Self-lubricated machine tool spindle

Abstract

The invention relates to a self-lubricated machine tool spindle. The self-lubricated machine tool spindle comprises a spindle shaft body and a shaft sleeve, wherein the spindle shaft body is arranged in the shaft sleeve; two ends of the shaft sleeve are separately provided with an inner flange plate and an outer flange plate; each inner flange plate is connected with the corresponding outer flange plate in a sealed manner through an elastic sealing ring sleeve; a plurality of elastic devices are arranged in each sealing ring sleeve; two ends of each elastic device are separately fixedly connected with the corresponding inner flange plate and the corresponding outer flange plate; an oil inlet pipe is arranged between each outer flange plate and the spindle shaft body in a penetration manner; a plurality of holes are formed in the surface of the spindle shaft body; a sponge is arranged on the inner side of each hole; the outer side of each hole is provided with a filter net; a plurality of bumps are uniformly arranged on the inner side surface of the shaft sleeve; a temperature sensor is arranged between the spindle shaft body and the shaft sleeve; a controller and an alarming device are arranged on the outer side of the spindle shaft body; and the temperature sensor and the alarming device are separately connected with the controller. By adopting the self-lubricated machine tool spindle, the problems that the surface lubrication is not good; two ends of the spindle are easily impacted and damaged; and the spindle is easily burned due to overhigh temperature are solved.

Description

technical field [0001] The invention relates to a self-lubricating machine tool spindle, belonging to the technical field of machine tools. Background technique [0002] The machine tool spindle refers to the axis on the machine tool that drives the workpiece or tool to rotate. It is usually composed of main shaft, bearings and transmission parts (gear or pulley). mandrel. [1] Except for machine tools whose main motion is linear motion, such as planers and broaching machines, most machine tools have spindle components. The motion accuracy and structural rigidity of the spindle components are important factors that determine the processing quality and cutting efficiency. The indicators to measure the performance of spindle components are mainly rotation accuracy, stiffness and speed adaptability. ① Rotation accuracy: The radial and axial runouts that occur in the direction that affects the machining accuracy when the spindle rotates are mainly determined by the manufactur...
