For achieving the above object, the technical solution of the utility model is as follows:
A kind of threading clamp comprises die sleeve and taper shank, and described die sleeve is cylindrical-shaped structure, and its end face axially offers a screw die blind hole, is equiped with screw die in the described screw die blind hole, and described die sleeve bottom surface axially offers a rectangular-shaped guiding blind hole;
Described taper shank front portion be one with the suitable rectangular-shaped guide rod of described guiding blind hole, described guide rod is arranged in the described guiding blind hole, and with the sliding-contact of described guiding blind hole; Described screw die slides along the front and back of described guide rod by described guiding blind hole and realizes moving forward and backward; Described taper shank rear portion is fixedly arranged on the lathe tailstock.
Preferably, offer vertically a waist-shaped hole that connects with described die sleeve side on the described guiding blind hole sidewall.
Preferably, described guide rod front end side also is provided with a guiding screw, the bolt thread end is assigned in described waist-shaped hole screw in described guiding screw, and described bolt can slide front and back in described waist-shaped hole.
Preferably, described die sleeve side also offers at least 3 and evenly distributes along described die sleeve annular surface, and the fastening screw that communicates with described screw die blind hole, and it is fastening to screw in the screw die that described fastening screw will be installed in the described screw die blind hole by trip bolt.
Pass through technique scheme, threading clamp of the present utility model, simple in structure, easy to operate, can utilize engine lathe to carry out automatic mantle fiber, both avoided using the expensive of electronic Special threading machine, abandoned again manual threading device inefficiency, the shortcoming of mantle fiber low precision has significantly reduced operating personnel's labour intensity, laborsaving during joint, mantle fiber efficient and precision are all higher.

The specific embodiment
Below in conjunction with the accompanying drawing among the utility model embodiment, the technical scheme among the utility model embodiment is clearly and completely described, obviously, described embodiment only is the utility model part embodiment, rather than whole embodiment.Based on the embodiment in the utility model, those of ordinary skills are not making the every other embodiment that obtains under the creative work prerequisite, all belong to the scope of the utility model protection.
The utility model provides a kind of threading clamp, its operation principle be by the anterior setting of described taper shank can before and after the die sleeve that slides, the screw die that drives the die sleeve front end moves forward and backward, the mantle fiber of finishing screw die feeds, and then finishes mantle fiber.
Below in conjunction with embodiment and the specific embodiment the utility model is described in further detail.
Embodiment.
As shown in Figure 1, Figure 2, Figure 3 and Figure 4, a kind of threading clamp comprises die sleeve 1 and taper shank 2, die sleeve 1 is cylindrical-shaped structure, its end face axially offers a screw die blind hole 3, is equiped with screw die 4 in the screw die blind hole 3, and die sleeve 1 bottom surface axially offers a rectangular-shaped guiding blind hole 5; Taper shank 2 front portions be one with the suitable rectangular-shaped guide rod 21 of guiding blind hole 5, guide rod 21 is arranged in the guiding blind hole 5, and with 5 sliding-contacts of guiding blind hole; Screw die 4 slides along the front and back of guide rod 21 by guiding blind hole 5 and realizes moving forward and backward; Taper shank 2 rear portions are fixedly arranged on the lathe tailstock.Offer vertically a waist-shaped hole 6 that connects with die sleeve 1 side on guiding blind hole 5 sidewalls.Guide rod 21 front end sides also are provided with a guiding screw 7, bolt 8 ends of thread are assigned in waist-shaped hole 6 screw in screw 7, and bolt 8 can slide in waist-shaped hole 6 interior front and back.Die sleeve 1 side also offers at least 3 and evenly distributes along die sleeve 1 annular surface, and the fastening screw 9 that communicates with screw die blind hole 3, and it is fastening to screw in the screw die 4 that fastening screw 9 will be installed in the screw die blind hole 3 by trip bolt 10.
