Description
Technical field
The utility model relates to a kind of hydraulic pressure multiloop But rotary joint.
Background technique
The therefore accurate positioning of machine tool hydraulic fixture, clamping is used widely fast, thus causes oil feed line in lathe assorted many, the hidden danger that there is hydraulic fluid leak and mutually gang up.
Model utility content
The utility model makes improvement for above-mentioned prior art Problems existing, namely technical problem to be solved in the utility model is to provide a kind of hydraulic pressure multiloop But rotary joint, ensure, successively to fixture conveying liquid force feed, hydraulic fluid leak can be prevented again and mutually gang up.
In order to solve the problems of the technologies described above, the technical solution of the utility model is: a kind of hydraulic pressure multiloop But rotary joint, comprise one and be arranged on rotating shaft on lathe, one end sidewall of described rotating shaft is arranged at intervals with several annular grooves, described annular groove external application bearing housing is provided with axle sleeve, the seal ring of isolating each annular groove is provided with in described axle sleeve, described side wall of shaft sleeve is provided with the oil hole that quantity is equal with annular groove quantity, described oil hole is connecting fluid pressuring oil pipe respectively, the other end of described rotating shaft is connected with hydraulic fixture, the quantity through hole equal with annular groove quantity is provided with vertically in described rotating shaft, one end of a described annular groove difference UNICOM through hole, the other end of described through hole is connected with hydraulic fixture and is hydraulic fixture fuel feeding.
Compared with prior art, the utility model has following beneficial effect: this device, by the built-in oil circuit of rotating shaft, namely ensures, successively to fixture conveying liquid force feed, can prevent again hydraulic fluid leak and mutually gang up; And by group oil circuits many in rotating shaft for machine tool chief axis hydraulic fixture; The maximum speed of rotating shaft simultaneously reaches 2000RPM, and hydrodynamic pressure can reach 7MPa/mm
3.
Below in conjunction with the drawings and specific embodiments, the utility model is described in more detail.
Accompanying drawing explanation
Fig. 1 is the organigram of the utility model embodiment.
In figure: 1-rotating shaft, 11-through hole, 12-annular groove, 2-hydraulic fixture, 3-axle sleeve, 31-seal ring, 4-bearing, 5-hydraulic oil pipe.
Embodiment
Embodiment one: as shown in Figure 1, a kind of hydraulic pressure multiloop But rotary joint, comprise one and be arranged on rotating shaft 1 on lathe, one end sidewall of described rotating shaft 1 is arranged at intervals with several annular grooves 12, described annular groove 12 external application bearing 4 is arranged with axle sleeve 3, the seal ring 31 of isolating each annular groove is provided with in described axle sleeve 3, described axle sleeve 3 sidewall is provided with the quantity oil hole equal with annular groove quantity, described oil hole is connecting fluid pressuring oil pipe 5 respectively, the other end of described rotating shaft 1 is connected with hydraulic fixture 2, the quantity through hole equal with annular groove quantity 11 is provided with vertically in described rotating shaft 1, one end of a described annular groove 12 difference UNICOM through hole 11, the other end of described through hole 11 is connected with hydraulic fixture 2 and is hydraulic fixture fuel feeding.
During work, oil hydraulic cylinder is by carrying out oiling in the hydraulic oil pipe countershaft on axle sleeve, and during operation, rotation is told in rotating shaft, and axle sleeve does not turn, and hydraulic oil is injected in annular groove, then is injected in the through hole of connection separately respectively, to hydraulic fixture fuel feeding.
The foregoing is only preferred embodiment of the present utility model, all equalizations done according to the utility model claim change and modify, and all should belong to covering scope of the present utility model.
