Description
Technical field
The present invention relates to a kind of processing tool, particularly to a kind of processing work for processing EMU car body skirtboard
Dress, belongs to EMU car body processing tool technical field.
Background technology
Most of key equipment of EMU is lifted under car, EMUs on the line high-speed cruising when can produce very
Strong air pressure wave, therefore sandstone, ice cube or other objects and car are divided into the raw fortuitous event hitting at a high speed of preparation and are often sent out
Raw, seriously jeopardize the application safety of bullet train.For reducing air drag, under protection and tool car, equipment is it is ensured that high speed motor car
The safe operation of group, it is necessary to design and installation have leads under the car of the EMU of speed per hour 200 km and above speed class
Equipment compartment under stream, the totally-enclosed car protecting, overhauling function, under car, equipment is arranged in equipment compartment；Equipment compartment is mainly by skeleton, bottom
The skirtboard of plate, the end plate at two ends and both sides surrounds, generally box-shaped full-closed structure, is carried using frame-type skeleton.According to it
The difference of function, equipment compartment apron board is divided into air draft, air intake, sliding window, hermetically sealed 4 classes again.Air draft skirtboard is provided with discharge window, air intake
Skirtboard is provided with filter screen and labyrinth structure, and sliding window skirtboard is mainly used in water tank and adds water.Skirtboard is distributed in equipment compartment both sides, bottom in arcuation
Portion is connected to skeleton side bar through arc hook, and upper end is secured by bolts in car body side bar, in order to installing and overhauling.Therefore skirt
Plate is the critical component of equipment compartment under motor train unit, covers car using the skirtboard matching with vehicle body transverse shape and divides into
Standby, provide lateral protection for hanging device under car, both can reduce air drag, and hit prevented also from the sandstone that high-speed cruising brings
Call a taxi lower equipment, using skirtboard, the equipment of the car bottom under high-speed travel state can be protected, the installation of skirtboard
Cheng Shi, first processes connecting hole on skirtboard, then skirtboard is fixed in the pre-drilled hole of car body.
Existing high speed motor car equipment compartment aluminum alloy apron board is made up of machining to rear welding of 7.4 meters of section bar groups again,
Because skirtboard profile size is larger, relatively thin, poor rigidity, complex-shaped and irregular, it is also easy to produce in clamping process and the course of processing
Deformation, proposes higher requirement to process equipment, processing technique, frock, and its processing characteristic is, and 1, need large-scale processing to set
Standby, typically adopt gantry machining center in prior art；2nd, due to skirtboard shape not a flat board it is impossible to directly set in processing
Process on standby work platformses, therefore, fixed skirt need to be carried out by frock.
The common positioning clamping mode adopting in prior art, working (machining) efficiency is relatively low, and clamping leads to positioning precision repeatedly
Not high, man-hour consuming is many, and the effect controlling section bar deformation in the course of processing is not fine, and skirtboard deformation after leading to processing surpasses
It is difficult to ensure the dimensional accuracy of skirtboard after machining, crudy is greatly affected difference.Additionally, the processing of prior art
Its modulability of frock is poor it is also difficult to the clamping adapting to multiple skirtboards uses it is impossible to meet the dissimilar skirtboard of secondary process
Require, have the little limitation of the scope of application.EMU vehicle vehicle is numerous at present, and streamlined appearance design is in variation
Trend, car body is streamlined to be mainly reflected on side wall, and side wall of aluminum alloy bodywork is big as EMU appearance requirement highest
Part, often carries out personalized, differential design in design, and skirtboard needs to match with car body transverse shape, therefore leads
Cause skirtboard in EMU vehicle often product category various, disparity items differs greatly, during processing just
Can there is frock difference big, the feature of poor universality.
For this reason, it may be necessary to develop the general processing work providing the EMU car body skirtboard processing that can eliminate drawbacks described above
Dress.

The processing tool of EMU car body skirtboard described in a kind of 14. utilization claim 1～13 any one claim
Processing EMU car body skirtboard method it is characterised in that：Comprise the following steps：
A) before placing skirtboard, according to the relative dimensions of its structure of skirtboard, first adjust the sliding table corresponding to skirtboard two ends
Position；
B) and then so that remaining sliding table is distributed between skirtboard two ends, it is fixed and with U-shaped grip block, sliding table to be carried out
Position；
C) adjust the distance between sliding seat and fixed seat again, so adjust prelocalization plate, lateral register plate and rear position plate it
Between relative position；
D) it is connected to the upper end of each support base according to the cushion block that the radian of skirtboard chooses proper height, and adjusts support base and sliding
The position started building in station；
E) place skirtboard, supported the side of the every side of skirtboard by prelocalization plate and rear position plate respectively simultaneously, and adjust skirtboard
Position so that its front side edge is leaned against on lateral register plate；
F) last, it is arranged at fixed seat, first corner cylinder at sliding seat top, the second corner cylinder compress to skirtboard respectively
（First corner cylinder is prior to the second corner cylinder action）, processed skirtboard is gradually pushed to lateral register plate, realizes lateral register；
G) start drilling-milling apparatus and complete the processing to connecting hole on processed skirtboard；
H) the first corner cylinder, the second corner cylinder unclamp the compression to skirtboard, the artificial skirtboard taking out completion of processing；
I) repeat above a～l step operation, carry out the processing of next skirtboard.
