Background
With the rapid development of the aviation field in China, the machining requirements for various parts on the machine are continuously improved. In a part production plant, a large number of castings and die forgings exist, and many of them are critical parts. The quality of the processing quality of the composite material directly influences the overall performance of the airplane. This puts higher demands on our machine tool fixtures: both the grippers, locators and supports need to accommodate the machining of such blanks.
The blank surfaces of the castings and the die forgings are irregular. The small supporting surface of the auxiliary support can cause overlarge concentrated force to damage parts or destroy the support; the supporting surface of the auxiliary support is large, so that the supporting surface cannot completely fit the actual effect of the part or is in point contact.
The products such as castings and die forgings are often complex in appearance structure and large in size. Conventional up-down adjusted auxiliary supports sometimes have no operating space in the Z direction; sometimes the place where the support needs to be placed is too far from the outer edge of the part in the XY plane to be operated.
