Therefore, a kind of low cost height rotating speed is needed can to substitute the device of swivel joint for Horizontal electric main shaft hollow water outlet.
Summary of the invention
1, the technical problems to be solved in the utility model
In order to solve the low and problem that high-rotation speed rotary connector price is high of swivel joint rotating speed in prior art, the utility model provides a kind of high rotating speed to be again the device of a kind of contactless replacement swivel joint for Horizontal electric main shaft hollow water outlet of low cost simultaneously.
2, technical scheme
To achieve these goals, the utility model adopts following technical scheme:
Contactless replacement swivel joint is used for a device for Horizontal electric main shaft hollow water outlet, and described device comprises rotating shaft, hollow cooling chamber, drainage seat, air admission hole, inlet opening, bonnet, drain chamber, discharge chamber and copper sheathing; In described copper sheathing press-in drainage seat, copper sheathing and drainage seat interference fit; Air admission hole is threaded connection the top in drainage seat, bonnet is threaded connection and forms drain chamber on drainage seat, inlet opening is threaded connection on bonnet, and described shaft set is in the middle of drainage seat, and the gap formed with drainage seat is discharge chamber and hollow cooling chamber.
Further, described rotating shaft is sheathed in copper sheathing, has gap between copper sheathing and rotating shaft, and copper sheathing not exclusively directly contacts with rotating shaft.
Further, be provided with air flue in described drainage seat, described air flue is communicated with air admission hole and discharge chamber, and discharge chamber is communicated with drain chamber.
Further, the left end cylindrical of described bonnet has reverse thread device, stops water to flow into main shaft inner.
Further, during horizontal installation, described drain chamber is downward, and water is discharged from drain chamber.
Further, when rotating shaft rotates, air admission hole keeps ventilation open mode.
Operation principle of the present utility model: intake by inlet opening, enters in hollow cooling chamber chamber, thus enters rotating shaft endoporus and cooled, from front-end of spindle cooling cutter; When rotating shaft rotates, if there is water to enter in discharge chamber cavity, because air admission hole ventilation is often opened, the water in discharge chamber is discharged from drain chamber.
3, beneficial effect
Compared with having technology with reality, the utility model has following beneficial effect:
(1) the swivel joint of the prior art bearing because being equipped with about two, so cost is relatively high, and in device of the present utility model, part is numerically controlled lathe and achievable machine components entirely, so advantage of lower cost;
(2) swivel joint of the prior art because of self rotating speed restricted, be rotating shaft contact when being loaded on main shaft, thus limit the maximum speed of main shaft, and be contactless when device of the present utility model is used for main shaft, so rotating speed is decided by the rotating speed of main shaft own;
(3) swivel joint of the prior art is loaded on after on main shaft, and main axis inertia is increased, and during high speed, centrifugal force increases, and causes rotating shaft reduced stiffness; And device of the present utility model can not affect main shaft rigidity;
(4) when main shaft rotates, when hollow cooling chamber leads to cooling water, due to the reason of backend space part, some water may flow into rear end bearing, to this, except the reverse thread device devised on bonnet, increase secondary sealing gland in addition, by air admission hole air inlet, make axle and bonnet gap location form effective compression ring, stop water to flow into main shaft inner.
(5) device of the present utility model is practical, and performance is high, can effectively fill up domestic vacancy, and this type of electro spindle can be domesticized, and cost can far below abroad, but effect but can with quite external.
