The spiral dual-cooling-channel high speed motorized spindle is characterized in that the cooling water channels are arranged on between the shell and the sleeve as well as between the shell and the front bearing pedestal, the two sets of cooling water channels with cooling liquid convective are arranged, and the water channels are both spiral and arranged on the inner surface of the shell and the outer surface of the front bearing pedestal. A water inlet of one cooling water channel and a water outlet of the other cooling water channel are formed in the front end of the motorized spindle, and a water outlet and a water inlet which correspond to the two sets of cooling water channels are formed in the rear end of the motorized spindle. According to the motorized spindle, the cooling liquid in the two sets of cooling water channels cools the motorized spindle in a convection mode, it is guaranteed that the overall temperature of the motorized spindle is constant, and the cooling effect is good.
Description
Technical field
The utility model relates to two cooling ducts high-speed electric main shaft, refers in particular to a kind of high-speed electric main shaft that screw type two water inlets pair go out water cooling passageway that has.
Background technology
High-speed Electrical Spindle application is very extensive, relates to the field that machine industry, electronics processing industry, Mould Machining industry etc. need High Rotation Speed, High-speed machining.The electricity integrated main shaft of main shaft and motor, the high volume of rotating speed is little, produces a large amount of heat during running, can not get cooling and there will be motor temperature too high, even burns out a bearing.
During the work of electricity main shaft, cooling water constantly flows in cooling water channel, the heat of built-in motor and bearing is taken away, but the jacket structure for water adopting mostly at present is one-way flow, i.e. delivery port of a water inlet, at electric spindle power with when load is less or rotating speed is lower, can keep electric main shaft internal temperature balance.Once add, load in man-hour is excessive or rotating speed is too high, single current is difficult to unnecessary heat to take away to the type of cooling, cause electric main shaft internal temperature to raise, main shaft near cooling water channel inlet end temperature lower than the other end, electricity main shaft diverse location operating temperature is inconsistent, make static characteristic and the dynamic characteristic variation of electric main shaft, affect the precision of electric main shaft, when serious, directly cause bearing to burn out.
Utility model content
The purpose of this utility model is to provide a kind of good cooling results, the two cooling ducts of the spiral High-speed Electrical Spindle that the inner temperature control of main shaft is stable.
The utility model solves the technical scheme that its technical problem adopts: the two cooling ducts of a kind of screw type high-speed electric main shaft, by rotating shaft, rotor, motor stator, axle sleeve, the compositions such as housing, the outside of rotating shaft is provided with rotor, the outside of rotor is motor stator, stator sleeve is located between stator and housing, on stator sleeve and front-end bearing pedestal, there is cooling water channel, it is characterized in that: cooling water channel is arranged at respectively between housing and sleeve and between housing and front-end bearing pedestal, the cooling water channel that has two groups of cooling fluid convection current, water channel is all located on shell inner surface and front-end bearing pedestal outer surface in the shape of a spiral.
Described electric front-end of spindle is established the water inlet of a cooling water channel and the delivery port of another cooling water channel, and electric rear-end of spindle is established two groups of delivery port and water inlets that cooling water channel is corresponding.The helix of two groups of cooling water channels is two helixes that are axially equally spaced.
The utility model has the advantages that: different from traditional cooling water channel, the utility model has two groups of cooling water channels, cooling effect is higher than the electric main shaft that only has one group of cooling water channel, temperature environment that can the work of more effective assurance main shaft; Cooling water channel water is convection type simultaneously, guarantee that main shaft diverse location temperature is more or less the same, preferably resolve the different problem of single cooling water channel main shaft bulk temperature, improved Spindle Static step response and dynamic characteristic, be the spindle vibration amplitude reduction in the process turning, precision improves; Cooling water channel is helical form, has reduced cooling fluid by the resistance of water channel, has increased area of dissipation, further improves cooling effect.
Accompanying drawing explanation
Below in conjunction with drawings and embodiments, the utility model is further illustrated.
Fig. 1 is structure chart of the present utility model.
Fig. 2 is schematic appearance of the present utility model.
Fig. 3 is water channel schematic diagram of the present utility model.
The specific embodiment
In electric main shaft, comprise the compositions such as rotating shaft 6, rotor 2, motor stator 3, axle sleeve 4, housing 8.The outside of rotating shaft is provided with rotor 2, the outside of rotor 2 is motor stators 3, stator sleeve 4 is located between stator 3 and housing 8, on stator sleeve 4 and front-end bearing pedestal 7, there is cooling water channel 5, cooling water channel 5 is arranged at respectively between housing 8 and sleeve 4 and between housing 8 and front-end bearing pedestal 7, the cooling water channel that has two groups of cooling fluid convection current, water channel is all located on shell inner surface and front-end bearing pedestal outer surface (as Fig. 3) in the shape of a spiral.On front-end bearing pedestal, on helical form cooling water channel 5003 and housing, helical form cooling water channel 5004 is the helix being axially equally spaced, electricity front-end of spindle is established the water inlet 5001 of cooling water channel one and the delivery port 5002 of another cooling water channel, and electric rear-end of spindle is established two groups of delivery port 5005 and water inlets 5006 that cooling water channel is corresponding.
It is vertical with the import and export line of rear end cooling water channel that the cooling water channel of electricity front-end of spindle is imported and exported line.Inject after cooling fluid, cooling fluid convection current in two cooling water channels, thus take away rapidly main shaft heat, and guarantee main shaft normal working temperature.Because cooling fluid is to be injected by two ends simultaneously, guarantee that main shaft bulk temperature is stabilized in the normal working temperature being more or less the same, and improves spindle rotation accuracy.
