Lengthwise cutting device used for tenon cheek machining

Abstract

The invention relates to a lengthwise cutting device used for tenon cheek machining. The device comprises a bottom plate, wherein a lifting platform is fixed on the upper end face of the bottom plate, a transversely arranged U-shaped rack is fixedly arranged at the upper end of the lifting platform, a bearing block is fixedly arranged at each of the upper end face and the lower end face of the U-shaped rack, an axle is arranged in each bearing block, a driven wheel is fixedly arranged at the rear part of each axle, a saw blade is fixed on the rear end of each axle, a tensioning pillar capable of rotating relative to the U-shaped rack is arranged at each of the upper side and the lower side of the left part of the rear end face of the U-shaped rack, and a guide wheel which is arranged on the U-shaped rack and can rotate relative to the U-shaped rack is arranged at the left side of each tensioning pillar. According to the invention, a motor is used for driving two driven wheels on the U-shaped rack to rotate, so as to drive the saw blades respectively connected with the corresponding driven wheels to cut timber of the tenon shoulder part, thus forming the tenon cheek. The lengthwise cutting device is matched with a device used for cutting the side face of the tenon cheek for use, thus greatly improving the tenon machining efficiency.

Description

technical field [0001] The invention relates to the technical field of wooden furniture processing equipment, in particular to a longitudinal cutting device for tongue processing. 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 ...

AI Technical Summary

Problems solved by technology

The tenon is the part that fits with the mortise. The wood around the tenon is usually punched off by metal punching. It is difficult to guarantee the processing accuracy by using metal punching, and the production efficiency is low.

In modern production, milling machines are often used to make tenon shoulders. When making tenon shoulders in different orientations, it is necessary to constantly change the placement of wood, which affects the accuracy of wood positioning, which in turn affects the processing accuracy of wood, and is prone to assembly difficulties. It also increases the difficulty of wood processing
