A center frame device for machining aircraft landing gear and its clamping method

Abstract

The present invention disclosed a central frame device and its fixture method for aircraft landing rack processing. The central frame includes the base. The upper end of the base is set with a central frame.Set up the center of the support arm, and the three supporting arm points to the center of the ring structure, one of which is set up vertically; the three supporting arm is opened along the axis of the axis.Put the pores in the rod; the base is installed on the guide rail of the lathe. The center of the center of the center is parallel to the cable of the lathe.The processing method includes: step s1 :s8.The design structure of the present invention is simple, easy to load and unload and use, and is overall formed, one processing, and the overall structure is strong and accurate.The invention is accurately located during the part of the parts clip, and the offset error of the parts appears in real time during the processing process.

Description

technical field [0001] The invention relates to the technical field of numerical control machining, in particular to a center frame device for machining an aircraft landing gear and a clamping method thereof. Background technique [0002] For the clamping of the rotating parts of the aircraft landing gear, the lathe chuck is generally used to cooperate with the rear center of the tailstock. Sometimes, in order to ensure the accurate processing of the rotary body and the thin-walled outer cylinder, the purchased traditional center frame is generally used to clamp and fix the position of the workpiece. However, this kind of traditional center frame is generally made of cast iron, and its material is relatively hard. During the workpiece clamping process, it is often necessary to tap the center frame to adjust the position. In the case of repeated knocks, surface cracks often appear on the center frame. , so that the structural stability of the center frame is damaged. In add...

Problems solved by technology

However, this traditional steady frame is generally made of cast iron, and its material is relatively hard. During the clamping process of the workpiece, it is often necessary to tap the steady frame to adjust its position. In the case of repeated knocking, it often causes surface cracks in the steady frame. , which damages the structural stability of the center frame

In addition, the traditional center frame often adopts an integral circular ring hinged structure, and the steps are more cumbersome when disassembling and unloading workpieces, thereby reducing work efficiency, and the ring joints are easy to wear after multiple disassembly and assembly of workpieces, reducing the clamping accuracy. Resulting in a reduction in the machining accuracy of the workpiece
