The invention relates to a groove
machining device for a thin plate, in particular to a groove
machining device. The groove
machining device for the thin plate aims to solve the problems that a thin-wall light part is easy to deform and the precision is difficult to control in a
machining process due to the characteristics of
large size,
irregular shape and low rigidity of a thin-wall light part.The groove machining device comprises a mechanical arm, and further comprises a machining mechanism, a clamping and fixing mechanism and a knife rest changing
assembly, wherein the machining mechanismcomprises a quick-change block movable end, a quick-change block fixed end, an adapter, a motorized spindle, a motorized spindle fixed base, a pressing cover plate and a
milling cutter, the mechanical arm is connected with the quick-change block fixed end, the quick-change block is connected with the quick-change block movable end, the adapter is connected with the quick-change block movable end,the motorized spindle fixed base is fixedly installed at the other end of the adapter, the
milling cutter is installed on the motorized spindle, the motorized spindle is installed on the motorized spindle fixed base and the pressing cover plate, the clamping and fixing mechanism is close to the mechanical arm and arranged below the machining mechanism, and the knife rest changing
assembly is arranged close to the mechanical arm. The method is applied to the field of groove machining of the thin plate.
