Self-adaptive clamp for thin-wall long beam type part milling and using method

Abstract

The invention discloses a self-adaptive clamp for thin-wall long beam type part milling and a using method and belongs to the technical field of aviation process equipment designing and manufacturing.The self-adaptive clamp for thin-wall long beam type part milling comprises a bottom plate, an installing frame, an oil way plate, external thread type supporting cylinders, an installing block, an oil plug, a cushion plate, pressing plate assemblies, plane moving direction steel ball screw supporting pieces, an energy accumulator, a fast inserting male connector, a fast inserting female connector, a pump assembly, a combined guide pipe, hoisting rings and screws. Due to the application of the self-adaptive clamp for thin-wall long beam type part milling and the using method, the accurate positioning problem of long beam type parts in a definitely closed space is solved, and therefore the machining precision of the thin-wall long beam type parts is guaranteed, the manufacturing error accumulation is reduced, and finally the parts meet the delivery requirement.

Description

technical field [0001] The invention belongs to the technical field of aviation process equipment design and manufacture, and relates to an adaptive fixture for milling thin-walled long beam parts and a use method thereof. Background technique [0002] In the process of aircraft product processing, the processing difficulty of thin-walled long beam parts is relatively high. The structure of the part is poor in manufacturability. After a series of cold, heat and strengthening processes, severe deformation will inevitably occur. The hardness and yield strength of the part material after quenching are too large, so that only local small-area CNC finishing can be carried out, and accurate machining cannot be achieved. Positioning, the wall thickness of the part is thin and closed, and the deformation of the part is relatively large during processing. Contents of the invention [0003] The object of the present invention is to propose an adaptive fixture for milling of thin-wa...
