The purpose of this utility model is achieved through the following technical solutions: a kind of band convex surface lid class part restructural fraise jig, it comprises pedestal, multiple back-up block, two pieces of blocks and pressing plate, the side of pedestal is provided with multiple fixed stop screwed hole, back-up block is arranged in groove, block is arranged on the both sides of pedestal respectively by the bolt coordinated with screwed hole, the back-up block that multiple height does not wait is installed and is arranged on pedestal, forms two head heights, middle low gradual change type curved surface on top.
Described pedestal offers many registration pin-and-hole group, and every registration pin-and-hole group is provided with multiple dowel hole, has a dowel hole to be provided with alignment pin in every registration pin-and-hole group, and alignment pin is used for axial location workpiece periphery.
Described groove is swallow tail shaped slot.
The two ends, top of center of asymmetry place back-up block are provided with the platform for placing pressure plate cushion block, platform are opened fixation clip screwed hole.
The top two ends of the back-up block at symmetrical centre place is provided with the locating slot of one group of symmetry, and locating slot is for installing positioning key, and locating slot and positioning key coordinate the location being used for workpiece periphery circumference.
The top shape of described back-up block is curved surface, and curved surface is for supporting workpiece.
Described block is provided with support column with the groove corresponding position on pedestal, offers through hole with the screwed hole corresponding position on pedestal, bolt, through hole and screwed hole coordinate both sides block being fixedly mounted on pedestal.
The shape of described support column is swallow-tail form.
The beneficial effects of the utility model are: it is by adopting the thought of modular fixture, and make fixture reconfigurability strong, wide accommodation, has the advantages that structure is simple, easy to use, fixture difficulty of processing is low.
