Description

Method and checkout gear that opposite machining tool main shaft is demarcated
Technical field
The present invention relates to machine tool technology, particularly the method checkout gear of opposite machining tool main shaft demarcation.
Background technology
Along with the development of Modern Manufacturing Technology is advanced by leaps and bounds, the requirement of the machining production automation is more and more higher, the processing of traditional workpiece endoporus adopts boring machine to realize, but axial length bigger hole and axiality are required than higher workpiece, and this method can not satisfy the demands.At this type of part processing, especially for the big hole of axial dimension, the application of two-sided boring-mill work lathe has obtained development fast, in order to improve the precision that two-sided machining tool is used in actual production, high efficiency, the calibration technique at center plays most important property in two-sided machining tool two main shafts.Therefore find a kind of pinpoint scaling method of two alignments of shafts of realizing fast in actual processing, to have great significance.
The scaling method of traditional two-sided machining tool two alignments of shafts referring to Fig. 1, is installed in two main shafts 10 of opposite machining tool, 10 ' detection probe 20, inspection rod 30 respectively; Main shaft 10,10 ' is installed in respectively on separately the column 40,40 '.Adopt fixing inspection rod 30, by mobile laser detection probe 20, three some A, B, C (referring to Fig. 3) on the cylindrical of detection inspection rod 30, can determine to examine the central point of rod by 3 detections, obtain one group and examine excellent centre coordinate data, above-mentioned coordinate data is input in the controller of machining tool of installation and measuring probe 20 and main shaft 10, this lathe is navigated to this coordinate points, thereby realize the demarcation of two alignments of shafts; Need directly not enter the process segment after having detected at mobile main shaft.
The shortcoming of said method is: bowlder laser detecting apparatus device at first moves in the spindle centerline direction outside detecting, main shaft drive detecting instrument moves up and down on the contact cylindrical and a bit finishes first detection then, after this moment, the laser detection probe will be return along the alignment of shafts, move to the detection of second of the excellent following realization of inspection once more, the then detection of the 3rd point, this kind testing process complexity, the stroke that probe moves in moving process is very big, cause its precision along with reduction, and then caused its coaxial precise decreasing, especially in high-accuracy lathe, can't satisfy the requirement of processing.
In addition, traditional scaling method laser detection probe 20 and the calibration position of inspection rod 30 are above workpiece 50 in reality processing, demarcate the back and process at the center of the through hole 501 of getting back to workpiece 50, getting back to workpiece through-hole 501 central process after demarcation has increased accumulated error.And this error can reach 0.02mm; Seriously reduced the precision of its machining hole.
Summary of the invention
The objective of the invention is to propose method and the checkout gear that a kind of opposite machining tool main shaft is demarcated, this method mainly is to solve existing deficiency when detecting the cylindrical realization demarcation alignment of shafts, reduce the shift motion of laser detection utensil in the calibration process, improve two main shaft concentricitys thereby reach, improve machine finish.
For achieving the above object, the technical solution used in the present invention is:
The method that opposite machining tool main shaft is demarcated is installed in detection probe and inspection rod respectively on two main shafts of opposite machining tool; It is characterized in that, examine excellent center and have round endoporus; Mobile detection probe and inspection rod, the through hole both sides from workpiece enter workpiece through-hole respectively, and navigate in the through hole of workpiece; Then detection probe is moved in the round endoporus of inspection rod, make detection probe contact on the internal circle of inspection rod circle endoporus a bit realize first detection; And then direct mobile detection probe on the internal circle of inspection rod circle endoporus, carry out second detection; In like manner, finish thirdly detection; Detect the central point of determining the inspection rod by 3 on the internal circle, obtain one group of coordinate data of examining excellent central point, the coordinate data of above-mentioned inspection rod central point is input in the controller of machining tool of installation and measuring probe, this machining tool is navigated to this coordinate points, thereby realize the demarcation of two alignments of shafts; Need directly not enter the process segment after having detected at mobile main shaft.
Further, the ultimate range that detection probe moves in the whole testing process is 1.5 times that the inspection rod is justified diameter of bore.
Described detection probe is laser detection probe or contact probe.
In addition, the checkout gear that opposite of the present invention machining tool main shaft is demarcated comprises laser detection probe, inspection rod on two main shafts that are installed in the opposite machining tool respectively; Main shaft is installed in respectively on the opposite machining tool column separately; It is characterized in that the excellent central part of described inspection has round endoporus.
The present invention is in order to solve the low process complicated phenomenon of traditional precision that cylindrical caused of utilizing laser detection instrument detection tool, elder generation's proposition will be examined rod and be made into the endoporus pattern, utilize the laser detection instrument in the interior circle of inspection rod, to detect 3 demarcation that realize its center, owing to be the detection that in endoporus, realizes, reduce the shift motion of its laser probe in testing process theoretically.Only need detection probe on both direction, to move the purpose that can reach demarcation. is owing to realized the endoporus detection; Can detect rear at the center of getting back to workpiece hole by former workpiece top the position of detecting; Change into directly and in workpiece hole, demarcating; This detection mode has reduced the error that moves to the center, hole after the demarcation; And this error worst error in the testing process just; Especially littler for diameter; And in the exigent situation of axiality; Traditional detection method can not meet the demands fully; Therefore utilize the method that detects the excellent inner circle of inspection to carry out the double-side processing machine bed alignment of shafts and demarcate the very high use value that has in high-precision machine tool
The invention has the advantages that:
1, the present invention adopts the laser detection probe to detect examining excellent endoporus, thereby realizes the demarcation of two alignments of shafts, and the mobile ultimate range of whole process laser detection probe is 1.5 times of inspection rod circle diameter of bore; Stroke is short, the precision height, and action is simple, dependable performance, the time is short, and accumulated error is low, and the application on high-speed precise machine tool has wide space.
2, testing process of the present invention is finished in the through hole inside of workpiece, has reduced traditional accumulated error that whole stroke causes when moving to workpiece inside after detection above the workpiece is finished; And this error accounts for 50% of whole testing process, and especially at the demanding workpiece of aperture small bore coaxial cable degree, the inventive method has very high use value.
