Abstract

The invention relates to the technical field of numerical control machine tools, in particular to a multifunctional telescopic servo waterwheel electric spindle. The multifunctional telescopic servo waterwheel electric spindle is waterproof, dustproof and sealed in a non-contact mode, and can rapidly and comprehensively cool heat of a cutter and a workpiece in the cutting machining process, so that the surface machining quality of the workpiece is improved, and the service life of the cutter is prolonged. The multifunctional telescopic servo waterwheel electric spindle comprises a sleeve, a spindle body, a stator and rotor assembly, an electric spindle encoder and a cooling system. A front bearing set and a rear bearing set are installed on the front portion and the rear portion of the spindle body respectively. The front bearing set, the rear bearing set, the sleeve and bearing end covers located at the two ends of the sleeve jointly form an integral sealing cavity. A waterproof coveris fixed to the spindle body and can rotate along with the spindle body. The waterproof cover and a front gland groove form a labyrinth type waterproof structure. An air sealing annular groove and alabyrinth type sealing groove are formed between the waterproof cover and a front gland. The cooling system comprises cooling liquid channels uniformly arranged on the sleeve and eight cooling nozzlesarranged on a box body.

Description

technical field [0001] The invention relates to the technical field of numerically controlled machine tools, in particular to a multifunctional retractable servo waterwheel electric spindle. Background technique [0002] As we all know, the electric spindle is an integral spindle unit with a high-speed motor built into the spindle box. The rotor of the motor drives the spindle to rotate together, realizing mechatronics. However, the traditional electric spindle is used at the front end of the spindle of the machine tool, and the bearings, stator and rotor inside are strictly required not to enter the water. [0003] Most of the servo water wheel spindles on the market are driven by external motors and transmission belts. The transmission structure is complex, it takes up a large volume, the stability is poor, the parts are easily broken, and it is troublesome to replace. The eddy current, the high-speed operation of the bearing and the frequent repeated expansion and contra...
