Abstract
The utility model relates to a special tool of a righting type circular die holder for hinging (threading) external thread on link, and mainly comprises a circular die (2), a circular die case (1), a clamp nut (4) and a handle (3). A righting device is arranged on the circular die (2), the circular die (2) is not inclined during operation, the quality of the hinged threat is good, and the efficiency is good.
Description
Affiliated technical field
The utility model relates to the instrument of machining with circular die articulation screw thread (mantle fiber) usefulness.
Background technology
Now used mantle fiber instrument circular die twists hand, does not set upright the function of circular die, the easy deflection of circular die in operation, and it is crooked defective to make strand make the rod member screw thread that comes, even scraps.
Summary of the invention
In order to overcome the deficiency of the easy deflection of instrument circular die that existing mantle fiber uses, the utility model provides a kind of righting type circular die strand hand, makes circular die all the time perpendicular to rod member, can effectively prevent the circular die deflection.
The technical scheme that its technical problem of the utility model is adopted is: the place, lower surface at circular die is provided with several boss circular arcs, and circular arc is formed by several circular holes and center hole, and several boss circular arcs are the same center of circle, and perpendicular with the center of circle of circular die.After rod member inserted several boss circular arcs, several boss circular arcs can play the effect of setting upright rod member.
Description of drawings:
Below in conjunction with drawings and Examples the utility model is further specified.
Figure two is A-A profiles of figure one.
Figure four is A-A profiles of figure three.
Figure six is A-A profiles of figure five.
1. circular die boxes among the figure, 2. circular die, 3. handgrip, 4. clamp nut, 5. rod member.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described in detail, this righting type circular die strand hand by circular die box (1), circular die (2), handgrip (3), clamp nut (4), etc. form, as figure one.Clamp nut (4) is the upper end that is threaded in circular die box (1) in addition, and the center is provided with and the identical hole of circular die (2) nominal diameter, is provided with two holes of symmetry on the both sides at center, uses for loading and unloading.The center of circle of several boss circular arcs of the center of circle of the centre bore center of circle of clamp nut (4), circular die (2), circular die box (1) is on same vertical line.Several boss circular arcs are to be made by the center hole of circular die box (1) and several circular hole on every side, become several semicircle orifices at last, as figure two, the center hole center of circle of circular die box (1) and the center of circle of several boss circular arcs are the same center of circle and diameter, the diameter of the diameter of boss circular arc and rod member (5) matches, several boss circular arcs work to set upright rod member (5), several semicircle orifices should and circular die (2) on semicircle orifice alignment discharge iron filings.
This righting type circular die strand hand also can be designed to the structure as figure three, figure five, the design feature of figure three is, the upper end face of circular die box (1) can be unrestricted when using conversely greater than the diameter of rod member (5), and directly articulation is to the step root of rod member (5).The position of clamp nut (4) below circular die (2) is provided with several semicircle orifices of setting upright the boss circular arc and going out iron filings above.The diameter of arc diameter and rod member (5) matches.The design feature of figure five is: the several boss circular arcs that play centralizing function directly design on an end face of circular die (2), become one.The size of other size and circular die (2) matches.
This righting type circular die strand hand can make circular die (2) and rod member (5) keep vertical, the screw thread that articulation is come out, not deflection when the articulation screw.Quality is increased work efficiency well.
Claims (4)
1, a kind of righting type circular die strand hand, it is characterized in that, it is similar with circular die (2) to be provided with several its shapes of boss circular arc of setting upright at the end (bottom) of circular die box (1), several boss circular arcs are that the same center of circle and clamp nut (4), circular die (2) coexist on the vertical line, several boss circular arcs are to be made by the center hole above the circular die box (1) and several circular hole on every side, become several semicircle orifices at last.
2, righting type circular die according to claim 1 school hand is characterized in that the diameter of several boss circular arcs and the diameter of rod member (5) match.
3, righting type circular die strand hand according to claim 1 is characterized in that clamp nut (4) is located at the following position of circular die (2), is provided with several boss circular arcs and the semicircle orifice that goes out iron filings above.
4, righting type circular die strand hand according to claim 1 is characterized in that the direct design of several boss circular arcs that will play centralizing function becomes one on an end face of circular die (2), and other size and circular die (2) size matches.
