Preparation process of semi-mortise and tenon joint structure at wooden product joint

Abstract

The invention discloses a preparation process of a semi-mortise and tenon joint structure at a wood product joint, and belongs to the technical field of mortise and tenon joint preparation. Accordingto the preparation process of the semi-mortise and tenon joint structure at the wood product joint, in the semi-mortise and tenon joint preparation process, through the arrangement of a straight faceball milling plate, wood flocks right facing the inner wall of the opening of a mortise can be effectively isolated and polished, so that the flatness of the inner wall of the mortise is effectively improved, the difficulty of polishing the inner wall of the mortise can be effectively reduced, and thus the preparation efficiency for the semi-mortise and tenon is effectively improved; and meanwhile, the wood flocks are compacted in the grinding process of a pressurizing friction ball, so that the gap between the residual fine wood flocks after grinding and the inner wall of the mortise is smaller, the flatness of the inner wall of the mortise can be effectively improved under the action of a flattening assisting glue layer, and meanwhile, the overall hardness and strength of the inner wallof the mortise can be effectively improved, so that the connection tightness between the tenon and the mortise is effectively improved, the semi-mortise and tenon joint is difficult to loosen, and theservice life is effectively prolonged.

Description

technical field [0001] The invention relates to the technical field of mortise and tenon preparation, and more specifically, relates to a process for preparing a half mortise and tenon structure at the joint of wood products. Background technique [0002] Mortise and tenon (sǔn mǎo) is the main structural method of ancient Chinese buildings, furniture and other appliances. It is a connection method that uses concave and convex parts on two components. The protruding part is called tenon (or tenon); the concave part is called tenon (or tenon, tenon and groove). Wood products are usually connected by tenon and tenon. Its characteristic is that no nails are used on objects, and mortise and tenon are used to reinforce objects, which reflects ancient Chinese culture and wisdom. [0003] Dozens of different "mortise and tenon" are classified according to their structure and can be roughly divided into three types: [0004] One type is mainly used for the joining of surfaces, and...

Problems solved by technology

[0007] The joints on the side of the picture frame mostly adopt the half-tenon connection method. Compared with the through-tenon, the mortise and tenon holes are not pierced, and the straight tenon is not exposed, so the tenon and tongue are generally two-thirds of the through-tenon. Since the mortise is not cut through, a lot of uneven wood shavings will remain on the inner wall during the preparation process, especially the inner wall facing the mouth of the mortise and mortise is more rough, resulting in the gap between the inner walls of the mortise and tenon after the half-mortise connection in the later stage. The connection is not tight enough, and there are gaps, which makes the connection on the side of the picture frame easy to loosen, which affects the service life of the picture frame
