The invention discloses a drilling device for a composite material. The drilling device comprises a drill bit, a drill bushing, and a dust suction device, wherein a cutting part is arranged at the front end of the drill bit, the drill bit is provided with a chip removal inner cavity, the chip removal inner cavity communicates with the outside at the front end of the drill bit, and a through hole communicating with the chip removal inner cavity is formed in the side wall of the drill bit; the drill bushing is arranged on the drill bit in a sleeving mode, the drill bushing is rotatably connectedwith the drill bit, and the rotary joint of the drill bushing and the drill bit is located above the through hole; and the dust suction device communicates with an inner cavity of the drill bushing through a dust suction pipe. The drilling device for the composite material is simple in structure and convenient to operate, achieves automatic chip removal in the drilling process, prevents residualchips from scratching the hole wall, does not need staged shutdown chip removal, improves the machining efficiency effectively, and solves the problem that when an existing drilling device is used forcomposite material drilling, automatic chip removal cannot be achieved, the hole wall is prone to scratch, and the machining efficiency is low.
Description
technical field [0001] The invention relates to the technical field of hole making and processing for composite materials, in particular to a drilling device for composite materials with a laminated structure that integrates automatic chip removal, temperature reduction, and deviation correction functions. Background technique [0002] With the continuous development of the mechanization process, the application of machine tools is becoming more and more extensive, but at the same time, higher and higher requirements are put forward for the machining accuracy and efficiency of machine tools. Among them, the hole making process is one of the most common processing technologies in mechanical processing, and the drill bit is the most commonly used processing tool for making holes in workpieces, and it is widely used in machinery manufacturing and assembly departments. [0003] When traditional drills process composite materials, especially composite materials with laminated str...
