Abstract
The utility model provides a novel static and dynamic pressure main shaft, including a main shaft, be equipped with oil groove and oil pocket in the main shaft, be equipped with the main shaft rotor in the oil pocket, be equipped with a plurality of through -hole that volatilizees in the oil pocket, the top of main shaft is equipped with rotary fixture, the last li of the being equipped with level sensor of rotary fixture, be equipped with displacement sensor in the oil pocket, be equipped with the pressure spring between main shaft rotor and the oil pocket, be equipped with the thrust oil pocket between main shaft rotor and the main shaft, it fills up to be equipped with the adjustment in the thrust oil pocket, it is equipped with filtration membrane to volatilize between through -hole and the oil pocket, be equipped with the adapter cavity between oil pocket and oil groove, can balanced oil groove and the oil pocket between pressure, it is too big to avoid the pressure error between oil groove and the oil pocket, the safe and stable operation of main shaft has been influenced, can volatilize is equipped with filtration membrane between through -hole and the oil pocket, the impurity that can effectively avoid pressure oil gets into the main shaft, the result of use of main shaft has been guaranteed.
Description
Technical field
The utility model relates to main shaft, is specifically related to a kind of Novel movable hydrostatic spindle.
Background technique
Lathe can use transmission device, these transmission device band dynamic cutter heads run, cutter head is allowed to carry out process component under running up, meet the process requirements of different component, transmission device on general lathe is transmission shaft, transmission shaft when in use, when being connected with lathe, easy appearance connects unstable phenomenon, cause main shaft to connect to occur rocking, have impact on the actual transmission effect of main shaft, especially some main shafts need hydraulic oil to carry out promotion operation, hydraulic oil needs to be thought to flow in oil groove by oil pocket in the process run, pressure often between oil groove from oil pocket is different, cause hydraulic oil local strength in course of conveying excessive, have impact on the using effect of main shaft.
Summary of the invention
It is good that the purpose of this utility model is to provide a kind of oil pressure cntrol, the simple a kind of Novel movable hydrostatic spindle of structure.
The technical solution of the utility model is: a kind of Novel movable hydrostatic spindle, comprise main shaft, oil groove and oil pocket is provided with in described main shaft, spindle rotor is provided with in oil pocket, several volatilization through holes are provided with in oil pocket, the top of main shaft is provided with rolling clamp, rolling clamp is provided with strength sensor, displacement transducer is provided with in oil pocket, the number of displacement transducer is 2-8, stage clip is provided with between spindle rotor and oil pocket, stage clip is butterfly stage clip or torsion spring, thrust oil pocket is provided with between spindle rotor and main shaft, spacer is provided with in thrust oil pocket, spacer is flat structure, filter membrane is provided with between volatilization through hole and oil pocket, filter membrane eye diameter is less than the diameter of volatilization through hole.
Described strength sensor is plugged on rolling clamp, and strength sensor is connected with machine tool control system.
Described displacement transducer is inductive displacement transducer, and displacement transducer is connected with machine tool control system.
The number of described oil pocket is several and is provided with adapter cavity between oil pocket and oil groove, and adapter cavity is circular ring.
The utility model has the advantages that: between oil pocket and oil groove, be provided with adapter cavity, can pressure between balanced oil groove and oil pocket, avoid the pressure error between oil groove and oil pocket too large, the safety and steady that have impact on main shaft runs, can volatilize between through hole and oil pocket and be provided with filter membrane, the impurity of pressure oil effectively can be avoided to enter main shaft, ensure that the using effect of main shaft.
