Description

Изобретение относитс к клепальносборочным работам, в частности к способам получени заклепочного соединени с большим запасом прочности и надежности.The invention relates to riveting works, in particular, to methods for producing a rivet joint with a large margin of safety and reliability.

Извecteн способ получени заклепочного соединени путем установки заклепок в отверсти , по меньшей мере , одного р да плоскопараллельного пакета деталей, которые выполн ют под углом к его поверхности tl.A method has been developed for producing a rivet joint by installing rivets in the holes of at least one row of a plane-parallel package of parts that are made at an angle to its surface tl.

При этом отверсти одного р да включений в одной плоскости и отверстий , параллельных между собой.In this case, the holes of one row of inclusions in one plane and the holes parallel to each other.

Цель изобретени - обеспечение повышени надежности и прочности заклепочного соединени с глухими отверсти ми в пакете под заклепным, работающего под знакопеременными нагрузками .The purpose of the invention is to provide an increase in the reliability and strength of a rivet joint with blind holes in a package under riveted, operating under alternating loads.

Поставленна -цель достигаетс тем, что в способе получени заклепочного соединени путем установки заклепок в отверсти , по меньшей мере, одного р да плоскопараллельного пакета деталей , которые выполн ют под углом к его поверхности, отверсти дл двух смежных заклепок одного р да выполн ют под углом одно -относительно другого в противоположных направлени х, .The set target is achieved by the fact that in the method for producing a rivet joint by placing rivets in the holes of at least one row of a plane-parallel package of parts that are angled to its surface, the holes for two adjacent rivets of one row are angled one is relative to the other in opposite directions,.

Отв зсти дл смежных заклепок одного р да располагают в одной плоскости .The ridges for adjacent rivets of the same row are placed in the same plane.

Отверсти дл смежных заклепок од- ного р да располагсцот в разных плоскост х .The holes for adjacent rivets of one row are located in different planes.

На фнг.1 показан плоскопараллельный пакет деталей с заклепками с потайной закладной головкой, установленных в отверсти х двух смежных заклепок , выполненных в одном р ду, в разных направлени х и под углом одна относительно другой; на фиг.2 - то же, заклепки с закладными полукруглыми головками) на фиг.З - заклепочное соединение, отверсти одного р да лежат в одной плоскости, вид сверху; на фиг.4 - то же, отверсти выполнены под углом одно относительного другого , лежат в разных плоскост х, вид сверху; на фиг.5 - то же, со стержневыми заклепксми.Fig. 1 shows a plane-parallel package of parts with rivets with a concealed inset head installed in the holes of two adjacent rivets made in the same row, in different directions and at an angle relative to one another; 2 - the same, rivets with embedded semicircular heads) in FIG. 3 - a riveted joint, the holes of one row and yes lie in the same plane, top view; 4 is the same, the holes are made at an angle relative to one another, lie in different planes, top view; figure 5 - the same, with rod zaklepksmi.

Способ выполн етс следующим образом .The method is as follows.

Claims

In the assembled plane-parallel package of parts 1 and 2, holes are made at an angle "L" to the surface of the package. The optimum angles of inclination from 45 to 80 are chosen from the strength conditions and the manufacturability of the joints. The rivets 3 are inserted into the holes and fastened. The fastening of the rivet is made by known methods using expanding inlays or upsetting. At the same time, the pair and the group of rivets form a single brimming, replacing the load of different directions. When loading parts, (Fig. 1), rivet 3 is acted upon by force F, which can be decomposed into two inserts: FI — rivet 3 directed along the rod and F .j — perpendicularly Axis of the rod tending to press the rod to the wall holes. In this case, each of the rivets takes the load most well, which is directed along the axis of the rivet into the package and compresses it. Together, rivets perceive loads acting in opposite directions. With a load aimed at tearing the rivet head (Fig. 2), the force Q acting on the rivet head can be decomposed into the component forces 0. and Qr ;. The force Q acts along the axis of the rod and tends to pull the rivet out of the hole. Compared with conventional rivets (perpendicular to the package surface), this force is smaller and amounts to Qi (l -5 i nd. The force urj is perpendicular to the axis of the hole and presses it against the wall of the hole, increasing; adhesion. strength to the main; loads aimed at shear parts, the plane of location: the holes for the rivets are placed in the direction of these loads. The angles of inclination of the holes. 4). For packages that operate under difficult conditions when exposed to different loads, it is preferable to arrange holes for Kleckr in different planes. For a package of parts affected by loads of one direction The rivets are positioned in the direction of these loads. The connection can be made with rivets, and with riveted heads and rod rivets. with the corners of the connections 60-80 bending axis of the head is carried out directly by riveting. When riveting rod rivets (Fig. 3), they are installed in the blind hole of the bag and fixed in it. Then, the protruding rod of the rivet is bent away from the position perpendicular to the surface of the bag, and they form a closing head. These operations are carried out in any known manner using a riveting hammer or press. In the proposed method of joining parts by placing rivets at an angle to the package surface, as compared with the known, the speech area of the rivet working for shearing is increased. In addition, the axial force for tearing the rivet is reduced and its grip with the parts being joined is increased. All this leads to an increase in the strength and reliability of the joint compared to conventional rivet setting. Claim 1. A method for producing a rivet joint by installing rivets in the holes of at least one row of plane-parallel package of parts that are angled to its surface, characterized in that, with a chain to increase the reliability and strength of the joint, the holes of adjacent rivets of one row are made at an angle to one another in opposite directions.

2. A method according to claim 1, characterized in that the holes for adjacent rivets of one row are arranged in one plane.

3. Method 1, characterized in that the holes for adjacent rivets of one row are located in different planes. Sources of information taken into account in the examination 1. USSR author's certificate in application No. 2734141, cl. B 21 J15 / 50, 1979 (prototype).
