Problems solved by technology

[0002] The traditional drilling, milling and milling tool machine drives the pulley shaft through the rotation of the transmission shaft, and drives the drill bit below to process. The hole precision of the workpiece is low. One is because the motor itself has a large mechanical vibration, and the other is because of the friction and vibration between the workpiece and the drill. Large, generally above 20 microns of vibration and beating, there is no good support body and displacement force in the transmission, so the vibration of the drill bit and the workpiece and the concentricity of the drill clamp and the clamping bit are not accurate, and it is easy to get stuck or stalled and broken bits
Traditional machine tools directly affect the quality of the workpiece and the life of the drill bit, severely restricting the processing of high-precision products

Abstract

A superspeed micro hole tool drill device comprises a power spindle, a rotating spindle, a clamping head and a drill bit clamped through the clamping head. The power spindle drives the rotating spindle to rotate, and the rotating spindle drives the clamping head and the drill bit to move. The superspeed micro hole tool drill device further comprises a hollow lifting shaft and a supporting fixing sleeve, the lifting shaft is sleeved on the rotating spindle, the supporting fixing sleeve is sleeved on the lifting shaft, the lifting shaft is supported on the supporting fixing sleeve in an air floatation or liquid floatation or magnetic suspension mode, the rotating spindle is supported in the lifting shaft in the air floatation or liquid floatation or magnetic suspension mode, air pressure or hydraulic pressure or magnetic force in the supporting fixing sleeve is controlled according to the processing depth requirements so as to enable the lifting shaft to drive the rotating spindle to rise, and the rotating spindle drives the drill bit to perform rotation and vertical displacement processing. Vibration is small when the device is used for processing superfine holes, processing precision is high, and the service life of the drill bit can be prolonged.

Description

technical field [0001] The invention relates to a drilling, grinding and milling machine tool, in particular to an ultra-high-speed micro-hole tool drilling device. Background technique [0002] The traditional drilling, milling and milling tool machine drives the pulley shaft through the rotation of the transmission shaft, and drives the drill bit below to process. The hole precision of the workpiece is low. One is because the motor itself has a large mechanical vibration, and the other is because of the friction and vibration between the workpiece and the drill. Large, generally above 20 microns of vibration and beating, there is no good support body and displacement force in the transmission, so the vibration of the drill bit and the workpiece and the concentricity of the drill clamp and the clamping bit are not accurate, and it is easy to get stuck or stalled and broken bits. Traditional machine tools directly affect the quality of the workpiece and the life of the dril...
