In the process of actual automobile engine nacelle welding assembly, realized using this automobile cabin detection tool Multiple engineering steps: step 1, first by enging cabin at the side fine strain of millet sub-unit LH, enging cabin the fine strain of millet side sub-unit RH and antetheca Web beam places the predetermined position for being located in cubing and realizes that assembling is fixed and forms enging cabin front end under plate;Step 2, will Obtained enging cabin front end and front anti-collision beam placement in step 1 navigate to predetermined position and realize that assembling is fixed and is formed and is sent out Motivation cabin front end sub-unit;Step 3, the obtained enging cabin front end sub-unit in step 2 is placed with front panel sub-unit It navigates to predetermined position and realizes that assembling is fixed and forms enging cabin welding assembly.Above-mentioned steps are by corresponding in cubing Installation position and each assembling module is spliced to form, this cubing can realize the location-independent and detection of each one-piece part, two The cooperation inspection of two parts, and the riveting according to process flow chart (Flowchart) simulation spot welding mode from single-piece to assembly, It needs that enough assembly manipulation spaces and riveting operation space, that is, this cubing set is stayed to measure bracket, riveting branch from design Frame, single-piece detection and localization, the functions such as assembly detection and localization.The design of cubing is from actual workability, safety, human engineering etc. Aspect comprehensively considers.To a person skilled in the art, on the basis of cubing modular system disclosed by the utility model, Using various above-mentioned positioning and the combination of testing agency to realize that it is practical that the technical solution of above-mentioned engineering step should be included in Within novel protection scope.
The utility model can realize the location-independent of each unit part, two-by-two the cooperation inspection of part, and according to technique Flowchart Simulation is spot welded riveting of the mode from single-piece to assembly, needs to stay enough assembly manipulation spaces and riveting empty from design Between.And realize the sheet of specified level and the location-independent of assembly, the part two-by-two of any logical relation side by side can position simultaneously In cubing, realize that cooperation checks.
For convenient for intuitively comparing using with real vehicle, the positioning coordinate of cubing and the positioning coordinate of real vehicle are consistent.Vehicle Cubing is consistent with real vehicle at covering assembly with the anchor point of trim assembly.Most cubing setting all with vehicle sheet metal component one Sample is set with major and minor two location holes.Master positioning pin is straight pin, and secondary location hole is link pin, to limit workpiece in Z, X, Y, Z-direction Freedom degree.The active module of the utility model can be switched fast, and can guarantee that benchmark is correct, and the positioning of dismounting uses specification one The bolt of cause.Later period easy to use replaces in time, maintenance.
To prevent the downslide of active unit block from causing safety accident, rotation/sliding cell block, be provided in place (starting and Stop position) limitation bolt or block.Ergonomics is considered when design, the cell block of all disassemblies is no more than 6KG.For Some unavoidable module designs corresponding power-assisted and buffer gear.All 1anding profiles, which exist, interferes possible position all to exist Quantifiable testing agency of giving up the throne is set in interference surface normal orientation.Positioning pin, positioning are installed by guaranteeing after fastening parts Face can be unloaded.It avoids because part and workpiece zero paste clamping stagnation in use process, error caused by caused workpiece interference deformation, and The problems such as reality rivets when need to not enough remove because of working space, can not be successfully dismounting.
All location holes relevant to component assembly and pilot hole are designed using insert.Rigidity, the intensity of insert are met Repeated disassembled and assembled requirement.Insert is designed to quick-replaceable, and the re-calibration of three coordinates is not required to after dismounting.That is positioning surface surface 3mm's Cure process, surface hardness also guarantee in Rockwell 50-55 degree or so.Pin surfaces cure process, Rockwell hardness guarantee 55-58 Degree.All loose mails are connected near installation point using wirerope.Any dismountable component is labelled, and subregion keeping is being expected On frame, to prevent loss of parts.
When the positioning surface or faying surface of cubing are zero junctions, the rearward position that 3mm is differed with theoretical position is all set, And guarantee arbitrarily to adjust in this 3mm, and adjusting gasket is arranged at rear, it is convenient for the problem of analyzing part.All main support faces It is all equipped with clamping function, some supporting surfaces for being difficult to realize clamping function are used with the principle of strong magnet absorption, reaches clamping Effect.Detection for hole uses in the design of cubing and sets detection hole on axis of workpiece uniform location, usually detects The big 4mm in hole aperture ratio workpiece aperture.After the part having good positioning is compressed with pressing tongs, reticle pin is inserted into from detection hole, in workpiece Circle is drawn on surface, checks whether the center of circle of drawn circle is consistent with part, determines the position degree in general hole in this way.When measured hole essence Feeler gauge or bushing is then used to detect when spending more demanding.
In order to overcome single detection structure defect, realize that the departure of product is controllably surveyed by regulating mechanism and gasket Amount, by the sheet metal component before batch production, all control improves finished product accuracy in tolerance permitted range after riveting with assembly, leads to After the data creating that point inspection for several times obtains at table.
The above descriptions are merely preferred embodiments of the present invention, is not intended to limit the utility model, for this For the technical staff in field, various modifications and changes may be made to the present invention.It is all in the spirit and principles of the utility model Within, made any modification, equivalent replacement and improvement etc. should be included within the scope of protection of this utility model.
