Abstract
Disclosed is a bearing seat sealing device of an air floatation high-speed electric spindle. The device comprises a bearing seat (1), an upper axial damping plug (2), a lower axial damping plug (3), a radial damping plug (4), an upper axial airway (5), lower axial airways (6), an upper radial airway (7), a lower radial airway (8), an annular gas groove (9), an air inlet joint (10) and a sealing ring (11). The device allows high-pressure gas to get into any lower axial airway. The sealing ring plays a role of sealing gas and stabilizing the bearing seat to effectively prevent unstable motion of the high-pressure gas from damaging the sealing ring and related components. The sealing ring is simple in structure, and integrated with the bearing seat without an additional gas sealing device. The damping plugs achieve throttling effects.
Description
Technical field
The utility model relates to a kind of machining equipment, is specifically related to a kind of bearing pedestal seal device of the air floated high speed electric mandrel for machining.
Background technology
The bearing block of air floated high speed electric mandrel is a kind of high accuracy support component, and it is high that it has rotating accuracy, rub little, and the series of advantages such as not raying impact.But the bearing block of traditional air floated high speed electric mandrel is had relatively high expectations to processing technology, processing and assembling difficulty, the bearing block structure of making is single, gas flows too fast in air flue, and the flowing instability that easily occurs gas causes the phenomenon of bearing block locking main shaft, cause device impaired, service life is low, need to frequently change.
Utility model content
In order to overcome the deficiencies in the prior art, the purpose of this utility model is to provide a kind of bearing pedestal seal device of air floated high speed electric mandrel.
For addressing the above problem, the technical scheme that the utility model adopts is as follows:
A kind of bearing pedestal seal device of air floated high speed electric mandrel, comprise: bearing seat (1), upper axial damping plug (2), lower axial damping plug (3), damping plug (4) radially, upper axial air flue (5), lower axial air flue (6), on air flue (7) radially, under air flue (8) radially, annular gas tank (9), inlet suction port (10), sealing ring (11), described axial air flue (5), lower axial air flue (6), on radially air flue (7) and under radially air flue (8) be arranged in successively from top to bottom described bearing seat (1) wall body and be interconnected, described axial damping plug (2) is placed in the upper end of described axial air flue (5), described lower axial damping plug (3) is placed in the lower end of described lower axial air flue (6), on described radially air flue (7) and under radially air flue (8) be placed with respectively radially damping plug (4) by bearing seat inwall end, under described, radially air flue (8) other end is provided with the described sealing ring (11) for sealing gas, described inlet suction port (9) is connected with lower axial air flue (6), the intersection of air flue (8) and lower axial air flue (6) radially under described annular gas tank (9) is positioned at.
Described sealing ring is rubber ring.
Compared to existing technology, the beneficial effects of the utility model are: gases at high pressure can enter any one lower axial air flue by inlet suction port, sealing ring plays the effect of sealing gas, stable axis bearing, the unstable play that effectively prevents gases at high pressure makes self and associated components thereof impaired, and ring structure is simple, one-body molded with bearing block, not needing increases the device that seals gas again, and damping plug can play throttling action.
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Accompanying drawing explanation
Fig. 1 is part sectioned view of the present utility model.
The specific embodiment
Fig. 1 shows preferred embodiment of the present utility model, the utility model comprises: bearing seat 1, upper axial damping plug 2, lower axial damping plug 3, radially damping plug 4, upper axial air flue 5, lower axial air flue 6, on radially air flue 7, under radially air flue 8, annular gas tank 9, inlet suction port 10, sealing ring 11.Working method of the present utility model is as follows: gases at high pressure enter any one lower axial air flue 6 by inlet suction port 10, each lower axial air flue 6 respectively with the upper radially air flue 7 corresponding with it, under radially air flue 8 be connected and communicate with annular gas tank 9, on radially air flue 7 be connected and communicate with upper axial air flue 7 again, gases at high pressure enter annular gas tank 9 from lower axial air flue 6, by annular gas tank 9, enter every other air flue again, reach all air flues and all lead to gases at high pressure, on radially air flue 7 and under radially air flue 8 be respectively equipped with radially damping plug 4, upper axial air flue 5 is provided with axial damping plug 2, lower axial air flue 6 is provided with lower axial damping plug 3, gases at high pressure enter bearing block inside by each damping plug, make bearing block produce the effect of air supporting supports main shaft.In gas flow process, the impulsive force of gases at high pressure is large, more easily makes especially bearing seat impaired in annular gas tank 6, by making air seal in air drain at the peripheral sealing ring 11 that increases of annular gas tank 9, can also make bearing block more solid and reliable, sealing ring 8 can be rubber ring.
Above-mentioned embodiment is only preferred embodiment of the present utility model; can not limit with this scope of the utility model protection, the variation of any unsubstantiality that those skilled in the art does on basis of the present utility model and replacement all belong to the utility model scope required for protection.
