Abstract
The utility model provides a turnover frame technological equipment of aluminum alloy body large components for railway passenger, which is a device composed of a fixture body and a working support base; the fixture includes a longitudinal beam and a transverse beam. The two ends of the transverse beam are fixed with a longitudinal beam respectively; the side of the longitudinal beam is provided with a rib plate of T groove; the top device of the rib plate has a positioning pin shaft; the working support base includes a chassis and a support bracket; the fixture body forms a bridge structure through a positioning pin shaft frame of the two ends of the body at the working support base at two ends. The fixture body clamps firmly a large components and hoists one end of the fixture body through a hoisting seat and a hosting chain and turn over 180 degrees taking the working support base in the middle as an axes to joint with the working support base on the other end in order to perform 180 degrees turnover. One-time clamping method is used to complete two-face welding; the whole welding process of the components is subject to clamping controlled state, which is less deformation and predicable to promote the quality of large component production.
Description
Technical field
The utility model discloses the turning frame-type technological equipment of the big parts of a kind of passenger train aluminum alloy bodywork, belongs to frock jig device structure technical field.
Background technology
Along with improving constantly of passenger train speed, more and more adopt aluminum alloy materials to make passenger car body.Aluminum alloy bodywork has in light weight, and is corrosion-resistant, and the flat appearance degree is good and be easy to make the characteristics of complicated curved surface attractive in appearance.Because aluminum alloy bodywork has other material irreplaceable function in the high-speed railway vehicle manufacturing, therefore, countries in the world have begun to use in a large number aluminum alloy materials in passenger train production.
The aluminum alloy bodywork material is the big-and-middle-sized hollow extrudate isometric with vehicle body, adopts extrusion forming technology to make by aluminium section bar factory.The big parts of passenger car body (comprising side wall, underframe, roof) are to adopt two-sided continuous welding process to form by 5 to 9 blocks of such section bars.
Because the aluminium alloy fusing point is low, fusing is fast, and surface tension is little, and simultaneously, in the metal molten process, the molten bath does not have obvious color to change again, and therefore, the aluminium alloy welding is much more difficult than other metal solder.Good technological equipment is effective assurance of product quality.In the big parts group of aluminum alloy bodywork in, when welding, needed formal dress and the counter two cover frocks of adorning, finish double-edged welding respectively.Be the control welding deformation, original method is to finish positive the welding, could hang out from frock after workpiece cools off fully, and workpiece is put into the reverse side welding tooling after turning over turnback, and the location clamps laggard capable reverse side welding.Easily cause distortion because of workpiece needs the secondary clamping, the assembly welding quality is wayward.
Summary of the invention
The utility model provides the big parts of a kind of passenger train aluminum alloy bodywork turning frame-type technological equipment, purpose is intended to solve the problem of workpiece secondary clamping, change the secondary clamping into a clamping and finish the two sides welding, thereby effectively control welding deformation and enhance productivity.
Technical solution of the present utility model is as follows: constitute this device by clamp body and frock supporting seat, wherein, clamp body comprises longitudinal beam and transverse beam composition, two ends in transverse beam are fixed with longitudinal beam respectively, the side of longitudinal beam is provided with the gusset of T type groove, and the top device of gusset has alignment pin; The frock supporting seat comprises chassis and bearing support composition, and clamp body constitutes bridge architecture by the alignment pin pedestal at body two ends on the frock supporting seat at two ends.
The utility model in use, the parts different according to assembly welding, the location clamping element is installed in the transverse beam of clamp body clamps large-scale workpiece, side by clamp body play flap seat and chain sling, one end of clamp body is sling, frock supporting seat with the centre carries out 180 degree upsets as the axle center, rides on the frock supporting seat of the other end, finishes 180 degree upsets of big portion workpiece.
Good effect of the present utility model is: clamp body adopts frame clamp body overturn structure, is changed into once by the secondary clamping in past, avoided first postwelding that workpiece is hung out from frock after, workpiece is in free state, causes distortion.Adopt a clamping to finish the two sides welding method, workpiece is in the slave mode of clamping in whole welding process, and welding deformation is very little and measurable, has improved big parts workmanship.The temperature of workpiece being taken out workpiece such as need after the past one side welding from frock is reduced to room temperature, a big parts single face approximately needs 2 hours cool time, use the present invention and can after the one side welding is finished, carry out the welding of another side immediately, saved cool time, improved production efficiency.Save production site, reduced the frock input.Big parts assembly welding frock floor space is 30 meters long 4 meters wide, uses the present invention and past two cover frock can be merged into a cover, and a big parts frock can be saved 12 square metres of plant areas, reduces frock and drops into 400,000 yuan.
Description of drawings
Fig. 1 is the utility model structure principle chart.
The specific embodiment
According to shown in Figure 1, the tower structure that clamp body 1 is formed for rectangular steel pipe, comprise longitudinal beam 4 and transverse beam 3 compositions, longitudinal beam 4 is fixed on the two ends of transverse beam 3, the rectangular steel pipe specification is 360 * 200 * 10, the gusset 5 that is processed with T type groove is installed in side at longitudinal beam 4, and the top device of gusset 5 has alignment pin 6; Frock supporting seat 2 comprises chassis 7 and bearing support 8 compositions, and clamp body 1 constitutes bridge architecture by 6 of the alignment pin at body two ends on frock supporting seat 2.The parts different according to assembly welding are installed the location clamping element on clamp body.
