Title Title Title Title : : : : Based on non-contact automatic contour detection of theknife and researchAbstract Abstract Abstract AbstractIn order to meet the user requirements of the machining accuracy andefficiency, more machine manufacturers and users will want to make itpossible for the machine equipped with a high precision device.The ball screw nut processing in contact with the external thread on theknife in different ways, because the ball nut structure of small size, theinternal space is very limited, so that the inner threaded racewaynon-contact automatic tool research and design principles of difficultyplus large. Also for this internal thread contour detection of difficultyis also increased. This paper focuses on the principle based on non-contactball nut raceway automatic knife grinding technology and its reign contourdetection technology, on the one hand to meet the thread in the finishingworks of the knife process requirements, on the other hand, detected afterprocessing the nut thread accuracy and improve efficiency.In the automatic study of the knife, according to the grinding finishingrequirements for the design of several automatic knife, comprising thesingle-switch type (pided into high and low, the low level of two cases),double switch formula (pided into the first low to high and high-low twocases) and improved the knife method through experiments compared theaccuracy of various methods for the knife, and ultimately raised the knifeoptimization method.Detection of the profile shape, the design corresponding integrationfixture, using rice bowl sensor IFS 2402/90-10 experiment, thedisplacement sensor measurement mode selected by the sensor, the sensor probe to obtain the distance to the inner threaded surface, through thedata processing, internal thread fitting silhouette.The text of the proposed non-contact automatic tool detection programs andprofile shape of the actual programs on the ball nut grinding and qualitytesting have referential significance.
Keywords: ball nut, inner spiral raceway, automatic tool,study of contourdetection principle experiment
