Description

A kind of type frame for airline carriers of passengers kitchen Standard

Technical field

This utility model is related to a kind of assembly jig, especially a kind of type frame for airline carriers of passengers kitchen Standard.

Background technology

Airline carriers of passengers generally needs 2～3 sets of kitchens of configuration, for providing the diet food and drink of passenger during the journey, large-scale expanded letter Passenger plane will be more to the demand in kitchen.Due to the hard requirement to aircarrier aircraft safety, comfortableness, the work in airline carriers of passengers kitchen Skill manufacture method has larger difference with traditional vehicle-mounted cupboard, boat-carrying kitchen.The kitchen of airline carriers of passengers is generally by lightweight, high-strength, height Fire-retardant, low toxicity material is made, usually honeycomb sandwich structure, foam sandwich construction etc..Due to the particularity of material, kitchen is each The assembling of part is compared common parts assembling and is very different, and difference is embodied in：Reference for assembling difference, build-up tolerance are coordinated, dress With connected mode etc..

At present, the assembling in aircarrier aircraft kitchen mainly adopts hand assembled, or using easy assembly tooling as auxiliary Help.But with regard to two methods, preferable effect is all extremely difficult to precision, efficiency for assembling etc..It is specific as follows：1. each component in kitchen Between positioning it is difficult；2. the control such as the overall dimensions in pair kitchen, form and position tolerance is more difficult；3. the efficiency of assembling in kitchen is low.4. use Life-span is not high.

Utility model content

The technical problems to be solved in the utility model is：Based on the problems referred to above, there is provided one kind is solved for airline carriers of passengers A difficult problem for form and position tolerance, positioning and assembly connection between each component in kitchen, can be fast and accurate same to each component multilamellar in kitchen The type frame of Shi Jinhang assemblings positioning and the Standard of fastening sizing.

This utility model solves the technical scheme that its technical problem adopted：It is a kind of to fill for airline carriers of passengers kitchen structure The type frame matched somebody with somebody, including base and type frame housing, the type frame housing is fixed on base, and the base has underframe, the bottom Frame is provided below spiral lift device, and on the top of the type frame housing, bottom and two sides upper limit is respectively arranged with Device, bottom limiting device and side limit device, are evenly distributed with even number laser seat on the column of type frame housing front end face Calibration on schedule, is horizontally arranged with least one and consolidates at the position between the correspondence laser coordinate check point of type frame housing front and rear end Determine blend stop bracket, on fixed blend stop carriage inner lateral some evacuating pus and expelling toxin framves are fixed with.

Even number laser coordinate check point is the anchor point of laser locator correction type rack position, is conveniently adjusted overall type frame Put vertical level；Fixed gear bar bracket makees that Y-direction is fixed, spacing clamping device, limits single kitchen constitutional detail interlayer Y side To position；Row's bracket support kitchen part, limits the form and position tolerance and flatness and perpendicularity of single part；Left and right side is spacing Device, limits side and stands to single kitchen constitutional detail X-direction position；Upper limit device, limits the single kitchen structure in side Part Y, Z-direction position, the upper and lower play of limit feature；Bottom limiting device, limits side and stands to single kitchen constitutional detail Y, Z Direction position, while controlling overall Assembly part overall height dimension.So both can guarantee that locus were fixed, be that follow-up riveting is established Determine stability fundamental.Effective overall dimensions, form and position tolerance to kitchen etc. is controlled, and guarantees the concordance of product.

Further, the cross section of the side limit device is L-shaped, and by alignment pin and is bolted to column On, the corner of side limit device has assembling empty avoiding groove.The corner of side limit device has assembling empty avoiding groove, Facilitate corner Edge-protecting section bar position to finely tune up and down, enable corner Edge-protecting section bar that riveting dress is disposably completed in assembling process Match somebody with somebody, reduce turn around time, saved production cost.

Further, the two ends lower section that the underframe has two parallel connection section bars, connection section bar is fixed with spiral Lowering or hoisting gear, the spiral lift device specifically includes support adjusting nut.

Further, each angle of the type frame housing is provided with cornerite.

The beneficial effects of the utility model are：

1) ensure accuracy and the exchange of product, and ensure to enter accurate positioning when the part of assembling, plate are assembled, keep Its precise shapes and certain process rigidity, to be attached.

Compared with other fixtures, in addition to playing positioning and acting on Clamp blocks, it is ensured that product design it is accurate：Civil aviaton The quantity of the type frame positioning original paper of passenger plane kitchen Standard suitably increases according to the rigidity for calculating assembly parts, there is certain excessively fixed Position；Secondly, different degrees of deformation can be all produced in this connection, this aircraft honeycomb synthesis spare part assembly tooling can be limited This deformation of workpiece；3rd, it is mutually coordinated with the technological equipment of product in batch production, so aircraft honeycomb is closed Complete property and harmony into spare part assembly tooling is a distinguishing feature；

2) improve working conditions, improve assembly work production efficiency, reduce production assembly cost.

Because the type frame positioning and clamping of airline carriers of passengers kitchen of the present utility model Standard considers complex so that produce The less weakness of product detail rigidity intensity, adopts this assembly tooling in assembling process, just can more play fixture positioning and clamp Rapid reliable effect, lifts the work efficiency of assembling.

3) suitability is extensive, extensively using Assembling Productions such as aviation, light rail transits.Assembling steady quality, maintenance cost is low, The advantages of long service life.
