Rapid clamping device for machine manufacturing

The utility model relates to the technical field of clamping devices. The rapid clamping device for mechanical manufacturing comprises a box body, a threaded rod is fixedly arranged in the box body, the surface of the threaded rod is fixedly sleeved with a partition plate, moving modules are fixedly arranged on the two sides of the partition plate, the moving modules are movably connected with thethreaded rod, and a bottom plate is fixedly connected to the tops of the moving modules. The quick clamping device for mechanical manufacturing comprises a base, a threaded rod is arranged in the boxbody; the surface of the threaded rod is sleeved with a moving module; when the rotating wheel arranged on one side of the threaded rod is rotated; the moving modules on the surface of the threaded rod do relative or opposite movement; and the clamping device is further fixedly connected to the top of the moving module, so that mold products with different lengths can be installed and fixed, products needing to be machine
