This utility model discloses a locking device for a high-precision four-axis machining center, relating to the field of machining technology. It includes a mounting base, with a locking mechanism fixedly connected to the top of the mounting base. A driving mechanism is disposed on the surface of the locking mechanism, comprising a screw, one end of which is rotatably connected to a rotating component. A mounting component is sleeved on the surface of the screw, and a second slide rail is fixedly connected to the surface of the mounting component. A pressure block is slidably connected to the surface of the second slide rail. Through the configuration of the driving mechanism, when locking a workpiece processed by the high-precision four-axis machining center, moving the pressure block upwards along the second slide rail directly pushes the screw to move, initially clamping the locking plate against the workpiece. Then, lowering the pressure block allows for a secondary locking of the workpiece by rotating the screw. Compared to conventional fixing methods, this requires a shorter thread feed distance.
