The existing hydraulic locking equipment for the vertical machining center has the problem of low locking precision, and when the existing hydraulic locking equipment for the vertical machining center works, the equipment adopts the positioning pin to lock the workpiece, and the positioning pin is operated by a worker, so that once the equipment works for a long time, the worker feels fatigue, a gap exists between the positioning pin and the workpiece, and the locking precision of the equipment is reduced;
when the hydraulic locking equipment for the conventional vertical machining center works, the type of a workpiece which can be fixed by the locking equipment is fixed, and the types of the workpieces are various, so that once the workpiece which is different from the equipment needs to be locked, the workpiece cannot be locked, and the working efficiency of the device is reduced;
when the hydraulic locking equipment for the conventional vertical machining center works, the locking equipment is fixed on the vertical machining center and has a certain service life, so that the locking equipment cannot be detached once being damaged, the locking equipment is inconvenient to maintain, and the practicability of the equipment is reduced;
the existing hydraulic locking equipment for the vertical machining center also has the problem that the vertical machining center is unstable, and when the existing hydraulic locking equipment for the vertical machining center works, the locking equipment is installed on the vertical machining center, and the vertical machining center is placed on the ground and is not fixed, so that once the equipment is collided, the vertical machining center is inclined, the equipment is further damaged, and the cost is increased.
