Problems solved by technology

[0006] The use of carbon fiber composite cloth or chemical bonding agent on the contact surface of the mortise and mortise can help to improve the strength of the aluminum alloy mortise and tenon structure to a certain extent, but the effect is not very ideal under certain working conditions. For example, when The aluminum alloy mortise and tenon structure is used for the body frame of new energy vehicles, and when new energy vehicles drive on bumpy roads, the tenons are easy to loosen, fall off, and may even be damaged

Embodiment 1

[0036] Such as figure 1 and figure 2 As shown, a reinforced aluminum alloy mortise and tenon structure includes a mortise 3 arranged on the mortise body 1 integrally formed with the mortise body 1 and a mortise 3 which is arranged on the corresponding position of the mortise body 2 and is in phase with the tenon 3 . Matching mortise 6, the hole wall of mortise 6 is successively provided with alumina cermet composite material coating 601, tungsten carbide cermet composite material coating 602, on the wall corresponding to mortise 3 and mortise 6 The surface is successively provided with alumina cermet composite material coating 301 and tungsten carbide cermet composite material coating 302, and the tungsten carbide cermet composite material coating 602 of the mortise hole 6 and the tungsten carbide cermet composite material coating of the tenon 3 A chemical linker structure layer 7 is provided between the layers 302 .

[0037] In order to improve the strength of the aluminum...

Embodiment 2

[0041] The basic structure of this embodiment is the same as that of Embodiment 1, the difference is that, as image 3 and Figure 4 As shown, in this embodiment, the mortise head is composed of two parts, the tenon base 3a and the tenon point 3b, and the mortise hole is composed of two parts, the outer mortise hole 6a and the inner mortise hole 6b. The shape and size of the inner mortise hole 6b match the shape and size of the mortise tip 3b, so that the mortise head can be snapped into the mortise hole. In this embodiment, the cross-sectional shapes of the outer mortise hole 6 a and the inner mortise hole 6 b are both square, which means that the cross-sectional shape of the tenon base 3 a and the tenon tip 3 b is also square. In addition, the ratio of the side lengths of the outer shank 6a to the inner shank 6b is 1:10, and the ratio of the depth of the outer shank 6a to the inner shank 6b is 1:2. The present embodiment adopts this structural design, which helps to preven...

Abstract

The invention belongs to the technical field of aluminum alloy component connection, and particularly relates to an enhanced aluminum alloy mortise and tenon structure which comprises a tenon arranged on a tenon piece body and integrally formed with the tenon piece body and a mortise hole formed in the corresponding position of the mortise piece body and matched with the tenon. An aluminum oxide metal ceramic composite material coating and a tungsten carbide metal ceramic composite material coating are sequentially arranged on the inner surface of the mortise hole, and an aluminum oxide metal ceramic composite material coating and a tungsten carbide metal ceramic composite material coating are sequentially arranged on the face, corresponding to the mortise hole, of the tenon. And a chemical connecting agent structural layer is arranged between the tungsten carbide metal ceramic composite material coating of the mortise and the tungsten carbide metal ceramic composite material coating of the tenon. The strength of the aluminum alloy mortise and tenon structure is greatly improved, and the situations that the tenon is broken, the tenon is cut off, the root of the tenon shoulder is torn, the root of the mortise is torn, the wall of the mortise is cut off, and the wall of the mortise is snapped can be effectively prevented.

Description

technical field [0001] The invention belongs to the technical field of connection of aluminum alloy components, and in particular relates to a reinforced aluminum alloy mortise and tenon structure. Background technique [0002] Mortise and tenon structure usually refers to the connection method that the protruding part of one component and the concave part of another component are engaged with each other, so as to connect and fix the two components. The protruding part is called "mortise" or tenon. The matching recessed part is called "mortise" or mortise hole, mortise eye, mortise, tenon groove, and the component with "mortise" is also called tenon body, and the component with "mortise" is also called tenon. It is the body of the socket. According to the different materials for making components, the mortise and tenon structure can be divided into wooden tenon and tenon structure, stone tenon and tenon structure, plastic tenon and tenon structure, aluminum alloy tenon and ...
