PROFILE MODELING ASSEMBLY FOR LATHE CAMBERED SURFACE MACHINING

摘要

Disclosed is a profile modeling assembly for lathe cambered surface machining, a lathe comprising a cutter carrier, a tailstock and a cutter, and the profile modeling assembly comprising a cutter fixing member (1) for fixing a cutter, a telescopic rod (13), a profile modeling plate (21) having an arc-shaped surface, a profile modeling fixing member (3), and a spring (4), wherein the cutter fixing member (1) is connected to a cutter carrier; an end of the spring (4) that is sleeved on the telescopic rod (13) is connected to the cutter fixing member (1), and the other end thereof is fixedly connected to the telescopic rod (13); the cutter fixing member (1) is axially and slidably connected to the telescopic rod (13); one end of the telescopic rod (13) is fixedly connected to the cutter, and the other end of the telescopic rod is slidably connected to the arc-shaped surface of the profile modeling plate (21); and the profile modeling plate (21) is fixedly connected to a tailstock by means of the profile modeling fixing member (3) and is parallel to the horizontal plane. In a working process, since the telescopic rod is slidably connected to the cutter fixing member in axial telescoping manner, the telescopic rod can drive the cutter to feed according to the radian of the profile modeling plate, and then can machine shaft-like cambered parts. The profile modeling assembly can meet the requirement of machining shaft parts by means of a simple structure.
