Tenon mortise cutter for solid wood furniture

Abstract

A tenon mortise cutter for solid wood furniture includes a work piece positioning device and an eccentric cutting device. The work piece positioning device includes a work piece fixing mechanism, a tenon mortise length setting mechanism, and a tenon mortise center positioning mechanism. The eccentric cutting device includes a tenon mortise thickness and cutting mode setting mechanism, a caving machine fixing mechanism, and a rotation shaft sleeve. The work piece positioning device and the eccentric cutting device are connected together through the rotation shaft sleeve to work together, and then cutting and machining of a tenon and a mortise can be finished through linear motion and rotation motion.

Description

technical field [0001] The invention relates to an auxiliary tool for carpentry, in particular to an auxiliary tool for cutting tenons and mortises used in the process of making mortise and tenon structure furniture. Background technique [0002] In the process of making solid wood furniture, master carpenters often use the traditional mortise and tenon structure to connect wooden boards. The furniture with mortise and tenon structure is integrated, retro and beautiful. However, in the production process, the processing of the mortise and mortise is relatively complicated. The mortise and mortise need to be processed together, which requires high precision. The pure manual processing cycle is long and the efficiency is extremely low, so mass production cannot be realized. For large-scale industrial production, special automation equipment can be used for processing, but for single-piece production and small-batch production of handmade furniture, this special equipment is ex...

Problems solved by technology

However, in the production process, the processing of the mortise and mortise is more complicated. The mortise and mortise need to be processed together, which requires high precision. The pure manual processing cycle is long and the efficiency is extremely low. Mass production cannot be realized.

For large-scale industrial production, special automation equipment can be used for processing, but for single-piece production and small-batch production of handmade furniture, this special equipment is expensive and cannot meet the needs of small and medium-sized furniture factories and individual users.

At present, although there are square mortise machines that can realize the function of making square mortise (making square mortise with a saw), the processing process is complicated and cumbersome. Different processing equipment is required to process mortise and mortise. It cannot be formed at one time, and a special square tenon must be used. The drill bit can only be used when it is installed on the bench drill. The size of the mortise hole is limited by the square mortise drill bit, and the edge of the square mortise is removed by pressing down during the processing, which will damage the wood to a certain extent, and the processing accuracy is low and the efficiency is low.

In addition, there are several models that use engraving machines and molds to process tenon and mortise holes, but the processing size is limited by the mold during processing, and cannot be adjusted at will according to the thickness of the wood board and work needs, and can only rely on the size of the mold to process and fix the size. The mortise and mortise, and the processing of the paired mortise and mortise also needs to use two kinds of molds, and the mold and milling cutter should also be matched, which lacks versatility and flexibility
