Description
Technical field
The utility model is related to fastening positioning interconnection technique field, refers in particular to a kind of screw thread shop bolt.
Background technology
Fastener is exactly to fasten when two or more parts (or component) are fastenedly connected as an entirety to be used
A class machine components general name.Screw and pin are the most widely used two classes fasteners.Pin, is a kind of shape picture nail
The metal rod of son, is typically cone, has tip or the metal tingle on pinnacle.How rounded cross section is, for being inserted in parts
Make connection or fixation.
With being continually changing and develop using scope and use environment, more demands are it is also proposed to pin, especially
It is on the Function Extension of pin.The positioning of existing localization tool, fixing function are separately designed, used screw and pin point
Exclusive use is opened, between screw and pin the problem of existence position tolerance！Pin is first typically installed, screw when mounted can phase
The internal stress that mutually interference is produced, causes pin easily broken, screw thread is easily damaged.Pin emerge fixture core rod part it is easy
It is disconnected, change inconvenient.
Utility model content
The utility model provides a kind of spiral shell for being provided simultaneously with threaded connection and positioning function for problem of the prior art
Line shop bolt.
In order to solve the above-mentioned technical problem, the utility model is adopted the following technical scheme that：
A kind of screw thread shop bolt, includes integrally formed pin cap and pin rod, the pin rod include the first positioning bar segment,
Second positioning bar segment and be screwed bar segment, it is described be screwed bar segment located at the first positioning bar segment and the second positioning bar segment it
Between.
Wherein, it is additionally provided with empty avoiding bar segment between the pin cap and the first positioning bar segment, the diameter of empty avoiding bar segment is less than the
The diameter of a positioning rod section.
Further, the bottom of the second positioning bar segment is provided with the taper guide part for guiding.
It is preferred that, the cone angle of the taper guide part is 45 ° to 60 °.
Wherein, the pin cap, pin rod are in cylindrical type, and sell the external diameter that the external diameter of cap is more than pin rod.
Further, it is provided with interior hexagonal groove at the top of the pin cap.
The beneficial effects of the utility model：
A kind of screw thread shop bolt that the utility model is provided, integrates positioning, fixing function, improves positioning accurate
Degree；Pin rod is connected with pin cap, if pin is emerged, the part of clamp mould fractures, and replacing pin is more convenient, improves work
Efficiency.
Brief description of the drawings
Fig. 1 is a kind of structural representation of screw thread shop bolt of the utility model.
Reference in Fig. 1 includes：
1-pin positioning positioning bar segment of bar segment 3-the second of cap 2-the first
4-the bar segment that is screwed, 5-empty avoiding bar segment 6-taper guide part
7-interior hexagonal groove.
Embodiment
For the ease of the understanding of those skilled in the art, further is made to the utility model with reference to embodiment and accompanying drawing
Explanation, the content that embodiment is referred to not to it is of the present utility model limit.The utility model is carried out below in conjunction with accompanying drawing
Detailed description.
A kind of screw thread shop bolt provided by the utility model, includes integrally formed pin cap 1 and pin rod, the pin
Bar includes the first positioning bar segment 2, second positioning bar segment 3 and the bar segment 4 that is screwed, and the bar segment 4 that is screwed is determined located at first
Between the positioning bar segment 3 of bar segment 2 and second of position.When screw thread shop bolt is used for fixed jig, fixed jig typically has bottom plate
And die；The positioning that first positioning bar segment 2, the second positioning bar segment 3 is used between bottom plate and die, the bar segment that is screwed 4
For the connection that is screwed between bottom plate and die.The utility model integrates positioning, fixing function, improves positioning accurate
Degree.And pin cap is connected with pin rod, if pin is emerged, the part of die fractures, and replacing pin is more convenient, can have
Effect improves operating efficiency.
In the utility model, empty avoiding bar segment 5, empty avoiding bar segment are additionally provided between the positioning of pin cap 1 and first bar segment 2
5 diameter is less than the diameter of the first positioning bar segment 2.Empty avoiding bar segment 5 is provided with pin rod, fixed jig is inverted clear away waste
When, screw thread shop bolt is not fallen out, it is not necessary to fill screw thread shop bolt again, improves production efficiency.
Further, the bottom of the second positioning bar segment 3 is provided with the taper guide part 6 for guiding, so may be used
It is easy to pin rod to insert in pilot hole.It is preferred that, the cone angle of the taper guide part 6 is 45 ° to 60 °, can be prevented effectively from complete cone
Shape sharp and accidentally injure operator.
Wherein, the pin cap 1, pin rod are in cylindrical type, and sell the external diameter that the external diameter of cap 1 is more than pin rod.So as to ensure pin
After bar insertion pilot hole, pin cap 1 can be automatically positioned.
Further, the top of the pin cap 1 is provided with interior hexagonal groove 7.If screw thread shop bolt fractures, use
Inner hexagon spanner is caught in interior hexagonal groove 7, and then the screw thread shop bolt after fractureing is disassembled, and changes pin fast side
Just.
It is described above, only it is the utility model preferred embodiment, not makees any formal to the utility model
Limitation, although the utility model is disclosed as above with preferred embodiment, but is not limited to the utility model, any to be familiar with sheet
Technical professional, is not departing from the range of technical solutions of the utility model, is made when using the technology contents of the disclosure above
A little change or the equivalent embodiment for being modified to equivalent variations, as long as being without departing from technical solutions of the utility model content, foundation
The utility model technology refers to any simple modification, equivalent variations and the modification made to above example, belongs to this practicality
In the range of new technique scheme.
