Abstract
The utility model discloses a kind of screw thread secondary process tool, screw die fixing seat one end is cannula structure, the other end is rectangular configuration, screw die fixing seat is arranged on lathe tailstock, and end and the lathe tailstock of rectangular configuration are fastenedly connected, and are provided with threaded hole in the cannula structure of screw die fixing seat one end, screw die fixing bolt is provided in threaded hole, screw die is arranged in the cannula structure of screw die fixing seat, and the overall diameter of screw die is less than the interior diameter of screw die fixing seat cannula structure, is connected by screw die fixing bolt.The utility model structure is simple, the interior diameter of the cannula structure of screw die fixing seat is greater than the overall diameter of screw die, screw die fixing bolt is provided in cannula structure, in workpiece process, since the interior diameter of cannula structure is greater than the overall diameter of screw die, make have certain gap between screw die and screw die fixing seat, screw die can automatically adjust the center line with workpiece according to the power of workpiece during the work time, meet design requirement to reach accuracy of thread, workpiece bows is avoided to deform.
Description
Technical field
The present invention relates to screw thread process fields, and in particular to a kind of screw thread secondary process tool.
Background technique
Two methods are processed using craft or threading tool to screw thread process in machine-building at present；It is needed when manual processing
By on clamping workpiece to chuck, screw tap or screw die targeting part are to positive workpiece, with spanner clamping taper shank or screw die, rotate screw tap or
Screw die is completed, large labor intensity and low efficiency, when threading tool machining, on clamping workpiece to machine chuck, and chuck rotation,
Threading tool processing, needs multiple feed to complete, and existing processing method inefficiency, accuracy of thread does not reach requirement, and workpiece is easy
Bending deformation.
Summary of the invention
In conclusion the present invention provides a kind of screw thread secondary process tool in order to overcome the shortcomings of prior art problem,
It is to make screw die is opposite with screw die fixing seat to be flexibly connected, workpiece for gap is provided between screw die and the setting of screw die fixing seat
It is installed in screw die, screw die moves in a certain range with workpiece, and workpiece is made to correspond to center line automatically with screw die.
In order to solve the above technical problems, the technical solution adopted by the present invention are as follows:
A kind of screw thread secondary process tool, in which: including screw die fixing seat, screw die fixing bolt, screw die；The screw die
Fixing seat one end is cannula structure, and the other end is rectangular configuration, and the screw die fixing seat is arranged on lathe tailstock, rectangle knot
The end of structure is fastenedly connected with lathe tailstock, is provided with threaded hole, threaded hole in screw die fixing seat one end cannula structure
It is inside provided with screw die fixing bolt, threaded hole is matched with screw die fixing bolt, and the screw die is arranged in screw die fixing seat
Cannula structure in, the overall diameter of the screw die is less than the interior diameter of screw die fixing seat cannula structure, passes through the fixed spiral shell of screw die
It tethers and connects.
Further, it is provided with card slot on the screw die outer end face, card slot is corresponding with screw die fixing bolt.
Beneficial effect
1, the configuration of the present invention is simple, the interior diameter of the cannula structure of screw die fixing seat are greater than the overall diameter of screw die, casing knot
Screw die fixing bolt is provided on structure, in workpiece process, since the interior diameter of cannula structure is greater than the overall diameter of screw die,
Make have certain gap between screw die and screw die fixing seat, screw die during the work time can according to the power of workpiece automatically adjust with
The center line of workpiece avoids workpiece bows from deforming so that reaching accuracy of thread meets design requirement.
Detailed description of the invention
Fig. 1 is the structural diagram of the present invention；
1. screw die fixing seat；2. screw die fixing bolt；3. screw die.
Specific embodiment
The present invention is described in further detail with reference to the accompanying drawing.
As shown in Figure 1, a kind of screw thread secondary process tool, including screw die fixing seat 1, screw die fixing bolt 2, screw die 3；Institute
The screw die fixing seat 1 stated is arranged on lathe tailstock, is fastenedly connected with lathe tailstock, and described 1 one end of screw die fixing seat is set
Pipe structure, the other end are rectangular configuration, are provided with threaded hole, threaded hole and plate in the cannula structure of the screw die fixing seat 1
Tooth fixing bolt 2 complements one another use, and the screw die 3 is arranged in the cannula structure of screw die fixing seat 1, the screw die 3
Overall diameter be less than 1 cannula structure of screw die fixing seat interior diameter, be fastenedly connected by screw die fixing bolt 2, the screw die 3
Card slot is provided on outer end face, card slot and screw die fixing bolt 2 cooperate.
When in use, this tooling is mounted on lathe tailstock first, secondly workpiece one end is clamped on lathe chuck,
Finally the workpiece other end is put in the screw die 3 of this tooling, rotating chuck, workpiece is rotated by chuck and connect with screw die 3, screw die
3 automatically adjust with the power of workpiece, are in workpiece and screw die 3 on a center line, want to reach accuracy of thread and meet design
It asks, workpiece bows is avoided to deform, and then improve working efficiency.
Claims (2)
