Abstract

The utility model relates to a fast thread-separating device used for processing a multiple-threaded screw and a multiple-threaded nut, which belongs to the technical field of the mechanical workout and comprises a fixed disk, a thread-separating rotating disk, a fastener and a pin ejector, wherein the fixed disk is coincident with the thread-separating rotating disk, the fastener fastens the fixed disk and the thread-separating rotating disk into an integer, the edge of the outer side of the fixed disk is provided with the pin ejector, the thread-separating rotating disk is provided with a hollowness which is corresponding to the pin ejector, and the thread-separating rotating disk at the clockwise side of the hollowness is provided with a tapered groove. When the fast thread-separating device is used, the thread-separating rotating disk drives the workpiece to rotate for processing a first thread through a workpiece connector; when the fast thread-separating device is stopped, the thread-separating rotating disk is anticlockwise rotated manually, a pin roll is extruded from the first hollowness through the tapered groove and enters into the next hollowness, and the fast thread-separating device can process the second thread. The utility model has convenient and fast operation, safe and reliable use property and simple structure.

Description

The quick minute head unit that is used for machine tool processing multiple-threaded screw, nut

Technical field:

The utility model belongs to the Machining Technology field, is a kind of branch head unit that is used for machining screw rod, nut.

Background technology:

Screw thread on most of screw rods and the nut is a bull, generally form by the parallel screw thread in two to four roads, help efficiently and easily screw rod being screwed in the nut, existing machine tool is when multiple-threaded screw rod of processing and nut, the method that adopts is to utilize measuring instrument to help the travelling workpiece position after one screw thread finished in turning, descend one thread turning again, it is slow to adjust work speed, and needs the technical merit and the experience of certain altitude.

Summary of the invention:

The technical problems to be solved in the utility model is to disclose a kind of easy to operate quick minute head unit that is used for machine tool processing multiple-threaded screw, nut.

The scheme of the utility model technical solution problem is to adopt fixed disk, the parted hair rotating disk, fastener and ejector pin device constitute branch head unit fast, wherein fixed disk is a disklike body, rotating disk is annular disk-shaped body separately, fixed disk overlaps with the parted hair disk position, the axial section body of fastener is the T font, shape is similar to rivet, be buckled in place, center of turntable hole separately, by screw fixed disk and parted hair rotating disk are fastened as one, be fixed with the main shaft connector at fixed disk lateral surface middle part, the ejector pin device is equipped with in fixed disk lateral surface edge, have through hole on the fixed disk of ejector pin device position, the ejector pin device is by shell body, bearing pin and spring constitute, shell body is fixed on the fixed disk, bearing pin left side part is contained in the shell body, another partly passes the through hole of fixed disk, the termination contacts with the parted hair rotating disk, be fixed with back-up ring on the bearing pin, back-up ring is in shell body, and be close on the fixed disk lateral surface, spring is on bearing pin, one end contacts with back-up ring, the other end contacts with shell body rear end inwall, have two to five isometrical equally distributed recesses on the card of corresponding fixed disk on the rotating disk separately, the recess position is corresponding with the lead to the hole site of fixed disk, and clockwise side, recess place has the domatic groove on the rotating disk separately, on the rotating disk workpiece connector is arranged separately.During operation; the main shaft connector is fixed on the lathe spindle; rotating disk is connected with workpiece to be machined separately; this moment bearing pin top therein in recess; the lathe tool alignment pieces of lathe; start lathe; lathe spindle drives the fixed disk rotation by the main shaft connector; rotating disk is rotated counterclockwise because bearing pin in recess, can drive separately by bearing pin, sees accompanying drawing two; thereby make separately rotating disk process the first road screw thread by the part rotation of starting building of workpiece connector belt; shut down, manually rotate counterclockwise rotating disk separately then, see accompanying drawing two; this moment, fixed disk was motionless; bearing pin is extruded in first recess by the domatic groove, and enters next recess, and the lathe spindle relative position is constant like this; moving appears in workpiece and lathe spindle position; can process the second road screw thread, workpiece needs several roads screw thread, and side rotating disk separately should have several recesses.

The utility model is easy to operate, quick, and serviceability is safe and reliable, and is simple in structure.
