Summary of the invention:
The utility model has overcome deficiency of the prior art, and a kind of good cooling results is provided, and noise is low, and is reliable and stable, inside and outside two cold high-speed electric main shafts that precision is high.
In order to solve the problems of the technologies described above, the utility model is achieved through the following technical solutions:
A kind of inside and outside two cold high-speed electric main shafts are made up of rotating shaft, rotor, motor stator, sleeve etc., and the top and bottom of rotating shaft are provided with upper bearing (metal) and lower bearing respectively, and on upper bearing (metal) and lower bearing below sealing device is set respectively; The outside of rotating shaft is provided with rotor, and the outside of rotor is a motor stator, and sleeve is arranged on the outside of motor stator; Wherein, described rotating shaft has central through hole; Sleeve inner is provided with the cooling liquid runner; The rotating shaft top connects with high-speed joint, and high-speed joint communicates with the central through hole of rotating shaft.
In described inside and outside two cold high-speed electric main shafts, the quantity of cooling liquid runner is 1～6, circumferentially evenly distributes along sleeve.For making the cooling fluid cooling that can circulate, the inlet of cooling liquid runner can be connected with liquid feed device, and nozzle is set at the liquid outlet place of cooling liquid runner, cooling fluid in the liquid feed device sprays from nozzle after inlet enters the cooling liquid runner, continuation is cooled off workpiece and cutter, Pen Chu cooling fluid also can be got back to liquid feed device after by the filter of lathe simultaneously, realizes the circulation cooling to main shaft.
In addition, an external cooler can be set also, the output of this cooler and input connect with the inlet and the liquid outlet of cooling liquid runner respectively, form the peripheral passage with the cooling liquid runner, and cooling fluid can circulate in this path; Can be that series connection communicates between each cooling liquid runner in the path, also can be that parallel connection communicates; When parallel connection communicates, shunt is set, by regulating the choke valve in the shunt, each the cooled liquid stream channel temp equilibrium after can keeping shunting at the output of cooler.
Compared with prior art, the beneficial effects of the utility model are:
1. inside and outside two cold high-speed electric main shafts described in the utility model when liquid stream is taken away electric main shaft outside heat, can also guarantee that internal temperature is constant, and the inside and outside liquid cools that all adopts, and good cooling results, noise is low, reliable and stable, precision is high.
2. inside and outside two cold high-speed electric main shafts described in the utility model, the cooling fluid that flows out from electric main shaft has the function of cooling off cutter and workpiece simultaneously concurrently, can prolong the useful life of cutter, guarantees machining accuracy.
