Abstract
The utility model discloses a self gas blowing device of a high-speed electric spindle with left-hand thread, which comprises a main shaft (3), a sealing cover (1) which is engagingly mounted with the main shaft (3), and a front cover (4) which is sleeved on the sealing cover (1), wherein the inner diameter of the sealing cover (1) is provided screws whose spiral directions are opposite to an outer diameter. A dust cap (2) is arranged between the front cover (4) and the sealing cover (1), the dust cap (2) is sleeved on the outer screw of the sealing cover (1), and a radial gap channel (5) is arranged between the sealing cover and the dust cover. With the structure, the self gas blowing device can avoid cutting fluid and metal power chip from entering a high-speed electric main shaft, thereby prolonging the service span of a precision bearing, in addition, lowering the processing cost of the high-speed electric main shaft since a gas source is not needed to be additionally added.
Description
Technical field
The utility model relates to a kind of electric spindle technology, and the band left-hand thread that especially relates to a kind of high-speed electric main shaft is from blowning installation.
Background technology
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 the course of processing, cutting fluid and metal break flour often enter the inside of high-speed electric main shaft, thereby have influence on the useful life of the inner precision bearing of high-speed electric main shaft.At present, the general employing adds source of the gas, outwards blows through insufflation channel, to reach the purpose of removing cutting fluid and metal break flour.This mode has increased processing cost owing to be provided with the air inlet duct on part; In addition, if it is moist to add source of the gas, the air of trace also can be to bearing generation effect, thereby influences the useful life of bearing.
Summary of the invention
The purpose of this utility model provides a kind of band left-hand thread of the high-speed electric main shaft that does not need to add source of the gas from blowning installation.
The problem of the required solution of the utility model realizes by the following technical solutions: it comprises main shaft, cooperate the seal cover of installing with main shaft and be enclosed within protecgulum on the seal cover, the internal diameter of seal cover is provided with the opposite screw thread of the hand of spiral with external diameter, between protecgulum and seal cover, be provided with dust cap, dust cap is enclosed within on the external screw thread of seal cover, and seal cover and dust cap are provided with the radial clearance passage.
The said structure that the utility model adopts can be stopped cutting fluid and the metal break flour enters high-speed electric main shaft inside, thereby prolongs the useful life of precision bearing; In addition, owing to do not need to add source of the gas, also reduced the processing cost of high-speed electric main shaft.
Description of drawings
Below in conjunction with accompanying drawing the utility model is described further:
Accompanying drawing is depicted as structural representation of the present utility model
Embodiment
By accompanying drawing as can be known, the band left-hand thread of this high-speed electric main shaft comprises main shaft 3, cooperates the seal cover of installing 1 with main shaft 3 and is enclosed within protecgulum 4 on the seal cover 1 that from blowning installation the internal diameter of seal cover 1 is provided with the opposite screw thread of the hand of spiral with external diameter.As being left hand thread on the internal diameter of seal cover 1, then should be right-handed thread on its external diameter; As being right-handed thread on the internal diameter of seal cover 1, then should be left hand thread on its external diameter.Be provided with dust cap 2 between protecgulum 4 and seal cover 1, dust cap 2 is enclosed within on the external screw thread of seal cover 1, and seal cover and dust cap are provided with radial clearance passage 5.When electric main shaft runs up, main shaft runs up with cooperating the seal cover that is installed on it, dust cap is relative with protecgulum static, because the internal diameter of seal cover is provided with the opposite screw thread of the hand of spiral with external diameter, under the effect of draught head, gas in the gap of the outer-diameter threads of seal cover and dust cap, protecgulum can outwards blow from the radial clearance passage of seal cover and dust cap, thereby the metal break flour of the cutting fluid of stopping and workpiece enters the useful life of high-speed electric main shaft internal influence precision bearing.
Claims (1)
1, a kind of band left-hand thread of high-speed electric main shaft is from blowning installation, comprise main shaft, cooperate the seal cover of installing with main shaft and be enclosed within protecgulum on the seal cover, it is characterized in that: the internal diameter of seal cover is provided with the opposite screw thread of the hand of spiral with external diameter, between protecgulum and seal cover, be provided with dust cap, dust cap is enclosed within on the external screw thread of seal cover, and seal cover and dust cap are provided with the radial clearance passage.
