The Chinese patent discloses a "pneumatic fixed fixture for numerical control machining of die templates", with the application number "CN202223379724.0", which includes a workbench. An air pump and an air chamber are installed at the top of the workbench. A movable rod is slidably sleeved on the air chamber. A connecting frame plate is fixedly arranged on the movable rod. A return spring is arranged between the air chamber and the connecting frame plate. A guide groove is opened at the top of the workbench. A stable guide plate is slidably clamped in the guide groove. A clamping plate is arranged on the connecting frame plate. By symmetrically arranging guiding structures on both sides of the clamping plate on the workbench, the shaking of the clamping plate is avoided, and the moving guiding accuracy of the clamping plate on the pneumatic fixed fixture for numerical control machining of die templates when clamping the die template is improved. By symmetrically arranging handrail frames on the surface of the workbench, handrail rods are arranged on the handrail frames, and at the same time, two groups of caster structures are symmetrically arranged at the bottom of the workbench, the overall flexible mobility of the pneumatic fixed fixture for numerical control machining of die templates is improved.
