The invention relates to a vibration generator for vibrating deep-hole drilling and boring equipment, comprising a vibrating shaft in a hollow structure and an offset type eccentric slide block mechanism, wherein one end of the vibrating shaft is provided with a cutter bar, and the other end is connected with a chip removal tube; and the offset type eccentric slide block mechanism is arranged above the vibrating shaft and connected with the vibrating shaft through a double-bar linkage mechanism. In the invention, the offset type eccentric slide block mechanism is adopted and driven by a servo drive motor to rotate, and the vibrating shaft is driven by the double-bar linkage mechanism hollowly sleeved on an eccentric shaft and an eccentric sleeve to reciprocate, thereby realizing the low-frequency axial vibration, reducing the chip removal resistance and solving the problem of poor chip removal during processing in the prior art; and in addition, the invention has the advantages of simple and compact structure and stable and reliable operation.
Description
technical field [0001] The invention belongs to the technical field of mechanical processing, and relates to a vibration generator, in particular to a vibration generator for deep hole vibration drilling and boring equipment. Background technique [0002] Deep hole processing is an important branch in the field of mechanical processing, and has a wide range of applications in defense industry, oil mining, aerospace, machine tools, automobiles and other industries. Deep hole processing is very different from turning and milling. In the process of deep hole processing, the cutting conditions of the drill bit are very harsh. The generation and discharge of chips are completed in a small semi-closed space, and the drill bit wears quickly. Chipping, breakage and chip clogging are prone to occur, especially in the processing of ultra-long and deep holes. Due to the long shank, low strength and poor rigidity, it is very easy for the drill to deviate and the quality of the processed...
