Carbon fiber section material and mortise and tenon structural assembly of carbon fiber section material

Abstract

The embodiment of the invention provides plates and a mortise and tenon structural assembly comprising the plates. The mortise and tenon structural assembly comprises a first plate and a second plate,wherein a mortise is formed in the first plate, first accommodating areas protruding outwards are arranged at the joint of adjacent side walls of the mortise, a tenon is arranged on the second plate,and second accommodating areas recessed inwards are arranged at the joint of the tenon and the second plate. By arranging the containing areas on the plate, the tenon and the mortise machined in a milling mode can be tightly combined without gaps; and in addition, the plates and the mortise and tenon structural assembly comprising the plates are simple in structure, do not need screws for auxiliary fixation, and improve the stress capacity of the plates under the condition of not affecting the strength of material.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of material processing, and more specifically, the embodiments of the present invention relate to a plate and a mortise and tenon structure assembly comprising the plate. Background technique [0002] This section is intended to provide a background or context for implementations of the invention that are recited in the claims. The descriptions herein are not admitted to be prior art by inclusion in this section. [0003] The traditional mortise and tenon structure cannot be directly used to fix plates processed by CNC milling technology, because the plates processed by CNC milling technology will not have sharp corners, such as figure 1 as shown, figure 1 It consists of two plates, one of which has a mortise (the mortise is a rounded rectangle), and the other has a tenon (the joint between the tenon and the plate is rounded), because the milling cutter has a cylindrical cross-sec...

Problems solved by technology

[0003] The traditional mortise and tenon structure cannot be directly used to fix plates processed by CNC milling technology, because the plates processed by CNC milling technology will not have sharp corners, such as figure 1 as shown, figure 1 It consists of two plates, one of which has a mortise (the mortise is a rounded rectangle), and the other has a tenon (the joint between the tenon and the plate is rounded), because the milling cutter has a cylindrical cross-sectional shape, Therefore, there must be rounded corners at the inner corner joints of the mortise and tenon structure holes. Such a mortise and tenon structure will cause gaps in the plate connection, such as figure 2 As shown, the tight combination of mortise and tenon cannot be achieved
