Abstract

The invention discloses numerical control vibration deep-hole drilling and boring machining equipment, which is characterized by comprising a workpiece arranged on a machine tool body, a drill bit and a drill stem, wherein the workpiece is driven by a main motor to rotate; and the drill bit is driven by the motor to rotate along with the drill stem and is simultaneously driven by a servo reducing motor and a vibration motor to make numerical control feed movement and axial reciprocating vibration. By the deep-hole drilling and boring equipment, the functions of rotating the workpiece and the drill bit in a bidirectional mode and axial vibration drilling can be realized, the severe working conditions and the lubricating effect of a cutting area of the drill bit are improved, the cuttings are automatically controlled, the process range of the equipment is greatly widened, the machining precision indexes of the holes such as roundness and straightness are improved, and the hole machining quality and efficiency are improved further; and moreover, the problem of chip breakage and removal in the prior art is solved, the cuttings can be automatically separated, collected and conveyed, automation of the drilling process is realized, and the equipment can be widely applied to the field of machining of rotary deep-hole parts.

Description

technical field [0001] The invention belongs to the technical field of mechanical processing, and relates to a deep hole drilling and boring processing equipment, in particular to a numerical control vibration deep hole drilling and boring equipment, and also relates to a processing method of the numerical control vibration deep hole drilling and boring processing 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 ult...
