The specific embodiment
Below in conjunction with the accompanying drawing and the specific embodiment the utility model is described in further detail:
As shown in Figure 1 to Figure 3, the bogie frame of rail vehicle bottom includes two curb girders 1, two crossbeams 2 and is arranged on four journal box spring seats 3 of two curb girder 1 ends.
Arrive shown in Figure 4 as Fig. 1, rail vehicle framework processing tool described in the utility model when the processing framework, is placed on the framework process equipment workbench (not shown), frock includes pedestal, hold down gag 8, side ejection device 9, auxiliary support apparatus 10, positioner.
Wherein, pedestal includes base plate 4, and base plate 4 adopts the thick steel plate of 50mm, can play stronger carrying effect.Be fixed with four bases 5 on base plate 4, the below of each journal box spring seat 3 all is provided with a base 5, and above-mentioned hold down gag 8, side ejection device 9, auxiliary support apparatus 10 all are fixed on the base 5.A plurality of reinforcements 6 are set on base plate 4, are bolted to connection between reinforcement 6 and the base plate 4, reinforcement 6 can improve the intensity of whole frock, the problem on deformation in effectively preventing to use.
The last lower plane of base plate 4 is all processed smooth, with on the contact-making surface of framework process equipment workbench three positioning key (not shown)s are set, positioning key is corresponding with the locating slot on the workbench, like this, when frock is placed on workbench, can be placed directly in suitable position, no longer need centering repeatedly by positioning key, save the working time, also reduced labor intensity of operating personnel.
When the framework that need process is placed on this frock, dependence positioner location, positioner is the alignment pin 7 that is fixed on the base 5, and as locating hole, each locating hole is equipped with an alignment pin 7 to this frock with two journal box spring holes on the existing side curb girder 1.Because the quality of fit of alignment pin 7 and locating hole is higher, if two alignment pins all adopt round pin structure location, will be very difficult when placing framework, in the present embodiment, as shown in Figure 5, two alignment pins 7 have adopted a round pin structure and a cotter pilotage structure Design for this reason, like this, when placement positioning pin 7, the round edge of cotter pilotage is placed on the direction vertical with curb girder 1, just can comparatively easily framework be placed on the frock.
After framework is placed on the frock, need compress framework in vertical direction, so that the processing of framework, present embodiment adopts hydraulic compressing device 8 workpiece pressing in vertical direction, each journal box spring seat 3 place respectively is provided with a hold down gag 8, so be provided with four hold down gags 8 altogether.
Hold down gag 8 adopts presser arm 13 rotatable rotary hydraulic cylinders, is connected with Hydraulic Station 11 by hydraulic line, provides constant compression force to compress by Hydraulic Station 11, and presser arm 13 can be rotated in 105 degree, is convenient to the installation of framework.
In order to make framework that the skew of direction all around not take place on frock, need increase side ejection device 9 and auxiliary support apparatus 10 to frock, framework is reinforced.
Wherein, side ejection device 9 is placed on the both sides of journal box spring seat 3, is used for clamping from both sides in the horizontal direction framework, each framework has four journal box spring seats 3, so eight side ejection devices 9 need be set altogether, side ejection device 9 adopts hydraulic cylinder, is connected with Hydraulic Station 11 by hydraulic line.Framework is placed the back and is carried out the fixing of constant pressure by hydraulic system, guarantees that framework is stressed evenly, thereby guarantees the stability of framework processing.

The below at two curb girder 1 centers of framework is respectively arranged with second auxiliary support apparatus 12 again, second auxiliary support apparatus 12 adopts hydraulic cylinder too, is connected with Hydraulic Station 11 by hydraulic line, framework is played the effect of further support, make framework stressed more even, prevent the framework distortion.
In this frock, when compressing and supporting, Hydraulic Station 11 provides the pressure of constant pressure, general pressure is 5-6Mpa, and compress and unclamp whole employing hydraulic controls, and voltage supply and pressure release adopt two circuits systems, and using system work is more reliable and stable.
All adopt snap joint to be connected between hydraulic line and the Hydraulic Station 11, operate more simple and convenient.
Hydraulic line is provided with the pressure switch (not shown), in process, if when occurring hydraulic system because of leakage of oil, step-down; the pressure switch action, and report to the police, accumulator is given the hydraulic system fuel feeding immediately simultaneously; make the system pressure protection stable, thereby guarantee the stability of workpiece.At this moment, should stop processing immediately, carry out the maintenance of hydraulic system.
The course of work of this frock is as follows:
1, framework and frock placement plane are cleared up.
2, frock is placed on the workbench of framework.
3, use overhead traveling crane to hang, aim at the positioner of framework, framework steadily is placed on the frock.
4, each hydraulic line is connected with Hydraulic Station 11 by snap joint.
5, press " compressing " button, Hydraulic Station 11 begins to each hydraulic system voltage supply, compress and supporting frame, this moment Hydraulic Station 11 pressure is provided is 5-6MPa.
6, when reaching pressure, Hydraulic Station 11 fuel cut-offs utilize snap joint that Hydraulic Station 11 is separated with workpiece, carry out the processing of framework.
7, machine after, reconnect hydraulic line and Hydraulic Station 11, by " unclamping " button, Hydraulic Station 11 begins to the pressure release of frock hydraulic system, after framework is unclamped, transfers framework.
As mentioned above, given in conjunction with the accompanying drawings scheme content can derive the similar techniques scheme.In every case be the content that does not break away from technical solutions of the utility model, to any simple modification, equivalent variations and modification that above embodiment did, all still belong in the scope of technical solutions of the utility model according to technical spirit of the present utility model.
