Abstract
The invention discloses an axial blowing device of a high-speed electric spindle. The axial blowing device comprises a casing (1), a front cover (2), a front cover inner ring (3), a sealing cover (4) and a shaft head (5), wherein two crossing holes are formed in the front cover (2); a left annular groove (6) and a right annular groove (7) are arranged on the circumference surface of the front cover inner ring (3) and are communicated with each other through two air inlets; the left annular groove (6) is communicated with the sealing cover (4) by six air outlets; the front cover (2) is in interference fit with the axial end surface of the front cover inner ring (3); and a blowing channel is formed in a gap between the front cover (2) and the front cover inner ring (3) as well as the sealing cover (4). With the adoption of the structure, air sources are uniformly distributed in the circumference direction, and cutting liquid and metal powder crumbs of workpieces difficultly enter the inside of the high-speed electric spindle, so that the service life of an accurate bearing is prolonged.
Description
Technical field: the present invention relates to a kind of blowning installation, especially relate to a kind of axial 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 axial blowning installation that can improve the high-speed electric main shaft of air blowing effect is provided.
The present invention seeks to realize like this: the axial blowning installation of high-speed electric main shaft, comprise that casing, protecgulum, protecgulum inner ring, sealing cover, spindle nose form, sealing cover is sleeved on the spindle nose; The protecgulum inner ring is sleeved on the sealing cover; Protecgulum is sleeved on the sealing cover and is fastening in casing, and it is characterized in that: protecgulum is provided with two crossing holes, and protecgulum inner ring circumferential surface is provided with left circular groove and right circular groove; Communicate by two suction ports between a left side circular groove and the right circular groove; Communicate protecgulum and protecgulum inner ring axial end interference fit, the gap formation insufflation channel of protecgulum and protecgulum inner ring, sealing cover between a left side circular groove and the sealing cover by six air outlets.
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.

Embodiment
The axial blowning installation of high-speed electric main shaft comprises casing 1, protecgulum 2, protecgulum inner ring 3, sealing cover 4,5 compositions of spindle nose, and sealing cover 4 is sleeved on the spindle nose 5; Protecgulum inner ring 3 is sleeved on the sealing cover 4; Protecgulum 2 is sleeved on the sealing cover 4 and is fastening in casing 1, and protecgulum 2 is provided with two crossing holes, and protecgulum inner ring 3 circumferential surfacies are provided with left circular groove 6 and right circular groove 7; Communicate by two suction ports between a left side circular groove 6 and the right circular groove 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, sealing cover 4 between a left side circular groove 6 and the sealing cover 4 by six air outlets.8 places connect pressurized gas at suction port, and pressurized gas gets into right circular groove 7 by a suction port when the axial end of process protecgulum 2 and protecgulum inner ring 3, be divided into two suction ports and get into left circular groove 6, 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.
