Description
Technical field
The present invention relates to a kind of upset fetal membrane for making box beam, particularly relates to make railway engineering rail vehicle bottom
The special overturning tire film of frame box beam.
Background technology
When making railway engineering chassis of rail vehicle box beam at present, railway engineering floor underframe for vehicle box beam match-place welding system
During work, it is ensured that all weld seams use downhand weld, and prevent box beam from being deformed because of welding；Box beam is made at present
When be on an opposed flattened platform, the fixture such as clamp with jack and arcuate and positioned, again positioning after downhand welding one side
Solder joint polishes off, and then box beam upset another side spot welding is fixed to carrying out downhand welding with driving, welding successively finishes.This kind of operation
Method labor intensity is big, and operating efficiency is low, and welding deformation is uncontrollable.
The content of the invention
The purpose of the present invention is to be directed to above-mentioned deficiency, and propose it is a kind of it is easy to use, efficiency is high, positioning precision
It is high, it is ensured that a kind of upset fetal membrane for making railway engineering chassis of rail vehicle box beam of product quality.
The present invention technical solution be：Job platform is fixed in the fixing axle of switching mechanism, and the two of the fixing axle
End is connected on support frame by bearing, and retaining mechanism is provided with job platform, and the limit of job platform is provided with support frame
Position mechanism.
Retaining mechanism described in the technical solution of the present invention is made up of bolt and lock bracket, and lock bracket is in
One H-shaped, three bolts are threadedly attached in the both sides perpendicular support and middle transverse bracket of the lock bracket of H-shaped respectively, lock
The lower end of locking bracket is welded on job platform.
Position-limit mechanism described in the technical solution of the present invention is fixed block and the weldering by being welded on job platform
The limited block being connected on support frame is formed, and the limited block on fixed block and support frame on job platform is symmetrical arranged.
Job platform described in the technical solution of the present invention is provided with backing plate.
The job platform of the present invention is fixed on support frame using switching mechanism and position-limit mechanism, upset fetal membrane is existed
Space 180 ° of any angles upset, and carried out by position-limit mechanism spacing, it is flat to ensure that box beam is taken all the time in welding process
Weldering mode, retaining mechanism locked to workpiece progress can prevent workpiece welding deformation；The present invention had both alleviated the work of operator
Intensity, operating efficiency is improved, in turn ensure that welding quality.
Brief description of the drawings
Fig. 1 is the structural representation of the present invention.
Fig. 2 is Fig. 1 A-A schematic diagrames.
Embodiment
As shown in Figure 1, 2, upset fetal membrane of the invention includes support frame 1 and the job platform 2 being located on support frame 1, branch
Support 1 is made up of two supports being parallel to each other, and the both ends of job platform 2 are connected to support frame 1 by switching mechanism 3 respectively
Two supports on, switching mechanism 3 is by fixing axle and is connected to the bearing of fixed both ends of the shaft and forms, and job platform 2, which is fixed on, to be turned over
In the fixing axle of rotation mechanism 3, the both ends of the fixing axle are connected on two supports of support frame 1 by bearing, operation horizontal
Platform 2 can be overturn at any angle in the range of 180 °；Retaining mechanism 4 is fixed with job platform 2, passes through retaining mechanism
4 can be locked on job platform 2 by box beam 6, prevents from deforming when welding box beam 6, and retaining mechanism 4 has multigroup, locking
The several length according to box beam 6 of group of mechanism 4 determine that retaining mechanism 4 is uniformly located on job platform 2, and retaining mechanism 4 is by spiral shell
Bolt 7 and lock bracket 8 form, and lock bracket 8 is in a H-shaped, and three bolts 7 are threadedly attached in H-shaped lock bracket 8 respectively
Both sides perpendicular support and middle transverse bracket on, the lower end of lock bracket 8 is welded on job platform 2, by lock bracket 8
Three bolts 7 can be locked on job platform 2 by box beam 6；Position restrainer is respectively fixed with two supports of support frame 1
Structure 5, position-limit mechanism 5 are made up of the fixed block being welded on job platform 2 and the limited block being welded on support frame 1, operation
The limited block on fixed block and support frame 1 on platform 2 is symmetrically located at, to make all position while weldings be in downhand weld position
Put, it is necessary to which Working mechanism turn over turning 90 degrees, fixed block after job platform 2, which turns over, to be turn 90 degrees thereon just falls in support frame
On limited block on 1.Backing plate is provided with job platform 2, backing plate uses t12, Q345B material, in use, under box beam 6
Plane is developed with backing plate.
Operation principle：The process of box beam 6, before use, checking the backing plate on present invention upset fetal membrane job platform 2
Flatness, backing plate flatness are not more than 1mm；Then the lower cover of box beam 6 is centrally placed in the backing plate on job platform 2
On, the lower cover of box beam 6 is compressed with retaining mechanism 4, ensures that its straight rear spot welding is fixed；In the lower cover of box beam 6
The position line where transverse direction, longitudinal center's line position and gusset is marked on plate, by drawing by gusset solid point in drawn position
Put on line, and weld the weld seam between gusset and the lower cover of box beam 6；By left and right the riser cross central line and case of box beam 6
The cross central line of the lower cover of type beam 6 overlaps, and riser is close to lower cover, the gusset of box beam 6, and is pressed from both sides with retaining mechanism 4
Tightly, oppose intralamellar part carry out positioning welding, when welding the cross joint between internal gusset and riser, will upset fetal membrane overturn to
Cross joint can be become downhand weld and be welded by 90 °, and prevent it from rocking 2 spacing fixation of job platform with position-limit mechanism 4, be treated
Fixture is unclamped after workpiece cooling；The upper cover plate of box beam 6 is overlapped with the cross central line of box beam, and clamped with retaining mechanism 4
After welded；Fixture, the demoulding are unclamped after box beam 6 thoroughly cooling.
