Shaft turning clamp for cross hole shaft part

The utility model relates to a shaft turning clamp for a cross hole shaft part, which comprises a base plate, a base plate arranged on the base plate and perpendicular to the base plate, a positioning block arranged on the base plate and located on one side of the base plate, and a core shaft arranged on the base plate and used for installing a machined part, and the core shaft and the positioning block are located on the same side of the base plate. The positioning block is in sliding connection with the chassis, and the position between the positioning block and the bottom plate can be adjusted through an adjusting device; when being used for machining the horizontal shafts perpendicular to the vertical hole, the horizontal shafts perpendicular to the vertical hole can be clamped and turned at a time, so that the part clamping frequency is effectively reduced, and the production efficiency is improved; secondly, the positioning element is reasonable in design, the positioning precision of the part is reliab
