Technical Field
[0001] This utility model relates to the field of CNC machine tool technology, and in particular to a CNC machine tool positioning device for parts processing. Background Technology
[0002] A CNC machine tool is an automated machine tool equipped with a program control system. This control system can logically process programs with control codes or other symbolic instructions, decode them, represent them with coded numbers, and input them into the CNC device through an information carrier.
[0003] A patent with publication number CN217890207U discloses an auxiliary positioning device for machining high-end CNC machine tool parts. The device includes a base with two side plates symmetrically fixedly connected to its upper end. Each side plate has a through hole on its opposite side, and a drive shaft is rotatably sleeved within the corresponding through hole via a bearing. A fixing plate is fixedly connected to one end of each drive shaft facing away from the other. A common support tube is fixedly connected to the center of the opposite sidewall of the two fixing plates. Four partition baffles are evenly fixedly connected to the wall of the support tube.
