Description
Technical field:
The present invention relates to the fields of measurement of thin plate, relate in particular to the detection method of pressed sheet.
Background technology:
At present, for the punching type magnet that motor or generator and scientific research are used, the shape and size of punching are the results through large-scale finite element analysis software repeated calculation, must guarantee the shape and size that calculating gets in the process of magnetic cell manufacturing.During manufacturing, after the punching out of finishing first punching, to carry out the size detection of three coordinates usually, check whether the cartridge part of magnetic cell satisfies designing requirement, have or not local defect or influence the flaw of magnetic cell performance.If pinpoint the problems, then need repair is carried out in diel, and then try to dash, the punching of punching out detects again, detects so repeatedly and repair, could begin punching out production in batches after test passes.In the process of producing, after the punching of every punching out some, also need the sampling Detection punching, see in process of production, thereby whether diel produces the quality that distortion or chipping have had influence on the production punching.
It is vital production link that punching detects for the enterprise that specializes in motor production, and the three dimension coordinate measurement equipment that enterprise can be equipped with specialty according to the shape and the characteristics of own product is monitored the link of being produced.Use traditional three-coordinates measuring machine, owing to the instrument reason need be propped certain altitude with punching, it is sagging to produce nature for large-scale punching meeting, has brought relative measuring error; The metering system of three-coordinates measuring machine is surveyed for single contact point, and measurement result is the position coordinates of each measuring point, for the punching of complicated shape or the punching that has profile tolerance to require, reflected measurement result intuitively.And for R﹠D institution, often do not have this type of checkout equipment, and can only rely on external coordination producer, detect the control of guaranteeing quality by the enterprise that this type of checkout equipment is arranged.And the three dimension coordinate measurement equipment of enterprise normally is equipped with at the product of this enterprise, and the punching that does not meet this enterprise product for size and profile just can not detect.If the checkout equipment of being entrusted is in the strange land, the process of transportation also can cause the punching distortion, makes testing result lose meaning; Simultaneously, such transportation repeatedly detects and also to make the production run wait testing result that is deadlocked, and can not accomplish to monitor constantly, makes production cycle and cost sharply increase.
Summary of the invention:
The objective of the invention is to avoid the deficiencies in the prior art, a kind of punching detection method and detection measuring seat thereof are provided.The present invention relies on existing checkout equipment, and ingenious design characterization processes to testing result repeated calculation and check, has guaranteed that the detection data are true and reliable, can reflect the accuracy of detection of punching.Save production time and funds, finished the production task of magnetic cell smoothly.
For achieving the above object, the technical scheme that the present invention takes is: a kind of punching detection method, its principal feature comprises the steps:
1) punching is placed on sturdy compressing on the marble platform, guarantees that punching do not have buckling deformation; Can reflect punching true shape error.
2) detect: the laser tracker of laser tracker is measured ball be arranged on detection, the measuring basis face of measuring seat is arranged at punching side to be measured, guarantee that measuring seat well contacts with punching side to be measured in the measuring process with on the measuring seat; Laser tracker is arranged on suitable measuring position, makes laser tracker on each measurement point of punching to be measured measure ball and all can receive the laser that laser tracker sends; Open laser tracker and begin to measure,, guarantee in measuring process, to measure ball and measuring seat and do not have and relatively move,, also can adopt the magnetite that processes to measure ball and suck with measuring seat in order to avoid influence measuring accuracy along the slow traverse measurement seat in punching to be measured edge.
3) measurement data is handled: punching cartridge specified portions is measured repeatedly, this part measurement data is handled, draw the standard deviation of measurement; Change another piece punching, the duplicate measurements step draws the standard deviation of measurement.
A kind of punching detects and uses measuring seat, and its principal feature includes: measuring seat is hollow step cylindricality seat, and getting out of a predicament or an embarrassing situation is the measuring basis face; The upper surface is provided with the conical surface, is provided with laser tracker and measures ball on the conical surface.
Described punching detects and uses measuring seat, the conical surface of described upper surface is 45 °.
Described punching detects and uses measuring seat, and the terrace of appearing on the stage of described step cylindricality seat is the annular knurl face.
Beneficial effect of the present invention: the present invention, simple, accurately, reliable.When having overcome the measurement of use three-coordinates measuring machine simultaneously, the measuring error that flexural deformation brought of punching itself.Utilize measurement scheme of the present invention, successfully finish the development effort of the Chinese Academy of Sciences with the international cooperative project FAIR-superFRS superconduction dipolar magnet of German GSI (German heavy ion National Laboratory).Guarantee finishing according to plan smoothly of whole project, saved the funds of producing development.New method for large scale punching measurement has been proposed, for the production of this type of magnet later on provides experience.
