Drilling equipment used in wood processing

Abstract

The invention belongs to the technical field of wood drilling, and in particular relates to a drilling device used in wood processing, which includes a drill tube module and a percussion drill body, wherein the drill tube module is detachably mounted on the output shaft of the percussion drill body; the present invention After the drill tube is stuck, the internal wood is crushed by the internal impact rod to restore the ability of the drill tube to continue drilling, ensuring that the inner wall of the drilled round hole is smooth and has no damage, and has a good anti-jamming effect. Two groups of four impact rods located in the surroundings designed by the present invention form two parallelogram structures. Under the action of the parallelogram, the mutually symmetrical two impact rods move alternately one after the other and the amplitude of the alternating motion is the same, ensuring the impact force It can be evenly transmitted to the wood through the two striking rods, which prevents the generation of impact bias force. In addition, during the movement, the centerlines of the two symmetrical striking rods are parallel to the center line of the middle striking rod. This design can improve the impact effect .

Description

[0001] Technical field [0002] The invention belongs to the technical field of wood drilling, in particular to a drilling device used in wood processing. Background technique [0003] Wood is a natural green environmental protection material, suitable for all kinds of decoration styles. It is what people pursue to have a healthy, green and comfortable living environment; and wood products have the following advantages: [0004] First, precious wood will form a unique and beautiful texture due to differences in climate, soil and tree species in the natural growth environment. After careful design and processing, it is beautiful. [0005] Second, wood is a naturally porous material; therefore, wooden doors have good sound insulation. It is not difficult for friends who like wooden furniture to find that their residence has less echo and better sound insulation. This kind of living space can give people a comfortable and quiet feeling. [0006] Third, natural wood will give...

Problems solved by technology

[0008] In the process of wood processing, the processing of large round holes is often involved, and cylindrical drills are generally used; because during the processing of cylindrical drills, the inner and outer circular surfaces of the drill are subject to greater friction, so the drill is prone to jamming In the current situation, one of the current technologies is to increase the power of the percussion drill body, which will increase the cost; the other is to tap and exit, which will damage the hole wall during the exit process and affect the quality of the formed hole.
