Abstract

The invention discloses a numerical control precision micro-fine super-long deep hole drilling machine which comprises a workbench, a master control cabinet, a linear motor and a servo motor. An output shaft of the servo motor is provided with a drilling bit. The linear motor comprises a primary part installed on the master control cabinet and a secondary part where the servo motor is installed. The secondary part drives the servo motor to move so as to enable the drilling bit to stretch out or retract back above the workbench. The workbench comprises a lifting base and a workbench top arranged on the lifting base. A clamp for fixing a workpiece is installed on the workbench top. According to the numerical control precision micro-fine super-long deep hole drilling machine, the linear motor is used as a feeding power source of the drilling bit, intermediate transmission links such as a gear, a worm gear pair, a belt, a lead screw pair, a coupler and a clutch which are needed in an existing transmission chain from a motor used as a power source to a working component are abandoned, and rotational inertia, elastic deformation, a backlash, motion hysteresis, friction, vibration, noise and abrasion of the intermediate transmission links are avoided; the numerical control precision micro-fine super-long deep hole drilling machine is high in degree of automation, easy to operate, high in control precision, stable in motion, low in noise, long in service life, safe and reliable.

Description

technical field [0001] The invention is used in the field of numerical control drilling, and in particular relates to a numerical control precision micro-fine ultra-long deep hole drilling machine. Background technique [0002] In the machinery manufacturing industry, hole processing can be divided into two types: shallow hole processing and deep hole processing. Generally, a hole with an aspect ratio L / D<5 (L is the hole depth, D is the hole diameter) is called a shallow hole, and L / D Holes with >50 are called deep holes, and holes with L / D>100 are called ultra-deep holes. According to statistics, among the 29 manufacturing industries in my country, at least half have direct demand for deep hole processing technology and equipment, and more than one third have urgent demand. In recent years, with the development of aviation, aerospace and weapons industries and the diversity of market demands, there are more and more deep hole machining of new difficult-to-machine...
