Title: AEROSPACE-GRADE BALL GRID PRECISION MACHINING SYSTEM
Abstract:
Disclosed is an aerospace-grade ball grid precision machining system, comprising a workbench (100), a rotating table (200), a linear displacement ball grid (300), a first angular displacement ball grid (400), a clearance elimination drive system (500), a second angular displacement ball grid (600), a swing seat (700), a universal ball seat (800) and a sway assembly (900). The workbench (100) is movably arranged on the rotating table (200). The linear displacement ball grid (300) measures the amount of movement of the workbench (100). The rotating table (200) is rotatably arranged on the swing seat (700) by means of the clearance elimination drive system (500). The first angular displacement ball grid (400) measures the amount of rotation of the rotating table (200). The swing seat (700) is arranged on the universal ball seat (800) in a swinging manner by means of the sway assembly (900). The second angular displacement ball grid (600) measures the amount of swing of the swing seat (700). Machined parts are fixed on the workbench (100). With the multi-dimensional operation and precision control of a machining machine, the machining efficiency and precision on machined parts are improved.
