Description
Technical field
It the utility model is related to lathe cutting techniques, more particularly to two-way turning tension tool.
Background technology
In the length of the hollow tube workpiece of lathe process, it is to use the hollow tube workpiece one end of chuck three-jaw tensioner mostly, adds
The work other end；Reprocess the other end in one end that hollow tube workpiece is processed in u-turn tensioner so that the process of processing is various, relatively
Time-consuming, it is difficult to ensures the concentricity at hollow tube workpiece both ends, now needs a kind of equipment of invention badly to solve this problem.
Utility model content
To overcome the process of the hollow tube workpiece of prior art lathe process various, it is difficult to ensure hollow pipe concentricity of workpiece
Problem, the utility model provide a kind of two-way turning tension tool.
The two-way turning tension tool of the utility model includes fixed tapered sleeve, tapered sleeve pull bar and rope nozzle set；The fixed tapered sleeve
Front end be hollow circular ring type, its central part is provided with circular port, and the fixed tapered sleeve middle part is provided with the conical surface；It is described
The front end of tapered sleeve pull bar is circular elongate bar, and it is applied in the circular port that the central part of the fixed tapered sleeve is set, institute
That states the rearmost end of tapered sleeve pull bar is provided with the conical surface；The rope nozzle set is a ring-like cylinder, and it has certain elasticity, the rope
Tapered sleeve is fixed described in nozzle set covering part, it wraps up the tapered sleeve pull bar, the rope nozzle with the space that the fixed tapered sleeve surrounds
The front-end and back-end of set are respectively arranged with the conical surface, and the conical surface of its front end is engaged with the conical surface of the fixed tapered sleeve middle part,
The conical surface of its rear end is engaged with the conical surface of the tapered sleeve pull bar rearmost end.
Compared with prior art, the two-way turning tension tool of the utility model is adapted to by selecting with the hollow tube workpiece
The tapered sleeve pull bar and rope nozzle set size, clamped one time just completes processing, greatly shortens the clamping time, while also ensure
The concentricity at both ends, greatly improves production efficiency.

Embodiment
In order that the purpose of this utility model, technical scheme and advantage are more clearly understood, below in conjunction with accompanying drawing and implementation
Example, the utility model is further elaborated.It should be appreciated that specific embodiment described herein is only solving
The utility model is released, is not used to limit the utility model.
Fig. 1 and Fig. 2 are referred to, the two-way turning tension tool 1 of the utility model includes fixed tapered sleeve 11, the and of tapered sleeve pull bar 12
Rope nozzle set 13.(herein and " on ", " under " described later, "front", "rear" are relative position, not for the front end of the fixed tapered sleeve 11
Absolute definition, while also become following when can be understood as overturning above) it is hollow circular ring type, its central part is provided with circle
Shape hole, the fixed middle part of tapered sleeve 11 are provided with the conical surface；The front end of the tapered sleeve pull bar 12 is circular elongate bar, and it is passed through
The central part for being through the fixed tapered sleeve 11 is provided with circular port, and the rearmost end of the tapered sleeve pull bar 12 is provided with cone
Face；The rope nozzle set 13 is a ring-like cylinder, and it has certain elasticity, and the rope nozzle covers fixes tapered sleeve described in 13 covering parts
11, it wraps up the tapered sleeve pull bar 12, the front-end and back-end point of the rope nozzle set 13 with the space that the fixed tapered sleeve 11 surrounds
Be not provided with the conical surface, the conical surface of its front end is engaged with the conical surface of the fixed middle part of tapered sleeve 11, the conical surface of its rear end with
The conical surface of the rearmost end of tapered sleeve pull bar 12 is engaged.
Referring to Fig. 3, when client needs the hollow tube workpiece 21 of lathe process, first selection and the hollow tube workpiece 21 are suitable
The rope nozzle set 13 and the tapered sleeve pull bar 12 matched somebody with somebody, then needing the hollow tube workpiece 21 of turning to be enclosed on the rope nozzle set
On 13, the fixed tapered sleeve 11 is connected with lathe spindle 31, the tapered sleeve pull bar 12 is connected with lathe pull bar 32, works as institute
Lathe pull bar 32 is stated when being moved under pulling force F is acted on, the tapered sleeve pull bar 12 also and then moves, the rearmost end of tapered sleeve pull bar 12
The conical surface extrude the conical surface of rope nozzle set 13, the rope nozzle set outside swell of 13 elastic deformations is forced, so as to reach tensioner institute
The purpose of hollow tube workpiece 21 is stated, now lathe can carry out turning work on the cutter 22 at the hollow both ends of tube workpiece 21
Industry.When the lathe pull bar 32 gives opposition, the tapered sleeve pull bar 12 will unclamp the rope nozzle set 13, the rope nozzle
Set 13 will autogenous shrinkage into original size so that the hollow tube workpiece 21 is in releasing orientation, now take out institute again
State hollow tube workpiece 21 and complete whole clamping process.
Compared with prior art, the two-way turning tension tool 1 of the utility model passes through selection and the hollow tube workpiece 21
The size of the tapered sleeve pull bar 12 and rope the nozzle set 13 of adaptation, clamped one time just complete processing, greatly shorten the clamping time, together
When also ensure the concentricity at both ends, greatly improve production efficiency.
The utility model preferred embodiment is the foregoing is only, is not intended to limit the invention, it is all new in this practicality
Any modification made within type principle, equivalent substitution and improvement etc. all should be included within the scope of protection of the utility model.
