Abstract
The invention discloses a radial blowing device for a high-speed electric spindle. The radial blowing device comprises a machine shell (1), a dustproof cover (2), a sealing cover (3), a front cover (5) and a spindle nose (6). Two intersecting holes are formed on the dustproof cover (2); an outer circumference annular groove (7) and an inner circumference annular groove (8) are arranged on the dustproof cover (2); the outer circumference annular groove (7) is communicated with the inner circumference annular groove (8) through two air inlets; the inner circumference annular groove (8) is communicated with the sealing cover (3) through six air outlets; the dustproof cover (2) and a radial end face of a dustproof cover inner ring (4) are in interference fit; an axial end face of the dustproof cover inner ring (4) is in contact with the sealing cover (3); and an air blowing channel is formed between the dustproof cover inner ring (4) and a gap between the dustproof cover (2) and the sealing cover (3). With the adoption of the structure adopted by the invention, gas sources are uniformly distributed in the circumference direction; cutting fluid and metal powder of a working piece can not easily enter the inside the high-speed electric spindle; and the service life of a precise bearing is prolonged.
Description
Technical field: the present invention relates to a kind of blowning installation, especially relate to the radially blowning installation that is used for high-speed electric main shaft.
Background technique: at present; High-speed electric main shaft is the very high electromechanical integrated product of a kind of technology content; Through development and perfect constantly, its application spreads all over machine industry, bearing industry, electronics processing industry, Mould Machining industry and all need the field of high speed rotating, High-speed machining.In course of working, cutting fluid and metal break flour often get into the inside of high-speed electric main shaft, thereby have influence on the working life of the inner precision bearing of high-speed electric main shaft.At present, the general source of the gas mode that adds that adopts is only outwards blown through the insufflation channel structure, to reach the purpose of removing cutting fluid and metal break flour.But this structure is even inadequately owing to source of the gas distributes in a circumferential direction, and the effect that causes blowing is undesirable, thereby has influenced the working life of high-speed electric main shaft.
Summary of the invention:
The objective of the invention is to overcome the deficiency that exists in the above-mentioned technology, a kind of radially shunting blowning installation that can improve the air blowing effect is provided.
The present invention seeks to realize like this: high-speed electric main shaft is blowning installation radially, comprises that casing, dust cover, sealing cover, protecgulum, spindle nose form, and sealing cover is sleeved on the spindle nose; Protecgulum is sleeved on the sealing cover; Dust cover is sleeved on the sealing cover and is fastening in casing, and it is characterized in that: be set with the dust cover inner ring between dust cover and the sealing cover, dust cover is provided with two crossing holes; Dust cover is provided with peripheral annular groove and interior all circular grooves; Communicate by two suction ports between peripheral annular groove and the interior all circular grooves, communicate dust cover and dust cover inner ring radial end face interference fit by six air outlets between interior all circular grooves and the sealing cover; And axial end all contacts with sealing cover, and the gap of dust cover inner ring and dust cover, sealing cover forms insufflation channel.
The structure that the present invention adopts, source of the gas is evenly distributed in a circumferential direction, and it is inner that the metal break flour of cutting fluid and workpiece is difficult for getting into high-speed electric main shaft, thereby prolonged the working life of precision bearing.
Description of drawings
For content of the present invention is more clearly understood, below basis practical implementation and combine accompanying drawing, the present invention is done further detailed explanation:
Fig. 1 is a structural representation of the present invention
Fig. 2 is the sectional view of A-A among Fig. 1
1. all circular groove 9. suction ports in the casing 2. dust covers 3. sealing covers 4. dust cover inner rings 5. protecgulums 6. spindle noses 7. peripheral annular grooves 8.
Embodiment
High-speed electric main shaft is blowning installation radially, comprises casing 1, dust cover 2, sealing cover 3, protecgulum 5,6 compositions of spindle nose, and sealing cover 3 is sleeved on the spindle nose 6; Protecgulum 5 is sleeved on the sealing cover 3; Dust cover 2 is sleeved on the sealing cover 3 and is fastening in casing 1, is set with dust cover inner ring 4 between dust cover 2 and the sealing cover 3, and dust cover 2 is provided with two crossing holes; Dust cover 2 is provided with peripheral annular groove 7 and interior all circular grooves 8; Communicate by two suction ports between peripheral annular groove 7 and the interior all circular grooves 8, communicate dust cover 2 and dust cover inner ring 4 radial end face interference fit by six air outlets between interior all circular grooves 8 and the sealing cover 3; And axial end all contacts with sealing cover 3, and dust cover inner ring 4 forms insufflation channel with the gap of dust cover 2, sealing cover 3.9 places connect pressurized gas at suction port, and pressurized gas gets into peripheral annular groove 7 by a suction port when the radial end face of process dust cover 2 and dust cover inner ring 4, be divided into all circular grooves 8 in the entering of two suction ports again, is divided into six air outlets again and evenly blows to spindle nose.When electric main shaft ran up, pressurized gas is by arriving the main shaft leading portion through insufflation channel shown in the arrow, and was inner thereby the metal break flour of the cutting fluid of stopping and workpiece gets into high-speed electric main shaft, can prolong the working life of precision bearing.
The present invention does not make detail to the diameter in insufflation channel hole and describes; As long as pressurized gas arrives front-end of spindle through the passage of certain approach; Although big smallest number and approach to the insufflation channel hole are done certain variation, must be regarded as having fallen into protection scope of the present invention.
