Abstract
The utility model discloses a radial blowing device of a high-speed motorized spindle, which comprises a casing (1), a dust cover (2), a sealing cover (3), a front cover (5) and a spindle head (6). The dust cover (2) is provided with two intersecting holes, an outer circular groove (7) and an inner circular groove (8). The outer circular groove (7) is communicated with the inner circular groove (8) through two air inlets arranged between the outer circular groove (7) and the inner circular groove (8), and the inner circular groove (8) is communicated with the sealing cover (3) through six air outlets arranged between the inner circular groove (8) and the sealing cover (3). The dust cover (2) and a radial end face of an inner circle (4) of the dust cover are in an interference fit, and the axial end face of the inner circle (4) of the dust cover is contacted with the sealing cover (3). A blowing channel is formed by gaps between the inner circle (4) of the dust cover and the dust cover (2) and between the inner circle (4) of the dust cover and the sealing cover (3). By means of the structure, gas sources are distributed evenly in the circumference direction, cutting fluid and metal powders of working pieces are not easy to enter the inside of the high-speed motorized spindle, and service life of a precision bearing is prolonged.
Description
Technical field: the utility model relates to a kind of blowning installation, especially relates to a kind of 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 enter 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, generally adopt additional gas source side formula, only outwards blow, to reach the purpose of removing cutting fluid and metal break flour through the insufflation channel structure.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 purpose of this utility model is to overcome the deficiency that exists in the above-mentioned technology, and a kind of radially shunting blowning installation that can improve the air blowing effect is provided.
The utility model purpose is achieved in that radially blowning installation of a kind of high-speed electric main shaft, comprise casing, dust cover, sealing cover, protecgulum, spindle nose is formed, 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, 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, in communicate by six air outlets between all circular grooves and the sealing cover, dust cover and dust cover inner ring radial end face interference fit, and axial end all contacts with sealing cover, dust cover inner ring and dust cover, the gap of sealing cover forms insufflation channel.
The structure that the utility model adopts, source of the gas is evenly distributed in a circumferential direction, and the metal break flour of cutting fluid and workpiece is difficult for entering high-speed electric main shaft inside, thereby has prolonged the working life of precision bearing.
Description of drawings
For the easier quilt of content of the present utility model is clearly understood, below the concrete enforcement and in conjunction with the accompanying drawings of basis, the utility model is described in further detail:
Fig. 1 is a structural representation of the present utility model
Fig. 2 is the sectional view of A-A among Fig. 1
1. casing 2. dust covers 3. sealing covers 4. dust cover inner rings 5. protecgulums
6. all circular groove 9. suction ports in the spindle nose 7. peripheral annular grooves 8.
Embodiment
A kind of high-speed electric main shaft is blowning installation radially, comprise casing 1, dust cover 2, sealing cover 3, protecgulum 5, spindle nose 6 is formed, 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, be set with dust cover inner ring 4 between dust cover 2 and the sealing cover 3, 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, in communicate by six air outlets between all circular grooves 8 and the sealing cover 3, dust cover 2 and dust cover inner ring 4 radial end face interference fit, and axial end all contacts with sealing cover 3, dust cover inner ring 4 and dust cover 2, the gap of sealing cover 3 forms insufflation channel.9 places connect pressurized gas at suction port, and pressurized gas enters 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 two suction ports again and enter interior all circular grooves 8, is divided into six air outlets again and evenly blows to spindle nose.When electric main shaft ran up, pressurized gas arrived the main shaft leading portion by the insufflation channel of process shown in the arrow, thereby the metal break flour of the cutting fluid of stopping and workpiece enters high-speed electric main shaft inside, can prolong the working life of precision bearing.
The utility model is not made detail to the diameter in insufflation channel hole and is described; as long as pressurized gas arrives front-end of spindle by the passage of certain approach; although big smallest number and approach to the insufflation channel hole are done certain variation, must be considered as having fallen into protection domain of the present utility model.
