Machining tool for multiple types of shifting forks of tractor

The utility model relates to a machining tool for multiple types of shifting forks of a tractor. The clamp comprises a body and two sets of clamp sets arranged on the plane of the body. The two groupsof clamp sets are respectively used for positioning and pressing the two shifting fork parts; each clamp set comprises three pressing mechanisms and a positioning mechanism. During use, the two shifting fork parts are placed on the corresponding positioning mechanisms respectively, after the shifting fork parts are placed correctly, the adjustable limit is adjusted to enable fork openings of thetwo shifting fork parts to be concentric and then pressed through the pressing mechanism, a workpiece plane positioning mode is adopted for supporting and auxiliary supporting, and the auxiliary supporting mode is adjustable so as to adapt to the change of the size of a blank. The adjustable limit is transversely adjustable so as to adapt to shifting forks with different widths, the tool can be used for machining various t
