Description
Technical field
The present invention relates to a kind of thread chasing attachment, especially external screw thread whirlwind milling turning device.
Background technology
Cyclone milling head that known lathe is equipped with is made up of motor, belt pulley, knife bar, facing cutter rotating shaft, bearing, whirlwind housing, capping, connector, base.Because screw thread exists lead angle, require in milling process that facing cutter shaft axis and processed screw axis form angle, therefore on whirlwind base, plane manufactures inclined-plane, and angle equals lead angle.Just it is by being confined to the screw thread only processing a kind of specific lead angle.At present, usual adopted threaded whirling milling head, whirlwind housing side is connected with base side is vertical, is affixed rotation by two sides, adjusts lead angle around single-revolution axle, and establishes screw lock in this rotating shaft isocentric circular arc groove.Because base takes the form of standing, outside cyclone milling head orphan is suspended from, furthermore limit to by lathe locus, base cannot obtain ideal type to improve intensity, so show as integral rigidity deficiency.Because milling with whirling cutter is a kind of discrete intermittent-cutting, because vibration causes thread groove machined surface quality can not meet product design technology requirement.Therefore process capability can not maximumly play, and cutting speed, the depth of cut, the amount of feeding are restricted.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of whirling mill to cut external screw thread device, and its base rigidity is strengthened, and the different lead angle screw thread of energy milling, can bear vibration effect when higher rotation speed, larger cutting force, ensure crudy.
For solving the problems of the technologies described above, whirling mill of the present invention cuts external screw thread device, comprise relieving lathe middle carriage, described relieving lathe middle carriage is fixed with base, also comprise whirlwind housing, it is characterized in that: described base is connected by the arc surface matched each other with whirlwind housing, facing cutter rotating shaft is equipped with in whirlwind housing rotary hole, described facing cutter rotating shaft two ends are all provided with bearing, facing cutter rotating shaft between two bearings is provided with inner spacing collar, and described bearing, inner spacing collar side are provided with the capping be fixed on through screw on whirlwind housing; Facing cutter rotating shaft one end is provided with big belt pulley, the other end is provided with milling turning device; Described whirlwind housing upper is provided with supporting plate, is provided with motor above described supporting plate, and the main shaft of described motor is provided with small belt pulley, is provided with belt between described big belt pulley, small belt pulley.
After have employed technique scheme, because cyclone milling head coordinates with the great circle cambered surface of base through whirlwind shell alms bowl, be directly seated on lathe from top to bottom, steady reality is firm, rigidity increases, and can bear vibration effect when higher rotation speed, larger cutting force, ensures crudy.By the relative rotation of base with whirlwind housing, can the different lead angle screw thread of milling.
Described base and whirlwind housing binding site are provided with scale indication device; The relative position degree adjustment of base and whirlwind housing can be carried out intuitively according to the requirement of different lead angle.
Be provided with motor support plate above described supporting plate, described motor is arranged on motor support plate, is provided with arrangement for adjusting height between described supporting plate and motor support plate.After have employed technique scheme, by adjustment supporting plate height, small belt pulley, big belt pulley relative position can be adjusted, thus facilitate the tensioning of belt.
