Description
Technical field
The present invention relates to a kind of splicing assembly tooling of standard EMUs composite underbody equipment compartment crossbeam.
Background technology
Bullet train is the important technical achievement of world's railway, and it is dynamic that it has embodied a concentrated reflection of a state-owned railroads traction
Technological progress in terms of power, line construction, high-speed cruising control, rapid transit tissue and management, also embodies one
National science and technology and industrial level.Train is a kind of independent body structure, can provide good under the conditions of severe external environment
Good internal work environment, with a variety of protective capacities and mobility is good.But prepared more than existing car body using metal material, machine
Dynamic performance is not good and requires higher energy consumption, and high using specific strength, specific modulus is big, and anti-fatigue performance is good, and chemical resistance is good
The advantages of carbon fibre composite can effectively improve the combination property of car body, particularly mobility.
Crossbeam is one of important composition part of equipment compartment, and the equipment compartment crossbeam used at present is generally metal material, due to
Metal material density is big, is unfavorable for the raising of car body loss of weight and overall performance.The carbon of equipment compartment crossbeam has been may be used as at present
The manufacture method of fibrous composite beam, but because the post-production and assembly technology of composite are more difficult, be not suitable for
Ensure the final assembly precision of crossbeam, and product qualification rate is relatively low.
Above mentioned problem should be given in the production of standard EMUs composite underbody equipment compartment crossbeam and assembling process
The problem of to consider and solve.
The content of the invention
It is an object of the invention to provide a kind of corresponding splicing assembly tooling of EMUs composite underbody equipment compartment crossbeam,
It is as follows for solving defect present in prior art and deficiency：Conventional adhesive bonding of composites technique is bonding by hand, it is impossible to full
The quality requirement of sufficient high standard, while production efficiency is low, it is larger to use of labor, and it cannot be guaranteed that the precision being glued, and
And product percent defective is higher, the production cost of composite crossbeam is considerably increased.
The present invention technical solution be：
A kind of splicing assembly tooling of standard EMUs composite underbody equipment compartment crossbeam, including base platform, web
It is glued component and covering is glued component, web is glued component and covering is glued component and is respectively arranged in base platform；
Web is glued component and is glued component using detachable web, and web, which is glued component, includes some portal frames, rectangle
Guan Yi, rectangular tube two, straight pin, side screw, top screw, the both sides of portal frame are connected to pedestal by straight pin respectively and put down
On platform, the top of portal frame, which is provided with, to be used to apply rectangular tube one on stressed top screw, and the both sides of portal frame are respectively equipped with use
In applying stressed side screw to rectangular tube two, rectangular tube one, rectangular tube two are sequentially arranged between portal frame and base platform；
Covering be glued component using detachable covering be glued component, covering be glued component include some pipes, square tube one,
Square tube two for fixed cross beam, some it is used to apply square tube two stressed fast ram pressure, some pressure head cushion blocks, base platform
Both sides be respectively equipped with pipe, square tube is vertically connected on pipe by retaining screw, and the both sides of base platform are respectively equipped with two
Pressure head cushion block more than individual, pressure head cushion block is respectively equipped with fast ram pressure, and the both sides of base platform are respectively equipped with square tube two.
Further, base platform is provided with length limited block.
Further, base platform is provided with Universal rotary suspension ring.
Further, using the specific of base platform, web splicing component progress cantilever diaphragm and the splicing of web reinforcing plate
Step is：Uniform apply is spread after structure glue on the splicing face of cantilever diaphragm, and cantilever diaphragm is steadily positioned in base platform,
Two rectangular tubes two are individually positioned in the non-splicing face for lying against cantilever diaphragm；Then will be equal on the splicing face of web reinforcing plate
Even painting is spread after structure glue, and web reinforcing plate is fitted in the splicing face of cantilever diaphragm, and rectangular tube one is lain against into web strengthens
The non-splicing face of plate, the purpose that the side screw of portal frame, top screw reach clamping force is tightened by rotation, is stood and is extremely tied
After structure adhesive curing, dismounting web is glued the crossbeam semi-finished product that component has been glued.
Further, it is glued component using base platform, covering and carries out the specific steps that lower covering, upper covering are glued respectively
It is：On the splicing face of covering after uniform smearing structure glue, lower covering will be steadily positioned in splicing frock under crossbeam, and glue
The lower surface of the crossbeam semi-finished product connect is fitted with the splicing face of lower covering, and square tube two is lain against to the crossbeam semi-finished product that have been glued
Non- splicing face；Then it is uniform on the splicing face of covering on crossbeam to apply the crossbeam semi-finished product for spreading and being fitted in and being glued after structure glue
Upper surface on, clamping force is realized by square tube one and fast ram pressure, stands to structure adhesive curing i.e. detachable, is obtained
The crossbeam finished product of splicing.
The splicing assembly tooling of this kind of standard EMUs composite underbody equipment compartment crossbeam, including base platform and abdomen
Plate is glued frock and covering is glued frock, and two sets of frocks are with after base combination, being respectively used to crossbeam or so web and covering up and down
