The invention discloses a small machining lathe fixture. The small machining lathe fixture comprises a flange plate connected with a machine tool, a fixed base mounted at the top end of the flange plate, a clamping mechanism arranged at the top end of the fixed base for clamping workpieces, an anti-loosening mechanism arranged in the clamping mechanism for improving the clamping performance of the device, and a reverse rotating mechanism arranged in the flange plate, connected with the clamping mechanism and used for once limiting the workpieces. Through arrangement of the anti-loosening mechanism, as a connecting groove and a polygonal block are limited, after a chuck is stressed, a lead screw cannot rotate, and the anti-loosening effect can be effectively achieved. 本发明公开了一种小型机械加工车床夹具，包括用于与机床进行连接的法兰盘；固定座，所述固定座安装在法兰盘的顶端；设置在固定座顶端的夹紧机构，用于对工件进行夹紧；设置在夹紧机构内部的防松动机构，用于提高装置的夹紧性能；设置在法兰盘内部的反向转动机构，并与夹紧机构相连，用于对工件的一次限位。本发明通过设置防松动机构，由于连接槽和多边形块进行了限位，夹头受力后，丝杆不会转动，可有效起到防松动的效果。
