Tenon tongue cutting device for processing tenon joint

Abstract

The invention relates to a tenon tongue cutting device for processing a tenon joint. The tenon tongue cutting device comprises a bottom plate, wherein a support frame is arranged on the right upper side of the bottom plate; a motor is fixedly installed at the upper end of the support frame; a driving bevel gear sleeves a shaft of the motor in a matching manner; an arch-shaped frame is fixed to the left end surface of the support frame; a rotary shaft vertically penetrates through the arch-shaped frame and is separated from the arch-shaped frame by a bearing; a driven bevel gear which is meshed with the driving bevel gear is fixed at the middle part of the rotary shaft; the upper and lower end parts of the arch-shaped frame are both connected with an inclined fixing plate in a hinging manner; and a transmission shaft with a rotary axial line perpendicular to the corresponding inclined fixing plate is installed in the corresponding inclined fixing plate. Compared with the traditional processing mode, with adoption of a sawing disc sawing mode, the tenon tongue cutting device is beneficial to ensuring an inclination of a tenon tongue so as to effectively improve the processing accuracy and also keeps wastes with large size so as to prevent large-area environmental pollution and alleviate the treating difficulty of the wastes.

Description

technical field [0001] The invention relates to the technical field of wooden furniture processing equipment, in particular to a tongue cutting device for processing tenon joints. Background technique [0002] Mahogany furniture (English name: Rosewood Furniture) began in the Ming Dynasty. Its appearance is simple and symmetrical, and its natural material color and texture are pleasant. Mahogany mainly adopts traditional crafts such as carving, mortise and tenon joints, inlays, and curves made in Chinese furniture. German scholar G. Ecke summarized the three basic rules for processing mahogany furniture in "Chinese Rosewood Furniture Illustration": do not use wooden dowels unless absolutely necessary ; Do not glue as much as possible where it can be avoided; do not use turning anywhere. That is, without any nails and adhesives. Therefore, the obvious ethnicity in the shape and craftsmanship of mahogany furniture is the most attractive part to many collectors. Many people ...

Problems solved by technology

In the processing of the tenon, the tenon shoulder is usually formed by grinding off all the wood at the outer end of the tenon shoulder or gradually punching it away, which not only increases the difficulty of processing, produces a large amount of wood chips, but also makes it difficult to grasp the inclination angle of the side of the tenon. Often results in difficult or loose assembly

The generated sawdust is fine and difficult to clean up
