Description
Technical field
It is particularly a kind of to be used for centering work the present invention relates to a kind of centering system and its aligning method for centering workpiece
The offline centering system and its aligning method of part, belong to machining technique field.
Background technology
High performance today is pursued in military aircraft, the update of product is increased, corresponding aeronautical manufacture pattern
For Multi-varieties and Small-batch Production, utilization rate of equipment and installations is low under this production model, and the normal production for having badly influenced product is handed over
Pay.The key for lifting machine tool utilization rate is to reduce equipment downtime, influences to navigate under Multi-varieties and Small-batch Production pattern
Hollow structure part processing efficiency in addition to lathe inherent characteristic, main is exactly parts fixation time.Lathe production firm is always
Since be directed to exploitation lathe miscellaneous function to reduce the parts fixation time, such as multi-station machine tool, rotary table, but multiplexing
What position lathe was brought simultaneously is the lifting of increase and the regular maintenance requirement of lathe input cost, and for substantial amounts of small quantities of
Single-piece work is difficult to embody its design value, can not solve the problems, such as flexible clamping between different parts, different lathes.
Traditional aerospace component digital control processing aligning method：Workpiece is placed in numerically controlled machine, by using lathe
Digital control system and the motion of X, Y, Z grating, technique adjustment is carried out with reference to dial gauge to workpiece linearity and flatness.Due to medium and small boat
The multi items of hollow structure part, small lot Flexible production pattern, need according to projected demand, in same a machine tool in process of production
The upper different parts of different type of machines of frequently changing are processed, and during part exchanging, lathe, which must stop, carries out centering dress
Folder prepares.Small structures part is different from large-sized structural parts simultaneously, and large-sized structural parts clamping needs to process a week after finishing, had
Even one month, therefore confronting parts clamping time, accounting process time for large aerospace structural member is low, and the part that changes the outfit is accounted for
It is not very prominent with matter of time；And the small structures part part cutting time is relatively short, cause part needs frequently to change the outfit, changing
Need to carry out substantial amounts of clamping preparation during dress part, the lathe shut-down stand-by period is long, current major part aeronautical product processing factory
The flat utilization rate of lathe only has 40% or so, and wherein lathe accounts for more than the 30% of net cycle time because of centering clamping stand-by period of stopping work,
The average part time that changes the outfit every time, for 1 hour or so, seriously restricts the performance of small structures number of packages control equipment processing ability.
The content of the invention
The goal of the invention of the present invention is：Looked for for above-mentioned problem there is provided a kind of for the offline of centering workpiece
Positive system and its aligning method, the present invention are practical reliable, and highly versatile is simple to operate, with higher application value, workpiece
The operation of centering clamping is carried out in offline centering system, without being carried out on platen, is effectively avoided because in machine
Centering clamping workpiece on bed and cause lathe stop work situation occur, improve lathe utilization ratio.
The technical solution adopted by the present invention is as follows：
A kind of offline centering system for centering workpiece, including base station, and be assemblied on base station for clamping workpiece extremely
Few 1 supporting plate, in addition at least one are used for the joint arm of workpiece centering, and for operating joint arm measure workpiece and display
The controller of measurement data, the controller is connected with joint arm.
During using the present invention, workpiece to be processed pre-sets the linearity reference and standard of flatness of technique centering.
Of course, if required, other kinds of benchmark can also be set.By work piece on supporting plate, joint is operated by controller
The comprehensive linearity and flatness for rotating freely measurement workpiece benchmark of arm, the position of workpiece is adjusted until work according to measurement data
The linearity of part（The now three-dimensional coordinate X of linearity reference（Or Y）Value is identical）And flatness（The now three-dimensional of standard of flatness
Coordinate Z values are identical）Machining demand is met, is then secured the workpiece against on supporting plate, that is, completes the centering positioning operation of workpiece, will
Workpiece after centering is transferred on lathe together with supporting plate carries out machining operation.Original is completed in offline centering system
Originally the centering operation on platen, centering operation is separated with lathe, that is, realizes the offline centering of workpiece.Effectively
Avoid because the centering clamping workpiece on platen and caused by lathe shut down situation occur, improve machine tool utilization rate.
Supporting plate has plurality of specifications according to demand, and each supporting plate is that the area for installing workpiece face varies, and specification is different.When compared with
When big workpiece carries out centering operation, the supporting plate of 1 larger specification is assembled on base station, can be carried out simultaneously using multiple joint arms
Centering operation, naturally it is also possible to only carry out centering operation using 1 joint arm.When multiple less workpiece carry out centering operation
When, while assembling 1 workpiece of clamping on multiple supporting plates compared with small dimension, each supporting plate on base station, carried out using 1 joint arm
Centering operation, to make full use of the present invention.The workpiece to be processed for intending the lathe of the different type or specification used can be at this
Workpiece is transferred to corresponding lathe together with supporting plate after the completion of progress centering operation, centering in the offline centering system of invention
Upper carry out machining operation so that versatility of the invention is stronger, and the scope of application is wider.
