[Abstract]:Roller is an indispensable part of rolling bearing. The shape of spherical roller is the most complex in rolling body. The rolling surface of roller is a revolving body with convex spherical surface, which is difficult to process and measure.On the basis of deep analysis and research on the structural characteristics and dimension control conditions of spherical roller, a set of non-contact and high-precision spherical roller is proposed in this paper, combining with optical non-contact three-dimensional measurement technology.A special measurement system with full parameters.The related theories and methods of optical non-contact measurement technology are analyzed, and a special measuring system platform for roller based on optical triangulation method is established.The system adopts the digital integrated laser probe which combines the green LED light source HL-CCD optical system and the high-speed digital processing module to realize the high precision digital measurement and the high speed signal acquisition and processing of the measured surface.According to the structure characteristics of spherical roller, the processing algorithm of small sample and discrete data is studied to evaluate the radius of spherical roller with small arc and large radius.Combined with the mature technology of angular displacement table, a kind of X-Y bidirectional orthogonal coupling angle adjustable rotary table is proposed.It has remarkable characteristics when there is no perpendicularity between the end plane and the axis of rotation of the non-contact light screen measuring instrument and the end plane of the rotated parts, the computer integrated hardware control system is constructed, and the controller of the optical probe is constructed.Motion controller, grating counter and driving control module are combined to realize the automatic measurement of parts.The software system of system setup, data measurement and file operation is constructed.The system takes Windows XP/7 as the development environment and Visual C as the development platform, and establishes the system structure and workflow of the software system. A large number of experimental applications show that the developed measurement system has friendly interface, convenient operation and complete functions.It can meet the requirements of function and precision of product inspection.
