Abstract

The invention relates to the field of a machining main shaft unit, in particular to a numerical control main shaft unit, which comprises a main shaft for bearing a machining tool, a hollow pull rod, a main shaft feed driving device for driving the main shaft to slide axially, a main shaft rotation driving device for driving the main shaft to rotate radially, and a box body. Compared with the prior art, the numerical control main shaft unit is mainly arranged on a machining device to perform machining operations of drilling, reaming, boring, tapping, and the like, the feeding speed of the main shaft is easy to control, the vibration is smaller when the machining is in place, the precision of the axial dimension in the process of machining a workpiece is easy to control, the surface finish quality of a machined workpiece is high, and wearing parts are easy to replace, thus the numerical control main shaft unit sufficiently meets the requirements of the modern machining.

Description

technical field [0001] The invention relates to the field of machining spindle units, in particular to a numerically controlled spindle unit. Background technique [0002] The spindle unit is mainly installed on mechanical processing equipment for drilling, reaming, boring, tapping and other mechanical processing. The traditional driving method is pneumatic or hydraulic drive, and the processing position limit method is mechanical limit. This kind of driving mode is single, which is prone to defects such as air leakage or oil leakage, the feed speed is not easy to control, the vibration is large when the machining is in place, the axial dimension accuracy is not easy to control when machining the workpiece, the surface finish of the processed workpiece is not high, and the wearing parts are not easy to replace . With the continuous development of the machinery industry, this traditional spindle unit can no longer meet the needs of the market. [0003] Although the CNC spin...
