Description
Technical field
The utility model belongs to machine tool chief axis sealed member field, is specifically related to a kind of electric main shaft of digital control machine tool High Rotation Speed black box.
Background technique
Electrical spindle for machine tool is high speed, high precision machine tool functional part, under electro spindle is in water, oil and processing scrap environment, foreign matter enters electro spindle and causes main shaft to damage, current black box comprises fixing outer shroud and rotates inner ring, be provided with Sealing between fixing outer shroud and rotation inner ring, due to electro spindle High Rotation Speed, general contact seals been has has been worn and torn and cannot have been used, cannot main shaft be sealed up, therefore need a kind of Sealing that can seal main shaft at electro spindle High Rotation Speed.
Model utility content
The purpose of this utility model is to provide a kind of electric main shaft of digital control machine tool High Rotation Speed black box, and its convenient installation, can seal it when main shaft High Rotation Speed, prevent foreign object from entering main shaft.
The utility model relates to a kind of electric main shaft of digital control machine tool High Rotation Speed black box, comprise fixing outer shroud and rotate inner ring, seal ring is provided with between fixing outer shroud and rotation inner ring, seal ring is made up of fixing seal ring and rotating seal ring, fixing seal ring is fixedly connected on fixing outer shroud by fixed block one, rotating seal ring is fixedly connected on by fixed block two and rotates in inner ring, for profile of tooth coordinates between fixing seal ring and rotating seal ring, the gap of a 0.03mm to 0.05mm is had between fixing seal ring and rotating seal ring, and it is 30 ° of hypotenuses while be straight flange that the profile of tooth of fixing seal ring and rotating seal ring is.
Fixing seal ring is made up of fixing seal ring outer member and fixing seal ring internals, and fixing seal ring internals have 1 to 6.
Rotating seal ring is made up of rotating seal ring outer member and rotating seal ring internals, and rotating seal ring internals have 1 to 6.
Compared with prior art, the utility model has the advantage of:
Convenient installation, easily manufactured, can seal it when main shaft High Rotation Speed, prevent foreign object from entering main shaft.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
In figure: 1, fixing outer shroud, 2, fixing seal ring, 3, rotating seal ring, 4, rotate inner ring, 5, fixed block one, 6, gap, 7, fixed block two, 8, fixing seal ring outer member, 9, rotating seal ring internals, 10, rotating seal ring outer member, 11, fixing seal ring internals.
Embodiment
Contrast accompanying drawing below, embodiment of the present utility model is described in further detail.
The utility model relates to a kind of electric main shaft of digital control machine tool High Rotation Speed black box as shown in Figure 1, comprise fixing outer shroud 1 and rotate inner ring 4, seal ring is provided with between fixing outer shroud 1 and rotation inner ring 4, seal ring is made up of fixing seal ring 2 and rotating seal ring 3, fixing seal ring 2 is fixedly connected on fixing outer shroud 1 by fixed block 27, rotating seal ring 3 is fixedly connected on by fixed block 1 and rotates in inner ring 4, for profile of tooth coordinates between fixing seal ring 2 and rotating seal ring 3, the gap 6 of a 0.03mm to 0.05mm is had between fixing seal ring 2 and rotating seal ring 4, it is 30 ° of hypotenuses while be straight flange that the profile of tooth of fixing seal ring 2 and rotating seal ring 3 is.
Fixing seal ring 2 is made up of fixing seal ring outer member 8 and fixing seal ring internals 11, and fixing seal ring internals 11 have 3, and fixing seal ring 2 uses combined type to be convenient to manufacture.
Rotating seal ring 3 is made up of rotating seal ring outer member 10 and rotating seal ring internals 9, and rotating seal ring internals 9 have 3, and rotating seal ring 3 uses combined type to be convenient to manufacture.
During assembling, rotation inner ring 4 of the present utility model and main shaft are coordinated rotation inner ring 4 is moved together with main shaft, and fixing outer shroud 1 is fixed on machine tool body, fixing seal ring 2 and rotating seal ring 3 all have outer member and internals to form, easily manufactured; Produce air-flow during rotation to be rejected outside main shaft thing by gap 6, prevent foreign object from entering main shaft.The utility model can make standard piece, conveniently installs and uses.
The utility model is convenient in sum installs, easily manufactured, can seal, prevent foreign object from entering main shaft when main shaft High Rotation Speed to it.
The above is exemplarily described the utility model; obvious the utility model specific implementation is not subject to the restrictions described above; no matter be do any change in its shape or structure; as long as have employed the improvement of the various unsubstantialities that method of the present utility model is conceived and technological scheme is carried out; or design of the present utility model and technological scheme directly applied to other occasion, all within protection domain of the present utility model without to improve.
