Abstract
The utility model discloses easy external threading device for a kind of lathe, comprise sleeve, sleeve right part is provided with tapering and forms Morse taper shank, Morse taper shank minor diameter one end is outwardly and for connecting machine tool tailstock, in the endoporus of sleeve, slide and be provided with screw die stationary magazine creel, the left part of screw die stationary magazine creel is fixedly connected with screw die; On sleeve, be provided with vertically gathering sill, gathering sill is arranged with two centered by the axis of sleeve; Described screw die stationary magazine creel outer wall is corresponding with described two gathering sills is fixedly connected with two feather keys, and feather key is positioned at gathering sill and is slidably matched with the cell wall of gathering sill.The utility model cost of manufacture and use cost are all lower, and working (machining) efficiency is compared manual external threading and greatly improved, and has good application value.Feather key can ensure that screw die can only move axially and can not rotate, can be simply, efficiently, reliably bar is carried out to external threading processing.
Description
Technical field
The utility model relates to a kind of external threading device.
Background technology
In industrial production, many columnar parts, bar-like member need to carry out external threading operation.In prior art, the means of external threading (external screw thread) mainly contain and use the manual external threading of screw die, use Lathe turning tool car external screw thread processed, use screw plate to twist the means such as external screw thread and mold pressing external screw thread.Use screw die manually to overlap external screw thread, although use more for convenience, labour intensity is higher, and working (machining) efficiency is lower.Use lathe car external screw thread processed, need again to use special lathe tool, and corresponding procedure, using comparatively inconvenience, processing cost is higher.
Utility model content
It is a kind of simple in structure, easy to use that the purpose of this utility model is to provide, the easy external threading device for lathe that processing cost is lower.
For achieving the above object, lathe of the present utility model comprises sleeve with easy external threading device, sleeve right part is provided with tapering and forms Morse taper shank, Morse taper shank minor diameter one end is outwardly and for connecting machine tool tailstock, in the endoporus of sleeve, slide and be provided with screw die stationary magazine creel, the left part of screw die stationary magazine creel is fixedly connected with screw die;
On sleeve, be provided with vertically gathering sill, gathering sill is arranged with two centered by the axis of sleeve;
Described screw die stationary magazine creel outer wall is corresponding with described two gathering sills is fixedly connected with two feather keys, and feather key is positioned at gathering sill and is slidably matched with the cell wall of gathering sill.
The left part of described screw die stationary magazine creel is fixedly connected with screw die by fastening screw.
Described gathering sill is located axially at the right part of sleeve.
The utility model is simple in structure, easy to use.In work, need not use special lathe tool, procedure that need not be special, cost of manufacture and use cost are all lower, and working (machining) efficiency is compared manual external threading and is greatly improved, and has good application value.Feather key can ensure that screw die can only move axially and can not rotate, utilize the rotation of processed bar, and stretch in screw die and the bar that processes on external screw thread pull screw die to move axially, can be simply, efficiently, reliably bar is carried out to external threading processing.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is that the A-A of Fig. 1 is to view.
Detailed description of the invention
As depicted in figs. 1 and 2, lathe of the present utility model comprises sleeve 1 with easy external threading device, sleeve 1 right part is provided with tapering and forms Morse taper shank 2, Morse taper shank 2 minor diameter one end are outwardly and for connecting machine tool tailstock, in the endoporus of sleeve 1, slide and be provided with screw die stationary magazine creel 3, the left part of screw die stationary magazine creel 3 is fixedly connected with screw die 4;
On sleeve 1, be provided with vertically gathering sill 5, gathering sill 5 is arranged with two centered by the axis of sleeve 1;
Described screw die stationary magazine creel 3 outer walls are corresponding with described two gathering sills 5 is fixedly connected with two feather keys 6, and feather key 6 is positioned at gathering sill 5 and is slidably matched with the cell wall of gathering sill 5.
The left part of described screw die stationary magazine creel 3 is fixedly connected with screw die 4 by fastening screw 7.
Described gathering sill 5 is located axially at the right part of sleeve 1, does not offer gathering sill on Morse taper shank 2.Because gathering sill 5 does not connect sleeve 1 left, therefore can stop feather key 6 to be drawn out sleeve 1 left.
Screw die 4, Morse taper shank 2 etc. are prior art, and its concrete structure repeats no more.
When use, bar to be processed is clipped in to three of lathe and grabs on chuck, the Morse taper shank in the utility model 2 is arranged on the tailstock of lathe, bar to be processed inserts screw die 4.Start lathe, lathe drives bar rotation, and bar stretches into the part of screw die 4 and extracts external screw thread, this place's external screw thread matches with the silk for external threading in screw die 4, along with bar rotation, bar pulls screw die 4, make screw die 4, screw die 4 fixed mounts and feather key 6 vertically the direction of bar move.Because feather key 6 is directed to groove 5 clampings, therefore can ensure that screw die 4 fixed mounts and screw die 4 can be because being driven and rotate by bar, ensure that screw die 4 can only move axially.Because gathering sill 5 does not connect sleeve 1 left, therefore can stop feather key 6 to be drawn out sleeve 1 left.After screw die 4 moves axially, bar more in depth injects screw die 4, thereby on bar, processes gradually the external screw thread of Len req.
