Abstract

The invention relates to a tooling for shaping the base of a fuel injector. The tooling includes a bottom plate, a splint, a skateboard seat, a nut, a nut seat, a screw, a hand wheel and a conical shaping block. On the bottom plate, the slide plate seat and the splint are perpendicular to each other, the nut is fixed on the bottom plate through the nut seat, the screw and the nut are threaded, one end of the screw is provided with a hand wheel, and the other end of the screw is provided with a conical shaping block; the injector base is passed through Clamped by the splint and the slide plate seat, the hand wheel is rotated to make the screw drive the conical shaping block to rotate, and the injector base is shaped by the rotation of the conical shaping block. Compared with the prior art, the present invention has simple structure, convenient manufacture and low cost; strong practicability, can reduce operation time and improve work efficiency; the tooling structure of the present invention is ingeniously designed, and the shaping effect is better than that of manual operation.

Description

technical field [0001] The invention relates to the technical field of auto parts, in particular to a tool used for shaping the fuel injector base. Background technique [0002] The base of the automobile fuel injector is an important part in the oil circuit of the automobile. The base of the fuel injector is a small workpiece with a strong reflective surface. The shape of the workpiece is irregular, slightly bowl-shaped, and there is a rounded corner at the edge of the bowl , the bottom is uneven, and there is an inner hole in the center. The base of the automotive fuel injector is made of metal precision stamping and internal grinding. Its inner diameter is generally about 13.6mm, and the precision of the inner diameter is required to be very high. This type of parts is mainly used for precision fit welding assembly with cylindrical parts. [0003] At present, many fuel injector seats are easily deformed after assembly. At present, deformed fuel injector seats can only b...
