Abstract
The present invention relates to a kind of expansion screw shop bolt, have including the pin sleeve with internal thread hole, on pin sleeve to first terminated before bottom end to longitudinal seam from top ends, first forms the first swollen portion between longitudinal seam；Pin sleeve has to second terminated before top ends to longitudinal seam from bottom end, and second forms the second swollen portion between longitudinal seam；Described first is along the circumferential direction interspersed to longitudinal seam compared with second to longitudinal seam.The expansion screw shop bolt of the present invention, the inner wall of pin sleeve is internal thread, during use using screw thread the angle of rifling and fixture bottom hole this pressure expanded pin swollen portion so that pin outer diameter is bonded pin hole inner wall, to reach the pin hole gap of pin and furniture or instrument wherein one side as zero.The precision of this fit system just depends on merely the dimensional uniformity with both sides pin hole, has avoided a series of problems during shaft hole matching.
Description
Technical field
The present invention relates to high position precision components, and in particular to the shop bolt applied on optical mirror plane.
Background technology
In optical component by taking common off-axis aspheric mirror as an example, cylindrical pins positioning and spiral shell are used in existing processing scheme
The installation way of bolt fastening.Cylindrical pins coordinate twice with fixture and workpiece respectively in use.It wherein needs to consider that installation is flat
Face fits closely and convenient to disassembly, reproducible, so can only be gap-matched.But conventional optics off-axis mirrors
Mostly using optics fine aluminium, and the material that fixture uses is also aluminium (considering the feasibility of jewel turning and the weight of fixture).This
Pin hole is resulted in, which to plug posteromedian column surface damage several times, makes gap fail, and limits the selection of fit clearance, usually 0.02~
0.03mm.Such positioning is inadequate for the speculum of some long-focus, so also needing other tune in practical operation
Whole means influence efficiency and the quality assurance of mass production.
The content of the invention
Work efficiency can be improved it is an object of the invention to overcome the deficiencies of the prior art and provide one kind and improves repetition
The expansion positioning pin nail of installation accuracy.
To achieve the above object of the invention, a kind of expansion screw shop bolt is provided, including the pin sleeve with internal thread hole,
Have on pin sleeve to first terminated before bottom end to longitudinal seam from top ends, adjacent first forms the between longitudinal seam
One swollen portion；Pin sleeve has to second terminated before top ends to longitudinal seam from bottom end, and adjacent second between longitudinal seam
Form the second swollen portion；Described first is along the circumferential direction interspersed to longitudinal seam compared with second to longitudinal seam.
Preferably, described first has the through hole along pin sleeve from outside to inside to longitudinal seam terminal；Described second is to vertical
There is the through hole along pin sleeve from outside to inside to seam terminal.
Preferably, including five first to longitudinal seam and five second to longitudinal seam.
The expansion screw shop bolt of the present invention, the inner wall of pin sleeve are internal thread, and the angle of rifling of screw thread is utilized during use
With the swollen portion of this pressure expanded pin of fixture bottom hole so that pin outer diameter is bonded pin hole inner wall, with reach pin and furniture or
The pin hole gap of instrument wherein one side is zero.The precision of this fit system just depends on merely consistent with the size of both sides pin hole
Property, avoid a series of problems during shaft hole matching.And simple pin hole dimensional uniformity can control μ grades, this
Advantageous effect of the invention is to greatly improve work efficiency and repeat the precision of installation.
Description of the drawings
Fig. 1 is the structure diagram of expansion screw shop bolt in the present invention；
Wherein：
1- pin sleeves 2- first is to longitudinal seam 3- second to longitudinal seam
First swollen the second swollen portions of portion 5- of 4-.
Specific embodiment
Below in conjunction with the drawings and specific embodiments, the present invention will be further described.
Expansion screw positioning screw according to figure 1 including the pin sleeve 1 with internal thread hole, has on pin sleeve 1
Longitudinal seam is longitudinally sewed with 1 outer wall of pin sleeve and is deep into inner wall, is longitudinally sewed with two groups, is to before bottom end respectively from top ends
First terminated is to longitudinal seam 2 and from bottom end to second terminated before top ends to longitudinal seam 3.Adjacent first is to vertical
The first swollen portion 4 is formed between seam 2, second forms the second swollen portion 5 between longitudinal seam 3, and swollen portion is used to expand.Share 5 first to
Longitudinal seam and 5 second are to longitudinal seam.First is along the circumferential direction interspersed to longitudinal seam compared with second to longitudinal seam.Make
One swollen 4 and second swollen portion 5 of portion is also interlaced.Described first has the through hole along pin sleeve from outside to inside to 2 terminal of longitudinal seam；
Described second has the through hole along pin sleeve from outside to inside to 3 terminal of longitudinal seam.Pupil is indulged for increasing stress when placing expansion
It is torn to seam.
Pin inner wall is internal thread, during use using bolt the angle of rifling and fixture bottom hole this pressure expanded pin bullet
Property structure so that pin outer diameter is bonded pin hole inner wall, to reach the pin hole gap of pin and fixture or workpiece wherein one side as zero.
The precision of this fit system just depends on merely the dimensional uniformity with both sides pin hole, has avoided a series of during shaft hole matching
Problem.And simple pin hole dimensional uniformity can control μ grades, greatly improve work efficiency and repeat the essence of installation
Degree.When in use, the size of expansion screw shop bolt follows the pin hole of smaller one side in workpiece or fixture.This fit system
Precision just depend on dimensional uniformity with both sides pin hole merely, avoided a series of problems during shaft hole matching.
The preferred embodiment of the invention is illustrated above, but the invention be not limited to it is described
Embodiment, those skilled in the art can also make a variety of etc. on the premise of without prejudice to the invention spirit
Same modification or replacement, these equivalent modifications or replacement are all contained in the application claim limited range.
