Abstract
The utility model discloses an axial air blowing device of a high speed electric spindle, which comprises a machine casing (1), a front cover (2), a front cover inner ring (3), a seal cover (4) and a spindle nose (5). The front cover (2) is provided with two intersection holes, the peripheral face of the front cover inner ring (3) is provided with a left annular groove (6) and a right annular groove (7) which are communicated through two air inlets. The left annular groove (6) and the seal cover are communicated through six air outlets, the front cover (2) is in interference fit with the axial end face of the front cover inner ring (3), and a gap of the front cover (2), the front cover inner ring (3) and the seal cover (4) forms an air blowing channel. The axial air blowing device of the high speed electric spindle adopts a structure that air sources are evenly distributed in the circumferential direction. Cutting liquid and metal dust of workpieces enter the high speed electric spindle uneasily, 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 axial blowning installation that is used for high-speed electric main shaft.
Background technology: 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 needs field of rotation, High-speed machining at a high speed.In process, cutting fluid and metal break flour often get into the inside of high-speed electric main shaft, thereby have influence on the service 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 service life of high-speed electric main shaft.
Summary of the invention:
The purpose of the utility model is to overcome the weak point that exists in the above-mentioned technology, and a kind of axial blowning installation that can improve the high-speed electric main shaft of air blowing effect is provided.
The utility model purpose is achieved in that a kind of axial blowning installation of high-speed electric main shaft, comprises that casing, protecgulum, protecgulum inner ring, seal cover, spindle nose form, and seal cover is sleeved on the spindle nose; The protecgulum inner ring is sleeved on the seal cover; Protecgulum is sleeved on the seal cover and is fastening in casing, and it is characterized in that: protecgulum is provided with two crossing holes, and protecgulum inner ring periphery is provided with left cannelure and right cannelure; Communicate by two air inlets between a left side cannelure and the right cannelure; Communicate protecgulum and protecgulum inner ring axial end interference fit, the gap formation insufflation channel of protecgulum and protecgulum inner ring, seal cover between a left side cannelure and the seal cover by six gas outlets.
The structure that the utility model 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 service life of precision bearing.
Description of drawings
For the content that makes the utility model is more clearly understood, below basis practical implementation and combine accompanying drawing, the utility model is done further detailed explanation:

Fig. 2 be among Fig. 1 A to figure
1. casing 2. protecgulums 3. protecgulum inner rings 4. seal covers 5. spindle noses
6. left cannelure 7. right cannelure 8. air inlets
The specific embodiment
A kind of axial blowning installation of high-speed electric main shaft comprises casing 1, protecgulum 2, protecgulum inner ring 3, seal cover 4,5 compositions of spindle nose, and seal cover 4 is sleeved on the spindle nose 5; Protecgulum inner ring 3 is sleeved on the seal cover 4; Protecgulum 2 is sleeved on the seal cover 4 and is fastening in casing 1, and protecgulum 2 is provided with two crossing holes, and protecgulum inner ring 3 peripheries are provided with left cannelure 6 and right cannelure 7; Communicate by two air inlets between a left side cannelure 6 and the right cannelure 7; Communicate protecgulum 2 and protecgulum inner ring 3 axial end interference fit, the gap formation insufflation channel of protecgulum 2 and protecgulum inner ring 3, seal cover 4 between a left side cannelure 6 and the seal cover 4 by six gas outlets.8 places connect Compressed Gas at air inlet, and Compressed Gas gets into right cannelure 7 by an air inlet when the axial end of process protecgulum 2 and protecgulum inner ring 3, be divided into two air inlets and get into left cannelure 6, is divided into six gas outlets again and evenly blows to spindle nose.When electric main shaft ran up, Compressed 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 service life of precision bearing.
The utility model is not made detail to the diameter in insufflation channel hole and is described; As long as Compressed 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 the protection domain of the utility model.
