The invention discloses a detachable lathe electric spindle with an air blowing device and a built-in rotor, comprising a machine body, a spindle and a rotor part, wherein a front cover inner ring, a front cover outer ring, a front bearing component, a rotor bushing, a back bearing seat, a back bearing component, a magnetic tent coder and a angling cylinder connection sleeve are arranged on the spindle in turn from left to right; the front cover inner ring is arranged in the left interior of the front cover outer ring; the end cover inner ring is sleeved on the front bearing component; an end cover outer ring is sleeved on the end cover inner ring; an air cock is arranged on the outer circle of the end cover outer ring; the rotor part is sleeved on the rotor bushing; a stator part is sleeved on the rotor part; a water jacket is sleeved on the stator part; a balance ring is sleeved on one end of the rotor bushing; the back bearing component is arranged in the back bearing seat; and a back cover is arranged on the end surface of the back bearing seat. The detachable lathe electric spindle has rational structure, is convenient to maintain, improves rotation precision of the spindle, prolongs service life and effectively prevents cooling liquid and metal powder from entering the interior of the lathe.
Description
Technical field: [0001] The invention relates to a lathe electric spindle technology, in particular to a lathe electric spindle with a detachable built-in rotor of a blowing device. Background technique: [0002] The electric spindle of a lathe is a highly technical mechatronics product, which is mainly installed on lathes and numerical control lathes, and is used in the machining industry of parts and components. After years of development of equipment in the lathe processing industry, as well as changes in the requirements of complex processing of parts, including the requirements for higher and higher processing accuracy of parts, this makes the original mechanical spindle of lathes that use belt gear rotation pairs unable to meet the conditions of use ; The electric spindle of the lathe combines the mechanical spindle of the lathe and the AC servo motor shaft into one, that is, the stator and rotor of the spindle motor are directly installed inside the spindle assembly, and a...
