Abstract
The invention aims to provide a precision outer-diameter inner-circle positioning bolt. The precision outer-diameter inner-circle positioning bolt comprises a nut, an outer-diameter positioning part, a bolt connecting part, and an inner-diameter positioning hole. The precision outer-diameter inner-circle positioning bolt is capable of accurately positioning the location of the bolt through the outer-diameter inner-circle, correcting the transformation of the thread produced in the bolt connection, and guaranteeing the precision position relation of the connection members.
Description
Technical field
The design relates to a kind of accurate external diameter inner circle positioning screwn, belongs to precision machinery technology field.
Background technique
Screw is generally used for the connection of two component, in general mechanical connection, if it is not high to connect required precision, there is no need to connect screw accurately to locate.But due in screw connection, screw thread can produce distortion, and therefore, the position relationship of link can produce variation, in the precision optical machinery of ask for something precision positioning, this variation is unallowed, therefore, carrying out auxiliary precision positioning to attachment screw, to ensure to connect precision, is very necessary.
Summary of the invention
According to above-mentioned requirements, the object of the design is to provide a kind of accurate external diameter inner circle positioning screwn, is accurately located by the position of external diameter inner circle to screw, to correct the issuable distortion of screw thread in screw connection, ensures the precise positional relationship of connected element.
For achieving the above object, the design is realized by following technological means:
A kind of accurate external diameter inner circle positioning screwn, is characterized in that: comprise nut, external diameter positioning part, screw connection portion, internal diameter positioning hole.
Preferred:
Described one accurate external diameter inner circle positioning screwn, is characterized in that: the diameter of described internal diameter positioning hole is 1/3rd of described screw connection portion diameter.
Described one accurate external diameter inner circle positioning screwn, is characterized in that: the diameter of described screw connection portion is 4/5ths of described external diameter positioning part diameter.
Described one accurate external diameter inner circle positioning screwn, is characterized in that: the roughness of described external diameter positioning part is less than the roughness of described internal diameter positioning hole.
Described one accurate external diameter inner circle positioning screwn, is characterized in that: the length of described screw connection portion is 2 times of described external diameter positioning part length.
Described one accurate external diameter inner circle positioning screwn, is characterized in that: described nut is provided with cross fastening structure.
The invention has the beneficial effects as follows: the object of the design is to provide a kind of accurate external diameter inner circle positioning screwn, accurately located by the position of external diameter inner circle to screw, to correct the issuable distortion of screw thread in screw connection, ensure the precise positional relationship of connected element.
