Abstract
The utility model relates to a kind of guide blot fixed structures, belong to the technical field of Automobile Design and manufacture.The guide blot fixed structure of the utility model, including the first workpiece, second workpiece and guide blot, guide blot pass through the mounting hole of the first workpiece and second workpiece and are fastenedly connected the first workpiece and second workpiece；Guide blot includes nut, polished rod and guide frame, and nut is connect with polished rod, and one end on guide blot far from nut is arranged in guide frame, and guide frame is provided with guide thread on the outer wall with the cross section and guide frame that gradually decrease.Polished rod boss structure is changed to inclined-plane helicitic texture by the guide blot fixed structure of the utility model, can be realized good guiding, can be avoided the situation that bolt and workpiece block, and is conducive to assembly time to reduce, is improved production efficiency.
Description
Technical field
The utility model relates to the technical fields of Automobile Design and manufacture, and more specifically, the utility model relates to one kind
Guide blot fixed structure.
Background technique
In the prior art, bolt front end guide frame is generally polished rod boss structure.As shown in Figure 1, in assembling process
In, bolt is installed along arrow direction shown in Fig. 2, since the mounting hole of the first workpiece 1 and second workpiece 2 is not often coaxial,
To which hole location bias conditions as Figure 2-3 can be generated.Since bolt front end is polished rod boss structure, the spiral shell in assembling process
Bolt boss position is easily blocked with the first workpiece 1, to can not be successfully across mounting hole, is needed to the first workpiece 1 and second workpiece 2
It adjusts repeatedly, to achieve the purpose that smoothly to assemble, greatly wastes assembly time in the process, influence production efficiency.
Utility model content
In order to solve above-mentioned technical problem in the prior art, the purpose of this utility model is to provide a kind of guide blots
Fixed structure.
A kind of guide blot fixed structure, including the first workpiece, second workpiece and guide blot, the guide blot pass through
First workpiece and second workpiece are simultaneously fastenedly connected by the mounting hole of first workpiece and second workpiece；It is characterized by:
The guide blot includes nut, polished rod and guide frame, and the nut is connect with polished rod, and the guide frame is arranged in institute
One end on guide blot far from the nut is stated, the guide frame has the cross section gradually decreased and the guiding is tied
Guide thread is provided on the outer wall of structure.
Wherein, it is additionally provided between the polished rod and guide frame with externally threaded threaded rod.
Compared with prior art, the guide blot fixed structure of the utility model has the advantages that
Polished rod boss structure is changed to inclined-plane helicitic texture by the guide blot fixed structure of the utility model, can be realized good
Good guiding, can be avoided the situation that bolt and workpiece block, and is conducive to assembly time to reduce, improves production efficiency.

Specific embodiment
It is further elaborated below with reference to guide blot fixed structure of the specific embodiment to the utility model, with side
Those skilled in the art is helped to have more complete, accurate and deep reason to the utility model design of the utility model, technical solution
Solution.
Embodiment 1
As shown in figure 4, the guide blot fixed structure of the present embodiment is led, including the first workpiece 10, second workpiece 20 and lead
To bolt 30.The guide blot 30 passes through the mounting hole of first workpiece 10 and second workpiece 20 and will be described by nut
First workpiece 10 and second workpiece 20 are fastenedly connected.The guide blot 30 includes nut 31, polished rod 32 and guide frame 35.Institute
Nut 31 is stated to connect with polished rod 32, and one end on guide blot far from nut 31, guide frame 35 is arranged in guide frame 35
Guide thread is provided on outer wall with the cross section and guide frame that gradually decrease.Between polished rod 32 and guide frame 35
Be additionally provided with externally threaded threaded rod 33, the threaded rod 33 by cooperating with nut so as to by the first workpiece 10 and
Second workpiece 20 fastens.
As shown in figure 5, guide part is changed to by boss as inclined-plane helicitic texture by the guide blot fixed structure of the present embodiment,
In workpiece dislocation, using the frictional force of helicitic texture and inner wall of the hole installing, bolt is screwed, on the one hand in bolt installation direction (Y
To) axial force is generated, on the other hand due to ramp effect, radial force is generated at (X to), makes the first workpiece 10 and second workpiece 20
Mounting hole is able to coaxially, so that bolt passes through mounting hole.The guide blot fixed structure of the present embodiment, which avoids, to be assembled
Shi Fanfu adjusts the first workpiece 10 and second workpiece 20 to meet the case where assembling, to reduce assembly time, improves
Production efficiency, and can reach and be easily assembled.
For the ordinary skill in the art, specific embodiment has only carried out exemplary retouch to the utility model
It states, it is clear that the utility model specific implementation is not subject to the restrictions described above, as long as using the method concept of the utility model
The improvement of the various unsubstantialities carried out with technical solution, or the not improved conception and technical scheme by the utility model are direct
Applied to other occasions, it both is within the protection scope of the present invention.
Claims (2)
1. a kind of guide blot fixed structure, including the first workpiece, second workpiece and guide blot, the guide blot passes through institute
