Modularized jig frame structure

The utility model relates to a modularized jig frame structure. The modularized jig frame structure is characterized by comprising jig frame units, a plurality of jig frame units are combined in a circular array shape or a rectangular array shape to form a jig frame structure; the supporting vertical plates, the limiting clamping plates and the limiting locking hoops in the jig frame units are all of independent component structures, the supporting vertical plates, the limiting clamping plates and the limiting locking hoops are connected in a simple buckle inserting connection mode, and mounting and dismounting are more convenient and faster. Besides, the jig frame units can be arranged in a grid shape in an array mode, and the machining requirements of different workpieces can be met by adjusting the number of the jig frame units; all components in the jig frame units form modularization, the components can be replaced and combined with one another, the universality is high, and the flexibility degree is hig
