Abstract
This article mainly is through the analysis aircraft engine on turbine disk key way unique feature, situations and so on processing craft, determined the design proposal, has completed the processing turbine disk key way horizontal-type broaching machine tongs design.
This tongs mainly uses in on the broaching 83076967 turbine disks the even cloth 47 fir tree's key way, because in this working procedure is apart from the key way center to the key way working surface the distance as well as 47 key ways records the even cloth to be very small tiredly, and the key way broaching processes the location to be many, as soon as therefore in this tongs design process, selects holds straight the surface and the short column took the localization datum, emphatically carried on to the positioning device and the spacing device systematically has designed in detail, uses the volume slightly, the rotation nimble, the ease of operation, the indexing precision high end tooth plate spacing device, in order to could reduce the labor intensity, enhanced the labor productivity, took the spacing device with the hydraulic gearDynamic system. Each installment has made reasonably, the correct arrangement to the tongs on, reduced the tongs volume as far as possible. Has summarized this tongs use and the adjustment method, and the generalized analysis enhanced the fir tree key way surface roughness the method.
Key word fir tree key way position error end tooth disc type graduated disc
