Description
Technical field
The utility model relates to fixtures, more particularly to a kind of double flute axis milling fixture.
Background technique
In general, it is common for opening up keyway on axis, and only need to fix two end faces of axis, then be existed by milling machine
Designated position mills out keyway.But the processing of the axis of double bond slot is just less easy, it needs to first on axis
Keyway is processed, and is then relocated according to the position of first keyway to axis, then carries out second keyway again
Milling.In the prior art, not on the same line due to two keyways, and the position of two keyways is any, the prior art
Locating clip clamping of workpieces is with regard to very troublesome.Specifically, need in the prior art to first keyway correction bus and centering it is symmetrical in
Then the heart mills out first keyway, and process before second keyway, need the bus for correcting keyway again and find in symmetrical
The heart is fixed workpiece by fixture later, then is processed to second keyway.Therefore, the double flute axis milling folder of the prior art
Tool needs repeatedly to correct when processing second keyway, and corrects the influence that will receive the technical level of operator, and one
Processing efficiency is low for aspect, and another aspect processing quality is not easily controlled.It is also due to above-mentioned reason, in the prior art less meeting
The axis of double bond slot is used, and frequently with the axis of single key slot.However, the stability of the axis of double bond slot is higher than single key slot, application
Prospect is more preferable.Similarly, for the axis for needing to open up keyway and oil groove, there is also the same problems, the problem also it is generally existing
In the processing technology of the axis of double flute.
