Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Referring to fig. 1 to 3, in an embodiment of the present invention, a tooling fixture for an aircraft stopper is used for clamping a stopper 2 as shown in fig. 2, the stopper 2 is integrally U-shaped, a cylinder 23 is disposed in a middle position of a surface of the stopper, end surfaces of two ends of the cylinder 23 are respectively flush with front and rear side surfaces of the stopper 2, and curved arms at two sides of the stopper 2 are symmetrical with respect to an axis of the stopper 2 in a vertical direction. Strip-shaped bayonets 21 are formed on the bent arms on both sides, and bayonets 22 are also arranged on the stopper 2.

Referring to fig. 1, the tooling clamp comprises a base 1 and a pressing block 3, wherein the base 1 is of a plate-shaped structure and is symmetrically provided with vertical and upward positioning strip-shaped blocks 11 on two sides of the base, the top ends of the positioning strip-shaped blocks 11 are inserted into strip-shaped bayonets 21 on the bottom surfaces of bent arms of a limiter 2, notches 13 are formed in the middle position of the base 1 along the vertical direction, positioning clamping blocks 12 are inserted into the notches 13, the top ends of the positioning clamping blocks 12 are inserted into bayonets 22 on the bottom surfaces of the middle position of the limiter 2, the positioning strip-shaped blocks 11 on two sides of the base 1 are inserted into the strip-shaped bayonets 21 on the bottom surfaces of the bent arms on two sides of the limiter 2, and the positioning clamping blocks 12 are inserted into the bayonets 22 on the bottom surface of the limiter 2, so that the multi-point fixation of the limiter 2 is realized.

Briquetting 3 wholly is L type structure, including horizontal plate 21 and vertical board 32, and has seted up U type notch 311 on the terminal surface of horizontal plate 31, and the vertical board 32 of briquetting 3 erects on base 1 on the surface, and the horizontal plate 31 of briquetting 3 offsets with the surface of arrester 2, and 2 surperficial drums 23 of arrester are located the U type notch 311 of 3 horizontal plates of briquetting, and the horizontal plate through the briquetting further compresses tightly fixedly with the arrester, can realize the accurate positioning to the arrester, the processing of being convenient for.
