A kind of body of ball high-speed main spindle
Technical field
The utility model relates to a kind of machining equipment, specifically a kind ofly is used for the body that mechanical processing machine ball high-speed electric main shaft is used.
Background technology
In the prior art; the body that ball electricity main shaft is used is mainly used in parts such as fixed installation bearing, bearing block, stator; but shell as main shaft; but often can't protect the operate as normal of each parts; more for high speed ball main shaft; temperature when not providing the work of circulating cooling system reduction main shaft to improve accuracy, increases the service life simultaneously.
Summary of the invention
The utility model relates to a kind of body of ball high-speed main spindle, and parts such as it not only can rigid bearing, bearing block, stator also can be protected each parts operate as normal; because of it is provided with circulating cooling system, also be applicable to high speed ball main shaft, the accuracy height; long service life is convenient to promote and use.
The utility model technical solution is the seal groove (1) on existing body wall, sealing gland hole (2) in circulation cooling bath (11) body wall, the body middle part is provided with stator fixing threaded hole (8), the body base end wall is provided with on the basis of axial bolt hole (9), the utility model is divided into epicoele endoporus (4) and cavity of resorption endoporus (6) particularly in internal body, on, also be provided with a step through-hole (5) between the cavity of resorption endoporus, be provided with the lower bearing lubricating oil air admission hole (10) that communicates with body surface in the body wall, the place of giving vent to anger of lower bearing lubricating oil air admission hole (10) is arranged on the top of cavity of resorption endoporus (6), a side relative with lower bearing lubricating oil air admission hole (10) is provided with upper bearing (metal) air admission hole (7) in the body wall, and a side relative with sealing gland hole (2) is provided with circulation cooling hole (3) in the body wall.
Advantage of the present utility model is:
1, utilize body that bearing directly is installed, easy installation and removal can guarantee assembly precision again;
2, circulating cooling system design, body radiating efficiency height;
3, advantages such as body good rigidly, precision height, long service life; Can be widely used as the body in the various ball high-speed electric main shafts.
