Description
Technical field
The present invention relates to a kind of machine-tool spindle system, be specially a kind of high accuracy dynamic and static pressure axis system.
Background technology
The high-precision grinding process equipment of China is also unable to reach advanced international standard at present, and all of high-accuracy grinding adds
The whole dependence on import of construction equipment, especially some ultrahigh precision process equipments, always by western countries' blockade on new techniques, and limit out
Mouth is to China.Big to space flight, military project, little to automobile, machinery, more and more higher to the demand of high-precision grinding process equipment, and zero
The height of part processing precision of products directly affects the serviceability of filled engineering goods and stability and service life.
Summary of the invention
It is an object of the invention to overcome the deficiencies in the prior art, it is provided that a kind of high accuracy dynamic and static pressure axis system, there is knot
The advantages such as structure is simple, parts are few, good, the superhigh precision of structural stability, are used for solving main shaft system in existing ultra-precision machine tool
System structure is complicated, parts are many, and some problems of precision stability difference high to matching requirements.
The technical scheme is that and be achieved in that: a kind of high accuracy dynamic and static pressure axis system, including main shaft, keep set
Cylinder, oil filler point, front end bearing shell, rear end bearing shell, described main shaft fixes with front end bearing shell, and main shaft and rear end bearing shell are by adjusting pad
Control all to offer cannelure on gap of main reinforcement, holding sleeve outside described main shaft and rear end bearing shell, make on holding sleeve
Oil filler point forms peripheral interconnection and makes oil pocket oil filler point form peripheral interconnection, sleeve oil filler point and rear end bearing shell cavity oil filler point in
Decussation formula is connected so that the oily retaining ring of static pressure oil circuit oil-in is around convection current, and the oil pump that cancels each other out in limits rotates very much
The oil circuit pulsation produced, is the most also avoided that holding sleeve single oilhole blocking causes main shaft to seize.
As preferably, described front end bearing shell and rear end bearing shell are tin bronze alloys bearing shell.
Further, described main shaft is four tapering main shafts, and the both sides closing on the alignment of shafts are provided with radial position play precision
Keep the conical surface, keep the side of the conical surface to be provided with precision and keep the conical surface.The two ends of the alignment of shafts of this structure are provided with radial position and alter
Dynamic precision keeps the conical surface and precision to keep the conical surface, it is simple to bearing shell and the cooperation of sleeve front and back.
Compared with prior art, advantages of the present invention is as follows: amount of parts is few, simple in construction, can realize returning of superelevation
Turn precision, there is the advantage that assembling is simple, precision stability is good.
Accompanying drawing explanation
Fig. 1 is the structural representation after the present invention assembles；
Fig. 2 is the structural representation of main shaft of the present invention；
Fig. 3 is the structural representation of bearing shell of the present invention.
Detailed description of the invention
The detailed description of the invention of the present invention is as follows:
Embodiment 1
As it is shown in figure 1, a kind of high accuracy dynamic and static pressure axis system, including main shaft 1, keep sleeve 2, oil filler point 3, front end axle
Watts 4, rear end bearing shell 5, described main shaft fixes with front end bearing shell, and main shaft and rear end bearing shell control gap of main reinforcement by adjusting pad 6,
Cannelure 7 is all offered, outside making the oil filler point 8 on holding sleeve be formed on holding sleeve outside described main shaft and rear end bearing shell
Enclosing interconnection and make oil pocket oil filler point 9 form peripheral interconnection, sleeve oil filler point and rear end bearing shell cavity oil filler point are decussation formula
Be connected so that the oily retaining ring of static pressure oil circuit oil-in cancel each other out in convection current, very limits oil pump rotate produce oil circuit
Pulsation, is the most also avoided that holding sleeve single oilhole blocking causes main shaft to seize.Described main shaft is four tapering main shafts, closes on master
The both sides at axle center 10 are provided with radial position play precision and keep the conical surface 11, keep the side of the conical surface to be provided with precision and keep the conical surface
12.The two ends of the alignment of shafts of this structure are provided with radial position play precision and keep the conical surface and precision to keep the conical surface, it is simple to front
Rear bearing shell and the cooperation of sleeve.
Above-mentioned high accuracy dynamic and static pressure axis system amount of parts is few, simple in construction, can realize the rotating accuracy of superelevation, tool
There is the advantage that assembling is simple, precision stability is good.
Finally it is pointed out that above example is only the more representational example of the present invention.Obviously, the technology of the present invention
Scheme is not limited to above-described embodiment, it is also possible to have many deformation.Those of ordinary skill in the art can be from disclosed by the invention
All deformation that content directly derives or associates, are all considered as protection scope of the present invention.
