Description
Technical field
The present invention relates to electro spindle more particularly to a kind of ball electric spindles.
Background technology
Electro spindle when in use, the step of being usually directed to loading cutter or dismantle cutter, in the above process, is typically being drawn
Bar, push rod mating reaction under realize that the handling of cutter are completed in push-and-pull to handle of a knife, cooperation.But, it is generally the case that push rod and
Be between pull rod be directly connected to or only using push rod come pushing drawing rod, cause to load after cutter or even run in electro spindle
Cheng Zhong can generate friction between pull rod and push rod, not only influence equipment normal operation, can also cause component wear, and then produce
Raw many hazards.
In addition, currently, the working end of electro spindle generally uses two kinds of safeguard structures, one is the working ends in electro spindle to add
Dress protective cover influences the service life of electro spindle the disadvantage is that not can effectively prevent water enters electro spindle；Another kind is using single
One sealing ring, the disadvantage is that being easy to fever damage in electro spindle high-speed cruising, it is difficult to prevent water from entering in electro spindle.It can
See, both safeguard structures not can effectively prevent water, dirt etc. and enter in electro spindle, and electro spindle is greatly reduced uses the longevity
Life.Secondly because electro spindle, under the action of high speed rotation, each parts of electro spindle will produce different degrees of fever.Fever
Relative position between electro spindle and lathe other parts and size afterwards all will with it is different therefore produced before fever
