Abstract

The invention discloses a combined tenon-groove mechanism adapted to various shapes of slotted holes. The combined tenon-groove mechanism includes a rectangular frame body, a horizontal sliding bar isfixed to the surface of the rectangular frame body through supporting hanging lugs, the horizontal sliding bar is connected with a vertical sliding bar through a first rectangular sliding block,the vertical sliding bar is connected with a rotary bar through a second rectangular sliding block, and the rotary bar is fixedly connected with a moving drive shaft through a third rectangular sliding block; the rotary bar is provided with a first straight sliding slot, the first straight sliding slot is connected with a second straight sliding slot of a milling supporting rod through rotary plungers,the second straight sliding slot is provided with cylindrical sliding blocks, and the moving drive shaft and the cylindrical sliding blocksare arranged in a groove bodyshaped like a Chinese character'tian'; and the milling supporting rod is fixedly connected with a milling motor, a three-jaw fixture and a milling cutter head.The invention further provides a corresponding tongue-groove method. The combined tenon-groove mechanism enables the milling cutter head to run according to a rectangular, circular or elliptical trajectory of a specific size through motion conversion so that various precise tongue-groove structures can be milled, and an existing tenon-groove method of relying on artificial experience is greatly improved.

Description

technical field [0001] The invention relates to the technical field of furniture processing, in particular to a combined tongue-and-groove mechanism and a tongue-and-groove method adapted to slot holes of various shapes. Background technique [0002] The construction principle of the tenon and groove technology is to use several wooden strips processed by unique technology, without external auxiliary conditions such as nails, riveting and any adhesives or any means, but to use the mutual combination of the tenon and groove itself to form wood from different angles. And different directions can show different shapes of wooden tenon and groove handicrafts. With the continuous improvement of people's living standards, furniture with tongue and groove structure is very popular in the market. [0003] Existing mortise and groove technology uses mortise and groove machining to process the relatively simple shape of the groove body and tenon structure, and other more complex right...
