Abstract
The invention relates to a dust cover of a ball high-speed main shaft. An inner hole of the dust cover is a step type hole. A decompression groove is formed in the bottom of a first step hole. More than one decompression hole which is communicated with the outer end face of the dust cover is formed in the bottom of the decompression groove. The dust cover of the ball high-speed main shaft can enable condensate water brought by dry air which enters into a main shaft, or cutting fluid which enters into the end portion of the main shaft to flow out through the decompression groove and the decompression hole, when the condensate water or the cutting fluid passes by the decompression groove and the decompression hole, and prevents the condensate water or the cutting fluid from entering into positions of a main shaft bearing and a motor stator and damaging the main shaft bearing and the motor stator.
Description
Technical field
The present invention relates to a kind of machining equipment, specifically a kind of dust cover for using on speed electric rolling-ball main shaft.
Background technology
In the prior art, pearl high-speed electric main shaft front end adopts air seal, but the gas after compression is because drying is not thorough, condensed water is arranged in gas all the time, main shaft can be brought part into main shaft inside in when operation, thereby damages bearing and spindle motor, and condensed water reduces the main shaft life-span.
Summary of the invention
The object of the invention is to for overcoming the defective of prior art, and a kind of dust cover of ball high-speed spindle is provided, it is simple in structure, and sealing property is high, and long service life is convenient to promote and use.
For achieving the above object, the present invention is by the following technical solutions: a kind of dust cover of ball high-speed spindle, described dust cover endoporus is stepped bore, is provided with gas pressure relief slot in the bottom of the first shoulder hole, is provided with more than one the relief hole that is communicated with the dust cover outer face in the bottom of gas pressure relief slot.
Described relief hole is two, and is symmetrical with the axle center of dust cover endoporus.
Described gas pressure relief slot is the spill annular groove that is located at the inwall bottom of the first shoulder hole.
The table top of described the second shoulder hole is provided with accommodating annular groove, establishes airtight seal ring in accommodating annular groove, is provided with the intake channel that is communicated with between the madial wall of accommodating annular groove and dust cover inner face or sidewall.
Be respectively equipped with inside and outside annular groove on described airtight seal ring internal and external circumference, be provided with one between the bottom of inside and outside annular groove with coconnected passage.
Described passage is 8, is evenly distributed in the ring body of airtight seal ring.
Described airtight seal ring and accommodating annular groove are interference fit.
1), when the main shaft high-speed cruising the present invention's beneficial effect compared with prior art is:, dust cap can produce centrifugal force, make the dust cap position can produce pressure differential, thereby the cutting fluid that will flow through condensed water in the gas of airtight seal ring or spindle nose is drawn into main shaft inside; And after being provided with gas pressure relief slot and relief hole on the endoporus of dust cover, when condensed water or cutting fluid flow through gas pressure relief slot, can flow out from relief hole, prevent from continuing to enter main shaft bearing and motor position, thereby prevent from damaging bearing and burn out stator, extending like this Main Shaft Service Life; 2), hermetic seal is equipped with inside and outside annular groove and passage, is evenly distributed on outlet when gas blows out, dirt, bits and the cutting fluid that produces in the time of effectively preventing processing work enters main shaft inside, strengthens main shaft seal.3), simple in structure, convenient processing, assembling can be widely used as the dedusting structure in various high-speed electric main shafts.
