Description
Technical field
This patent is related to a kind of fixture for lathe process, more particularly to a kind of for processing slim cannula-like on lathe
Clamping device inside and outside eight claws of part.
Background technology
In field of machining, the slim shell-like of lathe process and tubular member, these slim cannula-like parts are often used
It is clamped through conventional chuck in processing.Because of the support of incorporeity raw material between claw at two pairs on same straight line,
Part is influenceed after clamping and is deformed by clamping force, and this often causes part circularity and cylindricity after processing to miss
The excessive phenomenon of difference, or even part can also depart from claw and fly out and hurts sb.'s feelings in process.Its reason essentially consists in part clamping
The tube wall at position is relatively thin, it is difficult to bear larger clamping force and cutting force, deforms this generates clamping, and holds and does not fly then tightly
The processing problem for going out.
Traditional processing method is to carry out turning from the thicker hollow raw material of solid or wall thickness, after the completion of turning again
Slim cannula-like part is cut down from thicker raw material, but this processing method extremely wastes raw material, processing compared with
It is this during heavy parts to waste particularly evident, also this method is also easily deformed because allowance is excessive.Also kind side
Rule is with less clamping force to carry out Clamp blocks and be processed, when being processed using this kind of method, for the sake of security, must not
The not depth of cut of selection of small, the amount of feeding and relatively low rotating speed, therefore the yield rate of these methods and all production efficiency is relatively low
Under.
