Description
Technical field
It is especially a kind of facial contour for detecting part and the position degree in each hole the present invention relates to the technical field of cubing
Longitudinal beam of automobile frame assembly characterization processes.
Background technology
Vehicle frame is most important load bearing component in automobile, and longitudinal beam is one of vital part therein, so longeron is in vapour
Important carrying effect is played on car.Longeron is generally stamped to form with low alloy steel plate, and section configuration is generally groove profile, also has
Make Z-shaped or box equal section.Longitudinal beam of automobile frame assembly upper installing hole is numerous, and with multiple curved surfaces, therefore its
All directions have mounting hole and mounting surface, and its overall structure is considerably complicated, and the size for having required precision has a lot, Er Qieping
Face degree requirement is also high, so must carry out the size detection of various pieces to it after the completion of longitudinal beam of automobile frame assembly is produced.Mesh
Before, aborning because output is big, only longitudinal beam of automobile frame assembly is inspected by random samples, but, inspect the detection instrument for using by random samples
To the Polling one by one of each part to be checked on longitudinal beam of automobile frame assembly, such as mounting hole thereon just has up to tens,
Such a one is detected and extremely lose time, and sampling observation cannot guarantee that all of product all meets the requirements.In addition,
Due to measurement error in comparison process, the detection data measured by cubing also needs to trickle finishing, the complex process of its detection,
Cycle is long, and efficiency is low, and error is larger.
The content of the invention
The technical problems to be solved by the invention are to provide one kind and detect that accurate, efficiency high, error are small, so as to ensure follow-up
The characterization processes of the longitudinal beam of automobile frame assembly for assembling and using.

2) various detection instruments are got out, including for detecting the detection of the position degree in each detection hole on longitudinal beam of automobile frame assembly
Pin, only drift or dial gauge for detecting facial contour on longitudinal beam of automobile frame assembly and for detecting that longitudinal beam of automobile frame is total
Rule are differed from into the face of top Line contour degree；
3) whether before detection is started, testing staff need to carry out range estimation inspection to detection mould, to determine detection mould in available
State；
4) all of clipper and turning device are opened, whole secondary detection mould is in off working state；
5) longitudinal beam of automobile frame assembly is put into, it is close to A1 locating pieces, A2 locating pieces, A3 locating pieces and A4 locating pieces
On, and B alignment pins and C alignment pins are inserted, and adjustment position is suitably reinforced, close clipper, it is ensured that each locating surface and product
Product contact is good；Then close turning device, starts to detect product；
6) position degree detection is carried out to the hole position on longitudinal beam of automobile frame assembly using each test pin successively；If can be normal through product
Product, then product is qualified, otherwise is then unqualified；
7) respectively successively with gap between the part detection block on the only drift detection product of all size and each turning device come really
The facial contour of fixed output quota product, if go side can pass through, not-go-end can not pass through, and for product is qualified, otherwise be then unqualified；
8) centimeter check product type profile tolerance of a surface is used, first is zeroed for numerical value on to zero piece by dial gauge before detection, detected
When display data in the ± 0.5mm for qualified, otherwise then for unqualified；
9) sideline profile tolerance corresponding between rule detection simulated block and product is differed from face, if sideline is in the margin of tolerance, is considered as
Product is qualified, otherwise is then considered as unqualified；
10) all of clipper is opened after the completion of detecting, all test pins and alignment pin is extracted, all of turning device is opened,
Cubing is in off working state, longitudinal beam of automobile frame assembly can now be removed from detection mould；
11) to detect next product, then repeat the above steps；If detection is finished, off working state is placed into, and cover
Dust cover；
12) it is last, will detect that the longitudinal beam of automobile frame assembly for completing is placed on CMM the collection for carrying out product data.
