The present utility model is mainly based on the following problems and findings:
at present, people usually adopt a simulation type block and magnet to adsorb to position and process the fairing body, a certain number of blocks are arranged on the length direction of the fairing to attach the fairing body, and then the magnet is adsorbed on the surface of the fairing body to ensure the flatness of the fairing body. Although the method can ensure the processing requirement of the flatness of the cover body to a certain extent, the magnet adsorption is difficult to completely ensure the positioning accuracy of the cover body along with the increase of the length and the processing number of the fairing. Therefore, the method of using the analog block and the magnet is only suitable for the condition that the length of the fairing is short and the number of the fairings is small. In addition, the inspection after the processing of the fairing is usually carried out with the cover body by setting up the mode of simulating the projectile body, adopts the bolt method to inspect the size and the precision of the extending hole of fairing side, but the selection of the size of the locating bolt will directly influence the accuracy of inspecting the size of the extending hole, especially when the angle tolerance of the extending hole is a limit value, because the diameter of the locating bolt is smaller, the condition that the inspection size is qualified and the actual installation of the product is abnormal easily appears in the inspection process. In general, the existing positioning and processing method for the side profile extension holes of the rectifying cover body is low in accuracy, complex in process and low in processing efficiency; meanwhile, the accuracy and rationality of the result are difficult to ensure by the existing inspection process for the side profile extension holes of the fairing.
For this purpose, in one aspect, the utility model proposes an assembly for machining and inspecting a fairing-side profile extension. As will be appreciated in connection with fig. 1-4, according to an embodiment of the present utility model, the assembly includes: the upper surface of the molding block 10 is consistent with the inner wall profile of the fairing 30; the pressure plate 20 is positioned above the fairing 30, and the pressure plate 20 is connected with the profile block 10.

1-2, the spacing distance between two adjacent mold blocks 10 can be 300-500 mm, for example, 350mm, 400mm or 450mm, and the inventor finds that if the spacing distance between two adjacent mold blocks 10 is too small, on one hand, the positioning difficulty of the fairing on the mold blocks is increased, the use flexibility of the assembly is reduced, and on the other hand, the manufacturing cost of the assembly is increased; if the spacing between two adjacent blocks 10 is too large, it is difficult to effectively position the fairing, increasing the risk of the fairing deforming during processing or inspection.
According to an embodiment of the present utility model, as will be understood in conjunction with fig. 2 to 3, the width of the profile block 10 may be greater than the width of the fairing 30, and in the direction of the fairing width, the portion of the profile block 10 beyond the fairing 30 may be located on both sides of the fairing 30 and may be provided with stepped platforms, and the pressure plate 20 may be connected to the stepped platforms.
