Description
Technical field
The utility model relates to field of mechanical technique, and in particular to a kind of plus guiding safety chuck.
Background technique
What common standard security collet leaned in the market is the frictional force that generates between spring and steel ball to guarantee that disk is being transported
It is not opened when row, but this frictional force is limited.Due to various reasons, disk can be in half-dozen in the process of running
The state opened, the self-locking inclined-plane dry friction with safety chuck is to generate a large amount of metal fillings.Common safety chuck is because have
Frictional force between spring and steel ball exists, and opens the power that disk will be very big (if operator when the diameter of material is bigger
Hand to extend have an effect it is relatively difficult be just more difficult open disk).The square chuck of standard should be driven and position again, every turn of collet one
The dragging of a 90 degree of air-expanding shafts and collet just has one at mouth cooperation alters and hits, and gap can easily become larger in use.Gap is bigger
Material at runtime stationarity it is poorer alter hit it is just also big.
Therefore, present market is using directly pushing away safety chuck because the problem of cooperation precision it is most of be all it is round, by riding
Key of joint transmits torque, the general trisection of junction of the edges of two sheets of paper pin.Junction of the edges of two sheets of paper pin is smaller and is trisection, this results in being put into air-expanding shaft
When on collet support mouth will pair comparison fiducial axis can just be put into position, such relatively time-consuming of operation.Axis is bad, and to be put into position time-consuming
Laborious inefficiency, simultaneously as misalignment be easy to cause destruction cooperation precision of colliding with.
