A Method for Generating Compensation Path of Online Measuring Hub

Abstract

An online measurement hub compensation path generating method includes the following steps that (1) a hub assisting line and assisting points are generated by utilizing a hub model; (2) a measurement data file is generated, specifically, (2.1) measurement points in different directions are created through the assisting line and the assisting points, the measurement points include whole points used for whole hub compensation and window points used for local window compensation, and the whole points and the window points are obtained by creating the measurement points on a curve; (2.2) according to hub characteristics, measurement points of the rest of windows are created, and circumferential marshalling is conducted; (3) all the created measurement points are ranked in an optimized mode, and a path suitable for measurement is generated; and (4) according to measurement options, measurement theoretical data are calculated, and the measurement path is output and finally guided into a machine tool control system. According to the online measurement hub compensation path generating method, manual ranking is not needed, manual calculation is replaced with automatic calculation for compensation values, the using difficulty and calculation amount are reduced, manual input of theoretical compensation values is not needed, and efficiency is improved.

Description

technical field [0001] The invention relates to the field of hub processing, in particular to a method for generating compensation paths for online measurement of hubs. Background technique [0002] In the development process of the automobile industry, the personalized processing market has become a strong support. In recent years, more and more wheel hub manufacturers have production needs for wheel hub processing, and a series of problems in the process of wheel hub processing must be solved with the help of online measurement technology. Online measurement technology is a technology that realizes automatic detection of workpiece processing quality on the machining center. This technology can compensate the processed workpiece in real time to improve delivery efficiency, reduce error accumulation, and improve processing quality.

Problems solved by technology

[0003] When the traditional online measurement technology is applied to hub compensation, it is first necessary to create measurement points one by one. When there are many hub windows, the work is repetitive and cumbersome. It is also necessary to manually sort the measurement points and output the path. When performing hub compensation, manual calculation is required Each window and the overall theoretical compensation value, and finally manually input the theoretical value into the software, so as to realize the comparison with the actual compensation value and compensate to the processing path. This method requires a large amount of calculation, complex calculation and error-prone
