A lathe tool holder for machining internal and external threads, relating to the technical field of lathe tool holders, and comprising: a tool fixing holder (1), an adjusting shaft sleeve (4), a vertical distance adjusting assembly (5), an adjusting base (6), a supporting module (7), and a fixed spindle (8). The fixed spindle (8) is fixed to the left side of the adjusting base (6), and the adjusting shaft sleeve (4) is fixed to the right side of the supporting module (7); one end of the tool fixing holder (1) is fixed to a tool by means of fixing bolts (2), the other end of the tool fixing holder penetrates through the adjusting shaft sleeve (4), and the tool fixing holder (1) is fixed by means of adjusting bolts (3) provided on the side; the supporting module (7) and the adjusting base (6) are matchingly mounted in a sliding mode, and an internal adjusting structure of the vertical distance adjusting assembly (5) is matchingly disposed inside the adjusting base (6) and is in matching linkage with the supporting module (7) by means of an internal structure thereof. The adjusting bolts (3) can adjust the lateral distance of the tool fixing holder (1) in the adjusting shaft sleeve (4), the vertical distance adjusting assembly (5) is used for adjusting the displacement of the supporting module (7) in a vertical direction, the complementation of the adjusting bolts and the vertical distance adjusting assembly improves the overall range of movement of the tool holder, and the machining requirements of large-size workpieces are satisfied.

Abrégé

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.
