Description
Technical field
The present invention relates to a kind of fixture for lathe process, process slim cannula-like particularly to a kind of on lathe
Clamping device inside and outside eight claws of part.
Background technology
In field of machining, the often slim shell-like of lathe process to be used and tubular member, these slim cannula-like parts
It is clamped through conventional chuck in processing.Because of the support of incorporeity raw material between claw on same straight line at two pairs,
Part is affected by clamping force after clamping and is deformed, and this part circularity after often causing to process and cylindricity are by mistake
The excessive phenomenon of difference, or even part also can depart from claw and flies out and hurts sb.'s feelings in process.Its reason essentially consists in part clamping
The tube wall at position relatively thin it is difficult to bear larger clamping force and cutting force, this generates clamping deform, hold and tightly then do not fly
The processing difficult problem 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, in processing relatively
During heavy parts, this waste is particularly evident, moreover this method is also easily deformed because allowance is excessive.Also has kind side
Rule is to carry out Clamp blocks with less clamping force and be processed, when being processed using this kind of method, for the sake of security, must not
The depth of cut of selection of small, the amount of feeding and relatively low rotating speed, the therefore yield rate of these methods and all production efficiency be not relatively low
Under.
