Abstract

The invention discloses a double-driving shaft composite automatic finishing method for a blisk. The method comprises the following steps of: machining by using special equipment with a rotary working table, wherein the equipment is provided with a fixed rotation axis; rotating a machined workpiece around the rotation axis relative to the rotary working table, wherein the rotation axis of the workpiece is parallel to the rotation axis of the rotary working table but is not coincident with the rotation axis of the rotary working table; revolving the machined workpiece around the rotation axis of the rotary working table during the rotation; and performing composite finishing operation on the machined workpiece by using a planar abrasive tool or/and a powdery or paste abrasive material under the motion condition. By the method, a completely new process is provided for improving the surface quality of a large-sized part with a complex shape and a high requirement on surface quality. A machining alternative method is found during the polishing of a large number of manually polished parts. The method has higher social value and economic value.

Description

Technical field: [0001] The invention relates to the technical science of finishing processing, and in particular provides a dual-drive shaft composite automatic finishing processing method suitable for integral blisk parts. Background technique: [0002] In the prior art, the finishing methods are relatively simple, and many of them are manually operated. Even when automated, the forms of motion involved are uncomplicated and their technical effects are often limited. [0003] Therefore, people expect to obtain an automatic finishing method with better technical effect, which is especially suitable for integral blisk parts. Invention content: [0004] The purpose of the present invention is to provide an automatic finishing method with better technical effect, which is especially suitable for integral blisk parts. [0005] The invention provides a compound automatic finishing method with double driving shafts of the whole blisk, which is characterized in that: special e...
