Abstract

The utility model relates to a clamping device for large four-column hydraulic press movable worktables. A tapered side is arranged on the front side of a guide plate of the clamping device. When the initial cylinder moves forward, the tapered side is latched and is compressed tightly on a tapered block of a movable worktable. The further forward the cylinder rod of the initial cylinder moves, the more tightly the tapered block suppresses the movable worktable. At the moment, if the machining is done, the cam block of the hydraulic press up runs and withdraws, the movable worktable is imposed with an upward withdrawal reverse force. For the guide plate is movably connected with the initial cylinder, and the cylinder rod and initial cylinder are not forced. At the moment, the movable table and the guide block transfer the reverse force to the supporting structure. The supporting structure further transfers the reverse force to a straight key. Doing such not only protects the worktable from being collapsed, and prevents the movable worktable from uplifting by a tremendous reverse force and the gear drive mechanism from being deformed or damaged, thus eliminates the accident potential of the device and prolongs the service life of large hydraulic presses.
