Description
Technical field
The present invention relates to the assembly method of a kind of pillow pulling structure railway tank car tank body and pillow pulling, be specifically related to a kind of pillow pulling structure tank car steel structure of car body mounting technology field.
Background technology
As everyone knows; When pillow pulling structure tank car steel structure of car body is produced; Last procedure tank body and pillow pulling are formed assembling (being called for short the tank body completion), because tank body self accuracy of manufacture, if directly tank body is assembled with pillow pulling during the tank body completion then can't be satisfied group to gap≤2mm.The production initial stage is adopted manual Correction Method, the jar that repeatedly falls, and repair body bolster diaphragm progressively adopts angle grinding machine polishing at last, and the method for the manual repair of this employing is difficult to satisfy the requirement to the gap of draw beam belly cutting accuracy Ra50 and tank body group.
Along with the tank car development; The traditional-handwork Correction Method can't satisfy the production demand, adopts a kind of laser contour device, through gathering tank body and body bolster diaphragm position shape data; With tank body true form data; The cutting body bolster diaphragm, tank body and body bolster diaphragm group are to gap≤2mm and draw beam belly cutting accuracy Ra50 requirement during with the completion of assurance tank body.
Summary of the invention
The object of the present invention is to provide the assembly method of a kind of pillow pulling structure railway tank car tank body and pillow pulling; Solve the manual repair technology when pillow pulling structure tank car steel construction completes in the background technology; Production efficiency is low, the problem that labour intensity is big, and adapt to the needs that laser contour cuts.
Technical scheme of the present invention is: the assembly method step of pillow pulling structure railway tank car tank body of the present invention and pillow pulling is following:
1) makes the pillow pulling process conditions: draw beam and sleeper beam lower cover, body bolster diaphragm, bottom side rail composition, end carriage composition are assembled into a pillow pulling and two pillow pulling process conditions; Sleeper beam upper cover plate and tank body are connected into the tank body process conditions;
2) the pillow pulling process conditions with step 1) hangs in tank car steel structure of car body completion tire; Make the locating surface of draw beam cartridge face and this position of foetus closely connected; The longitudinal centre line center line alignment of a pillow pulling and two pillow pulling process conditions detects length between truck centers and sleeper beam position diagonal error, after above-mentioned technical parameter meets the demands; Clamp draw beam, guarantee draw beam cartridge face and the closely connected gap≤0.5mm of completion tire fetal membrane;
3) the tank body process conditions is hung in the positions, the position of foetus of a pillow pulling and the completion of two pillow pulling process conditions, place on the elevation type rolling wheel frame between a pillow pulling and two the pillow pulling process conditions, adjust the Down Highway and the draw beam central lines of tank body;
4) with tank body rise to body bolster diaphragm on arc tips distance highly locate for H=55mm ± 5mm; The laser probe of plasma cutting machines is moved to the original position of body bolster diaphragm one side; The curvilinear path that the laser scanning probe is gathered the tank body corresponding with the body bolster diaphragm arc tips; And give the controller of plasma cutting machines with the tank body curvilinear path, plasma cutting machines is according to tank body curvilinear path shape cutting body bolster diaphragm;
5) tank body and body bolster diaphragm assembly welding:
After the polishing of the body bolster diaphragm after the shape cutting, tank body is fallen on the body bolster diaphragm attachment weld of welding body bolster diaphragm and tank body;
6) assembling side pipe pillar and connection gusset.
Described step 2) measuring vehicle spacing and sleeper beam part diagonal error are specially in: the lateral shift A≤2mm of a draw beam center line and two draw beam longitudinal centre lines; Sleeper beam position diagonal poor | L1-L2|≤10mm, the distance of two sleeper beam cross central lines poor | L3-L4|≤8mm.
The Down Highway of described step 3) adjustment tank body overlaps with the draw beam longitudinal centre line; Be specially: with the handling of tank body process conditions to the elevation type rolling wheel frame; Open the turning rolls rotating mechanism; Adjustment tank body longitudinal center line position guarantees the line of centres of two sleeper beam upper cover plates on the tank body and the lateral shift≤10mm of pillow pulling longitudinal centre line.
The body bolster diaphragm polishing of described step 5) after to shape cutting requires the surface roughness precision after the polishing to reach Ra50, and body bolster diaphragm and tank body group are to gap error≤2mm.
Advantage of the present invention: manual work repeatedly fell jar, repaiies repeatedly the method for cutting body bolster diaphragm when the present invention adopted the laser contour cutting technique to substitute early stage tank body completion.Gather tank body true form data through laser probe, drive the disposable cutting body bolster diaphragm of plasma cutting machines, make the tank body completion satisfy the relevant art clause, thereby reduce labour intensity, enhance productivity, practice thrift manufacturing cost.
The present invention has realized that tank car steel construction completion realizes the laser contour cutting, guaranteeing draw beam belly and tank body group to gap≤2mm, and, the surface roughness precision after the cutting of draw beam web is Ra50, enhances productivity the reduction manufacturing cost thereby reach.
