusting block size has fully considered that the size of axle box square hole and axle box riser and position are closed
System, it is ensured that the stability and accuracy of axle box riser welding.
