Abstract
The utility model proposes a kind of lathe tapping and the dual-purpose frock of mantle fiber, tap and die can be made to exchange, and can prevent that strength is excessive causes cone to fracture or screw die crumbles.Described frock comprises knife bar, and knife bar is connected with chuck, is provided with overload protective device in the screwed hole of chuck sidewall, and lining, circular die are arranged in the inner chamber of chuck, and lining is connected with screw tap, and the outer wall of lining and circular die is all provided with the groove coordinated with overload protective device.When the utility model uses, during work, lathe spindle drives workpiece to rotate, and screw tap or circular die and composition integrally, slide with in the groove being rotated in knife bar of workpiece, thus realize tapping or mantle fiber.Only according to screw tap specification more resleeve, during mantle fiber, chuck need be changed according to the specification of circular die during the tapping of this frock.When the strength of tapping or mantle fiber is excessive, overload protective device can squeeze in chuck screwed hole by tap and die, avoids screw tap and to fracture or screw die crumbles and causes product rejection.
Description
Technical field
The utility model relates to a kind of frock be used on lathe, is specifically related to a kind of frock that can realize tapping and mantle fiber.
Background technology
Current tapping and mantle fiber are general all with drilling machine or manual processing, use drilling machine handling ease because strength is excessive to cause screw tap to fracture or screw die crumbles and makes product rejection, make to process by hand, waste time and energy, efficiency is low.And tap and die kit can not exchange, need to prepare corresponding kit, inconvenient management and according to different size.
Utility model content
The utility model proposes a kind of lathe tapping and the dual-purpose frock of mantle fiber, tap and die can be made to exchange, and can prevent that strength is excessive causes cone to fracture or screw die crumbles.
The technical solution of the utility model is achieved in that a kind of lathe tapping and the dual-purpose frock of mantle fiber, comprise knife bar, knife bar is connected with chuck, overload protective device is provided with in the screwed hole of chuck sidewall, lining, circular die are arranged in the inner chamber of chuck, lining is connected with screw tap, and the outer wall of lining and circular die is all provided with the groove coordinated with overload protective device.
Described overload protective device comprises the spring be arranged in chuck sidewall thread hole, and spring one end is provided with screw, the other end is provided with steel ball.
Described chuck is arranged in the guide pin bushing of knife bar end, is provided with bolt in the screwed hole of guide pin bushing sidewall, and chuck end is provided with the stopper slot mated with bolt.
When the utility model uses, during work, lathe spindle drives workpiece to rotate, and screw tap or circular die and composition integrally, slide with in the groove being rotated in knife bar of workpiece, thus realize tapping or mantle fiber.Only according to screw tap specification more resleeve, during mantle fiber, chuck need be changed according to the specification of circular die during the tapping of this frock.When the strength of tapping or mantle fiber is excessive, overload protective device can squeeze in chuck screwed hole by tap and die, avoids screw tap and to fracture or screw die crumbles and causes product rejection.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Fig. 1 is structural representation of the present utility model.
Fig. 2 is screw tap structural representation.
Fig. 3 is circular die structural representation.
Wherein: 1, knife bar; 2, bolt; 3, chuck; 4, steel ball; 5, screw; 6, spring; 7, lining; 8, screw tap; 9, circular die; 10. groove, 11. guide pin bushings.
Detailed description of the invention
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not paying the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
As shown in Figures 1 to 3, a kind of lathe tapping and the dual-purpose frock of mantle fiber, comprise knife bar 1, knife bar 1 is connected with chuck 3, overload protective device is provided with in the screwed hole of chuck 3 sidewall, lining 7, circular die 9 are arranged in the inner chamber of chuck 3, and lining 7 is connected with screw tap 8, and the outer wall of lining 7 and circular die 9 is all provided with the groove 10 coordinated with overload protective device.
In the utility model, knife bar 1 is band tang Morse taper shank, knife bar 1 and tail stock sleeve connection, during work, lathe spindle drives workpiece to rotate, screw tap or circular die and interchangeable chuck 3 form one, slide, thus realize tapping or mantle fiber with in the groove being rotated in knife bar of workpiece.Only according to screw tap specification more resleeve, during mantle fiber, chuck need be changed according to the specification of circular die during the tapping of this frock.When the strength of tapping or mantle fiber is excessive, overload protective device can squeeze in chuck screwed hole by tap and die, avoids screw tap and to fracture or screw die crumbles and causes product rejection.
In the utility model, described overload protective device comprises the spring 6 be arranged in chuck 3 sidewall thread hole, and spring 6 one end is provided with screw 5, the other end is provided with steel ball 4.Two overload protective devices are symmetrical arranged, and when the strength of tapping or mantle fiber is excessive, steel ball 4 can squeeze in chuck screwed hole by screw tap and circular die, avoid screw tap and to fracture or screw die crumbles and causes product rejection.
In the utility model, described chuck 3 is arranged in the guide pin bushing 11 of knife bar 1 end, is provided with bolt 2 in the screwed hole of guide pin bushing 11 sidewall, and chuck 3 end is provided with the stopper slot mated with bolt 2, and bolt 2 can prevent chuck from rotating.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
