Abstract

The invention discloses a connecting piece for a numerically controlled lathe and heat treatment technology thereof. The connecting piece comprises a body and a heat treatment process, wherein the upper end of the body is designed into a cylindrical structure, namely a first cylindrical structure; the lower end of the body is also designed into the cylindrical structure, namely a second cylindrical structure; the middle of the body is designed into the cylindrical structure, namely a third cylindrical structure; two annular snap spring grooves, namely an upper snap spring groove and a lower snap spring groove, are formed in the middle of the third cylindrical structure; the bottom of the body is also designed into the cylindrical structure, namely a fourth cylindrical structure; a cylindrical groove is formed between the second cylindrical structure and the fourth cylindrical structure. The heat treatment technology of the connecting piece is characterized in that the connecting piece is heated to be austenitized and then is immersed into a proper quenching medium for cooling at a higher speed. The connecting piece disclosed by the invention has the advantages that the tensile strength is high enough, so that the elongation, pull cut, thread slipping and wearing are resisted; the fatigue resistance and impact toughness are higher, so that the fatigue and impact fracture can be resisted; the connecting piece can be better applied to the numerically controlled lathe.

Description

technical field [0001] The invention relates to a mechanical product, in particular to a numerically controlled lathe connecting piece and its heat treatment process. Background technique [0002] Some CNC lathe connectors on the existing market cannot resist elongation, breaking, slipping and wear, and the fatigue resistance and impact toughness are not high enough to resist fatigue and impact fracture, so they cannot be well used in CNC lathes. in the lathe. Contents of the invention [0003] The invention provides a numerically controlled lathe connecting piece and a heat treatment process thereof. [0004] The purpose of the present invention is to solve the problem that some existing CNC lathe connectors do not have high enough tensile strength to resist elongation, breaking, slipping and wear, and the fatigue resistance and impact toughness are not high enough to resist fatigue. And impact fracture, can not be well applied to the problem of CNC lathes. [0005] Th...
