TL;DR: In this article, a large-scale slewing bearing axiality detects and correction of flank shape device, including the workstation, first radial error gauge head, first error data acquisition device, first pocket machining head, bracing piece.
Abstract: The utility model discloses a large -scale slewing bearing axiality detects and correction of flank shape device, including the workstation, first radial error gauge head, first error data acquisition device, first pocket machining head, bracing piece. By the radial error gauge head carries out the error -detecting to the outer ring raceway, compares the data that the detect shape that the outer ring raceway was drawn out in the match according to least spuares with the image of system, and the bracing piece carries out fine correction by the pocket machining head that corresponds to the outer ring raceway after turning over 90o. Can realize the frontier inspection and survey limit processing, detect and revise the mutually noninterfere, the utility model relates to a have two sets of symmetrical arrangement's detection correcting device, machining efficiency is high, and the equilibrium is good, is revising the in -process, only needs to place the device in slewing bearing's top, and detect by oneself and revise by installing, the degree of automation height, intensity of labour is little, and it is high to revise the precision, the utility model discloses simple structure, easy operation has better popularization nature.
