Abstract
The invention relates to a fastening method for the bolt group connection, belonging to the fastening method for the bolt connection and aiming to ensure the consistence of the pre-tightening force of all bolts in a bolt group, the uniformity of the distribution of contact pressure on the bolt combination surfaces, the reliability and the overall intensity. According to one scheme, two bolts in the middle part of each rectangular bolt combination surface are tightened and then all the left bolts are spirally tightened outwards in sequence from the centers of the rectangular bolt combination surfaces, or the two bolts in the middle part of each rectangular bolt combination surface are tightened and then all the left bolts are diagonally and symmetrically tightened from inside to outside in sequence relative to the central lines on the width direction of the rectangular bolt combination surfaces. According to the other scheme, two bolts on one central line of round bolt combination surfaces are tightened, then two bolts on the other central line are tightened, and finally all the left bolts are symmetrically tightened in sequence relative to the centers of the round bolt combination surfaces. The fastening method is used for the fastening of the bolt group connection.
Description
Technical field
The present invention relates to a kind of fastening method of Bolt Connection.
Background technology
In the bolt group connects; The uniformity of each bolt pretightening will directly influence the uniformity that contact pressure distributes on the bolt joint surface; And then the reliability and the intensity of influence connection, and up to now, in the bolt group connects; Do not have the uniformity that efficient ways guarantees that the contact pressure of bolt joint surface distributes and the reliability of connection, make the bulk strength of coupling part to guarantee.
Summary of the invention
The present invention is for guaranteeing the uniformity of each bolt pretightening in the bolt group, the uniformity that contact pressure distributes on the bolt joint surface and the reliability of connection and the bulk strength that guarantees coupling part, and then the fastening method that provides a kind of bolt group to connect.
The present invention addresses the above problem the technical scheme of taking to have two, is respectively:
Scheme one: the fastening method that bolt group of the present invention connects, the bolt joint surface in the said method be shaped as rectangle, said method realizes according to the following steps:
Step 1: processing bolt hole; Position near two long limits on the rectangle bolt joint surface is processed with a plurality of bolts hole, and a bolt is housed in each bolt hole, and the bolt combination that is contained in each bolt hole constitutes the bolt group together;
Step 2: said bolt component is screwed to the pretightning force of regulation for 2～4 times; The order that the bolt group is tightened each time is: after will being positioned at two bolts in the middle of the rectangle bolt joint surface earlier and tightening, outwards tighten each remaining bolt more twist successively from the center of rectangle bolt joint surface; Or after will being positioned at two bolts in the middle of the rectangle bolt joint surface earlier and tightening, again with respect to the center line symmetry of rectangle bolt joint surface width and be cornerwise form and successively the bolt of remainder tightened from the inside to the outside.
Scheme two: the fastening method that bolt group of the present invention connects, the bolt joint surface in the said method be shaped as circle, said method realizes according to the following steps:
Step 1: processing bolt hole; On circular bolt joint surface, be uniformly distributed with and be processed with a plurality of bolts hole, and four bolts hole in a plurality of bolt hole are arranged on the cross center line of circular bolt joint surface, a bolt is housed in each bolt hole and constitutes the bolt group near outer peripheral position;
Step 2: said bolt component is screwed to the pretightning force of regulation for 2～4 times; The order that the bolt group is tightened each time is: earlier two bolts on the center line in the cross center line of circular bolt joint surface are tightened; Again two bolts on another center line in the cross center line of circular bolt joint surface are tightened, at last according to tighten remaining bolt successively with respect to the centrosymmetric mode of circular bolt joint surface.
Effect of the present invention is: adopt method of the present invention no matter be to bolt joint surface be rectangular sheet material or to bolt joint surface for circular flange etc.; Can both guarantee the uniformity of each bolt pretightening in the bolt group; The uniformity that contact pressure distributes on the bolt joint surface and the reliability of connection have improved the bulk strength of coupling part.
