Abstract

The utility model relates to a thread whirlwind milling, which comprises a frame structure bed, a spindle dynamic and a quick-return motion motor, wherein a machine tool spindle, a feed lead screw, a big carriage, a small carriage, a whirlwind milling head, and a horizontal-vertical driving and reversing feed mechanism are arranged on the bed. The big carriage is arranged on a circular shaft track, and the small carriage, a cross feed cam, a quick-return motion registration switch, a cross withdrawing spring and a size locating piece are arranged on the big carriage. The spindle is driven by a gear and is connected with one end of the feed lead screw, the quick-return motion motor is driven and is connected with the other end of the feed lead screw, the whirlwind milling head is arranged on the small carriage, and a longitudinal feed half nut and a quick-return motion half nut are arranged on the two sides of the feed lead screw which is arranged on the lower of the small carriage. The cross feed cam acts on the small carriage to crossly feed, simultaneously the longitudinal feed half nut is meshed with the feed lead screw. The cross withdrawing spring acts on the small carriage to crossly withdraw, the quick-return motion half nut is meshed with the feed lead screw, simultaneously the small carriage acts on the registration switch to start the quick-return motion motor to longitudinally withdraw, the size locating piece guarantees the dimensional precision of a workpiece, and the whole processing of the workpiece is capable of being completed through operating the cam.

Fig. 2 is the local figure of gear drive.
Fig. 3 is assembling diplopia figure of the present utility model.
Fig. 4 is the I-I half-nut leading screw partial sectional view of Fig. 3.
1. main shaft power among the figure, 2. driving gear, 3. transition gear, 4. driven gear, 5. main shaft, 6. frame-type lathe bed, 7. feed leading screw, 8. saddle, 9. upper slide rest, 10. cyclone milling head, 11. rewind down motors, 12. rewind down limit switches, the cam 13. cross feed, 14. rewind down half-nuts, 15. longitudinal feed half-nuts, 16. horizontal withdrawing spring, 17. sizing parts.
The specific embodiment
In the accompanying drawings, lathe bed (6) is a frame structure, and track is two fine finishining circular shafts.Main shaft (5) is located on the framework lathe bed (6), by the chain main shaft power (1) that is in transmission connection, connects an end of feed leading screw (7) by gear drive.Feed leading screw (7) is located at circular shaft track top and is parallel to the circular shaft track, the end band rewind down motor (11) that is in transmission connection.Saddle (8) sliding connection is connected with upper slide rest (9) dovetail guide on the circular shaft track.(8) adorn horizontal withdrawing spring (16), size rewind down limit switch (12) on the saddle.Dress cyclone milling head (10) above the upper slide rest (9) is installed longitudinal feed half-nut (15) and rewind down half-nut (14) below.Gear drive is made up of driving gear (2) (replaceable), driven gear (4), transition gear (3) (can adjust).Change driving gear (2) and just can change work piece pitch.Feed leading screw (7) is a 5mm pitch T type leading screw.
During machining screw, change driving gear (2) by the requirement of workpiece pitch.Adjust two half-nuts (14) (15), sizing part (17) position by the requirement of workpiece pitch.Workpiece is contained on (5), start main shaft power (1), workpiece and feed leading screw rotate, and operate cam (3) effect upper slide rest (9) the drive cyclone milling head (10) of crossing feed and cross feed, and upper slide rest (9) longitudinal feed half-nut (14) down meshes with feed leading screw (7).Saddle (8) vertically moves.Drive cyclone milling head (10) processing work.Completion of processing is operated cam (13) upper slide rest (9) under horizontal withdrawing spring (16) effect of crossing feed and is driven cyclone milling head (10) withdrawing.Longitudinal feed half-nut (15) is thrown off with the feed leading screw below the upper slide rest (9) simultaneously, rewind down half-nut (14) and the engagement of feed leading screw.At this moment, upper slide rest effect rewind down limit switch (12) has been opened rewind down motor (11), and saddle (8) is stepped back fast.
